This product is exposed to wind, rain, and ultraviolet rays on the outside, and water flows inside, so painting is necessary. First, a type of shot blasting was used for surface preparation to remove dirt and uneven areas. After that, three layers of paint were applied. Since the painting specifications differ between the exterior and interior of this product, masking is done to prevent paint from getting on the inner surface before painting. The outer diameter is approximately φ3000, and the weight is about 5 tons. For the exterior painting specifications, a two-component polyamide amine cured modified epoxy resin is used for the primer, the same type of resin for the intermediate coat, and a two-component polyamide amine cured modified epoxy resin enamel for the top coat, resulting in a total film thickness of 120 μm. This product is finished without defects such as drips, painting flaws, or insufficient film thickness.

"Approaches to Improving Coating Quality" The causes of defects and troubles that occur in the coating process can be classified into five categories: 1. Defects due to the condition of the substrate 2. Defects due to the quality of paint or solvents 3. Defects in coating equipment or facilities 4. Defects in application methods or conditions 5. Defects due to the application environment These issues can be avoided through proactive measures. However, defects caused by the application environment may require capital investment or process changes. Nevertheless, by adjusting processes according to weather conditions and managing delivery schedules, troubles can be avoided. When coating defects occur, the corrosion resistance and appearance of the product are diminished, necessitating corrections through sanding or stripping the coating. This is a labor-intensive and time-consuming task that also incurs costs. Therefore, it is essential to address the causes in advance to improve coating quality.

The breakdown of life cycle costs consists of six components: construction costs, operating costs, utility costs, repair costs, management costs, and disposal costs. Construction costs include planning and design costs, material costs, manufacturing costs, transportation costs, and on-site construction costs. On the other hand, operating costs include security costs, cleaning costs, and maintenance and inspection costs. Utility costs encompass expenses for water supply and sewage, gas, electricity, and so on. Repair costs require expenses for regular maintenance, equipment and parts replacement, and repairs. Management costs include operating costs, taxes, and insurance costs. Finally, disposal costs involve expenses related to demolition. Initial costs account for about 20-25% of the total for many structures and products, which is surprisingly low. However, the composition of running costs can vary significantly depending on the use, and renovation and repair costs may exceed construction costs. Large structures, such as bridges, were built in large numbers during the period of rapid economic growth, but they are now aging. Since it is not realistic to replace all buildings with new ones, appropriate renovation and repair work is crucial. To ensure safe use over a long period, it is necessary to properly understand and manage life cycle costs.

Rather than elements such as excellent equipment or high-performance paints, proper surface preparation is the most important factor. Surface preparation is the process of preparing the surface to be suitable for painting, which includes cleaning, removing impurities, and roughening or smoothing the surface. Surface preparation greatly affects the lifespan of the paint, with the proportion of substrate adjustment reaching as high as 49.5%. There are three benefits to surface preparation: removing impurities, improving adhesion, and achieving a beautiful finish. In painting work, meticulous surface preparation is carried out to prevent painting defects.

When comparing products that only have a topcoat without a primer to standard painting products that include a primer, it was found that the products without a primer easily had their paint film peel off. Primer paint has the dual effect of preventing rust and strongly adhering to the substrate and underlayer, making it indispensable. Although the primer is not visible, it plays an important role in maintaining corrosion resistance. Additionally, if the primer is not applied properly, the topcoat may be unevenly applied or have inconsistencies, resulting in an unattractive finish. Furthermore, the primer enhances the permeability of the paint, allowing the topcoat to adhere better, which can improve the durability and anti-corrosive properties of the paint film. In other words, the primer is a crucial step that significantly affects not only the appearance but also the performance and lifespan of the paint. Therefore, skipping the primer can lead to a higher likelihood of peeling paint and rust-prone products, making it essential to always apply the appropriate primer.

We compared samples with and without a primer. For surface preparation, we degreased with cleaning thinner and roughened the surface with sandpaper. The painting specifications used epoxy-modified resin paint for the primer and acrylic-modified phthalic resin paint for the topcoat. After allowing sufficient drying time, tests were conducted. When removing the masking tape, the sample without primer had the paint peel off with it. The primer has a high adhesion to the substrate, and when used together with the topcoat, it maximizes the performance of the paint. Skipping the primer may result in a visually appealing finish, but the performance of the paint is compromised. By performing blast processing, a more robust paint film can be formed. Omitting the primer reduces the adhesion of the paint, making it more prone to peeling and crumbling. The combination of primer and topcoat allows the paint to adhere to the surface, enhancing the strength and durability of the paint film. The primer is an essential step to maximize the performance of the paint and ensure quality. While it is possible to shorten the process by omitting it, this will impact the durability and quality of the paint job.

Lining products that are often discarded or left unused. However, when used for a long time, the rubber, resin, and plating on the surface can deteriorate and rust. It is also difficult to reline them, and a clean stripping through blasting treatment is necessary. Harada Iron Works' blasting creates a fine uneven surface, improving adhesion and transforming the product into one that lasts longer. Compared to making new similar products, it can be done overwhelmingly 'faster' and 'cheaper.' Harada Iron Works has its own grit blast and sand blast equipment. This blasting process is suitable for products that have the option of being discarded or reused. For example, it is effective not only for the reuse of rubber linings but also for surface treatment of steel materials, machine parts, ships, tanks, and more. The blasting process completely removes surface dirt and deteriorated layers, providing a perfect pretreatment for new coatings. Additionally, Harada Iron Works' blasting equipment uses its own grit blast and sand blast systems. These are environmentally friendly and allow for efficient work. Furthermore, the large size of the equipment enables it to handle large products as well.

Castings made by melting metal and pouring it into molds tend to have burrs and residues from the mold material, which are removed through blasting treatment. Blasting uses abrasive materials to grind the surface and create texture, enhancing the adhesion of paint. Castings can be produced in large quantities and come in two types: die-cast and sand-cast. Die-casting is excellent in wear resistance but is costly and suitable for mass production, while sand-casting is inexpensive and can accommodate complex shapes. Harada Ironworks manufactures its own blasting equipment with dimensions of 6m in width, 10m in depth, and 3m in height. Additionally, blasting treatment is utilized not only for surface cleaning but also for modification and shape processing. For example, by performing blasting treatment on metal products, the surface strength can be improved, making it easier to apply resin or paint. Furthermore, applying blasting treatment to hard materials such as glass and stone can express beautiful textures and designs. Our blasting equipment is large-scale and manufactured in-house to accommodate a wide range of applications, allowing us to respond flexibly to customer needs.

What you requested from us is an in-house jig. Unfortunately, the product had been used for many years, resulting in peeling paint and advancing rust. This jig is old, and there are no existing drawings, so new production would require time and budget. Therefore, we only performed modifications and repairs on the necessary parts, along with repainting. First, we removed the paint and rust using blasting (type 1 surface preparation) and conducted surface treatment. After that, we applied a primer and topcoat, completing the product. This product measures 1500×1500 L=2500, and we used grid blasting and surface preparation according to SSPC SP-10. Additionally, we applied one coat of epoxy-modified alkyd resin primer and one coat of synthetic resin blended paint for the topcoat. The repair and modification took only 4 days. It took a bit longer due to the need to differentiate the painting of the main frame and the handrails and ladder, but we were able to accommodate the short delivery time. After blasting, the painted product became remarkably clean and its durability improved. Harada Ironworks Hiroshima Official Link

The rolls have aged, and the rubber has worn out and become unusable. In addition to the rubber, there are also issues like rust, so first, we will cleanly strip the rubber using a blast, and then we will reapply the rubber. It's pleasing to see the product beautifully revived! Please note that our company cannot handle rubber application work. Since the process of removing the rubber takes time, we will first strip the rubber from the rubber rolls using grit blasting after they arrive. Then, just before shipping, we will completely remove the rust with sandblasting and prepare for shipment. By removing the rubber and rust and reapplying the rubber, the product will be in like-new condition. Furthermore, the blasting creates a rough surface, which increases the surface area, improves the adhesion of the rubber, and enhances the durability of the product.

This plate is quite corroded and covered in rust. However, all the rust can be completely removed through blasting treatment. Normally, when rust occurs, it is common to use sandpaper, disc sanders, or power brushes to scrub it off. However, if the corrosion is extensive or deep, it may not be completely removed. In such cases, blasting treatment can completely eliminate the rust. For base materials with advanced rust, it is necessary to perform rust prevention treatment immediately after surface preparation through blasting. Even a short period of 1 to 2 hours without rust prevention treatment can lead to further rust progression and darkening of the surface, so caution is required. The "lifespan of the paint" on metal products, or rather the "lifespan of the product," is greatly influenced by the preparation of the base material! No matter how high-quality the paint used or how advanced the application techniques are, the thoroughness of the cleaning of the base material before painting has a significant impact.

The interior is untreated, and only the exterior has been painted. The tank is large, with dimensions of 2500mm in diameter and 4400mm in height. The specifications include painting after blast treatment, with a salt-resistant coating. First, impurities and rust on the surface were removed by blasting, and then a total of six layers of paint were applied, including inorganic zinc, thick-film epoxy resin, and urethane resin. Although not shown in the photos, the handrails and stairs were also painted, with the top coat being yellow. Even with such a large tank, painting was carried out without issues due to the number of overhead cranes and the spacious painting area. The delivery time was a bit short at just over a week, but by using cranes for the painting, we were able to reduce the labor involved in flipping the tank and managed to meet the scheduled delivery date.

Our company owns a manual blast facility with dimensions of 6m in width, 10m in depth, and 3m in height, which can accommodate the processing of complex fabricated products. This facility can be applied to various purposes, including surface preparation before anti-corrosion treatment, paint stripping for maintenance items, removal of oxide films after heat treatment, and improving adhesion through increased surface area. We used SS400 products as test pieces and verified the results by changing only the abrasive material while using the same equipment and air pressure. For grit blasting, we used IKK steel grit TGE-100, and for sandblasting, we used NeoBlast G-1. The results were as expected, with both methods effectively removing scale and rust. However, there were clear differences in surface roughness and appearance. Grit blasting resulted in a slightly rougher surface, while sandblasting produced a somewhat dull finish. At our company, we differentiate between sandblasting and grit blasting based on the size and material of the workpieces, recommended surface roughness, and whether masking is required. By utilizing the characteristics of each method and performing optimal processing, we achieve high-quality finishes. Harada Iron Works Hiroshima Official Link

This time, we will apply blast treatment and inorganic zinc coating to a frame measuring 10m in length and 2m in width. Inorganic zinc is officially referred to as "inorganic zinc-rich paint" and "inorganic zinc-rich primer." The difference between these two lies in the distinction between thick film type and thin film type, which can be a bit complicated. For this project, we used the thick film type of inorganic zinc-rich paint. This paint contains a large amount of zinc powder and is specifically designed for priming. Zinc has a greater tendency to ionize than iron, making it more prone to rust. Therefore, the paint serves to protect the iron by rusting in its place. Due to its corrosion-resistant properties, it is commonly used in harsh environmental conditions, such as on large ships, bridges, and plants.

After degreasing the flat bar, it will be coated with a two-layer specification. When using a spray gun, the work efficiency decreases compared to airless spraying, but it minimizes paint loss, allowing for painting with a small amount of paint. Additionally, while the types of paint that can be used are limited, the paint particles sprayed are finer than those in airless painting, resulting in a beautiful finish. Airless spray is a method that atomizes the paint under pressure without using air, spraying it in a mist. It is specialized for achieving thicker film thickness and painting large products. On the other hand, air spray simultaneously injects air and atomized paint for painting. The particles of the atomized paint are fine, allowing for uniform and beautiful painting. However, due to the high amount of overspray, the transfer efficiency is lower.

After blasting a massive pipe weighing 2 tons and measuring 5 meters in length, we will perform underwater painting. A minimum film thickness of 300μm is required for the underwater painting. If the film thickness becomes too thick, there is a risk of peeling, so we will also pay attention to the upper limit of the maximum film thickness while painting. If the set values for the upper and lower limits are too close, the work becomes difficult. To meet these conditions, we repeated inspections and corrective painting multiple times. Ultimately, we achieved a perfect finish within the range of 300μm to 600μm.

Here is a concise summary of grit blasting and sandblasting with the following characteristics: **Characteristics of Grit Blasting:** The abrasive material is metallic and has very high grinding power, easily removing adhered rust and dirt. It can also remove rubber, plating, and paint from the surface of products. Compared to other abrasives, it causes less wear when striking the target, resulting in less dust and waste. However, since the raw material is metallic, there is a possibility of "transferred rust" occurring when applied to materials that are less prone to rust, such as stainless steel. **Characteristics of Sandblasting:** In the past, "silica sand" was used as an abrasive, but now mainly "ferro-nickel slag," a non-metallic abrasive, is used. Because a non-metallic abrasive is used, it can be applied to materials that are less prone to rust, such as stainless steel. It has less grinding power compared to grit blasting, allowing for careful application on soft metals and products with extensive masking. If you have a specific abrasive in mind or have inquiries about other application uses, please feel free to contact us. Harada Iron Works Hiroshima Official Link

In the first part, we introduced the preparation work and blasting, but now we will move on to the painting work. This time, we used a thick film type paint that excels in heat resistance. This paint achieves a film thickness of 100 to 200 μm with a single spray, and the maximum heat resistance temperature is 600°C! The weather resistance due to the thickness of the paint film is also excellent. However, this paint is prone to clogging, so we used the Turn Double Chip from Seiwa Sangyo Co., Ltd. By using this chip, we can reduce paint clogging. There are methods to increase the dilution ratio or to use a larger chip diameter, but the reasons for choosing this chip are as follows. Increasing the dilution ratio would result in a thinner film thickness, and increasing the chip diameter would lead to more paint loss. Therefore, following the recommended values from the paint manufacturer, using this chip became the optimal choice. The construction period was 5 working days. The preparation work took 2 to 3 days, and blasting and painting took 2 days. Since the number of days for preparation work affects the order volume, we look forward to specific inquiries regarding requests that include preparation work.

The large steel plate, measuring 2600×2300 and weighing 5 tons, made of SS400 PL100t, will have its rust removed through grit blasting. While the specific application is unknown, completely removing the rust from this steel plate and applying anti-corrosion treatment will protect the base material from corrosion. Corrosion is a phenomenon where the surface changes due to scientific or electrical factors, impairing its appearance and function. If it progresses, it can lead to a reduction in thickness and the formation of holes. In contrast, anti-corrosion treatment is performed to stop or delay the corrosion of metal materials. Corrosion resistance refers to the ability of the metal material itself to withstand corrosion, while anti-corrosion and rust prevention aim to prevent the corrosion of metals. In this context, blast treatment of steel plates is commonly used. Harada Ironworks Hiroshima Official Link

There are mainly two types of film thickness gauges. Wet film thickness gauge: This type of gauge is used after applying liquid paint, before the paint film has fully cured. By accurately measuring the thickness of the paint film, it allows for understanding the film thickness at the time of application. Wet film thickness gauges help in quality control during the application process and in saving paint. Dry film thickness gauge: This type of gauge is used after the applied paint film has completely cured. Dry film thickness gauges are utilized to measure the thickness of the paint film after the painting work is finished, confirming the quality of the finish. By accurately measuring the thickness after curing, it can be determined whether it meets the painting specifications. For more details, please refer to the PDF below.

The lifespan of metal coatings is generally considered to be around 10 to 30 years. The factors that influence this lifespan can be broadly categorized into the following four: Surface Preparation: Proper adjustment of the metal surface before painting is crucial. Cleaning and treating the surface improves the adhesion and durability of the coating. Number of Coats: Adhering to the appropriate number of coats is also important. Ensuring sufficient coating thickness enhances the corrosion resistance of the metal. Type of Paint: The type of paint used significantly affects the lifespan. It is necessary to select the appropriate paint that matches the metal's usage environment, considering factors such as weather resistance and chemical resistance. Painting Techniques, Climate, and Surrounding Environment: The skill of the painting process and the construction environment are also important factors. By using appropriate painting techniques and considering climate conditions and the surrounding environment, the quality and lifespan of the coating can be improved. By properly managing these factors, the lifespan and corrosion resistance of metal coatings can be maximized. For more details, please refer to the PDF below.

If you have any requests for sandblasting or grit blasting in Hiroshima, please feel free to consult us. Blasting is a type of surface treatment process that involves colliding various particles with a material to remove surface layers and create texture. Its effects are as follows: Surface cleaning: It removes oxide films, rust, and dirt, achieving a clean surface. Improved adhesion: The increase in surface area due to the formation of texture creates an "anchor effect," enhancing adhesion with the paint. The durability of the paint is influenced by various factors such as the number of coats and the type of paint, but the impact of the grade of surface treatment can be as much as 50%. Surface preparation is the most important factor in painting.
