第一化工 List of Products and Services

At Daiichi Chemical Co., Ltd., we perform "thermal spraying," which involves melting metals, ceramics, and other materials using heat sources such as gas and electricity, and then spraying them onto a substrate to form a coating. In accordance with JIS and ISO standards for "corrosion protection thermal spraying," we can adjust the spraying materials based on the installation environment of the structure and the coating thickness according to the expected lifespan. Additionally, thermal spraying of stainless steel, nickel-chromium, and Hastelloy has proven to be extremely effective for the inner surfaces of chemical storage tanks. 【Features of Thermal Spraying】 ■ Wide range of materials ■ Applicable to large structures such as bridges and transmission towers, with on-site construction possible ■ Thick coatings can be relatively easily produced, and the coating process is faster compared to other surface treatment methods ■ Relatively low thermal impact on the substrate, making deformation and distortion less likely *For more details, please download the PDF or feel free to contact us.

At Daiichi Chemical Co., Ltd., we handle "shot peening," a type of surface treatment that utilizes shot blasting to increase the surface hardness of steel surfaces. This process enhances fatigue strength by applying compressive residual stress to the surface layer, which counteracts repeated loading. The benefits include improved wear resistance, enhanced stress corrosion cracking resistance, better heat dissipation, and reduced fluid resistance. Additionally, harmful tensile residual stresses generated by welding or heat treatment can be easily converted into compressive residual stresses through peening. 【Features】 ■ Speed of the projected steel balls: approximately 40 to several hundred m/s ■ Size of the steel balls: approximately 0.5 mm to several mm ■ Support for on-site work *For more details, please download the PDF or feel free to contact us.
