Sunny Keeper (granular calcium chloride) is a chloride of alkaline earth metals that has excellent hygroscopicity, strong deliquescence, easily dissolves in water, and does not freeze even at very low temperatures. The applications of Sunny Keeper are diverse, including freeze prevention, dust control on roads and sports fields, de-icing agents, and hygroscopic (desiccant) uses. When Sunny Keeper is spread in areas prone to dust (such as grounds and tennis courts), it deliquesces with moisture in the air and soil, becoming moist and demonstrating dust control effects. Furthermore, over time, it reacts with calcium to increase the strength of the topsoil. For more details, please contact us or refer to the catalog.

Q1: What are the ingredients of Boujin-kun? A: The main ingredient is magnesium chloride, which is also used as a coagulant for tofu, with the addition of sodium chloride (salt). Magnesium chloride provides immediate effects, while sodium chloride enhances durability. Additionally, both are used in food, making them safe and reassuring ingredients for people and the environment.

• Chemicals

Q2: Why is it necessary to take measures against dust and to compact the soil? A: Many school playgrounds are made of soil, and during the dry summer and winter months, dust can be raised. This dust is harmful to health and is said to be one of the causes of conditions like conjunctivitis. Additionally, if there are residential areas, businesses, or stores nearby, it is necessary to consider the surrounding environment and take measures against dust. Furthermore, by regularly applying dust control measures, we can reduce soil erosion, which leads to longer cycles for soil replenishment and replacement, ultimately resulting in cost savings.

• Chemicals

Q3: Why does it help prevent dust? A: When you spread Boujinkun on the surface of the soil, it absorbs moisture from the air and the soil, causing it to deliquesce (the phenomenon of a solid dissolving into a liquid) and maintain moisture retention. This effect is utilized to prevent dust in places like sports fields.

• Chemicals

Q4: What is the difference between dust prevention and compaction? A: Soil compaction is necessary for creating conditions during the replenishment of soil on tennis clay courts and fields. By spreading approximately 1 kg to 1.2 kg per square meter on the surface, it combines with calcium, iron, and aluminum in the soil to moderately compact the soil texture. However, soil on baseball and soccer fields is not beneficial for users if it is too compacted. In such places, dust prevention is implemented while maintaining appropriate elasticity, so approximately 500 g is spread per square meter.

• Chemicals

Q5: What is the duration of effectiveness? A: The duration of effectiveness is greatly influenced by the usage environment of the field and weather conditions, but it typically lasts for 1 to 2 months after application. If applied 4 to 5 times a year, you can enjoy comfortable sports throughout the year.

• Chemicals

Q6: Please tell me about the weeding effect. A: The main ingredient of Boujin-kun is chloride, which has the effect of killing weeds. The method of use is simply to dissolve 1 kg of Boujin-kun in 1 L of water and spray it on the weeds. Compared to commercially available chemicals, its effectiveness is lower, but in places like schools, safety in use and storage is prioritized, so it is mainly used as a substitute in kindergartens and elementary schools.

• Chemicals

Q7: What about salt damage? A: There is a risk of rusting on metals, so please be sure to wash with water after using a shovel or similar tool during application. Additionally, considering Q6, it may seem that having nearby fields could negatively affect crops, but magnesium chloride in small amounts can actually act as a fertilizer. Therefore, even if some components are washed away and extremely diluted by rain, I believe there won't be any significant issues. However, I recommend applying it as carefully as possible.

The desiccant "OZO" has a moisture absorption rate that is approximately 6 to 7 times higher than that of silica gel, allowing it to be effective with only 1/6 to 1/7 of the usage amount. It is all-weather capable, able to absorb moisture not only in high temperature and humidity but also in low temperature and low humidity environments. Additionally, it hardens and solidifies upon moisture absorption, and the absorbed water is stored as crystallized water, resulting in minimal moisture release. This product is committed to reducing waste (zero mission) by reviewing raw materials and manufacturing processes as part of environmental problem measures. 【Comparison of moisture absorption rates between OZO-Z and Silica Gel Type A】 ■ Measurement conditions: 40°C, 90% RH ■ Days: OZO-Z / Silica Gel Type A - 2 days: 94.88 / 33.3 (%) - 16 days: 219.96 / 35.84 (%) - 34 days: 255.28 / 35.38 (%) For more details, please refer to the catalog or feel free to contact us.
