Sunny Keeper (granular calcium chloride) is a hygroscopic substance with excellent moisture absorption, strong deliquescence, easy solubility in water, and a property of not freezing 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 moisture absorption (desiccants). 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 wet 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 quick effects, while sodium chloride enhances sustainability. Additionally, both are used in food, making them safe and reassuring ingredients for people and the environment.

Q2: Why is it necessary to take measures against dust and to compact the ground? 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 take measures against dust to consider the surrounding environment. Furthermore, by regularly applying dust control measures, we can reduce soil erosion, which extends the cycle for replenishing or replacing soil and leads to cost savings.

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

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

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

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 to dissolve 1 kg of Boujin-kun in 1 L of water and simply apply it to the weeds. Compared to commercially available chemicals, its effectiveness is inferior, 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.

Q7: What about salt damage? A: There is a risk of rusting on metals, so please be sure to wash with water after using tools like shovels during application. Additionally, regarding Q6, it may seem that having nearby fields could negatively affect crops, but magnesium chloride can actually act as a fertilizer in small amounts. Therefore, even if some components are washed away by rain and become extremely diluted, I believe there is no particular problem. However, I recommend applying it as carefully as possible.

Sunny Keeper is formed from flake-shaped magnesium chloride (MgCl2·6H2O). Utilizing the properties of Sunny Keeper, such as freezing point depression, hygroscopicity, and water retention, it is widely used not only as a freeze prevention agent but also for soil stabilization and dust control. It is hygroscopic, releases heat upon dissolution, and significantly lowers the freezing point of water, making it highly effective for snow melting, ice melting, and freeze prevention. Additionally, it reacts with calcium, iron, aluminum, and other components in the soil, causing a solidification phenomenon that appropriately compacts the soil and forms a resilient soil structure. This helps prevent surface roughness and soil erosion. Furthermore, due to its extremely strong hygroscopicity and water retention effect, it absorbs moisture from the air to maintain adequate surface humidity and prevent the scattering of dust.
