The "Dash Sheet DBS-10" is a product that quickly absorbs water simply by being taken out of the package and placed down. After use, it can be air-dried in the sun for about 3 to 4 days, during which it gradually decomposes due to ultraviolet rays and releases moisture. To promote dehydration, it can be placed in a calcium chloride solution with a concentration of about 15%, where it will completely release moisture in about 15 minutes per sheet, after which it can be disposed of as combustible waste. It can be used for various situations such as flooding in buildings, flooding in elevator machine rooms, water leaks in plumbing systems, and flooding at construction sites. 【Features】 ■ Quickly absorbs water just by being taken out of the package and placed down ■ Can respond quickly in emergencies ■ Absorbs 10 liters in about 5 minutes ■ Can be treated by air-drying or using calcium chloride, and can be incinerated *For more details, please refer to the PDF document or feel free to contact us.
