Sandbag for Flood Control and Fire Protection - Leakage-proof, Water-absorbing and Expansion Bag for Flood Season
There are more than 100 kinds of products in flood control and rescue materials. The classification and products of flood control and rescue materials we commonly use are basically in the following areas:20Among them, one product is an emergency rescue water-retaining material which has been used since ancient times, namely, water-absorbing expansion bag.
Water absorbent expansion bag is mainly made of macromolecule water retaining agent as the main material of rapid expansion of fixed water source, using the most advanced in the world.The scientific concept of "water plugging" is to immerse in water-absorbing expansion bags2-3It can expand rapidly in minutes, so as to achieve the fastest speed of water plugging and leak plugging and flood control at the breakwater or breach where a flood occurs. Sandbags can be replaced in emergency rescue when water is blocked. After testing by relevant departments, the emergency water shutoff efficiency of water absorbent expansion bags is about ten times higher than that of ordinary sand bags, which is another flood control tool. The absorbent expansion belt itself is small in volume and light in weight. It is as light and foldable as ordinary household cloth bags, and it is convenient for transportation and storage. Let's look at the specifications of the absorbent expansion bag.
