Water-absorbent expansion bags, also known as expansion flood-proof bags and flood-proof sacks, are a new waterproof product that is easy to store, simple and fast to use, and is convenient and simple to use. It is composed of linen or cotton materials with good water permeability, outer bags of different specifications and shapes according to different uses, and special water-absorbent materials for the inner bag. Inflatable flood-proof bags are small in size before use, light in weight, and easy to store and transport. Compared with traditional sandbags, it greatly reduces time and manpower during flood prevention and rescue operations, and makes flood prevention and rescue operations more efficient.
The water-absorbent expansion bag is an environmentally friendly product, non-toxic, harmless, odorless and pollution-free. When not in use, the flood-proof bag should be placed in a dry place indoors for backup. It can be used at any time during storms or typhoon rainy seasons to prevent floods and absorb water.
. When in use, open the bag, immerse the bag in the nearest water or directly wait for the flood control to be sprayed with water. The bag can expand twice (approximately) in about minutes, and then move to the required place for flood control and interception.
. After the flood recedes, the flood-proof bags that have not absorbed water can be placed back indoors in a dry place for sealed storage. The flood-proof bags that have absorbed water can be left to dry naturally and be disposed of as waste. They are non-toxic, harmless and pollution-free.
