On July 4, 2001, during a flood control and emergency leak-plugging drill organized by the Henan Yellow River Bureau, the flood control expansion bags produced by Hebei Five-Star Power Equipment (Shijiazhuang) Co., Ltd. were used to seal leaks. From the moment the team entered the water to the successful completion of the task, it took only 2 minutes, with excellent air-tightness. The attending experts unanimously agreed that the flood control expansion bags developed by Hebei Five-Star Power Equipment Co., Ltd. feature small size, light weight, simple operation, rapid water absorption and expansion, and effective emergency sealing, making them highly valuable for promotion and application.

Hebei Five-Star Power Equipment Co., Ltd.'s water-absorbing expansion bags are characterized by simple operation, portability, fast water absorption and expansion, time and labor savings, and excellent emergency protection effects. They can be widely used for engineering flood control, emergency response, sealing dike leaks, overflow protection, temporary heightening of flood control dikes, construction of temporary waterproof walls, slope protection and scour prevention, engineering flow interception, and blocking of hidden ditches or tunnels. They can replace sandbags filled with soil for emergency operations, reducing manpower and improving response speed, offering broad promotion and application value.

Introduction to Hebei Five-Star Power Equipment Co., Ltd.'s Water-Absorbing Expansion Bags for Flood Control:

Hebei Five-Star Power Equipment Co., Ltd.'s water-absorbing expansion flood control bags are a new waterproof product that is easy to store and simple and quick to use. The outer bag is made of highly permeable linen or cotton materials, tailored into different specifications and shapes for various uses, while the inner bag contains specially designed water-absorbing materials.

At Five-Star, we firmly believe that water-absorbing expansion bags are critical for flood control, representing a long-term strategy that concerns national assets and public safety. Therefore, we adhere to integrity and honesty in both our conduct and work.

Currently, the market for water-absorbing expansion bags is mixed with counterfeit products from small factories. These manufacturers engage in malicious price competition without regard for product quality, prioritizing profit above all else. Below, we analyze the composition of expansion bags from other manufacturers compared to our Five-Star Power water-absorbing expansion bags:

Water-absorbing expansion bags contain polymer water-absorbing materials. Hebei Five-Star, leveraging American technology, uses finely produced high-concentration polymer expansion materials, with an addition of 185 grams. In contrast, counterfeit expansion bags from other manufacturers use raw materials produced through simple methods and secondary refining of recycled products, with an addition of less than 160 grams. This significantly reduces their costs, allowing them to sell at lower prices.

However, at Five-Star, we insist that water-absorbing expansion bags are crucial for flood control, representing a long-term strategy that concerns national assets and public safety. Therefore, we adhere to integrity and honesty in both our conduct and work.

Inferior expansion bags have a water absorption expansion rate approximately 60% lower than our Hebei Five-Star products, and their expansion speed is twice as slow. The water-absorbing materials used in these inferior products, due to their secondary refining process, volatilize extremely quickly, often dissipating entirely within a few months. According to national technical requirements for flood control materials, water-absorbing expansion bags should have a shelf life of four years. These inferior product manufacturers focus only on short-term profits, rendering the bags useless in urgent flood control situations, with potentially severe consequences!

We hereby remind consumers to recognize reputable brands and choose carefully!
