The liquid absorbing particles are inorganic matter – expanded perlite, which is an inorganic, non-toxic, tasteless, non combustible, excellent liquid absorbing performance, good heat insulation performance and white granular appearance. It has the advantages of low price, convenient use and no secondary pollution after treatment. Because it is harmless to the environment, the product is widely used at home and abroad to prevent and control the leakage, oil spill and pollution of water surface (including water surface means of transport) and land chemical liquids. Hopetopway absorbent particles are hydrophilic, lipophilic, high liquid absorption rate, fast liquid absorption rate, good oil-water selectivity, easy to transport and store, can float on the water surface before and after liquid absorption, and have high oil retention rate. Compared with the products of other materials such as adsorption cloth, adsorption felt and adsorption powder, the new liquid absorbing particles have large adsorption capacity, good oil retention, high adsorption efficiency, reduced treatment time, reduced consumption in the oil cleaning process by 80%, and the cost is low.
