The adsorbed particles have a multi microporous structure inside, which has strong adsorption capacity for leaked pollutants such as diesel, gasoline, engine oil, No. 2 flotation oil, toluene, xylene, kerosene, nitrobenzene, formaldehyde, methanol and ethanol, and can adsorb pollutant liquid equivalent to 6 times its weight (about 5-6 kilograms of oil and chemical liquid can be adsorbed per kilogram of adsorbed particles). Without treatment after adsorption, it will become very dangerous to be exposed to air all the time. Moreover, hopetopway adsorption particles also have hydrophilicity, lipophilicity, large liquid absorption rate, fast liquid absorption rate, good oil-water selectivity, easy transportation and storage, and can float on the water surface before and after liquid absorption, with high oil retention rate. Compared with the products of adsorption cloth, adsorption felt, adsorption powder and other materials, the new adsorption 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.
