| titleOfInvention | Processing method of perlite oil absorbent for absorbing oil stains on water surface |
| abstract | The invention discloses a preparation method of a perlite oil absorbent for absorbing oil stains on water surface, which comprises the following steps: step S1, selecting perlite ore sand which comprises, by mass, 72% -75% of silicon dioxide, 15-18% of aluminum oxide, 0.5-1% of ferric oxide, 2.9% -3.5% of sodium oxide, 0.5-2% of calcium oxide, 2.5-3% of potassium oxide, 0.1% -0.4% of manganese oxide and 4-6% of water, and screening out the perlite ore sand with a proper particle size of 0.2-0.5 mm as a raw material; step S2, putting perlite ore into a preheating furnace for preheating; step S3, putting the preheated perlite ore into an expansion furnace for high-temperature roasting to achieve instant expansion; step S4, carrying out hydrophobic film coating treatment on the surface of the expanded perlite ore to prepare perlite oil absorbent particles for absorbing oil stains on the water surface; the perlite oil absorbent particles prepared by the method have light weight and high porosity, can be suspended on the water surface for a long time, have high oil floating rate on the water surface, and can effectively recycle the adsorbed floating oil. |
