1

Waste diatomite

900-041-49

Hydrogen containing silicone oil and filter aids silica and siloxane for methyl phenyl silicone resin filtration

Filter additives contain adsorbed silicone oil and silicone resin, which pollutes the environment

Handled by a third party with receiving qualification

Landfill after incineration or collaborative disposal in cement kiln after incineration

2

Waste oil residue

900-041-49

In the hydrolysis process of hydrogen containing silicone oil, due to its high hydroxyl content, it can not be separated from water. After a certain event, hydroxyl condensation occurs, and silicone oil forms solid oil residue polysiloxane.

Leakage can pollute the environment
