Dioctadecyl dimethyl ammonium chloride is a cationic surfactant with good surface activity and antistatic properties. Organic bentonite covering agent is a covering material applied to the surface of soil, usually used to control soil moisture evaporation and reduce soil erosion. Dioctadecyl dimethyl ammonium chloride has the following applications in organic bentonite covering agents.

1. Moisture control: Distearyl dimethyl ammonium chloride can combine with organic bentonite to form a composite material, increasing the adhesion and stability of the covering agent. The Distearyl dimethyl ammonium chloride in the covering agent can reduce the rate of water evaporation on the soil surface, help maintain the water content in the soil, and improve the growth conditions of crops.

2. Soil consolidation: Dioctadecyl dimethyl ammonium chloride has good surface activity and can promote the formation of a relatively strong covering layer of organic bentonite. The Dioctadecyl dimethyl ammonium chloride in the covering agent can form ion and hydrogen bonds with soil particles, increasing the bonding force between soil particles, thereby reducing soil wind and water erosion.

3. Anti static: The cationic structure and long chain alkyl groups of Di-hydrogenated tallow dimethyl ammonium chloride can effectively neutralize negative charges on the soil surface, reducing the accumulation and release of static electricity. The Dihydrogenated tallow dimethyl ammonium chloride in the covering agent can prevent static adsorption of soil particles, reduce soil surface adhesion, and reduce the risk of soil erosion.

4. Cover layer stability: The application of ARQUAD 2HT-75 in organic bentonite cover agents can increase the stability of the cover layer. ARQUAD 2HT-75 can improve the adhesion and erosion resistance of the covering agent, allowing the covering layer to remain on the soil surface for a longer period of time, preventing the floating and loss of the covering layer.
