Silica can be treated with suitable compounds to make it a surface hydrophobic substance. There are two main treatment methods: liquid phase method and gas phase method. The conditions of the liquid phase method are easy to control, the product quality is stable, and the treatment effect is good, but the process is complicated and the solvent needs to be recovered; the gas phase method has a simple treatment process, but the quality of the product is not stable enough and the treatment effect is poor.
