The main products are rice husk extracting plant-derived natural nano-silica, steam, liquid soil conditioner, and natural nano-silica. Features 1. The primary particle size is 30-50 nanometer spheres. 2. The surface of the primary particle size sphere is covered with walnut patterns. 3. It has natural three-dimensional nano-level holes. 4. The product quality and safety are much higher than the food additive standard. 5. After airflow pulverization The minimum D50 can reach 1 micron. The product has a very good effect in agricultural fields such as solid slow-release nano-silicon fertilizer, liquid nano-silicon fertilizer, soil amendment, obstacle soil remediation, and saline-alkali soil transformation. The industry is oriented to rubber, toothpaste, food, pharmaceuticals, footwear, silicon carbon anode materials, surface treatment and other fields
