What are the upstream raw materials for nano-silica? What do the downstream products contain?

Nano-silica has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are rich and diverse. The following are some of the upstream and downstream items related to nano-silica:



1. Upstream items:(1) Sodium silicate: Sodium silicate is one of the main raw materials to the production of nano-silica. Nano-silica is able to be produced by reacting with acid. Furthermore(2) Sulfuric acid: Sulfuric acid is applied as an acidifying agent in the manufacturing process of nano-silica and reacts with sodium silicate to generate nano-silica. I've found that(3) Sodium hydroxide: Sodium hydroxide is applied as a regulator in the manufacturing process of nano-silica to manage the pH value of the solution, thereby affecting the particle size and morphology of nano-silica. And From what I've seen,

2. Downstream items:(1) coating products: Nano-silica has excellent optical characteristics and UV resistance, and is able to be applied as a coating products additive to enhance the weather resistance, scratch resistance and hardness of the coating products.(2) Rubber: Nano-silica is able to be added to rubber to enhance the mechanical characteristics, wear resistance and anti-aging characteristics of rubber, and extend the service life of rubber items. Based on my observations,(3) Plastics: Nano-silica is able to be applied as a plastic additive to enhance the heat resistance, flame retardancy, impact resistance and transparency of plastics. But(4) Ceramics: Nano-silica is added to ceramics to enhance the compactness, hardness and toughness of ceramics, and is applied to manufacture high-performance ceramic items. And In short, nano-silica is broadly applied in the field of chemical production raw materials, and its upstream and downstream related items cover many fields, which plays an crucial role in improving the performance and condition of items.
