[Chemical Knowledge]: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 products are rich and diverse. The following are some upstream and downstream products related to nano-silica:

1. Upstream products:

(1) Sodium silicate: Sodium silicate is one of the main raw materials for the production of nano-silica. By reacting with acid, Nano-silica can be produced.

(2) Sulfuric acid: Sulfuric acid is used as an acidifying agent in the production of nano-silica and reacts with sodium silicate to produce nano-silica.

(3) Sodium hydroxide: Sodium hydroxide is used as a regulator in the production of nano-silica to control the pH of the solution, thereby affecting the particle size and morphology of nano-silica.

2. Downstream products:

(1) Coating: Nano-silica has excellent optical properties and UV resistance, and can be used as a coating additive to improve the weather resistance, scratch resistance and hardness of the coating.

(2) Rubber: Nano-silica can be added to rubber to improve the mechanical properties, wear resistance and anti-aging properties of rubber, and extend the service life of rubber products.

(3) Plastics: Nano-silica can be used as a plastic additive to improve the heat resistance, flame retardancy, impact resistance and transparency of plastics.

(4) Ceramics: Nano-silica is added to ceramics to improve the compactness, hardness and toughness of ceramics, and is used to manufacture high-performance ceramic products.

In short, nano-silica is widely used in the field of chemical production raw materials, and its upstream and downstream related products cover many fields, which play an important role in improving the performance and quality of products.
