What are the applications of neutral silica sol?

A neutral hydrosol is a colloidal solution in which polymeric silica particles are dispersed i water. It is a silica sol with a pH between 4 and 8.5.

Neutral silica sol has a large specific surface area, adsorption, good adhesion, high

temperature resistance, water resistance, skid resistance, etc. ), and good dispersion, no pollution. Therefore, its application in various fields has a special and important position.

It can be widely used in textiles, electronics, refractory materials, solid batteries, food,

synthetic resins, metal surface treatment, inorganic architectural coatings, agricultural fertilizers and other fields.

1. Application in refractory fiber materials

Due to the low sodium content in neutral silica sol, it can withstand higher temperatures,so

it can be used in the binder of refractory fiber materials and has higher electrical resistance.

2. Applied to electrostatic flocking technology

Neutral silica sol is used in electrostatic flocking technology because it forms silanol groups

on the surface of fibers, making fibers hydrophilic and improving the electrification of flocking wool. It is the main component of the electrostatic flocking fluff treatment agent

and plays a dispersing role.

3. Create clarifiers in food

Adding neutral silicon solution to the solution after beer fermentation can make impureions form condensate and be removed, making the product clear and transparent. It can also be

used as a clarifying agent for rice wine, soy sauce, fruit juice, etc. , without affecting the color, aroma and taste of the product. Silicon is harmless to the human body.

4. It is suitable for color picture tube

Neutral silica sol is used in the manufacture of color picture tubes and fluorescent screens. Due to its good dispersibility and adhesion, it can be used as a dispersant for color picture

tubes and fluorescent screens.

5. Application of colloidal lead-acid batteries

When neutral silica sol is used in colloidal leadacid batteries, the silica gel produced by mixing with sulfuric acid is an ideal non-flowing electrolyte for colloidal lead-acid batteries. It overcomes the shortcomings of traditional lead-acid batteries such as acid leakage, environmental pollution, heavy acid addition, water addition, maintenance and operation. It also prolongs the service life of the battery, hasgood lowtemperature starting performance, impact resistance, onetime filling, and is safe and reliable.
