Is the quality of silica the core of market competition?

Silica is increasingly widely used in various industries as additives, catalyst carriers, petrochemicals, decolorizers, matting agents,

rubber reinforcing agents, plastic fillers, ink thickeners, metal soft polishing agents, insulation and thermal insulation fillers, high-end

daily cosmetics fillers and spray materials, medicine, environmental protection and other fields. And it provides a new material foundation

and technical guarantee for the development of related industrial fields.

1. Specific surface area

The size of silica reinforcing effect mainly depends on its specific surface. Generally, as the specific surface area increases, the strength

indicators of rubber products increase, but the resilience decreases, the tear strength decreases, and it is not wear-resistant. It is difficult to

disperse during mixing, the heat generation is high, the rubber Mooney viscosity is large, and it is easy to burn. Therefore, different formulas

and different uses require different specific surface areas, and the influence of specific surface area on the physical and mechanical properties

of vulcanized rubber is not consistent.

2. Oil absorption value

The oil absorption value reflects the degree of structure. The larger the oil absorption value, the smaller the structure. The tensile strength of the

vulcanized rubber is generally larger, the tensile strength and hardness are larger, especially the wear resistance is smaller, but the elongation is lower.

3. 900℃ burning loss

It shows that when there are too many surface hydroxyl groups, it is easy to cause the structuring of the rubber composite material, making the material brittle.

It affects the processing performance, and the vulcanized rubber is easy to fall off. The surface hydroxyl groups have a strong adsorption effect on the

vulcanization accelerator, which prolongs the vulcanization time.

4. 105℃ heating loss

It reflects the amount of free water in the particle gap. When it is too little, the rubber compound has a high degree of structuring and it becomes difficult to

refine the rubber. If the heating loss is zero, the silica is useless. It is generally more appropriate to control it at about 6%.

5. PH value

Generally around 7, the pH value increases (the acidity decreases), and the vulcanization speed of the rubber compound accelerates.

6. Soluble salt

 

The less the better, but the less, the higher the cost.

 

Why silica dioxide is used in leather coating?

High purity silica dioxide powder is a widely used material in leather coatings, as it provides excellent properties such as 

improved durability, scratch resistance, and water repellency. The powder is made up of tiny particles that are highly 

porous and have a large surface area, which allows them to absorb and retain moisture, oils, and other substances.

In leather coatings, high purity silica dioxide powder is typically used as a Matting Agent, which helps to reduce the 

glossiness of the coating and provide a more natural, matte finish. It can also be used as a thickener, to improve the 

viscosity and consistency of the coating.

The powder is typically added to the coating formulation during the manufacturing process, and is carefully dispersed to ensure 

that it is evenly distributed throughout the coating. It is important to use high purity silica dioxide powder in leather coatings, as 

impurities can affect the performance of the coating and lead to defects such as cracking and peeling.

Overall, high purity silica dioxide powder is an essential ingredient in leather coatings, providing improved performance and 

aesthetics to the finished product.
