In addition to rubber industry, in which fields can silica be used

We all know that silica is mainly used in silicone rubber products and other manufacturers. Silica gel and rubber products in the production process, will consume a lot of silica, its market is still relatively large. However, silica can not only be used in the processing of silicone rubber products, but also can be well used in the new energy and construction industry, and has achieved certain results. So, in which specific products can be used silica? Carbon black manufacturers to share with you four products.

Special precipitated silica for battery separator

According to reports, European amosil company produces high-quality microporous PVC / silica separator for high-performance lead-acid batteries. This kind of separator is especially suitable for colloidal batteries and various types of power, long-life and high specific energy battery applications.

China is a big country of battery production and use. There should be a great demand for special precipitated silica for battery separator in the future.

Special precipitated silica for thermal insulation materials

Thermal insulation material refers to the material with thermal conductivity lower than 0.175wm-1k-1. The special precipitated silica used in thermal insulation materials has larger specific surface area, higher porosity and lower density. As early as 1987, Ge applied for a patent for the application of precipitated silica and applied it to the insulation materials of household refrigerators and refrigerators. In recent years, a number of domestic research institutions have carried out relevant research, mainly on the synthesis technology and application technology of this kind of silica.

Precipitated silica for papermaking

In Japan, Sweden and other countries, high dispersion precipitated silica is used as a good additive for papermaking. Highly dispersed precipitated silica is a kind of porous material, which is full of small holes. The alkanol group on the surface can form hydrogen bond with the hydroxyl group on the surface of pulp fiber. When drying, silica and pulp fiber are firmly combined, which can improve the strength of paper products. Moreover, the porous property of high dispersion precipitation silica helps to absorb a large amount of ink and prevent through printing Use.

It can be seen that high dispersion precipitation silica is one of the essential functional auxiliaries in newsprint lightweight, which can not be replaced by other fillers. In addition, it is unnecessary to dry silica with high dispersion precipitation method. When used, it can be mixed with pulp and then dried together with paper, which can save the energy needed for silica drying and reduce the cost.

Preparation of precipitated silica from various nonmetallic minerals

The technology of preparing precipitated silica from nonmetallic minerals refers to the preparation of precipitated silica by a series of chemical synthesis processes using cheap nonmetallic minerals as silicon source. The key technology is to transform crystalline silica and silicate into amorphous silica.

The main raw materials are wollastonite, opal, halloysite, olivine, ophiolite, kaolin, hard kaolin, coal gangue, fly ash, etc.

Silica for the production of products, not only these four, there are many other products can use silica to play a role in coloring, filler. It plays a completely different role in different industries. In many processing industries, it is a good additive. If necessary, you can contact the staff of our White carbon black manufacturer.
