Silica is a base adsorption material, an amorphous substance, with a chemical formula of mSiO2·nH2O. It is insoluble in water and
any organic solvents, non-toxic and odorless, with stable physical properties, and does not react with any substances except strong
acid and hydrochloric acid.
Drying is to evaporate the water in the rubber ball particles and shrink the volume under the action of liquid surface pressure, so
that the primary particles can be "grow" again to achieve the purpose of deep aging. In order to better inhibit the degree of aging,
silica manufacturers often achieve it by controlling the acid content in the rubber ball during drying. In practice, large and small pore
rubbers are mostly dried at normal high temperature conditions. The higher the drying temperature, the faster the primary particle
aggregation speed and the larger the diameter. This is the principle of baking drilling. In order to produce silica gel with small pore
shrinkage and even no shrinkage, the method of reducing the liquid surface pressure is often used to achieve it.
The relationship between the quality parameters of finished rubber and the processing characteristics of silica gel The processing
characteristics of silica gel determine the quality parameters of finished rubber, and conversely, the quality parameters of finished rubber
require certain processing characteristics.
Now we take the bulk density of finished rubber as an example to analyze the relationship between the two. Bulk density is one of the
key quality parameters in the analysis of silica gel products, which can intuitively and simply reflect the physical parameters of the internal
pore structure of silica gel particles.
Under the same conditions, for silica gel with a certain pore volume, corresponding to a certain bulk density, the diameter and pore volume
of the two types of rubber A, T3, and C increase successively, while Vu} decreases successively. This is the basis for the bulk density to distinguish
the two types of rubber A, T3, and C. Even if it is the same type of rubber, the size of the bulk density will roughly determine the internal pore
structure of the silica gel particles.
When silica matting agent is called as high purity silica matting agent usually has 99.9% content. High purity silica matting agent is one of the
curcial parts in elastic coating formulation. It is used as filler in elastic coating. It can provide and enhance the technical ability. Matte elastic
coating is special coating that means it stretch and return to their original shape without cracking or breaking.Silicon dioxide can help to enhance
the elastic ability and flexibility of coating which allow it to stretch and conform to different surfaces without losing its integrity. Besides its technical
ability, high purity silicon dioxide can also provides other advantages like it can decrease the glossy of coating to achieve the matte effect. This
appears as scattering and diffusing light,resulting in a non-reflective surface.
High purity silicon dioxide has chemical stability and excellent high temperature stability. It will not easy to react with other elements in enviroment
which can promise the using time and durability of coating. Depending on its high temperature stability makes the elastic coating prevent the situations
from discoloration under high temperature.
Overall, high purity silicon dioxide is the keypoint of producing matte elastic coating. Its high purity, excellent technial properties, matte effect
ability and chemical stability can make it as an ideal choice.
