As a cement concrete admixture commonly used in construction and other engineering industries, micro-silica powder is mainly silica dust formed by the rapid oxidation and condensation of a large number of volatile silicon monoxide gas and air produced in the smelting process. Its chemical composition in addition to silica, there are many other iron oxides, etc., in order to make it work better on cement concrete. Basically, micro-silicon powder purification, but in addition to purification, we often can also hear encryption, or semi-encrypted micro-silicon powder, which means to increase the density, so what is the reason for micro-silicon powder encryption?

1. Reduce transportation costs

One of the reasons for micro-silica powder encryption is to reduce transportation costs, its physical properties are finer particles of easily dispersed dust, it is easy to produce a large amount of dust phenomenon in actual production, and it is difficult to capture, usually the use of bag dust collector will be dispersed micro-silica powder collection, since this is the case, in the transportation process will also appear the phenomenon of scattering. Then the encryption can effectively solve the problem of drifting, thereby reducing the loss of products during transportation; Moreover, the encrypted micro-silicon powder is much smaller than the unencrypted micro-silicon powder under the same weight, so the same package can carry more micro-silicon powder, thus reducing packaging and transportation costs.

2, improve the performance

As the requirements of cement concrete projects become higher, the requirements for admixtures also become higher, and the characteristics of encrypted micro-silicon powder can just meet the needs. The encrypted micro-silica powder can ensure its fluidity while being more convenient for mixing, which can make the mixing of concrete more uniform, and better enable each kind of admixture to be filled in the molecular structure of concrete, thus increasing the performance of concrete.

3, improve the use of the environment

In the past, in the concrete mixing site, the dust situation is very serious, the reason is that in addition to cement lime powder and other easy to fly, including micro silica powder and other concrete admixtures flying, causing air pollution, but also seriously affect the physical and mental health of the staff, will also cause losses to consumers to a certain extent, and the encrypted micro silica powder particles become coarse, The dispersion is weakened, which can effectively prevent the dust phenomenon and improve the indoor and outdoor working environment.
