1. Reduce transportation costs
We all know that micro-silica powder is silica ash, which is a by-product of smelting metal silicon and iron silicon, also known as active silica powder. Micro-silicon powder is collected by environmental protection equipment, its initial density is only 150-200 kg/m3, which costs a lot of money in transportation costs, such as unencrypted micro-silicon powder a 60-ton train can only be loaded with about 18 tons, and the transportation cost per ton of micro-silicon powder is sometimes as high as 50% of the selling price. Encrypted microsilica powder is a way to reduce costs. In order to reduce the transportation cost of micro-silicon powder, many micro-silicon powder manufacturers now use encryption technology. For example, manufacturers in Canada, Sweden, the United States, Norway and other countries are supplying encrypted micro-silica powder to commercial concrete companies or concrete micro-silica powder mixing stations. The transportation cost is lower, the loading and unloading is not ash and convenient, and the working environment is good. Easy to pump, high degree of mechanization.
2. Enhance concrete performance
After the micro-silica powder is encrypted, it is convenient for mixing concrete without affecting the fluidity of micro-silica powder. In the concrete production process, the use of encrypted micro-silica powder is more conducive to mixing uniformity and improving the comprehensive performance of concrete, so the application of encrypted micro-silica powder in concrete and other building materials is more and more extensive. Unencrypted micro-silica powder is mainly used in refractory materials or coatings and other fields.
3, improve the production environment
Micro-silicon powder encryption technology was originally only a few developed countries, these countries will sell complete sets of equipment to China, the price is very high. At present, China's technical personnel through scientific and technological research and testing, but also produced the same effect of equipment, the actual operation effect is good. Due to the realization of localization, the cost has been greatly reduced, so that the technology is widely used. After encryption, the microsilica powder is spherical, and the packing density increases from 0.2t /m3 to 0.3-0.6t /m3. This can reduce packaging and transportation costs by about 30 to 60 percent. The loading and unloading efficiency of encrypted micro-silica powder is greatly improved, the storage space and footprint are reduced, which is suitable for automated production, and the fly ash phenomenon is no longer present in the on-site charging, thus improving the working conditions and environment of concrete.
