Take you to understand the industrial silica powder in the mortar action mechanism
The metallic silicon powder can fill the pores between the cement mortar particles, form a gel with the hydration products, and react with the basic data magnesium oxide to form a gel. The following effects can be achieved by adding an appropriate amount of industrial silicon metal powder into the cement mortar:
1. Improve the function of compression resistance, bending resistance, permeability resistance, corrosion resistance, impact resistance, wear resistance and so on.
2. It has the function of retaining water, avoiding segregation and bleeding, and reducing the concrete pumping resistance.
3. Prolong the service life of concrete obviously. Especially in chloride pollution corrosion, sulfate corrosion, high humidity and other harsh environment, concrete durability can be doubled or even several times.
4, useful to avoid mortar alkali aggregate reaction.
5. It has a strong volcanic ash effect. When mortar is mixed, it can react with cement hydration product Ca(OH)2 to form cementification product, fill the layout of cement stone, improve the microstructure layout of slurry, and improve the mechanical function and durability of hardened body.
6. Industrial silicon metal powder is amorphous spherical particles, can improve the activity of mortar function.
7. The uniform particle size of industrial silicon powder is relatively small and has a good filling effect. It can be filled between the open Spaces of cement mortar particles, so as to improve the strength and durability of concrete.
What is the production method of silica powder? There are many production methods for industrial silicon powders produced from silicon blocks. The more suitable is: ball mill method, roller mill method, punch and spin method, the main equipment: ball mill, roller mill, punch and spin machine in the powder quality skill requirements are different. The former is crushed by gravity extrusion and grinding, while the latter is crushed by impact. For non-flammable and explosive ore body with Mohs hardness lower than 7.0, all kinds of mills can process and destroy it. Industrial silicon powder product size by skill adjustment, control in 30 mesh (0.613 mm) to 425 mesh (0.033 mm) between.
