how does microsilica become preservable-pg电玩城

microsilica(officially known as "silica fume", or microsilica or silica fume) is the industrial dust dust collected by specially designed dust collector, namely amorphous, powdered sio2, when silicon iron or industrial silicon is smelted, after the silicon steam is oxidized through the flue.

in cement-based products, polymer modification (such as acrylic reinforcement) can effectively improve its performance. acrylic reinforcement is a synthetic resin with methyl methacrylate as the main raw material, which is specially used to improve the physical properties of silicate cement, mortar and cement-based waterproof materials. in acrylic emulsion and powder with uniform mixing, cement absorb the excess water in the emulsion, the emulsion is formed in slurry mesh flexible structure, and the slurry to form interpenetrating network structure of waterproof coating, forming a continuous elastic and plastic film, can greatly improve the corrosion resistance of concrete, friction resistance and freeze resistance ability.

because of microsilica, polymer particles and amorphous hydrated calcium silicate, etc. the small size of particles, makes the coating and coating on the surface of the micro combined with distance shortened greatly, thus greatly improve the bonding strength of coating and structure (8 mpa), in meet can effectively waterproof surface and back surface, improve the ability of toughness and crack resistance of cement mortar, after the hardening of the waterproof layer, can also have the function of normal mortar strength, but also because of its excellent waterproof impermeability and crack resistance, and is widely used in all kinds of buildings (the ground construction, hydraulic engineering and underground engineering, etc.) and waterproof impermeability and crack resistance of concrete products and maintenance cheng.

thickening the protective layer of steel. the protective thickness of the corroded underground part should be 5-15mm larger than the design to resist the external erosion for a long time.

the exterior of the structure is covered with a brush:

coating antisepsis. coating the surface of grouting material structure with anticorrosive coating. the commonly used coating is chlorosulfonated polyethylene acid-base coating. asphalt paint, epoxy coating, coal tar and other anticorrosive materials.
