microsilica and thermal insulation material-pg电玩城

silica fume is widely used in high-grade high-performance refractory castables and prefabricated parts, large iron groove materials and steel-clad materials, permeable bricks, spread materials, self-flowing refractory castables and dry-wet spray, oxide-bonded silicon carbide products, corundum mullite push plates high-temperature wear-resistant materials and products, corundum and ceramic products, in addition to the cement and building materials industry have also been extended to varying degrees. expressed as:

(1) there are many pores in the traditional refractory material, and the micro-silica powder is filled in the pores, which increases the bulk density and reduces the porosity, and the strength can be obviously enhanced.

(2) microsilica powder has strong activity, can form colloidal particles in water, and adding proper amount of dispersing agent can enhance fluidity and improve pouring performance.

(3) micro-silica powder easily forms -si-oh group in water, has strong hydrophilicity and activity, can enhance the coagulation of refractory materials, and at the same time greatly improve the high temperature performance, and can extend the use of refractory products. life.

  as a new raw material, micro-silica powder is widely used in thermal insulation materials. it plays an important role in the improvement of amorphous refractories. and the body performance is as follows:

  1. there are many pores in the traditional refractory material, and the micro-silica powder is filled in the pores, which increases the bulk density and reduces the porosity, and the strength can be obviously enhanced.

  2, microsilica has strong activity, can form colloidal particles in water, adding appropriate amount of dispersant, can enhance fluidity, thereby improving pouring performance.

  3. microsilica easily forms -si-oh group in water, has strong hydrophilicity and activity, can enhance the coagulation of refractory materials, and at the same time greatly improve the high temperature performance, and can prolong the service life of refractory products. .

  microsilica is widely used in the refractory industry. the practical application is as follows: instead of pure aluminum oxide mud as refractory material. the production of amorphous and shaped refractory products as an additive greatly improves the strength and high temperature properties. the casting of the steel drum as a whole is combined with a coagulant. adhesives, binders, accelerators, additives for other refractory products.
