General Information

Silicon mortar is adhesive material matched with silica brick. Our silicon mortar has such advantages as high adhesive strength, high refractoriness, excellent refractoriness under load, and good installation performance.

 

Feature

Control the liquid system, Adhesive, Polymer's rheology and thixotropy.
As additive agent used to prevent subside,thickening and prevent sagging.
Reinforce HRC high temperature sulfuration silicon rubber and RTV-2K room temperature sulfuration silicon rubber.
Improve the quality of the powder, and improve the liquidity and anti-blocking characteristic.


Application
paint and coating, Unsaturated polyester resins, laminating resins and gel coat.
HCR high temperature sulfuration silicon rubber and RTV-2K room temperature sulfuration silicon rubber.   Adhesive and fluid sealant, Printing ink, Cable rubber,Plant protection,Food and cosmetics.

Q:Why is the three oxidation of two silicon is very harmful impurities in silica brick
Can generate the material needs is the best way to see the impurity problem!! the first consideration is whether can get the material impurities with what method choice after the time! Miscellaneous reactions cannot have new impurity formation! Selected cannot and need material reaction reagent!
Q:The high thermal conductivity of silica brick and traditional brick what is the difference?
The scale quartz is a spear shaped double crystal structure, very compact and favorable to the increase of thermal conductivity. The high thermal conductivity of silica brick in improving thermal conductivity and other performance indicators and traditional coke silicabrick agreement.That is to say, the high thermal conductivity of silica brick all inherited the traditional advantages of coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity
Q:The hot blast stove when the temperature did not rise against the brick interface decreased
Different insulation methods can be adopted according to the length of the stop time and the location and equipment of the overhaul. Gold, refractory material factory specializing in the production of various specifications of brick
Q:Can not use it two brick
The softening temperature is up to 1640~1670 DEG C, and the volume is stable at high temperature for a long time.
Q:Why in the production of the brick to detect the volume density
Density is the property of material, different density of materials, density of the same kind of material is not up to standard, affecting performance.
Q:The introduction of silica brick
Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.
Q:High temperature refractory material?
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, the refractory material used for special occasions.Now the definition of refractory materials, has not only depends on whether the refractoriness at 1580 DEG. Refers to the current refractories used in metallurgy, petrochemical, cement, ceramics and other production equipment with inorganic non-metallic materials.
Q:Semisilica brick interpretation
High temperature volume stability. Volume change is small.
Q:Such purpose and scope please give me detailed points thank you because I am learning stage
Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
Q:The difference between clay refractory bricks and refractory brick in the application??
Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use,
