Microsilica can be used in a variety of cementation products, such as concrete, grouts, and mortars as well as elastomeric, polymer, refractory, ceramic and rubber applications.
We collect micro silica from our own 16 ferro silicon furnaces. Monthly we collect approx. 2000 MT micro silica with Sio2 85-94%

Silicon Dioxide Classification fumed

Q: Silica is not KIA light effect: Can play the role of matt.If the light is relatively high, should choose imported silica matting powder, characteristics of extinction effect is good, the price of your.

Q: Can crystal and SiO2 be equal? Why?The SiO2 name is called crystal, this sentence?: Different. The former is a mixture, the main component is SiO2, and SiO2 is a compound, is pure

Q: How to remove silica from slag: The precipitation separated washed and calcined at a temperature of 950-1200 DEG C, get a alumina powder, the mother liquor can be recycled. In the lattice type alpha alumina, oxygen ion for the six party close packing, Al3+ symmetrically distributed in eight sides surrounded with oxygen ion centers, crystal lattice can be great therefore, melting point, boiling point is high. Alpha alumina insoluble in water and acid, also known as alumina industry, is the basic raw material of aluminum;

Q: Tea tea in the additive silica is what role do harm?: By eating into the body of the additive with silica, alkali, acid and acid environment, cavity environment of weak acid environment on the intestine are not decomposed, does not absorb, finally with the feces discharged together. It is worth noting that the higher value of free silica content in the air (respirable silica dust: the standard of respirable dust collection means the dust in the air dynamics diameter below 7.07 m, and the aerodynamic diameter of 5 mu m dust collection efficiency of 50%. in respirable dust free silica content of more than 10% people called respirable silica dust in the air. The workshop 10%~50% containing free silica respirable silica dust the maximum allowable concentration of 1mg/m3. in the air of workplace with more than 50%~80% of free silica respirable silica dust the maximum allowable concentration of 0.5mg/m3. in the air of workplace containing more than 80% free silica respirable silica dust maximum allowable concentration For 0.3mg/m3.) in this type of work environment, chronic exposure (a few weeks with a weak constitution and a few years of strong constitution) can lead to silicosis

Q: Is silica and white carbon a product?: Silica dioxide belongs to a wide range of products, including many products. Such as white carbon, quartz powder and so on. The products are different according to the different process.

Q: Why is silicon dioxide made up of atoms?: If it is a gas or liquid or a low boiling point solid, it is usually a molecular composition

Q: Application characteristics of silicon dioxide shedding agent for shedding agent: The application of silica in the film when the opening agent added to allow customers to reduce the amount of amide slip agent, also can get excellent opening effect, static / dynamic friction reducing effect is obvious, the effects of additives on silica opening haze increased very little added in the film, the transparent degree is high, can effectively improve the end of yellowing the phenomenon of ".

Q: Is expired colloidal silica available?: In order to recover, the gel must be calcined at high temperature to obtain silica fume and then react with sodium hydroxide solution to filter the silica sol. The sol can also be prepared by dilute solution of water glass, filtering, cation exchange, anion exchange, adjusting pH value and concentrating.

Q: Does the plant absorb the effective silicon in silicon calcium fertilizer or absorb silica?: Silica is not absorbed. Elemental silicon is not directly absorbed by plants

Q: How do you remove all calcium carbonate from silica?: The removal method: because the calcium carbonate reacts with hydrochloric acid to produce gas and solution, silica does not react and does not dissolve, so it is filtered and separatedEquation: CaCO3+2HCL=CaCl2+CO2! +H20!
