Q: What is the difference between white carbon black and carbon black?: Carbon black is the floorboard of white powder X- ray of amorphous silica and silicate products, mainly refers to the precipitated silica, fumed silica, ultrafine silica gel and gel, including powder synthetic aluminium silicate and calcium silicate etc.. Silica is a porous substance whose composition can be represented by SiO2 nH2O, where nH2O exists as a surface hydroxyl group. Soluble in caustic and hydrofluoric acid, insoluble in water, solvent and acid (except hydrofluoric acid). High temperature, non flammable, tasteless, odorless, and good electrical insulation.

Q: What are the states of silicon dioxide?: Silica widely exists in nature and forms rocks with other minerals. Natural silica, which is about 12% of the earth's crust, is composed of two kinds of crystalline and indefinite forms. Quartz crystals are crystalline silica with different crystalline shapes and colors.

Q: Does the dust produced in the manufacture of abrasive wheels contain silica?: 3, mask materials are silicone, plastic and so on, silicone material is relatively soft and comfortable, low facial pressure.4, for dust and oily particles, masks are divided into anti oil (soot, oil mist, dust, smoke, fog, micro-organisms, expressed in KP), dust (dust, smoke, fog, micro-organisms). For dust prevention, the protection level has KN100, KN95 and KN90 three grades, because this work environment pollutant diversity, harm to people more, I suggest the choice of KN100 grade.

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: 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: Lead-acid battery plate production and paste adding silica have what use?: Improve the conductivity of active substances and improve the porosity of active substances, adsorption of excess surface material, improve the ability to charge acceptance

Q: What materials do you have instead of silica powder?: According to the guide light transmittance is divided into several. The most typical is silica, but the brightness of the silica has not been ideal for addition to the resin. There are many developed new conductive powder, haze higher, higher brightness. Better than silica.

Q: What are the roles of silicon and silicon dioxide?: Silicon material is the most important semi conductive material at present. At present, the world's annual output is about 3 * 106kg. A diameter of 75mm silicon chip, can be integrated tens of thousands to hundreds of thousands or even millions of components, forming a micro electronics, thus the emergence of microcomputers, microprocessors and so on. Because of the development of current information engineering, silicon is mainly used in micro electronics technology. Tube power semiconductor device based on thyristor element, bigger and bigger, compared with silicon transistor integrated circuit on the contrary, silicon chip with the diameter of 75mm, only a few kA can withstand the current and voltage of several kV components, the components into electronics, power and control field is 3 the formation of a new discipline - power electronics.

Q: What is the raw material of nanometer silicon dioxide?: It depends on what kind of production method, meteorological method is the main raw material of four silicon chloride or trichlorosilane, precipitation is the main raw material of sulfuric acid and sodium silicate or quartz sand.

Q: How to solve the gel problem between silicone oil and white carbon?: Two substances entirely. Some aspects can be substituted.Carbon black is the hydrocarbon gas in the process of strict control of incomplete combustion or pyrolysis of a black powder.
