Densified Silica Fumes

Q: Where is silica produced?: Silica is the main component of quartz, pure quartz (silica) is crystal; is a mineral, not produced.

Q: What is the difference between white carbon black and carbon black?: Two substances entirely. Some aspects can be substituted.

Q: What are the raw materials for the production of precipitated silica?: Sodium metasilicate solution reacts with dilute sulfuric acid in a special unit to produce sodium metasilicate and sodium metasilicate.

Q: Application characteristics of silicon dioxide shedding agent for shedding agent: After the silica paste is used, the film can improve the "yellow change" phenomenon. The porous structure of silica adsorbs the metal ions, such as iron ions, to oxidize it, thus reducing the possibility of yellowing.

Q: Which component of concrete contains silica?: I say the figures are only about, specific can do a chemical analysis, you want the data can be very simple to do an analysis, routine 8 element analysis, general experimental test structure can do;

Q: What are the differences between micro powders, silica gel and silica?: In the pharmaceutical industry, most of the time, micro powder, silica gel and silica refer to the same thing, which can be interchanged most of the time in practical applications. According to the different preparation process can be divided into gas phase silica (colloidal silica) and silica, silica powder is fumed silica (colloidal silica) refers to the use of gas phase method prepared silica powder; silica is prepared by precipitation of silica gel (actually very fine).

Q: Effect and function of silicon dioxide: The utility model can solve the agglomerate formed by moisture absorption and compression, and has the adsorption function, and is an excellent flow enhancer. For eggs, milk powder, cocoa powder, powdered sugar, vegetable powder, powder, Instant Coffee

Q: The harm of silica powder to the skin: Harmless, the most common is sand. Silica mineral refers to the same chemical formula (SiO), but there are differences in the structure of minerals, these minerals are called as different as the main body, including quartz, cristobalite and tridymite. These minerals are found mainly in granite, sandstone, and black earth on earth. There are two kinds of crystalline silica and amorphous silica in nature.

Q: What's the difference between white carbon and carbon black? Can they be replaced?: 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. Silica is a porous material, its composition by SiO2 nH2O, where nH2O is there the surface hydroxyl form. Soluble in caustic and hydrofluoric acid, insoluble in water, solvent and acid (except hydrofluoric acid). High temperature resistant, non flammable, tasteless, odorless, has the very good electric insulation.

Q: What are the environmental hazards of silica?: Silica dust is very fine, the specific surface area of more than 100m2/g (automatic F-Sorb2400 BET nitrogen adsorption specific surface area tester), can be suspended in the air, if the long-term inhalation of dust containing silica, will suffer from silicosis (formerly known as silicon for silicon, formerly known as silicosis silicosis).
