Caustic calcite magnesite is made from nature magnesite through calcining in reverberatory furnace,rotary furance and boiling furnace.This products calcine uniform possess stable quality,high purity and well-activeness, are used widely in paper making, chemical industry, production of pharmaceuticals,animal husbandry, rubber making refractory material and buliding material industry etc.

Q: What is the industry standard of graphite powder coating for casting?: The two is fine, the finer the better, generally with the "eye" as a unit, that is, sieve stone toner used in the screen, square inch area included in the number of holes, the larger the number the better.

Q: Graphite powder what is the difference?: Lead chemical symbol Pb, belonging to heavy metals, toxic to the human body, excessive intake of lead will accumulate in the body, the body can not take the initiative to discharge, a great harm.

Q: Is graphite powder dangerous?: Has excellent conductive properties. The color steel gray or gray, with metallic luster, with lubrication, easy dyes, chemical stability, heat conductivity, good heat resistance, acid and alkali resistance, corrosion resistance, oxidation resistance, due to its small crystal plasticity, good adhesion, so it does not belong to dangerous goods!

Q: Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?: At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents;

Q: What mask should be used to prevent stone powder?: As an enterprise employee, we must actively advocate the right of labor protection to the enterprise owner, and the stone powder can be worn with industrial masks

Q: Why should the lubrication of automobile leaf springs be made of graphite grease?: This ultra high temperature grease in high temperature above 200 DEG when the base oil volatilize slowly, will be attached to the graphite solid lubrication lubrication is formed on the surface of graphite, itself is a kind of solid lubricant for heavy load / load impact or damp / high temperature friction parts and bearing lubrication under the pollution of the environment, to provide maximum anti rust corrosion protection

Q: Graphite and graphite in the end is not a matter I would like to know the graphite and graphite: Graphite gum APS two, colloidal or semi - colloidal graphite. (a) colloidal graphite, graphite powder from natural or artificial graphite fine powder in water or other media (e.g., alcohol, mineral oil) colloidal suspensions in the form, and can add a few other products (e.g., tannic acid or ammonia) to be stable. Colloidal graphite is usually semi liquid and is used primarily for lubricating products or for its high electrical conductivity. (two) a semi colloidal graphite (i.e., a colloidal suspension of graphite in water or other medium). Semi crystalline graphite can be used to prepare graphite lubricants or to form graphitized surfaces. This class contains only colloidal or semi colloidal suspensions of graphite with graphite as base material in any medium.

Q: Main ingredients of graphite powder?: In nature there is no pure graphite, which often contains SiO2, Al2O3, FeO, CaO, P2O5, CuO and other impurities.

Q: Why does the temperature rise when the graphite powder is turned on?: The presence of resistance, melting point at 3850 + 50 degrees C, graphite powder is a very sensitive chemical substances, in different circumstances, his resistivity will change, that is, his resistance value will change

Q: What kinds of graphite powder has it? What's the function?: Its main use focuses on sealing and lubrication, and stone toner is powder, is the basis of other graphite products
