In the 20 years of the birth of Youmingke Fan Machinery, it has always adhered to the scientific management model of modern enterprises, insisted on \u0026 ldquo; piety, fine, strict, harmonious \u0026 rdquo; at the same time, pursuing excellence, casting a dawn brand, revitalizing National Industry \u0026 RDQUO; as an unswerving development purpose.
The chemical formula of the silicon dioxide is SIO2. Silicon dioxide has two forms: crystal state and non -fondable. Silicon and quartz sand in nature, such as silica and quartz sand in nature. Pure quartz is a colorless crystal. The large and transparent prism -shaped quartz crystal is called crystal. It contains trace impurities and is purple. Chaylosis, agate and jasper are all non -ferrous quartz crystals containing impurities. Sand is a quartz with impurities. The protein stones and diatoms are non -fonding silica. Silicon dioxide is widely used. It is mainly used for glass, water glass, pottery, enamel, refractory material, gas gel felt, silicon iron, type sand, single silicon, cement, etc. In ancient times, silicon dioxide was also used to make porcelain in ancient times. Glaze and carcass. General stones are mainly composed of silicon dioxide and calcium carbonate. The melting point of crystalline silica is 1723 ° C, and the boiling point is 2230 ° C, which is insoluble in water. Except for fluoride gas and hydrofluoric acid, silica is not reacting with halogen, halide hydrogen and inorganic acid, but can be dissolved in hot alkali, melting strong alkali or sodium carbonate. In addition, silicon dioxide can be restored by coke, magnesium, etc. at high temperature. At normal temperature, strong alkali solution and SIO2 will slowly react to generate silicate, so the glass bottle that stores strong alkali solution cannot be stuffed with grinding glass (containing SiO2 in the glass), otherwise it will generate viscous sodium silicate NA2SIO3 to make the bottle make the bottle The mouth and the bottle mouth are bonded together. Because SIO2 can react with hydrofluoric acid, hydrofluoric acid cannot be placed with glass containers.
Cases of Calcium Carbonate Machine in Youmingke: This customer is a stone powder company in Haicheng, mainly operating calcium carbonate powder, magnesium oxide, magnesium powder, magnesium ore raw ore For companies that are produced and processed by products, the company needs to classify calcium carbonate ultra -micro powder, and graded products required for granularity segments. After expected experiments and output demand, the ITC450 host of Our Famous Fan Machinery can meet the company's demand, and finally purchased multiple vertical airflow grading machines of our company. Various major calcium carbonate powder manufacturers with powder grading are welcome to visit the factory to visit and materials. How much is the sorting instrument of calcium grinding calcium carbonate particles
