Characteristics of a refractory mineral neutral, neutral refractory structure, chemical composition neutral refractories (Sericite) is a natural fine brick refractories, is a subspecies of the refractory brick agent, is a layered structure silicate, silicon-oxygen tetrahedron structure consists of two layers of silicon oxide layer, double layer of aluminum sandwiched formed octahedral. Cleavage completely, can be split into very thin sheets, film thickness up to 1u below (theoretically be whittled 0.001u), radius to thickness ratio; compared with brick: natural small size has easy processing of ultrafine characteristics. Neutral refractories crystal chemical formula:? K0.5-1 (Al, Fe, Mg) 2 (SiAl) 4O10 (OH) 2 nH2O refractory species, general chemical composition: SiO2 43.13 ~ 49.04%, Al2O3 27.93 ~ 37.44% , K2O + Na2O 9 ~ 11% refractory brand, H2O 4.13 ~ 6.12%. Achieve automotive lightweight aluminum alloy material [China] Aluminum net saving, environmental protection, safety, comfort, intelligence and network development trends in automotive technology, especially energy-saving and environmental protection is a major issue related to sustainable human development. Therefore, reducing fuel consumption and reduce CO2 discharged into the atmosphere and harmful gases and particles has become a major research topic in the automotive world. Reduce the quality of the car itself (car lighter) is one of the most effective measures to reduce fuel consumption and reduce automobile emissions. Automotive lightweight approach in two ways: First, optimize the car frame structure; the other is the use of lightweight materials in the body manufacturing. The most commonly used material for lightweight aluminum. Refractories offer, shangzhuang Refractories (certified), Hebei refractories by shangzhuang Refractories Co., Ltd., Zhengzhou City.
