A, for insulation: 1, can reduce the surface temperature of the unshaped refractories, reducing heat loss and save fuel. 2, to ensure safety in production, improve product quality. 3, to prevent deformation of the metal equipment, extend machine life. B, used in petrochemical: ensures constant temperature medium temperature, constant cold, ensure the normal chemical reactions, chemical products to prevent corrosion of equipment and piping. C, for magnesia products: production of magnesia-watt, porous calcium silicate, magnesia twisted rope, magnesia pads, magnesia board, magnesia felt, foam brakes magnesia, magnesia and other key products, is not the lack of high-quality raw materials. D, used in construction: the production of high-level architectural ceilings, can play a heat insulation effect. The walls have acoustic, warehouse towers insulation, cold, frost, etc. have a good practical value. From the above, the magnesia insulation materials is essential in most sectors and a larger amount of supplies. In terms of thermal insulation played a very important role. Practice has proved that the quality of unshaped refractories Which is best to use our products than usual insulation can save energy 25% -40%. In particular about the economic benefits of lower costs, savings, etc. are more substantial than other insulation materials. Second, the physical properties of the neutral refractories 0.670W. (MK) -1 unshaped refractories most famous manufacturers, electrical insulation, 200kv, anti-radiation 5 × 1014 thermal neutrons / cm2 contrast ratio. Another chemically neutral refractory composition, structure, and kaolin similar structure, but also has some of the characteristics of clay minerals, or scattered good suspension, fine grain color white, sticky, etc. in an aqueous medium and organic solvents. Thus, a variety of characteristics of both neutral refractories and refractory clay minerals minerals. Unshaped refractories widest range of manufacturers, Yulin unshaped refractories, Refractories shangzhuang provided by Zhengzhou City shangzhuang Refractories Limited. Zhengzhou City shangzhuang Refractories Co. (www.yntjj.com.cn) (www.yntjj.com.cn) strong, credible, in Zhengzhou, Henan Province of charge, flux and other industries has accumulated a large number of loyal customers.
