High Alumina Ceramic Rollers

Q: What are the production methods of calcium silicate board material?: The two reaction method (also called combined method) is the most complete and easy to obtain process of high temperature, light weight and high strength calcium silicate products and calcium silicate boards, but its disadvantages are long process, high energy consumption and large investment.

Q: What is the maximum temperature at which the glass is cured?: The softening point of quartz glass is 1600 degrees, it is sodium phosphate and phosphate. Gas burner 1300 degrees, after homogenization processing, after annealing treatment of glass products.

Q: What is the difference between calcium silicate board and cement fiber board?: The common point between fiber cement pressure plate and calcium silicate board1, both of the raw materials are similar in composition, both contain silica fume, calcium and fiber.2. Both are processed by pulping and molding.3, the appearance, shape and length and width of the two specifications are basically the same.4, there are many overlapping areas in the scope of use, such as internal and external walls.

Q: What heat preservation material is used for thermal insulation of steam pipe in power plant? How thick is the bag? Please advise!: Steam pipe in power plant thermal insulation rock wool board thickness, according to the temperature in the pipeline to choose, the higher the temperature insulation thickness is generally 80 to 150 mm.

Q: Calcium silicate board white ICI belongs to wood surface paint?: ICI can generally be considered as wall paint (latex paint), and latex paint can be used on this kind of cement board. And lumber is different, it is not suitable to brush latex paint on the surface of wood, it can only be decorated with paint (oil paint).

Q: What is the best price for the use of calcium silicate ceiling?: The price of each place and labor costs are not the same, here in Heilongjiang labor costs about 18---20 yuan per square meter, plus keel, hanger, calcium silicate board of about 45----50 yuan per square meter.

Q: What's the use of low carbon steel insulated nail hooks for power plants?: Low carbon steel nail insulation (aka: insulation pins) material: low carbon steel wire for power plants or stainless steel wire products: insulation nail. Hook nail is a power plant by mechanical processing of special insulation nail models: nail diameter: 3 mm with 3.5mm with 4 mm with 5 mm with 6 mm etc.

Q: What is the main role of fly ash added in concrete products?: The rational use of fly ash in concrete, not only can replace part of cement, reduce the construction cost, but also because of its unique properties can be effectively used for the various requirements of the use of concrete, improve and enhance the performance of concrete.

Q: Eterpan with calcium silicate is sold on the market are the same thing? Non asbestos calcium silicate board is Eterpan it: Aitken is a brand of non asbestos calcium silicate board is a product name

Q: What is a building energy-saving materials?: As far as its varieties are concerned, the new wall materials mainly include bricks, blocks and slabs, such as clay hollow bricks, waste clay bricks, non clay bricks, building blocks, aerated concrete, light plates and composite boards.
