High Alumina Textile Ceramic Rollers

Q: What's the difference between white carbon and carbon black? Can they be replaced?: White carbon black in color rubber products instead of carbon black reinforcing, meet the needs of the white or translucent product. Anti aging performance of silica with strong adhesion force, tearing resistance and heat, so the black rubber products can replace part of the carbon black, in order to obtain high quality rubber products, such as off-road tires, engineering tire, radial tire.

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?: No, it isn't。Calcium silicate board material properties should be comparable with cement products, usually referred to as cement board is actually calcium silicate board.

Q: Cement is not silicate products: There are different kinds of cement: silicate series, aluminate series, sulphoaluminate series, sulfur ferrite system, etc.

Q: Why is calcium silicate board unsuitable for use in home improvement?: Because the silica plate contains quartz composition, and the content is still higher. Quartz is a carcinogenic substance, the long-term impact of this substance, the human carcinogenic probability will be greatly enhanced

Q: Eterpan and yinte in what is the difference?: Eterpan:Eterpan, is a kind of fiber reinforced silicate plate (fiber cement board), the main raw material is cement, plant fiber and minerals, the flow of high temperature steam pressure and slurry method, mainly used as building materials.Eterpan is a kind of high strength, durability and other advantages of fiber silicate sheet, with various thickness and density, 100% does not contain asbestos and other harmful substances. For non combustible A1 grade products.The utility model has the advantages of fire prevention, moisture proof, waterproof, sound insulation effect, environmental protection, quick installation, long service life, etc.. Often used for wall panels, bathroom partitions, outdoor roofing, roofing, exterior insulation panels, interior decoration, ceilings, etc.; alsoInstead of gypsum board, used as base material in decoration.

Q: What are the raw materials of cement products? What's the function?: Sand。 Gravel occupies a very large volume in concrete production, reaching 70%~80%. The aggregate surface, structure, adsorption and water content of aggregate should be required. The appropriate amount of sand and gravel can save cement, reduce the cost of concrete production, and improve the strength of concrete.

Q: What's the difference between white cement and ordinary cement?: The main chemical composition of Portland cement clinker is calcium oxide, silica, alumina and iron oxide. Calcium oxide mainly derived from calcareous raw materials, such as limestone, chalk, marl; alumina and silica from aluminum silicate containing substances, such as clay, blast furnace slag and fly ash; iron oxide is used in sulfuric acid production of sulfur iron slag. For the content of calcium oxide production of Portland cement lime materials in 52%; silicon oxide content of clay in raw materials up to about 57%, the alumina content is less than 20%. In order to reduce the calcination temperature and to produce part of the melt during calcination, a small amount of iron oxide is often added. Of raw materials but also control the content of alkali and Magnesium Oxide, Magnesium Oxide is content in the cement clinker should be less than 5%, total alkalinity (Na2O+K2O) for general cement should be less than 1.2% of low alkali cement should be less than 0.6%.

Q: Eterpan with calcium silicate is sold on the market are the same thing? Non asbestos calcium silicate board is Eterpan it: Eterpan is calcium silicate board there is a famous brand. Non asbestos calcium silicate board has many kinds, Aitken is just one.

Q: How to make building glue?: The invention relates to an architectural adhesive, which is characterized in that the composition of the building glue comprises 28-50wt% sodium silicate water solution, 34-53wt% quartz sand and 8-35wt% magnesium silicate.Adhesive for a building, it is the following: the weight ratio of 4 to 6, PVA cellulose 6 - 12, 1 - 2, copolymer admixture from 0.01 to 0.05, according to the proportion of polyvinyl alcohol with hot water first fully dissolved, then adding cellulose, copolymer, admixture and stir evenly. The glue can be combined with Portland cement or construction gypsum to cement all kinds of light plates. This product is non-toxic and tasteless, harmless to the human body, is a wide range of uses, superior technical performance of environmentally friendly building adhesive.
