High Alumina Textile Ceramic Rollers

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:What's the difference between white carbon and carbon black? Can they be replaced?: Carbon black is the floorboard of white powder X- ray of amorphous silica and silicate products, mainly refers to the precipitated silica, fumed silica, ultrafine silica gel and gel, including powder synthetic aluminium silicate and calcium silicate. Silica is a porous material, its composition by SiO2 nH2O, where nH2O is there the surface hydroxyl form. Soluble in caustic and hydrofluoric acid, insoluble in water, solvent and acid (except hydrofluoric acid). High temperature resistant, non flammable, tasteless, odorless, has the very good electric insulation.

Q:Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?: Aluminum silicate fiber can be divided into many kinds according to the aluminum content, the use temperature range is relatively large, the heat insulation property is good, but the price is more expensive.

Q:What's the use of white portland cement?: White portland cement as the raw meal with the proper components till the partial melting of the calcium silicate as the main ingredient, the iron content in clinker less addition of gypsum, white water ground made of rigid cementitious material. When grinding cement, allow limestone not to exceed 5% of the cement weight. White cement is mostly ornamental, and its manufacturing process is much better than ordinary cement. The gap is mainly used to hook white tiles, is generally not used in the wall, the reason is not high strength. It is available in the building materials market or decoration materials shop.

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 are the raw materials of cement products? What's the function?: Water is necessary for the production of cement products, the role of water is to cement hydration. Generally, the water cement ratio of concrete is 0.40~0.65. If the water is too large, it will leave a hole in the concrete, which will affect the strength, density and durability of the concrete and even cause water leakage.

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's the use of low carbon steel insulated nail hooks for power plants?: Mild steel is a type of carbon steel, and its carbon content is between 0.1% and 0.3%. The so-called carbon steel is also called carbon steel, refers to the carbon content of less than 2.11% of the iron carbon alloy. As we all know, the carbon content of the impact on the iron and carbon alloy is very large, the higher the content, the greater the hardness, but the smaller the toughness, and therefore easy to damage. Low carbon steel, because of its low carbon content, therefore, good toughness, low hardness, easy to carry out a variety of processing, such as welding, forging, etc.. And after some heat treatment, low carbon steel can obtain various properties, such as wear resistance, corrosion resistance and so on.

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:What is a building energy-saving materials?: Mainly include new wall materials, insulation materials, waterproof sealing materials, ceramic materials, new chemical materials, decoration materials and various industrial waste residue comprehensive utilization.
