Green Silicon Carbide with High Purity SiC and Low Price

Q: Refractory material, refractory brick: High alumina brick is commonly used in high aluminum, LZ-75, LZ-65 and LZ-55, as well as high alumina brick for blast furnace, high alumina brick for hot blast furnace, and low creep high alumina brick

Q: What is unshaped refractory?: Plastic. From the production method, the plastic is between the concrete and the castable. It is made of refractory material by refractory material plant, which is made of plastic clay. The ingredient is a retarder. It is packaged by plastic bag, and construction and heat treatment are carried out on the spot. But the biggest problem is the application of plastic on the knotted Jiecha easy peeling, retarder dosage improper or is vulnerable to bad caking plastic hardening.

Q: What are the requirements of refractory temperature of refractory brick?: Refractory bricks furnace pipe material is generally divided into two types, namely, shapeless refractory material and shaped refractory. Shapeless refractory material, also known as castable refractory, is hybrid powder material made up of many kinds of aggregate or aggregate and a kind of or many kinds of binders. It must cooperate and evenly stir with a kind or many kinds of liquids during use and has strong mobility. Shaped refractory material usually refers to refractory brick whose shape has standard rules. It can also be processed temporarily during cutting according to requirement. Refractory brick, called refractory brick for short, is refractory material made by firing refractory clay or other refractory raw materials. Faint yellow or brownish, it is mainly used in building smelting furnace. It can resist 1,580 ℃-1,770 ℃ high temperature.

Q: What characteristics do A grade external wall fireproofing material have?: 1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.

Q: what are the requirements of fireproofing material?: answer: 1 fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc. 2, fireproof?panel is the most common texture in the market. There are two common types: One is the high pressure decorating refractory slab, it's advantages are fireproofing,moisture-proof, wear-resistant, oil resistant, easy to clean, and it has various colors; another one is glass magnesium fireproof board, external layer is decoration materials, and inner layer is mineral magnesium fireproofing material, and it can endure 1500 degrees high temperature but has bad decoration. Installing fireproof suspended?ceiling in outlet channel of construction, stairwell and corridor can ensure safe evacuation of people and protect people from attacking of fire spreading in the disaster. 3, the production process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.

Q: What antioxidant will be used in refractories?: Specifically speaking, it is an antioxidant used in carbon refractory products, which belongs to the fire resistant technology. A kind of refractory used antioxidants, formula proportion is as follows calculated by weight percentage: aluminium zinc alloy 1 ~ 100, conventional antioxidants in 0 ~ 100. Described in the aluminum zinc alloy element of aluminum content is 3% ~ 3%, the rest is zinc. Described aluminium zinc alloy is powder or fibrous long; The biggest size and long fiber powder makeup of maximum diameter is 0.2 mm. Preparation of the present invention contains aluminum zinc alloy antioxidants can prevent carbon oxidation temperature range is big, less side effects, and can adjust the thermal expansion of refractory. Hope I can help you.

Q: The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide: 1. corundum is the main component of alumina. 2. agate is the main component of silica. 3. is right. 4. glass is silicate. 5. solar cells are made from monocrystalline silicon. So 3.5 correct, choose D.

Q: How to choose construction external wall thermal insulation and fireproofing materials?: The width of fireproof partition shuld be greater than 30CM, and the thickness should be the same as total thickness of thermal insulation materials. Fire barrier zone thermal insulation board and base wall should be stuck in whole area. Fire Barrier zone thermal insulation board should be stuck with the assistance of anchor bolt which must press the mesh of the bottom layer. Fire Barrier zone should be set above the door and window, with a distance of less than 50cm between the lower edge of fire barrier zone and the upper edge of window.

Q: can slag tailings be used to be the base materials of refractory materials ?: perhaps not, because it has many pores.

Q: Who knows the texture of fire-proof wooden door material?: Steel door, wooden door or steel wooden door can be inset fireproof laminboard, such as rock wool, perlite. Perlite (fireproof doors filling material, fireproof doors raw material) using for fireproof door core is mainly used for the filling material of fireproof doors and security doors. Fire protection, thermal insulation, good sound insulation effects, and higher performance than aluminum?silicate?wool and rock wool. The combustion performance of perlite using for fireproof door core reaches class A non-combustion, which is new type of fireproof doors filling material with characteristics of low cost, good fireproof performance and excellent environmental protection performance. The advantages of fireproof door core perlite as fireproof door filling material: 1, Good fireproof performance, so it has a function of fire prevention. Environmental protection: all materials are environmentally friendly products. Pollution-free: the product is composed of glass fiber reinforced materials and inorganic binder. 2, with characteristics of non-flammable, non-explosive, water-resistant, oil-resistant, chemical erosion resistant, non-toxic and good mechanical strength, etc. The product can be used for mechanic processing like sawing, drilling, gouging, etc. High fire resistance, in the simulated combustion tests, it doesn't deform when the flame temperature reaching 800 degrees, has good fire retardant and fire-resistant properties. 3, product material is cheap, suitable for all kinds of fireproof materials. Perlite fireproof board is made by pressing the expanded perlite powder and high temperature fireproof adhesive through mould, suitable for the filling material of fireproof wooden door and fireproof steel door, which is the substitute products of aluminum?silicate?wool and rock wool. 4, has advantages of light volume-weight, high refractoriness, strong compressive strength, small thermal conductivity, non-flammable, non-toxic, tasteless, non-pollution, etc.
