Product Description:

Silicon carbide

Products Description

With quartz sand and petroleum coke as its main raw materials, black silicon carbide is produced at high temperature in an electric resistant furnace. Its hardness is between corundum and synthetic diamond and its mechanical strength is higher than corundum, which makes it an ideal material for high quality abrasivetools.                                                                                                                                    


1. The most widely application of silicon carbide is producing abrasive tools, such as grinding wheels, cutting disks, etc. Black silicon carbide powder also could used as lapping and polishing media.

2. Black silicon carbide is suitable for processing glass, ceramics, stone, metal, rubber and other materials. 3. Black carborundum also can be used as metallurgical additive and high-grade SiC refractory material

Q:What's the feature of construction external wall fireproof and thermal inuslation matertial?
It has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Its heat conductivity coefficient at normal temperature is 0.018W / (K · m) . The thermal insulation property is three to eight times that of the traditional materials. And it is completely waterproof. [2] Thermal insulation lining has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Light, generally about10-96kg / m3, 20kg / m3 or less is felt, 24-48kg / m3 is middle-hard plate, 48-96kg / m3 is hard plate, wherein 48kg / m³ can be used as ceiling, with softening point being 500 ° C , thermal insulation 300 ° C. It is widely used in the United States, k =0.9. Calcium silicate thermal insulation product is developed in 1970s in China. With high compressive strength, low heat conductivity coefficient, recycle and easily construction, it is widely used in the power system. In China, small workshop production were the most common, then four production lines were gradually introduced from America, including instant fiber forming, dry method punched felt, which are advanced and quality, temperature endurance up to 800-1250 ° C.
Q:What the fireproofing materialare of the refractory kettle and where they can be sold?
Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
Q:What are the applications of refractory?
Refractory materials are widely used in iron and steel smelting , glass, cement kilns, non-ferrous metal metallurgy, environmental protection, and chemical, etc. For example: For a car of 1.5 tons, do you you know how much refractory it use? The answer is: To produce top hat or other steel products, glass for vehicle windows, nonferrous metals kile aluminum and copper, plastic products of the body all needs refractory. A car of 1.5 tons needs to consume a total of 10Kg refractories.
Q:What is high alumina refractory?
It refers to inorganic non-metallic material with refractoriness of higher than 1580℃. Refractoriness refers to the celsius temperature that the cone-shaped refractory sample without load can resist, and under which the sample won't soften and melt down. Refractory material appears together with high temperature technology, and roughly dates from the Middle Bronze age. In the Eastern Han Dynasty (AD25~AD220) of China, fireclay refractories has been used as furnace refractories and saggers for making porcelains. In the early 20th century, refractory material develops toward the direction of high purity, high dense and ultra high temperature products, and meanwhile unshaped refractory and refractory fiber with no need of firing at all and with low energy consumption appear.
Q:What are the characteristics of phenolic resin as a refractory material?
Q:How to choose thermal insulation materials for flood heating?
1, Select the appropriate floor material suitable for radiant floor heating. The floor radiant heating system mainly transfer heat through the ground concrete and the ground material to the room. Therefore in the heating season the ground material will always be heated during heating season. Therefore, it is better to choose stone materials and compround floor plate insensitive to tenmperature change with good heat dissipation and functions. Currently, wood floor is not suitable for the ground radiant heating system. 2, choose the pipe with anti permeability performance. Plastic floor heating pipe itself has a certain air permeability, if oxygen penetrates in it is prone to oxygen erosion and system's mental device will be eroded, resulting in the risk of leakage. Therefore in order to ensure the reliable operation of the heating system, the selected pipe must have anti oxygen permeation performance, and meet the standard stipulated by the DIN4726 oxygen permeation quantity: and be less than 0.1mg\L.d at 40 C.
Q:How long is the duration of fire resistance that fireproof window of level B can endure?
The duration of fire resistance: fireproof window of level A shall not be less than 1.5h, while level B shall not be less than 1.0h. The frame of both fire proof windows A and B are made of steel, and the glass, not less than 26mm, is composite insulation fireproof glass. Monolithic fireproof glass window is neither B fire proof window nor A fire proof window, but non insulated fire proof window.
Q:Who knows what is the requirement for fireproofing of interior decoration materials ?
In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.
Q:which kind of refractory is used in golden smelting furnace? How about his using temperature
generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
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
