Product Description:

Black Silicon carbide/SiC/Carborundum 90% with high quality

1.Structure of Silicon Carbide Description

Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke.

Black silicon carbide is typically used for working on cast iron ,non-ferrous metals, stone, leather, rubber, and other materials which requires sharp cutting characteristics. The mineral is also used widely as a refractory material and metallurgical additive. 

2.Main Features of the Calcined Bauxite

Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and  has a certain degree of electrical and heat conductivity.

3.Main usage of the Calcined Bauxite

1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials

2.Bonded abrasive tools, lapping and polishing

3.Widely used as a metallurgical additive and refractory material

4.Refractory

Q:What characteristics do A grade external wall fireproofing material have?
For characteristics of A grade external wall fireproofing material, its main raw material uses cold resistant and thermal insulated, environmental protection and energy saving material with good insulation, keeping the indoor temperature steady and making the environment more comfortable. It is several times better than other masonry in overall strength and resist capability, and it can also hang heavy objects such as air conditioners by directly nailing or installing expansion bolts. Single point hanging machine can withstand heavy objects with the weight of more than 45kg. It can also be directly fixed to the tiles, wallpaper, wooden plaques, paint, etc.
Q:Does the production of refractory belong to advanced technology?
Refractories production is advanced technology supported by the state. The refractory enterprise is high-tech enterprises and it needs to apply for it in science and technology bureau.
Q:How long is the fire resistant limit for ultra thin fire retardant coating?
There is no detailed stipulation for ultra-thin fire retardant coating, and the thickness of the inside is the fire resistance limit shall reach certain time(at least). In engineering, the thickness of the fire retardant coating is generally determined according to the manufacturer's testing report. We use thin fire retardant coating for steel structure: if the fireproof limit is 2.5 hours. the thickness should be 4.9mm. If fire-resistant limit is 2 hours, the thickness shall be 3.5mm. If the refractory limit is 1.5 hours, the thickness shall be 1.75mm. If the limit is 1.0, the thickness is 1.17mm hope my answer can help you
Q:What are the new refractories?
Most are ordinary refractories.
Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
Polystyrene foam plastic can not be used as fireproofing material; polystyrene foam plastic is made up of polystyrene resin as main component, foaming agent and other additives. It is a buffer material which is most widely used[1]. It is closed hole structure, so it has low water-absorbing quality and excellent water resistance; low density, about 0.015 ~0.03; good mechanical strength, excellent buffer performance; good machinability, easy to be moulded; good dyeing property, thermal adaptability and anti-radiation; high dimensional accuracy, uniform structure. Therefore, it has a large share in external wall thermal insulation. But it will emit polluted styrene gas when burning. It is a kind of class B material in construction.
Q:What is high alumina refractory?
High alumina refractory: High alumina refractory products, with high refractoriness, compressive strength and refractoriness under load, it is used for masonry of a variety of large-scale blast furnaces such as steel furnace, air heating furnace and electric furnace, and for high-temperature parts of thermal equipment like rotary kilns.
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
They are not the same. If you say the ceramic fibers, they have some common points because the ceramic fiber is one of the refractory. It is belonged to the lightweight refractory which can be considered a new type of refractory with the main ingredient of aluminum silicate (including aluminium oxide and silicon dioxide).
Q:What are the types of advanced refractory?
it can be divided into two categories of general and special refractories ordinary refractories by chemical properties into acidic, neutral and alkaline. Special refractory composition divided by high temperature oxide, refractory compounds and high-temperature composite materials Furthermore, according to refractoriness can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and grade refractory products (2000 ℃ above). the article can be divided into blocks (standard bricks, shaped bricks, etc. ), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron quality, etc.) and a random shape (refractory clay, pouring materials and ramming mixes, etc.) according to the sintering process it can be divided into sintered products, cast products, melt blown products.
Q:How can refractory materials be divided?
Refractory materials in China can be roughly divided into refractory products and unshaped refractories.
Q:how long is the fire endurance of plasterboard?
Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
