Product Description

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

The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond.

Its mechancial intensity is greater than fused alumina, but is brittle and very sharp. The mineral has some electrical and heat conductivity.

Black silicon carbide is typically used for machining or finishing cast iron ,non-ferrous metals, stone, leather, rubber, and other materials where sharp cutting characteristics are important .

Black Silicon Carbide is brittle and sharp and has electrical and heat conductivity in some degree.

Aplications :
Black Silicon Carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing.

The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, Ceramic, etc.

Black Silicon Carbide is also broadly used as high-grade refractory material and metallurgical additive.

Q:which kind of material should be used in fireproofing cabinet?: Cabinet fireproof?panel can be divided into fiber cement fireproofing board, metal fireproof?panel, mineral wool fireproof?panel, perlite fireproof?panel and many other fireproof?panels. Wherein fiber cement fireproofing board is a new material with growing popularity , it has good thermal insulation and sound insulation performance and belongs to a1 level fireproofing material. Fiber cement fireproofing board is a kind of decoration sheet that takes silicious material or calcareous material as the main raw materials and is made by being combined with fibrous material and other additives in certain proportion. Metal fireproof?panel is a kind of sandwich dalle that takes aluminium plate, stainless steel plate, colorful steel plate and other metal materials as main raw materials and is made by adding some fire?retardant materials. Mineral wool board is a kind of fireproofing decorative board that takes mineral wool and glass wool as the main raw materials. Perlite fireproof panel is a kind of fireproofing hollow plate that take low alkalinity cement as the main materials and fireproofing perlite as filler.

Q:Does anyone know the refractory temperature of fire-resistant glass?: Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. If the overall glass is not heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes

Q:The performance of refractory material: The mechanical properties of refractory material include withstand voltage strength. The structure properties of the refractory materials include porosity, bulk density, such as thermal emission rate. The physical properties of the refractory materials include temperature conductivity structure performance, wear resistance, hiphotos, electrical conductivity, creep, the hydration resistance, adhesive strength.

Q:What requirements should refractory materials meet?: The operating temperature of forging furnace is above 1000, which can ensure the normal operation of the furnace, prolong the life of the furnace and save energy. General requirements for refractories are as follows. 1 They should deform at a sufficient temperature without melting. 2, They should have necessary structural strength without softening and deforming. The volume should be stable at high temperature without expansion, contraction or cracking. 4, They can resist erosion of molten metal, slag, gas and other chemicals.

Q:How to divide fire rating of decorating materials ?: Decorating materials shall be divided into four levels according to combustibility. Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability.

Q:What is the role of the vermiculite fireproof material?: Apart from inflaming retarding, the materials covered with vermiculite has a lot of advantages including anti rust, waterproof, anticorrosive, wear-resisting, heat-resisting and the coating is armed with toughness, colorability, adhesiveness, fast-drying and luster.

Q:How should refractory cement be used?: Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will generate a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees.

Q:What's the fire?retardant material of roller shutter fire resistance door ?: They are composited by inorganic materials, and the main components are perlite, inorganic adhesive and other special formula. It has flat and smoothe surface, unibody and stronger strength after molding. It has owned Chinese and Taiwan strength patent. It is fireproof, sound and thermal insulating. It has passed tests of Tianjin Fire Research Institute and Beijing construction institute. It is an ideal product.

Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?: There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.

Q:What's the poured refractory material?: According to the volume density, it can be classified as follows: Heavy (>2.0g /cm3), medium heavy (1.0-2.0g/cm3), light (0.4-1.0g/cm3); classified by binding agent: hydraulic bond, chemical bond, coagulation binder, hydraulic and coagulation binder; classified by material: material of clayey, high alumina, silicious, magnesian, alumina-magnesia, magnesian-chrome, magnesia-zirconia, silicon carbide-based, etc.
