Black Silicon Carbide 1-10mm 90%

It 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. The mineral is also used widely as a refractory material or metallurgical additive. More detailed specifications can be supplied on your request.

Q:What is refractory brick?: Capability1. Refractory brick is also known as firebrick. It is faint?yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.

Q:Development trend of refractory industry: China announced that from 2004 January, the export of most refractory raw materials will be cancelled, and the export of finished products will also reduce the tax rebate rate. This means that important raw materials for further export restrictions, some developed countries dependent on imports of China's refractory materials and products of the refractories industry will have a major impact. In order to reduce costs, they will move their factories to Chinese, which is the development of Chinese refractories industry will also be an important opportunity. In addition, the convenience of communication and transportation, the change of the international market and the increase of e-commerce have also brought good opportunities to the development of refractory industry.

Q:What is the the best matching ratio of refractory cement?: The best matching ratio of refractory cement is 30%. Refractory cement is also known as aluminate cement. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement. Aluminate cement is often yellow or brown or gray. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc. It is a special cement. I hope my answer will be helpful to you.

Q:How to divide the materials according to the National Fireproofing Material Standard?: 2,generally, the external wall thermal insulation materials is divided in accordance with fire rating: 1, the class A combustion performance of insulation materials : inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement, hole-closed perlite ect.. 2) class B1 combustion performance of thermal insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) combustion performance of class B2 insulation material: molding polystyrene board(EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope it will be helpful for you

Q:What is the quote of fireproof and soundproof materials used in KTV?: 1. fire retardant, sound absorbing sheet,eggs,pyramid,sound-absorbing material, piano room, studio, KTV, with glue on the rear, 15 Yuan 2. bar, KTV, fireproof sound insulation cotton, sound-absorbing materials, studio, eggs, drum practice room, sound-absorbing and sound insulation materials, pyramid, 25 Yuan 3. fireproof wood excelsior absorbent, sound absorbing board, wall ceiling decoration materials, materials, theater, KTV, wood color fiberboard, 30 Yuan.

Q:Who can introduce the external wall thermal insulation materials fire rating regulations?: According to public fire-fighting [2007] No. 182, the contents of the notification on the implementation of a number of issues of national standards GB8624-2006 "building materials and products combustion performance classification", since there is large differences between the new version of the standard GB8624-2006 and the old version of GB8624-1997 in the principle, hierarchical structure and test methods. According to the cintent of notification, in order to ensure a smooth transition between the old and new standards, the current national standard "Fireproof? Specification of Building Interior Decoration?Design" GB50222, "fire?safety?rules of tall civil buildings design" GB50045, "Fireproof? Specification of Building Design" GB50016 have not completed the relevant amendments, the new classification method of GB8624-1997 and GB8624-2006 can be used for temporary reference in terms of combustion performance of materials . From GB8624-2006 standard implementation, the classification of combustion performance is too granular, which do not match to the actual construction of the current project in our country. Therefore, the relevant departments carry on the 3rd amendment for the GB8624-2006 standards, namely GB8624-2012, and it will be released on December 31, 2012 and implemented on October 1, 2013. The combustion grading requirements in the standard: Level A is non-combustible materials (products); level B1 is nonflammable material (products); level B2 is combustible materials (products); level B3 is flammable materials (products).

Q:Are the specification of fireclay bricks and ordinary clay brick the same?: Do you want to know whether the specifications of fireclay bricks and ordinary clay brick are the same?

Q:What is the main material of fireproof wooden door?: Fireproof wooden door has a lot of materials! including imported timber decorative effects: utilizing the diversity and easiness to cut of the timber, with all the decorative characteristics of the timber. Material selection features, door frames: Using high-quality hardwood, such as imported miscellaneous wood, camphorwood, lauan, hemlock, etc., insetting fire and smoke proof adhesive tape

Q:Which industry does refractory belong to? Does it belong to construction industry?: I do not recognize all the answers. No matter what kind of refractory can be used in construction. Biulding syove or kiln is construction. So personally, it belongs to construction indusrty.
