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: Is refractory material harmful to human body?: Part is harmful to human body, mainly refractory raw material, silica powder inhalation can cause lung tuberculosis, siliceous fiber on the human body does have great harm, in fact, like other inorganic fiber in the inhalation of the trachea or lung after the same harm to human

Q: What's the fire?retardant material of roller shutter fire resistance door ?: Core board of fire door materials are composited by inorganic materials, and the main components are perlite, inorganic adhesive and other special formula. It has flat and smooth surface, unibody. It is fireproof, sound and thermal insulating. It has passed tests of Tianjin Fire Research Institute and Beijing construction institute.

Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: See which port, if it is from the border (Pingxiang, Dongxing port), will not be needed.

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: How to count the construction costs of refractories?: In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.

Q: How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !: From the perspective of appearances, grade A is 70mm, B 50mm. Their materials are the same .

Q: What is the new fireproofing standard of external wall thermal insulation materials?: 1, The height of fire barrier zone is not less than 300, and the thickness is same to the external insulation system; 2, the horizontal dividing joint should be set on the boundary between fire barrier zone and thermal insulation system; 3, Fire barrier zone is usually set in the horizontal direction, the fire barrier zone should be set above the door and window openings, the distance between the low edge of barrier zone and upward side of the hole should not exceed 500mm; 4, The construction of fire barrier zone insulating layer should carried on from bottom to top with EIFS insulating layer, which is not first leave the place in the EIFS insulating layer, and then paste fire barrier zone insulation board; 5, pasting the insulation board fire barrier zone insulation board and EIFS insulation board should be stitched closely, the width is more than 2mm gap application EIFS insulation materials or fire-retardant foam polyurethane padding;

Q: What types of steel are silicious quicksand and chromium quicksand used in respectively?: Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.

Q: What kind of refractory material should be used for common boiler?: Build by using clay refractory mortar. Common clay brick is used as combustion layer. Xindeyuan Refractory Material, red?brick is used as external wall. Light clay brick is used as thermal insulation layer, thank you.

Q: What's the fire endurance of A grade fireproof glass curtain wall?: According to the latest requirement, fire door has three types of FMA, FMB and FMC, of which A, B, C refer to the class. Take FMA as an example, it refers to A class fire door (namely thermal insulation fire door). The fire endurance of these three types all can be 0.5h, 1.0h, 1.5h, 2.0h or 3.0h, and the specific fire resistance time needs to be determined by the design. Generally the design drawing will make clear of it. As to A class fire door, its fire endurance is 1.5h.
