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: How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?: Level A of non-combustible insulation materials are: W W inorganic active wall insulation materials, cement foam insulation board, glass beads of insulation mortar, rock wool board, glass wool board and foam ceramics, ect. Th e level A is non-combustible material, characterized with low density, low thermal conductivity, high bearing capacity, convenient construction, economy and durablity, and widely used as the thermal insulation materials in hot pipes, thermal equipment and other pipe-line equipment and industrial architectures, and as the thermal insulation, heat insulation and sound-absorbing materials in industrial and civil building envelope. Because of its good thermal stability, it is more used as fire-resistant protective coating material of steel structure.

Q: I wanna ask about the building insulation materials fire rating?: Hello, I am happy to answer your questions about the classification of building insulation materials fire rating: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope I can help you

Q: How long does it take for refractory cement to solidify?: 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.

Q: Which industry does the metallurgy and thermal insulating and refractory material belong to?: Metallurgical industry and refractory industry.

Q: Who knows about the grade C fireproof door materials?: grade C fireproof door materials: 1. the doorframe raw materials of grade C fireproof doors: the galvanized?steel?sheet is no less than 1.2 mm(the thickness of steel plate is no less than 1.5 mm when the height and width of doors are more than 2.1 m and 1.2 m respectively). 2. the door leaf raw materials of grade C fireproof doors: the thickness of galvanized?steel?sheets is no less than 0.8 mm. 3. the reinforcement raw materials of grade C fireproof doors: the thick?steel?plate is no less than 1.2 mm, if there are bolt-holes, the thickness of which is no less than 3.0 mm. 4. filler: The fireproofing filling materials that fit the environmental and standard needs(for instance, door leafs are filled with perlite fireproof materials inside, and doorframes are filled with fire-resistant cement) meet the test criterion promulgated by the relevant state departments. 5, the sealing requirements: there are seal grooves in doorframes and within which are embedded with refractories.

Q: What are the main components of refractory cement?: Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. 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. 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.

Q: I wanna ask what are the acidic refractories?: You can look at these: (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. I hope it is useful!

Q: What are the materials of class A fire resistant window?: Environmentally friendily, non-poisoned non-peculiar smell, non-radioactive; non-combustible, fireproof, moisture-proof, corrosion-resistant; easy to operate, lightweight, high strength, themal insulation, sound insulation; able to be cut, planed, sawed and carved. It also meets GB8624 -2006A1 level non-combustible standards. Lightweight, high strength, anti-aging, corrosion resistance; meeting the GB / T20285-2006 Opium (AQ1) safety and environmentally friendly products; Foamed fire door core board specifications: 2100 × 900 × (26 ~ 65) mm; 2050 × 850 × (26-65), and many other specifications. I hope my answer can help 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.
