$Ceramic Fiber Refractory Material For Furnace$

Q:what is best for making refractory insulation for Blast furnace, hot stove.: clay brick, insulating brick can endure relatively high temperature and last longer than the general fireproof fiber.

Q:What things and cement mixed can act as refractory?: This has a lot. I suggest you can check monolithic refractories.

Q:Why do magnesium oxide refractory bricks can be made into refractories?: Because the magnesium oxide, commonly known as magnesia, which is a basic oxide, with the common property of alkali oxides and belongs to the cementitious material . It is white or light yellow powder, odorless, tasteless, non-toxic and a typical of alkaline earth metal oxide, whose chemical formula is MgO. It is white powder, with melting point of 2852 ℃, boiling point of 3600 ℃ and relative density of 3.58 (25 ℃). The magnesium oxide that is soluble in acid and ammonium hydroxide solution has high insulation properity. After high temperature of above 1000 ℃ burning, it will transform into crystals, and when rising above 1500 ℃ , it will turn into dead-burned magnesium oxide (also known as the magnesia) or sintered magnesia. So the performance of magnesium oxide refractory bricks is good, and the fire resistance of it is very strong.

Q:Who knows the roofing fireproofing and waterproof material?: Colorful glass?fiber asphalt shingles the roofing through special materials treatment just like wearing a waterproof, fireproof coat, water rolling down from the roof is similar to the effect of lotus leaf drops, the wall will be always in the dry state, having excellent waterproof, mould proof, efflorescence and weathering. It can prevent the growth of moss and keep the surface clean. And let your roof does not change color for a long time. Colorful fiberglass asphalt shingles materials are widely used in: All types of buildings roofing waterproofing, leak, fire, pollution, wind, and mould proof and moisture-proof of libraries and archives. The color retention of ancient architecture and protection of human cultural relics. Through the number of ten million square meters of engineering applications and two decades of practical test, it welcomed by users.

Q:I wanna ask what are the acidic refractories?: (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.

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:What is the fire resistance thickness of the thin fire-retardant coatings?: There is no detailed requirement on the thickness of the thin steelwork fireproof coatings in the "Code for application technology of steelwork fireproof coating", and the thickness there refers to a certain thickness which must(at least) have fire resistance for a certain time. The thickness of fireproof coatings in engineering generally depends on the manufacturer's test reports. Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.

Q:What are the main characteristics of the sic refractories?: The physical properties of SiC refractories include structural properties, thermal properties, mechanical properties, usability and job performance. The structural properties of refractory include porosity, bulk density, water absorption, air permeability, an the distribution of pore size. The thermal properties of refractory include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, and thermal emission rate. The mechanical properties of refractories include withstand voltage strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength, and elasticity modulus. The usability of refractories include refractoriness, load softening temperature, linear?change?on?reheating, thermal shock resistant performance, slag resistance, acid resistance, alkali resistance, hydration resistance, corrosion resistance to CO, conductivity, and inoxidizability.

Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: If the outer packing is made of solid wood, it must be fumigated! If it is not solid wood, you can do without!

Q:Which industry does refractory belong to?: It belongs to inorganic refractory: Ceramic refractory bricks (used in steel-making furnaces) There is also organic polymer in heavy industry: Halogen-containing and halogen-free It belongs to construction industry.
