- Q: I wanna ask that magnesium oxide is refractory?
- Magnesium oxide. magnesium oxide has high refractory insulation properties. After above 1000 ℃ high temperature burning, it can be transformed into crystals. And it can be transformed into dead-burned magnesium oxide or sintered magnesia oxide until rising to above 1500 ℃. It has heat-resistant, non-conductive at room temperature and relatively poor thermal conductivity. Magnesium oxide is mainly used for the preparation of ceramic, enamel, refractory crucible and refractory bricks. I hope to help you
- Q: Does anyone know what kind of light fireproof materials are there?
- 二, 1, Gypsum plaster board With the building plaster as main raw material, gypsum plaster board is a kind of processed plate made by a special board for protective with an addition of additives and fibers as board core. Gypsum plaster board is characterized by light weight, sound insulation, heat insulation, strong processing performance and simple construction method. 2, Gypsum block Gypsum block is a kind of lightweight building gypsum product which is mainly made of building gypsum, and by adding water, stirring, casting and drying. During the process, , the fiber reinforced materials or light aggregates are allowed in, and the foaming agent can also be added. It has many advantages, such as sound insulation and fire prevention, convenient construction and so on. It is a kind of new and healthy wall material which produces low carbon, enhances environmental protection, and caters to the the times. 3, Fly ash brick is a new type of wall material, and bulk density is one of the main technical indexes. The weight of bulk density can be controlled according to the need of construction and adjustment of technical formula. The dry bulk density of the fly ash brick is about 1540 to 1640 kg / m 3, slightly lighter than the clay brick (1601800 kg /m 3). The flexural and compressive strength of fly ash brick is mainly determined by the production process, the formula and the hydrothermal synthesis reaction mode as well as the need of construction. According to the standards of architectural material industry (JC239 - 2001) released by People's Republic of China, the average value of the flexural strength is 2.5 ~ 6.2Mpa, compressive strength is between 10 ~ 30Mpa. I hope this will be helpful to you
- Q: Who knows about the grade C fireproof door materials?
- There are no differences in the interior materials of the grade A , B and C fire doors, they all use fire?rock?wool?boards. The only difference is the thickness of built-in fire rock wool boards. The rock wool boards' thickness of grade A fire doors is 52 mm, that of grade B is 46mm, and that of grade C is 40 mm.
- Q: What's the material of electrical fire prevention board?
- Electrical fire prevention board uses the material of inorganic binders, which mainly includes water glass, gypsum, phosphate, and cement; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, cornstarch and etc.; electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface. Hope my answer is helpful for you.
- Q: How should fireproof building materials be ranked?
- Division of fire-proof grade of buildings is one of the most basic measures in the fire-fighting technology and measures of buildings. According to our national code of building design, fire-proof grade of buildings are classified into four levels of first, second, third and fourth, of which the first level is the highest in fire resistance and the fourth level is lowest in fire resistance. Fire resistance rating of buildings depends on the combustion performance and fire endurance of the building component. The so-called building component refers to the walls, foundations, beams, pillars, floors, stairs, ceilings, etc.
- Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
- Fireproof of steel components can adopt outsourcing concrete (or laying bricks method), fireproof coatings, fire prevention board coated and composite structure. Anti-firing plate can be divided into the fire protection lamella thickness plate and thin plate. Fire protection lamella thickness plate is of 20 ~ 50 mm. There are mainly calcium silicate and decayed stone of fire prevention board fire board, main varieties KB board, CF board; Fire sheet thickness is between 6 to 15 mm and the main varieties have short fiber reinforced cement pressure plate, fiber reinforced ordinary calcium silicate board and glass cloth reinforced inorganic plate. I hope you can be satisfied.
- 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: How many kilns using refractories are needed? What are the furnaces respectively?
- Rotary kiln, general alumina bricks, high alumina bricks, corundum - mullite brick and vertical kiln. I am limited. Please forgive me that I can only talk about what I know. There are tunnel kiln, clay brick, etc. which can be used in these kiln and shuttle kiln and so on. Shuttle kiln.
- Q: What kind of materials are needed to make refractory bricks?
- Fubang Decoration of Anhui province help you with the question: According to requirements, there are different materials, acid refractory material, such as silica bricks; neutral refractory material, such as high alumina brick; and basic refractory material such as magnesia brick.
- Q: Introduction to refractory material
- Refractory material refers to inorganic non-metallic materials with refractoriness of no less than 1580℃. Refractoriness refers to the centigrade temperature of refractory cone sample in the case of no load when resisting high temperature without softening. But the refractoriness alone cannot descript the refractory material, thus 1580℃ is not absolute. Now refractory material is defined as material used in high temperature allowed by its chemical properties. Refractory material is widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate and power industrial area, of which the application in metallurgy accounts for the largest part of 50% ~ 60% of total output.
