Q:What kind of refractory materials are used in metallurgy industry?
Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
Q:Who knows about the types of Dalian thermal insulating and refractory materials?
There are many Dalian thermal insulation materials, which can be divided into organic and inorganic thermal insulation materials. Materials include inorganic thermal insulation materials, polyfoam, mineral wool products, foam glass, expanded perlite insulation products, gelatine powder EPS grain heat insulating slurry, sprayed mineral wool, thermal insulation product of foam cements, and vacuum thermal insulation board.
Q:How to divide fire rating of decorating materials ?
Generally speaking, it is divided into Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability.
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:which kind of material should be used in fireproofing cabinet?
Natural stone,marble. advantage: Colorful, soft texure, natural and diverse texture, easy to cut or engraving molding. Disadvantages: Because it is a natural formation, tiny loose crackle is easily folded, because the stone is porous material structure, if sewage and waste water permeate in the structure in the process of production, transportation or construction, it's difficult to clean and easy to crack. In daily cleaning, it is inevitable that there will be some residue left, and dirt is filled into crack under the wiping of rag and becomes a breeding ground for bacteria. 2, granite. advantages: Granite has big density and high hardness, with wear-resistant surface, it's one of the most common materials for family decoration. Compared with natural marble, it can be used in the materials of kitchen countertops, and granite has good anti-bacterial regeneration ability. Disadvantages: As the cabinet table material, natural stone is usually not very long, so in order to produce a long overall table (especially U-shaped, L-type table), it will certainly exist joints, which are also easy to hide dirt. 3, artificial stone. advantages: Artificial stone has richful lines and colors, and it can be comparable to stone, it's non-toxic, non-radioactive, easy to clean, and can be truly seamless splicing. it belongs to economic environmentally friendly material. Disadvantages: Artificial stone belongs to the processing industry, and has low technology requirements, The inferior products of many small companys are fulled in the market and damage customers' interests. There exist faded color,poor aging resistance,oil stain and other issues in affordable products.
Q:How to classify the grade of wall fireproof and thermal inuslation matertial?
The level classification of wall fireproof and thermal inuslation matertial: Grade A: incombustible building material: Material almost with no combustion. Grade B1: nonflammable building material: Nonflammable material has good flame resistance. It is difficult to fire in case of fire in the air or at high temperature. It is not easy to quickly spread. After the fire source is removed, combustion stops immediately. Grade B2: combustible building material: Combustible materials have a certain flame resistance. It will immediately burst into flames in case of fire in the air or at high temperature and is easy to lead to the spread of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Grade B3: Flammable building material: It has no flame-retardant effect and is highly flammable. Fire hazard is very large.
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:Who knows about the fire endurance of A grade fireproofing glass doors?
The fire endurance of grade A fire resistance rolling shutter doors should be no less than three hours. Fire doors can be divided into A, B and C grades according to their fire endurance which should be no less than 1.20 h, 0.90 h and 0.60h respectively. Places where are difficult to set fire-proof bulkheads can use fire resisting shutters as partitions of fire compartments. The fire endurance of fire resisting shutters that include unexposed surface temperature rise as judging condition should be no less than 3 h. Fire resisting shutters that exclude unexposed surface temperature rise as judging condition should set up independent protection of closed automatic water spray system on both sides of shutters, and the duration of water spray system should be no less than 3.0 h.
Q:What the fireproofing materialare of the refractory kettle and where they can be sold?
Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
