Q:What are the models of refractory cables?
There are bout four types. 1.NA-YJV / NB-YJV Crosslinked polyethylene insulated PVC sheath A (B) class fire-resistant power cable 2.NA-YJV22 / NB-YJV22 Crosslinked polyethylene insulated steel belt braiding PVC sheath A (B) class fire-resistant power cable 3.WDNA-YJY / WDNB-YJY Crosslinked polyethylene insulated polyolefin sheath A (B) class low smoke no halogen fire retardant power cable 4.WDNA-YJY23 / WDNB-YJY23 Crosslinked polyethylene insulated steel belt braiding polyolefin sheath A (B) class low smoke no halogen fire retardant power cable
Q:How can refractory material of the electric furnace be used for longer.
Do not exceed the temperature, do not exceed the limits of use in order to achieve the best performance and the longest service life
Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
What you said is the pixel! Only that has b1b2. Level b1 is the fireproofing level b1, because the particle does not belong to the fireproofing material. Only can fire retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name.
Q:The manufacturing technique of refractory material
The major components of alkaline refractory material include magnesium oxide and calcium oxide. The commonly used alkaline refractory material is magnesia bricks. The magnesia bricks with 80%~85% magnesium oxide has good resistance to basic slag and slag and higher refractoriness than clay bricks and silica bricks. It is mainly used in open hearth, oxygen blowing of converter, electric furnace and smelting non-ferrous metal equipment and other high temperature equipment. Refractory materials applied on special occasions include high temperature oxide refractory materials such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, etc., refractory compounds such as carbide, nitride, boride, silicide and sulfide, etc., and high temperature composite materials, including metal ceramics, high temperature inorganic coating and fiber reinforced ceramics, etc. Consult and find reference for efractory materials production equipment, go to http://hi.baidu.
Q:what's the detailed address of fireproof and thermal inuslation matertial market?
Following are the detailed addresses of fireproof and thermal inuslation matertial markets: Kunpengyu thermal insulation material co., LTD., Bantian street Daoban xuegang road 1-4, Jindu business building 503, Shenzhen Huameida rubber and plastic thermal insulation material wholesale, Shenzhen Longgang district Nanlian road 7, Nanpeng thermal insulation material Xiangxin road 1-4.
Q:What's the A class fireproof and thermal inuslation matertial for external wall?
First, external wall thermal insulation material: 1. silicate insulation material; 2. glue powder polyphenyl granule; 3. cement cystosepiment with the use of steel wire gauze (polystyrere); 4. extruded sheet; Second, roofing materials: 1. xps extruded sheet; 2. EPS foam board; 3. perlite and perlite brick; 4. vermiculite and vermiculite brick; Third, materials for heating power and air conditioners: polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Fourth, steel structure material: polystyrene, extruded board, polyurethane board, glass cotton lap felt, etc.
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.
Q:how about the performance of aluminum silicate fire proof thermal insulation?
aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing agent, molding by high temperature and high press. the density of fiber. tha above information is coming from the Internet and it is just for reference.
Q:Who knows about the types of Dalian thermal insulating and refractory materials?
(1) rock wool board: the heat conductivity coefficient is 0.041-0.045. It is fire retardant, has a great temperature absorption while a poor thermal insulation performance. (2) glass wool: it is simple in construction and free in cutting. It has advantages of antibiosis, mould proof, aging resistance and anticorrosion, and can ensure a healthy environment. It has a low hygroscopicity and a stable physical property. (3) expanding polystyrene board(EPS board): thermal conductivity: 0.037-0.041, it has a good thermal insulation performance, cheap price but a poor intensity. (4) extruded polystyrene board(XPS board): thermal conductivity: 0.028-0.03, it has a better thermal insulation performance, high intensity, moisture resistance while it is expensive, and requires surface treatments during construction. (5) gelatine powder polyphenyl granule heat insulating slurry: heat conductivity coefficient: 0.057-0.06, it has a good flame resistance while a poor thermal insulation performance, as well as has high construction requirements and can be recycled. (6) polyurethane foam: heat conductivity coefficient: 0.025-0.028, it has advantages of waterproofness, thermal insulation, high intensity, high integrity, and good integrity, but it has a poor fireproof performance and is more expensive. (7) rigid polyurethane: heat conductivity coefficient: 0.018-0.023, it has advantages of low heat conductivity coefficient and good thermal performance. When the unit weight of rigid polyurethane is 35 to 40kg per cubic meters, it is equivalent to half of the EPS. It is the one with the lowest heat conductivity coefficient among all the thermal insulation materials. (8) perlite slurry: heat conductivity coefficient: 0.07-0.09, it has advantages of fire and high-temperature resistance, and high water absorption but is poor in thermal insulation.
Q:How can refractory materials be divided?
There are many criteria for the classification of refractories.Just referring to a book about refractory.
