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: What's the fire?retardant material of roller shutter fire resistance door ?: Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside.

Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?: fused cast bricks, fused zirconia corundum blocks, corundum, high zirconium

Q: what's the fire endurance of fireproof?panel?: fire endurance of fireproof?panel generally is 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof?panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.

Q: Does anyone know which materials belong to light fire resistant material?: Building board of lightweight fireproof partition material: 1, GRC lightweight partition material glass fiber reinforced concrete; it is a kind of fiber cement composite with alkali-resistant glass fiber as reinforced material and cement mortar as the base material . Aerated concrete block equipment foundation construction Its outstanding features are having good tensile, rapture strength and good toughness. This kind of material is particularly suitable for the production of ornament mould and the manifestation of strong texture. Compared with these external wall decorative materials, the biggest advantage of GRC material is to meet the individual needs of architects, completing the expression of various ornament moulds and skin textures. 2, fiber reinforced low alkalinity cement building plate. The standards stipulate the classification, raw materials, technical requirements, test methods, inspection rules, packaging, labeling, transport and storage of the fiber reinforced low alkalinity cement building plate.

Q: How to prolong the furnace age of Induction furnace by using fireproof materials?: magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.

Q: how is the high-temperature flame-retardant fibre board?: high-temperature flame-retardant fibre board is good decorative material. Hope it helps you.

Q: How long is the fire endurance of the rock wool board?: The rock wool board takes the basalt as raw material and is processed into artificial inorganic fiber through high temperature melting, which is light in weight, non-combustible, heat absorptive, small in thermal conductivity. The initial development in construction is a common type of application used for industrial buildings, which should be consistent with the requirements of "building insulation application categories and basic requirements" . In June 1981 the pre-launch succeeds. The rock wool board is a new type of insulation, burning compartment and sound-absorbing material. Generally the fire resistance of the rock wool board is 140-180 degree within two hours, It is best not to exceed this safe period, in order to avoid security risks.

Q: Can anyone tell me what is a high alumina refractory?: High alumina refractories: High-alumina refractory products have high refractoriness, compressive strength and refractoriness under load, which are used for building the high-temperature parts of various large blast furnaces, such steelmaking furnace, airheater, electric furnace, rotary?kiln and other thermal equipment.

Q: Who knows the fire endurance of rock wool color plate?: Colored steel rock wool board is used for areas with high fireproofing requirements. Colored steel rock wool board belongs to class A according to "Fireproof? Specification of Building Interior Decoration?Design" whose lifetime can reach more than 15 years, operating temperature can up to about 700 ℃, maximum fireproofing time is 6 hours. And rock wool colored plate is environmentally friendly materials, which is is the preferred material in the construction industry .
