Q: What are the fire endurance requirements of class A fire resistant door ?: Hardwares are professional fire resistant lock, fireproof?door closer, fire hinge, handle, latch and sequencer, and they can also be configured according to user needs. Fire resistant time of class A and B fire resitant door is 12h and 09h respectively. It can also be customized according to customer needs into a variety of non-standard specifications. Steel fire door is developed in accordance with the national standard GB12955-2008, and in line with ISO3008, BS476 standards. Requirement: fire endurance should meet the A,B and C fireproof requirements respectively. You can also choose to install hold-open door device to leep the door leaf usually in open. Doorframe and door leaf is made up of imported or domestic quality electrolytic steel plate, electro galvanized steel plate or stainless?steel plate, filled with quality expanded perlite fireproof?panel which can withstand high temperature above 1200 ℃. The surface is processd with electrostatic spraying plastics, and auxiliaries are stainless steel fire resistant lock (or pipe shaft lock ) , galvanization for steel (or stainless?steel) fire hinge, domestic(or imported) door?closer.

Q: Can someone professionally introduce the classifications of refractories?: It can be divided into two categories of ordinary and special refractory. Ordinary refractories can be devided into acidic, neutral and alkalinee refractories according to chemical properties. Special refractory can be devided into high temperature oxide, refractory compounds and high-temperature composite materials according to the compositions. Furthermore, it canbe devided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and super refractory products (above 2000 ℃) according to the strength of refractoriness. It can be divided into bulks (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and Indefinite shape (refractory clay, castableand ramming mass, etc.) according to the shapes of products. According to the sintering process, it can be divided into sintered products, cast products, melting jetting products.

Q: Are the specification of fireclay bricks and ordinary clay brick the same?: Do you want to know whether the specifications of fireclay bricks and ordinary clay brick are the same?

Q: As for fireproofing material rock wool and glass wool, which one is better?: As for fireproofing effect, the effect of rock wool is certainly better than glass wool , the highest temperature of rock wool is 1100 ℃, but the temperature of glass wool is only 600 ℃. In addition, if it's used in the external walls, then,unit weight of the glass wool is limited,and high unit weight can only be 60-90, but unit weight of rock wool can reach over 140, now external wall can't use glass wool, and only rock wool is A class fireproofing material. glass wool has lower thermal conductivity, rock wool has longer fiber length,as for the price, tons price of glass wool is more expensive than rock wool, but if it's acculated by square, square price of glass wool is cheaper than rock wool.

Q: Who knows about the fire endurance of sintered shaly hollow bricks?: Sintered shaly hollow bricks of Chu area have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance. The fire endurance of sintered shaly hollow bricks should not exceed1050 degrees otherwise they will burn excessively. I, actually, think that the temperature should be controlled within 980 degrees. I hope my answer may help you.

Q: Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks: Bricks are usually made from pallets.Generally take the automotive, coastal sea city.

Q: Which brand of refractory fiber hard thermal insulation board is better?: One colleague said Huayou refractory fiber hard thermal insulation board is good. The size (mm): 600*400*60. refractory temperature: 1770 ~ 2000 ℃ (℃), and the price is 2850 yuan a ton.

Q: How many types of fire-resistant material?: 1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.

Q: How many external wall thermal insulation fireproof material are there: Class A exterior wall insulation: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic foam, foam glass

Q: What are the materials used in refractory material processing?: AZS special refractory brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on. Unshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
