Q:How long is the duration of fire resistance of hollow glass magnesium board
It belongs to second level refractory building. The fire resistance limit of prestressed hollow slab is 0.7 hours, according to provision 3.2.7 and 5.1.5 of fire safety rules. When reaching 20 thick protective layer, the fire resistance limit of the prestressed hollow slab is 0.7 hours. When reaching 30 thick protective layer, the limit of the fire resistance of prestressed hollow plate is 0.85 hours. Protection layer of prestressed hollow board prefabrication is 15, plaster ceiling has 12 protection layers, the total protection layer amounts 27, which can achieve fire resistance limit of not less than 0.75 hour.
Q:What's the fire endurance of hollow brick?
This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980℃ is ok actually. This is the maximum limit.
Q:What are the qualifications of refractory industry?
Certificate for production and sale is needed, just like the certificate for other products.
Q:what is best for making refractory insulation for Blast furnace, hot stove.
clay brick, insulating brick can endure relatively high temperature and last longer than the general fireproof fiber.
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:Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
Directly using silicon molybdenum kiln, the temperature is better. Now using the electricity is cheaper than the price of other fuels.
Q:Does anyone know the difference between refractory and thermal insulation material?
Refractory refers to inorganic nonmetallic material, whose refractorinessis not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulation material also belongs to refractory as long as its refractoriness is higher than 1580℃.
Q:What's the requirements of fire-fighting criteria of heat insulating material?
It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.
Q:Who knows the fire endurance of rock wool color plate?
I'm glad to answer your question and offer you some of my experiences, for reference only. In fire safety rules, it can be divided into non-combustible component, hard-combustible component, combustible component according to the combustible degree of building materials. Rock wool board is building board recombinated artificially by fibers processed by coated steels and inorganic minerals like basalt mineral, because steel plate and rock wool which is the main components are non-combustible material, so rock wool board should be considered as non-combustible component. The fire endurance of rock wool board has its own judging criteria. Lose sustaining power, integrity and fire insulation function. Its fire endurance is within 2 hours.
Q:What's the commonly used refractory material for ladle?
1. According to the refractoriness, it can be classified as follows: common refractory: 1580℃ ~ 1770℃; high grade refractory: 1770℃ ~ 2000℃; superrefractory: 2000 ℃; 2. According to the shape and demension of the product, it can be classified as follows: standard form : 230mm×113mm ×65mm of no more than four measuring scale, (demension ratio) Max: Min
