Q:How to determine the fire resistance rating of the aluminium-plastic?panel?

Class A incombustible and thermal insulation material: inorganic active wall thermal insulation material, cement foam insulation board, glass bead thermal mortar, rock wool board, glass wool board, foam ceramics, etc. With many characteristics of low density, low thermal conductivity, high pressure bearing capacity, convenience of construction, economy and durability, A class incombustible material is widely used as thermal insulation material for heat pipelines, thermal equipment, other industrial pipe-line equipment and industrial buildings, and thermal insualtion and sound absorption material for the building envelop of industrial and civil buildings. Because of good thermal stability, it is more often used as fire-proof and protective coating material of the steel structure.

Q:What's the material of electrical fire prevention board?

Electrical fire prevention board uses the material of inorganic binders, which mainly includes water glass, gypsum, phosphate, and cement; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, cornstarch and etc.; electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface. Hope my answer is helpful for you.

Q:How much is the duration of fire resistance of the porous brick shale?

This is really a simple question. The temperature should be limited within 1050℃, or it will be scorched. I think 980℃would be acceptable.

Q:Why can aluminium hydroxide not be used to make refractory material?

Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.

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 types does refractory floor include?

The categories of refractory are: 1. the best overall performance stone flooring (waterproof, fire retardant) The full name is microcrystalline stone flooring. It is a high-performance waterproof and fire-retardant environmental wood floor synthesized with high and new technology. Its unique raw material is ground calcium carbonate micro-crystalline polymer stone with natural resin and other twenty more imported spreadings. It is formed by refining with high temperature (300 degree centigrade) and high pressure (9,000kg). It is an environmental healthing high-performance material. Its product is innocuous and unpoisonous, and won't age, deform, fade while it is fire retardant, waterproof, maintenance-free and quality, so it is an inevitable repalcement with traditional wood floor. This product has been confirmed as national key promotion program. 2. Wear-resistant composite solid wood floor It is also known as super wear-resistant multi-layer solid wood floor. First stiffening layer surface (based on inorganic materials and steel fibers for paper impregnated with thermosetting amino resin with solid wood or plywood blockboard substrate surface as a combination of facing layer), the front is wear-resistant layer, and the back is balance layer. Thtough hot pressing, it is a grooved and tongued floor, a new impregnated paper laminate floor. It also has the same wear-resistant quality as laminate floor, beauty and foot feel as solid wood floor, stable structure as solid wood composite floor, etc. 3. Waterproof plastic wood floor Plastic wood (also known as "wood plastic" or "plastic wood") composites, and the English name is WOOD-PLASTIC-COMPOSITES, WPC for short.

Q:Which company needs the new refractories?

The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.

Q:Development trend of refractories

The foundation of China's refractories industry is still relatively weak, the utilization level of refractory material resources is low, the quality of refractory materials is not high, excess production capacity of ordinary products, the key products of some high-quality high technology content can be produced, but the quality is not stable, and the service life of refractory material consumption compared with foreign advanced level, there is a considerable gap. Therefore, the new trend of tracking foreign refractories science and technology development, carry out and supporting the development and application of advanced and basic theory research, to promote technological innovation of refractory materials, optimizing product structure, industrial structure adjustment, implementation of the strategy of sustainable development, it is very necessary.

Q:Who knows the new fireproof and thermal inuslation matertial?

New fireproof and thermal inuslation matertial: foam concrete building blocks brick. The foam concrete building blocks brick is a new fireproof and thermal insulation material, with distinct advantages compared with the organic insulation material . Foam concrete can be used as wall materials, and it has a good self-insulation properties, so there is no problem of dropping off the outer insulating layer. A small part takes external wall exterior insulation, with mostly anchoring or dry hanging, which are not easy to fall off. Very few uses paste. Since the foam concrete and wall materials are of the same nature and strong adhesive, so it is also not easy to fall off.

Q:I want to know what is the slim in the refractory bricks

lining brick and refractory clay in the teeming ladle; high alumina brick, high alumina lining brick and high alumina refractory mortar can make cement kiln and glass melting furnace in the building materials industry for anti-slide. Taiyuan in Shanxi province is the famous place of origin; hard paste in the refractory clay is used as blast furnace refractory: // b, in agriculture as a fertilizer high alumina clay is also used in oil wells, which generally do not dip in water; accounting for 2/3 of abrasive products in the metallurgy, hard and semi-hard clay can be manufactured as ceramics for daily use. what you said should be slime. High-alumina clay can be resistant to high temperature after calcination! Refractoriness refractory clay refers that the refractoriness is more than 1580 ℃ with greater hardness and specific gravity and high refractoriness. except higher refractoriness, such as aluminum sulfate, the dosage accounts for about 70% of refractories; refractory clay and high alumina fused cast brick are widely distributed in China.
