Q: Who knows how many fire heat preservation material are there?: They can be divided into wood fire, steel fire and stainless steel fire. Wooden fireproofing material is light weight, easy for installation and second decoration, as well as all types of civil construction and some industrial buildings. It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: 1 thermal insulation materials with class A combustion performance Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar.

Q: What is the main constituent of refractory brick?: There are several refractory bricks, including clay brick, carborundum brick and chromium-carbon. The type you said may be refractory bricks made from bauxite.

Q: how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q: Refractory material, refractory brick: Refractory materials of various varieties, different uses, it is necessary to scientifically classify refractory materials, so as to facilitate scientific research, rational selection and management. There are many classification methods for refractory materials, among which chemical properties classification method, chemical mineral classification method, production technology classification method, material form classification method and so on are included.

Q: The difference between refractory and thermal insulation material: Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.

Q: Ask some questions about refractories: Application: it is suitable for blast furnace tapping system.

Q: What is the definition and classification of amorphous fire resistance materials?: 9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture

Q: Does anyone know what is a lightweight refractory material?: The volume shrinkage is larger, and the corrosion resistance is higher at high temperature. A lightweight refractory material, used as thermal insulation material in industrial furnace and other thermal equipment, has poor wear resistance, weak mechanical strength and small volume density. Compared with ordinary refractory bricks, the lightweight refractory with low thermal conductivity has higher porosity.

Q: Can polystyrene foam color steel plate be used as decorative fireproofing material ?: Polystyrene foam plastic can not be used as fireproofing material; polystyrene foam plastic is made up of polystyrene resin as main component, foaming?agent and other additives. It is a buffer material which is most widely used[1]. It is closed hole structure, so it has low water-absorbing quality and excellent water resistance; low density, about 0.015 ~0.03; good mechanical strength, excellent buffer?performance; good machinability, easy to be moulded; good dyeing property, thermal adaptability and anti-radiation; high dimensional accuracy, uniform structure. Therefore, it has a large share in external wall thermal insulation. But it will emit polluted styrene gas when burning. It is a kind of class B material in construction.

Q: What kind of refractory decorative board has good quality?: Formica, Grignard, Wilsonart, Yami Home, Germany Board and Priscilla Board are all good choice. They are the high-end brands in fireproof?panel. Hope it is helpful to you.
