Q:How can refractory materials be divided?
There are many criteria for the classification of refractories.Just referring to a book about refractory.
Q:Fire rating of decoration materials
code for fire protection design of buildings
Q:how does the fire endurance of first rate fire resistant window?
the classes are different. class A window not less than 1.5 hours, and the time is short, class B window not less than 1 hours, with shorter time, Class C window not less than 0.5 hours.
Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.
Q:How long is the duration of fire resistance that fireproof door of level B can endure?
According to the duration of fire resistance, fireproof doors can be divided into three levels, namely level A,B,C. And accordingly, the duration of fire resistance of them should not lower than 1.20h, 0.90h and 0.60h. Fireproof door, a door that can meet the requirements of fire resistance stability, fireproof door integrity and thermal insulation at a certain time, is a fireproof separator which is located in fireproof partition, emergency staircase and vertical silo. Apart from functioning as a common door, a fireproof can also prevent the spread of fire and smoke in a certain period to make sure that people are safely evacuated.
Q:What is the main material of fireproof wooden door?
Fireproof wooden door has a lot of materials! including imported timber decorative effects: utilizing the diversity and easiness to cut of the timber, with all the decorative characteristics of the timber. Material selection features, door frames: Using high-quality hardwood, such as imported miscellaneous wood, camphorwood, lauan, hemlock, etc., insetting fire and smoke proof adhesive tape
Q:What is refractory material?
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
Sodium silicate, pure calcium aluminate cement, boric acid
Q:Does anyone know the characteristics of refractory for glass kiln?
The characteristics of refractory for glass kiln: First, it can well resist the erosion of glass fusant and gas actor, and has sufficiently high load softening temperature and thermal stability. Usually we hope the refractories of all parts of the furnace will has no partial early erosion phenomenon to ensure that the entire furnace has a sufficiently long service life. However, due to the different mechanical, physical and chemical conditions of different parts of glass furnace, the performance of refractories should adapt to the glass furnace thereto and at the same time has no adverse effect on the adjacent other kinds of brick materials. Besides, we should consider the price of brick material, we should try to consider using commonly used stereotypes bricks of standard sizes which is cheap and quickly supplied by the warehouse. The damage of glass melting furnace lining is mainly due to chemical erosion, assisted by thermal stress. The degree and speed of chemical erosion is closely related to the applied parts, furnace temperature and melting glass varieties, and of course, the quality of the lining itself is also crucial. The nature of refractories using in the glass furnace has a very significant impact on the operation of glass melting furnace and the quality of glass. The application of poor main beam refractories will not only cause frequent shutdown for maintenance, limiting melting temperature, lowering furnace output, but also shorten the life of the furnace, and make glass has a variety of defects (stripes, stones, etc.), lower the quality of the glass. Here are the description of the nature and purpose of commonly used refractory in glass furnace.
Q:Who knows what is the external wall thermal insulation materials for level A fireproofing?
external wall thermal insulation materials level A fireproofing: Incombustible building material is a material that does not occur any burning. Class A1: Monomer inorganic non-combustible. Noncombustible means no open fire. Class A2: Non-flammable organic compound is namely composite materials and non-flammable, the amount of smoke must be qualified. Class B1: nonflammable building material: non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion source is removed, the combustion will stop immediately. Class B2: combustible building materials: flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs.
We has been adhering to scientific and technological innovation as the company development ideas, establishing the export-oriented development strategy and has close technical cooperation with scientific research institutions.We supply many kinds of calcined bauxite.
