- Q: hat kind of fire retardant materials are there
- At present, there are mainly organic and inorganic flame retardant materials, halogen and non halogen. Organic flame retardant materials are represented by bromine, nitrogen and phosphorus and its compounds; Inorganic fire retardant materials include antimonous oxide, magnesium hydroxide, aluminum hydroxide, and silicon. Generally speaking, organic flame retardant materials have a good affinity, and can be added in the plastics. Brominated flame retardant agent occupy the absolute advantage among organic flame retardant system, though it’s “controversial” in terms of environmental protection, it has been difficult to have other flame retardant system replaced.
- Q: How to understand qualitative and qualitative refractory materials?
- Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
- Q: What kind of material is good for cabinet fireproof board
- Cabinet fireproof plate can be classified into fiber cement fireproof board, metal fire proof board, mineral wool fireproof board, perlite fireproof board, all sorts of fire prevention board. Fiber cement fireproof board is a kind of ornament plate using siliceous or calcareous as main materials and combined with a certain proportion of fibre material; metal fireproof board is a kind of decorative plate made of aluminum plate, stainless steel plate, color steel plate and other metal materials as the main raw material and added by certain flame retardant materials. Mineral wool fireproof board is a decorative plate made of mineral wool and glass wool; perlite fireproof board is hollow fire proof plate made of low alkalinity cement as the main raw material, and supplemented by certain perlite with fireproof function as filling.

- Q: How to divided the grade of external wall thermal insulation materials?
- 1, According to China's national standard GB8624-97, combustion performance of building materials will be divided into the following grade level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level 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. Level 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. Level B3: Combustible?building?materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high. 2, The external wall thermal insulation materials is divided by fire rating 1) level A combustion performance thermal insulation material Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope my amswers are helpful to you

- Q: What are fire?ratings of wall thermal insulation material?
- External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible?material, while grade B is combustible?material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake. It is recommend to find a large manufacturer with complete formalities, such as provincal records of production, provincal records of use, city records, type test report at or above the provincial level, national fireproof report and design drawing collection of department of construction. Lack of any is unsafe. It is recommended to use mortar from Hebei Qizheng Haocheng New Building Material Co., Ltd. It is absolutely large manufacturer. MPC thermal?mortar produced by it is recommend product of Department of Construction in Hebei Province! Generally speaking, the combustion of phenolic aldehyde is grade B, but it can barely reach A2 when a thin layer of mortar is wiped outside.
- Q: What are the fireproofing materials of the external wall included?
- According to the external wall thermal insulation materials, the external insulation materials is in general divided into Class A and Class B. The A class is non-combustible material. The B class is combustible materials. The fire disasters of the CCTV building and Shenyang hotel are both caused by the B level materials. Generally, the A level material will be used, and some prices are even cheaper than the B-grade material. A level is roughly divided into thermal?mortar, phenolic foam Board, rock wool board, foam cement board, and so on. I hope my answer will help you!
- Q: Development trend of refractory industry
- In the central provinces in Henan, Shanxi, Liaoning China main manufacturer of refractory material, which is the main origin of three China bauxite, magnesite and other refractory materials; refractories industry by the end of May 2009 more than 3236 enterprises; industry revenue reached 67 billion 52 million 540 thousand yuan, Henan Province, Liaoning, Shandong, Jiangsu, Hebei and other regions, and refractories industry in the development of better leading enterprises, such as blue and white, accessible, prco etc. at present, its sales in the industry in the proportion is still small, the largest sales is also inadequate in refractory industry in 4%. An enterprise should play a leading role in leading enterprises in the industry, and its turnover in the industry should be more than 15%. Obviously, at present the refractory industry in the leading enterprises do not have, and the refractory industry concentration needs to be improved, and the existing resources in the refractory industry integration, is undoubtedly the way this process effective and efficient.
- Q: What is the the best ratio of mortar in refractory cement?
- Specifical proportions are as following: 42.5R cement is 425 rapid hardening cement. Using the 425 cement to compound the mortar. The reducion of cement will naturally impact the workability of the mortar. The mix design standard of the mortar specifies the minimum amount of cement is not less than 200kg / m3. If it is composite mortar, and the strength and workability can be ensured, it is Ok to use 425 to compound. You can look for instructions of mixing proportion of mortar online as a reference.
