Q:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;
Q:Which are fire proofing thermal insulation materials?
Fire proofing thermal insulation materials include: fire proofing heat insulating brick, fire proofing thermal baffle, fire proofing thermal insulation paper, fire proofing thermal insulation felt, fire proofing blocking, fire proofing fiber bulker, castable refractory, etc. Yizhen Decoration wish you a happy life!
Q:What are grade classifications of the external walls for fireproofing?
The classfication of external wall material fire rating is as follows: Level A: Complete retardant building materials may not occur combustion, and the cost is relatively high, home decoration do not need such a high standard. In general, it can be used in the arms powerhouse and electrical appliance store. Level B1: non-flamble construction material has high flame-retardant, it will not be burn under the conditions of open fire and high temperature, but if it is attacked by these two conditions, it may still be burning. However, when the source of fire is transfered, it will be immediately extinguished. Level B2: Combustible building materials have a certain degree of flame resistance, but the effect is very little. Under the condition of sufficient air, it will break out fire even in high temperature, such as wood building materials. Level B3: As long as the flammable building materials meet the source of fire or high temperature, it will break out fire. Currently, this product doed not sale on the market. So what are the external wall thermal insulation fireproofing materials? According to several grades, I will give you some specifical examples. Level A insulation material: Glass wool, foam glass, foam cement, hole-closed perlite, rock wool; level B1 : Extruded polystyrene board through special processing, referred to xps. The other is polyurethane through special treatment, referred to pu. In addition, there are phenolic aldehyde and gelatine powder polyphenyl granule; level B2: Polyethylene, referred to pe. Molding polystyrene board, referred to as eps.
Q:What are included in wall fireproofing 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.
Q:Does anyone know what is the use of waste refractory materials?
Waste refractory materials can be 1, Recycled to do the aggregate and powder of castable , or make bricks. 2, can be reused after smash.3, Metal silicon is an anti oxidant in refractory material, mainly functioning as he oxidation resistance, at the same time improve its toughness.
Q:Who knows about the B-level fireproof insulation materials?
Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
Q:Which industry does the metallurgy and thermal insulating and refractory material belong to?
Materials Industry
Q:how long is the fire endurance of plasterboard?
fireproof endurance can reach a maximum of 4hours, suitable for a variety of public buildings firewall, and partitions for public exit passageway, reaching standard level of fireproof. the lightweight partition made of gypsum board and steel stud is mainly for dividing architecture space. Rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees.
Q:Which schools are the best schools in the world for learning knowledge about refractories?
If you search on a worldwide scale, I might say you are ambitious!!! This major becomes an unpopular one and you must have to embark on graduate and PhD to specialize in it provided that you want to go abroad for further study. Wuhan University of Science and Technology may be the best school in this field with its close relatinship with many refractory manufacture factories across the country. Henan University of Science and Technology is also advisable in terms of this major, which probably promise you a job. Other universities in this regard are not quite familiar to me. You raised these questions, which shows that you are a layman to this major or not quite familiar with this major. If you have any questions, you can resort to me if I can.
Q:What do RH and DH stand for in refractories?
DH :An agreement that allows strangers to build shared keys, originally invented by Diffie and Hellman.
