Q:What kind of refractory bricks material is best?
It depends on your purposes. In general, aluminous fireclay brick is usually used. GB/T 3994-2005 insulating fireclay brick. Bricks with good textile are as follows: high-grade thermal insulation refractory brick, GB/T 3995-2006 high alumina thermal insulation refractory brick. Model is A13, and the texture is aluminium oxide. A13 50u, high grade heat insulating brick B5; intermediate heat insulating brick B2, etc.
Q:what grades are fire resistance of fireproofing glass divided into?
Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting roof,ceiling screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements.
Q:What are the chemical composition of refractory cement?
Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
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:Which manufacturers have the best fire-proof materials with light weight?
It now appears that asbestos is the best among the most common fireproof materials. But asbestos also has great harm, especially to lung. Shanghai Xinlong Fireproofing Material Co., Ltd. and Hubei Boyue Lightweight Material Co., Ltd. were established in 2009. The company is located in Wuhan Biological New Town and covers an area of ​​30 acres. The company is a specialized enterprise which is mainly engaged in the research and development, production, sale and construction of lightweight partition board, lightweight fireproof wall panel and lightweight wall panel. The two companies are both good.
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:Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material.
Q:How many kinds of fireproof materials are there in the market?
Inorganic insulation materials basically can achieve the goal, such as glass wool, rock wool, and foam glass. The phenolic foam in the organic foam material is special. Phenolic foam is not only good at insulation, but also good at compounding with steel and other materials to achieve A-level performance, and the A-level insulation materials are: rock(ore) wool, foam glass and inorganic thermal insulation mortar. Insulation materials with B1 combustibility mainly are: Phenolics, polystyrene granules, etc. The insulation materials of fire barrier zone can use such A-level materials as rock (ore) wool, foam glass, and inorganic thermal insulation mortar, etc.
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's the classification of fireproof materials?
Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof panel, fire door, fireproofing glass, fire retardant coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
