Q:What kind of flexible fireproof material is really good?
The best one is grade A fireproof material. A-class fire flexible material adopts clay, stone, sand, cement blocks and other inorganic powder and modifier and product density is 2327 kg/m3. Upon examination, the combustion performance of this product is in accordance with the grade A specified requirements and additional classification meets A s2, d0, t0 level requirements. According to GB 8624-2006, the combustion performance of product reach A2 - s2, d0, t0 level.
Q:What are fire resistant level standards of class A fire resistant door?
Executive standard: GB12955-2008 Fire Door. Fire resistant level: Class A: 1.5h, B:1.0 h, C: 0.5 h. Thickness of door leaf: Class A: 50mm, B 45mm, C 40mm. Doorframe Specification: Class A, B, C. Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and bright, double open with glass and bright, with a bright picture, Zimu glass Zimu glass with light. Doorframe Specification: Class A, B, Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and brightness, double open with glass and brightness, double open with a lager door leaf and a smaller door leaf, double open with a lager door leaf and a smaller door leaf with glass, double open with a lager door leaf and a smaller door leaf with glass and brightness. Standard sizes: In line with GB5824-86 Hole Size of Building Doors and Windows."
Q:What kind of material is good for cabinet fireproof board
What kind of material is good for cabinet fireproof board What are the advantages and disadvantages of using it? How much is the price? A about how much does one piece cost?
Q:The fire prevention board line is made of what material?
Crural line: wooden, in the market, there are sjoiner woodblock, peach wood and artificial engraving. The second classification is stone and the most used one is the marble graved or ceramics well-made one is taken as the first choise. Its price is a little bit expensive than the wooden one, but also a suitable choise. Condole supports: It has various category. The general furniture choose plaster and anti-firing plate and the other also have a choice of steel. You can make a suitable choice according to the need. If it is contracting project, it depends on your project specific plan and funds plan. In a word, beauty and harmony should be given priority since it is the source of design.
Q:Which kind of external wall fire barrier zone material is better?
The following types are: rock wool, aerated concrete, phenolic aldehyde and foam cement rock wool fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass fiber mesh and decorative mortar finishing layer or coating. Good air permeability
Q:What's the texture of refractory for the hearth of reverberatory furnace? ?
High alumina brick; you can use zircon brick under the temperature above 1700? ;may i use mullite bricks under the temperature from 1400 to 1700? you can use clay brick and heavy corundum brick under the temperature of below 1400 degrees, question closely: what's the usage temperature of reverberatory furnace? < pre accuse = "qRA" > is there someone use refractory fiber?
Q:How much is the duration of fire resistance of the porous brick shale?
The duration of fire resistance of the porous brick shale could reach 1,580℃—1,770℃. It is predominantly applied in coke oven masonry and building, glasses, porcelains, carbon calciner, and the vault of thermal furnuces of refractory bricks as well as other load-bearing elements, and high temperature bearing parts of cowper stove. But it should be aware that it can’t be used in thermal equipment below 600℃ and with large variation of temperature.
Q:Which are fireproofing external wall materials?
According to combustion performance, external wall thermal insulation materials are classified as Grade-A and Grade-B. Grade-A refers to incombustible material and Grade-B combustible material. A few years ago the fire in CCTV building and Shenyang Hotel were caused by Grade-B material. Currently Grade-A material is more commonly uesd and less expensive than Grade-B material. Grade-A material can be divided into thermal mortar, phenolic foam board, rock wool board, foam cement board, etc. Thermal mortar is easy for construction and unexpensive, but it is also easy for faking due tou its simple procesing. It is recommended to find a large factory whihc has gone through the formalities.
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
Q:What is the principal part of silicious refractory material
blast furnace hot blast stove and ceramic tunnel kiln vault, etc., the softening temperature under a fixed load is high (1690-1710 degree), glass melting furnace, lightweight silica bricks and generally the silicon dioxide is greater than 93% and used above the 600 degree. I had undertaken to complete the 50,000 tons over two advanced silica brick production line design. It is a typical acidic refractory. At present, it is mainly used to coke oven which the masonry operating temperature is higher than 600 degree, with good acid resistance of slag erosion, including silica brick, good thermal conductivity, high thermal vibration stability, product with fused quartz, close to its refractoriness silicious refractory SiO2 which is as the main component of refractory products.
