Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
As far as I am concerned, polystyrene foam color steel plate cannot be used as decorative fireproofing material. Because polystyrene flame retardant and non-flame retardant of the points, from the fire retardant is generally self-extinguishing. Polystyrene is the polymer synthesized by styrene monomer through free radicals polycondensation reaction. It is a transparent thermoplastic plastic. With above 100 ℃ glass transfering temperature,it is often used to make a variety of disposable container and disposable foam lunch box which have to withstand the boiling water temperature.
Q:What materials are needed to make the amorphous refractory bricks?
Amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive, and can be directly used without high temperature firing.
Q:Who knows the setting requirements of roofing fire barrier zone?
First, the the minimum of fire barrier width is greater than 30cm, and the thickness should be same to the thickness of the insulation materials. Fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. Fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. Second, Fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. The thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Third, When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. Flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. I hope you can be satisfied
Q:what's the varieties of thermal insulation material with A level fire rating?
the main A level fireproof material is rock wool now (note:it is rock wool not mineral wool). A1 level fireproofing, now the largest producer is Taishi rock wool Co., Ltd.; hope my answer can help you, thank you.
Q:The difference between refractory and thermal insulation material
In simple terms, refractoriness is different. The refractoriness of refractory is high while that of insulation material is low.
Q:Current development status of qualitative refractory materials.
Q:Who knows about roof fireproofing materials?
At present, only phenolic foam boards can meet requirements. The test temperature can be 2,000 degrees, and there is no molten droplet during the tests and it can maintain integrity. heat conductivity coefficient: 0.03W / (mk), non-combustible, non-toxic, smokeless!
Q:What are the characteristics of the carbon composite refractories?
The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?
Residential buildings should meet the following requirements: 1, The height of building is greater than or equal to 100m, the combustion performance of thermal insulation material should be level A. 2, The height of building is greater than or equal to 60m but less than 100m, the combustion performance of thermal insulation material should not be less than the level B2. When using the level B2 thermal insulation material, each layer should set a horizontal fire barrier zone. 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 thermal insulation material, each two-layer should set a horizontal fire barrier zone. 4, The height of building is less than 24m, the combustion performance of thermal insulation material should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone. According to this understanding, it can not be set.
Q:What is the difference between wear-resistant material and refractory material?
However, the purity and the requirement are not the same. For example, brown emery is often used in abrasive paper, which doesn't matter. Refractory material uses brown corundum brick. The material used in texture and refractory material of abrasive is different. For example, it is to facilitate their forming and easy sintering. However, some other materials should be added when making brown corundum brick. In general, some top grade materials are used to make abrasive.
