Q:What are the raw materials of refractory? And what are their names?
Q:Who can tell me about the foundry refractory materials?
The classification of refractories commonly used in casting and smelting: refractory bricks: siliceous bricks, high alumina bricks, corundum bricks, magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks,etc. shapeless refractory materials: ramming mass, castable refractory, refractory cement, silica sand, magnesite, etc.
Q:How to distinguish the construction fire-proof material rating?
According to national standard GB8624-97,combustion performance of building materials are divided into the following levels: Class A: Incombustible building material: Material that almost never burn. Class B1: Nonflammable building material: Nonflammable materials have good effect of flame resistance. In case of fire it in the air or at high temperature it is difficult to catch fire and spread, and when the fire source is removed, the combustion can stop immediately. Class B2: Combustible building material: Combustible materials have good effect of flame resistance. In case of open fire in the air or at high temperature, it will immediately burst into flames and spread the fire quickly, such as wooden column, timber roof truss, wooden stairs, etc. Class B3: Flammable building material: No flame-retardant effect, highly flammable, high risk of fire. According to national standard, the fire rating of PVC floor must be class B1.
Q:What is the common inorganic fireproof and thermal inuslation matertial?
Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.
Q:What are the insulation fireproofing materials?
Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.
Q:What are the material requirements of class A fire resistant door ?
What are the material requirements of class A fire resistant door ?
Q:Can you tell me the classification of fireproof sealing material.
Organic fireproof sealing material include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. Organic plugging material take organic materials as the adhesive with certain flexibility or plasticity when used. The product is thick liquid or cement. Inorganic plugging material take powder of solid inorganic material as the main ingredients, and admixture mixed use, with proper workability. Fireproof bag apply bag shaped object made up by fire-proof materia to large hole fire plug or cable tray fire compartmentation (fire package also called as refractory package or fire protection package). Fire modules is made up of fireproof material, which is a solid with a certain shape and size and can be easily cut and drilled, suitable for holes or fire-proof sealing of cable tray. fireproof sealing material is the plank made up of fireproof material, which is a solid with a certain shape and size and can be easily cut and drilled, suitable for holes or fire-proof sealing of cable tray. Foam block after injection holes can lathery foam and seal hole. Sealing strip is made of fire prevention materials with certain geometry shape or flexible coil geometry.
Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name, hope you adopt.
Q:What's the A grade fireproofing material?
Main materials are steel, wood, steel and wood. Fire door is one of the measures for buildings fire separation, and it is generally installed at the firewalls, entrances and exits of stairwells or tube well openings, which is required to play the role of fire protection and smoke control. Fire door plays an important role in preventing the spread of smoke and fire and reducing damages, so it must be strictly required. Fire dooor is classified into three classes of A, B, C, and their fire insulation and fire integrity is greater than or equal to the following values: A class fire door: 1.5h; B class fire door: 1.0h; C class fire door: 0.5h. It is in accordance with the provisions of Article in GB12955-2008 "New Standard of Fire Doors".
Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?
Alkali resistant castables cost the least.
