Q:What are the main materials in concrete fireproofing material?

it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire?retardant?coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )

Q:What are the common refractory insulation cotton material?

I know less about this, I hope the following will help: Fire resistant thermal insulation material mainly refers to inorganic thermal insulation material and compround thermal insulation material. According to the shape can be divided into: Fibrous finishes, slag wool, rock wool, glass wool, aluminum silicate cotton. ceramic fiber, micro pile of diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete etc., foam like bubble glass, volcanic ash glass, foam clay, foaming concrete, paste powder polystyrene particles insulation slurry

Q:Does anyone know the refractory temperature of fire-resistant glass?

Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. If the overall glass is not heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes

Q:What kind of foundry ingot refractory materials are there? Please be more detailed.

Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, etc.

Q:How to divide fire rating of decorating materials ?

Generally speaking, it is divided into Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability.

Q:What is the function of refractory in ceramics?

It depends on what purpose you want to achieve. At the same time, part of special ceramics belongs to refractory. If is is to produce ceramic products, the aforesaid answers are very comprehensive.

Q:Who knows what material is in the center of fireproof rolling curtain?

Material and the type high silica cloth as curtain, side rails, with galvanized steel in its end and stainless steel two kinds of materials with double curtain in the end I hope my answer can help to you

Q:who knows the fire endurance of fireproof coating?

this is not specfied , depending on design requirements. The products we made have fire endurance from 1to 4hours . We have not done any higher.how is the fireproof coating in improving fire resistance of building components? finishing fireproof coating; wood fireproof coating; fire-resistant coating for steel structure, fire-resistant coating for concrete structures, tunnel fire retardant paint, fire retardant paint for the cable. Fire retardant coating is composed of the base materials (that is film forming substance), pigments, ordinary coating additives, fire retardant agent and dispersion medium. In addition to fire retardant agent, other components functions the same as in ordinary coating, but its performance and thickness are specifically required.

Q:How long can gypsum board endure fire?

General gypsum plaster board with a thickness of less than 12mm has a fire endurance which is less than half an hour. Scheme One of gypsum board partition system by using 75# series of lightgage steel joist: separation distance of keels keep 600mm in vertical direction. The thickness is greater than 0.5mm; gypsum board: it shoule be the board of double-sided and single-layer with the thickness of 12mm. Fire-resistant gypsum plaster board's fire-resistance limit: 1 hour. Sound insulation index: over 35 rwdb.

Q:What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?

There are two kinds: 1, the thickness of the plate is between 20 ~ 50 mm with composite structure 2, sheet thickness is between 6 ~ 15 mm calcium silicate fire prevention board.
