Coating standard: classification standard for fire performance of fire retardant coating for interior decoration of buildings

Core tip: this material standard is only applicable to the fire performance classification of fire retardant coating for interior decoration of buildings 1 nouns and terms 1.1 fire retardant coating: it is a special coating applied to the surface of combustible base material to reduce the burning characteristics of the material surface and block the rapid spread of fire, or to building components to improve the fire resistance of components 1.2 facing fire retardant coating: it is a fire retardant coating applied to the surface of building materials as decoration and flame retardant The film thickness of this coating is generally less than 1mm, usually 0.2-0.4mm 1.3 thick paste fire retardant coating: it is applied to the surface of building components to Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Home of coatings: this material standard is only applicable to the fire performance classification of fire retardant coatings for interior decoration of buildings 1 nouns and terms 1.1 fire retardant coating: it is a special coating applied to the surface of combustible base material to reduce the burning characteristics of the material surface and block the rapid spread of fire, or to building components to improve the fire resistance of components 1.2 facing fire retardant coating: it is a fire retardant coating applied to the surface of building materials as decoration and flame retardant The film thickness of this coating is generally less than 1mm, usually 0.2-0.4mm 1.3 thick paste fire retardant coating: it is a thick layer fire retardant coating applied on the surface of building components to improve the fire resistance of components The coating thickness of this kind of coating is generally more than 1mm 1.4 flame propagation ratio: it is the value measured in accordance with zbg51002-85 test method for fire performance of fire retardant coatings - tunnel combustion method This value is based on the surface flame propagation characteristic data of the tested material when the flame propagation ratio of asbestos board is "0" and that of oak board is "100" 1.5 weight loss: it is the value measured in accordance with zbg51003-85 test method for fire protection performance of fire retardant coatings chamber combustion method, which is a fire resistance performance data (g) based on the difference between the weight of the test plate before and after combustion under the specified coating ratio and the specified combustion conditions 1.6 carbonized volume: another set of data measured according to the test method described in 1.5 This data is a fire resistance data (cm ^ 3) based on the multiplication of the maximum length, maximum width and maximum depth of the substrate carbonized under the specified coating ratio and specified combustion conditions 1.7 the fire resistance time is measured in accordance with zbg51001-85 test method for fire resistance of fire retardant coatings - large plate combustion method This value is expressed by the specified base material, under the specific combustion conditions, the temperature of the back fire surface of the test plate reaches 220 ℃ or the time required for the obvious crack penetration of the test plate (min) 2 General requirements 2.1 as the protective layer and facing material, the fireproof coating shall have the physical and chemical properties required by the object of use 2.2 the fireproof coating shall meet the requirements of Table 1 before testing its fireproof performance Table 1 ┌ -
