Q:Who know what kind of fire shutter fire rating are there?
Fire resistance rating of the building elements is different due to the different requirements of the construction . Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. That is, if the fire resistance rating is two, also it is possible to use a class a fire door. Hope my answer will help you.
Q:What is the interior fireproof thermal insulation material?
polystyrene foam board, glass fiber spraying, polyurethane foam, thermal insulation system of inorganic wall. Use "DY" inorganic active thermal insulation material, have small thermal conductivity, large heat storage coefficient, better strength and achieve better thermal insulation and energy-saving effect when used in wall . Wall should definitely not crack and hollow because of high temperature in summer. It doesn't crack and shed because it is influenced by stress during heat expansion and cold contraction in cold winter.
Q:what is the grading standards of external wall thermal insulation materials?
external wall thermal insulation materials are divided according to Fire rating: 1, the combustion performance of insulation materials rates A. inorganic fiber spray coating, glass wool, foam glass, foamed ceramic , rock wool, foam cement, obturator perlite 2, the combustion performance of insulation materials rates B1: Extruded polystyrene board (XPS)after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polyphenyl granule.3, combustion performance of insulation material rates B2. Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:Who knows the model of fireproofing materials?
There are many kinds of fireproofing materials, it's hard to discuss it in detail, but i can talk about the PC fireproofing material with you. There are various models of PC fireproofing materials, the materials manufacturer usually used are common materials; it's divided into the following levels according to fire rating: UL94 VO level, UL94V1, general products can reach V2 level. hope it can help you.
Q:For refractory knowledge. What is the ratio of clay ramming mass?
Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK
Q:How to hang the suspended brick in the refractory masonry?
First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.
Q:what's the classification of fireproof materials?
Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof panel, fire door, fireproofing glass, fire retardant coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
Q:What are the main materials in concrete fireproofing material?
fireproofing materials mainly consist of class A incombustible material and class B1 nonflammable material. Class A incombustible material: Granite, marble, terrazzo, cement products, concrete products, gypsum board, lime products, clay products, glass, tiles, mosaics, steel, aluminum, copper alloy; class B1 nonflammable material: Ceiling materials, dry wall, fibrous plaster.
Q:What is the fireproofing requirements of external wall thermal insulation materials?
External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set 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 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials 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.
Q:how long is the fire endurance of plasterboard?
Plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. Plaster board mounted on steel stud can be used as A level decoration materials. In accordance with the national fire safety rules on fire durance of walls and ceilings and other components, we can not simply say whether a piece of gypsum board can meet the requirements. In GB "gypsum board" it clearly states: Fireproof plasterboard can endure fire longer than 20minutes. Wherein Dragon brand fire-resistant gypsum board can endure fire longer than 40 mintues. Gypsum board is comprised of dry wall, steel stud and various auxiliary materials. the fireproof performance of the gypsum board system is relevant to the type, quality , layers of the gypsum board, quality of keel and installations, whether the rock wool is filled and its unit weight, the treatment of seaming and some minor joints.
