Q:What is the difference between the fire rating and the fire resistant level of the fire-fighting equipment?
Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. Fire resistance rating of the building is divided into four levels. Standard of fire resistance rating is determined by the combustion performance and fire resistance of the main housing member. Level one or two are in accordance with the Article 1.0.2 in this specification.
Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
fireproofing glass is mainly control the spread of fire or smoke insulation, and is a measurable fireproofing material, the fireproofing effect is evaluated by the fire resistance. It is through a special process and treatment, and it is a special glass which can maintain its integrity and thermal insulation in the specified fire resistance test. Original glass of fireproofing glass can be used float flat glass, and composite fireproofing glass also can use monolithic fireproofing glass.
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:Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material.
Q:Procedures for producing common refractory materials?
The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.
Q:who knows the technology of fireproofing material?
1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
Q:Which are roofing fireproofing material?
(1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
Q:Which basic refractory is better?
The following companies are good: 1, Xuzhou Reka Casting Material Co., Ltd. Address: No.22-2 Luoshan Road, Economic and Technological Development Zone, Xuzhou, Jiangsu. 2, Golden Triangle Refractory Plant, Xinmi, Henan. Address: Ganzhou Street, Litang Village, Xinmi City, Henan. 3, Zibo Sun Refractories Co., Ltd. Address: Wujia Village, Shangjia Town, Zichuan(Wenchang Lake) District, Zibo City, Shangdong.
Q:Are the rubber insulation materials are refractory materials?
Bushi
Q:Is there anyone who can explain how to grade the level of fire insulation board?
1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
