Q:What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
A level fire resistant steel structure building steel column cannot be constructed with super thin steel structure fire retardant coating, because the ultra thin steel structure fire retardant limit is less than 3 hours. Thin fire retardant coating for steel structure is water borne fireproof coatings painted on the surface of steel structure. It will form carbonized fireproof heat insulation protective layer to insulate oxygen and delay the speed of heating steel structure when it catches on fire, avioding the rapid temperature rise of steel structure and increasing its fire resistant limit. Fire resistance performance: The 2mm coating ≥ 60min, 3mm 100min.
Q:What level is the rock wool board fireproofing material ?
The fire rating classification is a provision for all insulation materials, rather than to separately divide rock wool. Determine the value of the material fire rating according to the relevant test items of 8624. As the rock wool is made from basalt fusion, so it is the level A non-combustible material.
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
Keypoints; 1, curtain wall design must consider the safety requirements, one of which is fire protection design. 2, Generally, fire protection planning between curtain walls should use the method of setting fireproof isolation layer. 3, Two layers of fireproof isolation layer whose thickness should not be less than 100mm respectively on the top edge and lower edge of the material parts of the house. 4, the fireproof isolation layer commonly uses 1.5mm thick galvanized steel sheet as supporting plate, using for shelving fireproof sheet. The 100mm thick cavity between the layers is filled with mineral wool non-combustible materials tightly covered with tinfoil on the surfaces. 5, protective isolation layer should try to reconcile curtain wall beam level and finish floor level, so as to fill non-combustible material and to avoid that a piece of glass acrosses two fire compartments. 6, the beam should be inside 100mm thick fireproof isolation layer to protect the beam and the upper curtain wall plate. 7, when there are open fire function areas like large-scale hotel or restaurant kitchen inside the curtain walls, curtain wall glass in these parts should consider using cesium potassium fireproof glass to improve the fireproof rating in the region. 8, Fireproof setting in the around areas of curtain wall can use the same method of the above fireproof setting between layers. The joint parts of fireproof isolaton layer and main part as well as curtain wall should use fireproof sealant to seal.
Q:Does the production of refractory belong to advanced technology?
Refractories belong to the area of new materials which is one of the eight areas that are supported by the state. Whether it can be declared as high-tech enterprises or not depends on the intellectual property, personnel and finance of the company.
Q:Which fireproofing materials factory is the best in Xiangyang?
Xiangyang Tianhua Fireproof Materials Co., Ltd. has a variety of products with complete specifications. The products include fireproof cable tray, fire resistant groove, fire-resistant shield, ATD-AB, organic fire-proof caulking, intumescent fireproof pillow, fire retardant module, cable refractory coating, ultra-thin fireproof coatings for steel structure and other products. All products have passed the relevant tests and inspections, all performance indexes are in full compliance with national or industrial standards, and meet the technical requirements of cable fireproofing. Xiangyang Weicheng Fireproof Materials Co., Ltd. is specialized in research and development of fire-fighting apparatus and fire retardant materials! It's main products: fireproof bag, asbeston, fireproofing mud, and other types of fireproofing materials.
Q:What's the A class fireproof and thermal inuslation matertial for external wall?
First, external wall thermal insulation material: 1. silicate insulation material; 2. glue powder polyphenyl granule; 3. cement cystosepiment with the use of steel wire gauze (polystyrere); 4. extruded sheet; Second, roofing materials: 1. xps extruded sheet; 2. EPS foam board; 3. perlite and perlite brick; 4. vermiculite and vermiculite brick; Third, materials for heating power and air conditioners: polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Fourth, steel structure material: polystyrene, extruded board, polyurethane board, glass cotton lap felt, 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:Development trend of refractories
The foundation of China's refractories industry is still relatively weak, the utilization level of refractory material resources is low, the quality of refractory materials is not high, excess production capacity of ordinary products, the key products of some high-quality high technology content can be produced, but the quality is not stable, and the service life of refractory material consumption compared with foreign advanced level, there is a considerable gap. Therefore, the new trend of tracking foreign refractories science and technology development, carry out and supporting the development and application of advanced and basic theory research, to promote technological innovation of refractory materials, optimizing product structure, industrial structure adjustment, implementation of the strategy of sustainable development, it is very necessary.
Q:What's the difference between refractory metal raceway and fireproof raceway?
In terms of fire protection, fireproof raceway means that it is composed of the material with certain combustion performance and generally made of flame retardant or incombustible material. While for the refractory raceway, according to GA 479-2004 "Fire Resistant Cable Tray", its most important properties are: Fire resistance of the cable tray should meet with the following requirements: The cable tray of I grade fire resistance should keep the working time more than 60min, of II grade fire resistance should keep the working time more than 45min, and of III grade fire resistance should keep the working time more than 30min. Hope this is helpful for you! Thank you.
