Q: Who knows about the fire endurance of A grade fireproofing glass doors?: The fire endurance of grade A fire resistance rolling shutter doors should be no less than three hours. Fire doors can be divided into A, B and C grades according to their fire endurance which should be no less than 1.20 h, 0.90 h and 0.60h respectively. Places where are difficult to set fire-proof bulkheads can use fire resisting shutters as partitions of fire?compartments. The fire endurance of fire resisting shutters that include unexposed surface temperature rise as judging condition should be no less than 3 h. Fire resisting shutters that exclude unexposed surface temperature rise as judging condition should set up independent protection of closed automatic water spray system on both sides of shutters, and the duration of water spray system should be no less than 3.0 h.

Q: Application of refractory materials in petroleum industry: For example, natural gas transportation, chemicals, equipment, fillers, safety, insulation, and even building materials for housing are available.

Q: How long is the duration of fire resistance that fireproof window of level B can endure?: Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof window. Fireproof window of level A can endure fire for 1.5 hours while level B, 1.2 hours

Q: What's the maximum temperature that the refractory ceramic fiber cloth can endure?: It depends on the composition of the ceramic material. If its composition is alumina and it is used by civilians, its normal use temperature is 1200℃; if its composition is alumina but it is for millitary use, it can endure the highest temperature of 2200℃.

Q: What is the use of refractory?: Some is insulated for personnel safety, some is to save heat loss and conserve energy, and some is used as lining of kilns. Because of its light weight, I recommand it to you and I am engeged in ceramic fiber, just an advertisement.

Q: How to divided the grade of external wall thermal insulation materials?: Synthesized the three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. Please contact Qingdao Shanfang Instrument Co., LTD for details, they specialized in the external wall thermal insulation materials fire?rating test

Q: Can anyone say something about what A-level fire-proof decorative material is?: Combustion performance rates of decoration materials ratess combustion performance of decoration materials A incombustible B1 flame retardancy B2 flammability B3 high flammability The B1 rate combustion performance of gypsum plaster board and mineral wool acoustic panel absorber installed on steel joist can be used as A-level decoration materials. Inorganic decorative coating applied on the A level substrate can be used as A level decoration materials. Hope you adopt

Q: what needs to be noted when choosing and using blast furnace fireproof materials?: Hello,: three parts of the blast furnace lining in general are easily corroded. The first one is furnace bosh,second is the middle part of the furnace, The third is lower part of the furnace stack. if These parts are damaged, then we need an overhaul. Bosh, because damage to the middle part of the furnace and the furnace bosh are generally due to alkali metal and fusant erosion. the main reason for the lower furnace part damage is molten iron, slag. In view of this situation, mullite bricks, corundum bricks, silicon carbide bricks are used for reparation. make repairments as soon as possible if any problems occur in case of incidents.
