- Q: How about the prospect of refractory material?
- Area depends the market. Resource-based industry
- Q: What are included in wall fireproofing material?
- Wall fireproofing materials include dry wall and gypsum block. Dry wall is made into board material through process by using building plaster as main material, adding an appropriate amount of additive and fiber to make board core and using tailor-made board paper as protection surface. Dry wall ia characterized by light weight, sound insulation, heat insulation, strong processing performance and easy construction method. Gupsum block is lightweight building plaster product made by using building plaster as main raw material, adding water, stirring, moulding by casting and drying. Fiber reinforced material or lightweight?aggregate are allowed to add during the production and foaming?agent can also be added. It is soundproof, fireproof, convenient to construct and many other advantages. It is a kind of new wall material with low carbon, environmental protection, health and in line with the development requirements of the times.
- Q: How to distinguish the construction fire-proof material rating?
- Each country has its own fireproof standards, so I do not know which country you are in ? Each country has different division levels of fireproof materials, such as GB 8624, German standard DIN 4102-1, British standard BS 476, France standard NF P92-501 and so on. GB 8624 Chinese building materials and products combustion performance division levels fireproof resources network (FireTC.
- Q: What kinds of refractory will be used in kiln of sintering ceramics?
- High alumina brick, clay brick, insulating brick and silicon carbide plate.
- Q: How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
- From the perspective of appearances, grade A is 70mm, B 50mm. Their materials are the same .
- Q: What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
- According to the "code for fire protection design of tall buildings", the fire resistance time of the component is at the first level: 3 hours, beam: 2 hours, floor: 1.5 hours;if fire resistance level is level the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. For fire resistant coating, fire resistance time for ultra-thin fire retardant coating is shorter than 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be used. Steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board. As is known to all, steel structure usually will lose bearing capacity usually in 450 to 650 degree, leading to deformation, steel column and beam bending, and be no longer usable at last. Generally fire resistant limit of unprotected steel stucture is about 15 minutes. 1.5 hours;if fire resistance level is level the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. Steel structure an use surrounding concrete (or masonry), fire retardant coating, fire retardant plate and compround structure to achieve the required refractory limit. Hope my answer will help you.
- Q: What defect does fused cast refractories have ?
- The impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement.
- Q: What are Grade-A waterproof inorganic thermal insulation materials?
- 1. Foam ceramic insulation board Foam ceramic insulation board is made of inorganic ceramic material by high temperature baking and is called ceramic insulation plate for short. 2. Composite cement foaming insulation board With cement, fly-ash and micro-silica, composite cement foaming insulation board is a kind of hole-closed lightweight hydrophobic insulation board made by foaming, maintenance,cuttign and processing. 3. Aerated concrete panel Using lightweight material, silicious material and foaming agent and so on, aerated concrete panel is a lightweight concrete panel made by high pressure steaming. 4. Rock wool board With natural igneous rock as material and thermosetting resin as binder, rock wool board is a panel made by melting in high temperature through centrifugation. I hope it can help you.
- Q: How do refractory materials apply into pyrophyllite?
- When it is sized, add some clinker and after calcination, aggregate will be finished. From: turn to help
