- Q: What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?
- Refractory concrete generally divided into three categories: lightweight concrete (used in insulation); refractory concrete (for refractory temperature requirements are not very high position, and can withstand a certain air scour); heavy refractory concrete (flow with higher requirements for refractory temperature parts, and can withstand a certain intensity). Mainly depends on the design temperature and the use of parts.
- Q: What are the qualifications of refractory industry?
- 1 business license 2 tax registration certificate 3 organizing institution bar code 4 production permit
- Q: Who can tell me about the foundry refractory materials?
- Such as: neutral, alkalic, acidic refractories. Of course, the raw materials of different materials are not the same. Such as: the magnesia-carbon bricks, basic refractory materials: magnesite(electric?smelting, high-purity)+ crystalline flake graphite+ phenolic resin+ additive (aluminate or silicon powder or silicon carbide powder or high-temperature pitch) and so on.
- Q: How many hours of the fire endurance time of the rock wool laminboard?
- Hello. The fire endurance now on the market is generally about two hours. The 50mm color steel sandwich version of Bo magnesium rock wool, with refractory time being five or six hours, is very good.
- Q: What are the characteristics of magnesium fireproof plate
- Plate glass magnesium fire with high temperatures, flame retardant, sound absorption, shock-proof, pest control, anti-corrosion, non-toxic tasteless non-polluting, can be used directly on the painting, direct veneers, available gas nail directly on the tile, the surface has good coloring , high strength, resistance to bending toughness, nails, saw, can be sticky, easy decoration. It can also be made into thermal insulation materials with a variety of compround composite insulation plate.
- Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.
- Classify according to the structure, fireproof?performance and fire endurance of fireproofing glass. Classify according to the structure: Composite fireproofing glass (FFB) and monolithic fireproofing glass, classify according to fire resistance: thermal insulation fire-resistant glass(class A) and non-thermal insulation fire-resistant glass (class C);classify it into 5 levels according to fire endurance: 0.5 h, 1.00 h,1.50h, 2.00h, 3.00h.
- 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 to make the service life of refractory materials longer?
- Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
- Q: What are fire resistant level standards of class A fire resistant door?
- Executive standard: GB12955-2008 Fire Door. Fire resistant level: Class A: 1.5h, B:1.0 h, C: 0.5 h. Thickness of door leaf: Class A: 50mm, B 45mm, C 40mm. Doorframe Specification: Class A, B, C. Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and bright, double open with glass and bright, with a bright picture, Zimu glass Zimu glass with light. Doorframe Specification: Class A, B, Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and brightness, double open with glass and brightness, double open with a lager door leaf and a smaller door leaf, double open with a lager door leaf and a smaller door leaf with glass, double open with a lager door leaf and a smaller door leaf with glass and brightness. Standard sizes: In line with GB5824-86 Hole Size of Building Doors and Windows."
- Q: How long is the fire endurance of fire resistant rolling shutter door?
- According to fire endurance, fire doors can be divided into Class A, Class B and Class C fire doors, whose fire resistance should be no less than 1.20h, 0.90h and 0.60h respectively. You can use fire resisting shutters to seperate fire?compartments in places where it is difficult to set firewalls. When using the fire resisting shutter with unexposed surface temperature rise as fire endurance conditions, its fire endurance should be no less than 3h. But when using the fire resisting shutter without unexposed surface temperature rise as fire endurance conditions, you should set independent protection of closed automatic water spray system at two sides of the shutter, and the duration of water spraying should be no less than 3.0h. I hope it's useful.
