Q:What's the feature of construction external wall fireproof and thermal inuslation matertial?
Building external wall fireproof thermal insulation material is made by stirring, casting, foam protecting and cutting with industrial by-product gypsum as the main raw material, adding sulphate aluminium cement, fly-ash, polymer additives and other materials. It has excellent properties of respiratory function , air permeability, water impermeability, recycling system data, wind load resistance, shock resistance, thermal insulation, fireproof and sound insulation.
Q:Who know what kind of fire shutter fire rating are there?
There is no national standard for fire protection performance of fire roller shutter in China, and now the executive standard of GB14102-2005 "fire shutter": F1, fire-resistant time 1.50h; F2, fire-resistant time 2.00h; F3, fire-resistant time 3.00h; F4, fire-resistant time was 4.00h before the national standards of fire shutter grading is introduced, expert advice that fire resistance test be made according to national standard, to reach back fire surface temperature rise requirements, if the refractory limit is greater than or equal to 3.0h, it is said to be super fire shutter, if test not inspect unexposed surface temperature rise as a judgement of the conditions, the door is referred to as ordinary fire shutter doors. I hope my answer can help you
Q:Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.
Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.
Q:What refractory material lead smelting furnace needs?
Q:What are the applications of refractory busway?
Refractory busway is designed for the power supply in fire-fighting equipment, and it can not be used for other purposes. As the generatrix has good heat resistance, thermal insulation, and the heat of the busway can not be emitted, it can not be used long-term at full capacity. In addition to fire-resistant busway, other bus lines can be operated long-term at full load.
Q:How long is the duration of fire resistance of hollow glass magnesium board
Hollow glass magnesium board features fire prevention, waterproof, tasteless, non-toxic, not frozen, not rot, not crack, unchanged, non burning, high strength and light weight, convenient construction, long service life and so on, and it has more characteristics among products of the same kind nationwide. Its fire resistance limit is 0.65℃.
Q:Who can tell me about the foundry refractory materials?
The classification of refractories commonly used in casting and smelting: refractory bricks: siliceous bricks, high alumina bricks, corundum bricks, magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks,etc. shapeless refractory materials: ramming mass, castable refractory, refractory cement, silica sand, magnesite, etc.
Q:How to divide the fire resistant level of construction thermal insulation materials?
How to divide the fire resistant level of construction thermal insulation materials: Combining 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 indexes for specific division, very professional and technical, so it is hard to say clear now. For details, please contact Qingdao Shanfang Instrument Company who is specialized in fire rating tester for external wall thermal insulation materials.
Q:How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
I don't know how it has developed. Its advantage is the coal industry. You have to know the generating capacity in Xinmi thermal power plant first, and then you will know their coal cinder yield, after all, this is the raw material. Xinmi is not far away from Zhengzhou. The real estate in Zhengzhou is still good. I'm not sure about the others.
Q:what is steel fire door made of ?
1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance. 2. Category 1)safety facilities to prevent underground building from fire expansion and control volatilation. It is usually divided into steel and wooden fire door. 2) Class A fire doors, fire endurance of 1.5 hours; B fire doors, fire endurance of 1.0 hours; Class C fire doors, fire endurance of 0.5 hours. 3) In fact, there are many types of fire doors. For example, there are wooden made fire doors glass fire doors and steel fire doors based on different materials. access control fire doors, entrance fire resistance door, interior fire doors, explosionproof and fireproof door, quick-lock fireproof doors, quick opening door encountered with fire and multi-functional fire doors. 4) Based on the installation location: External fire doors and built-in fire doors. 5) divided by technology: Electronic fire doors.
