- Q: what's the seal of fireproofing material?
- Folded organic putty takes organic material as bond,it has certain flexibility or plasticity while using, and it's products are thick liquid or cement shaped object. Folded WXY-II is powered?solid that takes inorganic materials as main components, it has certain workability while used with admixture. Folded fire retardant bag is the packaged object made by fireproofing material, and it's suitable for fireproofing seal of larger openings or fire separation of cable?bridge(fire retardant bag also refers to fireproof bag) Folded fire retardant module is the solid made by fireproofing material with certain shape and size, and it is easy for cutting and drilling, suitable for fireproofing seal of opening and cable?bridge. Folded seal board is made by fireproofing material, it's easy for cutting and drilling, suitable for fireproofing seal of large opening. Folded foam seal is a kind of fireproofing material that can automatically expand and foam and sealed by opening after injecting the foam into opening. Folded sealing strip is a product or flexibility coiled material mede by fireproofing material with certain geometry shape. Folded sealing gum is a kind of liquid fireproofing material that has a function of fireproofing and sealing. Folded fire retardant bag is soft and windable tape-shaped product made by fireproofing material, it is winded on the external surface of plastic pipe and fixed with steel belt or other proper methods, it's the expansion, squeezing and softening pipe after contacting with fire, opening left by burning or soften of seal plastic pipe. Folded fire retardant ring is the product made by fireproofing material and metal shell, it's covered on the external surface of the plastic pipe, expanding and sealing after contacing with open fire, the opening left by burning and soften of plastic pipe when it passes through the opening of wall and floor.
- Q: How to divide fire rating of decorating materials ?
- The combustion performance of building materials is divided into the following grades by the national standard GB8624-97: level A: incombustible building materials, almost no burning material. Level B1: Flame retardant building materials, such kind of materials are effective in flame retardance. It is difficult to fire in the air in the case of open flame or under high temperature, it is not easy to spread quickly, and when the fire source is removed , the fire stopped immediately. Level B2: combustible building materials. Combustible building materials are effective in flame retardance. It will immediately burst into flames in the air in case of fire or under high temperature, and it is inclined to lead to the spread of fire, such as wooden, wooden frame, beams, wood stairs,etc. Level B3: Flammable building materials: they have no effect in flame retardance, easy to burn, fire risk is very huge.
- Q: Who knows what is the standard of insulation material whose fire proof is level A?
- Level A is distinct from B in coefficient of fire proofing. Level A is non combustible, while Level B is divided into B1( flame retardant), B2(combustible) and B3( inflammable). Currently in the market, level A materials are as follows: phenolic, rock wool, insulation mortar, ceramic foam, foam glass, and foamed concrete. The most advantageous of level A material at present is foamed concrete, also known as foamed cement. Xuzhou Lvchuang Construction company is working on this, you can search fro it on the internet, it has high cost performance.
- Q: What is the difference between wear-resistant material and refractory material?
- One is to require wear-resistance. It can be both fire-resistant and wear-resistant, and they can enter different categories. Faced with different demands, it has a variety of features. But both can also be integrated. I think many materials have same division. One is fire-resistant. The two concepts are different division. They are not comparable.
- Q: What are the requirements of refractory temperature of refractory brick?
- Refractory brick, called refractory?brick for short, is refractory material made by firing refractory clay or other refractory raw materials. Faint?yellow or brownish, it is mainly used in building smelting furnace. It can resist 1,580 ℃ -1,770 ℃ high temperature.
- Q: Who can tell me about the foundry refractory materials?
- The casting fireproof materials can be divided into three categories in accordance with chemical property, namely, acidic, neutral and alkaline refractories. The commonly used refractories are alkaline and neutral ones, such as alkalic magnesia-carbon bricks, fired magnesite bricks, magnesia-chrome bricks, magnesium-calcium bricks, and neutral high alumina bricks, corundum brick, clay bricks, etc. The shapeless ones include: castable refractory, ramming?mass, gunning mix, coating, and dry vibration material, etc!
- Q: The development prospect of fire-resistant material
- Concrete has a broad employment direction while refractory material is not in popular demand. But if you do well, you are one of ethe experts.
- Q: Fire insulation and fireproof insulation board materials What is the difference in performance?
- Fireproof materials and insulation materials, refractories not the same thing, but some insulation materials are fire resistant and refractory. Fireproof material is a synthetic material characteristics of fire resistance or the material itself is a high temperature resistant, flame-retardant. Fireproof materials are mostly used for construction, playing an important role in fireproof today in various forms.
- Q: How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
- The advantages are largest scale, top production amout in the country, accounting for one-third of the national market, having technology, strength and the market. The disadvantages are the lack of mineral resources, serious environmental pollution,
- Q: Which basic refractory is better?
- The following companies are good: 1, Xuzhou Reka Casting Material Co., Ltd. Address: No.22-2 Luoshan Road, Economic and Technological Development Zone, Xuzhou, Jiangsu. 2, Golden Triangle Refractory Plant, Xinmi, Henan.
