Q: What are the characteristics of magnesium fireproof plate
Fire Excellence: Glass magnesium plate is non combustible plate having good fire-resisitance quality. Flame will never burn continuously on it. It does not catch on fire when temperature reach 800 ℃, and will not be lit up at 1200 ℃. The plate, having high-quality keel partition system, is rated as the highest non-combustible level A1 with fire resistance being above 3 hours. It absorbs a lot of heat when fire is burning, delaying rise of ambient temperature. Waterproof and moisture proof: Glass magnesium plate functions steadily whenever weather is dry and cold or humid and damp, not influenced by condensed water drop and moist air. Even air dried after soaked in water for a few days, no deformation, it will not go out of shape, turn soft, or absorb moisture After testing, the board has no water permeability. Light weight and seismic resistance: Low overall plate density of 0.8-1.2g/cm3 reduces the building's load, and the weight of building interior wall by over 60%, and increases the use area by 5-8%. Its lightweight is conducive to anti-seismic, can effectively reduce main cost of foundation and structure. Superior strength: Magnesite has special 5.1.8 phase covered fiberglass cloth and good toughness of plant fiber. Altough glass magnesium fireproof plate is light, it has tight structure, good stability, wood-like toughness, outstanding performance in impact resistance, compressive strength, tensile strength equal rigidity and toughness, with flexural strength up to 322kgf\cm2 (vertical) and 216kgf\cm2 (level of) as well as impact strength of 25MPa.
Q: Does hardware construction materials contain refractory?
refractory includes one kind of building materials. It is a special material and not commonly used.
Q: Who knows about the criteria of fireproof and thermal insulation materials?
The standards of fireproof and thermal insulation material. 1. the height of buildings is greater than or equal to 100 m, the combustion performance of thermal insulation materials should be A-level; 2. the height of buildings is greater than or equal 60 m but less than 100 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in each floor; 3. the height of buildings is greater than or equal to 24 m but less than 60 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every two floors; 4, the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every three floors.
Q: What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
Insulation materials. Thermal insulation material is characterized by thermal insulation, which is one of the four traditional inorganic nonmetallic materials. Fire?retardant material is cahracterized by heat-resistant. Refractory is a kind of materials of resisit high temperature. Fireproof material, which is different from thermal insulation material and refractory, is a synthetic material with some fireproof subtrate added. It is essentially resistant to high temperature.
Q: Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks
Exports should be fumigated outside of South East asia. Pallet packing is the most common, convenient and inexpensive.
Q: Where is refractory used? Thank you!
Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.
Q: Does anyone know what is a lightweight refractory material?
I am ignorant of this!!
Q: What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
Sodium silicate, pure calcium aluminate cement, boric acid
Q: Does anyone knows which company produces the better refractory materials?
A:Building Materials Company of Guangzhou: Near the Baiyun District, Baiyun District, Guangzhou Road, North Road. B:Guangzhou Research & Development Co., ltd.: Liwan District Fengyuan road No.90 in Guangzhou City C: Huitailong decoration materials Co., Ltd.:the 30th floor of No. 111 Pacific Center, Taikang Road, Yuexiu District Guangzhou City D:Guangdong metal materials company: Near Qishan Road, Tianhe District , Guangzhou city.
