Product Description

 

Bauxite is earthy mineral which consists mainly of Al2O3 , a kind of hydrated alumina containing impurities. According to the usage, It can be divided into the levels of Metallurgy, chemical industry, grinding, cement, and refractory. Clinker is pale yellow and dark grey. It is mainly used for high aluminum refractory material, and also can be used to make the fused corundum. Our materials of calcined bauxite is mainly D-K Style Bauxite Ore.

Q:Can the teflon material resist fire?
It is belonged to the fire retardant materials. By UL-V0 grade
Q:Where do China and foreign countries do more refractory materials?
The domestic production of refractory materials base in Henan Xinmi, Xinmi has a lot of production of refractory material factory, Zhengzhou gold refractories plant is relatively large, there is a need to go to visit the factory.
Q:Refractory material, refractory brick
1, according to the degree of refractoriness:Ordinary refractory material: 1580 ~ 1770 DEG CAdvanced refractory material: 1770 ~ 2000 DEG CSuperfine refractory material: >2000 DEG C2, depending on the shape and size of the product:Standard type: 230mm * 113mm * 65mm;No more than 4 measurements, (size ratio) Max:Min<4:1;Profile: no more than 2 concave, (size ratio) Max:Min<6:1;Or an acute angle of 50~70 degrees;Specific type: (size ratio) Max:Min<8:1;Or not more than 4 or a sharp angle; 30 ~ 50 degrees;Special products: crucibles, vessels, tubes, etc.3, according to manufacturing methods, refractory materials can be divided into:Fired products, unfired products, unshaped refractories4. classification according to the chemical properties of materials:Acid refractory material, neutral refractory material, basic refractory material
Q:How to choose refractory material
Refractory fiber according to different raw materials, there are aluminum silicate, quartz, alumina and graphite, refractory fiber. Commonly used aluminosilicate refractory glass fiber is amorphous, including ordinary aluminum silicate fiber, high-purity aluminum silicate fiber, chromium silicate fiber, long-term use temperature of 1000-1200 degrees.
Q:What brands are the best in the A-level refractory materials?
1 International (It is a well-known brand in the field of global boats and protective coatings, the products are famous for its safety, strength and smoothness, Akzo Nobel (China) Investment Co., Ltd.) 2 LANLING (It is a high-tech enterprise, and a large provider of industrial coatings, started in 1980, as well as a famous brand of Jiangsu Province, Jiangsu Lanling Chemical Group Co., Ltd.) 3 Champion (It is a high-tech enterprise who is involved in developing a number of industry standards, it is a industry-leading brand brand of Jiangsu Province Jiangsu champion coating Technology Group Limited)
Q:how to classify Insulating Refractory ?
General materials have test reports, where fire rating is labled.
Q:What needs to be paid attention to in the construction of high- temperature refractory mortar?
In the construction of high-temperature refractory mortar, the following matters should be noted: 1. Take out the organic fire blocking material and knead it into tha shape of a ball. If the temperature is too low, the blocking material along with the package can be put into 40-70℃ warm water and heated before any other operation. 2. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 3. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 4. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting. The holes should be cleaned up before plugging. Lay, embed, and fill the blocking material into the gap of holes evenly. For larger holes, flame screen can be used as the framework to increase strength.
Q:How to classify the grade of wall fireproof and thermal inuslation matertial?
External wall thermal insulation materials are mainly divided into grade A, grade B1, grade B2 and grade B3. In accordance with the current "Combustion Performance Classification Method of Building Materials", grade A thermal insulation material is incombustible material and belongs to inorganic heat preservation material. However, grade A thermal insulation material is few in terms of the current market. There are only JETCO YT inorganic active wall thermal insulation material, glass wool, rock wool board, foam glass, vitrified micro bead and grade A fireproofing thermal insulation board. However, compared with grade A thermal insulation material, the more welcomed by the market is the organic insulation materials. Thermal insulation material that is determined as grade B is divided into three levels. Grade B1 is grade is flame retardant. Grade B2 is combustible. Grade B3 is flammable.
Q:what's the varieties of fire-proof sealing material?
ATD-AB, organic fire-proof caulking, fire retardant bag, fire retardant net, fire retardant ring, fire barrier wrap, fireproofing sealing strip, flexibility fireproofing coiled material, fireproof glue, etc., fireproofing sealing materials currently on the market can be divided into two types, one is the traditional type: flexible organic caulking, WXY-II, fire retardant bag, fire bulkhead, cable refractory coating; there are some new materials used in large-scale projects: fireproofing coating board system (fireproofing coating board, intumescent fireproof sealing tape, elastic fireproof sealant, Waterborne Fire-retardant Coating), fire retardant module system (fire retardant module, sealing gum, cable refractory coating), fireproofing plaster system (fireproofing plaster, sealing gum, cable refractory coating).
Q:what's the fire endurance of fireproof panel?
fire endurance of fireproof panel can reach 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
