Product Description
Mingyue Bauxite and Calcined Bauxite:
Mingyue Bauxite, ie. bauxite ore, whose main content is Aluminium oxide with, who is department of hydrated
alumina containing impurities in appearance of earthy mineral;
Mingyue Calcined Bauxite is burnt bauxite, who is used for producing the existing uneven materin in nature --
alumina and aluminium. The purpose of calcining bauxite is to remove crystal water and improve the content of alumina.

- Q: Who knows about the fire endurance of A grade fireproofing glass doors?
- The fire endurance of A grade fireproofing glass doors should be no less than 3 hours. A grade fireproofing glass doors use common glass of 6 mm. The shock resistance of float glass is about less than 5 min, and that of toughened glass is about 15 to 30 min. Fireproofing glass is classified in accordance with fire rating, the fire endurance of which is usually from 30 to120min, and that of the most common fireproofing glass is 60 to 90min, but now the market is a mixed bag, the so-called fireproofing glass is generally fake ultra-strong tempered glass. Therefore, you should buy the genuine glass with formal certificates, or you will bring yourself great inconvenience, and even more serious consequences.
- Q: Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!
- There are a lot of silicon manganese alloy manufacturers, production market is relatively large, the manganese content in manganese alloys between 63 to 70 or more common
- Q: What's the feature of construction external wall fireproof and thermal inuslation matertial?
- It has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Its heat conductivity coefficient at normal temperature is 0.018W / (K · m) . The thermal insulation property is three to eight times that of the traditional materials. And it is completely waterproof. [2] Thermal insulation lining has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Light, generally about10-96kg / m3, 20kg / m3 or less is felt, 24-48kg / m3 is middle-hard plate, 48-96kg / m3 is hard plate, wherein 48kg / m? can be used as ceiling, with softening point being 500 ° C , thermal insulation 300 ° C. It is widely used in the United States, k =0.9. Calcium silicate thermal insulation product is developed in 1970s in China. With high compressive?strength, low heat conductivity coefficient, recycle and easily construction, it is widely used in the power system. In China, small workshop?production were the most common, then four production lines were gradually introduced from America, including instant fiber forming, dry method punched felt, which are advanced and quality, temperature endurance up to 800-1250 ° C.
- Q: I know which material is the fire resistance rolling shutter door
- Inorganic fiber cloth as curtain side replace steel fire shutter curtain of steel plate, the thickness of the inorganic fiber cloth is much thinner than the steel curtain plate and the density is very small, so the volume of the same area of ??the inorganic fiber is super fire shutter the same area of ??steel fire shutter half, and weighs only one more out of the same area a few steel fire shutter, however, the inorganic fiber super fire shutter fire but has a very good insulation properties. I hope my answers are helpful to you.
- Q: About the market issues of thermal insulation material and refractory material.
- After all, most people have the characteristics of being accustomed with something and it will not change easily ; second, the South has few material manufacturer, but in the Northeast, there are thermal insulating and refractory material manufacturers, which is in shortage, however, but irt is in the minority, and in many areas it is not suitable for exploitation of mineral (due to heavy industry and agriculture land and other reasons). I hope that my answer will help you. first, in the Northeast, the refractory material is not very rich, but the thermal insulating and refractory material demand is very large; third; fourth, which material is used more relived, after all, we should take the transportation costs into account, and it will depend on the kilns construction engineers being willing to use which kind of material, and the thermal insulation material procurement in northeastern region is mostly from the north.
- Q: Is there requirement for radiation indicator in refractory?
- All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
- Q: Who knows what kind of fire prevention materials are there?
- 1, Fire-proof board Fire-proof board is the most frequently used materials in the market. There are two kinds of fireproof boards which are commonly used; one is the high pressure decorative board, which has the advantages of fire prevention, damp proof, abrasion resistance, oil resistance, easy cleaning, and more variety of colors and designs. The other one is a glass magnesium fire board, the outer layer of which is a decorative material, the inner layer of which is a mineral glass magnesium fire material. It can resist 1500-degrees high temperature, but not suit for decoration. The installation of fireproof ceiling in the exit passageway, stair well and corridor can ensure safety evacuation, and protect people from the spread of the fire. 2 Fire-proof door Fireproof door is divided into wooden fire proof door, steel fire proof door and stainless steel fire proof door. Usually the fire proof door is used for the opening of the firewall, the entrance to the staircase, the evacuation of the aisle, the openings of the pipeline and other parts of the building, and it has an important role in fire separation and reducing the loss from fire. 2 Fire resisting shutter I hope it may be helpful to you.
- Q: What's the classification of refractory material?
- Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome
- Q: What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
- It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.
- Q: How many external wall thermal insulation fireproof material are there
- Class A exterior wall insulation: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic foam, foam glass
