Product Description:


1.Structure of Calcined Bauxite Description

Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron.  From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle.  Very difficult to melt.  Insoluble in water,  soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material. 


2.Main Features of the Calcined Bauxite

Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum

hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .This removes moisture there.By increasing the alumina content,compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 84%to88%.The heating is carried out in rotary kilns. 

3.Main usage of the Calcined Bauxite

(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry, daily necessities, etc. 
(2) precision casting. Alumina clinker made after the mould precision casting processed into fine powder. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department. 
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong, and good physical properties. 
(4) aluminum silicate refractory fiber. With light weight, high temperature resistance, good thermal stability, low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries. 
(5)  in magnesia and bauxite clinker as raw materials, add the appropriate binder, used for pouring ladle whole ladle lining has particularly good effects. 
(6)   manufacture alumina cement, abrasive materials, ceramic industry and chemical industry can be aluminum of various compound.

Q:How many levels are there in the classification of PP fireproof materials?
PP fireproof materials level V-0: After two 10-second fame tests on the sample, the flame extinguishes within 30 seconds. Inflamer can not drop. V-1: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can not drop. V-2: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can drop.
Q:The fire prevention board line is made of what material?
The line is a kind of composite stainless steel decorative profiles which outer layer is the matte frosted stainless steel plate and inner liningl is wooden material. It do not need to render with fine wood and also need not to buy a stainless steel plate cutting, cutting, bending, such as multi-channel intricate process, processing production. It is convenient to install through the buckle button directly on the booth. When installation, it only needs to be bolt and plug to be fixed on the wallafter blanking cut. compared with the traditional wooden play crural line, the profile is more beautiful and firm, and environmental friendly. And compared with the traditional craft production of stainless steel line, it's cheaper and more convenient to install. This product is not only sitable to decorate in the family, but also is more suitable for the hotel, hotel, office building, and the application of all kinds of public places.

Q:How should fireproof building materials be ranked?
5. Civil building 5.1. Fire resistance rating, number of layers and floorage of civil buildings 5.1.1. Fire resistance rating of civil buildings should be classified into four levels of first, second, third and fourth. Unless otherwise specified in the code, the combustion performance and fire endurance of building components with different fire resistance rating should be no less than that of the regulations in Table 5.1.1. Table 5.1.1: Combustion Performance and Fire Endurance (h) of Building Components (Figure) Note: 1. Unless otherwise specified in the Code, the fire resistance rating of the building with wooden pillars as load-bearing and incombustible material as the building wall should be the fourth level; 2. For the suspended ceiling of the building with the second level of fire resistance rating, if it uses non-combustible component, it won't be limited in its fire endurance; 3. For buildings with the second level of fire resistance rating, if it is really difficult for the partition wall of rooms with the area of no less than 100m2 to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.3h; 4. For buildings with the first or second level of fire resistance rating, if it is really difficult for the partition wall of both sides of the evacuation walk to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.75h. 5. Fire endurance and combustion performance of the residential building component can be implemented in accordance with the provisions of current national standard GB 50368 "Residential Building Code".
Q:What's the B grade fireproofing material?
Grade B: rubber and plastic, extrusion molding, polyphenyl, PEF. organics, extruded sheet, polyphenyl board, phenolic resin. Hairong modules (thermal insulating and fireproof material) can reach grade B1 in fireproof performance.
