1. Structure of Calcined Bauxite Description

Natural Bauxite of  Bauxite Refractory CNBM in China with Size 1-3mm

Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite; main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. The color is 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

Natural Bauxite of  Bauxite Refractory CNBM in China with Size 1-3mm

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.

Q: What kind of flexible fireproof material is really good?
Flexible waterproof materials mostly are asphalt, linoleum and other organic material, which is also called linoleum coiled material waterproof layer. it uses the linoleum, glass cloth fabric as tire layer coil, using all kinds of cementing material phase of asphalt and so on. Make coil bind on roof structure plate leveling layer to form waterproof layer. Flexible waterproof material has high tensile strength, big elongation and light quality, which is convenient to construct. But it has relatively strict operation technology can resistant penetration and aging resistance than rigid materials, aging. Its life is short. Refers to a kind of waterproof material form relative to the rigid waterproofing materials such as waterproof mortar and waterproof concrete. In the form of its and grassroots attached two categories, it includs waterproof coating and waterproofing materials. According to different paste position of waterproof material, it can be divided into outside waterproof waterproof (outsourcing) and inside waterproof (insourcing waterproof) two kinds. Waterproof coil material must be stuck in the grass-roots that have enough stiffness of the. Before pasting, you should apply leveling layer and waterproof layer should be added protective layer of the outside, and need to make the rotation of the flexible material, the processing of subsequent and head closing, in order to ensure the continuity of the waterproof layer and sealing. In addition, there are all kinds of waterproof material and moistureproof coating material.
Q: Can anyone tell me what is A-leve fireproof material?
What you say is probably palstic! B-level means the fireproof rating is at B1-level because palstic material doesn't belong to fireproof materials. It only is fire?retardant. When wholesaling all kinds of insulation materials and construction, it need tos look at the names. B1-level refers to the fire endurance rating of the fireproof material, which is determined according to the fire resistance of the material. In addition, different parts of the material have different fire endurance ratings! You can download a "Specifications of Fireproof Design for Buildings" for further information!
Q: How long usually will the A-level fireproof materials prevent the flame?
The classification of A-level materials is based on GB8624 - 2006 building materials and products combustion performance of grading method. Specific technical requirements are: 1, temperature ≤30 degrees; mass loss rate ≤50%; continuous burning time is 0; 2, the gross calorific value of main components, overall products, external non-substantial components ≤2.0MJ / kg; any internal non-substantial component ≤1.4MJ / kg;
Q: what are the requirements of fireproofing material?
The producing process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into the solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.
Q: Which refractory quality inspection authority is good?
Of course, it is Research Institue of Refractory Materials in Luoyang, Henan. In fact, what we want is accuracy and authority. Quality and inspection costs, which is more important?
Q: What antioxidant will be used in refractories?
Antioxidants (Antioxidants) is the material to prevent bad influence of oxygen. It is a kind of material that can help to capture and neutralize free radicals, the category of material to remove free radicals damage to human body. Some of the body's antioxidant is self-synthesis, others is also from the food supply. Strong antioxidant such as ASTA (short for astaxanthin), etc., generally human cannot synthesize and it must be intaked from food. (1)antioxidants in the food can protect food from oxidative damage and deterioration. (2) it has the antioxidant effect in the human body's digestive tract and prevent oxidative damage in the digestive tract. (3) after being absorped, it can play a role in other body tissues and organs. (4)It is derived from certain foods that have antioxidant effect of extract and can be used as a treatment drug. Antioxidant mechanism includs chelated metal ion, scavenging free radicals, quenching singlet oxygen and removal of oxygen and inhibit oxidase activity, etc
Q: What things and cement mixed can act as refractory?
Cement building, portland cement, refractory grade, calcium aluminate. Cement acts as refractory need to use calcium aluminate cement.
Q: What is the fire endurance of fireproof glass cotton?
Good thermal insulation and thermal insulation. thermal insulation and thermal insulation depends on the heat conductivity coefficient of glass?silk λ=0.043W/m2K. good fireproof?performance, it's fire-resistant capacity is more than 1000 ℃.
Q: What types does soft fire prevention materials have?
Soft type fire resistant species. Finishing fire retardant paint, component fire retardant coating, fire-resistant coating for steel structure and othe kinds of fire retardant coating. Flame retardant plastics and its products, textiles, building materials, flame retardant fabric and exterior wall thermal insulation system products, floor materials, such as various types of fire prevention materials;Fire prevention board, fire doors, fire prevention, fire shutter, fire glass window frame, elevator doors, ventilation pipes, fire blocking material, fire smoke exhaust fan and other kinds of artifacts (resistance) fire prevention.
Q: Fire insulation and fireproof insulation board materials What is the difference in performance?
Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of it. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, Platycodon grandiflorum as the main raw material.
