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.

- Q: How many hours of the fire endurance time of the rock wool laminboard?
- Limit is usually two hours. Pay attention to it please.
- Q: How to do environmental impact assessment for refractory Co., Ltd.
- 1, first of all, the EIA unit and the construction party signed the EIA contract. The contract is only legally valid. Generally speaking, the contract will indicate that the first payment has been received before the work begins.2. Collecting information. This is a very important link in the EIA, which is directly related to the quality of the eia. There is a great variety of data,Generally, the construction party will write a list of environmental impact assessment information.
- Q: What a blast furnace refractories generally?
- Common refractories often use silica?brick, semi-silica brick, fireclay brick, high alumina brick, magnesia brick, etc. special materials often used are AZS brick, corundum brick, directly bonded magnesia-chrome brick, carborundum brick, silicon nitride bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide refractory insulating refractory frequently used. material diatomite products, asbestos products, insulation boards. monolithic refractories have fettling frequently used, refractory ramming mixes, refractory castable, fire-resistant plastic, refractory clay, refractory gunning refractory projection material, refractory coatings, lightweight refractory castable, stemming etc.
- Q: What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
- The refractory material is capable of withstanding high temperature burning, while fireproofing material is to prevent burning. They are different from each other
- Q: What does the function of SiC for refractories?
- Anti-acid corrosion anti-skinning
- Q: What are grade classifications of the external walls for fireproofing?
- The classfication of external wall material fire rating is as follows: Level A: Complete retardant building materials may not occur combustion, and the cost is relatively high, home decoration do not need such a high standard. In general, it can be used in the arms powerhouse and electrical appliance store. Level B1: non-flamble construction material has high flame-retardant, it will not be burn under the conditions of open fire and high temperature, but if it is attacked by these two conditions, it may still be burning. However, when the source of fire is transfered, it will be immediately extinguished. Level B2: Combustible building?materials have a certain degree of flame resistance, but the effect is very little. Under the condition of sufficient air, it will break out fire even in high temperature, such as wood building materials. Level B3: As long as the flammable building materials meet the source of fire or high temperature, it will break out fire. Currently, this product doed not sale on the market. So what are the external wall thermal insulation fireproofing materials? According to several grades, I will give you some specifical examples. Level A insulation material: Glass wool, foam glass, foam cement, hole-closed perlite, rock wool; level B1 : Extruded polystyrene board through special processing, referred to xps. The other is polyurethane through special treatment, referred to pu. In addition, there are phenolic aldehyde and gelatine powder polyphenyl granule; level B2: Polyethylene, referred to pe. Molding polystyrene board, referred to as eps.
- Q: What are the technical requirements for refractories?
- To put it simply, physical indicators are pores, volume density, pressure resistance, slag resistance, thermal shock resistance, foot expansion coefficient, thermal conductivity, oxidation resistance and so on. If it is castable, the indicators are mobility, water rate, setting time, and anti bending strength. If it is coating mix, the bonding strength should be checked. Chemical indicators are loss of ignition and the content of aluminum, magnesium, silicon, calcium, chromium, titanium and carbon.
- Q: Who knows how many kinds of fireproof insulation materials are there in the market?
- The so-called A-level materials in fire insulation materials, namely, the WW non-combustible insulation materials, and the WW material s are A-level. Inorganic fireproof and thermal insulation materials can be used as wall insulation materials to replace red bricks, therefore, they, as thermal and cold insulation materials, can reduce the thickness of walls, and save energy, as well as expand applicable areas indirectly, decreased structure weight. They are very good.
- Q: How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.
- Generally how can do high-temperature performance to measure how much liquid may affect hot bending strength rul refractoriness levels of high temperature creep?
- Q: Pals who know something about fire resistant material please tell me how many types of refractory material there are
- There are a variety of refractory materials, each of different use. It is necessary to make resonable classification for refractory materials so as to facilitate scientific research, rational selection and management. There are many kinds of classification methods for refractory materials, including classification based on chemical property, chemical mineral composition, production process, material form and other methods. 1, according to the capacity of fire resistance: ordinary refractory materials: 1580 degrees C ~1770 C Advanced Refractory Materials: 1770 degrees ~2000 degrees c: Classification according to product shape and size: standard 230mm×113mm×65mm no more than 4 scales
