refractory grade size 1-3mm calcined bauxite

1. Calcined Bauxite 1-3mm brief introduction:

Calcined bauxite is a mixture of minerals that contain various concentrations of hydrated

aluminum oxides as well as impurities. The primary ore minerals are gibbsite (alumina tri-hydrate), boehmite and diaspore (alumina monohydrates).

Q: What are the fire endurance requirements of class A fire resistant door ?: The fire endurance of class A fire resistance door is 1.5H, but also depends on the product quality. The filling material of class A, B, C fire doors is the same, new fireproofing material-- perlite. The difference is their thickness. The general structure is: surface panel, fireproof?board framework (filled with perlite) fireproof?board panel. !

Q: Can someone professionally introduce the classifications of refractories?: It can be divided into two categories of ordinary and special refractory. Ordinary refractories can be devided into acidic, neutral and alkalinee refractories according to chemical properties. Special refractory can be devided into high temperature oxide, refractory compounds and high-temperature composite materials according to the compositions. Furthermore, it canbe devided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and super refractory products (above 2000 ℃) according to the strength of refractoriness. It can be divided into bulks (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and Indefinite shape (refractory clay, castableand ramming mass, etc.) according to the shapes of products. According to the sintering process, it can be divided into sintered products, cast products, melting jetting products.

Q: How much is refractory spraying coatings?: This depends on whether you use the thin coatin or thick coating. Then it depends whether you use an aqueous coating or oily one. Usually thick aqueous coating is 2-3 dollars per kilogram. While the thin is six or seven dollars per kilogram. The oily coating is more than ten dollars. The prices obtained from the Internet is for reference only.

Q: How long can gypsum board endure fire?: Fire endurance refers to the fire-resistent limit of the whole system of light-gauge steel structure coupled with gypsum. It does nor merely refers to gypsum board. Fire endurance of the common gypsum board with the thickness of 9.5mm keeps 1.5 hours. Those gypsum board with the thickness of 12mm has a fire endurance of 3 hours.

Q: Who knows what is the external wall thermal insulation materials for level A fireproofing?: In general, external wall thermal insulation materials can be divided into level A and level B by combustion grading. Level A is non-combustible material, and level B is combustible materials. A few years ago, the fire of the CCTV Building and Shenyang Hotel put the blame on the level B material. At present, the level A material is widely used, and the prices of same level A materials may be even cheaper than the level B material. Level A material is generally divided into thermal?mortar, phenolic foam board, rock wool board and foam cement board. I hope this information can be helpful to you. Hope you adopt.

Q: How to make fire resistant materials for building stoves: Legend of the old version has been upgraded, or can not enter the server, is not legend stopped?

Q: Which kind of furnace hearth refractory is better?: hearth selected material] hearth material must be durable, high temperature resistant, general selecting masnory made of refractory cement, silicon carbide refractory products, mullite or multicrystal mullite (which is the general term of minerals composed of a series of aluminum silicate, mullite is only stable binary compound in the Al2O3-SiO2 system) etc.. [hearth] is a three-dimensional space surrounded by furnace walls for combustion of the fuel. The funtion of hearth is to ensure the fuel to burn as far as possible, and to cool the gas temperature of the hearth exit to the allowed temperature of convection heating surface safe operation . Therefore, the hearth should have sufficient space and adequate heating surface. In addition, there should be reasonable shape and size in order to fit the burner and the organize aerodynamic field inside the furnace to prevent the flame from adherence, dashing walls and have high fullness and eve wall thermal load.

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: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.: What thermal equipment? The most simple principle is durable, low cost and with no environmental pollution.

Q: What types does soft fire prevention materials have?: Types of fire resistant species. Mainly listed as follows: 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. Indicators of judging fire mainly include: difficult to fire, ignition, smoke toxicity, smoke density, heat release and flue gas; fireproof performance, combustion performance and combustion heat value, fire resistance, high temperature resistance, fire rating, etc. And some specific parameter is needed to use professional testing instrument to judge, but to the inorganic lab for understanding, fire prevention level test result accuracy.
