Brown fused alumina size sand

Product introduction:

The main component of brown fused alumina size sand includes: high quality bauxite, anthracite, scrap iron, its fabrication adopts modern new unique technology. It has short grinding time, high efficiency, good economic returns, low price. Brown fused alumina is superior to other abrasives because it has conchoidal fracture, the edge and corner of this conchoidal are sharp. These edges and corners can form new edge and corner in continuous grinding. The most important characteristics of brown fused alumina are high hardness, high-density,stable chemical

properties and strong self-sharpening. So, it is the best choice for sand blasting process and grinding and polishing, at the same time, brown fused alumina can be used to sandblasting derusting cleaning artifacts and refractory material.

$Brown Alumina For Refractory Castable$

Q: What materials is silicious thermal insulation board made of?: Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.

Q: Which manufacturers have the best fire-proof materials with light weight?: Tinajin SPstar Insulation Material Co.,Ltd. is Chinese agent of German Berkson which is engaged in the application of field of high temperature and thermal insulation for many years and has accumulated experience of application of WDS nanometer scale micropore thermal insulation matrial in a variety of industries. Welcome domestic customers and experts in all industries to contact us and cooperate to promote this new energy-saving insulation materials. Make due contributions for China's energy-saving and sustainable development and low carbon emissions project!

Q: Can anyone tell me the requirements of the refractory masonry?？: Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.

Q: What are the standards of refractory concrete ?: It can be divided into: 1. Ordinary refractory concrete Aggregates used include high alumina, clay, silica, basic materials (magnesite, chromite, dolomite, etc.) or special materials (carbon, silicon carbide, zircon, etc.). It can also use several combination of refractory material. 1. Thermal insulated refractory concrete It is mainly formulated with refractory light aggregates. The light aggregate used can be expanded perlite, vermiculite, ceramsite, porous chamotte, alumina hollow ball, etc. It can also be a combination of several refractory light aggregates or combination of the refractory aggregates. The aggluetination material used in refractory concrete can be high alumina cement, phosphate binders, water glass binder and clay, etc.

Q: What are the refractory materials above 1000℃: It is a piece of cake to meet your requirement, anyway you can try unshaped castables like corundum and other refractory materials used in steelmaking which are above 1500℃ basically .

Q: Which brand of AAA refractory is good?: The most famous is fire dragon. The Morgan and Lu Yang are all very good at making common thermal insulation material. The price is not very expensive, and the quality is comparatively good. The refractories are capable of good thermal shock resistance ability and chemical errosion resistance ability It is a non-metal material with a low heat conductivity coefficient and expansion coefficient. It requires high temperature in nature. The production base of silicious thermal insulation board is difficult to transport raw material. The silicious thermal insulation board is a high temperature thermal insulation material with the raw material of non-porous refractory?aggregate and porous refractory?aggregate, organic fiber and inorganic fiber.

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: I wanna ask what are the acidic refractories?: You can look at these: (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. I hope it is useful!

Q: which is better as household fireproof material ?: If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.
