Application:
In a certain operating and regeneration conditions,Active alumina ball desiccant has drying depth of up to -40 degrees below the dew point, is a trace of water depth of the desiccant efficient, single molecule adsorption layer of net heat, So very suitable for non-thermal regeneration device.
① Active alumina ball desiccant can be used as a defluorination agent of high fluoride drinking water (fluoride removal capacity), alkyl benzene production cycle of defluorination agent, transformer oil deacidification regeneration agent;
② Activated alumina ball desiccant can be used as oxygen desiccant for the oxygen industry, textile industry, automatic instrument, chemical fertilizer and petrochemical industry, and the dew point of PSA in the air separation industry can reach -55 degrees;
③ High-performance activated alumina ball in the unshaped refractory ingredients can bring the following benefits: to improve the density of the body, fluidity, strength, increase the amount of secondary mullite, reduce the water and porosity;
④ In addition as a desiccant, the active alumina ball can also be contaminated with oxygen, hydrogen, carbon dioxide, natural gas and other lubricants in the adsorption of steam;
⑤ Active alumina ball can be used as a catalyst, catalyst carrier, chromatography analysis of the carrier.
Packing
① Packing: 25kg / bag (lined with plastic bags, the outer layer of plastic laminated bags). This product is non-toxic, to be waterproof, moisture-proof, non-oil and oil contact with steam.
② Transport: Do not drag with iron hook, prevent to be mixed with hard materials, not strong vibration, friction, step on, smashing, throwing is prohibited, should be light loading and unloading to reduce the packaging broken.
③ Storage: Store in a cool and dry place, to prevent the rupture of inner and outer bags, to prevent moisture and other substances affect the use of results, storage away from sources of pollution; Do not open the package before use, so as not to absorb moisture and affect the use of results.
④ Applicable conditions: activated alumina ball desiccant is for deep drying, pressure> 5kg/cm2 is appropriate.
⑤ Regeneration: activated alumina ball on gas, water vapor and some liquid moisture has selective adsorption capacity. Adsorption saturation can be heated at about 175-315°C to remove water and resurrection, adsorption and resurrection can be carried out several times.
White corundum is made from industrial alumina powder, which is smelted in an arc at a high temperature above 2000 ℃ and then cooled. After crushing and shaping, magnetic separation to remove iron, it is divided into various particle sizes.
Corundum bricks are mainly used in iron-making blast furnaces and blast furnace hot blast furnaces, refining furnaces outside steel-making furnaces, sliding water heaters, glass melting furnaces and petrochemical industrial furnaces, etc.
The refractory pre -production is the category of irregular refractory materials, also known as the prefabricated block of the pouring materials, and the irregular refractory prefabricated block.
Fireclay bricksis suitable for supporting hot blast stoves of large, medium and small blast furnaces
Yuying Refractory produces a complete set of refractories for electrolyzers, and the new impermeable bricks are used in conjunction with impermeable castables
Brown Fused Alumia powders are fused wIth premium raw materials and 3500 KVA furnace. It is perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, polishing and sandblasting grit. It has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials. It is also be used as high-class refractory materials. Brown Fused Alumia is offered in macro and micro powder form, in both F and P grades.
silicon mullite brick is a kind of refractory brick product made of super high alumina bauxite and silicon carbide as raw materials through a special sintering process. It has the characteristics of continuously forming a protective layer and reducing ring formation, and its heat resistance is also very good. The softening temperature under load can reach 1600 ℃, and the service life is long. Mainly used in the transition zone, decomposition zone and cooler of small and medium-sized cement kilns.
Silicon carbide used in industry is a synthetic material, commonly known as emery. Silicon carbide is one of the most commonly used non-oxide refractory raw materials in the field of refractories.
