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.
Chrome corundum brick refers to corundum refractory products containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chromium corundum products is better than that of pure corundum products. Chromium corundum products are widely used, and the content of Cr2O3 is mostly in the range of 9% to 15%.
low porosity clay bricks are mainly used in the regenerators of glass kilns. They can also be used in blast furnaces and hot blast furnaces in the steel industry; cement kilns in the building materials industry; chemical kilns in the chemical industry as kiln linings
Calcined alumina is a product obtained by calcining aluminum hydroxide at high temperature to partially or almost completely convert it into aAl2O2.
The high-alumina refractory bricks sold by Yuying refractory manufacturers are commonly used refractory bricks with high thermal stability and refractoriness above 1770°C. It has good slag resistance and is used for the lining of steelmaking electric furnaces, glass melting furnaces, cement rotary furnaces, etc.
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.
Ceramic wear resistant castable is a special material and is a new type of material developed recently. It not only meets the needs of national defense cutting-edge products and high-tech development, but also meets the requirements of the rapid development of the national economy. Therefore, it is easier for users to accept than other materials, so it develops rapidly.
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.
