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.
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%.
The heavy part of the raw materials for the chrome zirconium corundum composite brick is sintered tabular corundum, high-purity chromium oxide, high-purity zircon, and Guangxi white cement.As the main raw material, the light part of the raw material is made of 47 mullite, kyanite, floating beads and coke gemstones as the main raw materials. During molding, a separator is set in the middle of the mold, and heavy materials and light materials are added at both ends. After high pressure molding , finished products made of high temperature sintering.
Silica bricks for coke ovens are siliceous refractory products used for building coke ovens with tridymite as the main crystal phase. Coke oven silica bricks are used to build regenerator walls, ramps, combustion chambers, carbonization chambers and furnace roofs of coke ovens. Silica brick is an acid refractory material with good resistance to acid slag erosion. The softening temperature under load is as high as 1640-1670 °C, and the volume is relatively stable in long-term use at high temperature.
high alumina refractory bricks is mainly used around the furnace cover, electrode holes and exhaust holes of electric furnaces, and its service life is 1 to 2 times longer than that of silica bricks.
Silica brick is an acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phases
The refractory ramming material is prepared from a high proportion of granular and powdery materials and a very low proportion of binders and other components, even all of which are composed of granules and powders, and are subject to strong ramming. Bulk materials for construction.
Refractory ramming mass (refractory taphole mass) is a kind of Refractory used for lining of blast furnace tapping groove. It is mainly used to protect the blast furnace out of the ditch from high-temperature hot metal and slag erosion and erosion, and has excellent high-temperature resistance and wear resistance. The ramming material for the iron discharge ditch is usually composed of corundum, silicon carbide and carbonaceous material, which has the ability of resisting hot metal and molten slag erosion and scouring, reburning line change small, strong resistance to a variety of oxidation characteristics. The construction of the ramming material for the iron ditch is convenient, easy to dismantle and repair, does not produce harmful gas, and is beneficial to environmental protection.
