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.
Yuying Refractory produces a complete set of refractories for electrolyzers, and the new impermeable bricks are used in conjunction with impermeable castables
Refractory wet mud used to block the iron outlet can be divided into two categories: water cannon mud and waterless gun mud. On large and medium -sized blast furnaces on high top pressure and high degree of smelting.
Magnesia chrome bricks are refractory products with magnesia (MgO) and chromium trioxide (Cr2O3) as the main components, and periclase and spinel as the main mineral components. The main raw materials for the manufacture of magnesia-chrome bricks are sintered magnesia and chromite.
Anti stripping high alumina bricks are referred to as anti-stripping bricks or anti-stripping refractory bricks. Anti-stripping high-alumina bricks are widely used in my country's new dry process kiln, Libore kiln and wet process kiln, including kiln door cover, rising flue, cooling zone, decomposition zone, safety belt, transition zone, coolant rear Walls and side walls and beams with curved ceilings.
Common low-creep high-alumina bricks can be used in blast furnace hot blast stoves, as well as other industrial kilns, and can also be made into low-creep high-alumina bricks of different sizes according to specific construction requirements, such as lattice bricks, special-shaped bricks, anchor bricks, etc. , mainly used in industrial kilns in long-term high temperature environments
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.
Anchor bricks are anchor bricks for industrial kilns. The electric furnace roof is a furnace roof structure supported by metal hanging bricks and refractory bricks. Therefore, the leakage of reactive gas and hot gas in the furnace will damage the metal hanging parts, thereby causing furnace damage. roof collapse accident. Anchor bricks are also called hanging bricks and anchors.
The Al2O3 content of clay heat Clay insulating refractory bricks is generally more than 40%, and the Fe2O3 content is less than 2.0-2.5%. The clinker in the ingredients is 65-85%, and the combined clay is 35-15%. The crushed bonded clay and the finely ground clinker are mixed and milled, and then mixed with the granular clinker to make semi-dry mud, high pressure molding, and sintering at about 1400 ℃, with good performance.
