Building ceramsite
Building clay can be used for concrete
Ceramic concrete has been widely used in various types of prestructural components of industrial and civil buildings and porous brick ceramic produced by cast-in-place concrete as aggregate, and can also be used in pipe insulation, furnace insulation, cold insulation and sound insulation, sound absorption and other building materials. It can also be used as soilless bed material and water filter material in agriculture and garden. What is common in our life is the use of bathroom refill at home. Due to its characteristics of light weight, high strength, good thermal performance, low water absorption rate and small shrinkage value, it is especially suitable for the pumping of light and coarse aggregate concrete for high-rise shear wall building. According to hubei yichang binjiang international top huacheng commerce-residence building, ceramsite concrete has been successfully implemented pumpcrete FCF to 101 m elevation, due to the dry density of lightweight aggregate concrete LC30 small, thermal resistance of concrete is bigger, can save a lot of for high-rise building steel, cement, such as with other energy saving measures, can form the hot summer and cold winter and hot summer and warm winter area of reinforced concrete shear wall high-rise building ceramsite since heat preservation system.
Architectural pottery grains can be used for greening materials
Due to the special structure of porous, light and high surface strength, ceramic grains are used in landscaping and indoor greening to meet the need of water-containing plants and also meet the requirements of air permeability. Especially, their characteristics of no dust and light make them very common in office green plants. In the dry state, there is no dust pollution, bubble water does not disintegrate, does not produce mud water. If you have used peat soil and perlite, you will remember that it is a very laborious process to mix and stir them, because there will be dust, which will not only make the plant leaves dirty, but also will cause discomfort by inhaling the dust. The small holes of pottery grains with magical tools are good stewards of plants for water absorption and ventilation. In terms of horticulture and cultivation, there are many small holes in the pottery grains from the surface to the inside. These holes will try to absorb water when watering, and the porous pores will be fully ventilated, so that the plants will not have the feeling of being immersed in water.
Architectural pottery grains can be used as dietary hygiene materials
Porous ceramsite besides having higher physical performance, weight, surface strength, in the process of production also has the certain active substances, and already used in daily life related aspects such as drinking water, wash bath to, such as in the water dispensers for filtering water, add water in the shower shower handle activity, etc. So clay tablets are also common in waterworks and sewage treatment plants. Ceramic filter material has been widely used because of its high specific surface area, good chemical and thermal stability and low price. Building ceramsite in applications is undoubtedly good products by building businesses and consumers certainly, highlight the characteristics of the product, as a new type of material, because of its light weight, high strength, small coefficient of thermal conductivity, bibulous rate is small, high temperature resistant, anti-aging, acid and alkali resistance, no radiation, environmental protection and energy saving features and widely used in the construction field. At the same time, pottery grains have been used in all aspects of society.
Architectural pottery granules can be used for industrial filtration materials
The active substance of pottery grains is also used in many industries. The biological ceramic filter can be used as the biological film carrier of the high load biological filter tank for industrial waste water, the water source of micro-pollution and the pretreated biological filter tank. The crude granular material containing oil wastewater, the resin cushion of the air blast biological filter of ion exchange ceramic, and the microbial dry storage; It is suitable for the deep treatment of drinking water. It has adsorption of harmful elements in water body, bacteria and mineral water, and it is a filter material with good effect of active biodegradation of harmful substances and a good biofilm carrier in biological filter tank. There are many reports on the treatment of zinc-containing wastewater at home and abroad, mainly focusing on the study of zinc-containing membrane technology using emulsion liquid membrane. Activated carbon is usually used as adsorbent in the treatment of heavy metal ionic wastewater by adsorption method. Due to the high price of activated carbon, its application is limited to a certain extent. Treatment of zinc-containing wastewater with ceramic particles as adsorbent has not been reported. As a kind of artificial lightweight aggregate, ceramic particles are mainly used for preparation of lightweight aggregate concrete, lightweight sand slurry and acid-resistant and heat-resistant concrete aggregate. It is made of clay material such as shale, first broken to a certain size, or use a orbed, such as clay, fly ash mixed clay again at high temperature (1050 ℃ ~ 1350 ℃) burning swelling or sintering, due to its internal porous, larger specific surface area, good chemical and thermal stability, has good adsorption performance, easy to regenerate, to facilitate reuse, is a kind of cheap adsorbent, it was found that haydite on zinc has strong adsorption ability, in wastewater pH4-10, the concentration of 0 mg/L ~ 200 mg / 1 range, according to the quality of zinc and ceramsite 1: At the proportion of 80, the removal rate of zinc contained waste water is more than 99%, and the treated waste water containing zinc can meet the discharge standard.
At
present, this kind of filtration method has been more and more applied in water treatment plants, and the application of pottery granule in water treatment is far more than that, and it is more widely used in biological filter materials.
