Abstract

The invention discloses a production method of multifunctional plum-blossom-shaped lightweight through-hole ceramsite containing bauxite. The technical scheme of the production method is characterized in that the multifunctional plum-blossom-shaped lightweight through-hole ceramsite containing the bauxite is prepared from ingredients through stirring, extruding granulation, drying, roasting, heat preservation, sieving and sealed packaging; the ingredients contain the bauxite, high-viscosity attapulgite clay, zeolite, activated clay waste residues, activated alumina, nano-zinc oxide, light magnesium oxide, light calcium carbonate, hollow microspheres, expanded perlite, expanded vermiculite and lauryl sodium sulfate, and the produced multifunctional plum-blossom-shaped lightweight through-hole ceramsite containing the bauxite has the characteristics of being good in adsorptive property, large in effective specific surface area, high in porosity, low in stacking density and high in lightweight strength and integrating micropores and macropores and is suitable for various greening projects such as water purification and filtration, soil remediation, landscaping, roof greening, desertification control and the like; the production method of the multifunctional plum-blossom-shaped lightweight through-hole ceramsite containing the bauxite is suitable for producing the multifunctional bauxite-containing lightweight through-hole ceramsite with different shapes such as a plum-blossom shape, a cylindrical shape, a spheroidal shape and the like.

Description

technical field [0001] The invention relates to ceramsite, in particular to a production method of multifunctional quincunx-shaped bauxite lightweight through-hole ceramsite. Background technique [0002] In the water purification and filtration process, a large amount of ceramsite filter material is required. The traditionally used ceramsite filter material is made of raw materials such as clay, clay and fly ash, which are granulated and sintered at high temperature. When cultivating or planting various seedlings, flowers and vegetables, fly ash ceramsite, clay ceramsite, shale ceramsite and flower ceramsite are often used as soilless cultivation substrates. [0003] Fly ash ceramsite, clay ceramsite and shale ceramsite are artificial lightweight aggregates, which use high-quality clay, shale or fly ash as the main raw materials, are roasted at high temperature in a rotary kiln, and are extruded. It has a honeycomb structure, so it has the characteristics of light weight, ...
