Production method of multifunctional quincunx red mud light through-hole ceramsite

Abstract

The invention discloses a production method of multifunctional quincunx red mud light through-hole ceramsite. The key point of the technical scheme is that the ingredients are subjected to stirring, extrusion granulation, drying, roasting, heat preservation, screening and sealing and packaging to obtain the multifunctional quincunx red mud light through-hole ceramsite; and the ingredients include red mud, high-viscosity attapulgite clay, zeolite, activated clay waste residue, activated aluminum oxide, nano zinc oxide, light magnesium oxide, light calcium carbonate, hollow microspheres, expanded perlite, expanded vermiculite and sodium dodecyl sulfate. The multifunctional quincunx red mud light through-hole ceramsite has the characteristics of good adsorption property, large effective specific surface area, high porosity, low bulk density, light weight and high strength and integration of micropores and macropores and is suitable for multiple landscape engineering such as water purification and filtration, soil remediation, landscaping, roof greening and desert control; and the production method of multifunctional quincunx red mud light through-hole ceramsite is suitable for producing multifunctional red mud light through-hole ceramsite of different shapes such as quincunx, cylindrical shape and spherical shape.

Description

technical field [0001] The invention relates to ceramsite, in particular to a production method of multifunctional plum-shaped red mud 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, high...
