Abstract

The invention discloses a production method of multifunctional quincuncial gypsum tailings lightweight through-hole ceramsite. A technical scheme of the method is characterized in that burden is subjected to stirring, extrusion granulating, drying, calcining, heat insulation, screening and hermetic packaging to obtain multifunctional quincuncial gypsum tailings lightweight through-hole ceramsite; the burden is prepared from gypsum tailings, high-viscosity attapulgite clay, zeolite, activated white clay waste, activated alumina, nano zinc oxide, lightweight magnesium oxide, lightweight calcium carbonate, hollow microspheres, expanded perlite, expanded vermiculite and sodium dodecyl sulfate; the ceramsite features good adsorbing performance, large effective specific surface area, high porosity, small bulk density, light weight but high strength, and integration of micropores and macropores, and is suitable for various greening projects, such as water purification and filtering, soil restoration, landscaping, roof greening, and desert control; the production method of the multifunctional quincuncial gypsum tailings lightweight through-hole ceramsite is suitable for the production of multifunctional gypsum tailings lightweight through-hole ceramsite in different shapes, such as quincuncial shape, cylindrical shape and spherical shape.

Description

technical field [0001] The invention relates to ceramsite, in particular to a production method of multifunctional plum-shaped gypsum tailings 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 weig...
