Production method of multifunctional plum-blossom-shaped gypsum lightweight through-hole ceramsite

Abstract

The invention discloses a production method of multifunctional plum-blossom-shaped gypsum lightweight through-hole ceramsite. The technical scheme is characterized in that the multifunctional plum-blossom-shaped gypsum lightweight through-hole ceramsite is prepared from ingredients by stirring, extruding and granulating, drying, roasting, standing at the constant temperature, sieving, and sealed packaging; the ingredients comprise gypsum, high-viscosity attapulgite clay, zeolite, activated clay waste residues, activated aluminum oxide, nano zinc oxide, lightweight magnesium oxide, lightweight calcium carbonate, hollow microspheres, expanded perlite, expanded vermiculite and lauryl sodium sulfate, and the multifunctional plum-blossom-shaped gypsum lightweight through-hole ceramsite has the characteristics that adsorption performance is good, the effective specific surface area is large, the porosity is high, the bulk density is low, the lightweight strength is high and micropores and macropores are integrated and is applicable to water purification and filtration, soil remediation, landscaping, roof greening, desertification control and other landscape engineering; the production method of the multifunctional plum-blossom-shaped gypsum lightweight through-hole ceramsite is applicable to production of multifunctional gypsum lightweight through-hole ceramsite in 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 plum-shaped gypsum 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 ...

Problems solved by technology

[0012] In contrast, the bulk density of these types of ceramsite is relatively large, resulting in relatively small effective specific surface area and low water absorption rate. Users hope to invent a kind of ceramsite with good adsorption effect, fast filtration speed, and bulk density ≤ 800kg / m³ And lightweight ceramsite with a water absorption rate of ≥65%, suitable for water purification and filtration, soil restoration and various greening projects
