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

Abstract

The invention discloses a production method of multifunctional plum-blossom-shaped lightweight through-hole ceramsite containing vermiculite. The technical scheme of the production method is characterized in that the multifunctional plum-blossom-shaped lightweight through-hole ceramsite containing the vermiculite is prepared from ingredients through stirring, extruding granulation, drying, roasting, heat preservation, sieving and sealed packaging; the ingredients contain expanded vermiculite, high-viscosity attapulgite clay, zeolite, activated clay waste residues, activated alumina, nano-zinc oxide, light magnesium oxide, light calcium carbonate, hollow microspheres, expanded perlite and lauryl sodium sulfate, and the produced multifunctional plum-blossom-shaped lightweight through-hole ceramsite containing the vermiculite 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 vermiculite is suitable for producing the multifunctional vermiculite-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 plum-shaped vermiculite 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, perlite ceramsite and flower ceramsite are often used as soilless cultivation substrates. [0003] Fly ash ceramsite, clay ceramsite and perlite ceramsite is a kind of artificial light aggregate, which uses high-quality clay, perlite or fly ash as the main raw material, and is roasted at high temperature in a rotary kiln and expanded. It has a honeycomb structure, so it has the characteristics of light we...

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
