preparation example Construction

[0012] The preparation method of the mineral material powder derived from urban waste is: crushing and sorting the urban waste once, sorting out the mineral materials (materials composed of various inorganic salts and inorganic metal oxides), and separating the mineral materials The material is crushed into fine particles for the second time to form the above-mentioned mineral material powder derived from municipal waste.

[0013] The primary crushing can use a jaw crusher, which has a large crushing ratio, simple structure, uniform particle size of the crushed material, and the equipment itself has a simple structure, relatively high operating costs and maintenance costs, and is suitable for municipal waste processing. Crushing of materials with complex composition and properties.

[0014] If necessary, the primary crushing can be divided into two steps. The first step is to use the above-mentioned jaw crusher to crush large pieces into small pieces, and the second step is to...

Abstract

The present invention relates to an environment-protecting heat preserving board and the preparing method thereof, the heat preserving board is formed by mixing the foam slurry and the slurry and then pouring in the mold, the principal raw material of the slurry comprises the following components: light-burned magnesium dust, magnesium chloride, oxalic acid, mineral material powder from the urban garbage, shale and glass fiber, the method for preparing the mineral material powder from the urban garbage is executing a primary crushing and sorting to the urban building material, sorting the mineral material wherein, secondary crushing the mineral material to fine particles, and forming the mineral material powder from the urban garbage. The present invention provides an excellent cyclic utilization approach to the mineral material in the urban garbage, realizes that the waste is turned into treasure, is propitious to protect resource and environment, the compression strength of the manufactured heat preserving board is high and the heat preserving capability is well, and can be used as the heat preserving overlay board, partition plate and roof plate and the like of the wall.

Description

technical field [0001] The invention relates to an environment-friendly thermal insulation board, and also relates to a manufacturing method of the thermal insulation board, which belongs to the technical field of environmental protection. Background technique [0002] Existing thermal insulation boards are mostly formed by pouring foamed concrete into a mold to solidify. The concrete slurry is made of cement as the main raw material, and the foaming agent is used to make foam slurry through a foaming machine. The concrete slurry and foam slurry are mixed and poured on In the mold, the plate is formed after natural curing and solidification, and the purpose of heat preservation is realized through the foam heat insulation effect in the plate. The disadvantage of this kind of board is that the raw materials are mainly derived from newly mined minerals, which consumes a lot of resources and is not conducive to environmental protection. [0003] On the other hand, urban waste ...
