Problems solved by technology

[0002] Most of the exterior walls and partition walls of existing domestic high-rise buildings are hand-built with red bricks, cement bricks, lighter foam bricks and other materials, and then leveled after several times of plastering, which is very laborious and expensive. High, long construction period, masonry unit volume weight, high cost of design building mechanics, large amount of steel, wet construction is not environmentally friendly, etc.

Abstract

The invention discloses a coal cinder sandwich wallboard production method. The coal cinder sandwich wallboard production method comprises the following materials: coal cinder ash, iron ore slag, powder rock sand, perlite particles and cement form dry mixtures; polystyrene granules, water and multiple additives are added in the dry mixtures; the multiple additives comprise methylcellulose, emulsion powder, early strength agents, water reducing agents and air entraining agents; and a production system comprises a coal cinder ash bucket, an iron furnace slag bucket, a powder rock sand bucket, aperlite particle bucket, a cement bin, a polystyrene granule bin, a raw material bin, a puffing bin, a stirrer, a mold, an expanding unit, a mold car, a belt machine, an electronic scale, a skip, an additive library and a water pump. The coal cinder sandwich wallboard production method is characterized in that the materials in each bucket needed by formulas of 30 boards are unloaded to the belt machined and loaded to the lifting skip to send to the stirrer through control of the electronic scale by a computer; the polystyrene granules are charged in the stirrer; the water and the additives areadded for full stirring; and water mixtures are filled in a prepared combination mold for molding. The coal cinder sandwich wallboard production method can change wastes into valuable things, and canprepare pure natural, green, ecological and environment-friendly wall materials.

Description

technical field [0001] The invention relates to a method for producing a cinder sandwich wallboard, which belongs to the technical field of building materials. Background technique [0002] Most of the exterior walls and partition walls of existing domestic high-rise buildings are hand-built with red bricks, cement bricks, lighter foam bricks and other materials, and then leveled after several times of plastering, which is very laborious and expensive. High, long construction period, unit volume weight of masonry, high cost of design building mechanics, large amount of steel, wet construction is not environmentally friendly, etc. Contents of the invention [0003] In order to overcome the defects of old-fashioned brick partition walls, the first problem to be solved by the present invention is to provide a cinder sandwich wallboard production method that shortens the construction period, reduces labor and equipment investment, and is environmentally friendly. [0004] The...
