Method for preparing exterior wall decorating plate from combustible refuse

Abstract

The invention discloses a method for preparing an exterior wall decorating plate from combustible refuse. The method for preparing the exterior wall decorating plate comprises steps as follows: (1), refuse is screened, and combustible refuse is selected; (2), the selected combustible refuse is rubbed to form strips, and the strips are required to be larger than 1 cm; (3), the rubbed combustible refuse strips are uniformly mixed with cement slurry, the mixture is uniformly spread on a conveying belt, a cement throwing jet is arranged above the conveying belt and sprays cement slurry from top to bottom to fill gaps of the mixture, then two rollers rotating oppositely of a belt conveyor roll the mixture, plates with a designated thickness are formed, and finished products are obtained after drying. The exterior wall decorating plate is prepared from the combustible refuse and the cement, a large amount of combustible refuse can be consumed, and the manufacturing cost is low. The anti-bending strength and the anti-cracking performance of the exterior wall decorating plate are good. Trouble caused by mounting and dismounting of a mold is omitted, the production efficiency is high, the production cost is low, the exterior wall decorating plate does not need to be painted or additionally decorated during use, time and labor are saved during building, and the cost is low.

Description

technical field [0001] The invention relates to a method for preparing an exterior wall decorative board from combustible garbage. Background technique [0002] Entering the 21st century, green and environmental protection have become the theme of the world. With the rapid development of my country's national economic construction, energy conservation, emission reduction, low-carbon and circular economy have become my country's major policies. The building materials industry is the industry that eats the largest amount of slag and garbage, and shoulders the heavy burden of circular economy. [0003] In order to reduce construction costs and improve construction efficiency, the walls of buildings are all cast-in-place walls. That is to build the wall mold (also called plywood) first, then pour concrete into the mold to form the wall, then disassemble the mold to get the wall, and then paste the exterior wall board or paint the exterior wall on the wall, which is completed T...

AI Technical Summary

Problems solved by technology

[0004] Traditional construction molds are cumbersome to install and disassemble, labor-intensive and time-consuming, and the manufacturing cost is high

Moreover, after the concrete wall is formed, it is necessary to paint the exterior wall or paste the exterior wall panels, which is a complicated manufacturing process.
