Light wall board producing process and apparatus

Abstract

The present invention discloses light wall board producing process and apparatus. The production process includes the following steps: mixing magnesium chloride, magnesium oxide, plant stalk powder or saw dust, mineral slag, adhesive, water and reinforcing glass fiber and forming inside mold; microwave heating, trimming, crystallizing in hot blast, demolding, and curing to obtain product. The present invention has short production period, high production speed, high product quality, low power consumption and other advantages.

Description

technical field [0001] The present invention relates to a method and device for preparing wall panels, in particular to a continuous production method for lightweight wall panels made of composite materials such as magnesium chloride, lightly burned powder, plant straw, wood chips, slag, and glass fibers and device. Background technique [0002] Lightweight wall panel is a kind of building material composed of magnesium chloride, lightly burned powder, plant straw, wood chips, slag and glass fiber, etc. It has a very wide range of applications in the construction field. [0003] At present, most of the light wall production is manual operation. On the cement or other structural platforms, the light wall panel is equipped with a mold, and the mixed materials of the light wall are synthesized in the mold. The light wall The mixed material naturally absorbs heat, reacts, crystallizes, and solidifies. Each person produces and processes several sets per day. When the production ...

Problems solved by technology

Obviously, the demoulding time of the device is greatly affected by the temperature of the production environment, water vapor saturation, etc., generally as long as ten hours or even more; the product quality is unstable due to human factors and climate changes, and cannot be completed on time Continuous production and processing cannot meet the needs of the development of the construction field;

[0004] In order to overcome the above-mentioned defects, the Chinese patent ZL00222065.2 designed a small molding machine, which can realize small-scale production and processing of single or several pieces of special-shaped and relief. Due to the small single-piece / several-piece mold molding production, it still cannot form Large batches of continuous operation; and the characteristics of the application in this processing are heat conduction heating methods such as vacuum and pressure difference, electric heating and steam heating, resulting in large heat energy loss, slow processing speed, and unstable product quality.

[0005] Both of the above two methods and devices have a low degree of production mechanization. During the crystallization and solidification process of the lightweight wall panel mixture, the former naturally absorbs heat without equipment to provide heat energy, and the latter has no equipment to provide overall heating heat energy. In this case, the produced Wall panels, whose products crystallize and solidify for a long time, and there are a lot of manual work at the same time, without complete continuous equipment configuration, production and processing in this way, product quality and output cannot be stable
