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

Embodiment 1

[0044] (1) Stir and mix magnesium chloride, magnesium oxide, plant straw powder or sawdust, slag, adhesive, water, and glass fibers as reinforcing ribs, and inject them into the light wall panel mold; and arrange them as reinforcing ribs Glass fiber strips, shaped after vibration.

[0045] (2) Then use microwave heating to heat up the material in the mold to 45°C, crystallize as a whole, and the heating time is 10 minutes;

[0046] (3) Then place it in hot air for crystallization reaction, the crystallization reaction temperature is 60°C, and the time is 7 minutes;

[0047] (4) Before the material in the mold is cured, the surface is modified to keep it at a predetermined thickness and embossed;

[0048] (5) The corrected material is crystallized and solidified in hot air to complete the crystallization and solidification; the crystallization solidification temperature is 75°C, and the time is 12 minutes;

[0049] (6) Demoulding, taking out the cured material, and then curin...

Embodiment 2

[0052] Adopt the same method of embodiment 1, wherein adopt magnesite cement 30%, magnesium oxide 22%, fly ash 17%, sawdust 33%, gypsum 1.2%, oxalic acid 0.026%, iron trichloride 0.026%, triethanolamine 0.03 % and the balance of water to prepare a paste. All the above are percentages by weight.

[0053] Microwave heating temperature to 35 ℃, heating time is 5 minutes;

[0054] The hot air crystallization reaction temperature is 90°C, and the time is 10 minutes;

[0055] The crystallization solidification temperature is 30°C, and the time is 15 minutes;

[0056] (6) Demoulding, taking out the cured material, and then curing the cured material to obtain a finished product.

[0057] (7) Curing means that the products after demoulding from the assembly line are placed in a ventilated yard for 5 days. During this period, heavy pressure, rain, water immersion, and single-point stress are not allowed. They can be stacked so that the mixture in the finished product The whole materia...

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 ...
