Description

Method for manufacturing carbonized cement

The present invention relates to a method of manufacture, and more particularly to a method of making a carbonized cement.

Glued materials are formed by bonding layers of wood through layers. For example, in the case of angle materials in glue materials, angle materials are the basic building materials for decoration, whether it is ceiling, compartment, false wall, TV wall shape, floor, etc. After the horning material is grounded and typed, the surface material is nailed to the horn, so the stability and durability of the horn are very important.

Generally, the angle materials are made of wood, and the effect of the solid wood corners is usually the best, but the growth of a solid wood is not easy, and the structure of the wood contains cellulose (polysaccharide). Moreover, there are some pests and microorganisms (such as molds) inside and outside, so it is vulnerable to the invasion of pests and microorganisms, causing damage to the structure of the angled material and the fragile support, and the solid wood cutting surface is difficult to arrange due to the wood grain. Control, usually produces a lot of burrs, and must pass through a running-in part to make the surface of the angle flat, which causes inconvenience in construction; in addition, the wood itself has the characteristics of water absorption, and if it is made of wood of inferior quality, it is also corrupted. And the problem of poor durability arises.

Therefore, usually the angle material is used to achieve the anti-corrosion effect, and usually the anti-corrosion syrup is invaded, and the anti-corrosion syrup usually evaporates to generate toxic gas (such as formaldehyde). If it is in a poorly ventilated environment, it usually causes a certain harm to human health. The need to improve the outside; plus the water content of the wood itself, usually has a certain weight, will also increase the overall weight of the decoration, therefore, how to create a lightweight, anti-corrosion, anti-mite angle for use For the purpose of the public.

Accordingly, it is an object of the present invention to provide a method for producing a carbonized cement which can produce a cementitious material which is light in weight, strong in strength, and which is excellent in corrosion resistance, moisture resistance and durability.

Thus, the method for producing a carbonized cement of the present invention comprises a preparation step, a preliminary bonding step, a carbonization step and a ply gluing step; wherein the preparation step is provided with a plurality of wood veneers, and each of the woods The thickness of the veneer is between 0.6mm and 3.1mm, and an adhesive is applied between any two wood veneers to respectively press the composite ply, and the thickness of each ply is less than 14mm (ie, the preliminary gluing step). Then, the plywood is clamped to the plywood through a hot press of a hot press, and the temperature is controlled between 180 and 205 degrees to carbonize the ply (ie, the carbonization step), and then the carbonized After the plurality of plywoods are pressed together, and then any of the plywood plates are pressed together by an adhesive, the manufacture of the gluing material can be completed (ie, the plywood gluing step); therefore, by the above method, a light weight and strength can be produced.

Further, in this embodiment, each of the wood veneers The wood grain and the wood grain of another wood veneer need to be stacked in the same arrangement direction, so that the adhesive glue can be dispersed in the direction of the wood grain during the pressing process, and each wood veneer can be made closer to the denseness during the pressing process. In addition, it contributes to the strength improvement, and the thermal conductivity between each wood veneer and another wood veneer in the subsequent carbonization step 33 is improved, and the temperature and time required for the carbonization process can be reduced, and the subsequent carbonization step can be reduced. 33 In addition to the cost, the subsequent wood grain direction can be cut even more smoothly.

Continuing the foregoing, the carbonization step 33 is provided with a hot press having two heat conducting plates, and the temperature of the heat conducting plate is controlled between 180 and 205 degrees to clamp the plate to the two heat conducting materials.
