Introduction to the production process of building template

building templates in the project construction to the project quality control has an important impact.The smoothness and flatness of the formwork surface will directly affect the flatness of the engineering concrete surface.Therefore, the template production should be controlled according to strict production process, and the production technology should be improved in the links of raw materials, glue coating, hot pressing and trimming, etc. The specific production process is as follows:

Cutting: 1. The raw materials are raw materials according to log layer cutting, and the logs according to certain thickness in horizontal plane cutting lathe cutting, according to the size of the template is proportional to the size before cutting the same wood floors, and clear the magazine on the surface of the wood floor, magazine late can affect the adhesive bonding fastness.

2. Drying, dry processing: after cutting and rotary cutting wood layer contains relatively large water, therefore, mass production, we are going to through the wood dryer drying process, after drying the wood floor is more brittle, therefore, to natural place 2-3 days, can guarantee the toughness of the wood floor.In a small number of cases, we can use sunlight for drying treatment.

3. Glue, alloy layer handles: a molding building templates, are adopted multi-storey wooden plank glue method is adopted to improve the bonding together, set up special rubber roll machine, the wooden plank by glue machine, plate will be evenly daub protectionlayer, middle of the front of the coated with rubber wood plank smooth placed on the surface of the template template, uniform of cladding layer 6-10 (as needed).

4. Hot forming treatment: the formwork layer is laid with glue and pressed flat through the hot pressing process.Traditional heating boiler water is adopted to heat for heating, modern equipment room used the electric heating, after pressing, can increase the compactness of building templates, forming rules, improve the quality of the use of templates.By preloading and then hot pressing process, the highest degree of reduce the chance of blank plate dislocation, again with reasonable pressure and temperature hot pressing, ensures that each Chinese building template has excellent bonding strength and hardness.

5. Paint, trim packaging processing: after hot pressing process of building the template, there will be a little inner wooden plank appear dislocation and the edge is not neat, kedao excess plate is adopted to improve the cutting, and spraying anti-corrosion paint, anti-corrosion paint is to guarantee the service life of the building template and storage time of the most important factors.The building template has the advantages of light weight, heavy weight, convenient bottling, smooth surface and anti-corrosion.
