Do you know about the production process of architectural aluminum formwork? In the production process, we must be very strict control, progress in the production of raw materials, coating, hot pressing and trimming process technology, construction of aluminum formwork in the construction of the project on the project Quality control has a significant impact. Lubrication and flatness on the surface of the formwork will directly affect the flatness of the concrete surface. The following Xiao Bian take everyone to specifically understand the production process.
In the first step, the raw material is cut: the raw materials are cut into layers according to the logs, and the logs are cut along the horizontal plane according to a certain thickness, and the wood layers are cut to the same proportion according to the standard size of the template. In addition, impurities on the surface of the wood layer are removed, and the impurities can affect the adhesive fastness of the glue in the later period.
The second step, drying, monotonous treatment: cutting and peeling of the wood layer behind contain relatively large amounts of moisture, therefore, large-scale production we must go through the wood dryer drying process, after drying the wood The layer is relatively brittle, therefore, to be placed naturally for 2-3 days, the patience of the wood layer can be guaranteed. In a few cases, we can use the sun for drying.
The third step, gluing, layering treatment: a formwork of aluminum template for construction, are selected to use a multi-layer wood plate adhesive method to bond together, set a special roll-gluer, the wood plate After the gluing machine, the front and back sides of the sheet will be uniformly altered and the wooden sheet coated with the adhesive layer will be placed on the surface of the stencil and evenly laid on the surface of the stencil with 6-10 layers (according to demand).
The fourth step, hot-press forming treatment: After the template layer laid by the glue, it is flattened by the hot-pressing process. In the traditional heating, the boiler water is used to transfer heat to heat, and the modern equipment room uses electric heating. After the flattening, the density of the aluminum template can be increased to form a comparative rule and the quality of the template can be improved. The pre-pressing and hot-pressing process is selected to minimize the probability of misalignment of the slab, and then a reasonable pressure and temperature hot press is applied to ensure that each aluminum template of our building has excellent bonding strength and hardness.
