Building formwork plywood is an important process of construction, which should comply with safety, economy, and practicability.
These three aspects are related to the cost performance of the product. The quality and cost of wood formwork are determined by the reasonable and perfect production process, which is why we should understand the production process of wood formwork.
The main raw materials of the plywood are poplar birch eucalyptus and pine, which are produced through 13 production processes through the introduction of international advanced glue-making technology. Part of the board plays a supplementary role, such as the fifth and sixth processes below followed by manual glue repair, which are summarized in 9 processes:
1. Log saw cut rotary cutting
We choose high quality pine/eucalyptus/birch/poplar logs, according to the length of the veneer required for production budget sawing, and then through the precision rotary cutting machine for rotary cutting, reasonable use of resources and improve the quality of formwork plywood;
2. Veneer drying and finishing
The use of natural sunlight in large yards, natural drying, then packaging, to ensure that the production process requirements. To manufacture high quality formwokr plywood;
3. Wood chip pressing and cleaning
The machine presses and cleans the surface of the sun-dried wood chips to provide conditions for the next step of gluing;
4. Veneer coating group blank
Precision high quality four roller coating machine, to ensure that each veneer coated evenly to achieve high bonding strength. Horizontal and vertical interleaved billet mode, so that each zgreat plywood is up to the national standard;
5. Waterproof paint
In order to improve the waterproof and anti-corrosion performance of the template, the plywood is rolled again by the equipment, and the product is much stronger.
6. Hot pressing of blank plate
The process of pressing and then hot pressing is adopted to reduce the probability of dislocation of the blank plate to a higher degree, and then apply reasonable pressure and temperature hot pressing, to ensure that each piece of ZGREAT formwork plywood has excellent bonding strength and hardness, transfer the next process, and further supplement the place where the machine can not paint;
7. Cut the edge
Precision edge cutting machine will hot press forming blank plate after cutting the required size, and quality control classification;
8. Upper edge paint
Artificial paint around the plywood, improve the waterproof performance of the plywood in all aspects;
9. Pack and store
According to the customer or company’s requirements, according to the specified height and quantity of packing into the warehouse to be shipped
