Factors affecting film faced plywood production
Glue
The quality of glue is one of the key factors affecting the quality of film faced plywood. If the unqualified glue is used when making the plate, the viscosity of the plate will be reduced, resulting in the opening of the formwork. Unqualified glue will make the cost of the product reduced and the quality of the product impossible to guarantee.
Core board
Plywood is mainly made by combining the wood materials. The quality of plywood is determined to the quality of raw materials. High quality plywood products must use high quality raw materials. If moisture excessive raw materials are used, moisture will make the glue unworkable. So the plywood will be tackless and peeling phenomenon. High-quality wood should be used as raw material, and proper treatment and drying can make plywood last longer.
Pressure
Film faced plywood is formed by pressing criss-cross thin plates under extreme temperatures and pressure. Although the quality of glue and the amount of glue used can affect the quality of the product, the pressure of the high-pressure machine is also a significant factor that cannot be ignored. It is usually the case that Film faced plywood is tightly bonded layer by layer. The combination needs at least 250 MPa of pressure. Merchants who aren't honest will lower the pressure to make the film faced plywood thicker and use fewer raw materials. However, this will reduce the quality of the product, as it is very easy to crack and cause problems with quality.
Moisture
Generally, the moisture content of wooden building forms is between 8-10% because the environment is usually around 8%. Any production process that speeds up the production cycle and reduces the drying time of the core board reduces the quality of the formwork. Make sure the humidity is not too high or too low. In order to save materials and increase the effect, the production should be strictly in accordance with the production cycle, and the necessary quality inspection should be carried out.
Production technology
The plywood production process involves slicing, gluing, billeting, drying, hot pressing, and log cutting, all of which require delicate operations. If the manufacturing process is flawed, it can lead to quality issues such as erroneous dimensions and unequal thicknesses of the plywood.
Production equipment
The equipment used to produce plywood will also affect the quality of the material. If the equipment used to make plywood isn't precise enough or is old, it could cause problems like plywood with different sizes and thicknesses. The use of fine production equipment can effectively improve the quality of products.
