1, Pay attention to the quality of raw materials:
High-quality plywood more whole board whole core, uniform texture, no obvious knots and scars, high-quality wood made of plywood is more durable, able to withstand the side pressure of the concrete pouring, to prevent deformation of the template, the service life will be longer.
2, Pay attention to the production process:
Advanced production technology can ensure that the size of plywood is accurate, tight splicing. In the production process, hot pressing, gluing and other processes properly handled, can enhance the overall strength and stability of plywood. For example, plywood edge sealing treatment, can prevent moisture penetration, extend the service life of the template.
3, Do a good job of appearance check:
Observe the plywood surface is flat and smooth, there is no obvious deformation, cracks, breakage and other defects. Quality plywood surface should be free of bubbles, scratches, uniform color. Also check the plywood surface for unevenness, knots and other defects. If the surface of plywood is rough or defective, the concrete will also show corresponding marks on the surface after solidification, which is not favorable for the subsequent decoration works. Obvious unevenness or defects on the surface of the slab may affect the effect of concrete pouring.
4, Performance test:
Through the actual test, to understand the plywood bearing capacity, deformation. Such as static load test to detect the degree of deformation of plywood when bearing a certain weight. At the same time, test plywood's waterproof, fireproof performance, etc., to ensure its normal use in a variety of engineering environments.
5, Focus on brand and reputation:
Choose strength brand, plywood quality is usually more guaranteed. Check the brand's market reputation, product qualification, user evaluation and other sex. Some companies that have been engaged in the production of plywood for a long time have accumulated a good reputation in the industry.
When purchasing plywood, the above factors should be considered comprehensively. Through careful inspection and testing, choose plywood with reliable quality to provide guarantee for the smooth progress of the construction project.
