Why the blockboard will not be qualified China's top ten environmental protection sheet Wan Zhoulin
The defective item of blockboard is impregnated and stripped.
There are four reasons for the failure:
One is to use urea formaldehyde or modified glue with low solid content;
Second, the moisture content of the core strip, the middle plate and the watch plate are not well controlled;
The third is hot pressing temperature and hot pressing pressure, and the time is not well controlled;
The fourth is the use of the core bark.
Â
The consequence is that the static bending strength and the immersion peeling performance of the wood-based panel products are unqualified, which may result in the bearing capacity of the product, the impact resistance is weakened, and the service life of the product is affected.
The surface of the impregnated paper laminated wood floor is not well-weared, which may result in a shortened service life of the floor during use.
