Is bamboo wood fiber integrated wallboard material toxic? How to judge the quality?
Is bamboo wood fiber integrated wallboard material toxic? How to judge the quality?In fact, if the quality is good, the bamboo-wood fiber integrated wallboard can be completely non-toxic and harmless, and truly achieve zero formaldehyde; if the quality is low, it will not only affect the service life, but also volatile harmful substances and affect the health of the family! The quality can be judged by the following points:
1. The quality of the substrate board itself: The quality of the bamboo-wood fiber integrated wallboard is related to the formula of each factory. Many people see color at first glance, but color is not important, and pigments are based on toning. But it looks gray and extremely green, which is definitely a poor second- and third-grade material. Then the average person will look at the thickness, but in fact the thickness has no reference significance, the thickness cannot determine the strength. Some thick plates are actually foamed more fully, the actual production is less material input, and the cost is lower, so his plate is softer, the strength is much worse, and the problem is that the thermal expansion and contraction are more obvious, and the service life Shorter.
There is also a coextrusion problem. The co-extrusion edge is actually to strengthen the mother groove at the seam joint to make it stronger, and has no effect on nailing and screwing. Co-extrusion requires the manufacturer to add another small device, which can be considered as an increase in cost, so many manufacturers do not do it.
We can see that the lower edge is covered with a layer of hard material to make it stronger and more resilient, which is a small distinction.
2. The quality of decorative film materials: decorative films include ordinary PVC decorative films, water-based PVC decorative films, PP decorative films, etc. These prices are very different. Basically, they are all ordinary PVC decorative films on the market, and the price of PP films is basically the same Due to the price of plates. In terms of quality, PP decorative film is the best, but the price is very high, according to their needs!
3. The difference of laminating technology: There are hot-melt adhesive technology and cold-gluing technology. The difference can be seen in the table below. It is obvious that PUR hot-melt adhesive is the best
