The fragrant board is made of crop straw scraps as the main raw material, MDI glue and functional additives, and is made at high temperature and high pressure. It is not only flat, symmetrical and firm in structure, but also has the characteristics of good dimensional stability, high strength, environmental protection, flame retardant and weather resistance.
It also has excellent processability and surface decoration performance, and is suitable for all kinds of surface decoration treatment and mechanical processing, especially special-shaped edge processing. Compared with particleboard, it has obvious advantages. It can be widely used instead of artificial board and natural wood.
The raw materials of fiberboard and particleboard in the market are all wood, and the reason why there are E0 grade and E 1 grade in it is mainly an adhesive. The traditional binder of particleboard is urea-formaldehyde resin.
Polyurethane is mainly used as the insulation layer of refrigerator, such as soles and spandex. This kind of structure is very stable, and there is no formaldehyde, so this kind of board is really formaldehyde-free, which changes the traditional system. However, there is a layer of wax on the surface of crop straw, so traditional adhesives can't make crop straw.
So he can only use polyurethane glue, and he has to react with cellulose in crop straw, so only it can stick together, which determines its environmental protection. In addition, the biggest feature of this kind of straw board is that traditional fiberboard has to grind wood fibers, so there is a lot of wastewater discharge, just like papermaking.
Moreover, this model has no toxic and harmful waste discharge, so its production process is also environmentally friendly.
