What is integrated wall?
Integrated wall is an integrated whole house decoration solution proposed in 2009 for home decoration pollution and cumbersome processes. It has two steps from production to finished product, the first step is the extrusion equipment to extrude the substrate board, the second step is the film.

So, as consumers are most concerned about the issue: how to know the environmental protection of the integrated wall is high or not high? Is the quality good or bad? In fact, it can be pursued from these two aspects - the quality of the raw materials used in the substrate board and the coating process of the integrated wall.

Selection of substrate board
The substrate board is the selection of environmentally friendly materials through high temperature composite, in this high temperature process, the composition of the substrate board of a variety of raw materials have been changed material properties, containing volatile chemicals have all been released after high temperature, so the selection of qualified raw materials produced by the integrated wallboard substrate board itself can be very environmentally friendly. For example: nano fiber, solid wood integrated wall and so on.

However, the key to the health and environmental protection of the integrated wall is not the choice of substrate board, but the coating process of the integrated wall.

Integrated wall coating process classification
According to the adhesive and process of coating selection, it is generally divided into PUR hot melt adhesive coating and cold adhesive coating.
PUR hot melt adhesive coating VS cold adhesive coating
According to the above figure, it can be concluded that the PUR hot-melt adhesive coating process has higher working efficiency, better glue control and long-term use performance than cold adhesive coating, and the most key is that its environmental protection is stronger.
Therefore, compared with the cold adhesive coating process, PUR hot melt adhesive as a reactive adhesive has the following advantages:

01
Solvent-free, unlike solvent-based adhesives that need to have a drying process, there is no environmental pollution and poisoning problems due to solvents, high environmental performance: no benzene, no formaldehyde.
02
Excellent resistance to heat, cold, water vapor, chemicals and solvents. The bonding strength is greatly improved.
03
Good operability. The sticky body can be fixed in a short time, greatly improving the work efficiency, and the production efficiency of the hot glue coating machine is 3-4 times that of the cold glue process.

Therefore, the integrated wall using PUR hot melt adhesive coating process is the trend of future development. The real realization of odorless, benzo-free, formaldehyde-free environmental protection integrated wall starts from the use of PUR hot adhesive coating process; Start with the choice of professional high-quality coating equipment.
