The difference between Direct paste and compound paste

?? Direct paste process and compound paste process are the two commonly used processes for plywood and ecological panels.

??Direct paste process is the first base material glue, and then and sheet group blank after hot pressing. Then after cooling and sanding, the impregnated film paper is added, and then hot-pressed after forming a blank.

??Tips:Substrate gluing + Sheet - put it here together - Hot pressing - Cooling - Sanding - Impregnated film paper - put it here together - Hot pressing - Cooling - cutting extra edges - Sub-inspection - Packaging and warehousing

??Compound paste process is first sheet and impregnated film paper group blank hot pressing, and then press paste good film paper sheet and substrate group blank after hot pressing together, and finally made after cooling trimming.

??Tips:Sheet + impregnated film paper - put it here together - hot pressing - Substrate gluing - put it here together - hot pressing - cooling - cutting extra edges - inspection - packaging and warehousing

??From the process, it looks as if the direct paste process is more simple, compound paste process is more complex, does it mean that the compound paste of the board to be better?

??In fact, just the opposite, the direct paste of the board to be better than the compound paste, this is because the direct paste process on the core board of the flatness requirements are very high.Slightly inferior core boards cannot use the direct bonding process, and the direct paste of the board is not easy to carbonize the phenomenon, more durable.

??Relative to direct paste, compound paste process is later appeared, although looking at the process is more complex, but it is lower than the requirements of the material direct paste, the details are not as good as the direct paste board, Overall, composite boards are not as good as straight boards.

??However, the compound paste board is lower than the price of direct paste board, which is also its advantage.
