Also prepare for step 4, be heated to 80 degree even more than 100 degree, behind after high-pressure steam comes in, vapor is pressed into plate
Inside material, and ensure that vapor will not internally liquefy.
Step 3, vacuumize, the sheet material that step 2 treats is put into second container, second container is carried out to vacuumize place
Reason, minute processing time 20-30, air pressure are less than 0.1Mpa；Vacuum step fully excludes sheet material inner air, is easy to follow-up
Reacting gas penetrates into.
Step 4, it is filled with high pressure-temperature highly humid air, more than high pressure-temperature damp atmosphere pressure 2Mpa, 130-150 degree,
Humidity 60-90%, it is pressed into the second container that step 3 vacuumizes, stands 30-60 minutes；High pressure-temperature highly humid air can be with
It is directly to be mixed using vapor or high pressure-temperature air with vapor.
Step 5:30-60 minutes are stood in high temperature dry air, below negative pressure 0.9Mpa, promote sheet material internal residual gas
Overflow；Need to discharge the vapor remained in inside sheet material after the completion of step 4 processing, prevent it inside density board
Liquefaction so that denseness sheet material expands.
Step 6. colors in processing, on the surface color.Colored in, recovered according to the original color or lines of denseness sheet material
Its original state.
