Mainly some very hygroscopic materials. Generally speaking, the processing of PET must use a dehumidifying dryer. PBT and nylon are best used in areas with high air humidity. Other plastics can basically be dried.
Why does the PET dehumidification dryer windmill often alarm?
First, it depends on what method is used to dehumidify, what is the structure, there are two kinds of effects on the market, (rotary dehumidification zhi and double tower switching dehumidification),
Second, whether the raw material is new material or broken recycled material, if it is recycled material, the windmill should increase the air volume and increase the flow of hot air.
3. Drying windmills use high temperature windmills. Because the drying temperature of pet is 160-180 degrees, windmills above 200 degrees should be selected.
Fourth, because of the increase in cooling, it should be one-third larger than that of ordinary raw material models to fully cool down
Of course, you have to see the actual scene to make an accurate judgment.
