Why Using Dehumidification Resin Dryer Machine?
The coastal areas of China belong to maritime climate and the annual relative humidity is over 75%RH, easy to cause the excessive moisture of resin particles. As the moisture and hygroscopicity of the resin particles are different from those of the previous production process, the particles tend to generate many problems such as bubbles, silver streaks, poor transparency, cracks, insufficient durability, flowing marks, poor stability in size control, etc. during the molding. (according to the research report issued by state plastic institute SPI, the moisture of molding plastic particles should be reduced to 0.02%) most of the plastic raw materials are hygroscopic.
So when they are taken out of the package and exposed to the air, they begin to absorb moisture. In the case of the maritime climate, the regular hot-air hopper dryer will take moisture in the air to materials, so it can not prevent materials from absorbing moisture. Using Soxi resin dryer machine can solve these problems.
