Touch some mechanical admixtures.The influence containing water problems of especially material is very big.Some plastic resins and auxiliary material are in storage period
Between be very easy to absorb air in moisture or some plastic products production need to guarantee water content extremely low in material, this
When we to material be dried pretreatment just seem increasingly important.In the production of certain plastic products, moisture is contained in material
Can be squeeze out finished product occur bubble or or the reason of the apparent masses problem such as speckle, the performance that product can be reduced when more serious refers to
Mark.So former in ABS, polycarbonate, polyamide, poly-methyl methacrylate acyl and the cellulose acetate of production moulded products etc.
Material, must carry out drying process of drying before manufacture.But presently, there are following problems: on the one hand, when to twin-screw extrusion material
It is only simple to illustrate by raw material when dry, the drying condition of inquiry material is also removed, goes to give material dry accordingly pre-
The method of processing does so inadequate scientific and precise, because material transportation is all easy to produce impurity during storing, impurity is deposited
In the effect that also will affect dry materials；On the other hand, existing drying machine is all individualism, it is desirable to twin-screw extrusion object
Material just needs for material to be placed individually into drying machine to be dried when being pre-processed, then the material being dried is taken
It puts into double screw extruder out, needs manual operation, such process not only heavy workload, and also it is time-consuming very long and from drying
Material touches outside air during being taken out in material and investment double screw extruder in machine, can also absorb certain water
Point.In addition, the control of temperature is also critically important during dry materials, temperature is excessively high to will lead to material deformation, temperature too it is low again
It will affect drying effect, requirement of the different materials to temperature is also different.Therefore, how the drying of very good solution material
