Description
Technical field
The utility model relates to a kind of filer element type fondant filter, belongs to polymer production technical field of auxiliary equipment.
Background technology
In the processes such as synthetic fiber spinning, injection moulding, bottle blowing, improve the quality of products minimizing substandard products, enhances productivity to reduce costs, and carries out filtration to be absolutely necessary step to polymer.Due in polymerization process, the existence of the solid impurity be mingled with in unreacted monomer, raw material, polymer gel etc., and in high speed spinning process, spinline diameter is little, and need powerful stretching; In injection moulding, bottle blowing process, the light transmittance of the foreign materials away such as solid impurity, gel product.Therefore, the purity improving polymer ensures that next procedure is normally carried out and one of key factor of end product quality.
So high speed spinning must install prefilter additional, to improve the purity of melt, reduce the burden of filter course in filament spinning component. extend life cycle. reducing the waste silk produced because exchanging filament spinning component, which enhancing quality and again reducing cost.
Often through having reacted at polymer polymerizing or having arranged filter before next procedure, but the filter of existing routine normally adopts screen cloth to filter, although this filter type eliminates impurity and gel particles to a great extent, but due to the defect of himself structure, filtering accuracy cannot further improve, the impurity less for particle diameter and gel particles then cannot realize filtering and stopping, and the impurity of these small particle diameter and gel particles can be brought into next procedure by melt; Meanwhile, in filter process, larger pressure can be produced, have higher requirement to the structure of filter.
Based on this, make subject application.
