Description
Technical field
The utility model relates to PET spinning reciprocating extruders.
Background technique
With the rapid development of Macromolecular materials industry in Plastics Processing Industry, the exploitation of reciprocating single-screw intermixing extruder
Using attracting people's attention increasingly.Single, double screw extruder in squeezing out industry in the highest flight has been permitted various performances not
It is able to satisfy the modified requirement such as blending, filling, enhancing, toughening, some high-tech is produced using reciprocating single-bolt extruder and contains
Amount, high value-added product are increasingly becoming a kind of trend, and in the process of any polymer, imparting polymer is certain to be added
Work characteristic assigns the specific service performance of product, it is often necessary to which the blending or polymer carried out between different polymer is helped with various
Mixing between agent, pigment overcomes its molecule to ask issuable partial gel particle or non-molten resin.And reciprocating single spiral shell
Bar intensive mixer has the characteristics that uniform shearing just, high dispersive, high filling, stretches melt.And it combines single, double screw rod and squeezes
Out the advantages of machine.Unique working principle, in addition a whole set of screw thread composition element and corollary equipment, keep its application wider
It is general, on a machine, it can accomplish mixing, mixing, plasticizing, dispersion, shearing, stretching, degassing, granulation, so that melt is in machine
