TH23627A3 - Thread for extruding hygroscopic substances - Google Patents

Abstract

Thread for extruding hygroscopic substances It is a set of threads consisting of 7 different threads arranged alternately connected together. For extruding the mixture of water-absorbing substances into strips. The said thread is used For inserting into the shaft of a twin-screw extruder to produce hygroscopic substances in the form of long, continuous strands. The composition of the hygroscopic substance is evenly distributed.

There is a hole in the middle of the thread for insertion. with extruder shaft The distance between the spiral ridges is 1 time the thread diameter. and the length of the thread is 0.5 times the diameter of said thread. Thread type 6 (8) is a thread for transporting substances. The outside looks like a circular spiral. In the center of the spiral there is a hole for inserting into the extruder shaft. The distance between the thread ridges is 1 times the diameter. center of thread and the length of the thread is 0.5 times the diameter of said thread. Thread type 7 (9) is a thread that helps increase the pressure of the substance inside the extruder so that the substance can Can flow through the open end to form a line. There is a hole in the middle of the thread for inserting into the extruder shaft. The distance between the thread ridges is 0.5 times the diameter of the thread. and the length of the thread is 1.5 times the diameter of said thread. which has specific characteristics: There is a connection arrangement of spirals that serve to transport substances to transport raw materials, namely type 1 (3), number 1014.
