POLYESTER CHIP CONTAINING HIGH GRAVITY MATERIAL AND PREPARATION METHOD THEREOF

摘要

The present invention is a polyester chip manufacturing method containing a high specific gravity material produced by an extruder divided into a first section, a second section, a third section, a fourth section, a fifth section, the first section is a general Melting to melt the polyester by inserting a polyester chip and passing through a time of 8 to 15 seconds while heating to 100 ~ 150 ℃, the second section is passed through a passing time of 3 to 6 seconds while heating to 150 ~ 200 ℃ step; Barium sulfate (BaSO ₄ ) is added as a high specific gravity material in the third section, barium sulfate input step of passing through a passing time of 2 ~ 4 seconds while heating to 200 ~ 240 ℃; Tungsten carbide (WC) injecting a high specific gravity material in the fourth section, tungsten carbide input step of passing through a passing time of 1 to 3 seconds while heating 240 ~ 270 ℃; And it provides a polyester chip containing a high specific gravity material and a method for producing the same comprising an extrusion step of extruding a polyester containing a high specific gravity material while heating to 270 ~ 290 ℃ in the fifth section.
