Abstract

종래에는 폴리에틸렌(POLYETHYLENE) 연속 기포의 가교발포체를 BATCH TYPE인 가압프레스로 가열 가교한 후 2차 MOLD에서 가열발포하여 압착롤라로 압착 CELL를 오픈시키는 공법으로 제조하였으나 이는 작업시간과 일의 능률이 떨어지는 결점이 있었다. 이러한 결점을 보완하고 연속으로 제조 가능케한 획기적인 방법으로 그 제조 공정은 수지, 발포체, 가교체, 기타첨가물을 KNEADER에서 혼합후 압출기로 압출성형, 가열발포로에 가교 발포후 압착 롤로 압착하여 CELL을 오픈시켜 연속으로 제조 가능케 하였다.Conventionally, the cross-linked foam of polyethylene continuous foam is heat-crosslinked by press-type press which is a batch type, and then it is manufactured by the method of heat-expanding in the second MOLD to open the press cell with the press roller, but this decreases working time and work efficiency. There was a flaw. As a breakthrough method that compensates for these shortcomings and enables continuous manufacturing, the manufacturing process is performed by mixing resins, foams, crosslinked products and other additives in KNEADER, extrusion molding with extruder, crosslinking foaming with heating foaming furnace and pressing with a press roll to open CELL. It was made possible to manufacture continuously.
