Claims (1)

분말의 고밀도 폴리에틸렌을 20―100mesh의 망체로 분류하여 150±5℃의 온도로 5분간 에열하고, 상온으로 냉각한후 파이프상의 형틀에 충진시키고, 100―120℃의 온도로 약 30분동안 소결하여 기공율이 20―80%가 되게하는 것을 특징으로 하는 다공성 파이프의 제조방법.The high-density polyethylene of the powder is classified into a 20-100 mesh mesh and is annealed at a temperature of 150 ± 5 ° C. for 5 minutes, cooled to room temperature and filled in a mold on a pipe, and sintered at a temperature of 100-120 ° C. for about 30 minutes. A method for producing a porous pipe, characterized in that the porosity is 20-80%. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
