본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 사용되는 성형관의 예시단면도이고,1 is an exemplary cross-sectional view of a forming tube used in the present invention,

제2도는 본 발명에 사용되는 성형관을 구성하는 팽창관의 예시단면도이다.2 is an exemplary cross-sectional view of the expansion tube constituting the forming tube used in the present invention.

Claims (2)

조사가교시킨 튜브를 별도의 장치에 의해 공급되는 고온에서 강도가 크고 신율이 작은 얇은 폴리에스텔레이프로 감싸서 도입평행부와 경사부 및 배출평행부로 형성되어 단계적으로 직경이 확장된 팽창관을 여러개 결합하여 구성시킨 다단계 성형관을 통과시키면서 성형관내에서 비동점이 높고 물과의 상용성이 좋은 고급알코올에 의해 가열하고, 튜브의 내부에는 압축공기를 공급하여 가열된 튜브를 테이프내에서 충분히 팽창시켜 요구하는 크기의 직경 즉, 다단계 성형관의 마지막 팽창관의 배출평형관의 내경크기로 확장시킨후 급냉에 의해 고화시키고 테이프를 분리제거하여 권취하므로서 편심률과 길이방향의 연신이 작고 확장된 튜브의 외면이 양호한 제품을 수축률 75%이상이 되도록 연속제조할 수 있는 플라스틱 튜브의 제조방법.The cross-linked tube is wrapped in a thin polyester fabric with high strength and low elongation at high temperature supplied by a separate device, and is formed of an introduction parallel portion, an inclined portion, and an exhaust parallel portion, thereby combining a plurality of expansion tubes expanded in stages. Passing the formed multi-stage forming tube and heating it with high alcohol having high boiling point and good compatibility with water in the forming tube, and supplying compressed air to the inside of the tube to expand the heated tube sufficiently in the tape to size required After expanding the diameter of the multi-stage forming tube to the inner diameter of the discharge equilibrium tube of the last expansion tube, solidifying by quenching and winding by separating and removing the tape, the eccentricity and elongation in the longitudinal direction are small, and the outer surface of the expanded tube is good. A method for producing a plastic tube that can be continuously manufactured so that the product has a shrinkage of 75% or more. 제1항에 있어서, 팽창시킬 튜브의 직경보다 1-2mm 큰 직경의 도입평행부(2)와 경사도의 경사부(3)와 도입평행부(2)보다 1.2-1.4배 큰 직경의 배출평행부(4)로서 형성된 팽창관(1)을 여러개 결합하여 구성시킨 다단계 성형관(A)을 통과시킴으로서, 수축률 75%이상의 열수축성 튜브를 연속제조할 수 있는 플라스틱 튜브의 제조방법.2. The inclination and inclination of the leading parallel part 2 having a diameter of 1-2 mm larger than the diameter of the tube to be expanded By passing through the multi-stage forming pipe (A) formed by combining a plurality of expansion pipe (1) formed as a discharge parallel portion (4) of 1.2-1.4 times larger diameter than the inclined portion (3) and the introduction parallel portion (2) of A method for producing a plastic tube capable of continuously manufacturing a heat shrinkable tube having a shrinkage of 75% or more. ※참고사항:최초출원 내용에 의하여 공개하는 것임.※ Note: This is to be disclosed based on the first application.
