Abstract
Description
본 발명은 폴리염화비닐 파이프 제조방법에 관한 것으로, 더욱 세부적으로는 건물이나 상하수도의 급수관 및 배수관 또는 전선관으로 사용되는 폴리염화비닐(polyvinyl choride; PVC) 파이프를 제조하는 방법에 관한 것이다.The present invention relates to a polyvinyl chloride pipe manufacturing method, and more particularly to a method for producing a polyvinyl chloride (PVC) pipe used as a water supply pipe and drain pipe or conduit of buildings or water and sewage.
일반적으로 PVC 파이프는 아파트나 고층빌딩 및 상하수도의 급?배수관으로 사용되고 있으며, 비중이 1.43으로 무게는 철판의 1/5, 연관의 1/8, 알루미늄관의 1/2이고, 인장강도는 연관의 3배로써 기계적 강도가 강하므로 운반이 용이하고 파손되는 일이 적다.In general, PVC pipes are used in apartments, high-rise buildings, and water supply and drainage pipes. The specific gravity is 1.43, the weight is 1/5 of the steel plate, 1/8 of the pipe, 1/2 of the aluminum pipe, and the tensile strength of the pipe is increased. Three times the mechanical strength is strong, so easy to transport and less damage.
또한, 관내면이 극히 종밀하고 평골하므로 유해물이 끼지 않고 냄새가 나지 않으며, 수돗물이 탁해지지 않기 때문에 위생적이며 마찰저항이 적어 유량이 동일경의 강관보다 30%정도 더 크고, 무가소제의 경질염화비닐로서 내약품성이 우수하기 때문에 산, 알카리, 유류 등에 침식되지 않으며, 해수나 부식성이 약한 토양중에서도 녹이 생기거나 부식의 우려가 없다.In addition, since the inner surface of the pipe is extremely fine and flat, it does not contain harmful substances, does not smell, and since tap water does not become muddy, it is hygienic and has low frictional resistance, and the flow rate is about 30% larger than that of steel pipe of the same diameter. Because of its excellent chemical resistance, it does not corrode in acid, alkali, oil, etc., and there is no risk of rust or corrosion in seawater or weak corrosive soil.
상기 PVC 파이프는 가열 가공이 자유롭고 접착제에 의한 접합, 접속이 간편 용이하여 고무링 공법 및 TS 공법으로 배관작업을 신속하게 할 수 있고, 내부식성이 강하기 때문에 반영구적으로 사용할 수 있으며, 연관이나 강관보다 가격이 저렴하고 유지비도 금속관보다 저렴하여 경제적이다.The PVC pipe can be used for semi-permanent use because it is free of heat processing, easy to join and connect by adhesive, and can be quickly piped by rubber ring method and TS method, and because it has strong corrosion resistance, it can be used semi-permanently. This is inexpensive and the maintenance cost is also cheaper than that of the metal tube, which is economical.
그러나, 일반적인 PVC 파이프는 제조과정 중 열이나 외부환경에 의해 변형되는 문제점이 발생된다.However, the general PVC pipe is a problem that is deformed by heat or external environment during the manufacturing process.
