Imininingwane yokukhiqiza:
Ipayipi lenhlanganisela yentambo yensimbi eqinisiwe iyipayipi elisha lepulasitiki lensimbi elithuthukisiwe.Lolu hlobo lwepayipi lubizwa nangokuthi ipayipi le-SRTP.Lolu hlobo olusha lwepayipi lwenziwa ngamandla aphezulu ngentambo yensimbi eyimodeli kanye ne-thermoplastic polyethylene njengezisetshenziswa zokusetshenziswa, inethi yocingo lwensimbi njengoba iqiniswe ngepayipi lepulasitiki le-polyethylene, i-high density polyethylene (HDPE) asmatrix, nokusebenza okuphezulu kwe-HDPE modified bonding resin izofaka ifreyimu yocingo. nge-layer yangaphakathi nangaphandle ye-polyethylene ephakeme kakhulu esondelene ndawonye, Ukuze ibe nomphumela omuhle kakhulu oyinhlanganisela.Ipayipi elihlanganisiwe linqoba ukungalungile kokubili kwensimbi nepulasitiki, kuyilapho igcina izinzuzo zakho kokubili, ngoba ukuqinisa insimbi okunamandla aphezulu kufakwe ku-thermoplastic eqhubekayo.
Ipayipi elihlanganisiwe lensimbi eliqinisiwe, ukusetshenziswa kwezinto ezisezingeni eliphakeme kanye nobuchwepheshe obuphambili bokukhiqiza, ukuze kube nokusebenza kwengcindezi ephezulu.Ngesikhathi esifanayo, ipayipi elihlanganisiwe likwazi ukuguquguquka okuhle kakhulu, lilungele ukuthuthwa kwamanzi angcwatshwe ibanga elide kanye nesistimu yepayipi yegesi.Ipayipi le-polyethylene electrofuse lisetshenziselwa ipayipi lensimbi eliqiniswe nge-polyethylene eliyinhlanganisela.Lapho uxhuma, umzimba wokushisa wangaphakathi wokufakwa kwamapayipi usetshenziselwa ukuncibilikisa ipulasitiki yangaphandle yepayipi kanye nepulasitiki yangaphakathi yokufaka ipayipi, ukuze ipayipi nokufakwa kwepayipi kuxhunywe ndawonye ngokuthembekile.
