Eminyakeni engama-20 edlule, amapayipi amasha epulasitiki asetshenziswe kakhulu ezindaweni ezithatha amanzi zikamasipala, igesi kanye nezizinda zokuphehla amandla. Ikakhulukazi ngokuqhubeka nokwenza kahle kanye nokuqanjwa okusha kobuchwepheshe be-polyethylene polymerization, ziya ngokuya ziba namandla aqinile ezinto ze-polyethylene. Ukuze kuqhutshekwe nokwandisa ububanzi bamazinga okucindezela amapayipi epulasitiki, ikakhulukazi eminyakeni yamuva, ngocwaningo lobuchwepheshe bemikhakha eyahlukene, ubuchwepheshe obuhlanganisiwe bensimbi-plastic owethulwe buye baxazulula ngempumelelo izinkinga zamapayipi e-polyethylene (PE) ngokwezinga lokucindezela, anti- ukugqwala, kanye nobubanzi obusebenzayo bokujikeleza. Isetshenziswa kuhlelo olubanzi lwezinhlelo zokuthutha uketshezi.
Isakhiwo: Lo mkhiqizo uwuhlaka oluqinisiwe olunongqimba oluyisisekelo locingo lwensimbi olunenxeba eliphezulu ngokuqhubekayo ngemva kokwelashwa kokumbozwa, kanye neglue ekhethekile encibilika ngokushisayo kanye nepulasitiki kuhlanganiswe kube yipayipi lonke ngendlela yokubumba i-extrusion.
Ukusebenza komnotho kwepayipi
Isebenzisa i-polyethylene ephezulu kakhulu njengezinto zesendlalelo sangaphakathi nangaphandle, ipayipi lensimbi lensimbi le-polyethylene eliyinhlanganisela yepulasitiki linokusebenza okuhle kakhulu kwemikhiqizo yamapayipi e-polyethylene. Ngenxa yomphumela we-steel skeleton, ipayipi eliyinhlanganisela yezinga elifanayo lokucindezela linobukhulu obuncane bodonga kunamapayipi epulasitiki ahlanzekile. Ukujikeleza okusebenzayo kwe-агеа kukhudlwana, futhi ukumelana nokugqwala okuhle nokumelana nokuguga kuqinisekisa ukuthi impilo yesevisi yepayipi ingaba yiminyaka engama-50, okuthuthukisa ngempumelelo ukusebenza komnotho wepayipi.
Qinisa uhlaka lwamathambo ukuze ucindezele ngempumelelo imifantu
Ukusetshenziswa kongqimba oluyisisekelo lwensimbi olunamandla amakhulu njengohlaka lwamathambo oluqinisayo kuvimbela ngempumelelo ukukhiqizwa kokuqhekeka okungamahlalakhona kanye nokusakazeka ngokushesha kokuqhekeka kwezinto ze-polyethylene, futhi kunamandla acindezelayo aphezulu (umfutho wepayipi lamanzi ufinyelela ku-З.5МРа) kanye nomuntu ongamazi сгеер ukumelana, Ukumelana nomthelela Ophakeme, kanye nezinkomba zayo zokusebenza аге ukuphakama kwamapayipi e-polyethylene.
