Ukuqhathaniswa kwepayipi le-CPE kanye nepayipi le-PTFE

Ukukhetha ipayipi elifanele kuthuthukisa ukusebenza nokuqina kwanoma yiluphi uhlelo lokusebenza. Ngisho noma ukusetshenziswa okukhulu kwamapayipi e-CPE kanye ne-PTFE kusezindaweni zezimboni kanye nezezimoto, ahluka ngobubanzi bamazinga okushisa kanye nohlobo lwamakhemikhali angawaphatha.

Siqhathanise izici eziningi zazo zombili, futhi ukuqhathanisa nakho kuholela esincomweni. Kodwa-ke, lesi sincomo singahluka kuye ngesimo ngasinye njengoba isimo ngasinye sesicelo sihlukile, futhi izinqumo kufanele zenziwe ngokufanele.

Ipayipi le-CPE: (Konke Okufanele Ukwazi)

Ipayipi le-Chlorinated Polyethylene (CPE) liyipayipi le-stainless elilukiwe kabili elenziwe ngensimbi engagqwali esezingeni eliphezulu. Ipayipi langaphakathi le-polyethylene eli-chlorinated linikeza ukuhambisana koketshezi lwe-borax race.

Ipayipi le-CPE livame ukusetshenziswa ngenxa yekhono lalo lokusingatha amazinga okushisa ahlukahlukene kanye nokuguquguquka kwalo nokuqina kwalo, okuwusizo kakhulu ezindleleni zokusebenza zezimoto nezimboni.

Izinto kanye nesakhiwo:

Ipayipi lakhiwe ngendwangu yangaphandle yensimbi engagqwali ukuze imelane nokuklwebheka nokugqwala; lihlanganiswe neshubhu yerabha yangaphakathi ye-polyethylene ene-chlorine ehlanganiswe nendwangu yangaphakathi ye-nylon, okwenza imelane nakakhulu namakhemikhali athile.

Lezi zendlalelo ze-CPE ziyenza imelane, kodwa uma kukhulunywa ngokuphatha amakhemikhali anamandla kakhulu - i-CPE ayithenjwa kabanzi njengoba ingamelani nawo ngokuphelele.

Ipayipi le-PTFE:

I-PTFE iyindlela eguquguqukayo futhi eqinile esikhundleni samapayipi enjoloba futhi ihlanganyela izici ezithile ezijwayelekile namapayipi e-CPE. I-PTFE - i-polytetrafluoroethylene isetshenziswa njenge-liner yamapayipi aboshwe ngensimbi engagqwali noma amapayipi enjoloba ukuze aqine kakhulu ekushintsheni kwezinga lokushisa namakhemikhali, okwenza aqine kakhulu futhi aqine kakhulu.

Izinto kanye nesakhiwo:

Amapayipi e-PTFE anolwelwesi lwe-PTFE olusetshenziswa kakhulu ezitsheni zokupheka ngezinjongo zokumboza. Ngokwesimo, i-PTFE isetshenziswa nakumadivayisi ezokwelapha kanye nokukhiqizwa kwama-semiconductor. Imikhiqizo eyahlukahlukene efana nama-shaving blades, izitsha zamakhemikhali, ngisho nezibuko zamehlo zidinga i-polytetrafluoroethylene coating.

I-PTFE akuyona insimbi noma irabha, kodwa iyi-polymer ye-thermoplastic enesici esishelelayo.

Izinga lokuncibilika kwale nto liphezulu kakhulu futhi cishe limelana nawo wonke amakhemikhali, kufaka phakathi amanye anamandla.

Yikuphi Okungcono Futhi Kungani:

· Ukukhetha i-CPE kune-PTFE:

Ipayipi le-CPE lifanele amazinga okushisa aphakathi nendawo futhi linikeza ukumelana okuhle noketshezi lokwenziwa, njengezithambisi, amafutha okugcoba, namafutha. Lingamelana namazinga okushisa aphakathi nendawo afinyelela ku-150°C, okusebenza kahle ezinhlotsheni eziningi zezimoto nezimboni.

Ipayipi le-CPE linikeza ukuguquguquka okukhulu kunepayipi le-PTFE, ukuze lisetshenziswe kalula ezindaweni ezixineneyo. Futhi, intengo yepayipi le-CPE iphansi kunele-PTFE, okunikeza inzuzo eyengeziwe yokusebenza kahle kwezindleko ngokumelana okwanele kwezinga lokushisa kanye namakhemikhali.

· Ukukhetha i-PTFE kune-CPE:

Ipayipi le-PTFE liyinguqulo eqinile kakhulu futhi ephikisanayo yepayipi le-CPE, ngakho-ke lihlala isikhathi eside ezimbonini ezidinga ukulawulwa kokushisa kanye nokungangeni kwamakhemikhali.

Ipayipi le-PTFE lingamelana namazinga okushisa asukela ku--65°C kuya ku-260°C kanye nokucindezela kwe-psi okufika ku-5500. Ngokuphathelene namakhemikhali, i-PTFE iyahola njengoba inesembozo esikhethekile esenza ingasebenzi cishe kuzo zonke izinto.

Ukumelana okuphezulu kwamakhemikhali kanye nokushisa kusho ukuthi amapayipi e-PTFE azoguga kancane kakhulu kune-CPE.

Uma udinga amapayipi okudlulisa amakhemikhali anamandla, njengezinyibilikisi emkhakheni wephethiloli, okufuthwa ngezibulala-zinambuzane, imithi, kanye nezicelo zezindiza, i-PTFE ingcono kune-CPE.

Ungayikhetha Kanjani Ipayipi Elifanele Wena?

Ukukhetha ipayipi elifanele wena kuhilela ukuhlaziywa kwezidingo zakho ezithile kanye nezimo zokusetshenziswa. Izici ezintathu eziyinhloko zizothonya isinqumo sakho:

1. Ukuchayeka Kwamakhemikhali

2. Izinga Lokushisa Eliphakeme

3. Izindleko vs. Ukusebenza

Uma udinga amapayipi amakhemikhali anamandla futhi aqinile, ukukhetha okufanele kuwe kuzoba yipayipi le-PTFE elinconywa abakhiqizi bamapayipi e-PTFE njengePassion Hose.

Ngaphezu kwalokho, izinga lokushisa loketshezi lizonquma ukuthi iyiphi ipayipi efaneleka kakhulu. Uma ingaphansi kuka-150 °C, ipayipi le-CPE lizoba ngcono kunepayipi le-PTFE.

Ekugcineni, kufanele ukhethe phakathi kwezindleko nokusebenza kahle. Ngisho noma ipayipi le-CPE linikeza ukusebenza kahle kwezindleko kusenesikhathi, ungase ukhethe ukusebenza kwesikhathi eside nokuqina okunikezwa yipayipi le-PTFE.

Isiphetho

Uma sikhuluma ngenketho engcono, khona-ke kuyiqiniso ukuthi akukho ukukhetha okunezinzuzo nezimbi. Yonke inketho iyinhlanganisela yakho kokubili. Ngokufanayo, ukukhetha phakathi kwepayipi le-CPE nele-PTFE kulinganisela ukuchayeka kwamakhemikhali, amazinga okushisa aphezulu, kanye nokuhlaziywa kwezindleko vs. kokusebenza. Ukucabangela lezi zici kuzokunikeza izinto ezihlangabezana nezidingo zakho futhi zinikeze ukuqina kwesikhathi eside.

Ucabanga nge-Hose ngezidingo zakho ezithile?

Uma unesifiso sokuthola amapayipi e-PTFE noma e-CPE asezingeni eliphezulu, i-Passion Hose yigama elithembekile emakethe elivelele njengomunye wabakhiqizi abathembekile nabathembekile be-PTFE, enefa lokusebenzela amakhasimende ethu iminyaka engaphezu kwengu-15.
