Likuphi ipayipi lamanzi le-HDPE?
Ngenxa yezinzuzo zayo eziyingqayizivele,Ipayipi lokuhambisa amanzi le-HDPEisetshenziswa kabanzi ekwakhiweni kobunjiniyela ipayipi lokuphakela amanzi, ipayipi lokudonsa amanzi elingcwatshwe, ukwakhiwa kobunjiniyela ukufudumeza okuphakathi, ipayipi legesi, imishini yokushisela nokuxhumana nokugcinwa komkhono ongangeni manzi, ipayipi lebanga lezimboni, ipayipi lezolimo nemfuyo, njll. Isetshenziswa kakhulu ekunikezeni amandla, ezemvelo. igesi nokunisela ngezolimo emadolobheni amakhulu.Izakhiwo eziqinile eziqinile zenza umkhiqizo usetshenziswe kabanzi.Izakhiwo eziqinile zepayipi lokuphakela amanzi le-PE zizokwethulwa ngokuningiliziwe ngezansi.
Kuzicelo zamapayipi okuhambisa amanzi e-HDPE, izinto ze-polymer zinezakhiwo ezibonakalayo ezidingekayo.Izakhiwo ezibonakalayo zama-polymers amaningi ziphakeme kunezakhiwo eziqinile zezinye izesekeli ze-HDPE.Amakhasimende amaningi akholelwa ukuthi uma sisebenzisa izesekeli ze-HDPE njengamapayipi okuhambisa amanzi, asinandaba nempahla eqinile njengenkomba yokusebenza, kodwa lapho sisebenzisa izinto zokusetshenziswa, sidinga izakhiwo ezibonakalayo zezinto ze-polymer.
Ngokuvamile, kukhona amafilimu ancipha ukushisa namafilimu ashwabeneyo, adinga izakhiwo eziqinile eziqinile zezinto zokusetshenziswa.Eqinisweni, imikhiqizo ethile ye-HDPE isesekeli ngokuvamile inezakhiwo eziqinile ezingaba ngu-200%.Njengohlelo lokusebenza lwesisetshenziswa sokudonsa se-HDPE, lesi sibalo sifanelekile futhi izakhiwo eziqinile zinhle ngendlela emangalisayo.Ngenxa yokwelula, insiza yepayipi lokuphakela amanzi le-HDPE akungabazeki ukuthi.
Iyiphi indima edlalwa yi-HDPE ekuqineni kwamapayipi amanzi?
Lapho kusetshenziswa ama-polymers njengezinto zokwakha, amakhasimende amaningi awanayo intshisekelo ezicini ezidingekayo zemishini.Ezisetshenziswa eziningi zama-polymers, izakhiwo zemishini ngokungangabazeki zibaluleke kakhulu kunezinye izakhiwo ezibonakalayo.Kuzo zonke izinto ezaziwayo, ama-polymers anohlu olubanzi kakhulu lwezakhiwo zemishini.Lokhu kungenxa yokuthi ama-macromolecules akhiwa ama-molecule amaketango amade anezindawo ezibalulekile zokuphumuza ukunyakaza kwamangqamuzana.Uma ukuphakama kwe-polymer kuphezulu, ukuphakama kokuphuka kwe-PE evamile kungu-90% kuya ku-950% (i-linear low density polyethylene LLDPE inobude obuphakeme).Ngenqubo ekhethekile yokukhiqiza, inani lobude obuqinile bezinye izinto zokwakha lingaba ngaphezu kuka-1000%, futhi ukwelulwa ngesikhathi sokuphumula kwezinto ezivamile ze-polymer kungafinyelela ku-50% -10%.Ngokuvamile, ifilimu eshwabene nokushisa, ifilimu eqinile, njll., izici eziqinile zezidingo eziphakeme zezinto ezibonakalayo.
Ukusebenza kwepayipi lokuhambisa amanzi le-HDPE kuhle, akulula ukulimaza, impilo ende yesevisi.Ikakhulukazi efanele izicelo zokuhlinzekwa kwamanzi.Ukugcinwa kwenziwa ngesikhathi sokusetshenziswa ukuze kunwetshwe isikhathi sokusetshenziswa.
