Ingabe uyazi ngamapayipi e-PE?
2023-07-03
IUlayini wokukhiqiza wepayipi we-PEiyi-spiral die eklanyelwe i-HDPE ne-PP yamapayipi odongeni anobubanzi obukhulu. Lokhu kufa kunezici zokushisa okuncibilika okuphansi, ukusebenza kahle kokuxubana, ukucindezela kwesikhunta esiphansi, nokukhiqizwa okuzinzile.
IUlayini wokukhiqiza wepayipi we-PEyamukela ubuchwepheshe bobunikazi bokulinganisa kanye nezinhlelo zokupholisa, kusetshenziswa ukuthambisa kwefilimu yamanzi nokupholisa indandatho yamanzi ukuze kuhlangatshezwane nezidingo zezinto ze-HDPE ne-PP, okuqinisekisa ukuzinza kobubanzi kanye nokuyindilinga ekukhiqizweni kwesivinini esikhulu samapayipi anezindonga eziwugqinsi.
Ulayini wokukhiqiza wamapayipi e-PE wamukela usayizi we-vacuum oklanywe ngokukhethekile wezigaba eziningiibhokisi lokulawula idigri ye-vacuum, iqinisekisa ukuzinza kwe-dimensional nokujikeleza kwamapayipi e-HDPE ne-PP. Umshini we-extruder kanye ne-traction ulawulwa izilawuli zejubane ezidumile ezivela kwamanye amazwe, ezinokuzinza okuhle, ukunemba okuphezulu, nokuthembeka okuphezulu.
Amapayipi okuhambisa amanzi e-PE enziwe nge-polyethylene ekhethekile njengempahla eluhlaza futhi akhishwa nge-extruder yepulasitiki ngesikhathi esisodwa. Asetshenziswa kumanethiwekhi okuphakelwa kwamanzi asemadolobheni, amaphrojekthi wokunisela nokuphambukisa amanzi, kanye namaphrojekthi okunisela amafafaza ezolimo, alungele ikakhulukazi amapayipi epulasitiki amelana ne-asidi, i-alkali, kanye nezindawo zokugqwala. Ngenxa yokusetshenziswa kokuncibilika okushisayo nokuxhumeka kukagesi okuncibilika kumapayipi e-PE, ukuhlanganiswa kwesixhumi esibonakalayo kanye nepayipi kufinyelelwa, futhi kungakwazi ukumelana ngokuphumelelayo nokucindezeleka okuzungezile kanye nokucindezeleka komthelela we-axial okukhiqizwa ukucindezela. Ngaphezu kwalokho, amapayipi e-PE awafaki iziqinisi zikasawoti wensimbi esindayo, futhi impahla ayinabo ubuthi, ngaphandle kokukala noma ukuzalanisa amagciwane, ukugwema ukungcoliswa kwesibili kwamanzi okuphuza.

Ukusebenza nesikhathi se-Ulayini wokukhiqiza wepayipi we-PEzingamadlelandawonye alawulwa yi-PLC, anokuxhumana okuhle komshini womuntu. Yonke imingcele yenqubo ingasethwa futhi iboniswe ngesikrini sokuthinta. I-extruder ezinikele yokumaka imigqa ingahlanganiswa ukuze ikhiqize amapayipi anezimpawu ezinemibala ezihlangabezana nezindinganiso zikazwelonke.

Ngaphezu kwalokho, amapayipi e-PE awafaki iziqinisi zikasawoti wensimbi esindayo, futhi impahla ayinabo ubuthi, ngaphandle kokukala noma ukuzalanisa amagciwane, ukugwema ukungcoliswa kwesibili kwamanzi okuphuza.
