Izinto ze-Polythene, ezivame ukubizwa ngegama elithi polythene noma i-polyethylene, zakha umgogodla wezinqubo eziningi zokukhiqiza nezokupakisha zesimanje. La ma-polymer ahlukahlukene akhiqizwa ngezinga elihlukahlukene lamandla kanye nezakhiwo, okuvumela onjiniyela nabakhi bezimikhiqizo ukuthi bakhethe izinto ezinokuqina okuthile komshini, okokushisa, nokumelana namakhemikhali. Igama elibanzi elithi "izinto ze-polythene" lihlanganisa izinhlobonhlobo ezifana ne-expanded polyethylene, i-high density polyethylene, kanye nezingxube ezivame ukubekwa ngaphansi kwe-pp polyethylene ne-polyethylene polythene ezinhlu zokuhweba. Ukuqonda izinto ze-polythene kudinga umbono wesayensi yezinto kanye nolwazi lwezindlela zemboni, ngoba ukukhetha kuthinta impilo yomkhiqizo, ukusebenziseka kabusha, kanye nokonga izindleko. Lesi sethulo sibeka isiteji sokubuyekezwa okuningiliziwe kwezinhlobo, izicelo, izinzuzo, kanye nokuqanjwa okusha kwezobuchwepheshe be-polythene esikhathini esizayo.

Izinto ze-Polythene zitholakala ngezinhlobo eziyinhloko eziningana, ngayinye enezici zokusebenza ezihlukile. I-Low density polyethylene (LDPE) inikeza ukuguquguquka okuhle kakhulu, ukucaca, nokuqina, okuyenza ilungele amafilimu nokupakishwa okuguquguqukayo; i-expanded polyethylene (EPE) iyinhlobo eyenziwe ngomoya esetshenziselwa ukugcwalisa nokuvikela ukushisa. I-High density polyethylene (HDPE), evame ukubizwa ezinhlu zezimboni njenge-high density polyethylene noma i-HDPE, inikeza ukuqina okungcono kakhulu, ukumelana namakhemikhali, namandla okuthwala umthwalo ezicelo ezifana neziqukathi nemibhobho. Ngaphezu kwalokhu, izinhlanganisela nama-copolymers afana ne-linear low density polyethylene (LLDPE) kanye nezakhiwo eziguquliwe ezibhalwe njenge-pp polyethylene noma i-polyethylene polythene kumakhathalogi okuthenga zandisa indawo yokuklama, zivumela izixazululo ezenziwe ngendlela efanele izinqubo zokukhipha, ukubumba ngomoya, nokubumba ngomjovo. Ukukhetha phakathi kwe-LDPE, i-HDPE, i-EPE, nezinye izigaba kuncike ezicini zemishini ezidingekayo, indlela yokucubungula, izindaba zokulawula, kanye nokuhlaziywa komjikelezo wempilo.

Enye yezinto ezisetshenziswa kakhulu izinto ze-polythene ukuba zipakiswe, lapho izindleko, izakhiwo ezivimbayo, kanye nokwakheka kubalulekile. Amashidi enziwe nge-LDPE ne-LLDPE ahlinzeka ngokwelula, ukucaca, nokumelana nokudabuka ukupakisha okuguquguqukayo, kanti i-HDPE ihlinzeka ngokuqina okwakhelwe amabhodlela, amagayelani, namadubhu ezimboni. I-polyethylene eyandisiwe ivame ukusetshenziswa njengokuvikela okuthambisayo kwezinto zikagesi, izitsha zengilazi, namathuluzi okunemba ngenxa yesakhiwo sayo se-foam esithambisa ukushaqeka. Abakhiqizi abaningi bahlanganisa izendlalelo noma bahlanganise izigaba ezahlukene ze-polyethylene ukuze balungise izakhiwo ezifana nokuvimbela umoya-mpilo, ukumelana nokubhoboza, kanye nokubopha. Lapho bakha izinhlelo zokupakisha, onjiniyela kufanele bacabange hhayi kuphela ngezindleko zezinto nokusebenza, kodwa futhi nokusingathwa kokuphela kwempilo kanye nezikhuthazo zokugaywa kabusha.

Emkhakheni wokwakha, izinto ze-polythene zidlala izindima ezahlukahlukene kusukela ezivimbeleni-nkungu kuya kuma-geomembranes nezinhlelo zamapayipi. Ama-geomembranes e-HDPE ahlinzeka ngezixazululo zokugcina ezihlala njalo ezindaweni zokulahla udoti, imisebenzi yokumba izimayela, nokugcina amanzi ngenxa yokumelana kwawo namakhemikhali kanye nokungangeni kwawo kalula. Ama-films e-polythene asetshenziswa njengezivimbeleni-mongi ngaphansi kwezindonga eziyisisekelo kanye nophahla ukuvikela izakhi zesakhiwo ekuthwalweni kwe-nkungu. Imikhiqizo ye-polyethylene eyandisiwe ingasebenza njengokufakelwa okufudumele noma ukupakisha okuvikelayo kwezingxenye zokwakha ezizwelayo kumongi noma ukulimala komshini. Ukuguquguquka kwe-polyethylene polythene ekukhiqizeni nasekuqinisweni kwamashidi kwenza kube ukukhetha okonga izindleko kuzo zonke izinhlelo eziningi zokwakha, futhi ukumelana kwayo nokubola kwezinto eziphilayo kunikeza impilo ende yesevisi ezimweni ezinzima.

Ezolimo zizuzwa izinto ezikhethekile ze-polythene kumafilimu okugquma umhlabathi, izembo zama-greenhouse, imibhobho yokunisela, nokugoqa okwe-silage. Amafilimu e-polyethylene aphansi ngokuminyana naphansi ngokuminyana anikeza abalimi izinketho zokudlulisa ukukhanya, ukulawula izinga lokushisa lomhlabathi, nokugcina umswakama ngenkathi ehambisana nokumelana nokudabuka nokuzinza kwe-UV.
