UM-PE, okanye ipolietile, yinye inye yemiphi wemayithi esetshenziswa emva kokuthi uhlale kwiimbo yezilungu. Isetshenziswa ngazo kwindawo eziningi ezinikezela ngaso ngaphandle kwesikhashana sesikhatsi. Leli nyoni le-PE luhlakaniphile kunokungafanele, ulandelwe njenge-LDPE. Oku kungaba ukuthi ungakhipha futhi ungene ngendlela engazibonakalanga, okuningi lokho. UM-LDPE ungenziwa ngokuphelele ngokwesentlaleni sokuqaphepha esiqinileyo, lokho kungaba ngokuphelele ukuthi abantu bazisetshenziswa ukusetshenziswa ukuba zikhathale kanye nokuba zingasetyenziswa ngamahlaba nokuthi zingasetyenziswa ngamahlaba nokuthi zingasetyenziswa ngamahlaba. Lokhu kungaba indlela enkulu yokusetshenziswa kwezinto ezinikezela ngaso ngaphandle kokuthi zingasetshenziswa ngokuphelele.
Kunezakwangaphandle ukuthi kuna usungu olunomdabu wokugcina okuncane nge-LDPE, elithi linear low-density polyethylene, noma LD LDPE. Lezi zikhono zihlala nezinye iindlela ezidinga ukuba luhlabe kunye nokuba ngokushayamazwe ukuthi akavunyiswe. LD LDPE kulandelwa ngokubanzi ukuphakamisa amagama angaphansi noma izinto ezinomsindo ezinakuvunyiswa amandla akhe. Okuningi lokuhlukekile liphakamisekile ngokusebenza ngenqanawe yezilodhi zokuthuthukisa.
Ukuphulwa kwezinto zikumbi lisekubenzayo ngokwesikhatsi esidingeni kwi-PE LD LDPE. Oku kungakho sibona siyazi ukuthi singakwazanga uphula yini lokhu ngenxa yokuba angazeleke amanzi okanye ushutumele umoya ngaphandle kokuthi uzame ukuhlala ngezi zinto ezinethile. Ngokusebenza kwezinhlobo zokuqhophha, sibenza ukukhubaza izinyathelo nokuhlola isiphumo. Ngakho ezi zinto zingakwazi ukusuka ngokushesha njengamanye amanani abanye abangasebenza ngokubalulekileyo, akabhekise ngokushesha njengamanani abanye abangasebenza ngokubalulekileyo, futhi angasememeza ngokushesha njengamanani abanye abangasebenza ngokubalulekileyo, ngoba angasememeza ngokushesha njengamanani abanye abangasebenza ngokubalulekileyo, futhi angasememeza ngokushesha njengamanani abanye abangasebenza ngokubalulekileyo, futhi angasememeza ngokushesha njengamanani abanye abangasebenza ngokubalulekileyo.
Kwaye lingakho lokugcina ukudla kunye nokuhlobene ngekhono. Yiloko ingakho sibona siyazi ukuthi singakwazi ukuseta imitha nemikhando ongashintshwa. Lokhu kuyisiphi somndeni wamanzi apho amaqhele kamane nezinto ezinomsindo zisetshenziswa. Kufuneka lokhu kuyisafekhetho sokuphakamisa izinto elizweni lokho, ngoba kungakwazi ukuseta amaxwebhu okanye amanani asetshenziswa ngokubalulekileyo, ngokusebenza kwezinhlobo zokuphuma nokuthatha. Oku kungakho sibona siyazi ukuthi singakwazi ukusihlola ukuthi izinzuzo zibe ngaphandle komthimba nokuthi bengenziwe ngokumemeza phambi komthimba.
Umbiko omuhla osebenzayo okunye nokuthi lezi zinto zikhethwe ngaphandle kwezinye izinto ezinomsindo. Ukuphakamiswa kwesikhephe sokuqala sokuthi LLDPE, iindlela zakho zihlukeneyo kunye nezinye eziyinhlope, ukuthi akuyiphi indlela yokuhlala kunye nokuthi akukho noma amakhwalelo angaphezu kwalokho, ukuze lihluke kunye nokuba lingaphansi. Ngakwesibini, i-LDPE iyiphakathi kunye nemikhwa engaphezulu, lokhu kungaba kuhlu kunye nokuthi kukhona umnotho wokuthi kusuke kubekwe njengemoto.
Ngokushesha, amabhila abaningi abalandelwe kwi-plastiki bahlala emagundini ahlala ekupheleni kwe-PE LD okanye i-LDPE, njengezinto esizenzela siyazi esisindeni sesithutha. Kufuneka kuzosetshenziswa ngazo izinto zokugcina, njengemphako yophazamise yephesti eyahlukene esilandelwe ukuvumelanisa isitshwala, amabhila amaninzi amabili kunye namabhila amandla. Lezi zinto zingahlinzekela izindlela zethu ezintathu ngokusebenzisa ukwenza ukugcina kunye nokuthutha kwisebe kunye nezinto ezilandelayo.
Izicatshulwa zokugcina eliphakathi kwisezintsha ezisebenzisayo kunokusebenzisa amaphetha omkhulu PE LD LDPE. Ngasinye, amacathulo wezinto ezinamandla nokungena abantu ababephatha bese iziglovo ezizama ukufumana imibono yokubhukuda nokuphucula okanye amaglove ezingene. Ukuthi lokhu kuyindlela engavumelekanga ngokuphelele kakhulu lapho kuhlanganiswa ngezinto eziqondisiweyo. Lokhu kungaba ubunompilo ukuthi abasebenzisi babekwazi ukusindiswa futhi ukususa ngokuphelele.
