Ngokuthuthuka kwezobuchwepheshe kanye nokudlondlobala kwemidlalo yangaphandle,amatafula okugoqa epulasitikikancane kancane ziye zabonakala emehlweni abantu.Izuze umusa kubantu ngevolumu yayo encane kakhulu, isisindo esilula kanye nokusetshenziswa kahle ngemva kokugoqa.Itafula eligoqayo lakhiwe iphaneli kanye nohlaka.Namuhla ngizokwethula impahla yetafula eligoqayo.
I-polyethylene ephezulu kakhulu (i-HDPE), impushana emhlophe noma umkhiqizo oyimbudumbudu.Okungenabuthi, akunambitheki, okucwebezelayo okungama-80% kuya ku-90%, indawo yokuthambisa engu-125 kuya ku-135°C, izinga lokushisa lesevisi lifika ku-100°C;
ubulukhuni, amandla aqinile kanye nokukhasa kungcono kune-polyethylene ephansi;
ukumelana nokugqoka, ugesi Ukufakwa kahle, ukuqina kanye nokumelana nokubanda;
ukuzinza okuhle kwamakhemikhali, okungancibiliki kunoma yiziphi izincibilikisi eziphilayo ekamelweni lokushisa, ukugqwala ukumelana nama-asidi, ama-alkali nosawoti ohlukahlukene;
ifilimu ine-permeability ephansi ku-vapor wamanzi nomoya, nokumuncwa kwamanzi Okuphansi;
ukumelana nokuguga okungalungile, ukumelana nokuqhekeka kwemvelo akukuhle njenge-polyethylene ephansi, ikakhulukazi i-oxidation eshisayo izokwehlisa ukusebenza kwayo,
ngakho-ke ama-antioxidant nama-absorber ultraviolet kumele kwengezwe ku-resin ukuthuthukisa lokhu kuntuleka.
Ifilimu ye-polyethylene ephezulu kakhulu inokushisa okuphansi kokushisa kokushisa ngaphansi kokucindezeleka, ngakho-ke kufanele kuqashelwe uma uyisebenzisa.
Kuleli khulu leminyaka, intuthuko yenguquko yenzeke emkhakheni wamapayipi, okungukuthi, "ukushintsha insimbi ngepulasitiki".Ngokuthuthuka okusheshayo kwesayensi yezinto ze-polymer nobuchwepheshe, ukujula kokuthuthukiswa nokusetshenziswa kwamapayipi epulasitiki, kanye nokuthuthukiswa okuqhubekayo kobuchwepheshe bokukhiqiza, amapayipi epulasitiki abonise ngokugcwele ukusebenza kwawo okuhle kakhulu.
Namuhla, amapayipi epulasitiki awasaphazami “njengezinto ezishibhile” zamapayipi ensimbi.Kule nguquko, amapayipi e-polyethylene athandwa futhi aya ngokuya ekhanya ngokugqamile.Zisetshenziswa kakhulu ekudluliselweni kwegesi, ukuhlinzekwa kwamanzi, ukuthuthwa kwendle, ukuchelela ngenkasa kwezolimo, ukuthutha okuqinile kwezinhlayiyana ezimayini, kanye nasezindaweni zikawoyela, amakhemikhali, iposi kanye nezokuxhumana, njll., ikakhulukazi emikhakheni esetshenziswa kabanzi ukuthuthwa kwegesi.
