Uhlobo luni lwepulasitiki i-PE? Incazelo enemininingwane yezinhlobo, izakhiwo kanye nokusetshenziswa kwe-polyethylene (PE)
Iyini ipulasitiki ye-PE?
"Iyini ipulasitiki ye-PE?" Lo mbuzo uvame ukubuzwa, ikakhulukazi ezimbonini zamakhemikhali nezokukhiqiza.I-PE, noma i-polyethylene, i-thermoplastic eyenziwe nge-polymerising ethylene monomer. Njengenye yamapulasitiki ajwayelekile, i-PE yaziwa ngokusetshenziswa kwayo okuhlukahlukene kanye nezinhlelo eziningi zokusebenza. Izindleko zayo eziphansi, ipulasitiki ephezulu kanye nokuzinza kwamakhemikhali kuyenza ibe yinto ebaluleke kakhulu embonini yesimanje.
Izinhlobo ze-PE Plastics
Amapulasitiki e-polyethylene (PE) ahlukaniswe ngezigaba ezintathu eziyinhloko: i-polyethylene ephansi (LDPE), i-polyethylene ephezulu (i-HDPE) kanye ne-linear low-density polyethylene (LLDPE).
I-Low Density Polyethylene (LDPE)
I-LDPE iyi-polyethylene enesakhiwo esihlakazekile, okuholela ekukhuleni okuphansi. Iyaguquguquka futhi isobala futhi ivame ukusetshenziswa ekwenzeni izikhwama zepulasitiki, ifilimu yokudla kanye nezinto zokupakisha eziguquguqukayo.

I-High Density Polyethylene (HDPE)
I-HDPE inesakhiwo samangqamuzana esiqinile kune-LDPE, okuholela ekumineni okuphezulu nokushisa okukhulu nomthelela wokumelana nomthelela.I-HDPE ivame ukusetshenziswa ekukhiqizeni imikhiqizo yepulasitiki eqinile esetshenziswa ekuphileni kwansuku zonke, njengamabhodlela obisi, amapayipi namathoyizi.

I-Linear Low Density Polyethylene (LLDPE)
I-LLDPE ihlanganisa ukuguquguquka kwe-LDPE namandla e-HDPE ngokunwebeka okuhle nokumelana nokukhala. Ivamise ukusetshenziselwa ukwenza amafilimu aqinile, njengamafilimu okupakisha ezolimo nawezimboni.

Izakhiwo ze-PE plastic
Ukuqonda ukuthi "iyini ipulasitiki i-PE" kudinga ukubheka ngokujulile izakhiwo zayo ezibonakalayo. I-polyethylene inezici ezilandelayo zokuhlukanisa:
Ukuzinza kwamakhemikhali okuhle kakhulu
I-polyethylene inokumelana okuhle namakhemikhali amaningi anjengama-asidi, ama-alkali nosawoti. Ngalesi sizathu, izinto ze-PE zivame ukusetshenziswa ezitsheni zamakhemikhali namapayipi.

Ukumelana nomthelela ophezulu
Kokubili i-polyethylene ephezulu nephansi inokumelana nomthelela omkhulu, okuyenza ibe yinhle kakhulu ekupakishweni nasekugcinweni kwayo.

Ukufakwa kukagesi
I-polyethylene iyisivikeli esihle kakhulu sikagesi futhi ivame ukusetshenziswa embozweni yangaphandle yezintambo nezintambo ukuze kuqinisekiswe ukusebenza okuphephile kwezinto zikagesi.

Izicelo zamapulasitiki e-PE
Uhlu olubanzi lwezicelo ze-polyethylene luphendula ngokugcwele umbuzo othi "Iyini i-PE? Ngenxa yezakhiwo zayo ezihlukahlukene, izinto ze-PE zithatha isikhundla esibalulekile ezimbonini eziningi.
Ukupakisha
I-polyethylene idlala indima ebalulekile embonini yokupakisha, ikakhulukazi endaweni yokupakisha okuguquguqukayo, lapho izikhwama zepulasitiki ze-PE namafilimu kuyizicelo ezivame kakhulu ze-PE ekuphileni kwansuku zonke.

Ezokwakha & Piping
I-high density polyethylene (HDPE) isetshenziswa kabanzi embonini yokwakha ngamapayipi, amanzi kanye namapayipi okudlulisa igesi ngenxa yokugqwala kanye nezakhiwo zayo zokumelana nokucindezelwa.

Izimpahla Zabathengi Nezasekhaya
Amapulasitiki e-PE nawo asetshenziswa emikhiqizweni yansuku zonke yabathengi njengamathoyizi, impahla yasendlini kanye neziqukathi zokugcina. Le mikhiqizo ayiphephile kuphela futhi ayinabo ubuthi, kodwa ingaphinda igaywe kabusha ukuze kuncishiswe ukungcoliswa kwemvelo.

Isiphetho
Ukufingqa, impendulo yombuzo othi "Iyini ipulasitiki ye-PE?" Impendulo yalo mbuzo ihlanganisa ukuhlukahluka kwezinto ze-polyethylene kanye nohlu olubanzi lwezicelo. Njengempahla yepulasitiki ezinzile, ethambile futhi engabizi kakhulu, i-PE idlala indima ebalulekile kuzo zonke izici zomphakathi wanamuhla. Ukuqonda izinhlobo zayo ezihlukene kanye nezakhiwo kungasisiza ukuthi sikusebenzise kangcono lokhu okuqukethwe ukuthuthukisa imboni nezinga lokuphila.
