Hlobo luni lwepulasitiki? Ukuchazwa okuningiliziwe kwezinhlobo, izakhiwo kanye nokusetshenziswa kwe-polyethylene (pe)
Yini ipulasitiki ye-PE?
"Yini i-PE PLOCT?" Lo mbuzo uvame ukubuzwa, ikakhulukazi kwizimboni zamakhemikhali nezokukhiqiza.pe, noma i-polyethylene, i-thermoplastic eyenziwe yi-polymering ethylene momer. Njengenye yepulasitiki evame kakhulu, i-PE yaziwa ngokusetshenziswa kwayo okuhlukahlukene nezinhlobonhlobo zezicelo. Izindleko zayo eziphansi, ipulasitiki ephezulu kanye nokuqina kwamakhemikhali kwenza kube yinto ebaluleke kakhulu embonini yanamuhla.
Izinhlobo zamapulasitiki we-PE
I-Pelyethylene (PE) ihlukaniswe izigaba ezintathu eziphambili: I-Low-density polyethylene (LDPE), i-polyethylene ephezulu (HDPE) kanye ne-linear low-density polyethyne (LLDPE).
I-Low Density PolyethLene (LDPE)
I-LDPE iyi-polyethylene enesakhiwo esihlakazekile, okuholela ekubuseni okuphansi. Kuyavumelana nezimo futhi kusobala futhi kuvame ukusetshenziswa ekwenziweni kwezikhwama zepulasitiki, zibambe amafilimu nezinto zokupakisha eziguqukayo.

I-Polyethylene ephezulu (HDPE)
I-HDPE inesakhiwo esithambile se-molecular kune-LDPE, okuholela ekujuleni okukhulu nokushisa okukhulu kanye nokumelana nomthelela.hdpe kuvame ukusetshenziswa ekukhiqizweni kwemikhiqizo yepulasitiki eqinile esetshenziswa empilweni yansuku zonke, njengamabhodlela obisi.

I-Linear Low Density PolyethLene (LLDPE)
I-LLDPE ihlanganisa ukuguquguquka kwe-LDPE namandla e-HDPE ngokunwebeka okuhle nokuvimba izinyembezi. Imvamisa isetshenziselwa ukwenza amafilimu aqinile, anjengamafilimu okufaka izimboni namazimboni.

Izakhiwo zepulasitiki PE
Ukuqonda "Yikuphi ipulasitiki etholakala pe" kudinga ukubhekisisa okujulile kwezakhiwo zayo ezibonakalayo. I-PolyethYlene inezimpawu ezilandelanayo ezilandelayo:
Ukuqina okuhle kwamakhemikhali
I-PolyethYlene inokumelana kahle namakhemikhali amaningi afana nama-acid, alkalis nosawoti. Ngalesi sizathu, izinto ze-PE zivame ukusetshenziswa ezitsheni zamakhemikhali namapayipi.

Ukumelana nomthelela omkhulu
Kokubili i-polyethylene ephezulu futhi ephansi-density inokumelana nomthelela omkhulu, okubenza bahle kakhulu ngokupakishwa nokugcinwa.

Ukufakwa kukagesi
I-Polyethylene ingumthakisi we-insulator omuhle kakhulu kagesi futhi ivame ukusetshenziswa embozweni wangaphandle wezintambo nezintambo zokuqinisekisa ukusebenza okuphephile kwemishini kagesi.

Izicelo zeplastikhi ye-PE
Uhla olubanzi lwezicelo ze-polyethylene uphendula ngokugcwele umbuzo othi "Yini i-PE? Ngenxa yezakhiwo zayo ezahlukahlukene, izinto ze-PE zihlala esikhundleni esibalulekile ezimbonini eziningi.
Ukuwowapha
I-PolyethYnene idlala indima ebalulekile embonini yefakiphakeli, ikakhulukazi endaweni yokufaka okuguqukayo, lapho izikhwama zepulasitiki namafilimu asetshenziswa kakhulu e-PE empilweni yansuku zonke.

Ukwakha & Amapayipi
I-polyethylene ephezulu (HDPE) isetshenziswa kabanzi embonini yezokwakha amapayipi, ukuhanjiswa kwamanzi kanye namapayipi okuhambisa igesi ngenxa yokugqwala kwawo kanye nokucindezela kwezakhiwo zokumelana nezakhiwo.

Izimpahla zabathengi nezasendlini
Amapulasitiki we-PE asetshenziswa nemikhiqizo yabathengi yansuku zonke efana namathoyizi, izimpahla zasendlini neziqukathi zokugcina. Le mikhiqizo ayiphephile nje kuphela futhi ingeyona enobuthi, kepha futhi ingavuselelwa ukuze inciphise ukungcoliswa kwemvelo.

Ukugcina
Ukufingqa, impendulo yombuzo othi "Yiliphi ipulasitiki le-PE?" Impendulo yalo mbuzo ihlanganisa ukwehlukahluka kwezinto ze-polyethylene kanye nezinhlobo zazo ezahlukahlukene. Njengezinto eziqinile zepulasitiki eziqinile, ezingabizi futhi ezibiza kancane, i-PE idlala indima ebalulekile kuzo zonke izici zomphakathi wanamuhla. Ukuqonda izinhlobo zayo ezahlukene nezakhiwo kungasisiza ukuba sisebenzise kahle lokhu okuqukethwe ukuthuthukisa imboni kanye nezinga lokuphila.
