Yini i-PE?
I-POLYETYLELE (Polyethylene), ingenye yezinto zokwakha zepulasitiki ezisetshenziswa kakhulu emhlabeni. Ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba nezamakhemikhali, izinto ze-PE zisetshenziswa ezinhlobonhlobo zezimboni. Ukusuka ezikhwameni zokupakisha kuya ezintweni zokwakha amapayipi, i-polyethylene cishe yonke indawo. Kulesi sihloko, sizohlola ngokuningiliziwe ukuthi iyini i-PE, izinhlobo zayo, izakhiwo nezindawo zohlelo lokusebenza.
1. Isakhiwo samakhemikhali kanye nokuhlukaniswa kwe-PE
I-PERMOPLAYS Resin eyakhiwe kusuka kuma-ethylene monomers ngokusebenzisa ukusabela kwe-polymerisation. Kuya ngengcindezi kanye nezimo zokushisa ngesikhathi senqubo ye-polymerication, izinto ze-PE zingahlukaniswa ezinhlotsheni eziningana:
I-Low Density PolyethLene (LDPE): Lolu hlobo lwezinto ezibonakalayo pen luhlelwe ngokukhululekile phakathi kwamaketanga amamolekliya futhi linokuguquguquka okuphansi.Lldpe linokuguquguquka okuhle kwamafilimu epulasitiki, izinto zokupakisha kanye namafilimu ezolimo .

I-Polity Density Polyethylene (HDPE): Amaketanga ama-molelisar ahlelwe ngokuqinile futhi abe nobunzima obuphakeme, ngakho-ke kukhombisa amandla angcono kanye nokumelana kwamakhemikhali.hdpe kuvame ukusetshenziswa ekwenziweni kwamapayipi, amabhodlela kanye neziqukathi zepulasitiki.

I-Linear Low density polyethylene (LLDPE): I-LLDPE iyi-polyethylene ephansi enezimpawu zamangqamuzana aqondile ahlanganisa ukuguquguquka kwe-LDPE ngamandla we-HDPE. Kuvame ukusetshenziswa ukwenza ifilimu elula, izikhwama zepulasitiki nezinto zokufaka izimboni.

2. Izici eziyinhloko zezinto zokwenziwa pe
Izinto ezibonakalayo zinezici eziningi eziphawuleka ngokomzimba nangamakhemikhali ngenxa yesakhiwo sayo esiyingqayizivele samangqamuzana, okwenza ukuthi kudlule ku-Excel ezinhlobonhlobo zezicelo:
Ukumelana kwamakhemikhali: Izinto ze-PE zinokumelana kahle nama-acids amaningi, i-alkali, usawoti kanye nezinsolo zokushisa zasekamelweni, okwenza kube fanele izimboni zamakhemikhali nezemithi.

Ukumelana nomthelela omuhle kanye namandla ashubile: I-HDPE, ikakhulukazi, inamandla aphezulu nokuqina futhi ikwazi ukubekezelela ukucindezelwa okuphezulu, okwenza kuvame ukusetshenziswa imikhiqizo edinga ukumelana nemithwalo.

Izakhiwo ezinhle kakhulu zokufaka okufakwayo: I-Pe Material i-insulator enhle kakhulu kagesi, eyenza isetshenziswe kabanzi njengesendlalelo sokufaka izintambo nezintambo.

Ukutholwa kwamanzi okuphansi: Izinto ze-PE zinomunyu ophansi kakhulu wamanzi ngakho-ke zigcina izakhiwo zayo ezibonakalayo ezindaweni ezinomswakama.

3. Izindawo zezicelo zezinto zokwakha
Ngenxa yezakhiwo zazo ezinhle nezinto ezinhle kakhulu, izinto ze-PE zidlala indima ebalulekile empilweni yansuku zonke nasemboni. Ukwazi ukuthi i-Pe isisiza ukuthi siqonde kangcono ububanzi bawo obubanzi bezicelo emikhakheni ehlukene:
Imboni yokupakisha: izinto ze-PE zisetshenziswa kabanzi ekwakheni amafilimu epulasitiki, izikhwama zezolimo zokudla kanye namafilimu ezolimo.Lldpe kanye ne-LLDPE zilungele izinto ezahlukene zokufaka eziguquguqukayo ngenxa yokuguquguquka kwazo okuhle kakhulu ngenxa yokuguquguquka kwawo okuhle kakhulu.

Imboni yokwakha kanye nepayipi: I-HDPE imvamisa isetshenziswa ekukhiqizweni kwamapayipi amanzi, amapayipi egesi namapayipi amakhemikhali ngenxa yokuphikiswa kwayo okuhle nokugqwala.

Imikhiqizo yasendlini: Imikhiqizo yepulasitiki eminingi yansuku zonke, efana namabhakede, izikhwama zemfucumfucu kanye neziqukathi zokugcina ukudla, zenziwa nge-polyethylene.

I-4. Ukuvikelwa Kwezemvelo kanye nokuphinda usebenzise kabusha kwezinto zokwakha
Naphezu kwezinzuzo zayo eziningi, ukusetshenziswa kwezinto ezisakazekile ezibanzi kuletha izinkinga zemvelo. Ngoba ayilimazi kalula, imikhiqizo ye-PE elahliweyo ingahle ibe nemithelela emibi yesikhathi eside kwi-ecosystem. Izinto ze-polyethylene zitholakala kabusha. Ngezindlela ezingokomzimba noma zamakhemikhali, imikhiqizo elahlekile ye-PE ingaphindiselwa ngezinto ezintsha, ngaleyo ndlela yehlisa umthelela emvelweni.
Ukugcina
Ngokuhlaziywa okungenhla, sinokuqonda okuningiliziwe kwendaba ethi "Kuyini Into Yezimali". Njengezinto ezibaluleke kakhulu zepulasitiki, i-polyethylene isetshenziswa kabanzi emikhakheni ehlukahlukene ngenxa yesakhiwo sayo esiyingqayizivele nezakhiwo ezinhle kakhulu. Yize ukusetshenziswa kwayo kubeka izinselelo zemvelo, ukuphathwa okuqhubekayo kwezinto zokwenziwa kwe-PE kungatholakala ngokuvuselelwa kabusha okunengqondo.
