Yini impahla ye-HDPE? Ukuhlaziywa okuphelele kwezimpawu kanye nokusetshenziswa kwe-polyethylene ephezulu
Embonini yamakhemikhali, i-HDPE iyinto ebaluleke kakhulu, igama layo eligcwele liyi-polyethylene ephezulu (i-polyethylene ephezulu) .Kuyini ngempela i-HDPE? Le ndatshana izokunikeza impendulo eningiliziwe kanye nokuhlaziywa okujulile kwezimpawu ze-HDPE, inqubo yayo yokukhiqiza nezinhlobo zayo ezahlukahlukene.
Imiqondo eyisisekelo nesakhiwo samakhemikhali se-HDPE
Yini i-HDPE? Ukusuka endaweni yamakhemikhali yokubuka, i-HDPE iyi-polymer ye-thermoplastic eyakhiwe nge-polymerication yokwengeza amamomoro we-ethylene. Isakhiwo saso samangqamuzana sibonakaliswa ngamaketanga amade we-polyethylene anesisindo esiphakeme samangqamuzana namaketanga ambalwa ahlanganisiwe phakathi kwawo, okuholela ekuhlelweni kwamanye ama-molecular. Lokhu kuhlelwa kwama-molecular okuqinile kunika i-HDPE ngobuningi obuphezulu emndenini we-polyethylene, ngokuvamile phakathi kuka-0.940 g / cm³ no-0.970 g / cm³.
Izakhiwo eziphakeme ezibonakalayo ze-HDPE
Izinto ze-HDPE zibonisa izakhiwo eziningi ezinhle kakhulu ezibonakalayo ngenxa yesakhiwo saso esiyingqayizivele se-molecular. Inamandla aphezulu nokuqina futhi ikwazi ukubekezelela izingcindezi eziphakeme zemishini, okwenza kube kuhle kakhulu kuzinhlelo zokusebenza ezithwala umthwalo.hdpe inokumelana okuhle kwamakhemikhali, okwenza kube lusizo ekugcineni kwamakhemikhali.
I-HDPE futhi inokumelana kahle kwezinga lokushisa okuphansi, ikwazi ukugcina ubulukhuni bayo ezindaweni eziphansi njenge-40 ° C ngaphandle kokuba brittle. Iphinde ibe nezakhiwo ezinhle zokufakwa kukagesi, okuholele ekusetshenzisweni kwayo ekufuneni izintambo nezintambo.
Inqubo yokukhiqiza ye-HDPE kanye nezindlela zokucubungula
Ngemuva kokuqonda ukuthi hlobo luni lwezincwadi ze-HDPE, ake sibheke inqubo yalo yokukhiqiza.hdpe kuvame ukukhiqizwa yinqubo ephansi ye-polymerisation, okungukuthi ngaphansi kwezimo eziphansi ze-polymerisation, nge-Ziegler-Natta Catalyst noma i-Phillips Catalyst njenge-catalyst enkulu, ngesigaba segesi, isixazululo noma izindlela ze-slurry polymerisation. Lezi zinqubo ziholela ku-HDPE nge-crystaltaltity ephansi namazinga aphezulu ama-crystallation, okuholele endabeni ephezulu ye-polyethylene.
Izinto ze-HDPE zinezinkulumo ezinhle futhi zingabunjwa ngezindlela ezahlukahlukene zokucubungula, njengokubumba kokujola, ukushaya kokubumba nokubumba kokubumba. Ngenxa yalokhu, i-HDPE ingenziwa ngezindlela eziningi zemikhiqizo efana namapayipi, amafilimu, amabhodlela kanye neziqukathi zepulasitiki.
Izindawo ezahlukahlukene zezicelo ze-HDPE
Ngenxa yezakhiwo eziningi ezinhle kakhulu zezinto ze-HDPE, zisetshenziswa kabanzi kwizimboni ezahlukahlukene. Embonini yokupakisha, i-HDPE isetshenziswa kakhulu ekwakheni izinhlobo ezahlukahlukene zamabhodlela epulasitiki, ama-botle cap, amafilimu okupakisha wokudla, njll. Ubuningi bayo obuphakeme kanye nokuqina okuphansi kuqinisekisa ukulondolozwa kwesikhathi eside kwephakheji. Embonini yezokwakha, i-HDPE isetshenziselwa ukukhiqiza ukulethwa kwamanzi kanye namapayipi amanzi namapayipi egesi, futhi ukugqwala kwawo kanye nokumelana kwayo kwenza kuthembeke ezindaweni ezinokhahlo.
Emkhakheni wezolimo, i-HDPE isetshenziselwa ukwenza amafilimu ezolimo, amanetha kanye neminye imikhiqizo, lapho ukumelana khona kwe-UV nokuqina kuqinisekisa ukuvikelwa kwezitshalo kanye nezithelo.hdpe kusetshenziswa kabanzi ekwakheni ukufakwa kwezintambo nezintambo, kanye naku Izinhlobo zamathangi neziqukathi ezivinjelwe ngamakhemikhali.
Ukugcina
I-HDPE iyi-polymer ebonakalayo enezakhiwo ezinhle kakhulu njengamandla aphezulu, ukumelana kwamakhemikhali, ukumelana kwamazinga okushisa okuphansi kanye nokusebenza okulula. Inezinhlobonhlobo zezicelo ngamakhemikhali, ezokwakha, ezolimo kanye nezinye izinkambu. Uma usacabanga ukuthi "Kuyini i-HDPE Material", ngethemba lokuthi ngalesi sihloko, unokuqonda okuphelele kwezimpawu nokusetshenziswa kwe-HDPE, ngokungangabazeki kungenye yezinto ezibalulekile eziyisisekelo embonini yesimanje.
