Yini i-POE? Ukuhlaziywa okujulile kwezakhiwo nezindlela ezisetshenziswayo
I-POE (i-Polyolefin Elastomer) iyimpahla ye-polymer esetshenziswa kabanzi embonini yamakhemikhali eminyakeni yamuva nje. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokwanda kwesidingo sezimboni, i-POE ihamba phambili emikhakheni eminingi ngenxa yezakhiwo zayo eziyingqayizivele. Kulesi sihloko, sizoxoxa ngokuningiliziwe ukuthi iyini i-POE, futhi sihlaziye izakhiwo zayo, inqubo yokukhiqiza kanye nezindawo zokufaka isicelo ukuze sisize abafundi baqonde kangcono ukubaluleka kwalokhu kwaziswa.
Izakhiwo Eziyisisekelo ze-POE
Iyini impahla ye-POE? Ngokwesakhiwo samakhemikhali, i-POE iyi-elastomer eyenziwe nge-copolymerization ye-ethylene ene-copolymerising monomer, ngokuvamile i-α-olefin. Izakhiwo zayo ezibalulekile zihlanganisa ukunwebeka okuhle kakhulu, ukuminyana okuphansi, ukucaca okuphezulu, kanye nesimo sezulu esihle kanye nokumelana nezinga lokushisa eliphansi. Yilezi zakhiwo ezivumela i-POE ukuthi iphumelele ezinhlobonhlobo zezinhlelo zokusebenza, ikakhulukazi kwezezimoto, izinto zokupakisha kanye nokushefa kwekhebula.
Inqubo yokukhiqiza ye-POE
Ukuze uqonde ukuthi iyini i-POE, kubalulekile ukubheka inqubo ekhiqizwa ngayo, ngokuvamile eyenziwa yi-metallocene catalyst polymerisation. Ama-Metallocene catalysts ama-catalyst asebenza kakhulu avumela ukulawula okunembile kokusatshalaliswa kwesisindo se-molecule ye-polymer kanye nokushumeka kwama-copolymer monomers. Le nqubo iphumela ekuqhubekisekeni okuhle kakhulu kanye nezakhiwo zomkhiqizo ezingaguquki ezinhlobonhlobo zezindlela zokucubungula ezifana nomjovo, ukukhishwa kanye nokubunjwa kokushaywa.
Izindawo ezisetshenziswa kakhulu ze-POE
Uma usuyazi ukuthi i-POE iyini, ukuqonda izindawo zayo zokusetshenziswa kubalulekile ekuqondeni okugcwele kwezinto. Ngenxa yokunwebeka nokuqina kwayo, i-POE isetshenziswa ezinhlotsheni eziningi zezimoto, ikakhulukazi kuma-seal ezimoto, obhampa kanye nezinto zangaphakathi.Ukuminyana okuphansi kwe-POE nokuba sobala kwenza ilungele izinto zokupakisha zekhwalithi ephezulu, njengefilimu yokupakisha ukudla. Izinto zokushela ikhebula nazo ziyindawo ebalulekile yesicelo se-POE. Ngesimo sezulu esihle kanye nokumelana nezinga lokushisa eliphansi, i-POE inganweba ngempumelelo impilo yesevisi yezintambo.
I-POE iqhudelana namanye ama-elastomer
Ukuze siqonde kangcono ukuthi iyini i-POE, singayiqhathanisa namanye ama-elastomer avamile afana ne-TPU (i-thermoplastic polyurethane) ne-EPDM (i-ethylene propylene diene rubber), enobuningi obuphansi, ukucutshungulwa okuhle kakhulu kanye nezindleko eziphansi. Futhi uma kuqhathaniswa ne-EPDM, i-POE yenza kangcono ngokwezinga lokushisa eliphansi nokusebenza obala. Ngenxa yalokho, i-POE ivame ukusetshenziswa njengenye into yokuthuthukisa ukusebenza komkhiqizo nokunciphisa izindleko.
Isifinyezo
Yini i-POE? Kalula nje, i-POE iyimpahla ye-elastomeric esebenza kahle enezinhlobonhlobo zezinhlelo zokusebenza. Ngenxa yezakhiwo zayo eziyingqayizivele, njengokunwebeka okuphezulu, ukuminyana okuphansi kanye nokucutshungulwa okuhle kakhulu, i-POE ikhombisa amandla amakhulu ezindaweni eziningi. Kungakhathaliseki ukuthi kusembonini yezimoto, imboni yokupakisha, noma ukukhiqizwa kwamakhebula, i-POE ivula amathuba amasha kusayensi yezinto zokwakha nobunjiniyela.
Ngethemba, ngalesi sihloko, abafundi bazothola ukuqonda okucacile kokuthi iyini i-POE nokuthi kungani ithatha indawo ebaluleke kangaka embonini yamakhemikhali.
