Iyini impahla ye-PES? Ukuhlaziywa okujulile kwezakhiwo kanye nokusetshenziswa kwe-polyethersulfone
Emkhakheni wezinto zamakhemikhali, "iyini impahla ye-PES" umbuzo ovamile, i-PES (i-Polyethersulfone, i-Polyethersulfone) i-polymer ye-thermoplastic ephezulu yokusebenza, ngenxa yamandla ayo omshini omuhle kakhulu nokumelana nokushisa okuphezulu, okusetshenziselwa kabanzi emikhakheni eminingi yezimboni. Kulesi sihloko, sizoxoxa ngokuningiliziwe izakhiwo ezibonakalayo, izindlela zokulungiselela kanye nezindawo eziyinhloko zokusetshenziswa kwe-PES.
Izakhiwo eziyisisekelo ze-PES
I-PES i-amorphous thermoplastic material enokumelana nokushisa okuphezulu kanye nezakhiwo ezizinzile zemishini. Ukushisa kwayo kwe-glass transition (Tg) kuvame ukuzungeze i-220 ° C, okwenza kube nokuzinza ezindaweni zokushisa okuphezulu.I-PES inokumelana okuhle kakhulu ne-oxidation kanye ne-hydrolysis, futhi iyakwazi ukumelana nokuwohloka lapho kuvezwe ezindaweni ezinomswakama noma izinga lokushisa eliphezulu lamanzi isikhathi eside. Lezi zakhiwo zenza i-PES ibe ilungele ukwenziwa kwezingxenye ezizosetshenziswa ezindaweni ezidinga kakhulu.
Ukulungiswa Nokucubungula kwe-PES
I-PES ngokuvamile ilungiswa nge-polymerisation, ikakhulukazi ehlanganisa i-polycondensation ye-bisphenol A kanye ne-4,4′-dichlorodiphenylsulfone. Impahla inokucutshungulwa okuhle futhi ingacutshungulwa ngezindlela ezihlukahlukene, okuhlanganisa ukubunjwa komjovo, i-extrusion kanye ne-thermoforming.PES ingacutshungulwa emazingeni okushisa aphakathi kuka-300 ° C no-350 ° C, okudinga ukuthi umsebenzisi abe nemishini emihle yokucubungula kanye namasu okulawula. Nakuba i-PES inzima ukuyicubungula, imikhiqizo ivame ukuba nokuzinza okuhle kakhulu kwe-dimensional kanye nokuqedwa kwendawo.
Izindawo eziyinhloko zokufaka izicelo ze-PES
Impahla ye-PES isetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yokusebenza kwayo okuhle kakhulu. Embonini kagesi kanye ne-elekthronikhi, i-PES isetshenziswa kakhulu ukwenza ukufakwa kwezixhumi zikagesi nezixhumi ngenxa yokufakwa kwayo okuhle nokumelana nokushisa, futhi isetshenziswa kabanzi embonini yemishini yezokwelapha. Ngenxa yokumelana kwayo nezinga lokushisa eliphezulu, ukumelana ne-hydrolysis kanye nokumelana namakhemikhali, i-PES iyinto ekahle yokwakha imikhiqizo yezokwelapha efana nezinsimbi zokuhlinza, iziqukathi zokuvala inzalo nezihlungi.
I-PES Ekuhlanzeni Amanzi
Indawo yokufaka isicelo ephawulekayo iwukwelashwa kwamanzi.I-PES isetshenziswa kakhulu ekwenzeni ulwelwesi lokwelashwa kwamanzi ngenxa yokungangeni kwayo kwamakhemikhali okuhle kakhulu kanye nokumelana nokungcoliswa. Lawa malwelwesi ngokuvamile asetshenziswa ezinhlelweni ze-ultrafiltration kanye ne-microfiltration futhi ayakwazi ukususa ngempumelelo izinto eziqinile ezimisiwe nama-microorganisms emanzini kuyilapho egcina ukungena kahle kakhulu namandla okusebenza. Lolu hlelo lokusebenza luphinde lubonise ukubaluleka kwezinto ze-PES ezinhlelweni zokusebenza zokusebenza okuphezulu.
Izinzuzo Zemvelo ze-PES
Ezweni lanamuhla elikhathalela imvelo, izinto ezibonakalayo ze-PES nazo zisesikhanyeni: I-PES inempilo ende yesevisi nokuqina okuhle, okunciphisa imvamisa yokushintshwa kwezinto ezibonakalayo ngakho-ke ukumosha, futhi inqubo yokukhiqiza inobungani bemvelo, asikho isidingo sezincibilikisi, okuyinikeza inzuzo mayelana nokusimama.
Isiphetho
Kusukela ekuhlaziyweni okunemininingwane kuleli phepha, singaphetha ngokuthi i-PES iyimpahla esezingeni eliphezulu ye-thermoplastic enezakhiwo ezinhle kakhulu kanye nezinhlelo eziningi zokusebenza. Kungakhathaliseki ukuthi kusendimeni kagesi neye-elekthronikhi, izinsiza zezokwelapha noma ukwelashwa kwamanzi, i-PES ibonise izinzuzo eziyingqayizivele. Kubafundi abafuna ukwazi ukuthi “i-PES yenziwe ngani”, i-PES iyimpahla esemqoka enohlu olubanzi lwezinhlelo zokusebenza ezingaba khona neziningi, futhi izoqhubeka idlala indima ebalulekile ekuthuthukisweni kwezimboni esikhathini esizayo.
