Yintoni imathiriyeli yePES? Uhlalutyo olunzulu lweempawu kunye nokusetyenziswa kwe-polyethersulfone
Kwintsimi yezinto zekhemikhali, "yiyiphi into ye-PES" ngumbuzo oqhelekileyo, i-PES (i-Polyethersulfone, i-Polyethersulfone) i-polymer ye-thermoplastic ephezulu, ngenxa yamandla ayo omatshini kunye nokumelana nokushisa okuphezulu, esetyenziswa ngokubanzi kwiindawo ezininzi zoshishino. Kule nqaku, siza kuxubusha ngokubanzi iimpawu eziphathekayo, iindlela zokulungiselela kunye neendawo eziphambili zesicelo se-PES.
Iimpawu eziphambili zePES
I-PES yimpahla ye-amorphous thermoplastic enokumelana nokushisa okuphezulu kunye neempawu ezizinzileyo zomatshini. Iqondo lokushisa lokutshintsha kweglasi (Tg) lihlala lijikeleze i-220 ° C, elenza lizinze kwiindawo eziphakamileyo zokushisa.I-PES inokumelana ne-oxidation kunye ne-hydrolysis, kwaye iyakwazi ukuxhathisa ukuthotywa xa ibonakaliswe kwiindawo ezinomswakama okanye ukushisa kwamanzi aphezulu ixesha elide. Ezi zakhiwo zenza ukuba i-PES ilungele ukwenziwa kwamalungu ukuze asetyenziswe kwiindawo ezifuna amandla.
Ukulungiswa kunye nokuLungiswa kwe-PES
I-PES idla ngokulungiswa ngepolymerisation, ikakhulu ibandakanya i-polycondensation ye-bisphenol A kunye ne-4,4′-dichlorodiphenylsulfone. Izinto eziphathekayo zinokucutshungulwa kakuhle kwaye zinokucutshungulwa ngeendlela ezahlukeneyo, kubandakanywa ukubunjwa kwe-injection, i-extrusion kunye ne-thermoforming.PES inokucutshungulwa kumaqondo okushisa phakathi kwe-300 ° C kunye ne-350 ° C, efuna ukuba umsebenzisi abe nezixhobo zokusebenza ezifanelekileyo kunye nobuchule bokulawula. Nangona i-PES inzima ukuyiqhuba, iimveliso zikholisa ukuba nozinzo olubalaseleyo lwe-dimensional kunye nokugqiba komphezulu.
Iindawo ezingundoqo zezicelo ze-PES
Izinto ze-PES zisetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokusebenza kwayo kakuhle. Kumashishini ombane kunye ne-electronics, i-PES isetyenziswa ngokubanzi ukwenza ukugquma kombane kunye nezihlanganisi ngenxa yokugquma kwayo okulungileyo kunye nokumelana nobushushu, kwaye isetyenziswa ngokubanzi kushishino lwezixhobo zonyango. Ngenxa yokumelana nobushushu obuphezulu, ukuxhathisa kwe-hydrolysis kunye nokumelana neekhemikhali, i-PES yinto efanelekileyo yokwenza iimveliso zonyango ezifana nezixhobo zotyando, izitya zokuvala inzala kunye nezihluzi.
I-PES kuNyango lwaManzi
Indawo yesicelo ephawulekayo yonyango lwamanzi.PES isetyenziswa ngokubanzi ekwenzeni i-membrane yokucoca amanzi ngenxa yokungasebenzi kakuhle kweekhemikhali kunye nokuchasana nokungcoliswa. Ezi membrane ziqhele ukusetyenziswa kwiinkqubo ze-ultrafiltration kunye ne-microfiltration kwaye ziyakwazi ukususa ngokufanelekileyo izinto eziqinileyo kunye ne-microorganisms ezimisiweyo emanzini ngelixa zigcina ukugqithiswa okugqwesileyo kunye namandla omatshini. Esi sicelo sibonisa ngakumbi ukubaluleka kwezinto ze-PES kwizicelo zokusebenza eziphezulu.
Izinto ezilungileyo zokusingqongileyo zePES
Kwihlabathi lanamhlanje elikhathalela indalo, iipropathi zezinto zePES nazo zikwindawo yokujonga: I-PES inobomi obude benkonzo kunye nokuqina okuhle, okunciphisa ukuphindaphindeka kokutshintshwa kwezinto kwaye ngenxa yoko ilahleko, kwaye inkqubo yemveliso ihambelana nokusingqongileyo, akukho mfuneko yamachiza okunyibilikisa, nto leyo enika inzuzo ngokwemiqathango yokuzinza.
Ukuqukumbela
Ukusuka kuhlalutyo olucacileyo kweli phepha, sinokugqiba ukuba i-PES yinto ephezulu yokusebenza kwe-thermoplastic eneempawu ezintle kunye noluhlu olubanzi lwezicelo. Nokuba ikwintsimi yombane kunye ne-elektroniki, izixhobo zonyango okanye unyango lwamanzi, i-PES ibonise iingenelo ezizodwa. Kubafundi abafuna ukwazi "yintoni i-PES eyenziwe ngayo", i-PES yinto ebalulekileyo enoluhlu olubanzi lwezinto ezinokwenzeka kunye nezicelo ezininzi, kwaye ziya kuqhubeka zidlala indima ebalulekileyo kuphuhliso lwezoshishino lwexesha elizayo.
