Isishwankathelo, akukho nzima ukubona isizathu sokuba i-Pollimidide ingavela kwi-60s kunye nama-70s, uninzi lwee-polyscys ze-heterocycclic zivele, * Ekugqibeleni yaba ludidi olubalulekileyo lwezixhobo zepolymer.
Indima ye-Polylimide i-PeAget
I-Polyomide yeGasket yi-gasket esebenzayo yeplastiki eyenziwe ngezinto ze-pollilomide. Le gasket idlala indima ebalulekileyo kwimveliso yezamashishini, ikakhulu iboniswa kule miba ilandelayo:
Okokuqala, indima yokutywina
Iirhasi ze-Polymidide zihlala zisetyenziswa njengezinto zokutywina ngenxa yokuqina kwabo kunye nokunganyangeki. Kwiplanga, i-valves, iimpompo kunye nolunye unxibelelwano lwezixhobo, ukusetyenziswa kweegesi zepolimide kunokuthintela ngokufanelekileyo igesi okanye ukuvuza okungamanzi, ukuqinisekisa ukusebenza kwesiqhelo kwenkqubo.
Okwesibini, indima yokuzala
Ngenxa yezinto ezibalaseleyo zombane ze-polylimide, ke i-polyamide yerhasi zihlala zisetyenziswa njengokuphazamiseka izixhobo zombane. Inokuhlula ngokuqhelekileyo isiphaluka, thintela ukuvuza okwangoku okanye isekethe emfutshane, ngenxa yoko ukuphucula ukhuseleko kunye nokuzinza kwezixhobo zombane.
Isiphumo sesithathu, isiphumo
Kwizixhobo zoomatshini, amalungu amaninzi okusebenza aya kuvelisa inkohliso kunye nefuthe. I-Polytotide ye-posket ngenxa yokuqina kwayo elungileyo kwaye inxibe ukunganyangeki, inokudlala i-buffer phakathi kwala macandelo, ukunciphisa ukunxiba kunye nengxolo, kwandise ubomi benkonzo yezixhobo.
Isine, ukuxhaphaza kwamachiza emichiza
Izinto zePolymide zinokuchasana ngokugqwesileyo, zinokuxhathisa ii-acids ezahlukeneyo, ialkalis, izinyibilikisi zezinto eziphilayo. Ke ngoko, kumashishini ekhemikhali kunye namayeza e-chikile, i-polyamidide irhasi isetyenziswa ngokubanzi kwimibhobho eyahlukeneyo, ii-reactors kunye nezinye izixhobo zokutywina kunye nokufakwa.
Kwisishwankathelo, i-polylimide yerhasi idlala indima enkulu kwimveliso yemizi mveliso. Ukuchasana nobushushu obuphezulu, ukumelana nobushushu obuphezulu, ukuxhaphaza, ukunxiba ukunganyangeki kunye nezinto eziphilayo ezifanelekileyo kunye nepropathi yombane, zenza ukuba ibe yinxalenye engenakuphikwa koomatshini kunye nezixhobo. Nokuba kukutywina, ukufuya, ukuntywila okanye ukungavisisani kwemichiza, i-polyamide ibonakalise ukusebenza kakuhle.
