Iyini i-BPADA CAS 38103-06-9?

I-4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) (BPADA) iyi-monomer ye-polyetherimide elungisiwe kanye nohlobo lwe-polyimide e-fusible. I-4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) ayigcini nje ngokugcina zonke izakhiwo ezinhle ze-polyimide kodwa futhi inokusebenza kahle kokucubungula kwepulasitiki ejwayelekile yepulasitiki. Ngaphezu kwalokho, i-4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) inentengo ephansi futhi ifanelekela ukulungiswa kwemikhiqizo enezindonga ezincane kanye nemikhiqizo eyinkimbinkimbi ngokwesakhiwo.

Isicelo

1. Hlanganisa imikhiqizo ye-polyimide (PI) esebenza kahle kakhulu enenhloso ejwayelekile

Lolu uhlelo lokusebenza olujwayelekile noluyinhloko lwe-BPADA. I-BPADA i-polycondensed nama-diamine monomers avamile njenge-4,4' -diaminodiphenyl ether (ODA) ukwakha i-polyimide ehlanganisa "ukumelana nokushisa kanye nokucutshungulwa kalula". Lolu hlobo lwezinto ze-PI, ngenxa yokuba khona kwezibopho ze-ether namaqembu e-isopropyl esakhiweni salo sama-molecule, lugcina ukumelana nokushisa okuphezulu kwe-PI (izinga lokushisa lenkonzo yesikhathi eside elingu-180-220℃). I-BPADA kulula futhi ukwenziwa amafilimu, amapuleti, njll. kune-PI evamile, futhi ivame ukusetshenziswa ku:

1) Izingxenye eziyisisekelo zokuvikela ugesi emkhakheni we-elekthronikhi: Ifilimu eyisisekelo kanye nefilimu yesembozo yokwenza amabhodi wesekethe aphrintiwe aguquguqukayo (i-FPC), kanye ne-varnish yephepha/yokuvikela ugesi engashisi kakhulu yama-motor nama-transformer, ukuze kuhlangatshezwane nezidingo "zokumelana nokushisa okuncane + nokushisa" kwezingxenye ze-elekthronikhi, njengokuvikelwa kokuvikela ugesi kwangaphakathi kwama-electronics abathengi kanye nama-motor ezimboni.

2) Izingxenye ezivamile zezimboni ezimelana nokushisa okuphezulu: Zenziwe ngamapuleti namashubhu e-PI, zisetshenziselwa amabhulakhethi amelana nokushisa okuphezulu azungeze izinjini zezimoto kanye nezingxenye zangaphakathi ezimelana nokushisa kwezinto zasekhaya (ezifana nama-oven nama-oven e-microwave). Zingamelana nokushisa okungaphezu kuka-150℃ isikhathi eside, futhi zimelana nokuguga nokuqhekeka.

2. Shintsha ama-resin avamile ukuze uthuthukise ukusebenza

Ekuguqulweni kwe-resin okuvamile, i-BPADA, njenge-"monomer yokuqinisa engamelani nokushisa", ivame ukusetshenziswa ukwenza ngcono ukusebenza kwama-resin epoxy nama-resin e-phenolic nokwandisa izimo zokusetshenziswa kwawo:

1) Ukuguqulwa kwe-resin ye-Epoxy: Uma ihlanganiswa ne-resin evamile ye-epoxy, i-BPADA ithuthukisa ukumelana nokushisa okuphezulu kwe-resin (okwandisa ukumelana nokushisa kwesikhathi eside kwe-resin elungisiwe kusuka ku-120℃ kuya ngaphezu kuka-180℃), futhi isetshenziselwa ukubopha imishayo eyinhloko yama-wind turbine blades kanye nokugqoka okuvikelayo kwamakhebula ane-voltage ephezulu, okuhlangabezana nezidingo zokusetshenziswa kwesikhathi eside ezindaweni zangaphandle noma zezimboni.

2) Izinto zokusetshenziswa eziyisisekelo zokumboza/izinamathelisi ezimelana nokushisa okuphezulu: Njengengxenye yokuxhumanisa yokumboza kanye nezinamathelisi, i-BPADA ihlanganiswa nama-phenolic resins kanye nama-silicone resins ukukhiqiza ukumboza okumelana nokushisa okuphezulu kwemishini yezimboni (njengezinamathelisi ezimelana nokugqwala kanye nezinamathelisi ezimelana nokushisa kwezindonga zangaphakathi zama-boilers namapayipi), kanye nezinamathelisi ezimelana nokushisa okuphezulu eziphilisayo ekamelweni lokushisa kwezinsimbi kanye nezinto zobumba. Lezi zivame ukusetshenziselwa ukuvikela nokubopha imishini yemishini kanye neyamakhemikhali.
