Yintoni i-BPADA CAS 38103-06-9?

I-4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) (BPADA) yi-polyetherimide monomer elungisiweyo kunye nohlobo lwe-polyimide efusible. I-4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) ayigcini nje ngokugcina zonke iipropati ezintle ze-polyimide kodwa ikwanokusebenza kakuhle kweplastiki yeplastiki ngokubanzi. Ngaphezu koko, i-4,4'-(4,4'-ISOPROPYLIDENEDIPHENOXY)BIS(PHTHALIC ANHYDRIDE) inexabiso eliphantsi kwaye ifanelekile ekulungiseleleni iimveliso ezixineneyo kunye neemveliso ezintsonkothileyo ngokwesakhiwo.

Isicelo

1. Yenza iimveliso ze-polyimide (PI) ezisebenza kakuhle ezijolise ekusetyenzisweni ngokubanzi

Le yeyona ndlela iqhelekileyo neyintloko yokusebenzisa i-BPADA. I-BPADA i-polycondensed kunye ne-diamine monomers eziqhelekileyo ezifana ne-4,4' -diaminodiphenyl ether (ODA) ukwenza i-polyimide edibanisa "ukumelana nobushushu kunye nokulula kokusetyenzwa". Olu hlobo lwezinto ze-PI, ngenxa yokubakho kweebhondi ze-ether kunye namaqela e-isopropyl kwisakhiwo sayo se-molecular, igcina ukumelana nobushushu obuphezulu be-PI (ubushushu benkonzo yexesha elide obuyi-180-220℃). I-BPADA ikwalula ukwenziwa kwiifilimu, iipleyiti, njl.njl. kune-PI eqhelekileyo, kwaye isetyenziswa rhoqo kwi:

1) Izinto ezisisiseko zokukhusela ubushushu kwicandelo le-elektroniki: Ifilimu esisiseko kunye nefilimu yokugquma yokwenza iibhodi zesekethe eziprintiweyo eziguquguqukayo (i-FPC), kunye ne-varnish yephepha/yokukhusela ubushushu enganyangekiyo kumaqondo obushushu aphezulu kwiimoto kunye neetransformer, ukuhlangabezana neemfuno "zokunciphisa ubushushu + ukumelana nobushushu" zezinto ze-elektroniki, ezifana nokukhuselwa kokukhusela ubushushu bangaphakathi kwii-elektroniki zabathengi kunye neemoto zoshishino.

2) Izinto eziqhelekileyo ezimelana nobushushu obuphezulu kwimizi-mveliso: Zenziwe ngeepleyiti ze-PI kunye neetyhubhu, zisetyenziselwa iibrakethi ezimelana nobushushu obuphezulu ezijikeleze iinjini zeemoto kunye neendawo zangaphakathi ezimelana nobushushu kwizixhobo zasekhaya (ezifana nee-ovens kunye nee-ovens ze-microwave). Zinokumelana nobushushu obungaphezulu kwe-150℃ ixesha elide, kwaye ziyamelana nokuguga nokuqhekeka.

2. Guqula iiresini zesiqhelo ukuphucula ukusebenza

Kwinguqulelo ye-resin eqhelekileyo, i-BPADA, njenge-"monomer yokuqinisa engatshisi ubushushu", isetyenziswa kakhulu ukuphucula ukusebenza kwee-resin ze-epoxy kunye nee-resin ze-phenolic kunye nokwandisa iimeko zokusetyenziswa kwazo:

1) Ukuguqulwa kwe-epoxy resin: Xa idityaniswe ne-common epoxy resin, i-BPADA yonyusa ukumelana nobushushu obuphezulu be-resin (inyusa ukumelana nobushushu obude be-resin ecociweyo ukusuka kwi-120℃ ukuya ngaphezulu kwe-180℃), kwaye isetyenziselwa ukubopha imiqadi ephambili yeeblade ze-wind turbine kunye nokwambathisa ubushushu kwiintambo ze-high-voltage, ukuhlangabezana neemfuno zokusetyenziswa kwexesha elide kwiindawo zangaphandle okanye zoshishino.

2) Izinto ezisisiseko zokwenza izinto zokugquma/zokuncamathelisa ezimelana nobushushu obuphezulu: Njengenxalenye edibanisa izinto zokugquma kunye nezincamathelisi, i-BPADA idityaniswe nee-phenolic resins kunye nee-silicone resins ukuvelisa izinto zokugquma ezimelana nobushushu obuphezulu kwizixhobo zoshishino (ezifana nezinto zokugquma kunye nezimelana nobushushu kwiindonga zangaphakathi zeebhoyila kunye neepayipi), kunye nezinto zokugquma ezimelana nobushushu obuphezulu eziphilisayo kubushushu begumbi kwiintsimbi kunye neeseramikhi. Ezi zisetyenziswa rhoqo ukukhusela kunye nokubopha izixhobo zoomatshini kunye neekhemikhali.
