I-3,3′,4,4′-Biphenyltetracarboxylic dianhydride (i-CAS 2420-87-3, efinyeziweyo njenge-BPDA) yi-monomer eyintloko yokwenza izinto ze-polymer ezisebenzayo kakhulu, kwaye ukusetyenziswa kwayo kugxile kakhulu kwintsimi yezinto eziphezulu.
1. 3,3′,4,4′-Biphenyltetracarboxylic dianhydride isetyenziswa njengezixhobo zesakhiwo ezimelana nobushushu obuphezulu kwizixhobo zeenqwelo-moya (ezifana nezixhobo zasekuhlaleni zeekhabhathi zesathelayithi) kunye neengubo zokwambathisa izixhobo zenjini; I-substrate ye-antenna eguquguqukayo yezixhobo kunye nomaleko wokwambathisa intambo omelana nobushushu obuphezulu.
2. I-BPDA ingasetyenziswa kwiisekethe ezidibeneyo (ics): ukulungiselela iifilimu zokukhusela ezidibanisa iileya, ukunciphisa ukuguquguquka okubangelwa kukufudumala kweetshiphusi, kunye nokuphucula uzinzo lweetshiphusi. Yenziwe ngezinto ze-PI ezidityanisiweyo (ezifana ne-carbon fiber kunye ne-graphite egcweleyo), ezisetyenziswa kwiibheringi kunye nezitywini phantsi kweemeko zokusebenza ezishushu kakhulu (ezifana nokuvala izinto zeenjini zeemoto kunye nezixhobo zeekhemikhali), ukutshintsha izinto zesinyithi ukunciphisa ukuguguleka kunye nokubola.
3. Ngaphandle kwe-polyimide, i-BPDA isenokusabela kunye nee-monomers ezahlukeneyo ukwenza ezinye izinto ze-polymer ezisebenzayo, yandisa imida yayo yokusetyenziswa
I-polyamideimide yokwenziwa (PAI) : I-BPDA iphendula kunye ne-diisocyanate ukuze yenze i-PAI. Olu hlobo lwezinto ludibanisa ukumelana nobushushu obuphezulu be-PI kunye nokuxhathisa kwempembelelo kwe-polyamide, kwaye ingasetyenziselwa ukulungiselela iindawo zeplastiki zobunjineli eziphezulu.
I-polyetherimide eyenziweyo (i-PEI): Isabela kwiidiamines ezineebhondi ze-ether ukuze zenze i-PEI. Ukusebenziseka kwayo kungaphezulu kunokwe-PI yendabuko. Ingenziwa ibe ziigobolondo zezixhobo ze-elektroniki kunye nezihlanganisi ezimelana nobushushu obuphezulu ngokubumba inaliti, kuthathelwa ingqalelo amandla kunye nokusebenziseka lula.
4. Amaqela e-anhydride kwimolekyuli ye-BPDA anokungenelwa ziimpendulo zokuvula i-ring kunye namaqela e-epoxy e-epoxy resin kwaye asetyenziswe njengee-agents zokuphilisa ezimelana nobushushu obuphezulu:
I-4,4′-Biphthalic Anhydride 2420-87-3 isetyenziswa kakhulu ekulungiseleleni "izinto ezidityanisiweyo ze-epoxy ezimelana nobushushu obuphezulu", ezifana nokucocwa kweengcambu zeebhleyidi zomoya (ezifuna ukumelana nokuguga okungaphezulu kwexesha elide ngaphandle) kunye nokucocwa kwe-epoxy substrates kwiibhodi zesekethe eziphezulu, ukuphucula uzinzo lobushushu (i-Tg yezinto ezicociweyo inokwandiswa ibe ngaphezulu kwe-180℃) kunye namandla oomatshini ezinto ze-epoxy.
Ihlala ipakishwe kwi-25kg/drum, kwaye inokwenziwa ngokwezifiso.
