Siyazi ukuthi siyachuma kuphela uma singaqinisekisa kalula ukuncintisana kwethu kwamanani ahlanganisiwe kanye nenzuzo enhle ngesikhathi esifanayo kuMenzi we-OEM 3, 3′, 4, 4′-Biphenyltetracarboxylic Dianhydride/Bpda CAS 2420-87-3 we-Organic Synthesis, Samukela amakhasimende, izinhlangano zamabhizinisi kanye nabangane abavela kuzo zonke izingxenye zomhlaba ukuthi bakhulume nathi futhi bafune ukubambisana ngezici ezinhle zombili.
Siyazi ukuthi siyachuma kuphela uma singaqinisekisa kalula ukuncintisana kwethu kwamanani ahlanganisiwe kanye nenzuzo enhle ngesikhathi esifanayo, Manje kufanele siqhubeke nokugcina ifilosofi yebhizinisi "esezingeni eliphezulu, enemininingwane, esebenza kahle" yomoya wenkonzo "othembekile, onomthwalo wemfanelo, osungula izinto ezintsha", silandele inkontileka futhi silandele idumela, izimpahla zezinga eliphezulu futhi sithuthukise isevisi, samukele amakhasimende aphesheya kwezilwandle.
3,3 ', 4,4′ – I-Biphenyltetracarboxylic dianhydride iyinto ebalulekile ye-polyimide monomer enezinhlelo zokusebenza eziningi ekuhlanganisweni kwezinto ze-polyimide ezingamelana nokushisa okuphezulu. Isetshenziselwa ukukhiqizwa kwemikhiqizo ye-polyimide nezinto zayo ezihlanganisiwe, izinto ezisetshenziswa emithini.
I-CAS 2420-87-3 ye-3,3′,4,4′-I-Biphenyltetracarboxylic dianhydride iyisakhiwo esikhethekile kanye ne-compound ye-aromatic dianhydride esebenza kahle kakhulu, futhi iyi-monomer eyinhloko yokwenziwa kwezinto ze-polymer ezisebenza kahle kakhulu. Inendawo yokusetshenziswa engenakuphindwa emikhakheni efana ne-aerospace, ulwazi lwe-elekthronikhi, kanye nemishini ephezulu.

I-3,3′,4,4′-Biphenyltetracarboxylic dianhydride (i-CAS 2420-87-3, efingqiwe njenge-BPDA) iyi-monomer eyinhloko yokwenza izinto ze-polymer ezisebenza kahle kakhulu, futhi ukusetshenziswa kwayo kugxile kakhulu ensimini yezinto ezisezingeni eliphezulu.
1. I-dianhydride engu-3,3′,4,4′-Biphenyltetracarboxylic isetshenziswa njengezingxenye zesakhiwo ezimelana nokushisa okuphezulu zemikhumbi-mkhathi (njengezingxenye zendawo zezingxenye zesathelayithi) kanye nezingubo zokuvikela ukufudumala zezingxenye zenjini; I-substrate ye-antenna eguquguqukayo yemishini kanye nesendlalelo sokuvikela ukufudumala kwekhebula esimelana nokushisa okuphezulu.
2. I-BPDA ingasetshenziswa kumasekethe ahlanganisiwe (ama-ics): ukulungiselela amafilimu okuvikela angaphakathi kwezingqimba, ukunciphisa ukuguquguquka kobukhulu okubangelwa ukushisa kwama-chip, nokuthuthukisa ukuzinza kwama-chip. Yenziwe ngezinto ezihlanganisiwe ze-PI (njenge-carbon fiber egcwele kanye ne-graphite), ezisetshenziswa kuma-bearings kanye nama-seal ngaphansi kwezimo zokusebenza ezishisa kakhulu (njengokuvala izingxenye zezinjini zezimoto kanye nemishini yamakhemikhali), ukufaka esikhundleni sezinto zensimbi ukunciphisa ukuguguleka nokugqwala.
3. Ngaphandle kwe-polyimide, i-BPDA ingasabela nama-monomers ahlukene ukuze yakhe ezinye izinto ze-polymer ezisebenzayo, yandisa imingcele yokusetshenziswa kwayo
I-polyamideimide (PAI) yokwenziwa: I-BPDA iphendula ne-diisocyanate ukuze yakhe i-PAI. Lolu hlobo lwezinto luhlanganisa ukumelana nokushisa okuphezulu kwe-PI kanye nokumelana nomthelela kwe-polyamide, futhi lungasetshenziswa ukulungiselela izingxenye zepulasitiki zobunjiniyela eziphezulu.
I-polyetherimide yokwenziwa (i-PEI): Isabela nama-diamine aqukethe izibopho ze-ether ukuze yakhe i-PEI. Ukusebenziseka kwayo kuphakeme kunokwe-PI yendabuko. Ingenziwa ibe amagobolondo amadivayisi kagesi kanye nezixhumi ezimelana nokushisa okuphezulu ngokubumba umjovo, kucatshangelwa kokubili amandla kanye nokusebenziseka kalula.
4. Amaqembu e-anhydride ku-molecule ye-BPDA angabhekana nokusabela kokuvula indandatho namaqembu e-epoxy e-epoxy resin futhi asetshenziswe njengezinto zokupholisa ezimelana nokushisa okuphezulu:
I-4,4′-Biphthalic Anhydride 2420-87-3 isetshenziswa kakhulu ekulungiseleleni “izinto ezihlanganisiwe ze-epoxy ezingamelana nokushisa okuphezulu”, njengokuqiniswa kwezimpande zama-wind turbine blades (okudingeka zimelane nokuguga kwangaphandle kokushisa okuphezulu isikhathi eside) kanye nokuqiniswa kwe-epoxy substrates zamabhodi wesekethe aphezulu, ukuthuthukisa ukuzinza kokushisa (i-Tg yezinto eziqinisiwe ingandiswa ibe ngaphezu kuka-180℃) kanye namandla okusebenza ezinto ze-epoxy.
Ngokuvamile kupakishwe ku-25kg/isigubhu, futhi kungenziwa ngezifiso.
Siyazi ukuthi siyachuma kuphela uma singaqinisekisa kalula ukuncintisana kwethu kwamanani ahlanganisiwe kanye nenzuzo enhle ngesikhathi esifanayo kuMenzi we-OEM 3, 3′, 4, 4′-Biphenyltetracarboxylic Dianhydride/Bpda CAS 2420-87-3 we-Organic Synthesis, Samukela amakhasimende, izinhlangano zamabhizinisi kanye nabangane abavela kuzo zonke izingxenye zomhlaba ukuthi bakhulume nathi futhi bafune ukubambisana ngezici ezinhle zombili.
Umkhiqizi we-OEM 3 3'44′-Biphenyltetracarboxylic Dianhydride kanye ne-Bpda, Manje kufanele siqhubeke nokugcina ifilosofi yebhizinisi "esezingeni eliphezulu, enemininingwane, esebenza kahle" yomoya wenkonzo "othembekile, onomthwalo wemfanelo, osungula izinto ezintsha", silandele inkontileka futhi silandele idumela, izimpahla zekilasi eliphezulu futhi sithuthukise isevisi yamukelekile amakhasimende aphesheya kwezilwandle.
