I-Pyromellitic DianhydrideCAS2420-87-3: “Ihhashi Elimnyama” Emkhakheni Wezinto Ezintsha Zamakhemikhali Likhanga Ukunaka Kwemboni

Muva nje, phakathi nentuthuko ekhulayo embonini yamakhemikhali, i-pyromellitic dianhydride (PMDA), inhlanganisela ebalulekile, iye yangena ngokuthula ekukhanyeni, yafaka ugqozi oluqinile emisha yezinto eziningi ezisezingeni eliphezulu futhi yaqala igagasi elisha lokuhlola kulo lonke imboni, izikhungo zemfundo ephakeme kanye nemiphakathi yocwaningo.

Njengezinto ezibalulekile zamakhemikhali aphilayo, i-pyromellitic dianhydride ingase ibonakale ingavamile ekuqaleni, kodwa empeleni inamakhono ahlukile. Kusukela ohlangothini lokukhiqiza, amabhizinisi amaningi amakhemikhali asekhaya aqinisa imizamo yawo yokuthuthukisa nokwandisa imigqa yawo yokukhiqiza. [Igama Lenkampani] Chemical Co., Ltd. isanda kuqeda ukwenza ngcono nokuthuthukisa inqubo yokukhiqiza ye-pyromellitic dianhydride. Ubuchwepheshe obusha busebenzisa uhlelo lokulawula oluhlakaniphile olulawula ngokunembile imingcele ebalulekile njengokushisa kokusabela kanye nokucindezela. Lokhu kukhulise ubumsulwa bomkhiqizo cishe ngamaphesenti ama-3 futhi kunciphisa kakhulu okuqukethwe kokungcola. Akugcini nje ngokuqinisekisa ukuzinza kwekhwalithi yemikhiqizo elandelayo kodwa futhi kuthuthukisa kakhulu ukusebenza kahle kokukhiqiza, ngokukhipha ngeyunithi ngayinye isikhathi kukhuphuka ngaphezu kwama-20%, okunikeza inkampani inzuzo yokuqala emakethe encintisana kakhulu.

Ensimini yokufaka isicelo, i-pyromellitic dianhydride ikhanya kakhulu. Amaqembu ocwaningo ahlala ehlola amandla ayo ekuthuthukisweni kwezinto ezisebenza kahle kakhulu. Ngokuphathelene nezinto ze-elekthronikhi, ifilimu ye-polyimide eyenziwe ngayo inobukhulu obuyisigamu nje sezinto zokufaka ugesi zendabuko, kodwa ingamelana nama-volts afinyelela kumakhulu amaningana ama-volts, ine-dielectric constant ezinzile, kanye nezakhiwo ezinhle kakhulu zokushabalalisa ukushisa, enikeza ikhambi elifanele enkingeni yokufaka ugesi nokupakisha ama-chip amancane, anembile kumadivayisi okuxhumana e-5G ngisho nasesikhathini esizayo e-6G. Ibhizinisi elihamba phambili lobuchwepheshe be-elekthronikhi lifinyelele ekubambisaneni okunesu nabahlinzeki bezinto zokusetshenziswa ezisezingeni eliphezulu futhi lihole ekuhloleni imikhiqizo yokupakisha ama-chip efakwe ifilimu entsha ye-polyimide, lilwela ukuba phambili emncintiswaneni wemikhiqizo yobuchwepheshe bokuxhumana besizukulwane esilandelayo.

Umkhakha wezindiza nawo awusaleli emuva. Ngenxa yezakhiwo zokushisa okuphezulu kanye nokumelana nemisebe yezinto ezenziwe nge-pyromellitic dianhydride, amapulasitiki obunjiniyela afanele asetshenziselwa ukukhiqiza izingxenye zokuvikela ezilula emaphethelweni amaphiko ezindiza. Uma kuqhathaniswa nezingxenye zensimbi zendabuko, zinciphisa isisindo ngaphezu kuka-30%, zinciphisa ngempumelelo ukusetshenziswa kukaphethiloli futhi zisize izimoto zezindiza ukundiza kude futhi zizinzile. Ngaphezu kwalokho, lapho izinto ezenziwe ngale nto zifakwa ezingqimbeni zangaphandle zokuvikela zezintambo ezikhethekile zama-space probe, zingamelana nemisebe ye-cosmic eyeqile kanye nokwehluka kwezinga lokushisa, ziqinisekise ukudluliswa kwedatha okuzinzile ngesikhathi sokuthunywa kwesikhala okuyinkimbinkimbi.
