Izakhiwo zomzimba namakhemikhali
- I-electrical conductivity: Amashidi e-graphite abonisa ukusebenza kahle kukagesi, ngokuyinhloko ngenxa yesakhiwo sawo esinengqimba esingu-π{{0}π esizinzile esakhiwe amafu e-electron e-π kanye{1}}ne-carbon covalent bond. Lokhu kulungiselelwa kunika amandla ukuthuthwa kwe-electron okusebenzayo ngaphakathi kwempahla, okuholela ekumelaneni okuphansi ngokukhethekile okungu-10^-6 Ω·m. Ngakho-ke, i-graphite isebenza njengento efanelekile ye-electrode.
- I-Thermal conductivity: Ipuleti le-graphite libuye libe ne-conductivity enhle kakhulu yokushisa, ukuqhutshwa kwayo okushisayo kuphakeme kunensimbi, insimbi, umthofu nezinye izinto zensimbi. Lokhu kungenxa yesakhiwo esinezingqimba kanye nesakhiwo sekristalu esihlelwe kakhulu se-graphite plate, ukuze amandla okushisa adluliselwe ngokuphumelelayo ngokusebenzisa ukudlidliza phakathi kwezingqimba.
- Izakhiwo zemishini: Ipuleti le-graphite linamandla aphezulu, ukuguquguquka okuphezulu kanye nokumelana nokukhala. I-modulus yayo Encane namandla esivuno angafinyelela ku-1 TPa kanye no-130 GPa ngokulandelanayo, okuyizikhathi ezingaphezu kwezingamashumi amabili kunezensimbi. Lawa mandla aphezulu enza i-graphite plate ibe nokuzinza okuhle kakhulu ekucindezelweni okuphezulu kanye nemvelo yokushisa ephezulu.
- Ukuzinza kwamakhemikhali: I-carbon-carbon bond ye-graphite plate inamandla ebhondi ephezulu kanye nokusebenza kabusha kwamakhemikhali aphansi, futhi inokumelana okuphezulu kumakhemikhali amaningi. Ama-asidi ambalwa kuphela nama-alkali angakwazi ukugqwala, ngakho-ke ipuleti le-graphite lisetshenziswa kakhulu ku-reactor yamakhemikhali kanye ne-catalyst carrier.
I-Precision{{0}I-Machined Graphite Plate isiphenduke into ebaluleke kakhulu-ekwenziweni okuphezulu ngenxa yokunemba kwayo okuphezulu, ukumelana nemvelo okudlulele kanye nokwenza ngokwezifiso okuqinile. Ukuze kuqinisekiswe ukusebenza okuhle kakhulu, ukuhlanzeka kwe-graphite, usayizi wezinhlayiyana, indlela yokucubungula kanye nokwelashwa kwendawo kufanele kucatshangelwe ngokucophelela lapho kukhethwa i-graphite.
Amashadi ashisayo: ukunemba-okunomshini we-graphite plate, ukunemba kwe-China{1}}abakhiqizi be-graphite plate abangomshini
