Ukugwema kanjani ukugqwala kwemishini nge-corrosion medium enamandla, ukuze kwehliswe izindleko zokutshala imali kanye nokugcinwa kwemishini futhi kuthuthukiswe ukusebenza kahle kokukhiqiza kanye nenzuzo kuyinkinga enzima ukuthi yonke inkampani yamakhemikhali idinga ukuyixazulula unomphela. Imikhiqizo eminingi inokumelana nokugqwala kodwa hhayi ukumelana nokushisa okuphezulu, kuyilapho i-flake graphite inezinzuzo zombili. Okulandelayo FuruiteI-graphiteyethula ngokuningiliziwe ukuthi i-flake graphite ingaxazulula kanjani inkinga yokugqwala kwemishini:
1. Excellent conductivity ezishisayo.Faka i-graphitefuthi ine-thermal conductivity enhle, okuwukuphela kwento engeyona eyensimbi ene-thermal conductivity ephakeme kunensimbi, ibekwe kuqala phakathi kwezinto ezingezona ezensimbi. I-thermal conductivity iphindwe kabili kune-carbon steel futhi iphindwe kasikhombisa kunensimbi engagqwali. Ngakho-ke, kufanelekile imishini yokudlulisa ukushisa.
2. Ukumelana nokugqwala okuhle kakhulu. Izinhlobo ezahlukahlukene zekhabhoni negraphite zinokumelana nokugqwala okuhle kakhulu kukho konke ukugxila kwe-hydrochloric acid, i-phosphoric acid ne-hydrofluoric acid, kufaka phakathi imidiya equkethe i-fluorine, futhi izinga lokushisa eliphakeme kakhulu lesicelo ngu-350℃-400℃, okungukuthi, izinga lokushisa lapho ikhabhoni kanye I-graphite iqala ukukhiqiza i-oxidize.
3, ukumelana nezinga lokushisa elithile eliphakeme. Izinga lokushisa lokusetshenziswa kwe-flake graphite lincike ezinhlobonhlobo zezinto zokufaka isisu. Isibonelo, i-phenolic impregnated graphite ingamelana nokungu-170-200℃, futhi uma inani elifanele le-silicone resin efakwe igraphite ingezwa, ingamelana no-350℃. Uma i-phosphoric acid ifakwa ku-carbon ne-graphite, ukumelana ne-oxidation ye-carbon ne-graphite kungathuthukiswa, futhi izinga lokushisa langempela lokusebenza lingakhuphuka ngokuqhubekayo.
4, ebusweni akulula ukwakha. "Ukuhlobana" phakathi kwe-flake graphite kanye nemidiya eminingi kuncane kakhulu, ngakho ukungcola akulula ukunamathela phezulu. Ikakhulukazi esetshenziswa imishini condensation kanye crystallization imishini.
Kungabonakala ukuthi imishini ene-flake graphite inokumelana nokugqwala okuhle kakhulu kanye nezakhiwo zomzimba nezomshini, futhi ingasetshenziswa ukwenza imishini yokulwa nokugqwala futhi isakaze kabanzi embonini yamakhemikhali.
