Indlela yokuphepha ukugqwala kwezixhobo ngokusebenzisa indlela enamandla yokugqwala, ukuze kuncitshiswe iindleko zotyalo-mali kunye nokugcinwa kwezixhobo kunye nokuphucula ukusebenza kakuhle kwemveliso kunye nenzuzo yingxaki enzima ekufuneka isonjululwe yinkampani nganye yamachiza ngonaphakade. Iimveliso ezininzi zinokumelana nokugqwala kodwa azinakumelana nobushushu obuphezulu, ngelixa i-graphite ye-flake ineenzuzo zombini. I-Furuite elandelayoIgrafayithiyazisa ngokweenkcukacha indlela i-flake graphite enokuyisombulula ngayo ingxaki yokugqwala kwezixhobo:
1. Ukuqhuba kakuhle kobushushu.I-graphite ye-Flakeikwanayo ne-thermal conductivity elungileyo, eyiyeyona nto ingenasinyithi eno-thermal conductivity ephezulu kune-metal, ibekwa kwindawo yokuqala phakathi kwezinto ezingezizo zesinyithi. I-thermal conductivity iphindwe kabini kune-carbon steel kwaye iphindwe kasixhenxe kune-stainless steel. Ke ngoko, ifanelekile kwizixhobo zokudlulisa ubushushu.
2. Ukumelana nokugqwala okugqwesileyo. Iintlobo ngeentlobo zekhabhoni kunye negrafiti zinokumelana nokugqwala okugqwesileyo kuzo zonke iindawo ze-hydrochloric acid, i-phosphoric acid kunye ne-hydrofluoric acid, kubandakanya ne-fluorine-containing media, kwaye ubushushu obuphezulu bokusetyenziswa yi-350℃-400℃, oko kukuthi, ubushushu apho ikhabhoni kunye negrafiti ziqala khona ukugqwala.
3, ukumelana nobushushu obuphezulu obuthile. Ubushushu bokusetyenziswa kwe-flake graphite buxhomekeke kwiindidi zezinto ezifunxayo. Umzekelo, i-phenolic graphite efunxayo inokumelana ne-170-200℃, kwaye ukuba kongezwa isixa esifanelekileyo se-silicone resin graphite efunxayo, inokumelana ne-350℃. Xa i-phosphoric acid ifakwa kwi-carbon kunye ne-graphite, ukumelana ne-oxidation ye-carbon kunye ne-graphite kunokuphuculwa, kwaye ubushushu bokusebenza bunokwandiswa ngakumbi.
4, umphezulu awulula ukuwubumba. "Ubudlelwane" phakathi kwegrafiti ye-flake kunye ne-media eninzi buncinci kakhulu, ngoko ke ukungcola akulula ukunamathela kumphezulu. Isetyenziswa ngakumbi kwizixhobo zokufunxa kunye nezixhobo ze-crystallization.
Kuyabonakala ukuba izixhobo ezinegrafiti ye-flake zinokumelana nokugqwala okugqwesileyo kunye neempawu zomzimba nezoomatshini, kwaye zingasetyenziselwa ukwenza izixhobo zokulwa nokugqwala kwaye zisasazeke kakhulu kushishino lweekhemikhali.
