Indlela yokuphepha ukubola kwezixhobo nge-corrosive medium, ukwenzela ukunciphisa utyalo-mali lwezixhobo kunye nokugcinwa kweendleko kunye nokuphucula ukusebenza kakuhle kwemveliso kunye nenzuzo yingxaki enzima ukuba yonke ishishini lemichiza kufuneka liyisombulule ngonaphakade. Iimveliso ezininzi zinokumelana nokukhula kodwa azikwazi ukumelana nobushushu obuphezulu, ngelixa i-flake graphite ineenzuzo zombini. Okulandelayo FuruiteIgraphiteyazisa ngokweenkcukacha indlela i-flake graphite enokusombulula ngayo ingxaki yokubola kwezixhobo:
1. Ukuqhuba kakuhle kwe-thermal.I-Flake yegraphiteKwakhona ine-conductivity entle ye-thermal, eyona nto kuphela ye-non-metallic conductivity ephezulu ye-thermal conductivity kune-metal, ibeka kuqala phakathi kwezinto ezingezona zetsimbi. I-thermal conductivity iphindwe kabini i-carbon steel kunye namaxesha asixhenxe ensimbi engenasici. Ngoko ke, ifanelekile kwizixhobo zokudlulisa ubushushu.
2. Ukumelana nokugqwesa okugqwesileyo. Iindidi ezahlukeneyo zekhabhoni kunye negraphite zinokuxhathisa okugqwesileyo kokutya kuzo zonke izigxina ze-hydrochloric acid, i-phosphoric acid kunye ne-hydrofluoric acid, kubandakanya nemidiya ene-fluorine, kwaye olona bushushu besicelo luphezulu yi-350 ℃-400 ℃, oko kukuthi, iqondo lobushushu apho ikhabhoni kunye igraphite iqala ukwenza oxidize.
3, ukumelana nobushushu obuthile obuphezulu. Ubushushu bokusetyenziswa kwe-flake yegraphite kuxhomekeke kwiindidi zezinto zokumitha. Umzekelo, i-phenolic impregnated graphite inokumelana ne-170-200℃, kwaye ukuba isixa esifanelekileyo se-silicone resin efakwe igraphite efakiweyo, inokumelana ne-350℃. Xa i-asidi ye-phosphoric ifakwe kwikhabhoni kunye negraphite, ukunyanzeliswa kwe-oxidation yekhabhoni kunye negraphite kunokuphuculwa, kwaye ukushisa kwangempela kokusebenza kunokunyuka ngakumbi.
4, umphezulu akukho lula ukwakha. "Ubudlelwane" phakathi kwe-flake graphite kunye nemidiya eninzi incinci kakhulu, ngoko ke ukungcola akulula ukunamathela kumphezulu. Ngokukodwa isetyenziswe kwizixhobo ze-condensation kunye nezixhobo zecrystallization.
Kuyabonakala ukuba izixhobo ezine-flake graphite zinokumelana nokugqwesa okugqwesileyo kunye neempawu zomzimba nezomatshini, kwaye zingasetyenziselwa ukwenza izixhobo zokulwa nokubola kunye nokusasazeka kwishishini lemichiza.
