Indlela yokuhlanza isikhunta se-graphite?

Ngokuvamile, lapho inqubo yokubumba isiqediwe, ukungcola noma izinsalela (ezinokwakheka kwamakhemikhali athile kanye nezakhiwo ezibonakalayo) zivame ukushiywa phezuisikhunta se-graphite. Ngezinhlobo ezahlukene zezinsalela, izidingo zokuhlanza nazo zihlukile. Ama-resin afana ne-polyvinyl chloride akhiqiza igesi ye-hydrogen chloride, ebese igqwalisa izinhlobo eziningi ze-graphite die steel. Ezinye izinsalela zihlukaniswa nezinqamuleli zomlilo kanye nama-antioxidants futhi zingabangela ukugqwala kube yinsimbi. Eminye imibala ye-pigment izogqwala insimbi, futhi ukugqwala kunzima ukukususa. Ngisho namanzi avamile avaliwe, uma ebekwe phezu kwesikhunta se-graphite esingalashwanga isikhathi eside, azophinde abangele umonakaloisikhunta se-graphite.
Ngakho-ke, isikhunta se-graphite kufanele sihlanzwe ngokuvumelana nomjikelezo wokukhiqiza omisiwe. Ngemva kokuba isikhunta se-graphite sikhishiwe emshinini wokunyathelisa ngaso sonke isikhathi, qala uvule imbobo yomoya ye-graphite ukuze ususe konke ukungcola kwe-oxidation nokugqwala ezindaweni ezingabalulekile zesikhunta se-graphite nesifanekiso, ukuze uvimbele ukugqwala kancane kancane kwendawo yensimbi. kanye nomphetho. Ezimweni eziningi, ngisho nangemva kokuhlanza, ezinye isikhunta esinganandisiwe noma esigqwalile se-graphite sizophinde sibonise ukugqwala. Ngakho-ke, ngisho noma kuthatha isikhathi eside ukugeza isikhunta esingavikelekile se-graphite, ukugqwala kokubukeka akukwazi ukugwema ngokuphelele.
Ngokuvamile, lapho amapulasitiki aqinile, ubuhlalu bengilazi, amagobolondo e-walnut kanye nezinhlayiya ze-aluminium kusetshenziswa njengama-abrasiveshigh-pressureukuchotshozwa nokuhlanza ubuso besikhunta se-graphite, uma lezi ziqhumane zisetshenziswa kaningi noma ngokungafanele, le ndlela yokugaya izophinde yenze ama-pores ebusweni besikhunta se-graphite futhi kube lula ukuthi izinsalela zinamathele kukho, okuholela ezinsalela eziningi futhi zigqoke, kungase kuholele ekuqhekekeni ngaphambi kwesikhathi noma ekuqhumeni kwesikhunta se-graphite, okungekuhle kakhulu ekuhlanzeni isikhunta se-graphite.
Manje, isikhunta esiningi se-graphite sinemigqa “ezihlanzayo,” enokukhanya okuphezulu. Ngemva kokuhlanza nokupholisha imbobo yokukhipha umoya ukuze kufinyelele izinga lokupholisha le-spi#a3, noma ukugaya noma ukugaya, khipha insalela endaweni kadoti yepayipi lokungenisa umoya ukuze uvimbele okusalelayo ekubambeleleni ebusweni besisekelo sokugaya. Kodwa-ke, uma opharetha ekhetha i-gasket ye-coarse-grained flushing, indwangu ye-emery, i-sandpaper, i-grindstone noma ibhulashi eline-nylon bristle, ithusi noma insimbi ukuze agaye isikhunta se-graphite ngesandla, kuzodala "ukuhlanza" ngokweqile kwesikhunta se-graphite.
Ngakho-ke, ngokufuna imishini yokuhlanza efanele isikhunta se-graphite kanye nobuchwepheshe bokucubungula nokubhekisela ezindleleni zokuhlanza kanye nemijikelezo yokuhlanza ebhalwe emibhalweni egciniwe, ngaphezu kwe-50% yesikhathi sokulungisa ingasindiswa futhi ukugqokwa kwesikhunta se-graphite kungancishiswa ngokuphumelelayo. .
