Isikhunta se-graphite singahlanzwa kanjani?

Ngokuvamile, lapho inqubo yokubumba isiqediwe, ukungcola noma izinsalela (ngokuqinisekileukwakheka kwamakhemikhalifuthiizakhiwo zomzimba) zivame ukushiywa ku-isikhunta se-graphite. Ngezinhlobo ezahlukene zezinsalela, izidingo zokugcina zokuhlanza zihlukile. Ama-resin afana ne-polyvinyl chloride azokhiqiza igesi ye-hydrogen chloride, ezogqwalisa izinhlobo eziningi zensimbi ye-graphite mold. Ezinye izinsalela zihlukaniswa nezinqamuli zomlilo kanye nama-antioxidants, angabangela ukugqwala kube yinsimbi. Kukhona neminye imibala ye-pigment ekwazi ukugqwala insimbi, futhi ukugqwala okunzima ukukususa. Ngisho namanzi avamile avaliwe, uma eshiywe phezu kwesikhunta se-graphite esingalashiwe isikhathi eside, azophinde abangele ukulimala kwesikhunta se-graphite.

Ngakho-ke, isikhunta se-graphite kufanele sihlanzwe njengoba kudingekile ngokuvumelana nomjikelezo wokukhiqiza omisiwe. Ngaso sonke isikhathi lapho isikhunta se-graphite sikhishwa emshinini wokunyathelisa, izimbotshana zesikhunta se-graphite kufanele zivuleke ukuze kukhishwe konke ukungcola okune-oxidized kanye nokugqwala ezindaweni ezingabalulekile zesikhunta se-graphite nesifanekiso ukuze kuvinjwe ukugqwala kancane kancane kwendawo nasemaphethelweni. okwensimbi. Ezimweni eziningi, ngisho nangemva kokuhlanzwa, ezinye isikhunta esinganandisiwe noma esigqwalile se-graphite ngokushesha sizophinde sibonise izimpawu zokugqwala. Ngakho-ke, ngisho noma kuthatha isikhathi eside ukugeza isikhunta esingavikelekile se-graphite, ukubonakala kokugqwala akukwazi ukugwenywa ngokuphelele.

Ngokuvamile, uma usebenzisa ama-plastiki aqinile, ubuhlalu bengilazi, amagobolondo e-walnut kanye nama-pellets e-aluminium njengama-abrasives okugaya okuphezulu kokucindezela nokuhlanza ubuso besikhunta se-graphite, uma lezi ziqhumane zisetshenziswa kaningi noma ngokungafanele, le ndlela yokugaya izophinde ibangele izinkinga. I-porosity yenzeka ebusweni besikhunta se-graphite futhi izinsalela kulula ukunamathela kuso, okuholela ezinsalela eziningi nokugqoka, okungase kuholele ekuqhekekeni ngaphambi kwesikhathi noma ukukhanya kwesikhunta se-graphite, okungathandeki kakhulu ekuhlanzeni isikhunta se-graphite.

Manje, isikhunta esiningi se-graphite sifakwe amapayipi “azihlanzayo,” anokukhanya okuphezulu. Ngemva kokuhlanza nokupholisha imbobo yokukhipha umoya ukuze kufinyelelwe izinga lokupholisha le-SPI#A3, mhlawumbe ngemva kokugaya noma ukugaywa, insalela ikhishelwa endaweni kadoti yepayipi lokungenisa umoya ukuze kuvinjelwe okusele ekubambeleleni ebusweni bokugoqeka. yima . Kodwa-ke, uma umqhubi ekhetha ama-coarse-grained wash pads, emery cloth, sandpaper, amatshe okugaya, noma amabhulashi ane-nylon bristles, ithusi noma insimbi ukuze agaye ngesandla isikhunta se-graphite, kuzodala "ukuhlanzwa" ngokweqile kwesikhunta se-graphite. .

Ngakho-ke, ngemva kokufuna imishini yokuhlanza efanele isikhunta se-graphite nezindlela zokucubungula, futhi ubhekisela ezindleleni zokuhlanza nemijikelezo yokuhlanza eqoshwe kumafayela agciniwe, ngaphezu kwe-50% yesikhathi sokulungisa singagcinwa, futhi ukugqokwa kwesikhunta se-graphite kungasindiswa. kuncishiswe ngempumelelo.
