Izinhlobo ze-graphite zingahlanzwa kanjani?

Ngokuvamile, lapho inqubo yokubumba isiqediwe, ukungcola noma izinsalela (ezinothileukwakheka kwamakhemikhalifuthiizakhiwo ezibonakalayo) zivame ukushiywa ku-isikhunta se-graphite. Ngezinhlobo ezahlukene zezinsalela, izidingo zokugcina zokuhlanza zihlukile. Ama-resin afana ne-polyvinyl chloride azokhiqiza igesi ye-hydrogen chloride, ezogqwala izinhlobo eziningi zensimbi ye-graphite mold. Ezinye izinsalela zihlukaniswa nezinto ezivimbela ilangabi kanye nama-antioxidants, okungabangela ukugqwala kwensimbi. Kukhona nezinye izinto ezifaka umbala we-pigment ezingagqwala insimbi, futhi ukugqwala kunzima ukukususa. Ngisho namanzi avaliwe ajwayelekile, uma eshiywa ebusweni be-graphite mold engakaphathwa isikhathi eside kakhulu, azophinde abangele umonakalo kwi-graphite mold.

Ngakho-ke, isikhunta se-graphite kufanele sihlanzwe njengoba kudingeka ngokomjikelezo wokukhiqiza omisiwe. Njalo lapho isikhunta se-graphite sikhishwa emshinini wokucindezela, izimbobo zesikhunta se-graphite kumele zivulwe ukuze kususwe yonke inhlabathi nokugqwala okuhlanganisiwe ezindaweni ezingabalulekile zesikhunta se-graphite kanye nethempulethi ukuze kuvinjelwe ukuthi kungagqwali kancane kancane ubuso kanye nemiphetho yensimbi. Ezimweni eziningi, ngisho nangemva kokuhlanza, ezinye isikhunta se-graphite esingagqokwanga noma esigqwalile sizophinde sibonise izimpawu zokugqwala. Ngakho-ke, noma ngabe kuthatha isikhathi eside ukugeza isikhunta se-graphite esingavikelwe, ukubonakala kokugqwala akukwazi ukugwenywa ngokuphelele.

Ngokuvamile, uma usebenzisa amapulasitiki aqinile, ubuhlalu beglasi, amagobolondo e-walnut kanye nama-pellet e-aluminium njengezinto zokubhula zokugaya nokuhlanza ubuso be-graphite molds ngokucindezela okukhulu, uma lezi zinto zokubhula zisetshenziswa kaningi noma ngokungafanele, le ndlela yokugaya izobangela nezinkinga. Ukubhoboka kwenzeka ebusweni be-graphite mold futhi izinsalela kulula ukuzinamathela, okuholela ezinsaleleni eziningi nasekugugeni, okungaholela ekuqhekekeni noma ekukhanyeni kwe-graphite mold ngaphambi kwesikhathi, okuyinto engathandeki kakhulu ekuhlanzweni kwe-graphite mold.

Manje, izikhunta eziningi ze-graphite zihlonyiswe ngamapayipi omoya “azihlanzayo”, anokukhanya okuphezulu. Ngemva kokuhlanza nokupholisha imbobo yomoya ukuze kufinyelelwe ezingeni lokupholisha le-SPI#A3, mhlawumbe ngemva kokugaya noma ukugaya, izinsalela zikhishwa ziye endaweni kadoti yepayipi lomoya ukuze kuvinjelwe izinsalela ukuthi zinganamatheli ebusweni besitendi esigoqekayo. Kodwa-ke, uma opharetha ekhetha ama-wash pads aqinile, indwangu ye-emery, i-sandpaper, amatshe okugaya, noma amabhulashi ane-nylon bristles, ithusi noma insimbi yokugaya isikhunta se-graphite ngesandla, kuzobangela “ukuhlanza” ngokweqile kwesikhunta se-graphite.

Ngakho-ke, ngemva kokufuna imishini yokuhlanza efanelekela isikhunta se-graphite kanye namasu okucubungula, kanye nokubhekisela ezindleleni zokuhlanza kanye nemijikelezo yokuhlanza eqoshwe kumafayela engobo yomlando, isikhathi sokulungisa esingaphezu kuka-50% singagcinwa, futhi ukuguguleka kwesikhunta se-graphite kungancishiswa ngempumelelo.
