Indlela yokucoca i-graphite mold?

Ngokubanzi, xa inkqubo yokubumba igqityiwe, ukungcola okanye iintsalela (kunye nokwakheka kweekhemikhali ezithile kunye neempawu ezibonakalayo) zihlala zishiyekaukungunda kwegraphite. Kwiintlobo ezahlukeneyo zeentsalela, iimfuno zokucoca nazo zahlukile. Iintlaka ezifana ne-polyvinyl chloride zivelisa igesi ye-hydrogen chloride, ethi ke idle iintlobo ezininzi ze-graphite die steel. Ezinye iintsalela zohlulwe kwi-flame retardants kunye ne-antioxidants kwaye zinokubangela ukubola kwintsimbi. Ezinye ii-pigment colorants ziya kugqwala intsimbi, kwaye umhlwa kunzima ukuwususa. Kwanamanzi atywiniweyo ngokubanzi, ukuba abekwe phezu komphezulu we-graphite mold engaphathwanga ixesha elide, iya kubangela umonakaloukungunda kwegraphite.
Ke ngoko, i-graphite mold kufuneka icocwe ngokomjikelezo wemveliso omiselweyo. Emva kokuba i-graphite mold ikhutshwe kwi-press lonke ixesha, vula kuqala i-graphite mold air hole ukususa yonke i-oxidation ye-oxidation kunye ne-rust kwiindawo ezingabalulekanga kwi-graphite mold kunye ne-template, ukuze uthintele ukuba uthintele ngokucothayo ukugqwesa umphezulu wentsimbi kunye nomphetho. Kwiimeko ezininzi, nasemva kokucocwa, ezinye iigraphite ezibumbayo ezingagqunywanga okanye ezirusayo ziya kuphinda zibonise umhlwa kwakhona. Ngoko ke, nokuba kuthatha ixesha elide ukuhlamba i-graphite mold engakhuselekanga, ukubonakala kwe-rust ayikwazi ukuphetshwa ngokupheleleyo.
Ngokubanzi, xa iiplastiki eziqinileyo, amaso eglasi, amaqokobhe e-walnut kunye namasuntswana e-aluminiyam asetyenziswa njengeziqhoboshi.uxinzelelo oluphezuluukutyunyuzwa kunye nokucocwa komphezulu ngundo graphite, ukuba ezi abrasives zisetyenziswa rhoqo kakhulu okanye ngokungafanelekanga, le ndlela yokugaya iya kwenza kwakhona iipores kumphezulu we-graphite ngundo kwaye kulula ukuba iintsalela zibambelele kuyo, okubangela iintsalela ezininzi kunye nokunxiba, Inokukhokelela ekuqhekekeni kwangaphambi kwexesha okanye i-burr ye-graphite yokubumba i-mold engenakulinganiswa nokucoca i-mold ye-graphite engaphezulu, enokucocwa ngakumbi kwi-mold.
Ngoku, iigraphite ezininzi zokubumba zinemigca “ezicocayo” ephumayo, eneglosi ephezulu. Emva kokucoca kunye nokugudisa umngxuma wokuphuma ukuze ufikelele kwinqanaba lokugulisa le-spi#a3, okanye ukugawula okanye ukugaya, khupha intsalela kwindawo yenkunkuma yombhobho wokukhupha umoya ukukhusela intsalela ekubambeleleni kumphezulu wesiseko sokusila. Nangona kunjalo, ukuba umqhubi ukhetha i-gasket ye-coarse-grained flushing, ilaphu le-emery, i-sandpaper, i-grindstone okanye i-brush nge-nylon bristle, ubhedu okanye intsimbi yokugaya i-graphite mold ngesandla, kuya kubangela "ukucoca" ngokugqithiseleyo kwe-graphite mold.
Ngoko ke, ngokukhangela izixhobo zokucoca ezifanelekileyo kwi-graphite mold kunye ne-processing technology kunye nokubhekisela kwiindlela zokucoca kunye nemijikelezo yokucoca erekhodiweyo kumaxwebhu agciniweyo, ngaphezu kwe-50% yexesha lokulungiswa kunokugcinwa kwaye ukugqoka i-graphite mold kunokunciphisa ngokufanelekileyo.
