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-antioxidant kwaye zinokubangela ukubola kwintsimbi. Ezinye ii-pigment colorants ziya kugqwala intsimbi, kwaye umhlwa kunzima ukuwususa. Kwanamanzi atywiniweyo ngokubanzi, ukuba abekwe phezu komphezulu we-graphite ukungunda okungaphendulwanga ixesha elide, kuya kubangela umonakaloukungunda kwegraphite.
Ke ngoko, i-graphite mold kufuneka icocwe ngokomjikelezo wemveliso omiselweyo. Emva kokuba ukungunda kwegraphite kukhutshiwe kumatshini ngalo lonke ixesha, vula kuqala umngxuma womoya wokubumba igraphite ukuze ususe konke ukungcola kwe-oxidation kunye nomhlwa kwiindawo ezingabalulekanga zokungunda kwegraphite kunye netemplate, ukuze uyithintele ukuba ingagqwali kancinci umphezulu wentsimbi. kunye nomphetho. Kwiimeko ezininzi, nasemva kokucocwa, ezinye ii<em>graphite 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 ukungunda igraphite, ukuba ezi abrasives zisetyenziswa rhoqo kakhulu okanye ngokungafanelekanga, le ndlela yokusila nayo iya kwenza iipores kumphezulu wegraphite ngundo kwaye kube lula ukuba iintsalela zibambelele kuyo, kubangele iintsalela ezininzi kunye nokunxiba, kunokukhokelela ekuqhekekeni kwangaphambi kwexesha okanye i-burr ye-graphite mold, engathandekiyo ekucoceni ukungunda kwegraphite.
Ngoku, ii<em>graphite 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 ukunxiba kwe-graphite mold kunokunciphisa ngokufanelekileyo. .
