Zviumbwa zve graphite zvingacheneswa sei?

Kazhinji, kana maitiro ekuumba apera, tsvina kana masara (nezvimwemakemikari anoumbwauyezvinhu zvemuviri) kazhinji vanosiiwa pagraphite mold. Kune marudzi akasiyana-siyana emasara, zvinodiwa zvekuchenesa zvekupedzisira zvakasiyana. Mishonga yakadai sepolyvinyl chloride inobudisa hydrogen chloride gasi, iyo inoparadza marudzi akawanda e graphite mold steel. Zvimwe zvisaririra zvakapatsanurwa kubva kune zvinodzosa moto uye ma antioxidants, izvo zvinogona kukonzera ngura kuita simbi. Kune zvakare mamwe mavara epigment anogona kuita ngura simbi, uye ngura yacho yakaoma kubvisa. Kunyangwe mvura yakavharwa yakazara, kana ikasiiwa pamusoro peiyo isina kucheneswa graphite mold kwenguva yakareba, inokonzeresa kukanganisa kune graphite mold.

Naizvozvo, iyo graphite mold inofanirwa kucheneswa sezvinodiwa zvinoenderana neyakagadzika kugadzirwa kutenderera. Nguva imwe neimwe iyo graphite mold inobudiswa kunze kwekudhinda, pores ye graphite mold inofanira kuvhurwa kuti ibvise tsvina yose ine oxidized uye ngura kubva munzvimbo dzisiri dzakakosha dze graphite mold uye template kudzivirira kuti irege kupera zvishoma nezvishoma pamusoro uye kumucheto. yesimbi. Muzviitiko zvakawanda, kunyange pashure pokuchenesa, zvimwe zviumbwa zvegraphite zvisina kuvharwa kana kuti zvine ngura zvichakurumidza kuratidza zviratidzo zvengura zvakare. Nokudaro, kunyange kana zvichitora nguva yakareba kushambidza isina kudzivirirwa graphite mold, kuonekwa kwemarara hakugoni kudziviswa zvachose.

Kazhinji, kana uchishandisa mapurasitiki akaoma, magirazi egirazi, walnuts shells uye aluminium pellets seabrasives ye-high-pressure grinding uye kuchenesa pamusoro pe graphite molds, kana mabrasives aya akashandiswa kakawanda kana zvisina kunaka, iyi nzira yekukuya ichakonzerawo matambudziko. Porosity inoitika pamusoro peiyo graphite mold uye masara ari nyore kuomerera kwairi, zvichikonzera mamwe masara uye kupfeka, izvo zvinogona kutungamirira kukukurumidza kuputika kana kupenya kwe graphite mold, iyo inonyanya kusafarira kucheneswa kwe graphite mold.

Iye zvino, molds dzakawanda dze graphite dzakagadzirirwa "self-cleaning" pombi dzinobuda, dzine kubwinya kwakakwirira. Mushure mekuchenesa nekupukuta gomba rekubuda panze kuti muwane kukwenenzverwa kweSPI#A3, pamwe mushure mekugaya kana kukuya, chinosara chinoraswa kunzvimbo yemarara yepombi yepombi kudzivirira zvakasara kuti zvisanamirane pamusoro peiyo rough rolling. stand . Zvisinei, kana mushandisi akasarudza mapedhi ekugezesa-grained, emery cloth, sandpaper, matombo ekukuya, kana mabhurashi ane nylon bristles, brass kana simbi kuti agaye ma graphite mold, zvinokonzeresa “kucheneswa” kwe graphite mold. .

Naizvozvo, mushure mekutsvaga michina yekuchenesa yakakodzera magirafu moulds uye nzira dzekugadzirisa, uye tichitaura nezve nzira dzekuchenesa uye kutenderera kutenderera kwakanyorwa mumafaira ekuchengetedza, kupfuura 50% yenguva yekugadzirisa inogona kuchengetwa, uye kupfeka kweiyo graphite mold inogona. kuderedzwa zvinobudirira.
