Filler graphite, bi ñuy jëfandikoo macceer bu kawe- bu kawe, ñu ngi koy jëfandikoo bu bari ci wàllu chimik, petroleum, ak ci kuuraŋ. Li muy defar dafay indi jafe-jafe ci dëgëraay bi, bañaale korosion bi, ak doole mekanik bi. Muy wax ci xët wii di wax ci anam wu leer, defar filler graphite ak ay poñam yu am solo ci wàllu xarala.
Li gëna am solo ci defar filler braphite mooy pressing, extrusion, ak moule compression. Molage commion mooy anam wi gëna bari, méngoo ak macceer graphite graphite wala granular. Doxalin bii dafay jëfandikoo ab pres hydraulique wala mekanik ngir jaxase poudre graphite ak benn binder, ba noppi nga tëye ko ci forme bi nga bëgg ci tàngoor ak pression bu kawe. Ci jamonoy pressing, pression uniforme dafa am solo ci dëgëraay bi ak dooley produit bi mujj. Presure dañu koy faral di saytu diggante 10 ba 30 MPa, te tàngoor wi dafay wéy di am diggante 150 ba 300 degre ngir gëna yombal li ñuy woowe lignéer bi.
Molding extrusion bi baaxna ci defar baton wala tube graphite. Li ci nekk mooy njaxasu macceer bu bees bi, rayoy, extrusion ak waw. Poudre graphite ak benn linder (lu melni resin phenolic wala asphalte) dañu leen jaxase bu baax ci biir benn kees ngir defar benn slurry plastik bu nekk. Suko defee ñu ngi koy génne ci benn cross- ci jëmm ji. Molding extrusion dafay laaj jëmmal bu kawe ngir mëna am slurry buy daw ba noppi moytu def ay njuumte ci biir. Produit biñ defar dafay am {6} Mimpérature kalsitaasioŋ ngir dindi komponent yi ci biir binder bi ak gëna suqali grafite bi.
Moldage commion bi baaxna ci- gramite graphite yu am formu, lu ci melni gaskets wala paketu annule. Process bi mooy jaxase poudre graphite ak benn linder ci ratio bi méngoo, nga boole njaxas mi ci moule metal bu tàng, ba noppi nga def pression ci mold bi ci jëfandikoo press. Caabi bi ci moulage compression mooy saytu tolluwaayu tàngoor wi ak waxtu wi war ngir mëna am structure interne bu dëgër te doo delamination. Tàngooru calcination mingi tollu ci diggante 800 degre ak 1200 degre ngir gëna mëna yokk grafite bi {6}) température ak stabilite chimik.
Tanneef binder itam dafa am solo ci liggéey bi ci moule graphite. Lindon yu bari ñooy resin yi, oxide yi ak asphalte. Lindert yu wuute yi dañuy indi jafe-jafe ci doxalinu tàngooru mbir yi, bañaale corrosion bi, ak doole mekanik. Ci misaal, resin phenolic mingi méngoo ak diggante- ak- ci environmaa yi, ci noonu la lien metal (lu melni poudre copper) mën na gëna baaxal resistance bi filler bi ak doxalinu thermique.
Ci gàttal, fàww ñu gëna mëna defar anam wi ñuy jëfandikoo ngir defar graphite ci anam wu lalu ci màndarga yiñ soxla, jëfandikoo gi, ak anam yi jumtukaay yi di doxee. Bu ñuy saytu bu baax pression bi, tàngoor wi, ak ratio binder, mën nañu defar ay mbir yu am solo ci grafite graphite ngir mëna faj jafe-jafe yu mag yi ci corrosion-restant, bu kawe-testant, ak {5} dundu.
