Njira zopangira mawonekedwe olowetsedwa
Impregnation ndi gawo losasankha lomwe limapangidwa kuti apititse patsogolo mawonekedwe a chinthu chomaliza.Tars, Pitches, resins, zitsulo zosungunuka ndi ma reagents ena amatha kuwonjezeredwa ku mawonekedwe ophika (muzinthu zapadera mawonekedwe a graphite amathanso kulowetsedwa) ndi ma reagents ena amagwiritsidwa ntchito kudzaza ma voids omwe amapangidwa muzinthu za carbonised.Kuviikidwa ndi phula lotentha la malasha kapena opanda vacuum ndi autoclaving amagwiritsidwa ntchito.Njira zosiyanasiyana zoberekera zimagwiritsidwa ntchito kutengera zomwe zapangidwa, monga koma batch kapena ma quasi-continuous operations amagwiritsidwa ntchito.Kuzungulira kwa impregnation nthawi zambiri kumaphatikizapo kutenthetsa mawonekedwe, kulowetsedwa ndi kuziziritsa.Makina owumitsa amatha kugwiritsidwanso ntchito.Ma Electrodes omwe adzalowetsedwe amatha kutenthedwa ndi kutentha kwataya kwa oxidiser yamafuta.Ma carbons apadera okha ndi omwe amapangidwa ndi zitsulo zosiyanasiyana.The zophikidwa kapena graphised zigawo zikuluzikulu akhoza impregnated ndi zipangizo, mwachitsanzo resins kapena zitsulo.Impregnation imachitika ndikunyowa, nthawi zina pansi pa vacuum ndipo nthawi zina mopanikizika, ma autoclave amagwiritsidwa ntchito.Zida zomwe zidayikidwa kapena zomangidwa ndi phula la malasha zimachotsedwa.Ngati nsonga za resin zimagwiritsidwa ntchito, zimachiritsidwa.
Njira zopangira mawonekedwe obwezeretsedwa kuchokera ku mawonekedwe olowetsedwa
Kuphika ndi kuphikanso Kuphikanso kumangogwiritsidwa ntchito pamipangidwe yomwe idayikidwa.Mawonekedwe obiriwira (kapena mawonekedwe opangidwa ndi Impregnated) amawotchera pa kutentha mpaka 1300 ° C pogwiritsa ntchito ng'anjo zosiyanasiyana monga ngalande, chipinda chimodzi, zipinda zingapo, ng'anjo za annular ndi zokankhira kutengera kukula ndi zovuta za chinthucho.Kuphika kosalekeza kumapangidwanso.Ntchito za ng'anjo ndizofanana ndi zomwe zimagwiritsidwa ntchito pophika ma electrode, koma
ng'anjo nthawi zambiri amakhala ang'onoang'ono.
