Alaabta
saxan graphite electrode
Astaamaha
Waxyaabaha cayriin ee loo isticmaalo soo saarista taarikada garaafka waa labajibbaaran garaafka: qeexitaannada caadiga ah iyo xoogga sare, cufnaanta sare ee graphite waxay isticmaalaan kookaha batroolka wanaagsan sida alaabta ceeriin.Qaadashada hababka wax soo saarka sare iyo qalabka, alaabtu waxay leeyihiin sifooyinka cufnaanta sare, cadaadiska sare iyo xoogga dabacsanaanta, porosity hooseeya, iska caabinta daxalka, acid iyo caabbinta alkali, iwm. qalabka, qalabka kiimikada, caaryada farsamada, iyo qaybaha garaafyada qaab gaar ah.
1. Waxay leedahay faa'iidooyinka caabbinta heerkulka sare, habdhaqanka wanaagsan iyo kuleylka kuleylka, farsamaynta farsamada fudud, xasiloonida kiimikada wanaagsan, caabbinta aashitada iyo alkali, iyo content ash hoose;
2. Loo isticmaalo electrolysing aqueous xalalka, soo saarida koloriin, caustic soodhaha, iyo electrolyzing milixda si ay u soo saaraan alkali;Tusaale ahaan, taarikada anode graphite waxaa loo isticmaali karaa sida anodes-ka-qaadista ee korantada ee xalka milixda si loo soo saaro soodhaha caustic;
3. Taarikada anode graphite waxaa loo isticmaali karaa sida anodes-ka korantada ee warshadaha elektiroonigga ah, iyaga oo ka dhigaya wax ku habboon codsiyada kala duwan ee electroplating;Alaabta koronto ku dhejisay ka dhig mid siman, jilicsan, u adkaysta daxalka, dhalaal sare, oo aan si fudud midabkoodu u dhalan.
Waxaa jira laba nooc oo hababka electrolysis isticmaalaya graphite anodes, mid waa electrolysis xal aqueous, iyo kan kale waa electrolysis cusbo dhalaalay.Warshadaha chlor alkali, kuwaas oo soo saara soodhaha caustic iyo gaaska koloriin by electrolysis of xal aqueous cusbo, waa isticmaale weyn ee garaafyada anodes.Intaa waxaa dheer, waxaa jira unugyo elektrolytic ah oo isticmaala milix dhalaalaysa si ay u soo saaraan biraha fudud sida magnesium, sodium, tantalum, iyo biraha kale, iyo graphite anodes ayaa sidoo kale loo isticmaalaa.
Saxan graphite anode waxa uu isticmaalaa sifada conductivity garaafyada.Dabeecadda, oo ka mid ah macdanta aan biraha ahayn, walxaha graphite waa walxo aad u sarreeya, iyo conductivity graphite waa mid ka mid ah walxaha wanaagsan ee wanaagsan.Iyadoo la isticmaalayo conductivity ee graphite iyo caabbinta aysiidh iyo alkali, waxa loo isticmaalaa sidii saxan conductive for taangiyada electroplating, magdhow daxalka ee biraha ee acid iyo alkali dhalaali.Sidaa darteed, walxaha graphite waxaa loo isticmaalaa sidii saxan anode ah.
Muddo dheer, unugyada korantada iyo unugyada diaphragm ee elektrolytka labaduba waxay isticmaaleen anodes graphite.Inta lagu jiro hawlgalka unugga korantada, graphite anode si tartiib tartiib ah ayaa loo isticmaali doonaa.Unugga korantada wuxuu cunaa 4-6 kg oo garaafiye anode ah halkii ton oo soodhaha caustic ah, halka unugga korantada ee diaphragm uu isticmaalo qiyaastii 6kg oo garaafiye anode ah halkii ton oo soodhaha caustic ah.Sida anode graphite uu noqdo mid khafiif ah oo masaafada u dhaxaysa cathode iyo anode korodho, tamarta unugga ayaa si tartiib tartiib ah u kordheysa.Sidaa darteed, ka dib wakhtiga qalliinka, waxaa lagama maarmaan ah in la joojiyo taangiga oo la beddelo anode.
