Budada Graphite waxay leedahay sifooyin badan oo aad u fiican, sidaa darteed waxaa si weyn loogu isticmaalaa birta, mishiinada, korontada, kiimikada, dharka, difaaca qaranka iyo qaybaha kale ee warshadaha. Meelaha loo adeegsado budada graphite dabiiciga ah iyo budada graphite macmalka ah waxay leeyihiin qaybo is dulsaaran iyo kala duwanaansho. Tifaftiraha graphite ee Furuite ee soo socda wuxuu soo bandhigayaa goobaha loo adeegsado budada graphite iyo budada graphite macmalka ah.
1. Warshadaha Birta
Warshadaha birta, budada garaafiga dabiiciga ah waxaa loo isticmaali karaa in lagu soo saaro agabyo iska caabiya sida lebenka magnesia-kaarboon iyo lebenka aluminium-kaarboon sababtoo ah iska caabbinta oksaydheynta wanaagsan. Budada garaafiga macmalka ah waxaa loo isticmaali karaa elektroodh sameynta birta, laakiin elektroodhyada laga sameeyay budada garaafiga dabiiciga ah way adag tahay in loo isticmaalo foornooyinka korontada ee sameeya birta oo leh xaalado shaqo oo adag.
2. Warshadaha Mashiinka
Warshadaha mashiinnada, agabka garaafitka waxaa badanaa loo isticmaalaa sidii walxo u adkaysta xirashada iyo saliidaynta. Agabka ceeriin ee ugu horreeya ee loogu talagalay diyaarinta garaafitka la ballaarin karo waa garaafitka la ballaariyo ee kaarboon-ka badan, iyo walxaha kale ee kiimikada sida aashitada sulfuric ee xooggan (ka sarreeya 98%), hydrogen peroxide (ka sarreeya 28%), potassium permanganate, iwm. dhammaantood waa walxo warshadeed oo heer warshadeed ah. Tallaabooyinka guud ee diyaarinta waa sidan soo socota: heerkul ku habboon, saamiyo kala duwan oo ah xalka hydrogen peroxide, garaafitka dabiiciga ah ee flake iyo aashitada sulfuric ee xooggan ayaa lagu daraa habab kala duwan, waxaa la falgalaa muddo cayiman iyadoo si joogto ah loo walaaqayo, ka dibna waxaa lagu dhaqayaa biyo ilaa dhexdhexaad ah, oo la centrifuge gareeyay. Ka dib fuuq-baxa, waxaa lagu qalajiyey faakiyuum 60 °C. Budada garaafitka dabiiciga ah waxay leedahay saliid wanaagsan waxaana badanaa loo isticmaalaa sidii lagu daro saliidaynta. Qalabka loogu talagalay gudbinta dhexdhexaadka daxalka ah wuxuu si weyn u isticmaalaa giraangiraha piston, giraangiraha shaabadaynta iyo biinanka laga sameeyay budada garaafitka macmalka ah, mana u baahna in lagu daro saliid saliidayn ah inta lagu jiro hawlgalka. Alaabada isku-dhafka ah ee budada graphite dabiiciga ah iyo walxaha polymer resin ayaa sidoo kale loo isticmaali karaa meelaha kor ku xusan, laakiin iska caabbinta xirashada ma fiicna sida budada graphite ee macmalka ah.
3. Warshadaha kiimikada
Budada graphite-ka ee macmalka ah waxay leedahay astaamo u adkeysiga daxalka, hab-dhaqanka kulaylka wanaagsan iyo awood-siinta oo hooseysa. Waxaa si weyn loogu isticmaalaa warshadaha kiimikada si loo sameeyo beddelayaasha kulaylka, haamaha falcelinta, munaaradaha nuugista, shaandheeyayaasha iyo qalab kale. Agabka isku-dhafka ah ee budada graphite dabiiciga ah iyo polymer resin ayaa sidoo kale loo isticmaali karaa meelaha kor ku xusan, laakiin hab-dhaqanka kulaylka iyo iska caabbinta daxalka ma aha kuwo wanaagsan sida kuwa budada graphite-ka macmalka ah.
Iyadoo la horumarinayo tignoolajiyada cilmi-baarista ee joogtada ah, rajada codsiga ee budada graphite-ka macmalka ah waa mid aan la qiyaasi karin. Waqtigan xaadirka ah, horumarinta alaabada graphite-ka macmalka ah oo leh graphite-ka dabiiciga ah oo ah walxo cayriin ah waa mid ka mid ah siyaabaha muhiimka ah ee lagu ballaarin karo goobta codsiga ee graphite-ka dabiiciga ah. Budada graphite-ka dabiiciga ah oo ah walxo cayriin ah oo kaabayaal ah ayaa loo isticmaalay soo saarista qaar ka mid ah budada graphite-ka macmalka ah, laakiin horumarinta alaabada graphite-ka macmalka ah oo leh budada graphite-ka dabiiciga ah oo ah walxaha cayriin ee ugu muhiimsan kuma filna. Waa habka ugu wanaagsan ee lagu gaari karo yoolkan iyadoo si buuxda loo fahmayo loona adeegsanayo qaab-dhismeedka iyo astaamaha budada graphite-ka dabiiciga ah, iyo qaadashada hababka, waddooyinka iyo hababka ku habboon si loo soo saaro alaabada graphite-ka macmalka ah oo leh qaab-dhismeed gaar ah, sifooyin iyo isticmaal.
