U dir sooji

Daxalka {{0} saxan garaafka u adkaysta waa nooc ka mid ah walxaha garaafka leh ee iska caabbinta daxalka aad u fiican. Saxan garaafka daahirnimada sare leh ayaa iska caabin heersare ah leh sababtoo ah nadiifintiisa sare iyo wax yar oo wasakh ah.

Sifada

1. Iska caabbinta daxalka xooggan: waxay u dulqaadan kartaa inta badan asiidhka, alkalis iyo dareerayaasha organic, gaar ahaan heerkulka sare iyo deegaanka daxalka xooggan.

2. conductivity wanaagsan: saxan graphite leeyahay conductivity wanaagsan, waxaa loo isticmaali karaa in la sameeyo electrodes iyo qaybaha kale ee korontada, conductivity waxaa lagu hagaajin karaa by daahirsanaanta graphite.

3. Iska caabin heerkul sare ah: heerkulka shaqadu wuxuu gaari karaa 400 darajo -3000 digrii, waxayna ilaalin kartaa waxqabadka xasilloon ee jawiga heerkulka sare iyada oo aan cillad ama dhaawac.

4. Si fudud loo farsameeyo: saxan garaafeed waa sahlan tahay in la gooyo, rogo, shiiddo iyo hawlo habayn kale, kaas oo dabooli kara baahiyaha qaabab iyo cabbiro kala duwan, laakiin way jajaban tahay oo waxay u baahan tahay inay saameyn ku yeelato-.

Goobaha codsiga

1. Warshadaha kiimikaad: Warshadaha petrochemical, taarikada graphite waxa inta badan loo isticmaalaa daxal ahaan{1} walxaha adkaysi u leh si loo soo saaro weelasha, tuubooyinka iyo qalabka si ay isaga caabiyaan nabaad guurka warbaahinta daxalka ah.

2. Hydrometallurgy: Habka hydrometallurgy, taarikada graphite waxaa loo isticmaali karaa in lagu soo saaro foornada foornada, crucibles iyo qaybaha kale si ay ugu adkeystaan heerkulka sare iyo deegaanka daxalka.

3. Warshadaha Korantada: Hantida korantada ee saxanka garaafka ayaa ka dhigaysa in loo isticmaali karo in lagu soo saaro electrodes, burushyada iyo qaybaha kale ee korantada, kuwaas oo leh codsi ballaaran oo warshadaha korontada.

4. Goobo kale: saxan garaafka waxa kale oo loo isticmaali karaa in lagu sameeyo alaabta xidhidhiyaha, xidho{1} alaabaha adkaysta iyo saliidaha, iwm

Qoraallada Isticmaalka

1. Avoid oxidation: high temperature>Hawo 400 darajo ah way fududahay in la oksijiso, ilaalinta gaaska aan shaqayn ayaa loo baahan yahay.

2. Ka-hortagga -saamaynta makaanikada: naqshadaynta kaydinta ayaa loo baahan yahay inta lagu jiro rakibidda si looga hortago burburka geesaha iyo dildilaaca.

3. Dayactirka joogtada ah: da'da lakabka resinka waa in lagu hubiyo saxanka garaafka ee uurka leh, lakabka resinka waa in dib loo rinjiyeeyaa wakhtiga.

Daxalka{0}Taariko garaafka adkaysi u leh waxay leeyihiin sifooyin aad u wanaagsan oo kala duwan waxaana si balaadhan looga isticmaalaa meelo badan. Fahamka noocyadooda, sifooyinkooda, goobaha codsiga iyo hababka dayactirka ayaa kaa caawin kara inay si fiican u ciyaaraan doorka taarikada garaafyada oo ay kordhiyaan noloshooda adeeg.
