Sharaxaada faahfaahsan ee Isticmaalka Alaabta Garaafka

Isticmaalka alaabooyinka garaafyada ayaa aad uga sarreeya sidii aan filaynay, haddaba waa maxay isticmaalka alaabta garaafyada ee aan hadda naqaanno?

1,Loo isticmaalo sida walxo kaaliyaha

Marka la dhalaalayo birta daawaha kala duwan, ferroalloys, ama soo saarida calcium carbide (calcium carbide) iyo fosfooraska jaalaha ah iyadoo la isticmaalayo foornada arc korantada ama foornada arc hoose, qulqul xoog leh ayaa lagu soo bandhigaa aagga dhalaalay ee foornada korantada iyada oo loo marayo electrodes (ama is dubarid joogto ah). Electrodes - ie koollada elektiroonigga ah) ama electrodes graphitized si loo dhaliyo qaanso, u beddela tamarta korantada tamar kulayl, iyo kor u qaadista heerkulka ilaa 2000 darajo Celsius, taas oo buuxinaysa shuruudaha dhalaalidda ama falcelinta. Birta magnesium, aluminium, iyo sodium waxaa guud ahaan soo saara korantada cusbada dhalaalaysa. Waqtigan xaadirka ah, qalabka korantada anode ee unugga elektiroonigga ah waa dhammaan electrodes graphite ama electrodes-ka is dubitaanka joogtada ah (koollada anode, mararka qaarkood anode la dubay). Heerkulka korantada milixda dhalaalaysa ayaa guud ahaan ka hooseeya 1000 darajo Celsius. Qalabka korantada ee loo isticmaalo unugyada milixda dareeraha elektiroonigga ah ee soo saarista soodhaha caustic (sodium hydroxide) iyo gaaska chlorine guud ahaan waa anodes graphitized. Qalabka korantada ee madaxa foornada ee foornada iska caabbinta ee loo isticmaalo soo saarista carbide silicon waxay sidoo kale isticmaashaa electrodes graphitized. Marka lagu daro ujeedooyinka kor ku xusan, alaabta kaarboon iyo graphite ayaa si ballaaran loogu isticmaalaa sida qalabka wax soo saarka ee warshadaha wax soo saarka sida giraangiraha iyo burushyada. Intaa waxaa dheer, waxaa sidoo kale loo isticmaalaa sidii ulaha kaarboon ee baytariyada qallalan, ulaha kaarboonka iftiinka ee nalalka raadinta ama iftiinka arc, iyo anodes ee hagaajinta meerkuriyada.

2,Loo isticmaalo sida walxo refractory

Iyada oo ay ugu wacan tahay awoodda kaarboonka iyo alaabada graphite si ay ugu adkeystaan ​​heerkulka sare oo ay leeyihiin awood heerkul sare oo wanaagsan iyo iska caabbinta daxalka, dahaar badan oo foornada birta ah ayaa lagu dhisi karaa blocks kaarboon, sida hoose, feeraha, iyo caloosha foornooyinka dhalada birta, dahaarka foornooyinka ferroalloy iyo foornooyinka kalsiyum carbide, iyo hoose iyo dhinacyada unugyada electrolytic aluminium. Qalabyo badan oo loo isticmaalo dhalaalinta biraha qaaliga ah iyo kuwa dhifka ah, iyo sidoo kale qolofyada garaafyada ee loo isticmaalo dhalaalidda dhalada quartz, ayaa sidoo kale laga sameeyay biibiile garaafaysan. Alaabooyinka kaarboon iyo graphite ee loo isticmaalo agabka refractory guud ahaan waa in aan loo isticmaalin jawi oksijiinta ah. Sababtoo ah kaarboonka ama graphite waxay si dhakhso ah u burburaan heerkulka sare ee jawiga oksaydhka.

Qaybaha foornada Vacuum

3,Loo isticmaalo sidii qalab dhismeed u adkaysta daxalka

Electrodes-garafaysan ee lagu shubay resins organic ama inorganic waxay leeyihiin sifooyin caabbinta daxalka wanaagsan, kulaylka wanaagsan, iyo xajinta hoose. Noocan garaafiga uurka ku jira waxaa sidoo kale loo yaqaan garaafka aan la taaban karin. Waxaa si weyn loo isticmaalaa soo saarista kulaylka kala duwan, taangiyada falcelinta, kondensers, munaaradaha gubashada, munaaradaha nuugista, qaboojiyaha, kuleyliyaha, filtarrada, bambooyin, iyo qalab kale. Waxaa si weyn loogu isticmaalaa qaybaha warshadaha sida sifaynta batroolka, petrochemical, hydrometallurgy, acid iyo alkali wax soo saarka, fiilooyinka synthetic, waraaqaha, iyo badbaadin kara waxyaabo badan oo biraha ah sida birta. Wax soo saarka garaafka aan la taaban karin ayaa noqday laan muhiim ah oo ka mid ah warshadaha kaarboonka.

Doonta marada graphite

4,Loo isticmaalo sidii wax xidhashada u adkaysta iyo saliidaynta

Maaddooyinka kaarboon iyo graphite kaliya maaha inay leeyihiin xasillooni kiimiko oo sarreeya, laakiin sidoo kale waxay leeyihiin sifooyin sifeyn wanaagsan. Inta badan waa wax aan macquul aheyn in la hagaajiyo caabbinta xirashada ee qaybaha silbashada iyadoo la isticmaalayo saliidda saliidda ee hoos yimaada xawaaraha sare, heerkulka sare, iyo xaaladaha cadaadiska sare. Alaabta u adkaysata garaafyada waxay ku shaqayn karaan iyada oo aan saliid lagu shubin warbaahinta daxalaysa heerkulka u dhexeeya -200 ilaa 2000 darajo Celsius iyo xawaare sareeyo (ilaa 100 mitir/second). Sidaa darteed, kombaresarada iyo bambooyin badan oo qaada warbaahinta xunxun ayaa si weyn u isticmaala faraantiyada piston-ka, siddooyinka xidhida, iyo biraha ka samaysan walxaha garaafka. Uma baahna in lagu daro saliidaha inta lagu jiro hawlgalka. Maaddadan xirashada u adkeysaneysa waxaa lagu sameeyaa kaarboonka caadiga ah ama walxaha garaafka ah ee leh xabagta organic ama birta dareeraha ah. Emulsion graphite sidoo kale waa saliid wanaagsan oo loogu talagalay farsamaynta biraha badan (sida sawirista siliga iyo sawirida tuubada).

5,Sida heerkul sare oo bir ah iyo walxo ultrapure ah

Qalabka qaab dhismeedka ee loo isticmaalo wax soo saarka, sida dhalooyinka koritaanka crystal, weelasha sifaynta gobolka, biraha, qalabyada, kuleyliyaha induction, iwm, dhammaan waxaa laga soo shaqeeyay qalabka garaafyada sare-nadiifinta. Looxyada dahaarka graphite iyo saldhigyada loo isticmaalo dhalaalinta faakuumka, iyo sidoo kale qaybaha ay ka midka yihiin tuubooyinka foornada iska caabbinta heerkulka sare, ulo, taarikada, iyo shabagyada, ayaa sidoo kale laga sameeyay walxaha garaafka. wax badan ka arag www.futmetal.com
