Horumarinta jiil cusub oo ah qalabka garaafka nadiifka ah ee sare

Garaafka nadiifka sareWaxa loola jeedaa graphite ka kooban kaarboon ka badan 99.99%. Garaafyada daahirsanaanta sare leh waxay leedahay faa'iidooyin sida iska caabin heerkul sare ah, iska caabin daxalka, caabbinta shoogga kulaylka, iskudhafka ballaarinta kulaylka hooseeya, is-saliimaynta, is-caabbinta iska caabbinta hooseeya, iyo farsamaynta farsamada fudud. Sameynta cilmi baarista habka wax soo saarka ee graphite-nadiifinta sare iyo hagaajinta tayada wax soo saarka ayaa muhiimad weyn u leh horumarinta warshadaha garaafyada sare ee nadiifka ah ee Shiinaha.

Si kor loogu qaado horumarinta warshadaha graphite-nadiifinta sare ee Shiinaha, shirkadeena waxay ku maalgelisay tiro badan oo shaqaale iyo ilo cilmi baarista iyo horumarinta garaafka sare ee daahirsanaanta, samaynta wax ku ool ah oo ku saabsan degaanka ee graphite-nadiifinta sare. Hadda aan kuu sheego wax ku saabsan cilmi baarista iyo guulaha horumarineed ee shirkadeena:

1. socodka guud ee soo saarida garaafka saafiga ah ee sare:

Habka ugu muhiimsan ee wax soo saarka garaafyada sare ee nadiifka ah ayaa lagu muujiyay sawirka 1. Waxaa cad in habka wax soo saarka ee garaafyada sare ee nadiifka ah uu ka duwan yahay kan electrodes graphite. Garaafka nadiifka ah ee sarreeya wuxuu u baahan yahay qalab cayriin ah oo isotropic ah, kaas oo u baahan in lagu geliyo budo yaryar. Tiknooloojiyada istaatishka ee istaatistikada waxay u baahan tahay in la isticmaalo, iyo wareegga dubista waa dheer yahay. Si loo gaaro cufnaanta la rabo, wareegyo duban oo impregnation ah ayaa loo baahan yahay, iyo wareegga garaafyada ayaa aad uga dheer garaafyada caadiga ah.

1.1 Qalabka ceeriin

Alaabta ceeriin ee lagu soo saaro garaafka saafiga ah ee sarreeya waxaa ka mid ah isku-darka, xirayaasha, iyo wakiilada impregnating. Isku darka inta badan waxaa laga sameeyaa kookaha batroolka ee irbadda iyo kookaha asphalt. Tani waa sababta oo ah kookaha batroolka ee qaabaysan irbada ayaa leh astaamo ay ka mid yihiin waxyaabaha ku jira dambaska hooseeya (guud ahaan in ka yar 1%), garaafaynta fudud ee heerkulka sare, dhaqdhaqaaqa wanaagsan iyo kulaylka kuleylka, iyo iskudubarid fidinta toosan oo hooseeya; Garaafyada lagu helo iyadoo la isticmaalayo kookaha asphalt isla heerkulka garaafyada ayaa leh iska caabin koronto oo sarreeya laakiin xoog farsamo oo sarreeya. Sidaa darteed, marka la soo saarayo badeecooyinka garaafyada, marka lagu daro kookarka batroolka, qayb ka mid ah coke asphalt ayaa sidoo kale loo isticmaalaa si loo hagaajiyo xoogga farsamada ee alaabta. Xirayaasha sida caadiga ah waxay isticmaalaan daamurka dhuxusha,taas oo ah wax soo saarka habka distillation ee daamurka dhuxusha. Waa adag madow oo heerkulka qolka ah mana laha meel dhalaalaysa oo go'an.

1.2 Calcination/Nadiifinta

Calcination waxaa loola jeedaa daawaynta kulaylka sare ee alaabta cayriin kaarboon adag ee kala duwan ee hoos yimaada xaaladaha hawada go'doonsan. Isku geynta la xushay waxay ka kooban yihiin heerar kala duwan oo qoyaan ah, wasakh, ama walxo aan kacsanayn oo ku jira qaab dhismeedka gudaha taas oo ay ugu wacan tahay kala duwanaanshaha heerkulka kolayga ama da'da juqraafiga ee samaynta dhuxusha. Maaddooyinkan waxay u baahan yihiin in horay loo sii tirtiro, haddii kale waxay saameyn doontaa tayada alaabta iyo waxqabadka. Sidaa darteed, isku darka la doortay waa in la dhalaaliyaa ama la nadiifiyaa.

1.3 Shiidasho

Qalabka adag ee loo isticmaalo wax soo saarka garaafyada, in kasta oo cabbirka xannibaadda la dhimay ka dib markii la nadiifiyo ama la nadiifiyo, weli waxay leeyihiin cabbir aad u weyn oo leh isbeddelo muhiim ah iyo halabuurka aan sinnayn. Sidaa darteed, waxaa lagama maarmaan ah in la burburiyo xajmiga guud ee qaybta si loo buuxiyo shuruudaha walxaha.

1.4 Isku qas iyo cajiin

Budada dhulka waxay u baahan tahay in lagu qaso daamurka dhuxusha inta aan la gelin ka hor inta aan la gelin mishiinka cajiinka kulaylka leh si loo hubiyo qaybinta alaabta.

1.5 Samaynta

Hababka ugu muhiimsan waxaa ka mid ah qaabaynta extrusion, qaabaynta, qaabaynta gariir, iyo qaabaynta istatic pressing.

1.6 Duubista

Alaabooyinka kaarboonka ee la sameeyay waa in ay maraan habka duban, kaas oo ku lug leh kaarboon-gaynta xidhaha kookaha iyada oo loo marayo daawaynta kulaylka (qiyaastii 1000 ℃) xaaladaha hawada ee go'doonsan.

1.7 Uurka

Ujeedada impregnation waa in la buuxiyo daloolada yaryar ee ka dhex abuurmay gudaha badeecada inta lagu guda jiro habka duban ee asfalt dhalaalaysa iyo wakiilada kale ee impregnating, iyo sidoo kale daloolada jira ee furan ee qaybaha kookaha wadar ahaan, si loo hagaajiyo cufnaanta mugga, conductivity, xoogga farsamada, iyo caabbinta daxalka kiimikada ee alaabta.

1.8 Garaafaynta

Garaafaynta waxaa loola jeedaa habka daawaynta kulaylka heerkulkiisu sarreeyo kaas oo u beddela kaarboon-garafeed ahaan aan degganayn oo kaarboon garaafka garaafka ah iyada oo loo marayo firfircoonida kulaylka.

Ku soo dhawoow inaad booqato oo aad kormeerto warshadeena, inta badan waxay ku hawlan tahay caaryada garaafka, garaafka saafiga ah ee sare, grafiit crucibles, nano graphite budada, garaafka cadaadiska isostatic, electrodes graphite, ulaha graphite, iyo wixii la mid ah.
