1. Warshadaha biraha
Warshadaha birta, budada garaafyada dabiiciga ah waxaa loo isticmaali karaa in lagu soo saaro walxaha dib-u-celinta sida leben kaarboonka magnesium iyo leben kaarboon aluminium sababtoo ah caabbinta oksaydhka ee wanaagsan. Budada garaafiga macmalka ah ayaa loo isticmaali karaa sidii electrode ee birta samaynta, laakiin electrode ka samaysan budada garaafiga dabiiciga ah way adag tahay in loo isticmaalo foornada korontada ee birta samaynta.
2. Warshadaha mishiinada
Warshadaha farsamada, alaabta garaafyada waxaa badanaa loo isticmaalaa sida dharka-iska-caabbinta iyo saliidaynta. Walaxda ceeriin ee bilowga ah ee loogu talagalay diyaarinta garaafyada la fidin karo waa garaafyada kaarboonka sareeyo, iyo reagents kale oo kiimiko ah sida sulfuric acid (ka sarreeya 98%), hydrogen peroxide (ka sarreeya 28%), potassium permanganate iyo reagents kale oo warshadeed ayaa la isticmaalaa. Tallaabooyinka guud ee diyaarinta waa sida soo socota: heerkulka ku habboon, saamiga kala duwan ee xal hydrogen peroxide, graphite flake dabiiciga ah iyo sulfuric acid xoog leh ayaa lagu daraa habraacyo kala duwan, oo ay ka falceliyaan waqti go'an ka hoos kicin joogto ah, ka dibna loo dhaqo si dhexdhexaad ah, kala soocidda centrifugal. fuuqbaxa iyo faakuum qallajinta at 60 ℃. Budada garaafiga dabiiciga ah waxay leedahay sifeyn wanaagsan waxaana badanaa loo isticmaalaa wax lagu daro saliidda. Si aad u gudbiso dhexdhexaadinta daxalka ah, giraangiraha piston-ka, siddooyinka xirida iyo xirmooyinka ka samaysan budada garaafiga macmalka ah ayaa si weyn loo isticmaalaa, iyada oo aan lagu darin saliidda saliidda marka la shaqeynayo. Budada garaafyada dabiiciga ah iyo isku-dhafka polymer resin ayaa sidoo kale loo isticmaali karaa meelaha kor ku xusan, laakiin caabbinta xirashada uma fiicna sida budada garaafka macmalka ah.
3. Warshadaha kiimikada
Budada garaafiga macmalka ah waxay leedahay sifooyinka caabbinta daxalka, conductivity kaamerada wanaagsan, permeability hoose, iyo waxaa si weyn loo isticmaalaa in warshadaha kiimikada si ay u sameeyaan kulaylka, taangiga falcelinta, munaaradda nuugista, filter iyo qalab kale. Budada graphite ee dabiiciga ah iyo qalabka isku dhafan ee polymer resin ayaa sidoo kale loo isticmaali karaa beeraha kor ku xusan, laakiin kuleylka kulaylka, caabbinta daxalka uma fiicna sida budada garaafka macmalka ah.
Iyadoo horumarinta tignoolajiyada cilmi-baarista, rajada codsiga ee budada garaafyada macmalka ah waa mid aan la qiyaasi karin. Waqtigan xaadirka ah, isticmaalka garaafyada dabiiciga ah sida alaabta ceeriin si loo horumariyo alaabta garaafyada macmalka ah waxaa loo tixgelin karaa mid ka mid ah siyaabaha muhiimka ah ee lagu ballaariyo goobta codsiga ee garaafyada dabiiciga ah. Budada graphite ee dabiiciga ah ayaa loo isticmaalay sidii qalab cayriin ah oo caawiya wax soo saarka qaar ka mid ah budada garaafyada macmalka ah, laakiin kuma filna in la horumariyo alaabta garaafyada macmalka ah ee budada garaafiga dabiiciga ah sida alaabta ugu muhiimsan. Habka ugu wanaagsan ee lagu xaqiijin karo yoolkan waa in si buuxda loo isticmaalo qaabka iyo sifooyinka budada garaafyada dabiiciga ah, iyo in la soo saaro alaabooyinka graphite ee macmalka ah oo leh qaab-dhismeed gaar ah, waxqabadka iyo isticmaalka tiknoolajiyada ku habboon, waddada iyo habka.
