Goobaha codsiga ee budada garaafka iyo budada garaafka macmalka ah

Budada Graphite waxay leedahay sifooyin aad u fiican, sidaas darteed waxaa si weyn loogu isticmaalaa biraha, mishiinada, korontada, kiimikada, dharka, difaaca qaranka iyo qaybaha kale ee warshadaha. Goobaha codsiga ee budada garaafyada dabiiciga ah iyo budada garaafiga macmalka ah waxay leeyihiin qaybo isku dhafan iyo kala duwanaansho labadaba. Tifaftiraha garaafka Furuite ee soo socda wuxuu soo bandhigayaa goobaha codsiga ee budada garaafka iyo budada garaafka macmalka ah.

1. Warshadaha biraha

Warshadaha birta ah, budada garaafyada dabiiciga ah waxaa loo isticmaali karaa in lagu soo saaro walxaha dib-u-celinta sida lebenka-magnesia-carbon iyo lebenka aluminium-carbon sababtoo ah caabbinta oksaydhka wanaagsan. Budada garaafiga macmalka ah waxaa loo isticmaali karaa sidii birta samaynta electrode, laakiin electrodes ka samaysan budada graphite dabiiciga ah way adag tahay in loo isticmaalo foornooyinka korontada ee birta samaynta leh xaaladaha adag ee shaqada.

2. Warshadaha mishiinada

Warshadaha mishiinada, agabka garaafyada waxaa inta badan loo isticmaalaa sidii qalab u adkaysta iyo saliidaynta. Walaxda ceeriin ee bilowga ah ee loogu talagalay diyaarinta garaafyada la fidin karo waa graphite flake-carbon-sare, iyo reagents kale oo kiimiko ah sida sulfuric acid (ka sarreeya 98%), hydrogen peroxide (ka sarreeya 28%), potassium permanganate, iwm waa dhammaan heerka warshadaha. reagents. Tallaabooyinka guud ee diyaargarowga waa sida soo socota: heerkul ku habboon, qaybaha kala duwan ee xalalka hydrogen peroxide, graphite flake dabiiciga ah iyo sulfuric acid xoog leh ayaa lagu daraa habab kala duwan, waxay falceliyaan wakhti go'an oo hoos yimaada walaaq joogto ah, ka dibna biyo lagu dhaqo ilaa dhexdhexaad ah, iyo xarun dhexe. fuuqbaxa ka dib, faakuum-ku-qallajiyey 60 °C. Budada garaafiga dabiiciga ah waxay leedahay sifeyn wanaagsan waxaana badanaa loo isticmaalaa wax lagu daro saliidaha. Qalabka loogu talagalay gudbinta dhexdhexaadka ah waxay si ballaaran u adeegsadaan faraantiga piston-ka, xirmooyinka xirida iyo xirmooyinka laga sameeyay budada garaafiga macmalka ah, uma baahna inay ku daraan saliidda saliidda inta lagu jiro hawlgalka. Budada graphite-ka dabiiciga ah iyo alaabta isku dhafan ee resin polymer ayaa sidoo kale loo isticmaali karaa meelaha kor ku xusan, laakiin caabbinta xirashada uma fiicna sida budada garaafka macmalka ah.

3. Warshadaha kiimikada

Budada garaafka macmalka ah waxay leedahay sifooyinka caabbinta daxalka, kulaylka wanaagsan ee wanaagsan iyo qulqulka hooseeya. Waxaa si weyn loogu isticmaalaa warshadaha kiimikada si loo sameeyo kulaylka beddelayaasha, taangiyada falcelinta, munaaradaha nuugista, filtarrada iyo qalabka kale. Budada graphite-ka dabiiciga ah iyo alaabta isku dhafan ee resin polymer ayaa sidoo kale loo isticmaali karaa beeraha kor ku xusan, laakiin kuleylka kuleylka iyo caabbinta daxalka uma fiicna sida budada garaafka macmalka ah.

Iyadoo horumarinta joogtada ah ee tiknoolajiyada cilmi-baarista, rajada codsiga ee budada graphite ee macmalka ah waa mid aan la qiyaasi karin. Waqtigan xaadirka ah, horumarinta alaabta garaafyada macmalka ah ee dabiiciga ah ee dabiiciga ah sida alaabta ceeriin waa mid ka mid ah siyaabaha muhiimka ah ee lagu ballaariyo goobta codsiga ee garaafyada dabiiciga ah. Budada graphite ee dabiiciga ah sida alaabta ceeriin ee caawimada ah ayaa loo isticmaalay wax soo saarka qaar ka mid ah budada garaafka macmalka ah, laakiin horumarinta alaabta garaafyada macmalka ah ee budada garaafiga dabiiciga ah sida alaabta ceeriin ee ugu weyn kuma filna. Waa habka ugu wanaagsan ee lagu gaari karo yoolkan adigoo si buuxda u fahmaya oo isticmaalaya qaabka iyo sifooyinka budada garaafyada dabiiciga ah, iyo qaadashada hababka ku habboon, waddooyinka iyo hababka si loo soo saaro alaabooyinka garaafyada macmalka ah ee leh qaab gaar ah, guryaha iyo isticmaalka.
