Igrafu esithe tyabazizixhobo ezisetyenzisiweyo ngokubanzi kwizixhobo zokunyibilikisa kunye nokusetyenziswa kweqondo lobushushu. Zisetyenziselwa ukufudumeza izinyithi okanye ezinye izinto kumaqondo obushushu aphezulu zokunyibilika, ukuphosa, kunye nolunye usetyenziso oluphezulu. Nangona kunjalo, ekuhambeni kwexesha, ukungcola ezahlukeneyo kunye neentsali eziqokelele kumphezulu wendlela enqabileyo, echaphazela intsebenzo yayo. Ke ngoko, ukuqonda ukuba ucoceke njani ngokufanelekileyoI-greyitite crucabskubalulekile ukuba sandise ubomi babo ngenkonzo. Kweli nqaku, siza kwazisa amanyathelo aphambili ekucoceni igrafu.
Kutheni le nto kufuneka sicoceke igrafu?
I-greyitite crucabsUkusebenza kumaqondo obushushu aphezulu athambekele ekufundeni nasekufunxeni ukungcola okwahlukeneyo, kubandakanya intsalela yensimbi, i-oxide, kunye nezinye izinto ezingezizo ezingezizo. Ezi zinto zingcolileyo zinokubangela ungcoliseko kumphezulu we-on othe tye, ukunciphisa ukuqhubela phambili kwengqondo kunye nokuphumeza kwe-thermal. Ukongeza, ukungcola okuqokelelekileyo kunokubangela uxinzelelo lobushushu kwitheko elithe tye, ekugqibeleni kukhokelela ekuqhekezweni okanye ukonakala.
Ke ngoko, ukucocwa rhoqo kwegrafu yegraphite linyathelo eliphambili ekugcineni ukusebenza kwabo nokundisa ubomi babo ngenkonzo.
Amanyathelo aphambili okucoca i-phydite subles
Oku kulandelayo ngamanyathelo aphambili ekucoceni igrafu
1. Iimali zokhuseleko:
Ngaphambi kokucoca igrafiki entle, nceda uqiniseke ukuba kuthathwe amanyathelo afanelekileyo okhuseleko. Oku kubandakanya ukunxiba iigloves ezixhaphaza ubushushu kunye ne-goggles ukunqanda ukwenzakala.
2. Ukupholisa okunqabileyo:
Ngaphambi kokucoca, qinisekisa ukuba igrafu ebumbekile iphilile. Ukucocwa kwamaqondo obushushu aphezulu kunokubangela ukuba iqondo loyike kunye nomonakalo othe tyaba.
3. Susa iintsalela:
Sebenzisa i-scraper yensimbi okanye ipliers ukuba isuse kancinci nakuphi na intsalela kumphezulu we-thercable. Nceda usebenze ngononophelo ukunqanda ukukrazula itheleke.
4. Ukucoca iikhemikhali:
Abanye banzima ukususa ubumdaka kunye neentsalela, iiarhente zokucoca iikhemikhali zinokusetyenziswa. Khetha iarhente efanelekileyo yokucoca kwi-gratite cructibs, ezinje ngeSodium hydroxide okanye i-potassium hydroxide okanye i-potassium hydroxide, kwaye ulandele imiyalelo yokusebenzisa iarhente yokucoca. Ngokwesiqhelo, iarhente yokucoca inyibilikisiwe emanzini afudumeleyo kwaye inqabile ifakwe kuyo ukuthamba kwaye isuse ubumdaka. Emva kokugqitywa, hlamba imbeke kakhulu ngamanzi acocekileyo okuthintela intsalela yemichiza ukusuka kumphezulu.
5. Ukomisa imbethekile:
Emva kokucoca kunye nokuhleba, beka i-oveni eneqondo lobushushu okanye umoya owomileyo ngokwendalo ukuqinisekisa ukuba yomile ngokupheleleyo. Kulumkele ukusebenzisa ubukhali obukhali okanye iinkqubo zokupholisa ukuthintela uxinzelelo lwe-thermal.
I-6. Jonga umphezulu we-the the the the:
Emva kokucoca kunye nokomisa, jonga ngononophelo umhlaba othe tye ukuze uqiniseke ukuba akukho ntsalela okanye umonakalo. Ukuba kukho imfuneko, ukucoca okungaphezulu okanye ukulungiswa kunokwenziwa.
Ukuthatha amanyathelo okhuseleko kunye neengcebiso
Xa ukucoca igrafu, kukho ezinye iindlela zokuthatha amanyathelo athile kunye neengcebiso:
Kulumkele ukusebenzisa iiarhente zokucoca i-acidic njengoko zinokonakalisa izixhobo zegrafu.
Sukusebenzisa iibrashi zensimbi okanye iibhulukhwe zokucoca ukucoca ubunqamleza njengoko zinokukrazula umphezulu.
Xa usebenzisa iiarhente zokucoca iikhemikhali, nceda nxiba izixhobo zokhuselo kwaye uqinisekise ukuba ukusebenza kwenziwa kwindawo enomoya ovuthayo.
Rhoqo ucocekile ukunqaba ukuthintela ubumdaka kunye nentsalela ekuqokeleleni kwinqanaba ekunzima ukuyiphatha.
Ngokweemfuno zenkqubo yemveliso, ukhuseleko lokukhathalela okanye ukuphucula ukunganyangeki kwe-comrosion yemizobo enqabileyo kunokunyulwa.
Cukupakishwa
Ukucoca igrafitite igrafu linyathelo eliphambili ekugcineni ukusebenza kwabo nokundisa ubomi babo benkonzo. Ngokususa rhoqo ubumdaka kunye neentsalela, kunye nokulandela amanyathelo afanelekileyo okucoca, inokuqinisekiswa ukuba iinqaba ezinqatyisiweyo ziqhubeka nokusebenza kwizicelo zobushushu obungaphezulu. Kwimimandla yokunyibilikisa intsimbi kunye nokulungisa ubushushu obuphezulu, ukugcina ucoceko lwethumbe sisitshixo sokuqinisekisa ukuvelisa umgangatho okuphezulu.
