Kumashishini ahlukeneyo, kukho ukungaqondi kakuhle okuxhaphakileyo malunga nosetyenziso lwei-graphite crucible.Abantu abaninzi ngempazamo bakholelwa ukuba ezi mveliso zinokubaluleka okuncinci kwimarike, becinga ukuba azibalulekanga.Nangona kunjalo, le mbono ayinakuba kude nenyaniso.Ngelixa ii-graphite crucibles zinokubonakala zinolwakhiwo olulula - oluyilelwe ukuba luqulathe ulwelo olwahlukeneyo - ukungabikho kwazo kunokukhokelela kwimiba ebalulekileyo kumacandelo omabini esinyithi kunye neekhemikhali.Makhe sihlolisise iingenelo ze-graphite crucibles kwaye sihlolisise usetyenziso lwazo ezahlukeneyo.
1. Ukuguquguquka kunye nokomelela
Enye yeengenelo ezibalaseleyo zokukrolwa kwegraphite kukuguquguquka kwazo.Ezi zityhuthutyhulo ngokuyinhloko zenziwe ngegraphite kunye ne-quartz, ezixutywe kunye neentlobo ezahlukeneyo zeekhemikhali kwaye emva koko zixhomekeke ekutshisweni kobushushu obuphezulu kwimveliso yazo.Olu qulunqo olukhethekileyo lwenza ukuba ii-graphite crucibles zimelane ne-acidic eninzi, i-alkaline, kunye ne-corrosive liquids, ibenze baxabiseke kakhulu kwishishini lemichiza.Uvavanyo olubanzi ngoososayensi luye lwabonisa ukuba i-aqua regia - umxube onobungozi kakhulu we-acids - inokugcinwa ngokukhuselekileyo ngaphakathi kwee-graphite crucibles.
Ngaphezu koko, iicrucibles zegraphite zibonisa ukumelana nobushushu obumangalisayo, obukwaziyo ukumelana namaqondo obushushu angaphezu kwama-5000 degrees Celsius ngaphandle kokuthotywa okukhulu.Oku kuzenza zilungele ukuqulatha intsimbi enyibilikisiweyo, ialuminiyam, kunye nezinye iintsimbi nakwimo yazo engamanzi, iqinisekisa kwakhona ukusetyenziswa kwazo kumashishini ahlukeneyo.
2. Umgangatho ongayekeleliyo
Umgangatho we-graphite crucibles yenye inzuzo ebalulekileyo.Ezi crucibles ziyilelwe ukuba zimelane noxinzelelo olukhulu lwangaphandle, zizenza zixhathise kakhulu izoyikiso ngaphandle kokuba ziphantsi kwamandla angaphaya kwamandla azo.Inkqubo yokuvelisa i-graphite crucible nganye ibambelela kwimigangatho engqongqo, iqinisekisa ukucaca kwinqanaba ngalinye.Kuphela ngale ndlela yobuchule apho imveliso yokugqibela inokuthi ithathwe njengefanele injongo.
I-graphite crucible nganye ivavanywa ngokuqatha phambi kokuba ifumaneke kubathengi.Izigqeba ezilawulayo ziqhuba uhlolo olungenamkhethe kwezi mveliso, kwaye naziphi na iimeko zokungathotyelwa kwemigaqo zinokukhokelela ekumisweni kwemveliso kunye nezohlwayo ezinkulu, okanye nokuvalwa kwendawo yokuvelisa.Amanyathelo angqongqo akhona ngenxa yokwenzakala okunokuthi kubangele imixholo evuzayo kwimpilo yabantu.Ukuthintela ukuvuza okunjalo kufuna ukuba kusonjululwe lo mba kwingcambu yawo, kuqalwa ngokuveliswa kwezi ntsimbi.
