Iindaba

Igolide ibisoloko inomtsalane eluntwini kangangeenkulungwane, kungekuphela nje ngenxa yexabiso layo elingaphakathi, kodwa kwanangenxa yokukhanya kwayo okumangalisayo. Nokuba kukwizinto zokuhombisa, iingqekembe okanye ukusetyenziswa kwemizi-mveliso, ukukhanya kwegolide kubonisa iimpawu zayo ezikhethekileyo. Nangona kunjalo, ukufumana ukukhanya okugqibeleleyo kufuna okungaphezulu kokupholishwa; Ngokuqhelekileyo kubandakanya iinkqubo eziphambili zesinyithi.Isithando somlilo sokunyibilikisa i-Induction(VIM) yenye yeenkqubo ezinjalo edlala indima ebalulekileyo ekucoceni igolide, iphucula ubuhle bayo kunye neempawu zayo zokusebenza. Kweli nqaku, siza kujonga indlela yokwenza igolide ikhazimle, kunye nendima ebalulekileyoIsithando somlilo sokunyibilikisa i-Inductionidlala kule nkqubo.

Funda ngegolide kunye neempawu zayo

Igolide sisinyithi esixabisekileyo esaziwa ngokuxhathisa kwayo ukugqwala nokubola. Ulwakhiwo lwayo lweathomu luyivumela ukuba ibonakalise ukukhanya kakuhle, nto leyo eyinika ukukhazimla kwayo okuphawulekayo. Nangona kunjalo, ubunyulu begolide bunokwahluka, kwaye ukungcola kunokwenza buthathaka ukukhazimla kwayo. Igolide ecocekileyo (oko kukuthi igolide engama-24 karat) ithambile kwaye iyanyibilika, nto leyo eyenza ukuba ingafaneleki kangako kwizinto zokuhombisa zemihla ngemihla. Ke ngoko, igolide idla ngokuxuba nezinye izinyithi ezifana nobhedu, isilivere, okanye i-palladium ukuze yomeleze ukuqina kwayo ngelixa igcina ukukhazimla kwayo.

Ukubaluleka Kobunyulu Begolide

Ukukhazimla kwegolide kunxulumene ngqo nobunyulu bayo. Ukungcola akuchaphazeli nje kuphela umbala kunye nokukhazimla kwegolide, kodwa kunye nomgangatho wayo ngokubanzi. Umzekelo, ukubakho kobhedu kunokwenza igolide ibe nombala obomvu, ngelixa isilivere inokuyenza ibe nombala omhlophe. Ukuze bafumane umbala kunye nokukhazimla okufunekayo, abenzi begolide badla ngokufuna ukucoca igolide ukuya kwinqanaba eliphezulu lobunyulu. Kulapho keIsithando somlilo sokunyibilikisa i-Inductioniyasebenza.

Yintoni iIsithando somlilo sokunyibilikisa i-Induction?

Isithando somlilo sokunyibilikisa i-Induction(VIM) yinkqubo entsonkothileyo ye-metallurgical esetyenziselwa ukunyibilikisa nokucoca iintsimbi kwindawo elawulwayo. Le nkqubo ibandakanya ukubeka isinyithi kwi-crucible kunye nokuyifudumeza kusetyenziswa i-induction coil. Lonke olu sebenzi lwenzeka kwigumbi le-vacuum, elithintela ungcoliseko lomoya kwaye linciphise i-oxidation. Le ndlela iluncedo ngakumbi kwiintsimbi ezixabisekileyo ezifana negolide, njengoko ivumela ulawulo oluchanekileyo lwenkqubo yokunyibilikisa kunye nokwakheka kwemveliso yokugqibela.

Isithando somlilo sokunyibilikisa i-Inductioninkqubo

UkulungiselelaInyathelo lokuqala kwiVIM kukulungiselela igolide kunye nazo naziphi na iintsimbi ze-alloy. Izinto ezisetyenzisiweyo zilinganiswa ngononophelo kwaye zicocwe ukuze kususwe naziphi na izinto ezingcolisayo kumphezulu.

Ukunyibilika: Faka isinyithi esilungisiweyo kwisikruseli uze usibeke ngaphakathi kwikhoyili yokungenisa. Ukufudumala kokungenisa kudala intsimi ye-electromagnetic enyibilikisa isinyithi ngokukhawuleza nangokulinganayo.

Indawo yoVutha iVacuum: Amagumbi okucoca umoya enzelwe ukususa umoya kunye nezinye iigesi ezinokusabela kwisinyithi esinyibilikisiweyo. Le ndawo ibalulekile ekugcineni ubunyulu begolide kunye nokuthintela i-oxidation.

Ukudibanisa: Ukuba igolide iza kuxutywa nezinye iintsimbi, oku kwenziwa ngexesha lenkqubo yokunyibilika. Ulawulo oluchanekileyo lweemeko zobushushu kunye ne-vacuum luvumela ukuxubana ngokuchanekileyo kweentsimbi, nto leyo ephumela kwi-alloy efanayo.

Ukuphosa: Nje ukuba igolide inyibilikisiwe kwaye ifikelele kumxube ofunekayo, igalelwa kwiimolds ukuze kwenziwe ii-ingots zegolide okanye ezinye iimilo. Inkqubo yokupholisa ikwalawulwa ukuqinisekisa ukuthembeka kwemveliso yokugqibela.

UkugqibaEmva kokuphoswa, igolide ingadlula kwiinkqubo ezongezelelweyo ezifana nokuqhoboshelwa, ukupolishwa, kunye nokugqunywa nge-electroplating ukuze ikhanyise kwaye ilungiselelwe ubucwebe okanye ezinye izinto.

Iingenelo zokunyibilikisa igolide nge-vacuum induction

1. Yandisa ubunyulu

Enye yezona nzuzo ziphambili zeVIM kukukwazi kwayo ukuvelisa igolide ecocekileyo kakhulu. Indawo yokufunxa inkunkuma inciphisa umngcipheko wongcoliseko, iqinisekisa ukuba imveliso yokugqibela ayinazo izinto ezingafunekiyo. Oku kubaluleke kakhulu kwizicelo apho ubunyulu bubaluleke kakhulu, njengezixhobo ze-elektroniki okanye izixhobo zonyango.

2. Phucula iipropati zoomatshini

Inkqubo yokunyibilika nokupholisa elawulwayo kwiVIM iphucula iipropati zoomatshini zegolide. Ngokulawula ngononophelo inkqubo yokudibanisa, abavelisi banokwenza ii-alloys zegolide ezineempawu ezithile, ezinje ngamandla anyukileyo okanye ukuguquguquka okuphuculweyo, ngaphandle kokunciphisa ukukhazimla.

3. Umgangatho ozinzileyo

I-VIM ivumela ulawulo oluchanekileyo lweenkqubo zokunyibilikisa nokudibanisa, nto leyo ekhokelela kumgangatho ohambelanayo ukusuka kwibhetshi ukuya kwibhetshi. Oku kubalulekile kubavelisi abafuna ukuhambelana kwemveliso, nokuba kukusetyenziswa kwezinto zokuhombisa okanye kwimizi-mveliso.

4. Nciphisa i-oxidation

Indawo yokufunxa umoya kwi-VIM inciphisa kakhulu umngcipheko we-oxidation ngexesha lenkqubo yokunyibilika. Oku kubaluleke kakhulu kwigolide, njengoko i-oxidation inokubangela ukutshintsha kombala kunye nokulahleka kokukhazimla. Ngokunciphisa ukudibana neoksijini, i-VIM inceda ukugcina iimpawu zobuhle begolide.

5. Ukuguquguquka kwezinto

I-VIM ayipheleli kwigolide kuphela; ingasetyenziselwa ukunyibilikisa nokucokisa iintlobo ngeentlobo zeesinyithi. Olu tshintsho lwenza ukuba ibe lukhetho olunomtsalane kubavelisi abasebenza ngezinto ezahlukeneyo kwaye bafuna inkqubo yokunyibilikisa ethembekileyo.

Indlela yokwenza igolide likhazimle

NgelixaIsithando somlilo sokunyibilikisa i-InductionIdlala indima ebalulekileyo ekucoceni igolide, iindlela ezahlukeneyo zokugqiba ziyafuneka ukuze kufezekiswe ukukhazimla okugqibeleleyo. Nazi ezinye iindlela zokwenza igolide ikhanye:

1. Ukupolisha

Ukupolisha yenye yezona ndlela ziqhelekileyo zokuphucula ukukhazimla kwegolide. Le nkqubo ibandakanya ukusebenzisa izinto ezirhabaxa ukususa iziphene kumphezulu kunye nokudala umphezulu ogudileyo nokhanyayo. Abenzi bezinto zokuhombisa badla ngokusebenzisa izinto zokupolisha kunye namavili okubutha ukuze bafumane ukukhazimla okuphezulu.

2. Ukucoca

Ngaphambi kokupolisha, igolide kufuneka icocwe ukuze kususwe ukungcola, ioyile, okanye ukubola. Ungasebenzisa isisombululo esithambileyo samanzi afudumeleyo kunye nesepha ethambileyo, uze uhlambe uze womise ngelaphu elithambileyo.

3. Ukufakelwa kwe-electroplating

Kwezinye iindlela zokusebenza, ukugquma igolide kunokuphucula ukukhazimla kunye nokubonakala kwezinto zegolide. Le nkqubo ibandakanya ukugquma isiseko sesinyithi ngomaleko obhityileyo wegolide, okubonelela ngokugqitywa okukhazimlayo ngelixa kunciphisa iindleko.

4. I-Rhodium plating

I-Rhodium plating yindlela ethandwayo esetyenziselwa ukonyusa ukukhazimla kwegolide emhlophe. I-Rhodium yintsimbi ekhanyayo kakhulu enika ukugqitywa okukhanyayo, okufana nesipili. Le nkqubo ayiphuculi nje kuphela ukukhanya kodwa ikwanceda ukhuselo kwimikrwelo kunye nokutshintsha kombala.

5. Ukugcinwa rhoqo

Ukuze igolide ihlale ikhazimla, kubalulekile ukuyigcina icocekile rhoqo. Oku kuquka ukucoca nokupolisha njengoko kufuneka, kunye nokugcina izinto zegolide ngendlela efanelekileyo ukuthintela ukukrweleka nokonakala.

ukuququmbela

Ubuhle begolide abuxhomekekanga kwixabiso layo kuphela kodwa nakwimbonakalo yayo emangalisayo. Ukuze ufumane ukukhanya okugqibeleleyo kufuneka kudityaniswe ubunyulu obuphezulu kunye neendlela zokugqiba ezisebenzayo.Isithando somlilo sokunyibilikisa i-Inductionidlala indima ebalulekileyo ekucocweni kwegolide, iqinisekisa ukuba ifikelela kumanqanaba obunyulu afunekayo kunye nomgangatho. Ngokuqonda ukubaluleka kweVIM kunye nokusebenzisa iindlela ezifanelekileyo zokunyamekela, nabani na unokunandipha ukuqaqamba kwegolide kangangeminyaka ezayo. Nokuba kukwizinto zokuhombisa, izixhobo ze-elektroniki okanye ezinye iindlela, ukukhazimla kwegolide bekusoloko kuluphawu lobuhle kunye nokugqwesa, okufezekiswa ngeenkqubo eziphambili zesinyithi.
