Iindaba

Igolide ibisoloko ithandeka eluntwini kangangeenkulungwane, kungekuphela nje ngenxa yexabiso layo elingaphakathi, kodwa nangenxa yokubengezela nokubengezela kwayo okumangalisayo. Nokuba kukwizacholo, kwiingqekembe zemali okanye kwishishini, ubukhazikhazi begolide bungqina iimpawu zayo ezizodwa. Nangona kunjalo, ukufumana ukukhanya okugqibeleleyo kufuna okungakumbi kunokupolisha; Ngokuqhelekileyo kubandakanya iinkqubo eziphambili ze-metallurgical.I-Induction Melting Furnace(VIM) yenye inkqubo enjalo edlala indima ebalulekileyo ekusulungekiseni igolide, iphucula ubuhle bayo kunye neempawu zayo zokusebenza. Kweli nqaku, siza kujonga indlela yokwenza igolide ibengezele, kunye nendima ebalulekileyoI-Induction Melting Furnaceidlala kwinkqubo.

Funda ngegolide kunye neempawu zayo

Igolide yintsimbi exabisekileyo eyaziwa ngokuxhathisa ukubola kunye nokonakala. Ukwakheka kwayo kweathom kuyivumela ukuba ibonakalise ukukhanya kakuhle, inika uphawu lwayo lokubengezela. Noko ke, ukusulungeka kwegolide kunokwahluka, yaye ukungcola kunokukwenza buthathaka ukubengezela kwayo. Igolide esulungekileyo (okt 24 karat gold) ithambile kwaye iyanyibilika, iyenza ingalungeli kakhulu ukusetyenziswa kwezacholo zemihla ngemihla. Ke ngoko, igolide ihlala idityaniswa nezinye iintsimbi ezinje ngobhedu, isilivere, okanye i-palladium ukukhulisa ukuqina kwayo ngelixa igcina ukukhazimla kwayo.

Ukubaluleka kobunyulu beGolide

Ukubengezela kwegolide kunxulumene ngokuthe ngqo nobunyulu bayo. Ukungcola akuchaphazeli kuphela umbala kunye nokukhanya kwegolide, kodwa kunye nomgangatho wayo jikelele. Ngokomzekelo, ubukho bobhedu bunokwenza igolide ibe nombala obomvu, ngelixa isilivere inokuyinika umbala omhlophe. Ukuze bafumane umbala onqwenelekayo nokubengezela, abakhandi begolide ngokufuthi bafuna ukusulungekisa igolide ngomlinganiselo ophakamileyo wokusulungeka. KulaphoI-Induction Melting Furnaceuyadlala.

Yintoni iI-Induction Melting Furnace?

I-Induction Melting Furnace(VIM) yinkqubo entsonkothileyo yesinyithi esetyenziselwa ukunyibilika kunye nokucokisa iintsimbi kwindawo elawulwayo. Inkqubo ibandakanya ukubeka isinyithi kwi-crucible kunye nokufudumala usebenzisa i-coil induction. Umsebenzi wonke wenziwa kwigumbi le-vacuum, elithintela ukungcoliseka kwe-atmospheric kunye nokunciphisa i-oxidation. Le ndlela inenzuzo ngokukhethekileyo kwiintsimbi ezixabisekileyo ezifana negolide, njengoko ivumela ulawulo oluchanekileyo lwenkqubo yokunyibilika kunye nokubunjwa kwemveliso yokugqibela.

I-Induction Melting Furnaceinkqubo

Ukulungiselela: Isinyathelo sokuqala kwi-VIM kukulungiselela igolide kunye nayiphi na isinyithi se-alloy. Izinto ezisetyenziswayo zilinganiswe ngononophelo kwaye zicocwe ukuze kususwe nakuphi na ukungcoliseka komhlaba.

Ukunyibilika: Beka isinyithi esilungisiweyo kwi-crucible kwaye uyibeke ngaphakathi kwi-coil induction. Ukufudumeza kwe-induction kudala indawo ye-electromagnetic enyibilikisa isinyithi ngokukhawuleza nangokulinganayo.

Imo engqongileyo yeVacuum: Amagumbi okufunxa adalwe ukuphelisa umoya kunye nezinye iigesi ezinokusabela ngesinyithi esinyibilikisiweyo. Lo mmandla ubalulekile ekugcineni ubunyulu begolide kunye nokuthintela i-oxidation.

I-alloying: Ukuba igolide iza kuxutywa nezinye iintsimbi, oku kwenziwa ngexesha lokunyibilika. Ukulawulwa ngokuchanekileyo kweqondo lokushisa kunye neemeko ze-vacuum zivumela ukuxuba okuchanekileyo kweentsimbi, okubangelwa i-alloy homogeneous.

Iyaphosa: Yakube igolide inyibilikiswa yaza yafikelela kwindawo oyifunayo, igalelwa kwimibumbo ukuze yenze iingots zegolide okanye ezinye iimilo. Inkqubo yokupholisa iphinda ilawuleke ukuqinisekisa ukuthembeka kwemveliso yokugqibela.

Ukugqiba: Emva kokuphoswa, igolide inokungena kwiinkqubo ezongezelelekileyo ezinje ngokuthambisa, ukupolisha, kunye ne-electroplating ukukhulisa ukukhazimla kwayo nokuyilungiselela ubucwebe okanye ezinye izinto ezisetyenziswayo.

Izibonelelo zokuNyibilika kweGolide yeVacuum Induction

1. Ukuphucula ubunyulu

Enye yeenzuzo eziphambili ze-VIM kukukwazi ukuvelisa igolide ecocekileyo. Ubume bevacuum bunciphisa umngcipheko wongcoliseko, ukuqinisekisa ukuba imveliso yokugqibela ayinazinto ezingafunwayo. Oku kubaluleke kakhulu kwizicelo apho ucoceko lubaluleke kakhulu, njengombane okanye izixhobo zonyango.

2. Ukuphucula iimpawu zoomatshini

Inkqubo elawulwayo yokunyibilika kunye nokupholisa kwi-VIM iphucula iimpawu zomatshini zegolide. Ngokulawula ngokucophelela inkqubo yokudibanisa, abavelisi banokwenza ii-alloys zegolide kunye neempawu ezithile, ezifana nokunyuka kwamandla okanye ukuphuculwa kwe-ductility, ngaphandle kokubingelela i-luster.

3. Umgangatho ozinzileyo

I-VIM yenza ulawulo oluchanekileyo lweenkqubo zokunyibilika kunye ne-alloying, okubangela umgangatho ohambelanayo ukusuka kwibhetshi ukuya kwibhetshi. Oku kubalulekile kubavelisi abafuna ukuguquguquka kwemveliso, nokuba yeyobucwebe okanye usetyenziso lweshishini.

4. Nciphisa i-oxidation

Ubume be-vacuum ye-VIM bunciphisa kakhulu umngcipheko we-oxidation ngexesha lenkqubo yokunyibilika. Oku kubaluleke ngakumbi ngegolide, njengoko i-oxidation inokubangela ukuguquka kombala kunye nokulahleka kwe-luster. Ngokunciphisa ukunxibelelana neoksijini, i-VIM inceda ukugcina iimpawu zobuhle begolide.

5. Ukuguquguquka

I-VIM ayiphelelanga kwigolide; ingasetyenziselwa ukunyibilika kunye nokucokisa iintlobo ngeentlobo zesinyithi. Oku kuguquguquka kwenza kube yinto ekhangayo kubavelisi abasebenza ngezinto ezahlukeneyo kwaye bafuna inkqubo ethembekileyo yokunyibilika.

Indlela yokwenza igolide ibengezele

NgelixaI-Induction Melting Furnaceidlala indima ebalulekileyo ekusulungekiseni igolide, iindlela ezahlukeneyo zokugqiba ziyafuneka ukufezekisa ukukhanya okugqibeleleyo. Nazi iindlela zokwenza igolide ibengezele:

1. Ukugudisa

Ukupholisha yenye yeendlela eziqhelekileyo zokuphucula ukubengezela kwegolide. Inkqubo ibandakanya ukusebenzisa izinto ezinqabileyo zokususa ukungapheleli kwendawo kunye nokudala indawo epholileyo, ebonakalisayo. Amatye anqabileyo ahlala esebenzisa iikhompawundi zokupolisha kunye namavili abhubhileyo ukuze afumane ukukhanya okuphezulu.

2. Ukucoca

Ngaphambi kokupholisha, igolide kufuneka icocwe ukususa ukungcola, i-oyile okanye ibala. Ungasebenzisa isisombululo esithambileyo samanzi afudumeleyo kunye nesepha ethambileyo, uze uhlambulule kwaye womise ngelaphu elithambileyo.

3.Electroplating

Kwezinye izicelo, ukufakwa kwegolide kunokunyusa ukukhazimla kunye nokubonakala kwezinto zegolide. Inkqubo ibandakanya ukugquma isiseko sesinyithi esinomqolo obhityileyo wegolide, ukubonelela ngesiphelo esicwebezelayo ngelixa sinciphisa iindleko.

4. I-Rhodium plating

I-Rhodium plating yindlela ethandwayo esetyenziselwa ukomeleza ukukhazimla kwegolide emhlophe. I-Rhodium yintsimbi ekhangayo kakhulu enika ukugqiba okuqaqambileyo, okufana nesipili. Le nkqubo ayiphuculi nje kuphela ukukhanya kodwa yongeza umaleko wokhuseleko kwimikrwelo kunye nokutshintsha kwebala.

5. Ukugcinwa rhoqo

Ukugcina igolide imenyezela, ukugcinwa rhoqo kubalulekile. Oku kubandakanya ukucoca kunye nokupolisha njengoko kufuneka, kunye nokugcinwa ngokufanelekileyo kwezinto zegolide ukukhusela imikrwelo kunye nomonakalo.

ukuququmbela

Umtsalane wegolide abukho nje kuphela kwixabiso layo kodwa kwanakubuhle bayo obumangalisayo. Ukufezekisa i-gloss egqibeleleyo kufuna ukudibanisa ukucoceka okuphezulu kunye neendlela ezisebenzayo zokugqiba.I-Induction Melting Furnaceidlala indima ephambili ekusulungekisweni kwegolide, iqinisekisa ukuba ifikelela kubunyulu obufunekayo kunye namanqanaba omgangatho. Ngokuqonda ukubaluleka kwe-VIM kunye nokusebenzisa iindlela ezifanelekileyo zokunyamekela, nabani na unokuyonwabela ubuqaqawuli begolide kwiminyaka ezayo. Nokuba kukwizacholo, kwizinto zombane okanye kwezinye izinto, ukubengezela kwegolide bekusoloko kuluphawu lobuhle nokugqwesa, okuphunyezwa ngeenkqubo eziphucukileyo zesinyithi.
