Eyona lab idale idayimani amakhonkco othethathethwano DEF Umbala
Iidayimani ezikhule kwiLab, kwelinye icala, ziluphindaphindo oluchanekileyo lwedayimani zendalo kwaye ziyenziwa emva koko zithengiswe kwakhona ngoninzi lwababoneleli bedayimani “kwi-intanethi”.Aba baboneleli basebenza njenge "brokers" phakathi korhwebo kunye nawe umthengi, ngaphandle kokutyalomali kwiidayimani ngokwazo.

I-HPHT CVD ilebhu yamadoda ekhulile idayimani amakhonkco 1 carat 2 carat
iidayimani Lab-ekhule ngokwemichiza, optically, kwaye ngokwasemzimbeni efanayo iidayimani kwembiwa, ekhule ngaphantsi komhlaba-ukubeka phakathi amatye anqabileyo kakhulu ezinqwenelekayo kwaye ibhiyozelwa.La matye anqabileyo angaqhelekanga kwaye akhethekileyo adalwe ukuba abe nombala ofanayo kunye nokucaca njengedayimani ephezulu esembiweyo.

VS VVS ilebhu yesiko ekhulile amakhonkco edayimani yokuzibandakanya Ngexabiso eliphantsi
Idayimani ekhuliswe ilebhu kule mihla yenziwa kusetyenziswa iindlela ezimbini - iCVD kunye neHPHT.Indalo epheleleyo idla ngokuthatha ngaphantsi kwenyanga.Kwelinye icala, indalo yedayimane yendalo phantsi koqweqwe loMhlaba ithatha iibhiliyoni zeminyaka.
Indlela ye-HPHT isebenzisa enye yezi nkqubo zintathu zokuvelisa - i-belt press, i-cubic press kunye ne-split-sphere press.Ezi nkqubo zintathu zinokudala uxinzelelo oluphezulu kunye nobushushu obungqongileyo apho idayimani inokuphuhlisa khona.Iqala ngembewu yedayimani efakwa kwikhabhoni.Idayimani ke ityhileke kwi-1500°Celsius kwaye icinezelwe ukuya kwi-1.5 pounds per square intshi.Ekugqibeleni, ikhabhoni iyanyibilika kwaye idayimani yelebhu yenziwa.
I-CVD isebenzisa iqhekeza elicekethekileyo lembewu yedayimane, edla ngokudalwa kusetyenziswa indlela ye-HPHT.Idayimani ibekwe kwigumbi elishushu ukuya kutsho kuma-800°C elizaliswe yigesi ezele yicarbon, efana neMethane.Emva koko iigesi zi-ionize zibe yiplasma.Ikhabhoni ecocekileyo evela kwiigesi ibambelela kwidayimane kwaye icwecwe.

Brilliant Sika elebhu efikelelekayo amakhonkco edayimani akhule athengiswa
Idayimani ekhule kwiLab, ekwabizwa ngokuba ziidayimani ezidalwe elebhu, ziidayimani ezikhuliswe ngaphakathi kwindawo yelabhoratri zisebenzisa itekhnoloji ephucukileyo yokusika ephindaphinda iimeko zendalo apho idayimani yokwenyani iphuhla phantsi komhlaba.Ngenxa yoko, iidayimani ezikhuliswe elebhu zibonisa iimpawu ezifanayo zomzimba, zamehlo kunye neekhemikhali.Ngenxa yoko, iidayimani ezikhule kwilebhu zithathwa njengeidayimani zokwenyani, ngokungafaniyo nezifanisi zedayimani kunye needayimani zokwenziwa, ezinje ngecubic zirconia okanye i-moissanite.Ezo azifani ngokubonakalayo nangekhemikhali kwiidayimani ezembiweyo, kwaye zithengisa ngamaxabiso aphantsi kakhulu kunedayimani ezikhuliswe elebhu.
