7. Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo)
Q1: Kutheni ii-isostatic graphite crucibles zingcono kunee-extruded graphite crucibles?
I-graphite ye-isostatic idityaniswe kusetyenziswa uxinzelelo lwe-isotropic hydrostatic, nto leyo enika iipropati ezifanayo zesakhiwo (umlinganiselo we-isotropy 1.05–1.25). I-graphite ekhutshiweyo inendawo yokulungelelanisa i-grain, nto leyo ekhokelela ekwandeni kobushushu obungalinganiyo kunye nokuqhekeka ngexesha loxinzelelo lobushushu.
Umbuzo 2: I-graphite oxidation iqala xa iphantsi kobushushu obungakanani?
Kwindawo evulekileyo equlethe ioksijini, igrafiti iqala ukunyibilikisa ioksijini malunga nama-400 °C. Kwindawo engenanto okanye enegesi engasebenziyo (iArgon/Nitrogen), igrafiti yeVET Energy ecocekileyo kakhulu imelana namaqondo obushushu afikelela kuma-2760 °C.
Umbuzo 3: Umxholo wothuthu uchaphazela njani ukucocwa kwesinyithi esixabisekileyo?
Uthuthu lumele ukungcola kwezinto ezisisiseko (umz., uFe, uAl, uSi). Xa amaqondo obushushu ephezulu, oku kungcola kusasazeka kube yigolide enyibilikisiweyo okanye isilivere, okutshintsha ubunono kunye nokukhazimla. I-VET Energy's ≤ 5 ppm ultra-pure grade isusa iingozi zokungcola.
Umbuzo 4: Ngaba i-VET Energy ingabonelela ngejometri ezenziwe ngokwezifiso kunye neengubo ezikhethekileyo?
Ewe. Senza iijometri ezenziwe ngokwezifiso, izigqubuthelo ezinemisonto, kunye noyilo olunemingxuma emininzi, olune-CVD Silicon Carbide (SiC) coatings ukuze kuphuculwe ukumelana nokuguguleka, ukukhuselwa kwe-oxidation, kunye nokungasebenzi kakuhle kweekhemikhali.
