Grafayithi ngokuyinyibilikisa
Izixhobo eziluncedo zeNingheda
Izinto ze-1 zeGraphite zinobuninzi obuphezulu kunye ne-porosity ephantsi, ephikisana nokukhukuliseka kwe-aluminium etyhidiweyo kunye ne-gaseous aluminium particles.
2.Izinto eziluhlaza ezicocekileyo ezinokucoceka okuphezulu, umxholo ophantsi we-ash kuthintela izinto ezinokuveliswa kwimveliso, kuthintelwe amabala, imingxunya kwifilimu eyenziwe ngealuminium, enokuqinisekisa umgangatho wefilimu eyenziwe ngealuminium.
I-3.Graphite crucible ineempawu ezichanekileyo, umphezulu ogudileyo, ukuxhathisa okunamandla, ukusetyenziswa kancinci kunye nobomi benkonzo ende.

Izinto eziluncedo ze grafayithi ngokuyinyibilikisa for vacuum ngumphunga ukutyabeka kwealuminium
1. Ukuzinza kweThermal: Ngokweemeko zokusetyenziswa kwegraphite ye-crucible yokufudumeza nokupholisa ngokukhawuleza, uyilo olukhethekileyo lwenziwa ukuqinisekisa ukuthembeka komgangatho;
2.Umelana nokumelana: Uyilo olufanayo kunye nolwakhiwo lwematrikhi olulibazisayo ukubola komhlwa;
3. Ukuchasana kwempembelelo: Amandla okothuka e-thermal anokuthi amelane ne-graphite crucible anokumelana kakhulu, ke nayiphi na inkqubo inokwenziwa ngokuzithemba;
4. Ukuchasana ne-Acid: ukongezwa kwezinto ezizodwa eziphucula kakhulu umgangatho wee-crucibles ze-graphite, inentsebenzo egqwesileyo ngokubhekiselele kwizikhombisi zokumelana ne-asidi, kwaye iyolula kakhulu ubomi benkonzo ye-graphite crucibles;
5. Ukuqhuba okuphezulu kwe-thermal: Umxholo ophezulu wekhabhoni uqinisekisa ukuqhuba kakuhle kwe-thermal, kunciphisa ixesha lokunyibilika, kwaye kunciphisa ngokubonakalayo ukusetyenziswa kwepetroli okanye ukusetyenziswa kwamandla;
6.Ukulawulwa kongcoliseko lwesinyithi: Ulawulo olungqongqo lwezinto ezibonakalayo luqinisekisa ukuba i-graphite crucible ayingcolisi isinyithi ngexesha lokuchithwa;
7. Uzinzo lomgangatho: Inkqubo yobugcisa kunye nenkqubo yokuqinisekisa umgangatho wendlela yoxinzelelo oluphezulu yokuqinisekisa uzinzo lomgangatho.
