Isicelo

IGreen Silicon Carbide iveliswa ngokufudumeza isanti ye-silica kunye nomthombo wekhabhoni, oqhele ukuba yi-petroleum coke, ukuya kumaqondo obushushu aphezulu kwisithando esikhulu. Isiphumo sale nkqubo yobushushu obuphezulu kukwenziwa kwekristale yeenkozo zeSilicon Carbide. Iipowder ze-silicon carbide ezikumgangatho ophezulu, ezihlelwe ngamanzi zilinganiswe ngokwemigangatho echanekileyo.

Umgubo we-silicon carbide eluhlaza sisixhobo esiqinileyo nesirhabaxayo esisasazwa ngokulinganayo ngobukhulu bezinto ezincinci. Ubunzima baso bulandela idayimani kunye ne-B4C kuphela, kwaye sinzima kune-silicon carbide emnyama. Ngoko ke kufanelekile ukugaya uluhlu olukhulu lwezinto ezinzima ezifana ne-titanium alloy, imabula, i-carbide alloy, iiglasi ezibonakalayo, iiseramikhi, njl.njl.

Kwelinye icala, i-silicon carbide eluhlaza ineempawu ezingaqhelekanga ezifana nokuzinza okuphezulu kweekhemikhali, izinga eliphantsi lokukhula kobushushu, ifanelekile kwiingubo zokumelana nobushushu kunye nokugqwala, iipeyinti, kunye nezinye iimveliso zokwakha.

Iimbonakalo

1.uxinano oluphezulu

2.ukwanda okuphantsi kobushushu, ukumelana okuphezulu kwe-oxidation

3.ukumelana kweekhemikhali okugqwesileyo

4.ukumelana okukhulu kobushushu

5.ukumelana nokuguguleka okuphezulu kunye nobunzima

6.amandla aphezulu, ukumelana nobushushu obuphezulu

7. Amandla obushushu aphezulu
