Umenzi (ifektri) yezitena zeSilicon Cabide, iipleyiti, iithayile
I-Silicon Carbide inyamezela uluhlu olubanzi lwee-asidi kunye ne-alkali. Kwaye ngokusebenza okugqwesileyo kokuqina okuphezulu, ubunzima obuphezulu, ukumelana nokunxiba okuphezulu, ukumelana nobushushu obuphezulu, ukuxhathisa umhlwa. Iindidi ezahlukeneyo zeemilo zamalungu akhethekileyo zilungele imigodi, i-petrochemical, i-metallurgical production, i-aerospace kunye nemizi-mveliso yenyukliya, njengendawo yokusingqongileyo ethile. Sinokwenza naziphi na iisayizi ezinikezelweyo ngokwesicelo somthengi.
Ukumelana nokunxiba, amandla obushushu obuphezulu kunye nokumelana nomhlwa kwenza i-Reaction Bonded SiC ibe yinto efanelekileyo yezinto ezinxitywayo, ezinje ngeentambo zombhobho, izitena, iithayile, iibhloko, njl.

ISilicon Carbide SiC (SiSiC/RBSiC) Iimpawu:
Ukukrazuka / ukuxhathisa ukonakala
Iimpawu ezigqwesileyo zokothuka kwe-thermal
Ukuxhathisa okugqwesileyo kwe-oxidation
Ulawulo olulungileyo lweemilo ezintsonkothileyo
I-conductivity ephezulu ye-thermal
Ukusebenza okuphuculweyo
Ubomi obude phakathi kokutshintshwa / ukwakha kwakhona
Ukuchasa ukubola
Ukumelana okuPhezulu kokunxiba
Amandla kwiqondo lobushushu eliphezulu ukuya kuthi ga kwi-1380°C
Ukusetyenziswa kweepleyiti zeSilicon carbide:
Ipleyiti ye-SiC ye-silicon ye-carbide kunye neethayile luhlobo lwepleyiti ekhethekileyo ye-ceramic esetyenziswa ngokubanzi kwimveliso emininzi yemizi-mveliso:
Ishishini leMigodi, iShishini loShishino, iShishini leMichiza, i-Crystallite Glass Industry, i-Magnetic Materials Industry, i-Metallurgy, i-Metallurgy Industry, i-Paper Industry, i-Petroleum Industry, i-kiln, njl.
Iimveliso ezenziwe ngokwezifiso ze-silicon carbide, imilo ekhoyo: iipleyiti, izitena, iithayile, ipleyiti yeradian, isikrufu, ipleyiti ecacileyo, umbhobho othe ngqo, imibhobho yeti, iringi, ingqiniba, isitshingitshane sekhowuni njalo njalo.
I-Shandong Zhongpeng Special Ceramics Co., Ltd yenye yezona zisombululo zikhulu ze-silicon carbide zeceramic ze-ceramic e-China. I-ceramic yobugcisa be-SiC: Ubulukhuni be-Moh yi-9 (ubulukhuni be-Moh entsha yi-13), kunye nokuchasana okugqwesileyo kukhukuliseko kunye nokugqwala, i-abrasion egqwesileyo - ukuxhathisa kunye ne-anti-oxidation. Ubomi benkonzo yemveliso ye-SiC yi-4 ukuya kwamaxesha ama-5 ubude ngaphezu kwe-92% yezinto ze-alumina. I-MOR ye-RBSiC yi-5 kumaxesha e-7 ye-SNBSC, ingasetyenziselwa imilo enzima ngakumbi. Inkqubo yekoteyishini ikhawuleza, ukuhanjiswa kuthenjisiwe kwaye umgangatho ungowesibini. Sihlala sizingisa ukucela umngeni kwiinjongo zethu kwaye sibuyisele iintliziyo zethu kuluntu.
