China China Glass Ng'anjo ya Silika Njerwa kuchokera ku Real Factory fakitale ndi opanga | Rongsheng

Kufotokozera Kwachidule:

Silika carbite njerwa ndi mtundu wa mankhwala refractory kuti amapangidwa makamaka ndi pakachitsulo carbide, silika carbide njerwa ntchito SiC monga chuma chachikulu, zomwe zikuphatikizapo 72% ~ 99% SiC okhutira. njerwa ya kaboni ya silicon imapangidwa ndi kusakaniza SiC granule, SiC ufa ndi womangira kudzera mu ukalamba kusakaniza, kuumba, kuyanika ndi kuwombera. silicon carbide block ili ndi mawonekedwe apamwamba matenthedwe matenthedwe, kukana kwamphamvu kwambiri ndipo imatha kugwiritsidwa ntchito ngati zomangira za aluminiyamu cell. Njerwa ya silicon carbon refractory imakhala yofunika kwambiri popanga zitsulo, komanso makampani opanga zitsulo zopanda chitsulo.

Silicate carbon njerwa ndi wa ndale refractory, amene kupirira kukokoloka kwa asidi ndi alkali slags, solvents, ndi dzimbiri mankhwala ena. Silicon carbide ili ndi zilembo zamphamvu kwambiri, kukana kwa anti-oxidation, ndipo palibe kusintha pa kutentha kwakukulu. Muzopangira zonse za njerwa zopanda oxide refractory, njerwa ya slilica carbon ndiyo yotsika mtengo kwambiri komanso yogwiritsidwa ntchito kwambiri pamalo ena. zomwe zingagwiritsidwe ntchito m'mafakitale osiyanasiyana, monga mafakitale a miyala, mafakitale a galasi, mafakitale azitsulo, mafakitale osindikizira, ndi mafakitale opepuka. Kupatula apo, njerwa ya silika ya kaboni yogulitsa imakhala ndi ntchito yabwino kwambiri yolimbana ndi kukokoloka koyipa kwa chilengedwe, monga kutentha kwapamwamba kwambiri, kukana kwa abrasive, kukana kwakukulu kwamafuta, kugonjetsedwa ndi asidi ndi kukokoloka kwa alkali slag ndi koyefifi ya kutentha kochepa ndi etc.

Katundu wa Silica Carbide Njerwa

Mphamvu zazikulu,
Kutentha kwakukulu kwa conductivity,
Kukana bwino kwa abrasive,
Kukana kwakukulu kwa kutentha kwa kutentha,
Kukana kukokoloka kwabwino kwambiri,
Kulimbana mwamphamvu ndi kukokoloka kwa asidi ndi alkali slag,
.Kuchepetsa kutentha kowonjezera kutentha.

Kupangidwa kwa Silica Carbide Njerwa

Silicate carbide block zida zopangira ndi silicon carbide, pafupifupi 72% -99%. Silicon carbide imatchedwanso moissanite, corundum sand kapena refractory sand. zomwe zimapangidwa ndi mchenga wa quartz, petroleum coke kapena malasha phula, ndi matabwa amatabwa, omwe amapangidwa ndi kutentha kwakukulu kusungunuka mu ng'anjo yamagetsi yamagetsi.

Njira Yopangira Njerwa ya Silica Carbide

Njerwa za silicon carbide zimapangidwa kuchokera ku silicon carbide, zopangira zomwe zimapangidwira mung'anjo yamagetsi yolimbana ndi kutentha kwa 2500 ° C, chifukwa cha silika ndi kaboni. Njerwa za silika za kaboni zimakhala ndi matenthedwe opangira matenthedwe kakhumi kuposa a fireclay refractories, corrosion yabwino komanso kukana kugwedezeka kwamafuta, ndipo amatha kupangidwa kukhala mawonekedwe ovuta. Njerwa ya kabati ya silika imatha kupirira kuukira kwa slag komanso kukokoloka kwa moto.

Silica Carbide Njerwa Gulu

Njerwa za Silicon carbide refractory zitha kugawidwa kukhala njerwa zadongo zomangika za silicon carbide, njerwa za Si3N4 zomangika za silicon carbide, njerwa za Sialon zomangika za silicon carbide, njerwa za β-SiC zomangika za silicon carbide, njerwa za Si2ON2 zomangika za silicon carbide ndi njerwa za recrystal silicon carbide.

Kugwiritsa ntchito njerwa ya Silica Carbide

Njerwa ya silika carbide imakhala ndi matenthedwe apamwamba kwambiri, kukana kwabwino, kukana kugwedezeka kwamafuta komanso kukana kwa dzimbiri. Chifukwa chake silika carbon brick ili ndi ntchito zosiyanasiyana motere:
