Mphamvu ya pakachitsulo carbide (SiC) pa katundu wa castables

⑴ Popeza SiC yokhayokha ndiyopanda madzi, sikophweka kunyowetsa, ndipo sikophweka kupanga filimu yamadzi, ndipo kumwa madzi otayika kumawonjezeka. Choncho, apamwamba a SiC okhutira, osauka workability ndi fluidity wa castable, ndi ozizira flexural mphamvu adzachepa.

⑵ Popeza kuchuluka kwa SiC (2.6 ~ 2.8g/cm3) ndikokulirapo kuposa kachulukidwe kazoumba (2.2 ~ 2.4g/cm3), kuchulukira kwa SiC, kumapangitsanso kuchuluka kwazinthuzo. Kutentha kumakwera ndipo zomwe zili mu SiC ndizokwera, kuchuluka kwa voliyumu kumawonjezeka pang’ono. Zomwe zili mu SiC zikuwonetsa phindu loyipa pakutengera kusintha kwa mzere wazinthu.

⑶ Zomwe zili mu SiC ndizopindulitsa ku mphamvu zoponyedwa, makamaka kutentha kwambiri (1100 ° C). Makamaka pamene SiC tinthu kukula ndi 150 mauna, sangathe kwathunthu oxidized, ndi mipata ena anapanga padziko SiC particles, amene bwino matenthedwe kukana mantha ndi mphamvu ya castable. SiC ya unoxidized imagwiranso ntchito ngati kulimbitsa tinthu.

⑷ Zokhala ndi SiC zochulukira, m’pamenenso zimatsutsana ndi khungu.

⑸ Kuchuluka kwa SiC, kumapangitsanso kukana kwa alkali.
