Chinhu chikuru chei silica brick

Iyo acidic refractory zvinhu zvinonyanya kuumbwa ne tridymite, cristobalite uye shoma shoma yasara quartz uye girazi chikamu.

Iyo silica yemukati iri pamusoro pe94%. Chokwadi density i2.35g/cm3. Iyo ine kurwisa kune acid slag erosion. Higher high tembiricha simba. Iyo yekutanga tembiricha yekunyorovesa mutoro ndeye 1620～1670℃. Izvo hazvizokanganise mushure mekushandiswa kwenguva refu pakupisa kwakanyanya. Low thermal shock stability (1 ~ 4 nguva dzekuchinjana kupisa mumvura) Sirica yechisikigo inoshandiswa seyakasvibirira, uye chiyero chakakodzera che mineralizer chinowedzerwa kukurudzira kutendeuka kwequartz mumuviri wakasvibira kuita phosphorite. Kudzikiswa zvishoma nezvishoma pa1350～1430℃ mukuderedza mamiriro ekunze. Kana yapiswa kusvika 1450 ℃, pachave neinenge 1.5 ~ 2.2% yehuwandu hwekuwedzera vhoriyamu. Uku kuwedzera kwasara kuchaita kuti majoini akachekwa akasimba uye ive nechokwadi chekuti masonry ane yakanaka mhepo kusimba uye kusimba kwechimiro.
