Yadda za a zaɓi kayan ƙuntatawa don masu ƙona shara?

Masu ƙonawa na yau da kullun sun haɗa da ƙona ƙungiyoyi, ƙona ƙoshin wuta, tsarin ƙonawa na CAO, masu ƙona gado mai jujjuyawa, da masu ƙona wutar makera. Kayan ƙyama don masu ƙona shara suna da halaye masu zuwa:

StabilityDaɗin kwanciyar hankali mai kyau;

② Kyakkyawan ƙarfin zafin zafin jiki da sa juriya;

Resistance Kyakkyawan juriya na acid;

Karfafa kwanciyar hankali;

Resistance Kyakkyawan juriya na lalata (CO, Cl2, SO2, HCl, tururin ƙarfe alkali, da sauransu);

Kyakkyawan gini (mara tsari);

Kyawawan zafi da rufin zafi.

Abubuwan ƙonawa daban -daban, sassa daban -daban na amfani, da yanayin zafin aiki daban -daban, shawarwarin zaɓin masu zuwa don tunani ne kawai:

Zazzabi mai aiki na rufin, bangon gefen da mai ƙona ɗakin ƙonewa shine 1000-1400 ℃, ana iya amfani da manyan tubalin alumina da tubalin yumɓu tare da raguwar 1750-1790 ℃, kuma robobi tare da raguwar 1750-1790 ℃ iya kuma a yi amfani. .

Ana amfani da babba, tsakiya, da ƙananan ɓangarorin ginshiƙi a zazzabi na 1000-1200 ° C, ana iya amfani da tubalin carbide na silicon ko tubalin yumɓu tare da raguwar 1710-1750 ° C, kuma ana iya amfani da katanga masu jurewa. amfani;
