Abun da ke da tsayayya yana da wuya a kai ga yanayin yumburan yumbu a wannan zafin jiki, wanda ke da matukar tasiri ga aikin kayan aiki; Amfaninsodium hexametaphosphate a cikin refractory castable da fesa cika shi ne cewa yana da tsayayye da kyakkyawan ƙarfi mai ƙarfi da juriya da juriya mai zafi. Yana taimakawa wajen ƙarfafa tsarin haɗin kayan abu na kayan refractory, kuma yana iya yin foda ko granular refractory kayan haɗin gwiwa tare don nuna isasshen ƙarfi.

A cikin dogon lokaci na ci gaba da zagayawa da kayan aiki, shan tukunyar jirgi a matsayin misali, saboda da fluidized gudun konewa barbashi, da high zafin jiki yana da karfi yashwa da lalacewa sakamako a kan rufi refractory kayan, musamman tukunyar jirgi konewa jam'iyya da cyclone SEPARATOR. da sauran sassa karkashin lalacewa da thermal girgiza sakamako na barbashi, iska da kuma ƙura kafofin watsa labarai, sakamakon yashwa, lalacewa, peeling da rugujewar rufi na refractory. kayan aiki. Yana da matukar tasiri ga al'ada aiki da samar da tukunyar jirgi.

Sabili da haka, ya zama dole don haɓaka sabbin masu ɗaure tare da juriya mai zafi, juriya na lalata, juriya juriya da juriya na thermal don haɓaka aikin kayan haɓakawa.

Sodium hexametaphosphate yana da fa'idodi a cikin refractory castable da spray cika. Ta hanyar zaɓi na abun da ke ciki rabo da kuma shirye-shiryen tsari sigogi, dauri ne tsaka tsaki dakatar watsawa tsarin, wanda ba kawai yana da karfi manne kuma babu lalata zuwa karfe matrix, amma kuma yana da fadi da kewayon aikace-aikace zazzabi na high zafin jiki resistant inorganic ɗaure.

Sodium hexametaphosphateana sanya shi cikin ruwa zuwa sodium dihydrogen phosphate (NaH2PO4) lokacin da aka yi amfani da shi azaman ɗaure a cikin simintin gyare-gyare da feshi. NaH2PO4 da alkaline earth oxides kamar magnesia an shirya su gauraye, za su iya amsawa a dakin da zafin jiki don samar da Mg (H2PO4) 2. Mg (H2PO4) 2 yana bushewa nan da nan don samar da [Mg (PO3) 2] n da [Mg2 (P2O7)] n, wanda ke ƙara ƙarfin hadaddun kuma yana ba da ƙarfi mai ƙarfi akan yanayin zafi mai yawa (har zuwa 800 °).
