1. Waa maxay waxyaabaha dib-u-dejinta? Waa maxay noocyada ugu waaweyn ee qalabka dib-u-noqoshada?
Refractory materials refer to inorganic non-metallic materials that can maintain stable physical and chemical properties in high temperature environments. They are mainly used for linings of high-temperature equipment such as furnaces, boilers, furnaces and reactors. According to composition and use, refractories can be divided into the following categories: clay refractories, high-alumina refractories, siliceous refractories, Diyaarinta magnesonia iyo dib-u-habeynta kaarboon {{5 {5 {5 {5 {5 {5 {5 {5} inta badan waxay ka kooban yihiin aluminium silical waxaana badanaa lagu isticmaalaa warshadaha metallag iyo dhalada; Dib-u-habeynta alumina sare waxaa ku jira alumina sare oo ku habboon warshadaha birta; Helsices siliceus waxaa ku jira silicon sare waxayna leeyihiin iska caabin aashito xoog leh; Feejignaanta magnesia inta badan waxaa ka kooban magnesium oxide waxayna leeyihiin iska caabin alkali ah oo xoog leh; Dib-u-habeyn kaarboon ah ayaa inta badan ka kooban jaantus iyo silicon carbide waxayna ku habboon yihiin heerkulka sare iyo jawiga isku-dhafka ah ee .
2. waa maxay arrimaha saameeya nolosha adeegga ee qalabka dib-u-noqoshada?
Nolosha adeegga ee qalabka dib-u-noolaynta waxaa saameeya arrimo badan, oo ay ku jiraan heerkulka, walaaca kiimikada, oo ay ku dhacdo gaas-heerkulka, sida aashitada ama gaaska aashitada iyo dareeraha ah ee foornada, ayaa sababi doonta Qabowyada iyo ka sii darida agabyada dib-u-noqoshada {{3} marka lagu daro walwalka farsamada, sida saamaynta muuqaalka, taasi waa awooda in heerkulka uu isbadalo, sidoo kale waa cunsur aad u muhiim ah oo saameyn ku leh nolosheeda ..
3. sida loo doorto sheyga saxda ah?
Waxaa jira qodobo badan oo la tixgeliyo marka aad dooraneyso waxyaabaha saxda ah ee heerkulka ah, oo ah walxaha kiimikaad ee jawiga ugu sarreeya, sida ay tahay in sifooyinku ay tahay in la tixgeliyo, sida doorashada silica silic ah Qalabka jawiga aashitada iyo qalabka caarada magnesium ee deegaanka alkaline {{2} marka lagu daro walwalka farsamada iyo adkaanta ee loo baahan yahay in lagu xusho si joogto ah, oo ah in lagu xusho si looga hortago in si looga hortago dildilaaca iyo is-dhexgalka {{4}
