Ma’anar raunin da bai daidaita ba

Unshaped refractory abu: Abubuwan da ba a daidaita su ba sun kasance cakuda abubuwan tarawa, foda, binder ko wasu ƙari a cikin wani rabo, kuma ana iya amfani da su kai tsaye ko gauraye da ruwa mai dacewa. A takaice dai, matsewar wani sabon salo ne mai ratsa jiki ba tare da calcination ba, kuma raguwar sa ba kasa da 1580 ° C ba.

Foda: wanda kuma aka sani da foda mai kyau, yana nufin ɗaya daga cikin abubuwan da ke cikin tsarin kayan ƙyalli na amorphous tare da girman barbashi ƙasa da 0.088mm, wanda ke aiki azaman haɗi zuwa tarawa a yanayin zafi don samun kaddarorin jiki da na injiniya da aiki. Farin foda zai iya cika pores na jimlar, bayarwa ko inganta aikin sarrafawa da taɓarɓarewar abubuwan ƙin amorphous.

Ƙididdiga: yana nufin kayan ƙira tare da girman barbashi fiye da 0.088mm. Yana da babban abu a cikin tsarin amorphous refractories kuma yana taka rawar kwarangwal. Yana ƙayyade kaddarorin jiki da na injiniya da kaddarorin zazzabi mai yawa na kayan ƙin amorphous, kuma shine mahimmin tushe don tantance kaddarorin kayan aiki da iyakokin aikace-aikacen.

Binder: yana nufin kayan da ke haɗa madaidaiciyar madaidaiciya da foda tare kuma yana nuna wani ƙarfi. Binder wani muhimmin sashi ne na kayan jujjuyawar amorphous kuma ana iya amfani dashi don kayan inorganic, Organic da kayan haɗin gwiwa. Manyan nau’ikan sune siminti, gilashin ruwa, acid phosphoric, sol, resin, yumbu mai laushi da wasu ƙaƙƙarfan ƙaho.

Ƙari: Abu ne wanda zai iya haɓaka aikin haɗin gwiwa da haɓaka aikin matrix lokaci. Yana da wani irin refractory tara, ainihin abu hada da refractory foda da m, shi kuma ake kira ƙari. Irin su robobi, masu hanzari, masu ba da gudummawa, kayan ƙonawa, wakilan faɗaɗa, da sauransu.

Bugu da ƙari, don ƙyalli mai ƙoshin foda, an ƙayyade cewa girman barbashi ƙasa da 5μm don foda mai kyau, kuma ƙasa da 1μm don foda mai ƙyalli.
