Deskripsyon pwodwi
Konpozan prensipal yo nan brik dife difisil yo se ajil ak kaolin, epi anjeneral yon sèten pwopòsyon nan sab kwatz, boksit, gang chabon ak lòt matyè premyè oksilyè yo ajoute. Kontni ajil la anjeneral ant 50% ak 70%, ak kontni an nan kaolin se ant 10% ak 30%.
Avantaj nan brik dife difisil
Brik dife difisil gen bon rezistans dife: brik dife ajil gen bon rezistans tanperati ki wo, anjeneral ka kenbe tèt ak tanperati ki wo pi wo a 1000 degre, ak kèk ka menm rive nan tanperati ki wo pi wo a 1500 degre.
Brik dife difisil gen gwo rezistans korozyon: ajil ak kaolin nan materyèl brik refractory ajil gen gwo silikat ak aluminate, ki ka reziste asid divès kalite, alkali, sèl ak lòt korozyon chimik, kidonk li se lajman ki itilize nan endistri chimik, metaliji, pouvwa elektrik ak lòt jaden.
