Udaka lwe-Refractory yeXesha Eliphezulu
Ingcaciso yeMveliso
I-refractory mortar luhlobo olutsha lwezinto ezibophelelayo ezingaphiliyo, ezenziwe ngomgubo ezinomgangatho ofanayo nezitena ezifakiweyo, i-inorganic binder kunye ne-admixture.
Ikwahlulahlulwe yaba ziindidi ezimbini, ezizezi, ukusetwa komoya kunye neentlobo zokubeka ubushushu.Iqukethe i-1400, i-1600 kunye ne-1750 iiklasi ezintathu, nganye yazo yahlulwe ngobunzima obulula kunye neentlobo ezinzima.
Udaka lwe-refractory kufuneka lusetyenziswe ngokohlobo lwezitena.
