Ubuchwepheshe bokukhiqiza kobumba lwe-taphole

Ubuchwepheshe bokukhiqiza bobumba be-taphole:

Ukwakhiwa kobumba lwe-taphole olungenayo i-anhydrous lungahlukaniswa izingxenye ezimbili - i-refractory aggregate kanye ne-binder. I-refractory aggregate ibhekisela ezintweni ezingavuthiwe ezifana ne-corundum, i-mullite, i-coke gem nezinto eziguquliwe njenge-coke ne-mica. I-binder amanzi noma i-tiyela pitch kanye ne-phenolic resin nezinye izinto eziphilayo, kodwa futhi ixutshwe ne-SiC, i-Si3N4, ama-expansion agents kanye ne-admixtures. Hlanganisa ngokuhambisana nobukhulu obuthile nesisindo se-matrix, ekuhlanganisweni kwe-binder ukuze ibe nepulasitiki ethile, ukuze inganono yodaka iqhutshwe emlonyeni wensimbi ukuze ivimbe insimbi eshisayo.
