Umkhono wokuxhuma we-aluminium silicate ngezinye izikhathi ubuye ubizwe ngokuthi ipulaki le-asbestos kanye nekepisi yokuhlukanisa indawo yokuphuma kwesithando somlilo se-aluminium-copper-zinc.Ikakhulukazi yenziwe nge-high-grade aluminium silicate ceramic fibers namanye amafomula ngokwenza i-vacuum.Inokwakheka okuqinile, amandla aphezulu okucindezela, isitoreji sokushisa okuphansi kanye nokulahlekelwa ukushisa okuphansi.Ilungele i-aluminium, ithusi kanye nezinc ezincibilikisa indawo emaphakathi, iziko lokucwenga, izithando zomlilo ezimile, neziko likagesi.I-insulation yokushisa enhle kakhulu kanye nomthelela wokuvala indawo yokuphuma kwamanzi kwenza inqubo yokukhipha i-aluminium-copper-zinc ne-aluminium-copper-zinc alloy ibe lula, iphephe futhi ithembeke kakhudlwana.
