Aluminium silicate plugging sleeve dzimwe nguva inonziwo asbestos plug uye insulation cap yekubuda kwearuminiyamu-mhangura-zinc yekunyungudutsa choto.Iyo inonyanya kugadzirwa neyepamusoro-giredhi aluminium silicate ceramic fibers uye mamwe mafomula nevacuum kugadzira.Iine maitiro akaoma, simba rakakwirira rekumanikidzika, kuchengetedzwa kwekushisa kwakadzika uye kurasikirwa kwekupisa.Inokodzera aluminium, mhangura uye zinc centralized kunyunguduka mavira, kunatsa mavira, static furnaces, uye magetsi emagetsi.Iyo yakanakisa kupisa kupisa uye kuvhara mhedzisiro yekubuda kwemvura kunoita kuti maitiro ekukanda ealuminium-mhangura-zinc uye aluminium-mhangura-zinc alloy zviri nyore, zvakachengeteka uye zvakavimbika.
