Zvidhinha zvealuminium lightweight insulation zvinodzivirira kupisa zvakagadzirwa nebauxite sechinhu chikuru chine Al2O3 isingasviki 48%. Maitiro ayo ekugadzira imhando yefuro, uye inogonawo kushandiswa senzira yekuwedzera kupisa. Zvidhinha zvealuminium lightweight insulation zvinogona kushandiswa semasonry insulation layers uye zvikamu zvisina kukuvadzwa zvakanyanya uye kukuvadzwa kwezvinhu zvakanyungudutswa zvakanyanya. Kana zvakabatana zvakananga nemoto, kazhinji tembiricha yepamusoro yealuminium lightweight insulation haifanirwe kupfuura 1350 °C.
Hunhu hwezvidhinha zvealuminium lightweight insulation
Ine hunhu hwekudzivirira kupisa kwakanyanya, simba rayo guru, huwandu hwayo hwakaderera, porosity yakakwira, thermal conductivity yakaderera, high tembiricha inodzivirira kupisa, uye kushanda zvakanaka kwekudzivirira kupisa. Inogona kuderedza saizi nehuremu hwemidziyo yekupisa, kupfupisa nguva yekupisa, kuve nechokwadi chekuti tembiricha yechoto yakafanana, uye kuderedza kurasikirwa nekupisa. Inogona kuchengetedza simba, kuchengetedza zvinhu zvekuvaka zvechoto uye kuwedzera hupenyu hwebasa rechoto.
Nekuda kwekukwira kwayo kwemvura, huwandu hwayo hushoma uye kushanda kwayo zvakanaka kwekudzivirira kupisa,zvidhinha zvekudzivirira aluminium yakakwira uye yakarerukaAnoshandiswa zvakanyanya sezvinhu zvinodzivirira kupisa munzvimbo iri pakati pezvidhinha zvinodzivirira kupisa uye zvinhu zvechoto mukati memaovheni akasiyana-siyana eindasitiri kuderedza kupisa kwechoto uye kuwana simba rakawanda. Nzvimbo yekunyunguduka yeanorthite i1550°C. Ine hunhu hwe low density, small thermal expansion coefficient, low thermal conductivity, uye kugara kwakasimba mumhepo inoderedza kupisa. Inogona kutsiva ivhu, silicon, uye zvinhu zvinodzivirira kupisa zvine aruminiyamu yakawanda, uye inoita kuti simba richengetwe uye rideredzwe.
