Ndeupi mutsauko pakati zvidhina zvinokanganisa nechidhinha chakareruka?

Basa guru rezvidhinha zvisinganzwisisiki kuchengetedza kupisa kwekushisa, kuderedza kurasikirwa kwekupisa, nekuvandudza kushanda kwekushisa. Chiyero chesainzi uye chinoshanda chekuchengetedza simba chinogona kudzikisira mwero wekutamisa kupisa.

Pakati pezvinhu zvinoramba, zvidhinha zvisingaremi uye zvidhinha zvinoramba (pasina thermal insulation properties) zvinonyanya kupikisa zvinhu zvinoshandiswa zvakanyanya. Zvisinei, pane musiyano mukuru pakati pezvidhinha zvisingaremi uye zvidhinha zvinoramba.

1, kushanda kwekuchengetedza kupisa

Kupisa kwekupisa kwezvidhinha zvakareruka kunowanzo 0.2～0.4 (avhareji tembiricha 350±25℃) w/mk, uye kupisa kwekushisa kwezvidhinha zvinorambidzika kwakakura kupfuura 1.0 (avhareji tembiricha 350±25℃) w/mk. Nokudaro, kupisa kwekushisa kwezvidhinha zvisinganzwisisiki Performance iri nani pane zvidhinha zvinoramba.

2, kudzivirira moto

Muganho wekudzivirira moto wezvidhinha zvemwenje kazhinji uri pasi pe1400 ℃, uye muganho wekupokana nemoto wezvidhinha zvinoramba uri pamusoro pe1400 ℃.

3, kuwanda

Kuwanda kwezvidhinha zvisingaremi ndeye 0.8-1.0g/cm3, ukuwo kuwanda kwezvidhinha zvinoramba kuri pamusoro pe2.0g/cm3.

Kazhinji kutaura, zvidhinha zvakareruka hazviratidzirwe zvakananga kumoto, tembiricha inonyungudika uye magasi emakemikari. Zvinoenderana neyakasiyana zvinhu uye zvemuviri uye zvemakemikari zvidhinha, refractory zvidhinha zvinogona kushandiswa kukurira kwakasiyana-siyana kunyungudika kwakananga murazvo kubika uye yakakwirira-yekushisa yakanyungudutswa muchoto.

Kubva pakuona kwechiyero chekushandiswa, kushandiswa kwehuwandu hwezvidhinha zvinoramba zvakanyanya kudarika zvidhinha zvisinganzwisisiki. Zvisinei, mumakore achangopfuura, nekuwedzera kwekuziva nezvekuchengetedzwa kwezvakatipoteredza nekuchengetedza simba uye kushandiswa kwepamusoro-kupisa kwekushisa kwekushisa, zvidhinha zvisingaremi zvakashandiswawo zvakanyanya mukutenga kwehuni masonry. Kunyanya, kune marudzi mazhinji matsva ezvidhinha zvisingaremi: zvidhinha zvisingaremi mullite, zvidhinha zvepamusoro-aluminium, uye zvidhinha zvevhu.
