Corundum mullite chidhinha

Zvigadzirwa zvechigadzirwa: yakanyanya kupisa tembiricha, ngura kuramba, oxidation kuramba, yakanaka yekupisa kugadzikana, uye yakaderera mitsara shanduko chiyero.

Chigadzirwa chishandiso: Inonyanya kushandiswa mu petrochemical indasitiri, hombe uye yepakati-saizi synthetic ammonia gasi uye magineti zvinhu gasi chira zvinhu, yakanyanya-tembiricha maindasitiri hira inotsigira zvivakwa zvinhu, nezvimwe.

chigadzirwa tsanangudzo

Corundum uye mullite zvidhinha zvakagadzirwa neiyo yakachena-kuchena corundum uye mullite kunge mbishi zvigadzirwa, zvakaumbwa neakanyanya kumanikidza uye nekupisa pakakwirira tembiricha. Chigadzirwa chine hunhu hwekupisa kwakanyanya kupisa, kurwisa ngura, kusagadzikana kweiyo oxidation, kudzikama kwakanaka kwemafuta, uye yakaderera mitsara yekuchinja chiyero.

Tsananguro yekorundum mullite zvidhinha:

1. Zvinhu zvinorema zvine compactness yakanaka, yakasimba compressive simba, kuramba kune akasiyana gasi anoparadza, yakanaka yekupisa yekuvhundutsa kugadzikana, kwakanyanya kupisa kwekushisa, uye kupfeka kuramba.

2. Zvinhu zvisina kuremerwa zvine yunifomu yemukati dhizaini, yakasimba yekumanikidza simba, kurwisa ngura, kupisa kupisa kupisa, oxidation kuramba, yakanyanya sevhisi tembiricha uye yakaderera thermal conductivity.
