Ndeipi nzira yekurapa anti-alkali chaiyo zvidhinha zvinopesana?

1. Direct kuonana kunyungudutsa kukurwa nzira. Pasi pepamusoro-tembiricha yekuisa chisimbiso, iyo simbi yakanyungudutswa inosangana yakanangana neiyo test block for corrosion reaction kuyera shanduko yezvinhu zvakasiyana-siyana isati yaitwa uye mushure mekunge sampu yaora. Nzira mbiri idzi dzinoshandisa diki shanduko kuratidza alkali kuramba kwepamusoro alumina refractory zvidhinha. Zviri nani.

2. Mixed erosion method. Iyo coke particles inosanganiswa neanhydrous K2CO3, test block inovigwa mairi, uye test block inoputirwa pasi pepamusoro-tembiricha yekuisa chisimbiso kuti ione shanduko yehukuru kana chiyero chekudzikisa simba reye test block isati yanyungudika uye mushure mekunge yakukurwa.

3. Iko kupikisa kwealkali kwezvidhinha zvinoramba ndiko kukwanisa kwepamusoro alumina refractory zvidhinha kupikisa alkali corrosion pakupisa kwakanyanya. Mukuputika kwechoto chekunyungudutsa, zvidhinha zvinoramba zvichange zvakasvibiswa nealkali. Semuyenzaniso, kana mbishi yakawedzerwa kune alkali-ine zvicherwa, kukukurwa kweaya maminera ane alkali parukungiso rwealuminium-silicon uye kabhoni refractory zvidhinha kunokanganiswa nealkali concentration, tembiricha uye mhute yemvura, ine chekuita nebasa. hupenyu hwekuputika kwevira remoto uye inovandudza kushorwa kwezvidhinha zvinoramba. Kuita kwealkali kunowedzera hupenyu hwesevhisi yekuputika kwevira.
