Ceramic ua npuas ncauj tov

Muaj peb qhov teeb meem tseem ceeb uas tuaj yeem cuam tshuam rau npuas hauv kev tsim cov khoom siv ceramics, thiab peb hom npuas sib txawv yog: oxidized npuas, txo npuas thiab glaze npuas.Cia peb ua tib zoo saib cov txheej txheem ntawm kev tsim npuas.

1. Oxidation npuas: Qhov npuas nyiaj txiag no yog tshwm sim los ntawm kev ua tsis tiav oxidation.Muaj cov npuas loj thiab cov npuas me me, vim hais tias ib txheej txheej yog npog nrog ib txheej glaze, yog li peb tsis nquag tawg, thiab feem ntau ntawm cov ntaub ntawv grey cross-sectional yog tsim los ntawm qhov kub thiab txias.

2. Txo ua npuas ncauj: vim tsis txaus reducibility, ua npuas ncauj yog ib tug dawb paug ua npuas ncauj.Nws txoj kab uas hla yog loj dua li ntawm oxidizing ua npuas ncauj, thiab nws hla ntu tig daj.Cov khoom lag luam feem ntau yog tsim los ntawm qhov kub thiab txias ze ntawm qhov hluav taws kub.

3. Glaze npuas: Cov npuas glaze feem ntau me me heev.Lub nruas yog nyob rau saum npoo ntawm txheej glaze, uas yooj yim rau cov tub ntxhais kawm kov nrog lawv txhais tes.Lawv yuav lo rau cov pob dub thaum lawv so.

Rau cov neeg siv uas tsis tau siv ceramic defoamers, nws raug nquahu kom siv cov khoom siv ua tib zoo tsim silicone defoamer, uas tuaj yeem tshem tawm cov teeb meem foaming ntawm ceramics.Tus nqi ntawm defoaming tus neeg saib xyuas yog me me, lub defoaming yog ceev, thiab nws yog resistant rau kub thiab alkali.

Cov haujlwm tshwj xeeb ntawm silicone defoamers yog raws li hauv qab no:

1. Kev kub siab ua haujlwm zoo;

2. Ua rau muaj zog acid thiab alkali (PH tus nqi: 4-14), tshwj xeeb tshaj yog tsim rau defoaming thiab suppressing ua npuas ncauj nyob rau hauv ib puag ncig alkaline;

3. Zoo heev kub thiab shearing tshuab muaj peev xwm;

4. Kev defoaming zoo heev thiab defoaming kev ua tau zoo, uas plays lub luag haujlwm tseem ceeb hauv qhov tsis tshua muaj siab;

5. Kev ua tau zoo ntawm tus kheej emulsifying.
