MES 4-Morpholinoethanesulfonic acid 99% purity CAS 4432-31-9
4-Morpholineethanesulfonic acid yog ib qho amphoteric tsis, uas muaj txiaj ntsig zoo nyob rau hauv pH ntau ntawm 5.5-7.7. Raws li qhov tsis zoo, MES tau siv dav hauv cov nroj tsuag kab lis kev cai nruab nrab, reagent tov thiab physiological xyaum ua kom kho tus nqi pH. Nws muaj cov tshuaj detergency siab, zoo heev calcium xab npum dispersion thiab tawv dej tsis kam.

1. Siv los ua calcium xab npum dispersant hauv xab npum thiab xab npum. Nws tuaj yeem hloov tau sodium tripolyphosphate ua cov tshuaj tsis muaj phosphorus lossis phosphorus dawb. Nws kuj tseem siv tau los ua cov khoom siv hauv cov kua ntxhua.
2. Siv los ua cov npuas nruab nrab ntxhia flotation tus neeg sawv cev hauv kev lag luam.
3. Nyob rau hauv tawv degreasing, dyes, pigments, tshuaj tua kab raws li dispersant, wetting agent.
4. Siv los ua tus neeg sawv cev deinking hauv kev lag luam luam ntawv.
Ntim rau hauv 25kgs nruas thiab khaws cia kom deb ntawm lub teeb ntawm qhov kub ntawm 25 ℃.
