MES 4-Morpholinoethanesulfonic acid 99% purity nrog CAS 4432-31-9
4-Morpholineethanesulfonic acid yog ib qho amphoteric buffer, uas ua haujlwm tau zoo hauv pH ntawm 5.5-7.7. Ua ib qho khoom zoo buffer, MES yog siv dav hauv cov nroj tsuag cog qoob loo, cov tshuaj reagent thiab kev sim physiological los kho tus nqi pH. Nws muaj kev ntxuav siab, kev sib kis zoo ntawm xab npum calcium thiab kev tiv thaiv dej tawv.

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