3. Muaj nuj nqi raws li ib tug plating da dej additive rau electroplating ntawm hlau (nickel, tooj liab) los txhim kho txheej uniformity thiab adhesion.
Cia thiab ceev faj
Khaws Methanedisulphonic acid CAS 503-40-2 ntawm 5-25℃hauv PTFE kaw-cov nruas nyob rau hauv qhov txias, qhuav, zoo- qhov cua qhov chaw, deb ntawm noo noo, muaj zog hauv paus, thiab oxidants. Hnav hnab looj tes nitrile, daim npog ntsej muag, thiab cov tshuaj tiv thaiv acid; zam kev tiv thaiv ntawm daim tawv nqaij / qhov muag thiab nqus pa (corrosive). Reseal nruj nreem tom qab siv los tiv thaiv hygroscopic absorption; pov tseg pov tseg ntawm cov ntawv tso cai tshuaj lom neeg.
Dab tsi yog qhov txiaj ntsig ntawm kev noj Methanedisulphonic acid?
✅ Muab Methanedisulphonic acid muaj zog acidity (pKa₁≈-1.2) piv rau sulfuric acid tab sis nrog qis volatility thiab txo kev cuam tshuam ib puag ncig.
✅ Zoo heev Methanedisulphonic acid CAS 503-40-2 solubility nyob rau hauv polar solvents enables homogeneous catalysis yam tsis muaj theem sib cais nyob rau hauv aqueous thiab organic tshuaj tiv thaiv systems.
✅ High thermal stability (decomposes >250 degree) ua kom lub neej ua haujlwm ntev nyob rau hauv siab -cov txheej txheem kev lag luam kub thiab kev siv roj teeb.
