Product Overview
Raws li Tuam Tshoj -raws li cov chaw tsim khoom, Alfa Chemical khoom sivNafion® perfluorinated resin tov (CAS 31175-20-9)los ntawm Zhengzhou. Nws yog ibPFSA dispersionntawm 20 wt.% hauv qis aliphatic cawv thiab dej. Cov pob txha polymer yog fluorinated tag nrho; cov pab pawg sulfonic acid muab nws ib qho ion- pauv peev xwm ntawm 1.03–1.12 meq/g.
Cov neeg yuav khoom siv qhov kev faib tawm no rau ob yam. Ua ntej,membrane casting rau PEM roj hlwb: cov tshuaj yog coated, cov kuab tshuaj evaporates, thiab qhov seem yog proton- ua zaj duab xis. Thib ob,khoom superacid catalysis: nyob rau hauv nws cov kua qaub daim ntawv, cov qhuav resin ua hauj lwm raws li ib tug heterogeneous catalyst rau esterification, alkylation, thiab isomerization - thiab tsis zoo li sulfuric acid, nws yuav lim tawm thiab rov qab siv dua.
Ib pab pawg me siv nws los hloov cov electrode nto hauvelectrochemical sensors. Yog tias koj tab tom ua haujlwm ntawm cov roj hlwb, electrolyzers, lossis cov khoom siv -acid catalysis, qhov no yog qib pib nrog. Hais txoglife science thiab biochemical khoomkuj muaj.
