Dinonyl NaphthalenesulfonicAcid (DNNSA) Nrog Cas 25322-17-2
Dinonylnaphthalenesulfonic acid yog cationic surfactant, uas tuaj yeem siv los ua cov khoom siv rau txheej txheej thiab ua cov khoom siv raw rau kev tsim cov cua txias catalysts (kaw thiab tsis-kaw) rau cov amino ci xim.

DNNSA tuaj yeem siv los ua cov txheej txheem rau txheej txheej, thiab tseem tuaj yeem siv los ua cov khoom siv tseem ceeb rau kev tsim cov cua txias catalysts rau cov xim ci amino. Dinonylnaphthalenesulfonic acid tov yog haum rau anodic electrophoretic xim tshuab vim nws hydrophobicity. Hauv anodic electrocoat systems, dinonylnaphthalenesulfonic acid tov hloov pauv thiab tso nyiaj sai, thiab catalyzes kho cov tshuaj tiv thaiv ntawm hydroxyl, carboxyl thiab amino functional pawg nrog alkylated amino resins. Kuj tseem haum rau cov kuab tshuaj thiab cov txheej txheem dej los txhim kho corrosion. Vim nws cov hluav taws xob zoo li qub yog li ntawd, DNNSA yog tshwj xeeb tshaj yog haum rau electrostatic txau. DNNSA yog siv rau coil steel, tuaj yeem pleev xim, xim tsheb, kev lag luam dav dav thiab primer. Cov nyiaj ntxiv yog 0.5--2%, uas tuaj yeem txo qhov kub thiab txias lub sijhawm ci. Lub sij hawm ci, txhim kho hardness thiab tshuaj tiv thaiv ntawm cov xim zaj duab xis.
