DinonylNaphthalenesulfonicAcid (DNNSA) Nrog Cas 25322-17-2
Dinonylnaphthalenesulfonic acid lossis DNNSACAS tus lej yog 25322-17-2, yog ib hom organic compounds. Dinonylnaphthalenesulfonic acid kua yog acidic. Cov sulfonic acid pawg (-SO3h) hauv nws cov molecule tuaj yeem muab protons, qhia txog cov khoom sib xws ntawm cov kua qaub thiab tuaj yeem cuam tshuam nrog cov hauv paus, hlau oxides, thiab lwm yam.
Dinonylnaphthalenesulfonic acid yog ib qho cationic surfactant, uas siv tau ua ib qho catalyst rau cov txheej thiab ua ib qho khoom siv raw rau kev tsim cov catalysts txias (kaw thiab tsis kaw) rau cov xim ci amino.

DNNSA siv tau ua cov tshuaj catalyst rau cov xim pleev xim, thiab kuj siv tau ua cov khoom siv tseem ceeb rau kev tsim cov tshuaj catalysts txias rau cov xim pleev xim amino ci. Dinonylnaphthalenesulfonic acid kua yog qhov tsim nyog rau cov xim pleev xim anodic electrophoretic vim nws cov hydrophobicity. Hauv cov txheej txheem anodic electrocoat, dinonylnaphthalenesulfonic acid kua hloov pauv thiab tso sai sai, thiab catalyzes qhov kev kho mob ntawm hydroxyl, carboxyl thiab amino functional pawg nrog alkylated amino resins. Kuj tsim nyog rau cov kuab tshuaj thiab cov txheej txheem dej los txhim kho kev tiv thaiv corrosion. Vim nws cov hluav taws xob zoo li qub siab Yog li ntawd, DNNSA yog qhov tshwj xeeb tshaj yog rau kev txau electrostatic. Dinonylnaphthalenesulfonic acid DNNSA siv rau cov hlau coil, pleev xim rau hauv lub thawv, pleev xim rau tsheb, nto kev lag luam dav dav thiab primer. Tus nqi ntxiv yog 0.5--2%, dinonylnaphthalenesulfonic acid tuaj yeem txo qhov kub thiab txias ntawm lub sijhawm ci. Lub sijhawm ci, txhim kho qhov tawv thiab tshuaj tiv thaiv ntawm cov xim pleev xim.
Kev ua haujlwm catalytic siab
Dinonylnaphthalenesulfonic acid yog qhov tsim nyog rau esterification, etherification, condensation reaction (xws li kev tsim cov plasticizer, resin coating, lwm txoj hauv kev rau cov tshuaj sulfuric acid catalyst tuaj yeem txo cov kev phiv, txo cov kua qaub ntawm cov khoom); tib lub sijhawm, nws tuaj yeem ua rau muaj kev sib txuas ntawm cov khoom polymer thiab txhim kho cov khoom siv kho tshuab ntawm cov ntaub ntawv.
Kev tiv thaiv xeb zoo heev thiab kev tiv thaiv xeb
Hauv cov kua ntawm cov roj lubricating, cov hlau ua, Dinonylnaphthalenesulfonic acid adsorption tsim cov zaj duab xis compact monomolecular ntawm qhov chaw hlau, txiav tawm cov pa oxygen, dej thiab cov khoom siv corrosive (piv txwv li, ntsev pos huab, cov organic acids). Lub sijhawm tiv thaiv xeb rau cov hlau feem ntau xws li hlau, tooj liab thiab txhuas tuaj yeem ntev dua 2 txog 5 zaug, thiab nws yuav tsis dhau cov tshuaj lom neeg nrog cov hlau nto los tsim cov tshuaj lom neeg.
Kev hloov pauv tsawg thiab kev tiv taus cua sov siab
Cov kua dinonylnaphthalenesulfonic acid nyob rau hauv qhov kub ib txwm rau cov kua viscous, volatile boiling point qis heev (> 300 ℃), nyob rau hauv qhov kub siab (xws li roj cav, xim kub siab) hauv qhov poob ntawm volatile, tuaj yeem tswj kev ruaj khov ua haujlwm ntev.
✅Cov ntsiab lus DNNSA ncav cuag ntau dua 55%, uas yog siab dua li qhov nruab nrab ntawm kev ua lag luam ntawm 30% txog 50%
✅Hom cationic muaj kev ua haujlwm ntawm qhov chaw siab dua
✅Muaj nyob hauv Tshuag thiab nrog lub sijhawm xa khoom luv luv
✅Qhov zoo tau raug ntsuas piv rau lub npe nrov Asmeskas king1050
