I-DinonylNaphthalenesulfonic Acid (DNNSA) ene-Cas 25322-17-2
I-Dinonylnaphthalenesulfonic acid noma inombolo ye-DNNSACAS ingu-25322-17-2, uhlobo lwamakhemikhali e-organic. Isixazululo se-Dinonylnaphthalenesulfonic acid sinobuthi. Iqembu le-sulfonic acid (-SO3h) ku-molecule yalo linganikeza ama-proton, libonise izakhiwo ezivamile zama-acid futhi lingasabela nezisekelo, ama-metal oxides, njll.
I-Dinonylnaphthalenesulfonic acid iyi-cationic surfactant, engasetshenziswa njengesikhuthazi sezingubo kanye nezinto zokusetshenziswa ekukhiqizeni ama-catalyst okupholisa (avaliwe nangakavalwa) opende wokubhaka we-amino.

I-DNNSA ingasetshenziswa njengesikhuthazi sezingubo zokumboza, futhi ingasetshenziswa njengento eluhlaza eyinhloko yokukhiqiza ama-catalyst okupholisa amapende okubhaka ama-amino. Isixazululo se-Dinonylnaphthalenesulfonic acid sifanele izinhlelo zokupenda ze-anodic electrophoretic ngenxa yokungangeni kwamanzi. Ezinhlelweni ze-anodic electrocoat, isixazululo se-dinonylnaphthalenesulfonic acid sidlulisa futhi sichithe ngokushesha, futhi sivuselela ukusabela kokwelapha kwamaqembu asebenzayo e-hydroxyl, carboxyl kanye nama-amino ane-alkylated amino resins. Sifanele futhi izinhlelo zokugqoka ezi-solvent kanye nezamanzi ukuze kuthuthukiswe ukumelana nokugqwala. Ngenxa kagesi wayo ophezulu ongaguquki Ngakho-ke, i-DNNSA ifaneleka kakhulu ekufuthweni kwe-electrostatic. I-Dinonylnaphthalenesulfonic acid I-DNNSA isetshenziselwa insimbi ye-coil, upende we-can, upende wezimoto, ubuso bezimboni obujwayelekile kanye ne-primer. Inani lokwengeza lingu-0.5--2%, i-dinonylnaphthalenesulfonic acid inganciphisa izinga lokushisa lokubhaka futhi ifinyeze isikhathi sokubhaka. Isikhathi sokubhaka, sithuthukise ubulukhuni kanye nokumelana kwamakhemikhali kwefilimu yopende.
Ukusebenza kahle okuphezulu kwe-catalytic
I-Dinonylnaphthalenesulfonic acid ifaneleka esterification, etherification, condensation reaction (njengokwenziwa kwe-plasticizer, resin coating, ezinye izindlela esikhundleni se-sulfuric acid catalyst yendabuko kunganciphisa imiphumela emibi, kunciphise i-acid yomkhiqizo); Ngesikhathi esifanayo, ingavuselela ukusabela kokuxhumanisa kwezinto ze-polymer futhi ithuthukise izakhiwo zemishini zezinto.
Izakhiwo ezinhle kakhulu zokuvimbela ukugqwala kanye nokuvimbela ukugqwala
Kuketshezi lwamafutha okugcoba, ukucubungula insimbi, i-Dinonylnaphthalenesulfonic acid adsorption yakha ifilimu encane ye-monomolecular ebusweni bensimbi, inqume umoya-mpilo, amanzi kanye nendawo ebolile (isb., inkungu kasawoti, ama-organic acid). Isikhathi sokulwa nokugqwala kwezinsimbi ezivamile njengensimbi, ithusi kanye ne-aluminium singandiswa izikhathi ezi-2 kuya kwezi-5, futhi ngeke sibhekane nokusabela kwamakhemikhali ebusweni bensimbi ukuze kukhiqizwe izinto eziyingozi.
Ukuguquguquka okuphansi kanye nokumelana nokushisa okuphezulu
Isixazululo se-Dinonylnaphthalenesulfonic acid ngaphansi kokushisa okujwayelekile koketshezi oluqinile, iphuzu lokubilisa eliguquguqukayo eliphansi kakhulu (> 300 ℃), esimweni sokushisa okuphezulu (njengowoyela wenjini, upende wokushisa okuphezulu) ekulahlekelweni kokuguquguqukayo, singagcina ukuzinza kokusebenza isikhathi eside.
✅Okuqukethwe kwe-DNNSA kufinyelela ngaphezu kuka-55%, okuphakeme kunesilinganiso semakethe esingu-30% kuya ku-50%
✅Uhlobo lwe-Cationic lunomsebenzi ophezulu wobuso
✅Ikhona esitokweni futhi inomjikelezo omfushane wokulethwa
✅Ikhwalithi ilinganiswa nomkhiqizo waseMelika i-king1050
I-Dinonylnaphthalene sulfonic acid ethengiswa ngobuningi i-CAS 25322-17-2.
