I-DinonylNaphthalenesulfonicAcid (DNNSA) eneCas 25322-17-2
I-Dinonylnaphthalenesulfonic acid okanye inombolo ye-DNNSACAS yi-25322-17-2, luhlobo lweekhompawundi ze-organic. Isisombululo se-Dinonylnaphthalenesulfonic acid si-acidic. Iqela le-sulfonic acid (-SO3h) kwi-molecule yalo linokubonelela ngeeproton, libonise iimpawu eziqhelekileyo ze-acids kwaye linokusabela kwiziseko, ii-metal oxides, njl.njl.
I-Dinonylnaphthalenesulfonic acid yi-cationic surfactant, engasetyenziswa njenge-catalyst yeengubo kunye nezinto eziluhlaza zokuvelisa ii-catalysts zokupholisa (ezivaliweyo nezingavalwanga) zepeyinti yokubhaka ye-amino.

I-DNNSA ingasetyenziswa njenge-catalyst yeengubo, kwaye ingasetyenziswa njengezinto eziphambili zokwenza ii-catalysts zokupholisa iipeyinti zokubhaka ze-amino. Isisombululo se-Dinonylnaphthalenesulfonic acid sifanelekile kwiinkqubo zepeyinti ze-anodic electrophoretic ngenxa yokuba singenamanzi. Kwiinkqubo ze-anodic electrocoat, isisombululo se-dinonylnaphthalenesulfonic acid sidlulisela kwaye sichithe ngokukhawuleza, kwaye sivuselela impendulo yokuphilisa yamaqela asebenzayo e-hydroxyl, carboxyl kunye ne-amino ane-alkylated amino resins. Ikwafanelekile kwiinkqubo zokugquma ezinyibilikayo kunye namanzi ukuphucula ukumelana nokugqwala. Ngenxa yombane wayo ophezulu ongashukumiyo. Ke ngoko, i-DNNSA ifanelekile ngokukodwa ekutshizeni nge-electrostatic. I-Dinonylnaphthalenesulfonic acid I-DNNSA isetyenziselwa intsimbi ye-coil, ipeyinti yekheni, ipeyinti yeemoto, umphezulu wemizi-mveliso ngokubanzi kunye ne-primer. Isixa esongeziweyo yi-0.5--2%, i-dinonylnaphthalenesulfonic acid inokunciphisa ubushushu bokubhaka kwaye inciphise ixesha lokubhaka. Ixesha lokubhaka, ukuphucula ubunzima kunye nokumelana neekhemikhali kwefilimu yepeyinti.
Ukusebenza kakuhle kwe-catalytic
I-Dinonylnaphthalenesulfonic acid ifanelekile kwi-esterification, etherification, condensation reaction (njengokwenziwa kwe-plasticizer, i-resin coating, ezinye iindlela endaweni ye-sulfuric acid catalyst yendabuko zinokunciphisa iziphumo ebezingalindelekanga, zinciphise i-asidi yemveliso); Kwangaxeshanye, inokwenza i-cross-linking reaction yezinto ze-polymer iphucule iipropati zoomatshini zezinto.
Iipropati ezigqwesileyo zokuthintela umhlwa kunye nokuthintela ukugqwala
Kwi-fluid yeoyile yokuthambisa, ukucubungula isinyithi, i-Dinonylnaphthalenesulfonic acid adsorption yenza ifilimu encinci ye-monomolecular kumphezulu wesinyithi, inqumle ioksijini, amanzi kunye nendawo ebolayo (umz., inkungu yetyuwa, ii-asidi ze-organic). Ixesha lokulwa nomhlwa kwiintsimbi eziqhelekileyo ezifana nesinyithi, ubhedu kunye ne-aluminium linokwandiswa amaxesha ama-2 ukuya kuma-5, kwaye aliyi kujongana neekhemikhali kumphezulu wesinyithi ukuvelisa izinto ezinobungozi.
Ukuguquguquka okuphantsi kunye nokumelana nobushushu obuphezulu
Isisombululo se-Dinonylnaphthalenesulfonic acid phantsi kobushushu obuqhelekileyo bolwelo oluqinileyo, oluguquguqukayo kakhulu olubilisa iqondo eliphantsi kakhulu (> 300 ℃), kwimeko yobushushu obuphezulu (njengeoyile yenjini, ipeyinti yobushushu obuphezulu) ekulahlekelweni kokuguquguquka, sinokugcina uzinzo olusebenzayo ixesha elide.
✅Umxholo we-DNNSA ufikelela ngaphezulu kwe-55%, okungaphezulu kunomndilili wemarike we-30% ukuya kwi-50%
Uhlobo lweCationic lunomsebenzi ophezulu womphezulu
✅Ikhona esitokhweni kwaye inexesha elifutshane lokuhambisa
✅Umgangatho ulinganiswa nophawu lwaseMelika iKing1050
I-Dinonylnaphthalene sulfonic acid ethengiswa ngobuninzi i-CAS 25322-17-2.
