ʻO DinonylNaphthalenesulfonicAcid (DNNSA) Me Cas 25322-17-2
ʻO ka Dinonylnaphthalenesulfonic acid a i ʻole ka helu DNNSACAS ʻo 25322-17-2, he ʻano hui organik. He waikawa ka hopena o ka waikawa Dinonylnaphthalenesulfonic. Hiki i ka hui waikawa sulfonic (-SO3h) i loko o kāna molekala ke hāʻawi i nā protons, e hōʻike ana i nā waiwai maʻamau o nā waikawa a hiki ke hana me nā kumu, nā oxides metala, a pēlā aku.
He surfactant cationic ka Dinonylnaphthalenesulfonic acid, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoulu no nā uhi a ma ke ʻano he mea maka no ka hana ʻana i nā mea hoʻoulu hoʻoluʻu (pani ʻia a pani ʻole ʻia) no ka pena hoʻomoʻa amino.

Hiki ke hoʻohana ʻia ʻo DNNSA ma ke ʻano he mea hoʻoulu no nā uhi ʻana, a hiki ke hoʻohana ʻia hoʻi ma ke ʻano he mea maka nui no ka hana ʻana i nā mea hoʻoulu hoʻoluʻu no nā pena bakena amino. He kūpono ka hopena waikawa Dinonylnaphthalenesulfonic no nā ʻōnaehana pena electrophoretic anodic ma muli o kona hydrophobicity. I loko o nā ʻōnaehana electrocoat anodic, hoʻoili a waiho koke ka hopena waikawa dinonylnaphthalenesulfonic, a hoʻoulu i ka hopena hoʻōla o nā hui hana hydroxyl, carboxyl a me nā amino me nā resins amino alkylated. He kūpono hoʻi no nā ʻōnaehana uhi solvent a me ka wai e hoʻomaikaʻi i ke kūpaʻa ʻana i ka corrosion. Ma muli o kona uila static kiʻekiʻe No laila, kūpono loa ʻo DNNSA no ka pīpī electrostatic. Hoʻohana ʻia ka waikawa Dinonylnaphthalenesulfonic DNNSA no ke kila coil, ka pena hiki, ka pena kaʻa, ka ʻili ʻoihana maʻamau a me ka primer. ʻO ka nui o ka hoʻohui he 0.5--2%, hiki i ka waikawa dinonylnaphthalenesulfonic ke hōʻemi i ka mahana bakena a hoʻopōkole i ka manawa bakena. Hoʻomaikaʻi ka manawa bakena i ka paʻakikī a me ke kūpaʻa kemika o ka ʻili pena.
Ka pono catalytic kiʻekiʻe
He kūpono ka Dinonylnaphthalenesulfonic acid no ka esterification, etherification, a me ka condensation reaction (e like me ka synthesis o ka plasticizer, ka uhi ʻana o ka resin, a me nā mea ʻē aʻe i ka mea hoʻouluulu sulfuric acid kuʻuna e hōʻemi i nā hopena ʻaoʻao, a hoʻemi i ka waikawa huahana); I ka manawa like, hiki iā ia ke hoʻoulu i ka hopena cross-linking o nā mea polymer a hoʻonui i nā waiwai mechanical o nā mea.
Nā waiwai pale maikaʻi loa i ka popo a me ka pale ʻana i ka corrosion
I loko o ke kahe o ka ʻaila lubricating, ka hana ʻana i ka metala, hoʻokumu ka adsorption acid Dinonylnaphthalenesulfonic i kahi kiʻiʻoniʻoni monomolecular compact ma luna o ka ʻili metala, e ʻoki ana i ka oxygen, ka wai a me ka mea corrosive (e laʻa, ka noe paʻakai, nā waikawa organik). Hiki ke hoʻolōʻihi ʻia ka manawa anti-rust no nā metala maʻamau e like me ke kila, ke keleawe a me ka alumini i 2 a 5 mau manawa, a ʻaʻole ia e hana i nā hopena kemika me ka ʻili metala e hana i nā mea ʻino.
Haʻahaʻa haʻalulu a me ke kūpaʻa wela kiʻekiʻe
ʻO ka hopena waikawa Dinonylnaphthalenesulfonic no ka wai viscous ma lalo o ka mahana maʻamau, haʻahaʻa loa ka paila ʻana o ka pahū (> 300 ℃), i ke kūlana wela kiʻekiʻe (e like me ka ʻaila mīkini, pena wela kiʻekiʻe) i ka nalowale o ka pahū, hiki ke mālama i ka paʻa hana no ka manawa lōʻihi.
✅Ua piʻi aku ka ʻike o ka DNNSA ma mua o 55%, ʻoi aku ke kiʻekiʻe ma mua o ka awelika o ka mākeke o 30% a 50%
✅ʻOi aku ka hana o ka ʻili o ke ʻano cationic
✅ Loaʻa i ka waihona a me kahi pōʻaiapuni hoʻouna pōkole
✅Ua hoʻohālikelike ʻia ke ʻano me ka hōʻailona ʻAmelika king1050
