DinonylNaphthalenesulfonicAcid(DNNSA) Ndi Cas 25322-17-2
Dinonylnaphthalenesulfonic acid kapena DNNSACAS nambala yake ndi 25322-17-2, ndi mtundu wa mankhwala achilengedwe. Dinonylnaphthalenesulfonic acid solution ndi acidic. Gulu la sulfonic acid (-SO3h) mu molekyulu yake limatha kupereka ma proton, kusonyeza makhalidwe ofanana a ma acid ndipo limatha kuchitapo kanthu ndi ma base, metal oxides, ndi zina zotero.
Dinonylnaphthalenesulfonic acid ndi cationic surfactant, yomwe ingagwiritsidwe ntchito ngati chothandizira pakuphimba komanso ngati zinthu zopangira zoziziritsira (zotsekedwa ndi zosatsekedwa) za utoto wophikira wa amino.
| Maonekedwe | Madzi okhuthala akuda ofiirira |
| Amtengo wa cid(KOH/g) | 60-65 |
| Kuchuluka(g/cm3) | 0.92-0.96 |
| Kukhuthala(Tu - makapu 4 a makapu 20℃) | ≥masekondi 24 |
| Chinyezi | ≤1.0% |
| Zinthu zosasinthasintha | 50-55% |
DNNSA ingagwiritsidwe ntchito ngati chothandizira pakuphimba, ndipo ingagwiritsidwenso ntchito ngati chinthu chachikulu chopangira zinthu zoziziritsira za utoto wophika wa amino. Dinonylnaphthalenesulfonic acid solution ndi yoyenera pamakina opaka utoto wa anodic electrophoretic chifukwa cha hydrophobicity yake. Mumakina opaka utoto wa anodic, dinonylnaphthalenesulfonic acid solution imasamutsa ndikuyika mwachangu, ndipo imalimbikitsa kuchiritsa kwa magulu a hydroxyl, carboxyl ndi amino omwe ali ndi ma amino resins a alkylated. Iyeneranso pamakina opaka utoto wa solvent ndi waterborne kuti iwonjezere kukana dzimbiri. Chifukwa cha mphamvu yake yayikulu yokhazikika Chifukwa chake, DNNSA ndi yoyenera kwambiri kupopera utoto wa electrostatic. Dinonylnaphthalenesulfonic acid DNNSA imagwiritsidwa ntchito pa chitsulo chozungulira, utoto wa can, utoto wamagalimoto, pamwamba pa mafakitale ndi primer. Kuchuluka kowonjezera ndi 0.5--2%, dinonylnaphthalenesulfonic acid imatha kuchepetsa kutentha kwa kuphika ndikufupikitsa nthawi yophika. Nthawi yophika, imawonjezera kuuma ndi kukana kwa mankhwala kwa filimu ya utoto.
Kugwira ntchito bwino kwambiri
Dinonylnaphthalenesulfonic acid ndi yoyenera kugwiritsidwa ntchito pochiza esterification, etherification, condensation reaction (monga kupanga plasticizer, resin covering, njira zina m'malo mwa sulfuric acid catalyst yachikhalidwe zimatha kuchepetsa zotsatirapo zake, kuchepetsa asidi wazinthu); Nthawi yomweyo, imatha kuyambitsa njira yolumikizirana ya zinthu za polima ndikuwonjezera mphamvu zamakanika za zinthuzo.
Kupewa dzimbiri bwino komanso kuletsa dzimbiri
Mu madzi a mafuta odzola, kukonza zitsulo, Dinonylnaphthalenesulfonic acid imakoka filimu yaying'ono ya monomolecular pamwamba pa chitsulo, ndikudula mpweya, madzi ndi zinthu zowononga (monga chifunga cha mchere, ma organic acid). Nthawi yotsutsana ndi dzimbiri ya zitsulo wamba monga chitsulo, mkuwa ndi aluminiyamu imatha kukulitsidwa ndi nthawi ziwiri mpaka zisanu, ndipo sidzakumana ndi zotsatira za mankhwala ndi pamwamba pa chitsulo kuti ipange zinthu zovulaza.
Kusasinthasintha kochepa komanso kukana kutentha kwambiri
Yankho la Dinonylnaphthalenesulfonic acid pansi pa kutentha kwabwinobwino kwa madzi okhuthala, losakhazikika kwambiri lotentha (> 300 ℃), losakhazikika kwambiri (monga mafuta a injini, utoto wotentha kwambiri) lotayika chifukwa cha kusakhazikika, limatha kusunga kukhazikika kwa ntchito kwa nthawi yayitali.
✅Kuchuluka kwa DNNSA kumafika pa 55%, zomwe ndi zokwera kuposa avareji yamsika ya 30% mpaka 50%
✅Mtundu wa Cationic uli ndi ntchito yapamwamba pamwamba
✅Zilipo ndipo nthawi yotumizira ndi yochepa
✅Ubwino wake umayerekezeredwa ndi mtundu waku America wa king1050
Dinonylnaphthalene sulfonic acid yogulitsa kwambiri CAS 25322-17-2.
