Thixotropic txuam nrog cov heur

Polyurethane Thickener (Heur)yog dej-soluble ethoxylated polyurethane polymer hloov nrog pawg hydrophobic. Nws yog cov neeg tsis yog-ionic ua rau muaj kev cuam tshuam ua tuab tuab.

Heur muaj ob ntu: Hydrophobic pawg thiab cov amino polyeters. Cov pab pawg hydrophobic yog qee cov tshuaj Macromolecular Alkyl. Hauv cov txheej txheej dej-ua cov txheej txheem, lawv koom nrog cov qauv hydrophobic ntawm lwm cov qauv tshuaj ua haujlwm. Lub Amino Polyet cov saw mus sib txuas tuaj yeem muab tshuaj ruaj khov thiab viscosity stabilability. Polyethylene Glycol yog ib txwm siv los txuas txoj saw los ntawm ownocyanate, thiab tom qab ntawd Alkyl kawg-Capping. Feem ntau, nws muab cov khoom nruab nrab thiab siab shear viscosity. Qhov kev xaiv ntawm cov saw txuas ntxiv tso cai rau cov qauv molecular kom raug xaiv los ntawm linear thiab branched. Tom qab begring, lub rhehol caj pas ntawm polyurethane thickenter kuj hloov pauv (raws li qhia hauv daim duab ntawm polyurethane thickeners uas tsuas tuaj yeem muab cov viscos thiab siab shear viscosity. Nws tseem tuaj yeem muab nruab nrab zoo thiab qis shear viscosity. Cov pab pawg hydrophobic ntawm polyurethane thickener molecules muaj ib qho muaj zog sib xws nrog cov txheej duab txheej, uas tuaj yeem txhim kho cov dej tsis kam ntawm cov yeeb yaj kiab txheej. Vim tias cov lus colloid koom nrog hauv lub koom haum, tsis muaj flocculation yuav tshwm sim, yog li txheej xim zoo nkauj, thiab dej tsis kam ntawm cov txheej muaj tsawg tsawg cuam tshuam. Nws tuaj yeem siv rau hauv dej-raws kos duab kos duab thiab muaj cov txheej txheem txheej txheem.

Qhov nyiaj ntxiv rau hauv cov dej pleev dej yog 0.1-1.0%. Txawm li cas los xij, nyob rau hauv cov dej-follow systems nrog kev haus dej cawv ether cov kev cuam tshuam yuav ploj, thiab cov nyhuv thickening yog tsis muaj.

Lub hydrophobic kawg ntawm cov molecule associates nrog hydrophobic cov qauv xws li cov qauv siv hluav taws xob, thiab cov partichly thiab lwm yam loj ntawm cov emulsion thiab lwm yam sab nraud.
