1 、 Lub mechanism ntawm kev txhim kho liquidity

Txo tus number case viscosity

SAIB, raws li ib tug polymer plasticizer, tuaj yeem muab tso rau ntawm tus number case molecular chains kom nce qhov sib txawv ntawm cov molecular, txo cov kev sib txhuam tsis sib haum thiab ua kom tus number case yooj yim dua thiab ntws hauv kev luam ntawv siab. Piv txwv li, hauv kev luam ntawv offset, qhov no tuaj yeem txo qhov kev xav tau ntawm kev hloov pauv siab thiab tsis txhob muaj xim xim tsis sib xws los ntawm qhov tsis sib xws.

Optimize leveling yam ntxwv

Cov pawg polar ntawm SAIB daim ntawv cog lus hydrogen nrog tus cwj mem resin, tsim kom muaj kev ruaj ntseg molecular network qauv uas tsis tsuas yog tswj cov ndlwg tus number case, tab sis kuj txhawb kev sib txuas ntxiv ntawm tus number case txheej ntawm lub substrate, txo qhov tsis xws luag xws li txiv kab ntxwv tev qauv ntawm cov ntawv luam tawm.

?

Kho emulsion stability

Cov khoom siv hydrophobic ntawm SAIB tuaj yeem cuam tshuam ntau dhau ntawm emulsification ntawm tus number case nyob rau hauv qhov kev txiav txim ntawm dampening tov, tswj cov theem sab hauv kev ruaj ntseg ntawm tus number case, thiab yog li tswj tau cov fluidity.

2 、 Lub mechanism ntawm kev txhim kho glossiness

Tsim ib zaj duab xis tuab

SAIB txhawb nqa resin cross-linking thaum lub sij hawm number case kom qhuav, tsim ib tug nruam thiab du tus number case zaj duab xis nto, txhim kho daim iav reflection muaj peev xwm ntawm lub teeb. Qhov zoo tshaj plaws glossiness yog tiav thaum tus number case zaj duab xis thickness tswj ntawm 3-5 μ m, raws li ntau thickness yuav ua rau kom muaj zog diffuse reflection.

Synergistic li ntawm resin gloss

Thaum ua ke nrog acrylic resin thiab lwm yam substrates, SAIB txhim kho qhov tsis tu ncua ntawm resin kev npaj los ntawm intermolecular rog, txo qhov roughness (Ra nqi) ntawm tus number case zaj duab xis kom qis dua 0.1 μ m, txhim kho qhov kev xav tau ntawm qhov chaw siab.

?

Regulating pigment dispersion

Cov qauv ester ntawm SAIB tuaj yeem ntim cov xim pigment los tsim steric hindrance, tiv thaiv pigment aggregation thiab sedimentation. Thaum cov pigment particle loj yog tswj nyob rau hauv qhov ntau ntawm 0.2-1 μ m, nws tuaj yeem ua kom cov xim saturation thiab txo cov nplaim tawg tawg.
