Lub luag haujlwm ntawm RDP hauv pobzeb nplaum yog dab tsi?

Redispersible polymer hmoov (RDP) yog ib hom polymer hmoov uas siv rau hauv pobzeb nplaum los txhim kho cov nplaum nplaum ntawm cov khoom.RDP yog cov hmoov uas yog tsim los ntawm ntau yam polymers, xws li acrylics, vinyl acetate, ethylene, thiab styrene-butadiene copolymer.Nws yog siv los txhim kho qhov adhesion, yooj, thiab dej tsis kam ntawm cov nplais nplaum.

Lub luag haujlwm tseem ceeb ntawm RDP hauv pobzeb nplaum yog txhawm rau txhim kho cov nplaum ntawm cov nplaum rau hauv substrate.Qhov no yog ua tiav los ntawm kev muab kev sib raug zoo ntawm cov nplaum thiab cov substrate.RDP kuj tseem txhim kho qhov yooj yim ntawm cov nplaum, tso cai rau nws txav nrog cov substrate thiab tiv thaiv kev tawg.Tsis tas li ntawd, RDP txhim kho cov dej tsis kam ntawm cov nplaum, tso cai rau nws kom nyob twj ywm txawm tias raug ya raws.

RDP kuj tseem siv los txhim kho kev ua haujlwm ntawm cov nplaum.Qhov no yog ua los ntawm kev txhim kho cov khoom ntws ntawm cov nplaum, ua kom yooj yim rau kev sib kis thiab siv.Tsis tas li ntawd, RDP txhim kho lub sijhawm qhib ntawm cov nplaum, cia nws nyob twj ywm ua haujlwm tau ntev dua.Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum ua haujlwm nrog thaj chaw loj, vim nws tso cai rau tus neeg siv ua tiav txoj haujlwm raws sijhawm.

RDP kuj txhim kho lub zog ntawm cov nplaum.Qhov no yog ua los ntawm kev ua kom lub zog cohesive ntawm cov nplaum, cia nws tsim kom muaj kev sib raug zoo nrog cov substrate.Tsis tas li ntawd, RDP nce lub zog tensile ntawm cov nplaum, cia nws tiv taus ntau zog yam tsis muaj kev tawg.Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum ua haujlwm nrog cov vuas hnyav, vim nws tso cai rau cov nplaum kom nyob twj ywm txawm tias raug hnyav.

Thaum kawg, RDP txhim kho cov khoom zoo nkauj ntawm cov nplaum.Qhov no yog ua los ntawm kev muab ib qho smoother tiav rau cov nplaum, cia nws sib xyaw nrog cov vuas ib puag ncig.Tsis tas li ntawd, RDP txhim kho cov xim ntawm cov nplaum, tso cai rau nws kom phim cov xim ntawm cov vuas.Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum ua hauj lwm nrog cov vuas luaj, vim nws tso cai rau cov nplaum sib xyaw ua ke nrog kev tsim tag nrho.

Hauv kev xaus, RDP yog ib qho tseem ceeb ntawm cov nplais nplaum.Nws txhim kho cov adhesion, yoog raws, dej tsis kam, kev ua haujlwm, lub zog, thiab cov khoom zoo nkauj ntawm cov nplaum.Qhov no tso cai rau cov nplaum tsim kom muaj kev sib raug zoo nrog cov substrate, nyob twj ywm ua haujlwm tau ntev dua, thiab muab kev ua tiav zoo dua.RDP yog ib qho tseem ceeb ntawm cov nplais nplaum, thiab nws siv yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig xav tau.
