Ntxiv cov polymers tuaj yeem txhim kho qhov tsis muaj tseeb, kev nruj, tawg tsis kam thiab cuam tshuam ntawm cug thiab qhob. Permeability thiab lwm yam muaj txiaj ntsig zoo. Piv nrog kev txhim kho lub zog thiab txoj kev sib sau ua ke ntawm cug thiab txo nws cov hmoov sib tov ntawm cug thiab txhim kho nws cohesion yog txwv.
Recispersible polymer hmoov feem ntau ua tiav los ntawm cov tshuaj tsuag kom qhuav los ntawm kev siv qee qhov emulsions uas twb muaj lawm. Cov txheej txheem yog ua ntej tau txais polymer emulsion los ntawm emulsion polymerization, thiab tom qab ntawd tau txais nws los ntawm kev tshuaj tsuag qhuav. Txhawm rau tiv thaiv cov agglomeration ntawm looj cov hmoov thiab txhim kho cov khoom ntxiv, tshuaj ntxiv, thiab lwm yam, thaum lub tshuaj tsuag dej kom qhuav, lossis tom qab ziab. Tus neeg sawv cev tso tawm yog ntxiv los tiv thaiv clumping ntawm cov hmoov thaum cia.
Nrog kev nce ntawm cov ntsiab lus ntawm redispersible looj hmoov, tag nrho cov kab ke tsim rau cov yas. Nyob rau hauv cov ntaub ntawv ntawm siab looj cov ntsiab lus, cov roj hmab cov khoom siv tau ntau dua li cov khoom siv hluav taws xob zoo tshaj cov khoom noj muaj txiaj ntsig, thiab cov khoom siv hydring ntawm cov xis mas ua "muab tub lim". Cov. Zaj duab xis tsim los ntawm Redispersible LineX hmoov tau faib rau cov khoom lag luam du thiab tsis muaj cov nplaum uas tsis tshua muaj zog, cov hlau nplaum, vitrified cib thaj, thiab lwm yam) thiab cov organic cov khoom siv nyob hauv cov khoom noj (xws li EPS Cam, Plastics, thiab lwm yam) yog qhov tshwj xeeb tshaj. Vim tias txoj kev sib raug zoo ntawm cov nplaum tsis zoo rau cov ntaub ntawv yog ua tiav los ntawm cov ntsiab lus ntawm lwm yam khoom siv, thiab thaum kawg txuas nrog lub colle rau nws zoo li tus yuam sij hauv lub xauv. Qhov saum npoo ntawm cov khoom, rau qhov kev sib khi saum toj no, tsis tuaj yeem nkag rau hauv cov khoom siv hluav taws xob sab hauv, yog li cov khoom siv sib xyaw ua ke rau nws, thiab cov txheej txheem sib raug zoo ntawm cov polymer sib txawv. , Tus polymer yog sib khi ua ke ntawm lwm cov ntaub ntawv los ntawm kev sib tw ntawm lub ntsej muag (ntawm chav kawm thiab cov npoo av thiab nce kev sib tiv tauj cov adhesion).
