Looj yog ib tug ruaj khov emulsion (ncua kev kawm ntawv, slurry), qhov twg linking puag thiab pigments yog tshem tawm (dispersed) nyob rau hauv ib tug aqueous nruab nrab. Nws hloov tawm hais tias dilutes cov dej thiab tsis yaj zoo hais ntawm polymers uas yog nyob rau hauv ib tug tshem tawm xeev. Tom qab uas tseg tau, cov dej suab thiab lub polymer yog tsim ntawm ib tug khoom zaj duab xis. Tom qab tias lub saum npoo yog tsis ntshai ntawm dej.

Nyob rau hauv tas li ntawd, lub latex muaj ib tug xov tooj ntawm zoo. Nws tsis muaj ib tug muaj zog tsw, tsis emit noxious pa taws, lub pleev xim rau saum npoo yuav muab tau yooj yim ntxuav.

Muaj acrylic, silicone thiab silicate vodoemulsionku. Cov yooj yim acrylic cob puag neeg tshwj xeeb haum. Tej ntaub ntawv muaj siab zog thiab elasticity, tab sis lawv cov nqi yog heev siab heev.

Acrylic latex yog tib yam li cov hnab looj xim, lawv tsuas ntxiv mus rau lub latex, uas tso cai rau koj mus cuag ib tug tseem ceeb dej-repellent nyhuv. Ib qho tseem ceeb khoom teejtug uas yog latex xim tsev yog lawv vapor permeability, uas tsis cuam tshuam nrog cov dej-repellent zog. Cov uas ua txheej xim polymer zaj duab xis yog muaj peev xwm sawv ntawm tiv ntau tshaj tsib txhiab mus nrog ib tug txhuam. Nyob rau hauv lwm yam lus, tus nto yuav raug tshem tawm mus ntxuav zoo unlimited tooj ntawm lub sij hawm.

Base silicone latex xim yog ib tug aqueous dispersion ntawm ib tug silicone cob. Cov inks yog cov feem ntau niaj hnub thiab combines qhov zoo tshaj plaws zoo. Coated rau lawv nto siv tshuam tsis wetted, lawv ib txhij tso roj thiab chav. Cov zog tso cai rau cov kev siv ntawm silicone xim nyob rau hauv tshiab plastered chaw, lawv yuav tsis tiv thaiv kom txhob hardening plaster. Cov tau ntawm dej-xim thaum ua ntawv thov mus rau qhov chaw no mas tsis tshua.

Roj hmab cov xim tsev yog tsis txhoj puab heev thiab muaj lub siab ductility. Lawv cia daim npog qhov ncauj kab nrib pleb li ob millimeters, thiab cov kho nto yuav tsis muaj me tub kab.

Lub silicone latex yog siv nyob rau hauv yuav luag tag nrho cov hom ntawm cov mineral chaw. Nws yog sib xws nrog ob latex thiab acrylic xim tsev los yog mineral. Lawv yog cov yooj yim mus siv nyob rau hauv tag nrho cov hom ntawm kev ua hauj lwm. Ua, piv txwv li, cov dej tsis zoo ntawm lwm tus lub tsev nrog lawv tus kheej txhais tes, tag nrho cov yam ntxwv hais yuav coated nrog cov xim tsev.
