Dyeing yog txoj kev nrov tshaj plaws ntawm kev kho kom zoo nkauj. Hom kev ua tiav no yog ib qho yooj yim tshaj plaws, tab sis nws muaj peev xwm tsis muaj kev txwv rau tus kheej style thiab creativity.
Cov xim pleev xim dej yog qhov zoo tshaj plaws rau kev pleev xim, uas tuaj yeem siv rau sab hauv thiab sab nrauv lub tsev. Cov khoom no yog ib qho yooj yim mus use, tsis txhoj puab heev, nrog kev pab los ntawm ib tug pigment koj yuav tau yooj yim hloov nws cov xim, tau txais ntau yam ntxoov ntxoo.
Cov xim pleev xim rau dej yog qhov ruaj khov emulsion (sab laug, slurry), qhov twg cov binder puag thiab pigments raug tshem tawm (dispersed) hauv nruab nrab aqueous. Nws hloov tawm hais tias dej dilutes es dissolves me me ntawm polymers uas nyob rau hauv ncua kev kawm ntawv. Tom qab dyeing, dej evaporates, thiab cov khoom siv zaj duab xis yog tsim nrog kev pab los ntawm polymers. Tom qab ntawd, saum npoo tsis ntshai lawmnoo noo.
Tsis tas li ntawd, cov xim pleev xim dej muaj ntau yam zoo. Nws tsis muaj ntxhiab tsw ntxhiab, tsis tawm cov pa phem, thiab cov xim pleev xim tuaj yeem ntxuav tau yooj yim.
Muaj acrylic, silicone thiab silicate dej emulsions. Hauv acrylic, tshwj xeeb resins yog lub hauv paus ntsiab lus. Cov ntaub ntawv zoo li no muaj zog thiab elasticity, tab sis lawv cov nqi yog siab heev.
Acrylic latex paints yog tib yam dej-dispersion xim, tsuas yog latex ntxiv rau lawv, uas ua rau nws muaj peev xwm ua tau kom muaj txiaj ntsig zoo ntawm cov dej-tiv taus. Cov cuab yeej tseem ceeb ntawm cov xim latex yog lawv cov vapor permeability, uas tsis cuam tshuam nrog cov dej-repellent zog. Cov yeeb yaj kiab polymer tau txais los ntawm kev siv cov xim muaj peev xwm tiv taus ntau tshaj tsib txhiab txhuam hniav. Hauv lwm lo lus, qhov chaw tuaj yeem raug ntxuav, ntxuav yuav luag tsis pub dhau lub sijhawm.
Lub hauv paus ntawm silicone dej-raws li xim yog ib qho aqueous dispersion ntawm silicone resin. Cov xim no yog cov niaj hnub tshaj plaws thiab sib xyaw ua ke txhua qhov zoo tshaj plaws. Qhov saum npoo npog nrog lawv yog xyaum tsis wetted, tib lub sij hawm lawv kis tau roj thiab chav. Cov khoom no ua rau nws tuaj yeem siv cov xim silicone rau ntawm qhov chaw tshiab plastered, lawv yuav tsis cuam tshuam nrog lub hardening ntawm plaster. Nyob rau tib lub sijhawm, kev siv cov xim pleev xim dej thaum siv rau saum npoo yog txausqis.
Cov xim silicone tsis yog txhoj puab heev thiab muaj cov yas siab. Lawv tso cai rau koj los npog cov kab nrib pleb txog li ob millimeters dav, thiab kab tsis tuaj yeem yug los ntawm qhov chaw kho.
Silicone dej-raws li xim yog siv rau yuav luag txhua hom pob zeb hauv av. Nws yog sib xws nrog ob qho tib si latex thiab acrylic lossis ntxhia xim. Lawv yooj yim siv rau txhua yam haujlwm. Tau ua, piv txwv li, kev siv dej ntawm lub tsev ntiag tug nrog koj tus kheej txhais tes, txhua yam khoom siv tuaj yeem npog nrog cov xim no.
