• Ua kom muaj kev nyab xeeb ib puag ncig thiab kev nyiam huv. Cov xim pleev xim rau yog ua pa thiab muaj cov dej noo tiv taus. Qhov no tso cai rau kev ntub ntub thiab pab tswj hwm cov av noo thiab ua kom muaj huab cua zoo nyob hauv chav;
• Zoo nkauj tsos. Cov xim muaj nyob rau hauv ntau qhov ci qhov tseem ceeb xws li 0 txog 100. Qhov ntsuas siab dua, qhov ci ntau dua qhov saum npoo yuav yog thaum pleev xim. Qhov no tso cai rau koj rov kho chav thiab muab nws zoo nkauj zoo nkauj;
• Kev tiv thaiv tshav kub thiab kev nyab xeeb ntawm hluav taws. Cov xim muaj peev xwm tiv taus raug rau qhov kub siab, ua kom tsis muaj kuab lom thiab tsis muaj tshuaj lom. Qhov no tso cai rau koj siv nws ua kom tiav txhua hom chaw thiab ua haujlwm sab nraum zoov yam tsis muaj kev txwv;
• Kev ziab sai thiab yooj yim thov. Lub sijhawm nws yuav siv rau cov xim pleev xim kom qhuav tas li nyob ntawm lub xeev ib puag ncig. Hauv chav sov, cov xim qhuav hauv 2 teev. Kev ywj pheej thiab kev ua siab zoo ntawm cov emulsion ua kom yooj yim los siv cov khoom siv rau phab ntsa thiab tshem tawm kev sib kis thiab tsim cov pob txha.

Qhov tsis zoo ntawm cov kua nplaum emulsions suav nrog qhov xav tau ua ntej kho cov phab ntsa nrog cov primer. Yog tias qhov no tsis ua tiav, tom qab ntawd muaj qhov tshwm sim siab ntawm qhov pom ntawm cov pwm, pwm thiab kab mob. Qhov no yog vim qhov tseeb tias cov yas yog ib puag ncig zoo rau cov kab mob.

Saib

Cov xim pleev xim tau nthuav tawm ntawm kev lag luam niaj hnub tsim hauv ntau yam. Emulsions sib txawv hauv kev muaj pes tsawg leeg, kev ua tau zoo thiab qhov tsos. Rau kev ua haujlwm sab hauv, muaj cov hauv qab no ntawm lawv:

Polyvinyl acetate hmoov Lawv paub zoo dua nyob rau hauv lub npe ntawm cov dej-raws li emulsion thiab dej-dispersion daws. Cov emulsion yog ua los ntawm PVA siv cov kua nplaum, thiab vim tsis muaj cov kuab tshuaj nyob hauv nws cov muaj pes tsawg leeg, cov xim tsis muaj ntxhiab. Qhov sib txawv ntawm qhov ua tau zoo heev, tsis muaj viscosity, tuaj yeem tshem tawm tau yooj yim los ntawm txhais tes thiab khaub ncaws. Tom qab ziab, nws muaj cov nyhuv chalky me ntsis, yog li nws tau pom zoo rau siv tsuas yog pleev xim rau lub qab nthab lossis nyuaj rau mus txog qhov chaw hauv qhov chaw sov.
