Phab ntsa sab nraud yuav tsum raug cua thiab lub hnub, uas sim seb cov roj hmab puas tiv taus huab cua. Yog li ntawd, kev tsim kho phab ntsa sab nraud yuav tsum tau ua kom nruj heev. Niaj hnub no, peb yuav kawm txog cov txheej txheem thev naus laus zis ntawm kev tsim kho phab ntsa sab nraud. A, ua ntej peb ntxuav cov phab ntsa ntawm theem hauv paus, phab ntsa sab nraud feem ntau yog rau cov teeb meem ntawm theem hauv paus plua plav, hnyav tuaj yeem nce xuab zeb, yog li peb yuav tsum raws li qhov xwm txheej ntawm tsawg dua ntawm theem hauv paus los ntxuav kev tsim kho, tom qab thawj zaug txhuam cov plua plav siv emulsion JW301-20 alkali resistant primer rau kev tsim kho, cov tshuaj pleev no yog vitrified kub txog 23 c, yog qhov nyuaj siab ntawm emulsion. Raws li qhov yuav tsum tau ua ntawm kev kho qhov chaw hauv paus, cov emulsion yog sib xyaw nrog dej. Qhov piv ntawm hmoov rau dej yog 1: 4, thiab qhov piv ntawm xuab zeb rau xuab zeb yog li 1: 2.5. Tom qab ua tiav qhov chaw ntawm lub hauv paus, qhov chaw ntawm lub hauv paus qhuav tag. Ob, ua raws li sab nraub qaum ntawm cov vuas ceramic rau txhuam cov roj hmab, nrog rau cov menyuam dov txhuam cov roj hmab rau cov vuas ceramic nto nyias txheej, xws li qhuav! Txhuam thiab muab tshuaj txhuam! Zoo !! Peb, thiab cement mortar, qhov no yog ib qho tseem ceeb tshaj plaws, feem ntau yog kev paub txog kev tsim kho tus tswv yooj yim yuav tsis yog teeb meem, vim tias lawv nyob ntawm qhov sib piv ntawm cov cement mortar yog qhov tseeb, rau cov cement mortar sib tov degree kuj nkag siab heev, tom qab sib tov cov cement mortar, ncaj qha rau ntawm muaj besmear txhuam zoo saum toj no cov kua nplaum rov qab ntawm cov vuas ceramic vuas ceramic, tau erased. Plaub, qhov kawg yog nyob rau ntawm phab ntsa, vuas ntawm phab ntsa, nrog rau lub rauj me me, txawm tias khob vuas vuas kom ua tiav qhov sib npaug kab rov tav! Txhawb cov vuas nrog ib yam khoom tawv lossis txee kom txog thaum cov dej noo hauv cov cement evaporates. Plaub lub ntsiab lus saum toj no yog cov txheej txheem tsim kho ntawm cov vuas ceramic gum, thiab them sai sai rau cov ntsiab lus!
