Cov stucco tau qhuav tag tom qab ib lossis ob hnub.

Plaster ntawm paris feem ntau siv hauv kev tshem tawm cov tshuaj pleev ib ce tsis zoo ntawm phab ntsa thiab qab nthab . Kev sib xyaw ntawm alabaster yog qhov kev xaiv zoo tshaj plaws rau kev pleev xim rau hauv cov chav uas muaj cov av ib puag ncig ib puag ncig, vim tias gypsum nquag nqus dej ntau dhau. Tsis tas li ntawd, alabaster mortar tau siv hauv kev ua haujlwm kho kom kaw qhov tawg. Nrog nws txoj kev pab, koj tuaj yeem npaj cov tshuaj plaster rau phab ntsa.

Txhawm rau kaw lub qhov, koj yuav tsum xub tshem qhov tawg uas tau tsim thiab ua rau qhov chaw no nrog cov tshuaj pleev ua ntej siv cov xim txhuam . Tom qab ntawd koj tuaj yeem rub hauv cov tshuaj npaj siv spatula. Tom qab ntawd muab daim kab xev nplaum tus kheej-serpyanka tso rau ntawm lub qhov.

Dilution rau nchuav rau hauv pwm

Yog tias gypsum xav tau nchuav rau hauv cov pwm, tom qab ntawd txhawm rau kom cov khoom siv ua lub cev xav tau, nws yog qhov yuav tsum tau ua raws li qee feem hauv kev tsim cov tshuaj. Nws raug nquahu kom sib tov gypsum nrog kua hauv qhov sib piv ntawm 7: 10 . Qhov piv txwv no tso cai rau koj kom tau txais qhov sib xws ua kua, uas yog qhov tshwj xeeb tshaj yog thaum gypsum tawv hauv daim ntawv xav tau. Txawm li cas los xij, cov khoom lag luam tuaj yeem tawg heev, yog li ob diav ntawm PVA kua nplaum yuav tsum tau ntxiv rau qhov muaj pes tsawg leeg.

Kev teeb tsa nrawm ntawm gypsum ncaj qha nyob ntawm kev sib tsoo, muaj cov khoom tsis huv hauv cov muaj pes tsawg leeg, cov chaw tsim khoom thiab qhov sib ntxiv ntawm cov dej ntxiv . Raws li cov gypsum hardens, nws loj hlob me me, thaum tso me me ntawm cov cua sov. Cov cuab yeej muaj txiaj ntsig no pab ua kom puv txhua kab noj hniav.

Nrog dej

Yog tias koj xav tau cov tshuaj gypsum muaj zog, nws raug nquahu kom dilute cov hmoov nrog dej hauv qhov sib piv ntawm 2: 1. Yog tias koj xav tau cov tshuaj nruab nrab-muag, siv 1 liter dej rau 1.5 kg ntawm gypsum hmoov.

Nrog slaked txiv qaub

Thaum sib tov gypsum nrog cov kua qaub, nws yog ib qho tseem ceeb kom soj ntsuam qhov sib piv kom raug, txwv tsis pub cov phab ntsa npog yuav ua kom pom kev zoo (yog tias qhov ntsuas tsis txaus). Nrog ntau dhau, cov npuas yuav pib tsim rau saum npoo, thiab cov gypsum yuav poob tawm ntawm phab ntsa. Qhov kev faib ua feem yog xaiv raws thaj chaw uas yuav ua tiav. Rau txhua 2.5 m2, koj yuav tsum tau noj 0.5 kg ntawm txiv qaub thiab dilute qhov sib xyaw hauv 0.75 liv dej.

Ua ntej pib daim ntawv thov, kev saib xyuas yuav tsum tau ua kom ntseeg tau tias cov nplaim tau ua kom huv ntawm ntau yam av thiab txheej txheej qub. Yog tias tsim nyog, siv plaster thiab primer rau saum npoo tsis sib xws.

Slaked txiv qaub ua rau kom muaj zog ntawm cov txheej txheej gypsum, txawm tias nyob hauv cov av qis hauv chav.

Kev pom zoo

Rau kev ua haujlwm me me, nws yog qhov zoo dua los siv cov hlau tsis muaj hlau los yog cov tawv ntoo. Yog tias txheej txheej muaj thaj tsam loj, nws yog qhov zoo dua los siv lub tshuab hluav taws xob tov nrog cov khoom tshwj xeeb.
