1. Kev npaj cov ntaub ntawv
Cov ntaub ntawv hauv qab no yuav tsum tau npaj ua ntej kev sib xyaw ntawm mortar: cement, xuab zeb, dej thiab cov khoom siv sib xyaw.
Qhov thib ob, qhov sib tov sib xyaw
Qhov laj thawj ntawm qhov sib piv ntawm mortar plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm tom qab, feem ntau hais lus, qhov piv ntawm cov cement mortar yog 1: 3, thaum qhov sib piv ntawm gypsum mortar yog 1: 2.
3. Xaiv cov khoom siv nplawm
Thaum nqa tawm kev sib tov sib xyaw, phau ntawv lossis cov khoom siv hluav taws xob feem ntau yog siv, ntawm cov khoom siv hluav taws xob tuaj yeem txhim kho kev ua haujlwm.
Plaub, nplawm cov kauj ruam
1. Muab cov cement rau hauv lub thawv huv;
2. Ntxiv cov xuab zeb maj mam, nplawm tas li;
3. Ntxiv ib qho dej rau ib homogeneous, tsis muaj particle-dawb sib tov;
4. Do kom txog thaum sib tov, tsis muaj lumps, xoob lub xeev;
5. Nres lub tshuab nplawm kom tag nrho cov khoom sib tov nyob ib puag ncig.
5. Kev txawj ntse
1. Thaum lub mortar yog nplawm, cov khoom yuav tsum tau maj mam ntxiv, thiab ib feem ntxiv yog ntxiv tom qab stirring tusyees, thiaj li tsis txhob cov khoom pov tseg thiab tsis sib npaug.
2. Nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas qhov tsim nyog ntawm cov dej ntxiv kom tsis txhob sib xyaw ua kom nyias nyias thiab cuam tshuam rau kev tsim kho.
3. Thaum siv lub tshuab tov khoom tes, koj yuav tsum tau ua kom muaj zog thiab sib npaug kom tsis txhob sib tov tsis sib xws.
4. Thaum siv lub tshuab hluav taws xob sib tov, nws yuav tsum tau muab sau tseg tias lub tshuab tov khoom yuav tsum tau ua raws li qhov yuav tsum tau ua hauv phau ntawv qhia kom muaj kev nyab xeeb ntawm tus kheej thiab kev ua haujlwm zoo ntawm cov khoom siv.
6. Kev ceev faj txog kev nyab xeeb
1. Thaum sib xyaw cov ntaub ntawv, koj yuav tsum hnav cov khoom siv tiv thaiv xws li lub qhov ncauj qhov ntswg thiab hnab looj tes kom tsis txhob nqus plua plav thiab cov ntaub ntawv lo rau ntawm koj daim tawv nqaij.
2. Tsis txhob kov cov cuab yeej stirrer ua haujlwm nrog koj txhais tes kom tsis txhob raug mob.
3. Tshem tawm lub hwj chim ua ntej siv lub tshuab hluav taws xob sib tov kom tsis txhob muaj xwm txheej.
