Gypsum troweling compound yog ntau yam khoom siv nyob rau hauv kev tsim kho kev lag luam rau smoothing thiab finishing nto.Los ntawm kev koom nrog Hydroxypropyl Methylcellulose (HPMC) rau hauv kev sib xyaw, koj tuaj yeem txhim kho kev ua haujlwm thiab cov khoom nplaum ntawm cov khoom sib xyaw.Hauv tsab xov xwm no, peb yuav muab cov lus qhia ntxaws ntxaws txog yuav ua li cas ua gypsum troweling compound nrog HPMC, suav nrog cov kev faib tshwj xeeb rau cov txiaj ntsig zoo.
Cov khoom xyaw:
Gypsum hmoov
HPMC hmoov
Dej
Khoom siv:
Cov cuab yeej ntsuas
Lub thawv sib tov
Stirring stick los yog tov khoom
Cov khoom siv tiv thaiv tus kheej (PPE)
Kauj Ruam 1: Txiav txim siab tus nqi ntawm Gypsum Powder Ntsuas qhov xav tau ntawm gypsum hmoov rau koj qhov project.Qhov piv ntawm gypsum hmoov rau HPMC hmoov yuav txawv nyob ntawm seb qhov xav tau sib xws thiab cov chaw tsim khoom cov lus pom zoo.Xa mus rau cov lus qhia ntim rau qhov tseeb piv.
Kauj Ruam 2: Muab Gypsum thiab HPMC Powders rau hauv lub thawv huv thiab qhuav sib tov, ntxiv qhov ntsuas ntawm gypsum hmoov.
Kauj Ruam 3: Ntxiv HPMC Powder Ntsuas qhov tsim nyog ntawm HPMC hmoov raws li gypsum hmoov hnyav.Qhov pom zoo concentration feem ntau yog los ntawm 0.1% mus rau 0.5%.Nrog rau cov lus qhia ntim rau qhov kev faib ua feem.
Kauj Ruam 4: Sib tov cov hmoov Ua kom zoo sib xyaw cov gypsum thiab HPMC hmoov ua ke kom txog thaum lawv ua ke zoo.Cov kauj ruam no ua kom ntseeg tau tias HPMC hmoov yog sib npaug hauv cov gypsum.
Kauj Ruam 5: Maj mam Ntxiv Dej Maj mam ntxiv dej rau qhov sib tov thaum nplawm tas li.Pib nrog me me ntawm cov dej thiab maj mam nce mus txog thaum qhov kev xav tau sib xws.Qhov sib xws yuav tsum yog du thiab yooj yim kis tau tab sis tsis dhau los dhau.Tus nqi npaum li cas ntawm cov dej yuav tsum tau sib txawv nyob ntawm seb cov hmoov sib piv thiab cov txiaj ntsig xav tau.
Kauj Ruam 6: Khaws Cia Ntxiv Ntxiv qhov sib tov kom txog thaum koj muaj qhov sib tov, tsis muaj troweling compound.Cov kauj ruam no yog ib qho tseem ceeb los xyuas kom meej tias HPMC hydrates kom zoo thiab tshem tawm ib qho clumps lossis cua npuas.
Kauj Ruam 7: Cia Dej Cia cov dej sib tov zaum ob peb feeb kom tso cai rau HPMC kom hydrate tag nrho.Cov txheej txheem hydration no txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom sib txuas, yog li txhim kho nws cov kev ua tau zoo thaum siv.
Kauj Ruam 8: Daim Ntawv Thov Txheej Txheem Thaum cov khoom sib xyaw tau hydrated, nws yog npaj rau kev siv.Thov nws mus rau qhov chaw uas xav tau siv lub trowel lossis putty riam.Tshem tawm txhua qhov tsis zoo thiab ua raws li cov lus qhia kom qhuav los ntawm gypsum hmoov chaw tsim khoom.
Nco tseg: Nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov chaw tsim khoom cov lus qhia rau ob qho tib si gypsum hmoov thiab HPMC hmoov, vim tias lawv yuav muaj cov lus qhia tshwj xeeb rau kev sib xyaw sib xyaw thiab lub sijhawm ziab.
Los ntawm kev koom nrog HPMC rau hauv koj cov gypsum troweling compound, koj tuaj yeem txhim kho nws cov khoom, ua kom yooj yim rau kev ua haujlwm nrog thiab txhim kho nws cov adhesion.Qhov sib npaug ntawm gypsum hmoov thiab HPMC yuav nyob ntawm koj qhov project thiab cov chaw tsim khoom cov lus pom zoo.Cov lus qhia ib kauj ruam dhau los no muab lub hauv paus rau kev tsim cov khoom zoo gypsum troweling compound nrog HPMC, ua kom muaj kev sib tw thiab kev ua tiav rau koj cov haujlwm tsim kho.Nco ntsoov hnav cov khoom tiv thaiv tus kheej (PPE) thiab ua raws li kev tiv thaiv kev nyab xeeb thaum ua haujlwm nrog cov hmoov thiab tshuaj.
