Koj Ua Li Cas Thiaj Ua Tau Cov Hmoov Qhuav?

Kev ua cov hmoov av qhuav yog kev sib xyaw cov khoom xyaw qhuav tshwj xeeb, suav nrog cov cement, xuab zeb, thiab cov khoom ntxiv, los tsim cov khoom sib xyaw uas tuaj yeem khaws cia thiab ua haujlwm nrog dej ntawm qhov chaw tsim kho. Nov yog cov lus qhia dav dav rau kev ua cov hmoov av qhuav:

1. Sau Cov Khoom Siv thiab Khoom Siv:

• Cement: Feem ntau siv cov cement Portland los ua cov mortar sib tov. Xyuas kom tseeb tias koj muaj hom cement uas tsim nyog rau koj daim ntawv thov (piv txwv li, cement dav dav, cement masonry).
• Xuab Zeb: Xaiv cov xuab zeb huv si, ntse nrog cov khoom me me uas zoo rau kev sib tov mortar.
• Cov Khoom Ntxiv: Nyob ntawm daim ntawv thov, koj yuav tsum suav nrog cov khoom ntxiv xws li txiv qaub ntsuab, cov khoom yas, lossis lwm yam khoom siv txhim kho kev ua tau zoo.
• Cov Cuab Yeej Ntsuas: Siv cov thoob ntsuas, cov diav ntsuas, lossis cov nplai ntsuas kom raug cov khoom xyaw qhuav.
• Cov Khoom Siv Sib Tov: Xav tau lub thawv sib tov, xws li lub laub laub, lub thawv xuab zeb, lossis lub nruas sib tov, los sib tov cov khoom qhuav kom huv si.

2. Txheeb xyuas qhov sib piv:

• Txheeb xyuas qhov sib piv ntawm cov cement, xuab zeb, thiab cov khoom ntxiv uas xav tau rau cov mortar sib xyaw uas xav tau. Qhov sib piv yuav txawv nyob ntawm seb hom mortar (piv txwv li, masonry mortar, plaster mortar), lub zog uas xav tau, thiab qhov yuav tsum tau siv.
• Cov feem sib xyaw ua ke ntawm cov mortar muaj xws li 1:3 (ib feem cement rau peb feem xuab zeb) lossis 1:4 (ib feem cement rau plaub feem xuab zeb).

3. Sib tov cov khoom xyaw qhuav:

• Ntsuas cov cement thiab xuab zeb kom raug raws li qhov sib piv uas tau xaiv.
• Yog tias siv cov khoom ntxiv, ntsuas thiab ntxiv rau hauv cov khoom sib tov qhuav raws li cov lus qhia ntawm cov chaw tsim khoom.
• Muab cov khoom qhuav sib xyaw rau hauv lub thawv sib tov thiab siv lub diav lossis lub cuab yeej sib tov los sib tov kom huv si. Xyuas kom cov khoom sib xyaw sib npaug kom tau cov hmoov sib tov sib xws.

4. Khaws cov khoom qhuav cia:

• Thaum cov khoom xyaw qhuav sib tov tag lawm, muab cov hmoov av qhuav tso rau hauv lub thawv huv thiab qhuav, xws li lub thoob yas lossis lub hnab yas.
• Kaw lub thawv kom nruj kom tsis txhob muaj dej noo nkag thiab ua rau muaj kuab paug. Khaws cov khoom qhuav rau hauv qhov chaw txias, qhuav kom deb ntawm tshav ntuj ncaj qha thiab noo noo kom txog thaum npaj siv tau.

5. Ua kom dej kub:

• Thaum npaj siv cov hmoov av qhuav, muab cov khoom xav tau rau hauv lub thawv sib tov huv si ntawm qhov chaw tsim kho.
• Maj mam ntxiv dej rau hauv cov khoom qhuav thaum sib tov tas li nrog lub diav lossis cov cuab yeej sib tov.
• Txuas ntxiv ntxiv dej thiab sib tov kom txog thaum cov tshuaj khib nyiab mus txog qhov sib xws raws li xav tau, feem ntau yog cov nplaum du, ua haujlwm tau zoo nrog kev nplaum zoo thiab sib zog.
• Tsis txhob ntxiv dej ntau dhau, vim qhov no yuav ua rau cov mortar tsis muaj zog thiab ua haujlwm tsis zoo.

6. Siv thiab Daim Ntawv Thov:

• Thaum cov mortar sib xyaw kom txog thaum nws sib xws, nws npaj txhij rau kev siv rau hauv ntau yam kev siv hauv kev tsim kho, xws li kev ua cib, kev ua blocklaying, kev ua plastering, lossis kev taw qhia.
• Siv cov mortar rau ntawm cov substrate uas tau npaj tseg siv cov txheej txheem thiab cov cuab yeej tsim nyog, kom ntseeg tau tias muaj kev sib txuas thiab sib dhos zoo ntawm cov masonry units.

Thaum ua raws li cov kauj ruam no, koj tuaj yeem tsim cov hmoov av qhuav zoo uas haum rau ntau yam haujlwm tsim kho. Kev hloov kho rau qhov sib piv thiab cov khoom ntxiv tuaj yeem ua tau raws li qhov xav tau ntawm kev siv thiab cov qauv kev ua tau zoo.
