Yuav Ua Li Cas Qhuav Mortar Mix?

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

1. Sau cov khoom siv thiab cov khoom siv:

• Cement: Portland cement feem ntau yog siv los ua mortar mix. Xyuas kom koj muaj hom cement uas tsim nyog rau koj daim ntawv thov (piv txwv li, lub hom phiaj siv cement, masonry cement).
• Xuab zeb: Xaiv cov xuab zeb huv, ntse nrog cov khoom zoo rau cov khoom sib tov.
• Additives: Nyob ntawm daim ntawv thov, tej zaum koj yuav tsum muaj cov additives xws li txiv qaub, plasticizers, los yog lwm yam kev ua tau zoo-txhim kho cov neeg sawv cev.
• Kev ntsuas cov cuab yeej: Siv cov thoob ntsuas, scoops, lossis ntsuas ntsuas kom raug ntsuas cov khoom xyaw qhuav.
• Cov Khoom Siv Sib xyaw: Ib lub nkoj sib xyaw, xws li lub log tsheb, lub thawv khib nyiab, lossis lub nruas sib xyaw, yuav tsum tau muab cov khoom xyaw qhuav kom huv si.

2. Txiav txim siab npaum li cas:

• Txiav txim siab qhov sib npaug ntawm cov cement, xuab zeb, thiab cov khoom ntxiv uas xav tau rau cov khoom sib xyaw uas xav tau. Cov proportions yuav txawv nyob ntawm seb yam xws li hom mortar (xws li, masonry mortar, plaster mortar), xav tau lub zog, thiab daim ntawv thov.
• Feem ntau mortar mix proportions xws li 1: 3 (ib feem cement rau peb seem xuab zeb) los yog 1: 4 (ib feem cement rau plaub seem xuab zeb).

3. Cov khoom xyaw qhuav:

• Ntsuas cov khoom tsim nyog ntawm cov cement thiab xuab zeb raws li qhov kev xaiv proportions.
• Yog tias siv cov tshuaj ntxiv, ntsuas thiab ntxiv rau cov khoom sib xyaw qhuav raws li cov chaw tsim khoom pom zoo.
• Muab cov khoom xyaw qhuav rau hauv lub nkoj sib tov thiab siv lub duav lossis cov cuab yeej sib xyaw kom sib xyaw kom zoo. Xyuas kom muaj kev faib tawm ntawm cov khoom sib xws kom ua tiav cov khoom sib xyaw ua ke.

4. Khaws cov khoom qhuav qhuav:

• Thaum cov khoom xyaw qhuav tau sib xyaw kom zoo, hloov cov tshuaj khib nyiab qhuav rau hauv lub thawv huv, qhuav, xws li lub thoob yas los yog lub hnab.
• Kaw lub thawv kom nruj kom tsis txhob ya raws nkag thiab kis kab mob. Khaws cov khoom sib xyaw qhuav rau hauv qhov chaw txias, qhuav kom deb ntawm tshav ntuj ncaj qha thiab ya raws kom txog thaum npaj siv.

5. Ua kom muaj dej:

• Thaum npaj siv cov tshuaj khib nyiab qhuav, hloov qhov xav tau kom muaj nuj nqis rau hauv lub nkoj sib tov huv ntawm qhov chaw tsim kho.
• Maj mam ntxiv dej mus rau qhov sib tov qhuav thaum sib tov tas li nrog lub duav lossis cov cuab yeej sib tov.
• Ntxiv dej thiab sib tov kom txog thaum lub mortar ncav cuag qhov xav tau sib xws, feem ntau yog ib qho yooj yim, ua haujlwm tau zoo nrog adhesion thiab cohesion.
• Tsis txhob ntxiv dej ntau dhau, vim qhov no tuaj yeem ua rau cov mortar tsis muaj zog thiab txo qis kev ua haujlwm.

6. Kev siv thiab kev siv:

• Thaum cov mortar sib tov rau qhov xav tau sib xws, nws yog npaj rau siv nyob rau hauv ntau yam kev siv, xws li bricklaying, blocklaying, plastering, los yog taw tes.
• Siv cov mortar rau hauv lub substrate npaj siv cov tswv yim tsim nyog thiab cov cuab yeej, kom muaj kev sib raug zoo thiab kev sib raug zoo ntawm cov masonry units.

Los ntawm kev ua raws li cov kauj ruam no, koj tuaj yeem tsim cov khoom zoo qhuav mortar mix haum rau ntau yam kev tsim kho. Kev hloov kho rau qhov proportions thiab additives tuaj yeem ua raws li cov kev thov tshwj xeeb thiab cov qauv kev ua haujlwm.
