Cement-based Self-leveling Mortar Construction Technology

Cement-based self-leveling mortar feem ntau yog siv hauv kev tsim kho kom ua tiav qhov chaw tiaj tus thiab theem. Nov yog cov lus qhia ua ntu zus rau kev tsim kho thev naus laus zis koom nrog hauv kev siv cov cement-based self-leveling mortar:

1. Kev Npaj Nto:

• Ntxuav lub substrate: xyuas kom meej tias lub substrate (pob zeb los yog cov flooring uas twb muaj lawm) yog huv si, tsis muaj plua plav, roj, thiab tej yam kab mob.
• Kho Cracks: Sau thiab kho tej kab nrib pleb los yog nto irregularities nyob rau hauv lub substrate.

2. Priming (yog tias xav tau):

• Daim Ntawv Thov Primer: Siv cov primer haum rau lub substrate yog tias xav tau. Primer pab txhim kho adhesion thiab tiv thaiv tus kheej-leveling mortar kom qhuav sai heev.

3. Kev teeb tsa Perimeter Formwork (yog tias xav tau):

• Txhim kho Formwork: Teeb formwork raws thaj tsam ntawm thaj chaw kom muaj tus kheej-leveling mortar. Formwork pab tsim ib thaj tsam ntawm daim ntawv thov.

4. Sib tov tus kheej-Leveling mortar:

• Xaiv Txoj Cai Mix: Xaiv qhov tsim nyog tus kheej-leveling mortar mix raws li daim ntawv thov yuav tsum tau ua.
• Ua raws li Chaw Tsim Tshuaj Cov Lus Qhia: Sib tov cov mortar raws li cov chaw tsim khoom cov lus qhia txog dej-rau-hmoov piv thiab sijhawm sib tov.

5. Pouring tus kheej-Leveling mortar:

• Pib Pouring: Pib ncuav cov hmoov sib tov nws tus kheej-leveling mortar mus rau lub substrate npaj.
• Ua haujlwm hauv ntu: Ua haujlwm hauv cov ntu me kom ntseeg tau tias muaj kev tswj xyuas kom zoo ntawm qhov ntws thiab qib ntawm cov tshuaj khib nyiab.

6. Kev nthuav dav thiab theem:

• Spread evenly: Siv lub ntsuas rake lossis ib lub cuab yeej zoo sib xws los nthuav cov mortar sib npaug ntawm qhov chaw.
• Siv Smoother (Screed): Siv lub smoother los yog screed rau qib ntawm mortar thiab ua tiav cov thickness xav tau.

7. Deearation thiab Smoothing:

• Deaeration: Txhawm rau tshem tawm cov npuas huab cua, siv lub tshuab ua pa lossis lwm yam cuab yeej deaeration. Qhov no yuav pab ua kom tiav ib tug smoother tiav.
• Correct Imperfections: Tshawb xyuas thiab kho txhua qhov tsis zoo lossis qhov tsis sib xws hauv qhov chaw.

8. Kev kho:

• Npog Qhov Nto: Tiv thaiv cov khoom siv tshiab ntawm tus kheej-leveling mortar los ntawm kev ziab sai dhau los ntawm kev npog nws nrog cov ntawv yas lossis cov ntaub ntub dej ntub.
• Ua raws sijhawm Curing: Ua raws li cov chaw tsim khoom cov lus pom zoo txog lub sijhawm kho. Qhov no ua kom muaj dej kom zoo thiab txhim kho lub zog.

9. Kev kov tiav:

• Kev Tshawb Fawb Kawg: Tshawb xyuas qhov kho qhov chaw kom muaj qhov tsis xws luag lossis qhov tsis sib xws.
• Cov Txheej Txheem Ntxiv (yog tias xav tau): Siv cov txheej txheem ntxiv, sealers, lossis ua tiav raws li qhov project specifications.

10. Tshem tawm ntawm Formwork (yog siv):

• Tshem tawm Formwork: Yog tias siv formwork, ua tib zoo tshem nws tom qab tus kheej-leveling mortar tau teem txaus.

11. Flooring Installation (yog muaj):

• Ua raws li qhov yuav tsum tau ua rau Flooring: Ua raws li cov lus qhia tshwj xeeb uas muab los ntawm cov tuam ntxhab hauv pem teb hais txog cov nplaum thiab cov txheej txheem kev teeb tsa.
• Tshawb xyuas cov ntsiab lus noo noo: xyuas kom meej tias cov dej noo ntawm tus kheej-leveling mortar yog nyob rau hauv kev txwv tsis pub ua ntej txhim kho cov ntaub pua tsev.

Cov ntsiab lus tseem ceeb:

• Kub thiab av noo: Ua tib zoo saib xyuas qhov kub thiab av noo thaum lub sij hawm thov thiab kho kom zoo rau kev ua haujlwm zoo.
• Kev Sib xyaw thiab Kev Siv Lub Sijhawm: Tus kheej-leveling mortars feem ntau muaj lub sijhawm ua haujlwm tsawg, yog li nws tseem ceeb heev rau kev sib xyaw thiab siv lawv hauv lub sijhawm teev tseg.
• Thickness Control: Ua raws li cov lus qhia thickness uas tau muab los ntawm cov chaw tsim khoom. Kev hloov kho tej zaum yuav xav tau raws li cov kev cai tshwj xeeb ntawm qhov project.
• Cov Khoom Siv Zoo: Siv cov khoom zoo ntawm tus kheej-leveling mortar thiab ua raws li cov lus qhia tshwj xeeb muab los ntawm cov chaw tsim khoom.
• Kev Ntsuas Kev Nyab Xeeb: Ua raws li cov lus qhia kev nyab xeeb, suav nrog kev siv cov cuab yeej tiv thaiv tus kheej (PPE) thiab ua kom lub qhov cua kom zoo thaum thov.

Nco ntsoov xa mus rau cov ntaub ntawv qhia kev thiab cov txheej txheem muab los ntawm cov chaw tsim khoom ntawm tus kheej-leveling mortar rau cov lus qhia tshwj xeeb thiab cov lus pom zoo. Tsis tas li ntawd, xav txog kev sab laj nrog cov kws tshaj lij kev tsim kho rau cov haujlwm nyuaj lossis yog tias koj ntsib teeb meem thaum lub sijhawm thov.
