Gypsum-based self-leveling compound mortar yog ib yam ntawm cov flooring underlayment uas yog siv los tsim du thiab theem ntawm qhov chaw hauv kev npaj rau kev teeb tsa ntawm cov ntaub pua tsev xws li vuas, yas, ntaub pua plag, lossis ntoo tawv. Qhov mortar no yog tsim los rau qib tsis sib luag lossis sloping substrates thiab muab lub tiaj tiaj thiab txawm tias lub hauv paus rau cov khoom siv hauv pem teb zaum kawg. Nov yog cov yam ntxwv tseem ceeb thiab cov yam ntxwv ntawm gypsum-based self-leveling compound mortar:

1. Kev sib xyaw:

• Gypsum: Lub ntsiab tivthaiv yog gypsum (calcium sulfate) nyob rau hauv daim ntawv ntawm hmoov. Gypsum yog tov nrog lwm yam additives los txhim kho cov khoom xws li khiav, teem sij hawm, thiab lub zog.

2. Khoom:

• Self-Leveling: Lub mortar yog tsim los kom muaj tus kheej-leveling zog, tso cai rau nws ntws thiab nyob rau hauv ib tug du, tiaj tus nto yam tsis tas yuav tsum tau ntau troweling.
• High Fluidity: Gypsum-based self-leveling compounds muaj fluidity siab, ua rau lawv ntws tau yooj yim thiab ncav mus rau hauv qhov chaw qis, sau cov voids thiab tsim kom muaj theem saum npoo.
• Kev teeb tsa nrawm: Muaj ntau cov qauv tsim los teeb tsa sai, tso cai rau kev teeb tsa sai dua.

3. Kev siv:

• Kev Npaj Subfloor: Gypsum-based self-leveling compounds yog siv los npaj cov subfloor hauv vaj tse, kev lag luam, thiab kev lag luam. Lawv yog siv rau pob zeb, plywood, los yog lwm yam substrates.
• Kev siv sab hauv: Tsim nyog rau cov ntawv thov sab hauv uas cov xwm txheej tswj tau thiab tsis muaj dej noo tsawg.

4. Cov txiaj ntsig:

• Leveling: Qhov txiaj ntsig tseem ceeb yog qhov muaj peev xwm ua kom tsis sib luag lossis qhov chaw sloping, muab lub hauv paus du thiab txawm tias lub hauv paus rau kev teeb tsa hauv pem teb tom ntej.
• Fast Installation: Rapid-set formulations tso cai rau kev teeb tsa sai thiab nrawm dua mus rau theem tom ntej ntawm kev tsim kho lossis kev kho dua tshiab.
• Minimizes Pem Teb Npaj Lub Sijhawm: Txo qhov xav tau ntawm kev npaj hauv pem teb dav dav, ua rau nws muaj txiaj ntsig zoo.

5. Kev teeb tsa:

• Kev Npaj Nto: Ntxuav lub substrate kom huv si, tshem tawm cov plua plav, khib nyiab, thiab cov kab mob. Kho tej kab nrib pleb los yog imperfections.
• Priming (yog tias xav tau): Siv cov primer rau lub substrate los txhim kho adhesion thiab tswj cov absorbency ntawm qhov chaw.
• Mixing: Sib tov cov gypsum-based self-leveling compound raws li cov chaw tsim khoom cov lus qhia. Xyuas kom tus du thiab pob-dawb sib xws.
• Pouring thiab Spreading: Muab cov khoom sib xyaw rau hauv lub substrate thiab kis nws tusyees siv lub ntsuas ntsuas los yog cov cuab yeej zoo sib xws. Tus kheej-leveling zog yuav pab faib cov compound uniformly.
• Deaeration: Siv cov menyuam ntxaib kom tshem tawm cov npuas npuas thiab ua kom lub ntsej muag du.
• Kev teeb tsa thiab Kho: Tso cai rau cov khoom sib xyaw kom teeb tsa thiab kho raws li lub sijhawm teev tseg los ntawm cov chaw tsim khoom.

6. Kev txiav txim siab:

• Moisture Sensitivity: Gypsum-based compounds rhiab heev rau cov dej noo, yog li lawv yuav tsis haum rau thaj chaw uas raug dej ntev.
• Thickness Limitations: Qee cov formulations tej zaum yuav muaj cov thickness txwv, thiab cov khaubncaws sab nraud povtseg ntxiv yuav xav tau rau cov ntaub ntawv tuab.
• Compatibility nrog Pem Teb Npog: Xyuas kom muaj kev sib haum xeeb nrog cov hom tshwj xeeb ntawm cov ntaub pua tsev uas yuav raug ntsia rau ntawm tus kheej-leveling compound.

Gypsum-based self-leveling compound mortar yog ntau yam kev daws teeb meem rau kev ua tiav qib thiab du subfloors hauv ntau daim ntawv thov. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum ua tib zoo ua raws li cov chaw tsim khoom cov lus qhia thiab cov lus pom zoo rau kev teeb tsa kom zoo thiab xav txog cov kev cai tshwj xeeb ntawm cov txheej txheem hauv pem teb uas yuav siv rau hauv qhov sib xyaw.
