Kev cuam tshuam ntawm RDP ntawm tus kheej-leveling mortar

Redispersible polymer hmoov (RDP) feem ntau yog siv los ua ib qho tseem ceeb additive hauv self-leveling mortar formulations. RDP tuaj yeem txhim kho kev ua haujlwm ntawm tus kheej-leveling mortar hauv ntau txoj hauv kev, suav nrog kev txhim kho adhesion, ua kom muaj zog thiab kav ntev, thiab txhim kho kev ua haujlwm. Hauv tsab xov xwm no, peb yuav tshawb txog qhov cuam tshuam ntawm RDP ntawm tus kheej-leveling mortar.

Self-Leveling mortar yog dab tsi?

Self-leveling mortar yog ib hom ntawm cov khoom siv hauv pem teb uas yog siv los tsim ib qho chaw du thiab qib. Nws yog feem ntau siv nyob rau hauv kev lag luam thiab kev lag luam chaw, qhov twg yuav tsum muaj cov tshuaj zoo thiab ruaj khov flooring. Self-leveling mortar feem ntau yog tsim los ntawm cov cement, xuab zeb, thiab additives xws li polymers thiab superplasticizers.

Kev cuam tshuam ntawm RDP ntawm Kev Ntsuas Tus Kheej

1. Txhim kho Adhesion

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv RDP hauv tus kheej-leveling mortar yog txhim kho adhesion. Qhov sib ntxiv ntawm RDP tuaj yeem ua rau kom muaj zog ntawm cov mortar thiab substrate, ua rau kev ua tau zoo tag nrho thiab kav ntev. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum nws tus kheej-leveling mortar yog siv tshaj cov ntaub ntawv hauv pem teb uas twb muaj lawm.

2. Ua kom muaj zog thiab kav ntev

RDP tseem tuaj yeem ua rau muaj zog thiab ua haujlwm ntev ntawm tus kheej-leveling mortar. Qhov sib ntxiv ntawm RDP tuaj yeem txhim kho lub zog flexural, compressive zog, thiab kev puas tsuaj ntawm cov mortar. Qhov no tuaj yeem pab kom ntev lub neej ntawm cov flooring thiab txo qhov xav tau kev kho lossis hloov.

3. Txhim kho kev ua haujlwm

RDP tseem tuaj yeem txhim kho kev ua haujlwm ntawm tus kheej-leveling mortar. Qhov sib ntxiv ntawm RDP tuaj yeem txhim kho cov khoom rheological ntawm mortar, ua kom nws yooj yim rau kev sib tov, twj, thiab siv. Qhov no tuaj yeem txuag lub sijhawm thiab txo qhov kev pheej hmoo ntawm kev ua yuam kev thaum lub sijhawm teeb tsa.

4. Kev tiv thaiv dej zoo dua

RDP tuaj yeem txhim kho cov dej tsis kam ntawm tus kheej-leveling mortar. Qhov sib ntxiv ntawm RDP tuaj yeem txhim kho qhov impermeability ntawm mortar, ua rau nws tiv taus dej thiab lwm yam kua. Qhov no tuaj yeem pab tiv thaiv kev puas tsuaj rau hauv pem teb thiab txo qhov kev pheej hmoo ntawm pwm thiab mildew loj hlob.

5. Txhim kho Flow Properties

RDP tuaj yeem txhim kho cov khoom ntws ntawm tus kheej-leveling mortar. Qhov sib ntxiv ntawm RDP tuaj yeem txhim kho cov dej ntws thiab cov yam ntxwv ntawm cov mortar, tso cai rau nws kom kis tau yooj yim dua thiab tsim kom muaj qhov smoother thiab ntau dua. Qhov no tuaj yeem pab ua kom tiav qhov zoo thiab zoo nkauj hauv pem teb tiav.

6. Txhim kho Freeze-Thaw Resistance

RDP tseem tuaj yeem txhim kho qhov khov-thaw tiv thaiv ntawm tus kheej-leveling mortar. Qhov sib ntxiv ntawm RDP tuaj yeem txhim kho lub peev xwm ntawm cov mortar kom tiv taus qhov kub thiab txias thiab raug rau cov dej noo. Qhov no tuaj yeem pab kom ntev lub neej ntawm cov flooring thiab txo qhov xav tau kev kho lossis hloov.

7. Chemical Resistance zoo dua

RDP tuaj yeem txhim kho cov tshuaj tiv thaiv ntawm tus kheej-leveling mortar. Qhov sib ntxiv ntawm RDP tuaj yeem txhim kho qhov tsis kam ntawm cov tshuaj khib rau cov kua qaub, alkalis, thiab lwm yam tshuaj. Qhov no tuaj yeem pab tiv thaiv kev puas tsuaj rau hauv pem teb thiab txo qhov xav tau kev kho lossis hloov.

Xaus

RDP yog ib qho tseem ceeb ntxiv rau hauv tus kheej-leveling mortar formulations, muab kev txhim kho adhesion, lub zog thiab durability, workability, dej tsis kam, ndlwg zog, khov-thaw tsis kam, thiab tshuaj tiv thaiv. Los ntawm kev xaiv cov qib zoo ntawm RDP thiab optimizing cov formulation rau cov kev siv tshwj xeeb, cov neeg tsim thiab cov neeg cog lus tuaj yeem ua tiav cov kev daws teeb meem zoo thiab ruaj khov. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev ua tau zoo ntawm RDP nyob rau hauv tus kheej-leveling mortar tuaj yeem sib txawv nyob ntawm seb cov qauv tsim thiab ib puag ncig. Nws yog ib qho tseem ceeb uas yuav tau ua hauj lwm nrog tus neeg muag khoom muaj npe nrov thiab ua qhov kev ntsuam xyuas nruj kom paub meej tias tus kheej qib mortar ua tau raws li cov qauv thiab cov kev qhia tshwj xeeb.
