Redispersible polymer hmoov (RDP) rau mortar cement

Redispersible polymer hmoov (RDP) yog cov dej-soluble hmoov uas tuaj yeem siv los txhim kho cov khoom ntawm mortar thiab cement. RDP yog tsim los ntawm polymerizing yas acetate thiab ethylene nyob rau hauv ib tug aqueous emulsion. Lub resulting emulsion yog ces tsuag qhuav los ua ib tug dawb ntws hmoov.

RDP yog siv nyob rau hauv ntau yam mortar thiab cement khoom xws li:

daim nplaum nplaum

tus kheej leveling mortar

Putty hmoov

tawg muab tub lim

Rwb thaiv tsev mortar

Cement-based plaster

Cementitious Coatings

RDP txhim kho kev ua haujlwm ntawm mortars thiab cements los ntawm:

nce dej tuav

Txhim kho kev ua haujlwm

nce tensile zog

nce khoov zog

txo shrinkage

nce dej tsis kam

nce hluav taws kub

Cov txheej txheem tsim khoom ntawm RDP yog raws li hauv qab no:

Vinyl acetate thiab ethylene yog polymerized nyob rau hauv ib qho aqueous emulsion.

Cov emulsion yog cov tshuaj tsuag qhuav kom tsim cov hmoov dawb ntws.

Cov hmoov yog ces ntim thiab xa mus rau cov neeg siv khoom.

Nov yog qee yam tseem ceeb uas cuam tshuam rau RDP zoo:

Hom polymer siv

polymer molecular hnyav

polymer concentration

Hmoov particle loj

muaj impurities

RDP yog cov khoom siv ntau yam uas tuaj yeem siv los txhim kho kev ua haujlwm ntawm ntau yam khoom siv tshuaj khib thiab cov cement. Los ntawm kev nkag siab txog cov txheej txheem tsim khoom thiab cov ntsiab lus tseem ceeb uas cuam tshuam rau qhov zoo, cov neeg tsim khoom tuaj yeem tsim RDPs uas ua tau raws li cov neeg siv khoom tshwj xeeb.

Nov yog qee qhov txiaj ntsig ntxiv ntawm kev siv RDP hauv mortar thiab cement khoom:

RDP pab txo cov dej xav tau hauv cov tshuaj khib thiab cov cement sib tov. Qhov no tuaj yeem ua rau kev txuag nqi thiab cov txiaj ntsig ib puag ncig.

RDP pab txhim kho kev ua haujlwm ntawm mortar thiab cement sib tov. Qhov no tuaj yeem ua rau kev siv cov khoom yooj yim dua thiab tuaj yeem txo qhov kev pheej hmoo ntawm kev ua yuam kev.

RDP pab ua kom muaj zog thiab ua haujlwm ntev ntawm cov khoom khib nyiab thiab cov cement. Qhov no txuas ntxiv lub neej ntawm cov khoom thiab txo qhov kev xav tau ntawm kev kho.

Zuag qhia tag nrho, RDP yog cov cuab yeej tseem ceeb uas tuaj yeem siv los txhim kho kev ua haujlwm ntawm mortar thiab cement khoom. Los ntawm kev nkag siab txog cov txiaj ntsig ntawm RDP thiab cov yam ntxwv uas cuam tshuam rau nws qhov zoo, cov neeg tsim khoom tuaj yeem txiav txim siab txog kev siv cov khoom los txhim kho lawv cov khoom thiab cov txheej txheem.
