Nyob rau hauv mortar, redispersible polymer hmoov tuaj yeem txhim kho kev tsim kho cov yam ntxwv ntawm roj hmab hmoov, txhim kho cov kua roj hmab hmoov, txhim kho thixotropy thiab sag tsis kam, txhim kho lub zog cohesive ntawm roj hmab hmoov, txhim kho dej-solubility, thiab nce lub sij hawm thaum nws qhib. mus rau lub ntiaj teb sab nraud. nruab nrab. Tom qab cov cement mortar qhuav thiab solidified, nws tuaj yeem ua kom lub zog compressive, ua kom lub zog tensile, txo cov pwm elastic, thiab txhim kho qhov tshwj xeeb. redispersible polymer hmoov muaj zoo zaj duab xis-ua adhesion, thiab nws daim ntawv thov yuav pom nyob rau hauv kev tsim kho thiab kho kom zoo nkauj tej yaam num.
Cov roj hmab roj hmab hmoov latex zaj duab xis muaj cov qauv rub tus kheej, uas tuaj yeem tso tawm lub zog txhawb nqa rau kev sib koom tes nrog cov cement mortar thauj tog rau nkoj. Raws li lub zog sab hauv no, cov cement mortar yog khaws cia feem ntau thiab kev sib koom ua ke ntawm pab pawg cement mortar tau txhim kho. Lub hav zoov ntawm siab elastic polymer txhim kho ductility thiab ductility ntawm cement mortar. Lub hauv paus ntsiab lus ntawm kev ua kom muaj kev ntxhov siab thiab tsis muaj zog compressive yog raws li hauv qab no: Thaum lub zog tawm, cov micro-cracks yuav ncua sij hawm kom txog rau thaum qhov kev ntxhov siab nyob rau hauv qhov chaw nthuav dav vim qhov nce hauv ductility thiab ductility. Ntxiv rau qhov no, cov cheeb tsam interlaced polymer kuj muaj kev cuam tshuam rau cov micro-cracks ua ke los ntawm cov kab nrib pleb. Yog li ntawd, dispersed natural latex hmoov tuaj yeem ua rau muaj kev ntxhov siab thiab tsis muaj txiaj ntsig ntawm cov khoom siv raw. Polymer zaj duab xis nyob rau hauv lub polymer hloov cov ntaub ntawv cement mortar yog ib tug tseem ceeb txaus ntshai rau lub hardened cement mortar. Dispersion ntawm dispersible polymer hmoov plays lwm lub luag hauj lwm ntawm nplooj ntawv, uas yog los txhim kho cov adhesion ntawm raw cov ntaub ntawv nyob rau hauv kev sib cuag.
Feem ntau ntawm cov hmoov polymer dispersible uas tib neeg feem ntau pom hauv kev tsim kho yog cov dawb dawb, txawm tias qee qhov ntxoov ntxoo yuav tshwm sim. Cov tshuaj muaj pes tsawg leeg ntawm redispersible latex hmoov yog tsim los ntawm high polymer epoxy resin preservative (sab hauv thiab sab nraud) txij nkawm colloid tov thiab kuj tus neeg sawv cev. Ntawm lawv, lub siab polymer epoxy resin yog nyob rau hauv txoj hauj lwm tseem ceeb ntawm cov roj hmab hmoov hais thiab yog cov khoom tseem ceeb ntawm dispersible polymer hmoov.
Cov hmoov polymer dispersible tsis xav tau cov dej kais dej hauv kev khaws cia thiab kev thauj mus los, uas tuaj yeem txuag nqi kev thauj mus los ntawm engineering tsev modules thiab ua rau kev thauj mus los yooj yim thiab ceev. Lub redispersible natural latex hmoov tsim los ntawm cov cement mortar Hoobkas muaj lub neej ntev txee thiab tuaj yeem khaws cia rau lub sijhawm ntev yam tsis muaj kev txhawj xeeb txog qhov kub thiab txias txias thiab yooj yim cia. Txhua lub hnab ntawm dispersible polymer hmoov yog qhov me me hauv ntim, lub teeb hauv qhov hnyav, thiab siv tau yooj yim.
