Redispersible polymer hmoov yog non-toxic thiab environmentally friendly.Nws yog ib qho tseem ceeb ntxiv rau cov khoom siv hauv tsev tshiab.Ntxiv redispersible polymer hmoov rau hauv mortar hloov lub pore qauv ntawm lub mortar, txo qhov ceev ntawm lub mortar, txhim khu lub internal cohesion ntawm lub mortar, thiab txhim kho lub peev xwm nqus dej ntawm lub mortar.;Ntxiv redispersible polymer hmoov rau lub mortar tsub kom lub freeze-thaw kuj ntawm lub mortar;qhov zoo cohesiveness ntawm redispersible polymer hmoov ua rau lub mortar kuj muaj zoo cohesiveness, tshwj xeeb tshaj yog rau kev sib koom mortar., zoo heev txhim kho kev ua tau zoo ntawm mortar;siv cov hmoov polymer los hloov cov cement mortar tuaj yeem tsim cov hmoov qhuav mortar nrog cov haujlwm sib txawv, muab kev lag luam dav dav rau kev lag luam ntawm mortar.Nws tuaj yeem tsim cov kev cai zoo rau kev siv cov thev naus laus zis tshiab thiab cov khoom siv, ua raws li kev tswj hwm nruj, txhim kho txoj kev tsim kho, thiab ua kom ntseeg tau qhov project zoo.
Lub luag hauj lwm ntawm redispersible polymer hmoov nyob rau hauv mortar:
1 Txhim kho lub zog compressive thiab flexural zog ntawm mortar.
2 Qhov sib ntxiv ntawm cov hmoov polymer ua rau kom qhov elongation ntawm cov tshuaj khib, yog li txhim kho qhov cuam tshuam ntawm cov tshuaj khib nyiab, thiab tseem ua rau cov mortar nrog kev ntxhov siab zoo.
3 Txhim kho qhov kev sib txuas ntawm mortar.Lub tshuab sib txuas yog ua raws li qhov adsorption thiab diffusion ntawm macromolecules ntawm cov nplaum nplaum.Nyob rau tib lub sijhawm, cov hmoov polymer muaj qee yam permeability thiab tag nrho infiltrates saum npoo ntawm cov khoom siv hauv paus nrog cellulose ether, kom cov khoom nto ntawm lub hauv paus thiab cov plaster tshiab nyob ze, yog li txhim kho Adsorption zoo heev ua rau nws cov kev ua tau zoo.
4 Txo cov elastic modulus ntawm mortar, txhim kho lub peev xwm deformation thiab txo qhov tshwm sim tawg.
5 Txhim kho qhov hnav tsis kam ntawm mortar.Kev txhim kho ntawm kev hnav tsis kam yog feem ntau yog vim muaj qee yam ntawm cov kua nplaum rau ntawm qhov chaw ntawm lub mortar.Cov kua nplaum hmoov ua raws li daim ntawv cog lus, thiab cov qauv omentum tsim los ntawm cov kua nplaum hmoov tuaj yeem dhau los ntawm qhov thiab cov kab nrib pleb hauv cov cement mortar.Txhim kho kev sib raug zoo ntawm cov khoom siv hauv paus thiab cov khoom siv cement hydration, yog li ua kom hnav tsis kam.
6 Muab lub mortar zoo heev alkali tsis kam
Resin polymer hmoov muaj cov ntxhiab tsw zoo, tsis yog ib puag ncig tus phooj ywg, thiab pheej yig, tab sis nws cov dej nqus tsis kam, lub zog, thiab lwm yam khoom yog pom tseeb tsis zoo rau cov khoom siv rov ua dua tshiab.Yog li ntawd, tom qab ib qho kev sib piv, redispersible polymer hmoov yog ntau haum rau siv nyob rau hauv mortar.
