Redispersible polymer latex hmoovCov khoom yog cov dej-soluble redispersible hmoov, uas tau muab faib ua ethylene / vinyl acetate copolymer, vinyl acetate / tertiary ethylene carbonate copolymer, acrylic acid copolymer, thiab lwm yam, nrog polyvinyl cawv raws li kev tiv thaiv colloid.Vim muaj peev xwm binding siab thiab cov khoom tshwj xeeb ntawm dispersible polymer hmoov
Ntxiv cov hmoov dispersible polymer rau cov khoom sib koom ua ke tuaj yeem txhim kho nws cov cohesion thiab yooj.
Lub tsev cog khoom mortar yuav tsum muaj adhesion zoo rau lub hauv paus cov ntaub ntawv yuav tsum tau bonded txawm tias nws yog thov heev thinly.Unmodified cement mortars feem ntau tsis sib raug zoo yam tsis muaj pretreatment ntawm lub hauv paus.
Qhov sib ntxiv ntawm redispersible latex hmoov tuaj yeem txhim kho qhov adhesion.Lub saponification tsis kam ntawm redispersible latex hmoov tuaj yeem tswj cov qib ntawm adhesion ntawm mortar tom qab kev sib cuag nrog dej thiab Frost.Cov saponification-resistant polymer tuaj yeem tau txais los ntawm copolymerizing vinyl acetate thiab lwm cov monomers tsim nyog..Siv ethylene ua cov comonomer uas tsis yog-saponifiable los tsim cov ethylene-muaj redispersible latex hmoov tuaj yeem ua tau raws li tag nrho cov kev cai rau cov hmoov latex nyob rau hauv cov nqe lus ntawm kev laus tsis kam thiab hydrolysis tsis kam.
