Hmoov Polymer uas yaj tau dua tshiab (RDP)
Hmoov Polymer uas yaj tau dua (RDP)
CAS: 24937-78-8
Hmoov Polymer uas yaj tau dua tshiab(RDP) yog tshuaj tsuag qhuav redispersible emulsion latex hmoov, tsim rau kev lag luam kev tsim kho kom txhim kho cov yam ntxwv ntawm cov mortar qhuav sib xyaw, muaj peev xwm rov ua dua hauv dej thiab cuam tshuam nrog cov khoom hydrate ntawm cement / gypsum thiab stuffing, tsim cov composite membrane nrog lub zog zoo mechanics.
Nws txhim kho cov yam ntxwv tseem ceeb ntawm kev siv cov mortar qhuav, xws li lub sijhawm qhib ntev dua, lo rau cov khoom siv nyuaj dua, siv dej tsawg dua, zoo dua kev sib txhuam thiab kev cuam tshuam.
Tom qab txau kom qhuav, VAE emulsion raug hloov mus ua hmoov dawb uas yog copolymer ntawm ethyl thiab vinyl acetate. Nws yog dawb-ntws thiab yooj yim rau emulsify. Thaum dispersed hauv dej, nws tsim ib qho emulsion ruaj khov. Muaj cov yam ntxwv ib txwm muaj ntawm VAE emulsion, cov hmoov dawb-ntws no muab kev yooj yim dua hauv kev tuav thiab khaws cia. Nws tuaj yeem siv los ntawm kev sib xyaw nrog lwm cov ntaub ntawv zoo li hmoov, xws li cement, xuab zeb thiab lwm yam khoom sib xyaw ua ke, thiab nws kuj tuaj yeem siv ua tus binder hauv cov ntaub ntawv tsim kho thiab cov nplaum.
Hmoov Polymer Redispersible (RDP) yaj hauv dej yooj yim thiab sai sai ua cov emulsion. Nws txhim kho cov khoom siv tseem ceeb ntawm cov mortars qhuav, qhib lub sijhawm ntev dua, lo rau cov substrates nyuaj, siv dej tsawg dua, zoo dua kev puas tsuaj thiab kev cuam tshuam.
