Ukusetshenziswa kwe-Redispersible Polymer Powder ku-Joint Filling Mortar

I-polymer latex powder ehlakazeka kabushaimikhiqizo izimpushana eziphinde zihlakazeke ezincibilika emanzini, ezihlukaniswe zibe ama-ethylene/vinyl acetate copolymers, ama-vinyl acetate/tertiary ethylene carbonate copolymers, ama-copolymers e-acrylic acid, njll., ane-polyvinyl alcohol njenge-colloid evikelayo. Ngenxa yomthamo omkhulu wokubopha kanye nezakhiwo ezihlukile zama-polymer powders ahlakazekayo

Ukwengeza i-polymer powder ehlakazeka odakeni lokugcwalisa ngokuhlanganyela kungathuthukisa ukuhlangana kwayo nokuguquguquka.

I-bonding mortar kufanele ibe nokunamathela okuhle kwezinto eziyisisekelo okumele ziboshwe ngisho noma zisetshenziswe kancane kakhulu. Izinsalela zikasimende ezingashintshiwe ngokuvamile azihlanganisi kahle ngaphandle kokulungiswa kusengaphambili kwesisekelo.

Ukwengezwa kwe-latex powder e-redispersible kungathuthukisa ukunamathela. Ukumelana ne-saponification yempushana ye-latex ehlakazeka kabusha kungalawula izinga lokunamathela kodaka ngemva kokuthintana namanzi nesithwathwa. I-polymer engamelana ne-saponification ingatholwa nge-copolymerizing vinyl acetate namanye ama-monomers afanelekile. . Ukusebenzisa i-ethylene njenge-comonomer engeyona i-saponifiable ukwenza izimpushana ze-latex ezigaywa kabusha ezine-ethylene zingahlangabezana nazo zonke izidingo ze-latex powders mayelana nokumelana nokuguga kanye nokumelana ne-hydrolysis.
