Mu matope, redispersible polima ufa akhoza kusintha zomangamanga zomangamanga makhalidwe a mphira ufa, kusintha fluidity wa mphira ufa, kusintha thixotropy ndi sag kukana, kusintha n`zogwirizana mphamvu ya mphira ufa, kusintha madzi solubility, ndi kuonjezera nthawi pamene anatsegula. kudziko lakunja. pakati. Simenti ikaumitsidwa ndikukhazikika, imatha kukulitsa mphamvu yopondereza, kukulitsa mphamvu yamphamvu, kuchepetsa nkhungu zotanuka, ndikuwongolera mawonekedwe ake. redispersible polima ufa uli ndi zomatira zabwino zopanga filimu, ndipo kugwiritsa ntchito kwake kumawonedwa pama projekiti omanga ndi zokongoletsera.
Filimu ya utomoni ya ufa wa latex ili ndi mawonekedwe odzikoka okha, omwe amatha kumasula mphamvu yothandizira kuti igwirizane ndi nangula wamatope a simenti. Malingana ndi mphamvu zamkati izi, matope a simenti amasungidwa mwachizoloŵezi ndipo kugwirizanitsa gulu la simenti la simenti kumakhala bwino. Kukhalapo kwa polima zotanuka kwambiri kumapangitsa kuti ductility ndi ductility wa matope simenti. Mfundo yowonjezera kupsinjika kwa zokolola ndi mphamvu zopanda mphamvu zowonongeka ndi izi: Pamene mphamvu imatulutsidwa, ma micro-cracks adzachedwetsa nthawi mpaka kupanikizika kwa in-situ kumakula chifukwa cha kuwonjezeka kwa ductility ndi ductility. Kuphatikiza pa izi, madera a polima osakanikirana amakhalanso ndi zotsatira zolepheretsa ming'alu yaying'ono yophatikizidwa ndi ming'alu. Choncho, ufa wa latex wobalalika ukhoza kuonjezera kupanikizika kosagwira ntchito komanso kusokonezeka kwa zinthu zopangira. Filimu ya polima mumatope a simenti yosinthidwa ndi polima ndi chowopsa chachikulu pamatope owuma a simenti. Kubalalitsidwa kwa ufa wa polima wosabalalika kumachitanso gawo lina lotsogola patsambalo, lomwe ndikuwongolera kumamatira kwa zida zomwe zimalumikizana.
Unyinji wa ufa wa polima wotayika womwe anthu amawona nthawi zambiri pomanga ndi oyera ngati amkaka, ngakhale mithunzi ina ingawonekere. Mapangidwe a redispersible latex ufa amapangidwa makamaka ndi polymer epoxy resin preservative (mkati ndi kunja) kukonza njira ya colloid ndi wothandizira kukana. Pakati pawo, utomoni wapamwamba wa polima epoxy uli pamalo ofunikira a tinthu tating'ono ta mphira ndipo ndiye chigawo chachikulu cha ufa wa polima wotayika.
The dispersible polima ufa safuna madzi apampopi posungira ndi mayendedwe, zomwe zingapulumutse mtengo wamayendedwe a ma module omanga zomangamanga ndikupanga mayendedwe kukhala osavuta komanso othamanga. Ufa wachilengedwe wopangidwanso ndi latex wopangidwa ndi fakitale ya simenti imakhala ndi alumali yayitali ndipo imatha kusungidwa kwa nthawi yayitali osadandaula za kuzizira kocheperako komanso kusungirako kosavuta. Thumba lililonse la ufa wa polima wotayika ndi wocheperako, wopepuka kulemera, komanso wosavuta kugwiritsa ntchito.
