Kuwonjezera ma polima kumatha kupititsa patsogolo kusasunthika, kulimba, kukana ming'alu komanso kukana kwamatope ndi konkriti. Permeability ndi mbali zina zimakhala ndi zotsatira zabwino. Poyerekeza ndi kupititsa patsogolo mphamvu ya flexural ndi mphamvu yomangirira ya matope ndi kuchepetsa kuphulika kwake, zotsatira za redispersible latex ufa pa kupititsa patsogolo kusungirako madzi kwa matope ndi kupititsa patsogolo mgwirizano wake ndizochepa.
Redispersible polima ufa nthawi zambiri kukonzedwa ndi kupopera kuyanika pogwiritsa ntchito emulsion alipo. Njira ndi kupeza polima emulsion kudzera emulsion polymerization, ndiyeno kupeza kudzera kutsitsi kuyanika. Pofuna kupewa kuphatikizika kwa ufa wa latex ndikuwongolera magwiridwe antchito asanayambe kuyanika kutsitsi, zowonjezera zina zimawonjezeredwa, monga ma bactericides, zowonjezera zowumitsa zopopera, mapulasitiki, ma defoamers, ndi zina zambiri, pakuyanika kutsitsi, kapena mutangomaliza kuyanika. Wothandizira kumasulidwa amawonjezedwa kuti ateteze kusungunuka kwa ufa panthawi yosungira.
Ndi kuchuluka kwa zili redispersible latex ufa, dongosolo lonse akufotokozera pulasitiki. Pankhani ya mkulu latex ufa okhutira, ndi polima gawo mu matope anachiritsa pang`onopang`ono kuposa inorganic hydration mankhwala, matope akukumana kusintha Mkhalidwe ndi kukhala zotanuka thupi, ndi hydration mankhwala a simenti amakhala "filler". . Kanema wopangidwa ndi redispersible latex ufa wogawika pamawonekedwewo ali ndi gawo linanso lofunikira, ndiko kuti, kupititsa patsogolo kumamatira kuzinthu zomwe zalumikizidwa, zomwe ndizoyenera kumalo ena ovuta kumamatira, monga mayamwidwe otsika kwambiri kapena Osakhala nawo. malo oyamwa (monga konkire yosalala ndi zinthu za simenti, mbale zachitsulo, njerwa zofananira, malo a njerwa, ndi zina zotero) ndi zinthu zakuthupi. (monga matabwa a EPS, mapulasitiki, ndi zina zotero) ndizofunikira kwambiri. Chifukwa kugwirizana kwa zomatira muzinthu zakuthupi kumatheka kudzera mu mfundo yoyika makina, ndiko kuti, hydraulic slurry imalowa m'mipata ya zinthu zina, imalimba pang'onopang'ono, ndipo pamapeto pake imamangiriza matope ngati fungulo lotsekeredwa mu loko. Pamwamba pa zinthu, kwa pamwamba zovuta-chomangira pamwamba, sangathe mogwira kudutsa mkati mwa zinthu kupanga wabwino makina embedding, kotero kuti matope ndi zomatira yekha inorganic si mogwira anamangidwa kwa izo, ndi kugwirizana. limagwirira wa polima ndi osiyana. , Polima imamangirizidwa pamwamba pa zipangizo zina ndi mphamvu ya intermolecular, ndipo sizidalira porosity ya pamwamba (zowonadi, pamwamba pake ndi kukhudzana kowonjezereka kumapangitsa kuti adhesion).
