Redispersible latex ufa amagwiritsidwa ntchito mu chigawo chimodzi cha JS chotchingira madzi, polystyrene board bonding matope pomanga nyumba, matope oteteza pamwamba, polystyrene tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono kuwonekera. gawo la zosintha ma inorganic gelling zakhala zikugwiritsidwa ntchito kwambiri.
Kuonjezera redispersible latex ufa ku putty ufa kumatha kuwonjezera mphamvu zake, kukhala ndi zomatira zolimba komanso zamakina, ndikuthandizira kukonza kuuma. Ili ndi kukana kwamadzi bwino, permeability, komanso kulimba kwambiri. Zamchere, sizimva kuvala, ndipo zimatha kupititsa patsogolo kusungidwa kwa madzi, kuwonjezera nthawi yotsegula, ndi kukulitsa kulimba.
Pamene redispersible latex ufa akawitsidwa wogawana mu putty ufa ndi kusakaniza ndi madzi, ndi omwazikana mu zabwino polima particles; gel osakaniza simenti pang'onopang'ono aumbike mwa hydration koyamba simenti, ndi madzi gawo aumbike Ca (OH) 2 mu ndondomeko hydration. Amakhutitsidwa, pamene ufa wa latex umapanga tinthu tating'onoting'ono ta polima ndi ma depositi pamwamba pa simenti ya simenti / simenti yopanda madzi osakaniza; monga simenti imawonjezereka, madzi a m'kati mwa capillaries amachepetsa, ndipo tinthu tating'onoting'ono timachepa pang'onopang'ono mu capillaries. Zomatira / unhydrated simenti tinthu osakaniza ndi filler pamwamba kupanga wosanjikiza odzaza kwambiri; pansi pa zochita za hydration anachita, m'munsi mayamwidwe wosanjikiza ndi pamwamba evaporation, madzi ndi yafupika, ndipo anapanga zakhala zikuzunza m'miyoyo wosanjikiza amasonkhana mu filimu, amene amamanga hydration anachita mankhwala Pamodzi iwo kupanga wathunthu maukonde dongosolo. Dongosolo lophatikizika lomwe limapangidwa ndi simenti ya hydration ndi mapangidwe a filimu ya latex powder amatha kupititsa patsogolo kukana kwamphamvu kwa putty kudzera munjira yolumikizirana.
Putty yomwe imagwiritsidwa ntchito ngati chosanjikiza pakati pa khoma lakunja ndi utoto siyenera kukhala yamphamvu kuposa pulasitala matope, apo ayi kung'ambika kumachitika mosavuta. Mu dongosolo lonse la kutchinjiriza, kusinthasintha kwa putty kuyenera kukhala kokwezeka kuposa kwa zinthu zoyambira. Mwanjira imeneyi, putty amatha kusinthira bwino kusinthika kwa gawo lapansi ndikusunga mapindikidwe ake omwe amachokera kunja kwa chilengedwe, kuchepetsa kupsinjika, komanso kuchepetsa kuthekera kwa kusweka ndi kupukuta kwa zokutira.
