Ufa wokwezeka wa latx umagwiritsidwa ntchito mu js chimphepo chofiyira, bolodi la polystyrene yomanga matope, matope okhazikika, matope osakanikirana, owuma, etc. 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 kusunga madzi, kuwonjezera nthawi yotsegula, ndi kulimbitsa mphamvu.
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 wa simenti, ndi madzi gawo aumbike ndi Ca (OH) 2 mu ndondomeko hydration. Amakhutitsidwa, pomwe ufa wa latex umapanga tinthu tating'onoting'ono ta polima ndi ma depositi pamwamba pa simenti ya simenti / simenti yopanda madzi osakaniza tinthu tating'ono; 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 kusakaniza ndi filler pamwamba kupanga wosanjikiza pafupi-odzaza; 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 kutsekereza khoma ndi utoto siyenera kukhala yamphamvu kuposa pulasitala matope, apo ayi kusweka kudzachitika mosavuta. Mu dongosolo lonse la kutchinjiriza, kusinthasintha kwa putty kuyenera kukhala kokwezeka kuposa kwa zinthu zoyambira. Mwanjira iyi, putty amatha kusinthira bwino kusinthika kwa gawo lapansi ndikubisa mapindikidwe ake omwe amapangidwa ndi zinthu zakunja, kuchepetsa kupsinjika, komanso kuchepetsa kuthekera kwa kusweka ndi kusenda kwa zokutira.
