Redispersible polima ufa amagwiritsa ntchitondi chowonjezera chomwe chimagwiritsidwa ntchito popanga zomatira matailosi.Zimapangidwa ndikuyamba kumwaza kaphatikizidwe ka polima m'madzi ndikuumitsa kuti apange ufa.Therdp polimaufaakhoza kufalikira mosavuta m'madzi kuti apange emulsions okhazikika kapena dispersions.Mu zomatira matailosi, ufa wopangidwanso wa polima umakhala ngati zomangira kapena zomatira zomwe zimathandiza kulimbitsa mgwirizano pakati pa matailosi ndi gawo lapansi.
Zimapangitsanso kusinthasintha, kugwira ntchito komanso kulimba kwa zomatira za matailosi.Mukasakaniza ndi madzi, ufa wopangidwanso wa polima umapanga filimu pamwamba pa matailosi ndi magawo.Firimuyi imapereka mgwirizano wamphamvu ndipo imalepheretsa madzi kuti asalowe pakati pa matayala, kuchepetsa chiopsezo cha kusweka kapena kutsekedwa.Zonsezi, redispersible polima ufa ndi gawo lofunika kwambiri pakupanga zomatira matailosi chifukwa zimathandizira kuti zomatira zikhale zolimba komanso zolimba, ndikuwonetsetsa kuyika kwa matayala kwanthawi yayitali komanso odalirika.
Redispersible latex ufas angagwiritsidwenso ntchito ngati zowonjezera mu konkire formulations kusintha zosiyanasiyana katundu ndi ntchito makhalidwe a konkire.Nazi zina zomwe zimagwiritsidwa ntchito nthawi zambiri za ufa wa polima wopangidwanso mu konkriti:
Kupititsa patsogolo ntchito ndikumatira kwa tile:
Ufa umathandizira kuti konkriti igwire ntchito bwino, kuti ikhale yosavuta kusakaniza, kupopera, ndikuyika.Zimathandizanso kumamatira pakati pa konkriti ndi malo ena, monga zokutira kapena zokutira.
Kupititsa patsogolo Kusinthasintha ndi Kulimbana ndi Crack:
Redispersible polima ufa kumawonjezera kusinthasintha kwa konkriti, ndikupangitsa kuti ikhale yosamva kusweka.Izi ndizofunikira makamaka pakugwiritsa ntchito konkriti komwe kumafunikira mphamvu yolimba kwambiri kapena yosunthika, monga zomangira kapena zokutira zoonda.
Kukhalitsa Kwamphamvu ndi Kukaniza Madzi:
Ufa wa polima umapanga filimu yoteteza kuzungulira tinthu ta simenti mu konkire, ndikupangitsa kuti ikhale yosagwirizana ndi kulowa kwa madzi.Izi zimathandiza kupewa zinthu monga nyengo, kuwonongeka kwa madzi oundana, ndi kuwonongeka komwe kumachitika chifukwa cha kukhudzana ndi chilengedwe.
Kulimbitsa Mphamvu ndi Kulimba:
Redispersible polima ufaimatha kukulitsa mphamvu yopondereza, mphamvu yosunthika komanso kukana konkriti, ndikupangitsa kuti ikhale yolimba komanso yoyenera kugwiritsa ntchito movutikira.
Chepetsani Kutsika ndi Kupititsa patsogolo Kuwongolera kwa Crack:
Zowonjezerazi zimathandizira kuchepetsa kuchepa komanso kuchepetsa chiopsezo cha kusweka panthawi yochiritsa konkire.Izi zimathandiza kupewa ming'alu yosafunikira kuti isapangidwe, zomwe zingasokoneze kukhulupirika kwa konkire.Ponseponse, kuwonjezera kwa ufa wa polima wopangidwanso kuzinthu zopanga konkriti kumatha kupititsa patsogolo magwiridwe antchito, kukhazikika, kukana madzi komanso magwiridwe antchito onse a konkriti, ndikupangitsa kuti ikhale yoyenera pamitundu yambiri yomanga.
