Redispersible polymer powder (RDP) ndizofunikira kwambiri pazomangira zamakono, makamaka zomatira, matope, ndi pulasitala.Pokulitsa mawonekedwe akuthupi ndi makemikolo azinthuzi, ma RDPs amagwira ntchito yofunikira kwambiri pakuwongolera kulimba ndi magwiridwe antchito a zomangamanga.
Kupanga ndi Njira ya RDP
RDP imapangidwa ndi kupopera-kuyanika emulsion ya zinthu za polymeric, zomwe zimatengera vinyl acetate-ethylene (VAE), acrylic, kapena styrene-butadiene.Njirayi imasintha emulsion kukhala ufa wabwino womwe ukhoza kutulutsidwanso m'madzi, ndikukonzanso kubalalika koyambirira kwa polima.Mukawonjezeredwa ku zosakaniza zamatope owuma, RDP imayambiranso ikakumana ndi madzi, ndikupanga filimu yofanana ndi yokhazikika mkati mwa matrix omatira.
Kulimbikitsa Kulimbana ndi Madzi
Kupanga Mafilimu: Pakutha madzi, tinthu tating'onoting'ono ta RDP timalumikizana kuti tipange filimu yopitilira polima pamatrix onse omatira.Firimuyi imakhala ngati chotchinga, kuchepetsa kwambiri porosity ndi madzi permeability wa zomatira.Kanemayo amatchinga ngalande za capillary, kuletsa kulowa kwa madzi ndikuwonjezera mphamvu zomatira zoletsa madzi.
Katundu Wa Hydrophobic: Mitundu yambiri ya RDP imaphatikizapo ma hydrophobic agents kapena zosintha zomwe zimapangitsa kuti madzi asasunthike.Zigawo za hydrophobic izi zimachepetsa kuyamwa kwamadzi kwa zomatira, kuwonetsetsa kuti zimagwira ntchito kwanthawi yayitali ngakhale mumikhalidwe yonyowa.
Kugwirizana Kwambiri ndi Kusinthasintha: RDP imapangitsa mgwirizano wamkati wa zomatira, kupititsa patsogolo mphamvu zake zomangira ndi kusinthasintha.Kusinthasintha kumeneku n'kofunika kwambiri poletsa kupanga ming'alu ndi mipata yomwe ingalole kuti madzi alowe.Zomatira zomwe zimatha kukulitsa kufalikira kwamafuta ndi kutsika popanda kusweka zimasunga kukhulupirika kwake komanso kukana madzi pakapita nthawi.
Kulimbikitsa Kulimbana ndi Nyengo
Kukhazikika kwa UV: Mapangidwe a RDP nthawi zambiri amapangidwa kuti asawonongeke ndi kuwala kwa ultraviolet (UV).Kanema wa polima wopangidwa ndi RDP ndi wokhazikika wa UV, kuteteza zomatira zapansi ku zotsatira zoyipa zakukhala padzuwa kwanthawi yayitali.Kukhazikika kumeneku kumatsimikizira kuti zomatirazo zimakhalabe ndi mphamvu ndi kusungunuka ngakhale pambuyo pa nthawi yaitali ndi dzuwa.
Kukaniza kwa Thermal: Zida zomangira zimatha kusiyanasiyana kutentha kwambiri, komwe kungayambitse kukula ndi kutsika.Zomatira zosinthidwa za RDP zimawonetsa kukana kwamafuta, kusunga mphamvu zawo zomangira komanso kusinthasintha pamitundu yosiyanasiyana ya kutentha.Katunduyu amalepheretsa zomatira kuti zisawonongeke nyengo yozizira kapena zofewa kwambiri pakatentha, potero zimakulitsa kulimba kwake kwanyengo.
Kukaniza Kuzizira kwa Kuzizira: M'madera ozizira, zipangizo zimadutsa mobwerezabwereza kuzizira, zomwe zingakhale zowononga kwambiri.Kusinthasintha ndi kulumikizana komwe kumaperekedwa ndi RDP kumathandizira zomatira kupirira izi popanda kutaya kukhulupirika.Filimu ya polima imagwira ntchito ngati choyambitsa mantha, kuchepetsa kupsinjika komwe kumachitika chifukwa cha kuzizira komanso kusungunuka.
Mapulogalamu Othandiza
Exterior Insulation and Finish Systems (EIFS): RDP imagwiritsidwa ntchito kwambiri mu EIFS, komwe madzi ndi nyengo ndizofunika kwambiri.Ufa wa polima umatsimikizira kuti zomatira m'makinawa zimatha kukana kulowetsedwa kwa chinyezi komanso kupirira nyengo zosiyanasiyana, kuteteza kukhulupirika kwadongosolo komanso kutsekemera kwadongosolo.
Zomatira za matailosi ndi ma Grouts: Pazinthu zonse zamkati ndi kunja, zomatira matailosi ndi ma grouts osinthidwa ndi RDP amawonetsa magwiridwe antchito apamwamba.Amakana kulowa m'madzi ndikuletsa matailosi kuti asatayike kapena kuwonongeka chifukwa cha nyengo.Izi ndizofunikira makamaka m'malo akunja komwe matailosi amakumana ndi mvula, chisanu, ndi dzuwa.
Konzani Mitondo ndi Patching Compounds: Pakukonza konkire ndi kuzigamba, RDP imakulitsa kulimba kwa zida zokonzera.Zimatsimikizira kuti zipangizozi zimagwirizana bwino ndi konkire yomwe ilipo, kupereka njira yothetsera madzi ndi nyengo yomwe imatalikitsa moyo wa kukonzanso.
Zopindulitsa Zachilengedwe ndi Zachuma
Kutalika kwa Moyo Wotalikirapo: Pokonza zolimba za madzi ndi nyengo, RDP imakulitsa moyo wa zomatira zomangira ndi zomangira zomwe zimagwiritsidwa ntchito. Izi zimachepetsa kufunika kokonzanso pafupipafupi ndikusintha, zomwe zimapangitsa kutsika mtengo wokonza ndi kugwiritsa ntchito zinthu.
Mphamvu Zamagetsi: Pazinthu ngati EIFS, zomatira zowonjezeredwa ndi RDP zimathandizira kuti pakhale ntchito yabwino yotchinjiriza posunga kukhulupirika kwa makina otchinjiriza.Izi zitha kubweretsa kupulumutsa kwakukulu kwamagetsi pakutenthetsa ndi kuziziritsa nyumba, kulimbikitsa kukhazikika.
Zinyalala Zochepekera: Kugwiritsa ntchito zomatira zolimba, zolimbana ndi nyengo kumachepetsa zinyalala zapanyumba zopangidwa ndi zinthu zomwe zalephera kapena kuwonongeka.Izi zimathandiza kuti ntchito yomanga ikhale yokhazikika komanso kuchepetsa kuwonongeka kwa chilengedwe pa ntchito yomanga.
Redispersible polima ufa ndi chowonjezera chosinthira pazomatira zomangira, zomwe zimapatsa madzi ovuta komanso kukana kwanyengo.Kutha kwake kupanga filimu yoteteza polima, yophatikizidwa ndi mawonekedwe a hydrophobic komanso kusinthasintha kowonjezereka, kumapangitsa zomatira zosinthidwa za RDP kukhala zolimba polimbana ndi zovuta za chinyezi ndi nyengo.Pophatikizira RDP muzomangamanga, omanga ndi mainjiniya amatha kuonetsetsa kuti nyumba zokhala ndi nthawi yayitali, zolimba zomwe zili ndi zida zotha kupirira zovuta zachilengedwe.Izi sizimangowonjezera ntchito ndi kudalirika kwa ntchito zomanga komanso zimalimbikitsa kukhazikika komanso kutsika mtengo kwamakampani.
