Ufa wa polima wosungunukanso (RDP)ndi chinthu chofunika kwambiri cha polima chachilengedwe, chomwe chimagwiritsidwa ntchito kwambiri m'magawo ambiri monga zomangamanga, zipangizo zomangira, zokongoletsera ndi mafakitale. Ndi ufa woyenda momasuka womwe umapezeka ndi ma emulsion ouma (monga ma vinyl acetate-ethylene copolymers, ma vinyl acetate-acrylate copolymers, ndi zina zotero). Ufa uwu ukhoza kufalikiranso kuti upange emulsion yokhazikika mutasakaniza ndi madzi, potero kusunga magwiridwe antchito a emulsion yoyambirira.
1. Makhalidwe oyambira
Ufa wa polima wosungunukanso uli ndi makhalidwe ofunikira awa:
Kuthanso kusungunuka bwino: Itha kusungunuka mwachangu kukhala emulsion yoyambirira m'madzi, zomwe zimapangitsa kuti ikhale yogwira ntchito bwino.
Kuchita bwino kwambiri kwa mgwirizano: Kulimbitsa mphamvu ya mgwirizano pakati pa zinthuzo ndi substrate.
Konzani kusinthasintha: Konzani kukana ming'alu ya zinthuzo ndipo ndizoyenera kugwiritsa ntchito zina zomwe zimafuna kusinthasintha kwakukulu.
Kukana madzi ndi kukana alkali: Kumakhalabe kokhazikika m'malo okhala ndi alkali monga simenti kapena laimu.
Choletsa ukalamba komanso kukana nyengo: Chimasungabe magwiridwe antchito okhazikika pansi pa kuwala kwa ultraviolet kapena nyengo yovuta.
2. Ntchito zazikulu
Guluu wa matailosi ndi guluu wothandiza matailosi Ufa wa polima wosinthika umagwiritsidwa ntchito kwambiri mu guluu wa matailosi. Umathandizira kusinthasintha ndi mphamvu yolumikizira zinthu zomatira matailosi, zomwe zimathandiza kuti matailosi azilumikizidwa mwamphamvu pa zinthu zosiyanasiyana, makamaka zoyenera matailosi akuluakulu, omwe salowa madzi ambiri.
Ufa wa putty ndi putty yakunja ya khoma Kuwonjezera ufa wa polima wosinthika ku ufa wa putty wamkati ndi kunja kwa khoma kungathandize kwambiri kumamatira, kukana madzi ndi magwiridwe antchito a putty pomanga. Makamaka pakugwiritsa ntchito khoma lakunja, kukana kwa nyengo kumakhala ndi gawo lofunikira popewa kutayika ndi kusweka kwa ufa.
Zipangizo zodziyimira pansi Pansi pa simenti yodziyimira payokha imafuna kusinthasintha bwino komanso kumamatira bwino. Ufa wa polima wosungunukanso ungathandize kuti umangidwe mosavuta komanso kuti ukhale wosavuta kupanga filimu, komanso kuchepetsa ming'alu ndi kusweka kwa nthaka.
Dongosolo la matope oteteza kutentha (monga dongosolo la EIFS lakunja la khoma loteteza kutentha) Kuwonjezera ufa wa polima wobwezeretsedwanso ku matope oteteza kutentha kungathandize kuti matope ndi zinthu zina zigwirizane bwino (monga bolodi la thovu, bolodi la polystyrene, ndi zina zotero), kulimbitsa kukana ming'alu, kukana chisanu komanso kukulitsa moyo wa dongosololi.
Chomangira chosalowa madzi Kugwiritsa ntchito RDP mu fomula ya chomangira chosalowa madzi kungathandize kwambiri kusinthasintha ndi kusalowa madzi kwa chinthucho, kuti chizitha kugwira ntchito bwino pamalo ozizira komanso ogwirizana ndi madzi kwa nthawi yayitali.
Kukonza matope ndi cholumikizira Ufa wa polima wosinthika ungathandize kuti matope okonzanso azigwirana bwino komanso kuti asagwe m'malo okonzedwa. Kuwonjezera RDP ku cholumikizira kungathandize kuti zinthu zigwirizane bwino.
Zipangizo zopangidwa ndi gypsum Kugwiritsa ntchito ufa wa polymer wosinthika mu zigawo zoyezera zopangidwa ndi gypsum ndi zomangira za gypsum kumatha kulimbitsa mphamvu zawo zomangira, kukana ming'alu komanso magwiridwe antchito omanga, ndipo ndi gawo lofunikira kwambiri pa zipangizo zomangira zobiriwira.
3. Ubwino wa ntchito
Kapangidwe kosavuta Ufa wa polima wosungunuka nthawi zambiri umakhala mu mawonekedwe a ufa wouma ndipo ukhoza kusakanizidwa mwachindunji ndi zinthu zina zouma (monga simenti, mchenga, ndi zina zotero) popanda mankhwala ena owonjezera. Ungagwiritsidwe ntchito pamalopo powonjezera madzi, omwe ndi osavuta kunyamula ndi kumanga.
Kuwongolera magwiridwe antchito athunthu Sikuti imangowonjezera magwiridwe antchito a matope, komanso imawongolera mawonekedwe ake monga kukana ming'alu, kukana chisanu, kukana kuwonongeka komanso kusinthasintha. Ndi chinthu chofunikira kwambiri pakukweza ubwino wa zipangizo zomangira.
Chitetezo ndi chitetezo cha chilengedwe Ufa wa polima wosungunukanso ndi wopanda poizoni komanso woopsa, umakwaniritsa zofunikira za nyumba zamakono zotetezera chilengedwe komanso mpweya wochepa wa VOC, ndipo umagwiritsidwa ntchito kwambiri m'nyumba zobiriwira.
4. Zochitika zamtsogolo pa chitukuko
Chifukwa cha kufunikira kwakukulu kwa zipangizo zomangira zobiriwira komanso zosawononga chilengedwe komanso luso lopanga zinthu zatsopano, njira ndi magwiridwe antchito a ufa wa Redispersible polymer zikukonzedwanso, zomwe zikupita patsogolo kwambiri, kukana nyengo, komanso kutulutsa mpweya wochepa wa VOC. Nthawi yomweyo, kuphatikiza ndi minda yatsopano yazinthu monga nanotechnology ndi zinthu zopangidwa ndi bio, kugwiritsa ntchito kosatha komanso kogwira ntchito kwa RDP kudzakhalanso cholinga cha kafukufuku ndi chitukuko chamtsogolo.
Monga chowonjezera cha polima chogwira ntchito,RDPImagwira ntchito yofunika kwambiri m'nyumba zamakono ndi zipangizo zomangira mafakitale chifukwa cha magwiridwe ake abwino komanso ntchito zake zosiyanasiyana. Kuyambira pakupanga matailosi mpaka kulinganiza makoma, kuyambira pakupanga pansi mpaka kukonza madzi osalowa madzi, cholinga chake ndi kupititsa patsogolo magwiridwe antchito a zipangizo ndi ntchito yomanga, ndikulimbikitsa makampani onse a zipangizo zomangira kuti apite patsogolo kwambiri komanso kuti azitsatira malangizo abwino kwambiri.
