5. Zopangidwa ndi Gypsum:
Mafuta a polima opangidwanso nthawi zambiri amawonjezedwa pamapangidwe opangidwa ndi gypsum kuti awonjezere mphamvu, kumamatira komanso kukana ming'alu.
6. Nembanemba yosalowa madzi:
Kukana kwamadzi kwa RDP kumapangitsa kuti ikhale gawo lofunikira pomanga nembanemba zoletsa madzi.
7. Crack fillers ndi olowa mankhwala:
RDP imathandizira kusinthasintha komanso kumamatira kwa zodzaza ming'alu ndi zophatikizira, kuwonetsetsa kukonzanso koyenera komanso kokhalitsa.
8. Zopangira simenti:
Zopangidwa ndi simenti, monga zokonzera matope ndi ma grouts, zimapindula ndi magwiridwe antchito komanso kulimba koperekedwa ndi RDP.
9. Kupaka utoto:
Kukhalitsa komanso kusasunthika kwa nyengo kwa utoto wakunja kumawonjezeka RDP ikaphatikizidwa m'mapangidwe ake.
10. Miphika ndi Zisindikizo:
Kusinthasintha ndi zomatira za RDP kumapangitsa kuti ikhale chowonjezera pakupanga ma caulking ndi sealant, kuwongolera magwiridwe antchito pakapita nthawi.
Malingaliro a Zachilengedwe ndi Malamulo
1. Kukhudza chilengedwe:
Redispersible polima ufa nthawi zambiri amaonedwa kuti ndi ochezeka ndi chilengedwe chifukwa amathandizira kukulitsa moyo ndi kulimba kwa zinthu, kuchepetsa kufunika kosintha pafupipafupi.
2. Kutsata Malamulo:
Opanga ndi ogwiritsa ntchito RDP akuyenera kutsatira malamulo amdziko ndi akunja okhudzana ndi kagwiritsidwe ntchito ka ma polima muzomangamanga.
Pomaliza
Redispersible polima ufa ndi zofunika multifunctional zowonjezera mu ntchito yomanga.Imawonjezera mphamvu ya zinthu zosiyanasiyana, kuphatikizapo kumamatira, kusinthasintha ndi kukana madzi, zomwe zimapangitsa kuti zikhale zofunikira kwambiri pakupanga zomatira, matope, zokutira ndi zina.Ntchito zosiyanasiyana za RDP zimathandizira kumanga zolimba, zolimba komanso zogwira ntchito kwambiri.Pamene ukadaulo ukupitilirabe patsogolo, ntchito ya ufa wa polima wotayikanso ikuyenera kukulirakulira, zomwe zikukhudzanso kugwiritsa ntchito zida ndi njira zomangira zomwe zikusintha.
