Dispersible polima ufa (RDP) ndi mankhwala apamwamba a polima omwe amagwiritsidwa ntchito pomanga ndi mafakitale. Ndi zinthu ufa akamagwira kutsitsi kuyanika ndi emulsion polima, ndipo ali ndi katundu redispersing m'madzi kupanga khola emulsion. RDP imagwiritsidwa ntchito kwambiri muzomangira zosiyanasiyana, makamaka mumatope owuma, zomatira matailosi, makina otsekereza khoma (ETICS), ndi zokutira zosalowa madzi.
1. Dothi louma
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi RDP ndi mumatope owuma. Itha kukulitsa kumamatira, kusinthasintha komanso kukana kwa matope, kupangitsa kuti ikhale yosavuta kumanga ndikuwongolera mtundu wa zomangamanga. Makamaka, ntchito ya RDP mumatope owuma imaphatikizapo:
Limbikitsani mphamvu zomangira: RDP imatha kupanga filimu yotanuka matope atachiritsidwa. Kanemayu ali ndi mphamvu yolumikizirana kwambiri, yomwe imatha kuwongolera bwino kumamatira pakati pa matope ndi gawo lapansi ndikuchepetsa chiopsezo cha kusweka ndi kugwa.
Limbikitsani kusinthasintha: Popeza filimu yopangidwa ndi RDP imasinthasintha, imatha kusunga umphumphu wa matope ndikuletsa kusweka pamene nyumba yomangayo imayenda kapena kupunduka pang'ono.
Kupititsa patsogolo ntchito yomanga: RDP imatha kuwongolera kuchuluka kwamafuta ndi mafuta amatope, kupangitsa kuti ntchito yomanga ikhale yosavuta, makamaka kuchepetsa kulimbikira kwa ogwira ntchito komanso kupititsa patsogolo ntchito yomanga pomanga pamalo akulu.
2. Zomatira matailosi
Pomatira matayala, kuwonjezera kwa RDP kumatha kupititsa patsogolo ntchito zomatira matailosi, kuphatikiza mphamvu zomangirira, anti-slip properties ndikumanga mosavuta.
Limbikitsani kumamatira: RDP ikhoza kupanga chomangira cholimba pambuyo pouma matailosi, kuonetsetsa kuti matailosi amatha kumangirizidwa mwamphamvu pakhoma kapena pansi.
Limbikitsani zinthu zotsutsana ndi kutsetsereka: RDP imatha kuletsa matailosi kuti asaterere pomanga ndikuwonetsetsa kuti matailosi azikhala momwe adakonzedweratu panthawi yopaka.
Limbikitsani ntchito yomanga: Pambuyo powonjezera RDP ku zomatira za matailosi, kusinthasintha kwake kumakhala kosavuta kuwongolera, zomatira ndizofanana panthawi yopangira, ndipo zovuta pakumanga zimachepetsedwa.
3. Dongosolo lotsekera khoma lakunja (ETICS)
Kugwiritsiridwa ntchito kwa RDP pamakina otchinjiriza kunja kumawonekera makamaka pakukulitsa mphamvu zomangira komanso kulimba kwa gawo lotsekera. Chigawo chotchinjiriza nthawi zambiri chimagwiritsa ntchito zinthu zopepuka monga polystyrene (EPS) kapena polystyrene extruded (XPS), zomwe zimafunikira kumangirizidwa mwamphamvu ku khoma lakunja la nyumbayo, ndipo kuwonjezera kwa RDP kumatha kupititsa patsogolo magwiridwe antchito azinthu izi.
Mphamvu yomangirira yowonjezereka: RDP imapangitsa kuti bolodi lotsekera likhale lolimba kwambiri pakhoma lakunja, kuletsa wosanjikiza kuti asagwe chifukwa cha kusintha kwa kutentha kapena mphamvu zakunja.
Kukhazikika kokhazikika: RDP imathanso kupititsa patsogolo magwiridwe antchito oletsa kukalamba ndikuwonjezera moyo wautumiki wa nyumbayo, makamaka m'malo ovuta.
4. Zotchingira zopanda madzi
Kugwiritsa ntchito kwa RDP mu zokutira zopanda madzi makamaka kumapangitsa kuti asalowe madzi, kusinthasintha komanso kukana kwa ming'alu. Filimu ya polima yopangidwa ndi RDP mu zokutira imatha kuteteza kulowa kwa madzi, potero kumapangitsa kuti madzi asalowe.
Kuchita bwino kopanda madzi: Kapangidwe kakanema kamene kamapangidwa ndi RDP kumatha kulepheretsa kulowa kwamadzi, makamaka m'malo omwe ali ndi zofunikira zosalowa madzi monga madenga, zipinda zapansi ndi zimbudzi.
Kuchulukitsa kusinthasintha: RDP mu zokutira zopanda madzi zimatha kupatsa zokutira kusinthasintha kwina, kusinthira pang'ono gawo lapansi, ndikuletsa zokutira kuti zisagwe.
Limbikitsani ntchito yomanga zokutira: Kuphatikizika kwa RDP kumapangitsa kupanga zokutira zopanda madzi kukhala zosavuta, zokutira zimakhala zofananira komanso zocheperako ku thovu ndi ming'alu.
5. Ntchito zina
Kuphatikiza pazigawo zazikuluzikulu zomwe zili pamwambapa, RDP itha kugwiritsidwanso ntchito pazipinda zodziyimira pawokha, zida zokonzetsera khoma, zinthu za gypsum ndi matope otsekereza matenthedwe. M'magwiritsidwe awa, RDP imathandizanso kukulitsa kaphatikizidwe kazinthu, kukonza zomangamanga, ndikuwonjezera kukana ndi kulimba.
Monga mankhwala opangira bwino kwambiri, ufa wobalalika wa latex (RDP) umagwiritsidwa ntchito kwambiri m'madera ambiri chifukwa cha mankhwala ake apadera. Sikuti zimangowonjezera magwiridwe antchito a zida zomangira, komanso zimathandizira kuti ntchito yomanga ikhale yosavuta komanso yolimba ya nyumba yomaliza. Ndi chitukuko chosalekeza chaukadaulo wa zomangamanga, gawo logwiritsira ntchito RDP lipitilira kukula, ndipo likuyembekezeka kuchitapo kanthu pazantchito zambiri zamafakitale ndi zomangamanga m'tsogolomu.
