Muzomangamanga zamakono, matope, monga maziko opangira zomangamanga, amagwiritsidwa ntchito kwambiri pomanga, pulasitala, kusanja pansi, kutsekereza madzi ndi anti-seepage ndi zina. Pofuna kupititsa patsogolo ntchito yonse ya matope, makamaka mphamvu zomangira, kusinthasintha ndi ntchito yomanga, zowonjezera zosiyanasiyana zatuluka. Mwa iwo,redispersible polima ufa (RDP)monga zomatira matope okwera kwambiri zimagwira ntchito yofunika kwambiri pantchito yomanga.
1. Kodi RDP ndi chiyani?
RDP ndi ufa wopangidwa ndi ma emulsion apamwamba a ma polima a polymer ndi njira yowumitsa yopopera, yokhala ndi redispersibility yabwino. Pamene RDP abwera kukhudzana ndi madzi, akhoza anabalalitsidwa mu khola emulsion, potero kubwezeretsa ake oyambirira emulsion katundu. Izi nthawi zambiri zimakhala ndi ethylene-vinyl acetate copolymer (EVA), ethylene-vinyl acetate-acrylic acid copolymer (VEOVA), ma polima a acrylic ester, ndi zina zotero, ndi ma colloids oteteza (monga polyvinyl mowa) ndi zina zowonjezera ntchito zimawonjezedwa malinga ndi zofunikira za ntchito.
2. Kachitidwe ka RDP mumatope
RDP imagwira ntchito zotsatirazi mumatope osakaniza:
Limbikitsani kumamatira: RDP ikabalalitsidwanso m'madzi, tinthu tating'onoting'ono ta polima timatha kulowa ndikukulunga pakati pa matope ndi gawo lapansi ndikupanga filimu yolimba ya polima, yomwe imathandizira kwambiri kulumikizana kwa matope.
Sinthani kusinthasintha: Gawo la polima limatha kusintha kusinthasintha kwa matope ndikuchepetsa chiwopsezo cha kusweka komwe kumachitika chifukwa chakukula kwamafuta ndi kutsika kapena mphamvu zakunja. Ndizoyenera makamaka kumadera omwe ali ndi mapindikidwe akuluakulu a maziko.
Kupititsa patsogolo ntchito yomanga: RDP imatha kukonza magwiridwe antchito komanso kusungunuka kwamadzi amatope, kupangitsa kuti ikhale yofewa komanso yosavuta kugwiritsa ntchito, ndikuwongolera ntchito yomanga.
Limbikitsani kukana kwa madzi ndi kukana kwa nyengo: RDP imatha kupititsa patsogolo kukana kwamadzi mumtondo, kuteteza kulowetsedwa kwa chinyezi, ndikuwonjezera kukana kwake kumayendedwe oundana ndi kulimba.
Limbikitsani luso lowongolera: Filimu ya polima yomwe imapangidwa panthawi yowumitsa imakhala ndi kusungunuka kwina, komwe kumathandiza kukana ming'alu ya shrinkage yomwe imayambitsidwa ndi kutuluka kwa madzi.
3. Minda yogwiritsira ntchito RDP
Monga zinthu zambiri zosinthidwa, RDP imagwiritsidwa ntchito kwambiri m'magawo omanga awa:
Zomatira matailosi ndi guluu wa matailosi: Powonjezera mphamvu zomangirira ndi kusinthasintha, ndizoyenera kuyika matailosi pakhoma ndi pansi, miyala yayikulu, ndi zina zambiri, makamaka matailosi otsika omwe amayamwa madzi.
Dongosolo lotsekereza lakunja (EIFS): Kugwiritsa ntchito RDP pomanga matope ndi matope odana ndi kukwapula kumathandiza kukulitsa kukhulupirika, kukana ming'alu ndi magwiridwe antchito a dongosolo.
Mtondo wodziyimira pawokha: Sinthani magwiridwe antchito amadzimadzi komanso omangika, onjezerani mphamvu yodziyimira pawokha, ndikupewa kusweka ndi kung'ambika.
Tondo lopanda madzi ndi matope okonzera: Limbikitsani kachulukidwe ndi kukana madzi, ndikuwongolera kudalirika kwamagawo omwe akonzedwa.
Dongo la pulasitala ndi wosanjikiza: Kupititsa patsogolo ntchito yomanga ndikukana kusweka kwa shrinkage ndikuwonjezera moyo wautumiki.
4. Njira zopewera kugwiritsa ntchito
Ngakhale RDP ili ndi magwiridwe antchito osiyanasiyana, mfundo zotsatirazi ziyenera kuzindikirikabe pakufunsira kwenikweni:
Kugwirizana ndi makina a simenti: Mtundu woyenera kufananiza ndi zinthu za simenti monga simenti ndi laimu ziyenera kusankhidwa kuti zitsimikizire kuti kusanja, kulekanitsa madzi kapena zovuta sizingachitike.
Kuwongolera zachilengedwe: Pomanga, chidwi chiyenera kuperekedwa ku kutentha ndi chinyezi, ndipo kumanga pamalo owuma kwambiri kapena onyowa kuyenera kupewedwa kuti zisokoneze mapangidwe a filimu ya polima.
Kusungirako: RDP iyenera kusungidwa pamalo owuma komanso ozizira kuti pasakhale chinyezi komanso kusanjikana; iyenera kugwedezeka kwathunthu musanagwiritse ntchito.
Kuwongolera Mlingo: Ngakhale kugwiritsa ntchito kwambiri RDP kumatha kupititsa patsogolo magwiridwe antchito, kumawonjezeranso ndalama komanso kungakhudze magwiridwe antchito amatope. Iyenera kuwonjezeredwa moyenerera malinga ndi zosowa zenizeni za polojekitiyi.
Ndi kutchuka kwa lingaliro la zomangira zobiriwira ndi kuwongolera kwa digiri ya mafakitale omanga, chitukuko chaRDPikupitanso kuchitetezo cha chilengedwe, kutsika kwa VOC (zosakanikirana ndi zinthu zachilengedwe), komanso kuchita bwino kwambiri. Nthawi yomweyo, kafukufuku ndi chitukuko cha RDP yogwira ntchito ikukula kwambiri. Mafuta osinthika a polima osinthika monga kudziyeretsa, antibacterial ndi anti-mildew, ndi zoziziritsa moto zikulowa pang'onopang'ono pamsika, ndikukulitsa chiyembekezo chake pazomangira zogwira ntchito kwambiri.
