Redispersible polymer powder (RDP) ndi polima wa ufa womwe umagwiritsidwa ntchito kwambiri pantchito yomanga kuti apititse patsogolo zida zamatope ndi zida zina za simenti. Ikawonjezeredwa ku zosakaniza zamatope, RDP imathandizira kupanga mgwirizano wamphamvu womwe umawonjezera kuuma kwa zinthu, kulimba komanso kukana kuzizira, kusweka ndi kuwononga mankhwala. Nkhaniyi ifotokoza za zotsatira zabwino za RDP pamatope olimba, kuphatikizapo mphamvu zake zowonjezera mphamvu, kulimbitsa mgwirizano, kupititsa patsogolo ntchito, ndi kuchepetsa kuchepa.
onjezerani mphamvu
Ubwino umodzi waukulu wa RDP pamatope owuma ndikutha kukulitsa mphamvu zazinthu. Izi zimatheka ndi kusintha hydration ndi machiritso a particles simenti, chifukwa wandiweyani ndi wandiweyani zakuthupi. Ma polima mu RDP amakhala ngati chomangira, kudzaza mipata pakati pa tinthu ta simenti ndikupanga mgwirizano wamphamvu. Chotsatira chake ndi matope omwe ali ndi mphamvu zopondereza kwambiri komanso zolimba, zomwe zimapangitsa kuti zisawonongeke kupsinjika, kukhudzidwa ndi kusinthika.
kumamatira kumawonjezera
Chinanso chabwino cha RDP pamatope owuma ndikuthekera kwake kukulitsa mgwirizano. RDP imagwira ntchito ngati cholumikizira pakati pa tinthu tating'ono ta simenti ndi gawo lapansi, ndikuwongolera kumamatira pakati pa zida ziwirizi. Izi ndizofunikira kwambiri pazogwiritsa ntchito monga matailosi, pomwe matope amafunika kumamatira ku gawo lapansi komanso pamwamba pa tile. RDP imatsimikizira mgwirizano wamphamvu komanso wokhalitsa womwe umatha kupirira kupsinjika ndi zovuta zakugwiritsa ntchito tsiku ndi tsiku.
Limbikitsani magwiridwe antchito
RDP imathandizanso kuti matope azigwira ntchito bwino, kuti zikhale zosavuta kusakaniza, kugwiritsa ntchito ndi kumaliza. Ma polima mu RDP amakhala ngati mafuta, amachepetsa kukangana pakati pa tinthu ta simenti kuti aziyenda momasuka. Izi zimapangitsa kuti matope azikhala amadzimadzi komanso osavuta kugwira nawo ntchito, zomwe zimapangitsa kuti zomangamanga ziziyenda bwino komanso kuti zizitha kufalikira. Chotsatira chake ndi chinthu chokhala ndi zinthu zofananira komanso kugwiritsa ntchito mosavuta pamikhalidwe yambiri.
kuchepetsa kuchepa
Imodzi mwazovuta zogwira ntchito ndi matope ndikuti imakonda kuchepa pamene iuma ndikuchira. Shrinkage imatha kuyambitsa ming'alu muzinthuzo, ndikusokoneza kukhazikika kwake komanso kukhazikika kwake. RDP ikhoza kuthandizira kuchepetsa kuchepa poyang'anira kuyanika ndi kuchiritsa kwa zinthuzo. Ma polima mu RDP amapanga filimu yozungulira tinthu tating'ono ta simenti yomwe imakhala ngati chotchinga kutayika kwa chinyezi. Izi zimachepetsa kuyanika ndikupangitsa kuti madzi agawidwe bwino muzinthu zonse, kuchepetsa mwayi wa kuchepa ndi kusweka.
Pomaliza
Zotsatira zabwino za RDP pamatope owuma ndi ambiri komanso ofunika. Mukawonjezeredwa ku zosakaniza zamatope, RDP imawonjezera mphamvu, imawonjezera zomangira, imapangitsa kuti ntchito ikhale yabwino komanso imachepetsa kuchepa. Ubwinowu umapangitsa RDP kukhala chida chamtengo wapatali kwa akatswiri omanga omwe akufuna kumanga nyumba zapamwamba, zolimba komanso zokhalitsa. Pamene ntchito yomanga ikupitabe patsogolo komanso zida zatsopano ndi matekinoloje atsopano akutuluka, RDP ikhalabe gawo lofunikira la omanga ndi makontrakitala padziko lonse lapansi.
