RDP ya Mortar yopanda madzi

Zowonongekansopolima ufa RDP/VAEndi polima emulsion kuti wadutsa olondola kutsitsi kuyanika ndondomeko (komanso kusankha koyenera zina zowonjezera)Powdery polima.Pamene polima youma ufa akumana ndi madzi, amakhala emulsion ndipo akhoza kutaya madzi m'thupi kachiwiri m'kati matope atakhala ndi kuumitsa, kuti polima particles kupanga polima chinthu dongosolo mu matope, amene ali ofanana ndi zochita ndondomeko ya polima emulsion ndi. imagwira ntchito yosintha mumatope a simenti.Emulsion dry modified mortar amatchedwa matope owuma (omwe amadziwikanso kuti dry mix).ed matope, matope osakaniza owuma).

Chifukwa cha ufa youma sayenera kuonedwa ngati polima emulsion kukonzekera, bata vuto, pang'ono kuwonjezera matope akhoza kukwaniritsa chofunika ntchito, ndipo ndi bwino kuposa emulsion n'zosavuta ma CD, yosungirako, mayendedwe ndi kupereka, antifreeze ndi palibe mildew, mabakiteriya, ndi simenti ndi mchenga okonzeka osakaniza zopangidwa limodzi-gawo mankhwala ma CD kuwonjezera ubwino ntchito madzi.Akagwiritsidwa ntchito, mchenga, simenti, ufa wouma wa latex ndi zina zowonjezera zimasakanizidwa ndi kupakidwa pasadakhale, ndipo matope owuma omwe akugwira ntchito bwino amatha kupangidwa nthawi yomweyo powonjezera madzi enaake pomanga munda.Pakatikati pa emulsion youma ufa kukonzekera lagona mu tinthu kukula kwa polima particles ofanana ndi choyambirira emulsion polima particles kapena tinthu kukula kubalalitsidwa.Kuonjezera kuchuluka kwa zoteteza colloid monga polyvinyl mowa mu emulsion, kotero kutipolima ufa RDP/VAEimatha kumwazikananso mu emulsion ikakumana ndi madzi,polima ufa RDP/VAEkhalani ndi dispersability wabwino kuti muwonetsetse kuchita bwino.polima ufa RDP/VAEkupezeka mu kubalalitsidwa kawirikawiri ufa woyera.

Zosakaniza zake ndi:

Utomoni wa polima: womwe uli pakatikati paredispersible polima ufaparticles, ndiyenso chigawo chachikulu cha redispersiblepolima ufa RDP/VAEsewera mbali.

Zowonjezera (mkati) : molumikizana ndi utomoni kusintha utomoni.

Zowonjezera (zakunja): zida zowonjezera zimawonjezedwa kuti ziwonjezere kufalikira kwa zinthu zosinthikapolima ufa RDP/VAE.

Protective colloid: chinthu chosanjikiza cha hydrophilic chokulungidwa pamwamba pa zotayikansopolima ufa RDP/VAEparticles.Ambiri a chitetezo colloid wa redispersiblepolima ufa RDP/VAEndi polyvinyl mowa.

Anti-caking agent: fine mineral filler, yomwe imagwiritsidwa ntchito kwambiri poletsa kuyika kwaredispersible polima ufam'kati mwa kusungirako ndi kuyendetsa ndikuwongolera kuyenda kwaredispersible polima ufa(kutayani m'thumba la mapepala kapena galimoto yamoto).
