RDP yeMota isina mvura

Redispersiblepolymer poda RDP/VAEis emulsion yepolymer yakaitwa nenzira kwayo yekuomeswa kwekupfapfaidza (pamwe nekusarudzwa kwezvinowedzera zvakakodzera)Powdery polymer.Kana iyo polima yakaoma poda ikasangana nemvura, inova emulsion uye inogona kupera mvura zvakare mukugadzika kwedhaka uye kuomesa, kuitira kuti zvimedu zvepolymer zvigadzire chimiro chepolymer mudhaka, inofanana nekuita kwepolymer emulsion uye. inoita basa rekugadzirisa mudhaka resimende.Emulsion yakaoma modified mortar inonzi yakaoma dhaka (inozivikanwawo semusanganiswa wakaomaed dhaka, dhaka rakaoma rokusanganisa).

Nemhaka yehupfu hwakaoma haifaniri kuonekwa sepolymer emulsion kugadzirira, dambudziko rekugadzikana, zvishoma zvekuwedzera dhaka zvinogona kuita zvinodiwa, uye zviri nani kudarika emulsion iri nyore kurongedza, kuchengetedza, kutakura uye kupa, antifreeze uye. hapana chakuvhe, mabhakitiriya, uye nesamende nejecha yakagadzirira-yakavhenganiswa yakagadzirwa nechinhu chimwe-chikamu zvigadzirwa kurongedza wedzera mvura yekushandisa zvakanakira.Kana yaiswa, jecha, simende, latex poda yakaoma uye zvimwe zvinowedzera zvinosanganiswa uye zvakarongedzwa zvakanaka nguva isati yasvika, uye dhaka rakaoma rine kushanda zviri nani rinogona kuitwa pakarepo nekuwedzera imwe mvura mukuvaka kwemunda.Iyo yakakosha emulsion yakaoma poda kugadzirira iri muchikamu chehukuru hwepolymer zvimedu zvakafanana nepakutanga emulsion polymer particles kana particle size dispersion.Kuwedzera imwe chiyero chekudzivirira colloid yakadai se polyvinyl doro mu emulsion, kuitira kutipolymer poda RDP/VAEinogona kuparadzirwa zvakare mu emulsion kana yasangana nemvura,polymer poda RDP/VAEiva chete ne dispersability yakanaka kuitira kuti uve nechokwadi chekushanda kwakanaka.polymer poda RDP/VAEinowanikwa mukuparadzirwa kazhinji hupfu huchena.

Zvisungo zvayo zvinosanganisira:

Polymer resin: iri muchikamu chepakati cheredispersible polymer podaparticles, zvakare ndicho chikamu chikuru chezve kudhispersiblepolymer poda RDP/VAEtamba basa.

Kuwedzera (mukati) : pamwe chete neresin kugadzirisa resin.

Kuwedzera (zvekunze) : zvimwe zvekuwedzera zvinowedzerwa kuti zviwedzere kuwedzera zvivakwa zvedispersiblepolymer poda RDP/VAE.

Protective colloid: dhizaini ye hydrophilic material yakaputirwa pamusoro peinorasika zvakarepolymer poda RDP/VAEzvimedu.Yakawanda yekudzivirira colloid ye redispersiblepolymer poda RDP/VAEinonzi polyvinyl doro.

Anti-caking agent: yakanaka mineral filler, inonyanya kushandiswa kudzivirira kubikwa kweredispersible polymer podamukugadzirisa kuchengetedza uye kutakura uye kufambisa kuyerera kweredispersible polymer poda(rasa kubva mubhegi rebepa kana tangi mota).
