Mvura isingapindi mvura inoreva dhaka resimende rine zvakanaka kusapinda mvura uye kusapinda mvura mushure mekuoma nekugadzirisa reshiyo yedhaka uye kushandisa hunyanzvi hwekuvaka. Mvura isingapindi dhaka ine kumira kwemamiriro ekunze kwakanaka, kusimba, kusamira, compactness uye yakanyanya kunamatira pamwe nekusimba kwemvura uye anti-corrosion mhedzisiro. Kushandiswa kwepolymer poda inodispersible sechinhu chikuru chekuwedzera mudhaka isingapinde mvura kwavandudza zvakanyanya kuita kwese kwedhaka risina mvura, zvichiita kuti ive chimwe chezvinhu zvakakosha muzvirongwa zvekuvaka.
Kushandiswa kwepoda inodzokororwa mudhaka isingapinde mvura kunonyanya kuratidza Mune zvinotevera zvinhu:
Isingapindi mvura uye inopesana nepeji: Iyo poda inodhindwa inogona kuzadza pores mudhaka, ichiita dense isina mvura mudhaka, kudzivirira kupinda kwemvura uye kugadzirisa kusapinda kwemvura kwese kwedhaka layer.
Simba rekubatanidza rakasimba: Redispersible polymer poda inogona kuwedzera kubatana uye kunamatira pakati pedhaka uye base layer, zvichiita kuti dhiri remvura riwedzere kusimba uye kushoma kudonha.
Freeze-thaw kuramba: redispersible polymer poda inogona kubatsira kuvandudza kutonhora-kunyunguduka kwedhaka, zvichiita kuti ive yakakodzera kune akasiyana mamiriro ekunze; redispersible polymer poda inogona kuvandudza zvakanyanya simba rekusimba redhaka, zvichiita kuti dhaka rirambe rakasimba. Nokuwedzera kubatana kwemukati uye viscosity yedhaka, simba rose revhu rinovandudzwa.
Kuva nyore kwekuvaka: Redispersible polymer poda inogona kukurumidza kunyungudutswa mumvura inotonhora uye inogona kuvandudza maitirwo ekuita kwesamende dhaka, iyo inobatsira kudzora zvirinani maitiro ekuvaka edhaka nekuvandudza kushanda kwekuvaka.
Mhedzisiro yekudzoreredzwa kwepolymer poda pane nyowani isina mvura dhaka:
A、 Kuvandudza kushanda;
B, Kuwedzera kuchengetedza mvura, kunatsiridza simende hydration;
Mhedzisiro pakuomesa dhaka risina mvura:
A, Deredza iyo elastic modulus yedhaka uye wedzera kuenderana kwayo nekuenderana ne base layer;
B, Wedzera kuchinjika uye kuramba kuputika;
C, Kuvandudza dhaka density;
D, Hydrophobia;
E, Wedzera kunamatira.
