1. Basa reRedispersible latex podamu putty inonyanya mune zvinotevera zvinhu:

(1).Kuvandudza adhesion uye mechanical properties ye putty.Redispersible latex podaihupfu binder yakagadzirwa neakakosha emulsion (polymer) mushure mekupfapfaidza kuomeswa.Inonyanya kushandiswa ndeyeethylene-vinyl acetate copolymer.Iyi poda inogona kukurumidza kuparadzirwa mu emulsion mushure mekusangana nemvura, uye ine maitiro akafanana neyokutanga emulsion, kureva kuti, firimu inogona kuumbwa mushure mokunge mvura yapera.Iyi firimu ine kushanduka kwepamusoro, kupikisa kwemamiriro ekunze uye kunamatira kwepamusoro kune zvakasiyana-siyana zve substrates.Mukuwedzera, iyo latex poda ine hydrophobicity inogona kuita kuti dhaka rive rakanakakudzivirira mvurauye kuwedzera flexural simba.

(2).Kuvandudza kusapinda kwemvura uye kupera kweputty.

(3).Kuvandudza kuchengetwa kwemvura kweputty,kuwedzera nguva yekuvhura, uye kushanda.

(4).Kuvandudza kukanganisa kupikisa kweputty uye kuwedzera kusimba kweputty.

2. Basa reRedispersible latex podamudhaka rinonyanya mune zvinotevera zvinhu:

(1).Kuvandudza simba rekumanikidza uye kushanduka kwesimba redhaka.

(2).Kuwedzerwa kweRDP kunowedzera kurebesa kwedhaka, nekudaro kunatsiridza kusimba kwedhaka, uye panguva imwechete ichipa dhaka yakanaka yekuparadzira kusagadzikana.

(3).Kuvandudza kusungirirwa kwekuita kwedhaka.Iyo yekubatanidza nzira inotsamira pane adsorption uye kupararira kwema macromolecules pane inonamira pamusoro.Panguva imwecheteyo, RDP ine kumwe kupenya uye inopinda zvizere pamusoro peiyo base zvinhu pamwe chetecellulose ether, kuitira kuti zvinhu zvepamusoro zvechigadziko chepasi uye purasita itsva zviri pedyo, nokudaro kuvandudza adsorption uye kuwedzera zvakanyanya kushanda kwayo.

(4).Deredza elastic modulus yevhu, gadzirisa iyosimba deformation kukwanisa, uye kuderedza kuputika kwechiitiko.

(5).Kuvandudza abrasion resistance yedhaka.Kuvandudzwa kwekupokana kwekupfeka kunonyanya kukonzerwa nekuvapo kweimwe nhamba yerabha ridge pamusoro pedhaka, uye RDP inoita basa rekubatanidza, uye mesh chimiro chakaumbwa neRDP chinogona kupfuura nemumaburi uye kuputika mudhaka resimende. .Inovandudza kusungirirwa kwebinder kune simenti hydration chigadzirwa, nekudaro ichiwedzera kupfeka kuramba.

(6).Ipa iyo dhaka zvakanakisa alkali kuramba.

3. Basa reRedispersible latex podamumatairi anonamira zvakanyanya mune zvinotevera zvinhu:

(1).Mhedzisiro yekuwedzeraRedispersible latex podapadhaka ichangobva kusanganiswa yekunamira mataira:

A. Wedzera nguva dzekushanda uye nguva dzinogadziriswa;

B. Kuvandudza mashandiro ekuchengetedza mvura kuti ive nechokwadi chekuti simende hydration;

C. Kuvandudza sag resistance (special modified rubber powder);

D. Kuvandudza kushanda (zviri nyore kuvaka pane substrate).

(2).Mhedzisiro yekuwedzeraRedispersible latex podakune dhaka rakaomeswa rekunamatira mataira:

A. Iine kunamatira kwakanaka nema substrates akasiyana-siyana, kusanganisira kongiri, plaster, huni, mataira ekare, PVC;

B. Inokwanisa kuchinjika zvakanaka pasi pemamiriro ekunze akasiyana siyana.
