Redispersible polymer poda chinhu chakakosha chekuwedzera chinoshandiswa mune cementitious kana gypsum-based zvinhu muindasitiri yekuvaka. Iyo poda inogadzirwa nekupfapfaidza-kuomesa polymer dispersion, iyo inogadzira yakasununguka-inoyerera poda inogona kusanganiswa nyore nyore nezvimwe zvakaoma zvinoshandiswa. Kune akati wandei akasiyana marudzi ezve dispersible polymer poda inowanikwa, imwe neimwe iine yayo yakasarudzika zvimiro uye hunhu. Muchikamu chino, tichatarisa mamwe emhando dzinowanzo zivikanwa redispersible polymer poda.

1. Vinyl acetate-ethylene (VAE) redispersible polymer powder

VAE redispersible polymer poda ndeimwe yemhando dzinowanzo shandiswa redispersible polymer poda muindasitiri yekuvaka. Inogadzirwa ne polymerizing vinyl acetate uye ethylene mumvura-based emulsion, iyo inobva yapfapfaidzwa-yakaomeswa kugadzira poda inoyerera yakasununguka. VAE redispersible polymer poda inozivikanwa nekunamira kwayo kwakanakisa, kuchinjika, uye kuramba kwemvura, zvichiita kuti ive yakanakira kushandiswa mumashandisirwo uko kusimba kwakakosha, sekugadziriswa kwekongiri, kunamatira mataira, uye kuvharira kwekunze uye kupedza masisitimu (EIFS).

2. Vinyl acetate-based redispersible polymer poda

Vinyl acetate-based redispersible polymer powder inogadzirwa ne polymerizing vinyl acetate mumvura-based emulsion, iyo inobva yapfapfaidzwa-yakaomeswa kuti igadzire hupfu hunoyerera. Rudzi urwu rwepolymer poda inodhindwa zvakare inozivikanwa nekunamira kwayo kwakanaka, kushanda kwayo, uye kunyungudika kwechando, ichiita kuti ive yakakodzera kushandiswa mumashandisirwo akadai sepurasita, stucco, uye yekushongedza.

3. Acrylic-based redispersible polymer poda

Acrylic-based redispersible polymer powder inogadzirwa ne polymerizing acrylic monomers mumvura-based emulsion, iyo inobva yapfapfaidzwa-yakaomeswa kugadzira hupfu hunoyerera. Acrylic-based redispersible polymer poda inozivikanwa nekunaka kwayo kwemvura kuramba, kunamatira, uye kuchinjika, zvichiita kuti ive yakakodzera kushandiswa mumashandisirwo akadai segrout, kugadzirisa kongiri, uye anonamira mataira.

4. Styrene-butadiene-based (SBR) redispersible polymer powder

SBR redispersible polymer poda inogadzirwa ne polymerizing styrene uye butadiene mumvura-based emulsion, iyo inobva yapfapfaidzwa-yakaomeswa kugadzira hupfu husina kuyerera. SBR redispersible polymer poda inozivikanwa nekuchinjika kwayo, kunamatira, uye kuramba kwemvura, zvichiita kuti ive yakanakira kushandiswa mumashandisirwo akaita sedhaka, grout, uye kugadzirisa kongiri.

5. Ethylene-vinyl chloride (EVC) redispersible polymer powder

EVC redispersible polymer powder inogadzirwa ne polymerizing ethylene uye vinyl chloride mumvura-based emulsion, iyo inobva yapfapfaidzwa-yakaomeswa kugadzira hupfu hunoyerera mahara. EVC redispersible polymer poda inozivikanwa nekunamira kwayo mvura, kunamatira, uye kuchinjika, zvichiita kuti ive yakakodzera kushandiswa mumashandisirwo akadai seanonamira mataira, kugadzirisa kongiri, uye EIFS.

6. Redispersible polymer poda ine yakagadziridzwa starch

Redispersible polymer poda ine yakagadziridzwa starch inogadzirwa nekuwedzera yakagadziridzwa starch kumvura-based emulsion isati yapfapfaidza-kuomesa. Iyo yakagadziridzwa starch inoshanda seanoparadzira, inobatsira kudzikamisa emulsion uye kuvandudza redispersibility yehupfu. Rudzi urwu rwepolymer poda inodhindwa inozivikanwa nekunamira kwayo, kushanda nesimba, uye kuramba mvura, zvichiita kuti ive yakakodzera kushandiswa mumashandisirwo akaita sedhaka, grout, uye plaster.

7. Redispersible polymer poda ine cellulose ether

Redispersible polymer poda ine cellulose ether inogadzirwa nekuwedzera cellulose ether kumvura-based emulsion isati yapfapfaidza-kuomesa. Iyo cellulose ether inoshanda seyakakora, inovandudza kushanda kwehupfu uye kuderedza huwandu hwemvura inodiwa mumusanganiswa. Rudzi urwu rwepolymer poda inodhindwa inozivikanwa nekunamira kwayo, kushanda, uye kuchengetedza mvura, zvichiita kuti ive yakakodzera kushandiswa mumashandisirwo akadai semataira anonamira, grout, uye simende yekudzivirira mvura membranes.
