Redispersible poda chinhu chakakosha chekuwedzera chinoshandiswa mune cementitious kana gypsum-based zvinhu muindasitiri yekuvaka. Kushandiswa kwaro kwakashandura nzira iyo zvinhu izvi zvinoshandiswa pakuvaka, sezvo inovandudza unhu hwechigadzirwa chekupedzisira, zvichiita kuti chigare chakasimba, chishanduke, uye chisingagoni kukuvadzwa nemvura. Muchikamu chino, tichatarisa kushandiswa kwakasiyana-siyana kwehupfu hunodzokororwa.

1. Kuvandudza kunamatira uye kubatana

Imwe yemashandisirwo makuru ehupfu inodispersible ndeye kuvandudza kunamatira uye kubatana kwecementitious kana gypsum-based zvinhu. Kana yakawedzerwa kumusanganiswa wakaoma, poda inogadziriswa inoumba firimu pamusoro pezvikamu zvesimenti, iyo inovandudza kukwanisa kwavo kunamatira pamwe chete uye kusungirirwa kune dzimwe nzvimbo. Izvi zvinonyanya kukosha mumashandisirwo apo zvinhu zvinoratidzwa kune masimba ekunze, semhepo kana mvura.

2. Kuwedzera kudzivirira kwemvura

Kumwe kushandiswa kwakakosha kwehupfu hunodzoreredzwa kukwidziridza kuramba kwemvura kwecementitious kana gypsum-based materials. Iyo firimu yepolymer inogadzirwa nehupfu inodzoreredzwa inodzivirira mvura kuti isapinda pamusoro pechinhu, izvo zvinoderedza njodzi yekutsemuka, kuderera, kana kudonha. Izvi zvinoita kuti zvinhu zvive zvakasimba uye zvinogara kwenguva refu, kunyangwe munzvimbo dzakanyorova kana dzine hunyoro.

3. Kuwedzera kushanduka uye kushanda

Redispersible poda inoshandiswawo kuwedzera kuchinjika uye kushanda kwecementitious kana gypsum-based materials. Iyo polymer firimu inogadzirwa nehupfu inodzoreredzwa inobvumira zvinhu kukotama uye kutambanudza pasina kutsemuka, izvo zvinoita kuti ive yakakodzera kushandiswa mumashandisirwo anotarisirwa kufamba. Iyo hupfu inowedzera kushanda kwechinhu, zvichiita kuti zvive nyore kusanganisa, kuparadzira, uye kupedza.

4. Kuvandudza chando-thaw resistance

Freeze-thaw resistance chinhu chakakosha checementitious kana gypsum-based materials, kunyanya munzvimbo dzine tembiricha dzinochinja zvakanyanya. Redispersible poda inogona kuvandudza kutonhora-kunyungudutswa kwezvishandiso izvi nekudzikisa huwandu hwemvura inopinda pamusoro pechinhu, izvo zvinoderedza njodzi yekutsemuka kana spalling.

5. Kuwedzera kusimba

Redispersible poda inoshandiswa kuwedzera kusimba kwecementitious kana gypsum-based zvinhu, zvichiita kuti zvisarambe kupfeka uye kubvaruka. Iyo poda inobatsira kusimbisa zvinhu, kuderedza njodzi yekutsemuka kana kuputika, uye kuwedzera hupenyu hwayo.

6. Kuwedzera chitarisiko

Redispersible poda inogona zvakare kusimudzira kutaridzika kwecementitious kana gypsum-based zvinhu, nekuvandudza magadzirirwo avo, ruvara, uye kupera. Iyo poda inogona kushandiswa kugadzira nzvimbo yakatsetseka, yakafanana, iyo inonyanya kukosha mumashandisirwo ayo zvinhu zvichange zvichionekwa, senge yekushongedza plaster kana stucco.

7. Kuderedza shrinkage

Redispersible poda inogona kubatsira kuderedza kuwanda kwe shrinkage inoitika mune cementitious kana gypsum-based zvinhu panguva yekuomesa. Izvi zvinodaro nekuti firimu repolymer rakaumbwa nehupfu rinobatsira kubata zvimedu pamwe chete, kuderedza huwandu hwenzvimbo pakati pazvo sezvo zvinhu zvaoma.

8. Kuwedzera simba

Redispersible poda inogona zvakare kuwedzera kusimba kwecementitious kana gypsum-yakavakirwa zvinhu, zvichiita kuti zvirambe zvichiramba kutyora kana kupaza mukushushikana. Upfu hunobatsira kusimbisa zvinhu, kuwedzera simba rayo uye kudzivirira kubva pakuputsika kana kuputsika.

9. Kuvandudza kushanda

Redispersible poda inogona kuvandudza kushanda kwecementitious kana gypsum-based zvinhu, zvichiita kuti zvive nyore kusanganisa, kuparadzira, uye kupedza. Iyo poda inoderedza huwandu hwemvura inodiwa mumusanganiswa, izvo zvinoita kuti zvinhu zvisanyanya kumhanya uye zviri nyore kudzora.

10. Kuwedzera kupikisa kumakemikari

Redispersible poda inogona kuwedzera kuramba kwecementitious kana gypsum-based zvinhu kumakemikari, akadai seasidhi kana alkalis. Iyo poda inobatsira kuchengetedza zvinhu kubva pamigumisiro yemakemikari aya, kuderedza dambudziko rekuora kana kuora.

Mukupedzisa, redispersible poda chinhu chakakosha chekuwedzera chinoshandiswa mune cementitious kana gypsum-based zvinhu muindasitiri yekuvaka. Kushandiswa kwaro kunowedzera zvinhu zvechigadzirwa chekupedzisira, zvichiita kuti chive chakasimba, chinoshanduka, uye chinopesana nekukuvara kwemvura. Iyo poda inoshandiswa kunatsiridza kunamatira uye kubatana, kuwedzera kusamira kwemvura, kuwedzera kuchinjika uye kushanda, kunatsiridza kutonhora-kunyungudika kuramba, kuwedzera kusimba, kuwedzera chitarisiko, kuderedza shrinkage, kuwedzera simba, kunatsiridza kushanda, uye kuwedzera kuramba makemikari.
