I-polymer powder e-redispersible iyisengezo esibalulekile esisetshenziswa ezintweni ezisekelwe ku-cementitious noma ze-gypsum embonini yezokwakha. Impushana yenziwa ngokufafaza i-polymer dispersion, eyenza impushana egeleza mahhala engaxutshwa kalula nezinye izithako ezomile. Kunezinhlobo eziningana ezahlukene zempushana ye-polymer ehlakazeka kabusha etholakalayo, ngayinye enezici zayo nezici ezihlukile. Kulesi sigaba, sizobheka ezinye zezinhlobo ezivame kakhulu ze-polymer powder ehlakazeka kabusha.

1. I-Vinyl acetate-ethylene (VAE) i-polymer powder ehlakazeka kabusha

I-VAE redispersible polymer powder ingenye yezinhlobo ezivame ukusetshenziswa kakhulu ze-polymer powder ehlakazeka embonini yezokwakha. Yenziwe nge-polymerizing vinyl acetate kanye ne-ethylene ku-emulsion esekwe emanzini, bese ifafazwa ukuze idale impushana egeleza mahhala. I-VAE redispersible polymer powder yaziwa ngokunamathela kwayo okuhle kakhulu, ukuguquguquka, kanye nokumelana namanzi, okuyenza ilungele ukusetshenziswa ezinhlelweni lapho ukuqina kubaluleke khona, njengokukhanda ukhonkolo, ukunamathiswa kwamathayela, kanye nezinhlelo zangaphandle zokugquma nokuqeda (EIFS).

2. I-vinyl acetate-based redispersible polymer powder

I-Vinyl acetate-based redispersible polymer powder yenziwe nge-polymerizing vinyl acetate ku-emulsion esekwe emanzini, bese ifafazwa ukuze yenze impushana egeleza mahhala. Lolu hlobo lwempushana ye-polymer ehlakazeka kabusha lwaziwa ngokunamathela kwayo okuhle kakhulu, ukusebenza kahle, kanye nokumelana nokuncibilika, okulenza ilungele ukusetshenziswa ezintweni ezifana ne-plaster, istucco, nezingubo zokuhlobisa.

3. I-Acrylic-based redispersible polymer powder

I-Acrylic-based redispersible polymer powder yenziwa nge-polymerizing acrylic monomers ku-emulsion esekwe emanzini, bese ifafazwa ukuze yenze impushana egeleza mahhala. I-Acrylic-based redispersible polymer powder yaziwa kakhulu ngokumelana namanzi, ukunamathela, nokuguquguquka, okuyenza ilungele ukusetshenziswa ezinhlelweni ezifana ne-grout, ukulungisa ukhonkolo, nokunamathela kwamathayela.

4. I-styrene-butadiene-based (SBR) i-polymer powder ehlakazeka kabusha

I-SBR redispersible polymer powder yenziwa nge-polymerizing styrene ne-butadiene ku-emulsion esekwe emanzini, bese ifafazwa ukuze kwakhiwe impushana egeleza mahhala. I-SBR redispersible polymer powder yaziwa ngokuguquguquka kwayo okuhle kakhulu, ukunamathela, nokumelana namanzi, okuyenza ilungele ukusetshenziswa ezinhlelweni ezinjengodaka, i-grout, nokulungisa ukhonkolo.

5. I-Ethylene-vinyl chloride (EVC) i-polymer powder ehlakazeka kabusha

I-EVC redispersible polymer powder yenziwa nge-polymerizing ethylene kanye ne-vinyl chloride ku-emulsion esekwe emanzini, bese ifafazwa ukuze kwakhiwe impushana egeleza mahhala. I-EVC redispersible polymer powder yaziwa ngokumelana kwayo okuhle kakhulu namanzi, ukunamathela, nokuguquguquka, okuyenza ilungele ukusetshenziswa ezinhlelweni ezifana nokunamathiswa kwamathayili, ukulungisa ukhonkolo, kanye ne-EIFS.

6. I-polymer powder ehlakazeka kabusha enesitashi esishintshiwe

Impushana ye-polymer ehlakazeka kabusha enesitashi esishintshiwe yenziwa ngokungeza isitashi esiguquliwe ku-emulsion esekwe emanzini ngaphambi kokufutha-omiswe. I-starch eguquliwe yenza njenge-dispersant, isiza ukuzinzisa i-emulsion futhi ithuthukise i-dispersibility ye-powder. Lolu hlobo lwempushana ye-polymer ehlakazeka kabusha lwaziwa ngokunamathela kwayo okuhle kakhulu, ukusebenza kahle, nokumelana namanzi, okuyenza ilungele ukusetshenziswa ezintweni ezifana nodaka, i-grout, ne-plaster.

7. I-polymer powder ehlakazeka kabusha ene-cellulose ether

Impushana ye-polymer ehlakazeka kabusha ene-cellulose ether yenziwa ngokungeza i-cellulose ether ku-emulsion esekwe emanzini ngaphambi kokufutha-omiswe. I-cellulose ether isebenza njenge-thickener, ithuthukisa ukusebenza kwe-powder futhi inciphise inani lamanzi adingekayo ekuxubeni. Lolu hlobo lwempushana ye-polymer ehlakazeka kabusha lwaziwa ngokunamathela kwayo okuhle kakhulu, ukusebenza kahle, nokugcinwa kwamanzi, okulwenza lulungele ukusetshenziswa ezinhlelweni ezifana nokunamatheliswa kwamathayili, i-grout, nolwelwesi lukasimende oluvimbela amanzi.
