I-Redispersible Polymer Powder (RDP) iyi-polymer esetshenziswa ezintweni ezahlukahlukene. I-RDP iyimpushana encibilika emanzini eyenziwe ngama-polymer ahlukahlukene, okuhlanganisa i-vinyl acetate, i-vinyl acetate ethylene, nama-acrylic resins. Impushana ixubene namanzi nezinye izithasiselo ukuze kwakhiwe i-slurry, bese isetshenziswa kuma-substrates ahlukene. Kunezinhlobo eziningana ze-RDP, ngayinye enezindawo zayo ezihlukile kanye nokusetshenziswa kwayo. Kulesi sihloko, sizohlola ezinye zezinhlobo ezivame kakhulu ze-RDP kanye nezicelo zazo.
1. I-vinyl acetate redispersible polymer
I-Vinyl acetate redispersible polymers wuhlobo oluvame kakhulu lwe-RDP. Zenziwe nge-vinyl acetate ne-vinyl acetate ethylene copolymer. Izinhlayiya ze-polymer zihlakazeka emanzini futhi zingaphinde zibuyiselwe esimweni se-liquid. Lolu hlobo lwe-RDP lunezinhlobonhlobo zezinhlelo zokusebenza ezihlanganisa udaka lwengxube eyomile, imikhiqizo kasimende kanye nezinhlanganisela zokuzilinganisa. Banikeza ukunamathela okuhle kakhulu, ukuguquguquka nokuqina.
2. I-Acrylic redispersible polymer
I-Acrylic redispersible polymers yenziwe nge-acrylic noma i-methacrylic copolymers. Amandla azo angavamile kanye nokumelana nokuhuzuka kuzenza zilungele izinhlelo zokusebenza lapho ukuqina kubaluleke kakhulu. Asetshenziswa kuma-adhesives we-tile, insulation yangaphandle kanye nezinhlelo zokuqeda (EIFS), kanye nokulungisa ama-mortars.
3. I-ethylene-vinyl acetate redispersible polymer
I-Ethylene-vinyl acetate redispersible polymers yenziwe ngama-copolymers e-ethylene-vinyl acetate. Asetshenziswa ezinhlobonhlobo zezicelo ezihlanganisa udaka lukasimende, ama-grouts nama-adhesives we-tile. Zinokuguquguquka okuhle kakhulu nokunamathela ukuze zisetshenziswe ezindaweni ezicindezela kakhulu.
4. I-Styrene-butadiene redispersible polymer
I-styrene-butadiene redispersible polymers enziwe ngama-copolymers e-styrene-butadiene. Zisetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezihlanganisa udaka lokukhanda ukhonkolo, izinamatheliso zamathayili nama-grouts. Banokumelana okuhle kwamanzi kanye nezakhiwo zokunamathela.
5. Impushana ye-polymer egaywe kabusha
I-polymer powder e-emulsifiable kabusha iyi-RDP eklanyelwe ukufakwa kabusha emanzini ngemva kokoma. Isetshenziswa ezinhlelweni eziningi lapho umkhiqizo uvezwa khona emanzini noma umswakama ngemva kokusetshenziswa. Lezi zihlanganisa okunamathelisa amathayili, i-grout, ne-caulk. Banokumelana okuhle kwamanzi nokuguquguquka.
6. I-Hydrophobic redispersible polymer powder
I-Hydrophobic redispersible polymer powders eklanyelwe ukukhulisa ukumelana namanzi kwemikhiqizo esekwe usimende. Ngokuvamile isetshenziswa ezinhlelweni lapho umkhiqizo uzohlangana khona namanzi, njenge-Exterior Insulation and Finishing Systems (EIFS), izinto zokunamathisela zamathayela echibini lokubhukuda nezinsimbi zokulungisa ukhonkolo. Inokumelana namanzi okuhle kakhulu kanye nokuqina.
Redispersible latex powder iyimpahla eguquguqukayo engasetshenziswa ezinhlelweni eziningi. Kunezinhlobo eziningana ze-RDP, ngayinye enezindawo zayo ezihlukile kanye nokusetshenziswa kwayo. Ukunamathela kwazo okuhle kakhulu, ukuguquguquka nokuqina kwazo kuzenza zilungele ukusetshenziswa emikhiqizweni ehlukahlukene. Uma zisetshenziswe ngendlela efanele, zingasiza ukuthuthukisa ikhwalithi nokuphila isikhathi eside kwemikhiqizo eminingi yokwakha.
