I-Redispersible Polymer Powder (RDP) iyi-polymer esetshenziswa ezinhlotsheni ezahlukene zokusebenza. I-RDP iyi-powder encibilika emanzini eyenziwe ngama-polymer ahlukahlukene, okuhlanganisa i-vinyl acetate, i-vinyl acetate ethylene, nama-acrylic resins. I-powder ixutshwa namanzi nezinye izithasiselo ukuze kwakhiwe i-slurry, bese ifakwa kuma-substrate ahlukene. Kunezinhlobo eziningana ze-RDP, ngayinye inezakhiwo zayo ezihlukile kanye nokusetshenziswa kwayo. Kulesi sihloko, sizohlola ezinye zezinhlobo ezivame kakhulu ze-RDP kanye nezinhlelo zazo zokusebenza.
1. I-vinyl acetate i-polymer ephinde ihlakazeke
Ama-polymer aphinde ahlakazeke nge-vinyl acetate uhlobo oluvame kakhulu lwe-RDP. Enziwe nge-vinyl acetate kanye ne-vinyl acetate ethylene copolymer. Izinhlayiya ze-polymer zihlakazeka emanzini futhi zingaphinde zihlanganiswe zibe yisimo soketshezi. Lolu hlobo lwe-RDP lunezinhlelo zokusebenza eziningi ezifaka phakathi ama-mortar axutshwe okomile, imikhiqizo yesamente kanye nama-compounds azilinganisayo. Anikeza ukunamathela okuhle kakhulu, ukuguquguquka kanye nokuqina.
2. I-polymer ephinde ihlakazeke nge-acrylic
Ama-polymer aphinde ahlakazeke nge-acrylic enziwe ngama-copolymer e-acrylic noma e-methacrylic. Amandla awo angavamile kanye nokumelana nokuklwebheka kuwenza afanele ukusetshenziswa lapho ukuqina kubaluleke kakhulu. Asetshenziswa kuma-adhesive amathayili, izinhlelo zokushisa zangaphandle kanye nokuqeda (i-EIFS), kanye nokulungisa ama-mortar.
3. I-polymer ephinde ihlakazeke ye-ethylene-vinyl acetate
Ama-polymer aphinde ahlakazeke e-ethylene-vinyl acetate enziwe ngama-copolymer e-ethylene-vinyl acetate. Asetshenziswa ezinhlotsheni ezahlukene zezicelo okuhlanganisa ama-mortar esimende, ama-grout kanye nama-adhesive ethayela. Anokuguquguquka okuhle kakhulu kanye nokunamathela ukuze asetshenziswe ezindaweni ezicindezeleke kakhulu.
4. I-polymer ephinde ihlakazeke nge-styrene-butadiene
Ama-polymer aphinde ahlakazeke nge-styrene-butadiene enziwe ngama-copolymer e-styrene-butadiene. Asetshenziswa ezinhlotsheni ezahlukene zokusebenza okuhlanganisa nokulungisa ukhonkolo, izinamathiseli zamathayela kanye nama-grout. Anezindawo ezinhle kakhulu zokumelana namanzi kanye nezindawo zokunamathela.
5. Impuphu ye-polymer ephinde ihlanganiswe
Impuphu ye-polymer ephinde ihlanganiswe kabusha iyi-RDP eyenzelwe ukuhlanganiswa kabusha emanzini ngemva kokomiswa. Isetshenziswa ezindaweni eziningi lapho umkhiqizo uvezwa emanzini noma umswakama ngemva kokusetshenziswa. Lokhu kufaka phakathi izinamathiselo zamathayili, i-grout, kanye ne-caulk. Zinokumelana okuhle kakhulu namanzi kanye nokuguquguquka.
6. Impuphu ye-polymer ephinde ihlakazeke emanzini
Izimpushana ze-polymer eziphinde zihlakazeke emanzini ezenzelwe ukwandisa ukumelana kwamanzi kwemikhiqizo esekelwe kusimende. Ngokuvamile zisetshenziswa ezicelweni lapho umkhiqizo uzothintana namanzi, njenge-Exterior Insulation and Finishing Systems (EIFS), izinamathiselo zamathayela echibini lokubhukuda kanye nezimbotshana zokulungisa ukhonkolo. Zinokumelana kwamanzi okuhle kakhulu nokuqina.
I-Redispersible latex powder iyinto eguquguqukayo engasetshenziswa ezinhlotsheni eziningi. Kunezinhlobo eziningana ze-RDP, ngayinye inezakhiwo zayo ezihlukile kanye nokusetshenziswa kwayo. Ukunamathela kwazo okuhle kakhulu, ukuguquguquka nokuqina kuzenza zilungele ukusetshenziswa emikhiqizweni eyahlukahlukene. Uma zisetshenziswa kahle, zingasiza ekuthuthukiseni ikhwalithi kanye nobude bemikhiqizo eminingi yokwakha.
