I-Redispersible polymer powders (RDP) iyizithasiselo ezibalulekile ezisetshenziswa ezimbonini ezahlukahlukene, ikakhulukazi ezakhiweni, zokuthuthukisa izakhiwo zezinto ezisekelwe kusimende nezinye izinhlelo zokusebenza. Nakhu ukubuka konke kwezimpushana ze-polymer ezihlakazeka kabusha:

1. Ukwakhiwa:

• Izimpushana ze-polymer ezihlakazeka kabusha zivame ukwakhiwa ngama-polymer resins, ama-plasticizers, ama-agent ahlakazayo, nezinye izithasiselo.
• I-polymer eyinhloko esetshenziswa kuma-RDPs ngokuvamile i-copolymer ye-vinyl acetate ne-ethylene (VAE), nakuba amanye ama-polymers afana nama-acrylics angasetshenziswa.

2. Inqubo Yokukhiqiza:

• Ukukhiqizwa kwezimpushana ze-polymer ezihlakazeka kabusha kuhilela i-emulsion polymerization yama-monomers ukuze enze ama-polymer dispersions.
• Ngemuva kwe-polymerization, amanzi asuswa ekuhlakazweni ukuze kukhiqizwe i-polymer eqinile ngesimo sempushana.
• Impushana ewumphumela bese icutshungulwa ngokuqhubekayo ukuze kuthuthukiswe i-redispersibility yayo kanye nezindawo zokugeleza.

3. Izakhiwo:

• Izimpushana ze-polymer ezihlakazeka kabusha zigeleza mahhala, izimpushana ezihlakazeka kalula ezingaxutshwa kalula namanzi ukuze zakhe ukuhlakazeka okuzinzile.
• Zinezakhiwo ezinhle kakhulu zokwenza ifilimu nokunamathela kuma-substrates ahlukahlukene, okubenza bafanelekele ukusetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza.
• Ama-RDP athuthukisa ukuguquguquka, ukumelana namanzi, ukuqina, kanye nokusebenza kwezinto ezisekelwe kusimende ezifana nodaka, izinto zokunamathisela zamathayili, nezinhlanganisela zokuzilinganisa.

4. Izicelo:

• Imboni Yezokwakha: Ama-RDP asetshenziswa kakhulu emikhiqizweni kasimende efana nezinamatheliso zamathayela, ama-grouts, izinhlanganisela ezizilinganisa, amasistimu angaphandle kanye nama-finishing systems (EIFS), kanye nolwelwesi oluvimbela amanzi ukuze kuthuthukiswe izakhiwo nokusebenza kwawo.
• Opende Nezimbotshana: Ama-RDP asetshenziswa njengezibophezelo, izingqimba, kanye nama-ejenti enza ifilimu kumapende asekelwe emanzini, ama-coatings, nama-sealant ukuze kuthuthukiswe ukunamathela, ukuguquguquka, nokuqina.
• Izindwangu: Ama-RDP asetshenziswa embotsheni yendwangu futhi aqedele ukuthuthukisa izakhiwo zendwangu ezifana nokuxosha amanzi, ukumelana namabala, kanye nokumelana nokushwabana.
• Iphepha Nokupakishwa: Ama-RDP asetshenziswa embotsheni yephepha nezinamatheliso ukuze kuthuthukiswe amandla, ukuphrinta, kanye nezakhiwo zokuvimbela.

5. Izinzuzo:

• Ukunamathela Okuthuthukisiwe: Ama-RDP athuthukisa ukunamathela kwezinto zikasimende kuma-substrates ahlukahlukene, okuhlanganisa ukhonkolo, ukhuni, insimbi, nepulasitiki.
• Ukuguquguquka Kwenyuka: Ama-RDP athuthukisa ukuguquguquka nokumelana nokuqhekeka kwezinto ezisekelwe kusimende, azenze ziqine futhi zimelane nokuguquguquka.
• Ukumelana Namanzi: Ama-RDP anikeza izinto zokuxosha amanzi kanye nezindawo zokuvikela amanzi emikhiqizweni kasimende, ehlisa ukumuncwa kwamanzi futhi athuthukisa ukuqina.
• Ukusebenza kahle: Ama-RDP athuthukisa ukusebenza nokusabalala kwezinto ezisekelwe kusimende, okuvumela ukusetshenziswa okulula nokuqedwa okungcono.

6. Ukucatshangelwa kwemvelo:

• Izindlela eziningi zokwakhiwa kwe-RDP zisekelwe emanzini futhi zinobungani nemvelo, zinomthelela ezinhlelweni zokwakha ezisimeme.
• Ama-RDP angasiza ukunciphisa umthelela wemvelo wemisebenzi yokwakha ngokwenza ngcono ukuqina nokuphila isikhathi eside kwezinto zokwakha.

Isiphetho:

Izimpushana ze-polymer ezihlakazeka kabusha zidlala indima ebalulekile ekuthuthukiseni ukusebenza nezakhiwo zezinto ezisekelwe kusimende ezimbonini ezihlukahlukene. Ukuguquguquka kwazo, ukuqina, kanye nezinzuzo zemvelo kuzenza izengezo ezibalulekile zokuthuthukisa ikhwalithi nokusimama kwamaphrojekthi wokwakha nezinye izinhlelo zokusebenza. Njengoba isidingo sokusebenza okuphezulu, izinto zokwakha ezinobungani bemvelo ziqhubeka nokukhula, ukusetshenziswa kwezimpushana ze-polymer ezihlakazeka kabusha kulindeleke ukuthi kwande, kuqhubekisele phambili ukuqamba okusha nentuthuko kulo mkhakha.
