I-Redispersible polymer powders (RDP) izongezo eziyimfuneko ezisetyenziswa kumashishini ahlukeneyo, ngakumbi kulwakhiwo, ekuphuculeni iipropati zezinto ezisekelwe kwisamente kunye nezinye izicelo. Nantsi isishwankathelo sepolymer powders ezinokuphinda zihlakazwe:

1. Ukwakheka:

• Iipolymer powders ezinokuphinda zenziwe kwakhona ngokwesiqhelo zenziwe ngeentlaka zepolymer, iiplasticizers, ii-agent ezichithachithayo, kunye nezinye izongezo.
• Iipolymer eziphambili ezisetyenziswa kwi-RDPs zihlala ziyi-copolymer ye-vinyl acetate kunye ne-ethylene (VAE), nangona ezinye iipolymers ezifana ne-acrylics nazo zingasetyenziswa.

2. Inkqubo yeMveliso:

• Ukuveliswa kweepolymer powders eziphinda ziphindwe kwakhona kubandakanya i-emulsion polymerization ye-monomers ukwenza i-polymer dispersions.
• Emva kokuba i-polymerization, amanzi asuswe kwi-dispersion ukuze avelise i-polymer eqinile kwifom yomgubo.
• I-powder ephumayo iphinda iqhutywe ngakumbi ukuphucula i-dispersibility yayo kunye neempawu zokuhamba.

3. Iinkcazelo ngeempawu:

• Iipolymer powders eziphinda zihlakazwe zihamba ngokukhululekileyo, zichithwa ngokulula ezinokuxutywa ngokulula namanzi ukwenza ukusasazwa okuzinzileyo.
• Zineempawu ezibalaseleyo zokwenza ifilimu kunye nokubambelela kwii-substrates ezahlukeneyo, ezizenza zilungele ukusetyenziswa kwizicelo ezininzi.
• Ii-RDPs ziphucula ukuguquguquka, ukuxhathisa kwamanzi, ukuqina, kunye nokusebenza kwezinto ezisekelwe kwi-samente ezifana nodaka, i-tile adhesives, kunye ne-self-leveling compounds.

4. Usetyenziso:

• Ishishini Lokwakha: Ii-RDPs zisetyenziswa kakhulu kwiimveliso zesamente ezifana nokuncamathelisa iithayile, iigrouts, iikhompawundi ezizilinganisa ngokwazo, ii-external insulation and finish systems (EIFS), kunye nenwebu ezithintela amanzi ukuze ziphucule iimpawu nokusebenza kwazo.
• Iipeyinti kunye neeNgxoxo: Ii-RDPs zisetyenziselwa izibophelelo, i-thickeners, kunye ne-film-forming agents kwiipeyinti ezisekelwe emanzini, iingubo, kunye ne-sealants ukuphucula ukubambelela, ukuguquguquka, kunye nokuqina.
• Umqhaphu: Ii-RDPs ziqeshwe kwiingubo zokwaleka kwaye zigqibezela ukomeleza iipropathi zelaphu ezifana nokugxothwa kwamanzi, ukuxhathisa amabala, kunye nokuxhathisa imibimbi.
• Iphepha kunye nokuPakisha: Ii-RDPs zisetyenziselwa ukugqoka amaphepha kunye ne-adhesives ukuphucula amandla, ukuprintwa, kunye neempawu zokuthintela.

5. Izinto eziluncedo:

• Ukunamathela okuPhuculweyo: Ii-RDPs zonyusa ukuncamathelwa kwezixhobo zesamente kwiisubstrates ezahlukeneyo, kubandakanya ikhonkrithi, iinkuni, intsimbi kunye neplastiki.
• Ukwandiswa kwe-Flexibility: I-RDPs iphucula ukuguquguquka kunye nokuxhatshazwa kwe-crack yezinto ezisekelwe kwi-samente, ezenza zibe zizinzileyo kwaye zixhathise ukuguqulwa.
• Ukuxhathisa Amanzi: Ii-RDPs zibonelela ngeempawu zokugxotha amanzi kunye nokuthintela amanzi kwiimveliso zesamente, zinciphisa ukufunxwa kwamanzi kunye nokomeleza ukomelela.
• Ukusebenza: I-RDPs iphucula ukusebenza kunye nokusasazeka kwezinto ezisekelwe kwi-samente, okuvumela ukuba kube lula ukusetyenziswa kunye nokugqiba okungcono.

6. Iingqwalasela zokusingqongileyo:

• Uqulunqo oluninzi lwe-RDP lusekelwe emanzini kwaye lunobuhlobo nokusingqongileyo, lunegalelo kwimisebenzi yolwakhiwo oluzinzileyo.
• Ii-RDPs zinokunceda ukunciphisa impembelelo yokusingqongileyo yemisebenzi yokwakha ngokuphucula ukuqina kunye nobude bezinto zokwakha.

Isiphelo:

I-polymer powders ekwazi ukuphinda isetyenziswe idlala indima ebalulekileyo ekuphuculeni ukusebenza kunye neempawu zemathiriyeli esekwe kwisamente kumashishini ahlukeneyo. Ukuguquguquka kwazo, ukuqina, kunye neenzuzo zokusingqongileyo kuzenza zibe zizongezo ezixabisekileyo zokuphucula umgangatho kunye nokuzinza kweeprojekthi zokwakha kunye nezinye izicelo. Njengoko imfuno yokusebenza okuphezulu, izinto zokwakha ezihambelana nokusingqongileyo ziyaqhubeka zikhula, ukusetyenziswa kweepolymer powders eziphinda-phindayo zilindeleke ukuba zande, ziqhubele phambili ukutsha kunye nophuhliso kule ndawo.
