Iipropati zePolymer Powder eDispersible Redispersible (RDP):

Ubungakanani beNcam: I-Redispersible Polymer Powder (RDP) ngokuqhelekileyo inomlinganiselo wamasuntswana ukusuka kwii-micrometers ezimbalwa ukuya kwishumi le-micrometers. Ubungakanani beengqungquthela ezincinci buqinisekisa ukusabalalisa okufanayo emanzini, ukuququzelela ukusetyenziswa kwabo kwiifom ezahlukeneyo.
Ukubunjwa kweMichiza: Ii-RDPs ngokuyinhloko zenziwe ngeepolymers zokwenziwa ezifana ne-polyvinyl acetate (PVA), i-polyvinyl alcohol (PVOH), i-ethylene vinyl acetate (EVA), kunye ne-acrylic polymers. Ezi polymers zinika iimpawu ezithile kumgubo, ezifana nokubambelela, ukuguquguquka, kunye nokumelana namanzi.
Ukunyibilika kwamanzi: Enye yeempawu eziphambili ze-RDPs kukukwazi ukusabalalisa kunye nokuchithwa emanzini, ukwenza i-colloidal suspension ezinzileyo. Le propati ibenza baguquguquke kakhulu kwimixube apho amanzi asisinyibilikisi sokuqala.
Ukuqulunqwa kwefilimu: Emva kokumisa, i-Redispersible Polymer Powder (RDP) yenza ifilimu edibeneyo, ehambelana ne-substrate surface. Le filimu ibonelela ngemisebenzi eyahlukeneyo ngokuxhomekeke kwisicelo esithile, njengokubopha, ukutywina, okanye ukugquma.
IiPropati zeRheological: Ii-RDP zinempembelelo kwindlela yokuziphatha ye-rheological yeenkqubo ezinamanzi, ezichaphazela izinto ezifana ne-viscosity, ukuhamba, kunye nokuzinza. Ulawulo olululo lwezi zakhiwo luyimfuneko ekufezekiseni umsebenzi ofunekayo wesicelo.
Inkqubo yokuVelisa:
Inkqubo yokwenziwa kweRedispersible Polymer Powder (RDP) ibandakanya izigaba ezininzi, kubandakanya i-polymer synthesis, i-emulsion polymerization, ukomisa, kunye nokusila.

I-Polymer Synthesis: Iipolima zokwenziwa ziqhele ukwenziwa ngokusabela kweekhemikhali ezibandakanya iimonomers. Ukukhethwa kwee-monomers kunye neemeko zokusabela kugqiba iipropati ze-polymer ezibangelwayo.
I-Emulsion Polymerization: Kule nkqubo, ukuphendulwa kwe-polymerization kwenzeka kwi-emulsion enamanzi, apho i-monomers ihlakazwe emanzini isebenzisa i-surfactants okanye i-emulsifiers. I-polymerization initiators ibangela ukusabela, okukhokelela ekubunjweni kweepolymer particles ezimisiwe kwi-emulsion.
Ukomisa: I-emulsion equkethe i-polymer particles ixhomekeke ekomisweni, apho amanzi asuswe khona ukufumana ubunzima obuqinileyo bepolymer. Iindlela ezahlukeneyo zokomisa ezinjengokomisa isitshizi, ukomisa umkhenkce, okanye ukomisa i-oveni zingasetyenziswa.
Ukugaya: Ubunzima bepolymer obomileyo buculwa bube ngamasuntswana acolekileyo ukuze kuphunyezwe ubungakanani obufunwayo. Amatye okusila okanye amatye okucoca asetyenziswa ngokuqhelekileyo kule njongo.

Usetyenziso lwePolymer Powder eDispersible (RDP):

Ukwakhiwa: Ii-RDPs zisetyenziswa kakhulu kwizinto zokwakha ezifana nokunamathiswa kweethayile, i-grouts, i-self-leveling compounds, kunye ne-cementitious renders. Baphucula ukubambelela, ukuguquguquka, kunye nokumelana namanzi kolu qulunqo, ukuphucula ukusebenza kwabo kunye nokuqina.
Iipeyinti kunye neeNgqungquthela: Kwimiqulu yepeyinti, i-Redispersible Polymer Powder (RDP) isebenza njengezibophelelo, inikezela ukunamathela, ukuqina, kunye nokuchasana nokukhuhla kwifilimu yokugqoka. Zikwasetyenziswa kwii-primers, sealants, kunye ne-elastomeric coatings.
Uqulunqo lwamachiza: Ii-RDPs zifumana usetyenziso kwimixube yoxubo-mayeza olufana neepilisi ezikhutshwayo ezilawulwayo, iithambiso zamachiza, kunye nokunqunyanyiswa ngomlomo. Basebenza njengeejenti ezenza ifilimu, izizinzi, okanye izinto zematrix, ezivumela ukukhutshwa kweziyobisi ezilawulwayo kunye nokuphuculwa kwe-bioavailability.
IiMveliso zoNonophelo boMntu: I-Redispersible Polymer Powder (RDP) ifakwe kwiimveliso zokhathalelo lomntu ezifana neegels zokulungisa iinwele, i-creams, kunye ne-lotions ukunika ulawulo lwe-rheological, ukuzinza, kunye neepropati zokwenza ifilimu.
Imizi-mveliso yelaphu kunye nePhepha: Ekugqityweni kwempahla kunye nokufakwa kwephepha, ii-RDPs zomeleza ukuqina kwelaphu, ukuxhathisa ukukrazuka, ukuprinta, kunye nokuguda komphezulu.
