I-Redispersible Emulsion Powder (RDP) ngokuqhelekileyo iqulunqwe ngamacandelo amaninzi abalulekileyo, ngalinye lisebenzela injongo ethile ekuqulunqweni. Ngelixa ukwakheka okuchanekileyo kunokwahluka ngokuxhomekeke kumvelisi kunye nesicelo esicetywayo, amacandelo aphambili e-RDP abandakanya:

1. Isiseko sePolymer: Inxalenye ephambili ye-RDP yipolymer yokwenziwa, eyenza umqolo we powder. Eyona polymer eqhelekileyo esetyenziswa kwi-RDP yi-vinyl acetate-ethylene (VAE) copolymer. Ezinye iipolymers ezifana nevinyl acetate-vinyl versatate (VA/VeoVa) copolymers, i-ethylene-vinyl chloride (EVC) copolymers, kunye neepolima ze-acrylic nazo zinokusetyenziswa ngokuxhomekeke kwiipropati ezifunwayo.
2. I-Protective Colloids: I-RDP isenokuba ne-colloids ekhuselayo efana ne-cellulose ethers (umzekelo, i-hydroxypropyl methylcellulose), i-polyvinyl alcohol (PVA), okanye isitashi. Ezi colloids zinceda ukuzinzisa i-emulsion ngexesha lokuvelisa kunye nokugcinwa, ukukhusela i-coagulation okanye i-sedimentation ye-polymer particles.
3. Iiplastiki: Iiplastiki zongezwa kwiifom ze-RDP ukuphucula ukuguquguquka, ukusebenza, kunye nokubambelela. Iiplastiki eziqhelekileyo ezisetyenziswa kwi-RDP ziquka i-glycol ethers, i-polyethylene glycols (PEGs), kunye ne-glycerol. Ezi zongezo zinceda ukwandisa ukusebenza kunye neempawu zokusetyenzwa kweRDP kwizicelo ezahlukeneyo.
4. Ii-Agents ezisasazayo: Ii-agent zokusabalalisa zisetyenziselwa ukuqinisekisa ukusabalalisa okufanayo kunye nokuphinda kuphinde kuphinde kuphinde kuphinde kuphinde kuphinde kuphinde kuphinde kuphinde kuphinde kuphinde kuphinde kubekho amasuntswana e-RDP emanzini. Ezi arhente ziphucula ukumanzisa kunye nokusasazeka kwepowder kwiinkqubo ezinamanzi, okuvumela ukuba kube lula ukufakwa kwiifom kunye nokuphucula ukuzinza kwezinto ezibangelwa yi-dispersions.
5. IiFillers and Additives: I-RDP formulations inokuba ne-fillers kunye ne-additives efana ne-calcium carbonate, i-silica, i-kaolin, okanye i-titanium dioxide. Ezi zongezo zinceda ukuphucula ukusebenza, ukuthungwa, kunye nokubonakala kweRDP kwizicelo ezithile. Zisenokusebenza njengezandisi okanye izongezo ezisebenzayo zokuphucula iipropathi ezinje nge-opacity, ukuqina, okanye irheology.
6. Ii-Arhente eziSebenzayo kwi-Surface Active: Ii-arhente ezisebenza kumphezulu okanye ii-surfactants zinokongezwa kwimixube ye-RDP ukuphucula ukumanzisa, ukusasazwa, kunye nokuhambelana namanye amacandelo ekuxutyweni. Ezi arhente zinceda ukunciphisa uxinzelelo lomphezulu kunye nokukhuthaza ukusebenzisana phakathi kwamaqhekeza e-RDP kunye nendawo ejikelezileyo, iqinisekisa ukusabalalisa okufanayo kunye nokusebenza okusebenzayo kwizicelo.
7. Ii-Anti-foaming Agents: Ii-Anti-foaming agents zingabandakanywa kwi-RDP formulations ukukhusela ukubunjwa kwegwebu ngexesha lokuvelisa okanye ukusetyenziswa. Ezi arhente zinceda ukunciphisa ukungena komoya kunye nokuphucula ukuzinza kunye nokuhambelana kwe-RDP ye-dispersions, ngokukodwa kwiinkqubo zokuxutywa kwe-shear ephezulu.
8. Ezinye izongezo: Ngokuxhomekeke kwiimfuno ezithile kunye neendlela zokusebenza ze-RDP formulations, ezinye izongezo ezifana ne-cross-linking agents, i-stabilizers, i-antioxidants, okanye i-colorants nayo ingabandakanywa. Ezi zongezo zinceda ukulungelelanisa iipropati kunye nokusebenza kwe-RDP kwizicelo ezithile kunye neemfuno zabasebenzisi bokugqibela.

amacandelo e-emulsion powder asebenza ngokudibeneyo ukubonelela ngeempawu ezinqwenelekayo ezifana nokunamathela, ukuguquguquka, ukuxhathisa kwamanzi, kunye nokusebenza kwizinto ezahlukeneyo zokwakha kunye nezicelo. Ukukhethwa kunye nokuqulunqwa kwala macandelo kubaluleke kakhulu ekufezekiseni ukusebenza kunye nomgangatho weemveliso zeRDP.
