Redispersible polymer powder (RDP) ni copolymer ya vinyl acetate na Ethylene ikorwa muburyo bwo kumisha spray. Nibyingenzi byingenzi mubikorwa bitandukanye byubwubatsi, bitanga neza, guhuza no kuramba kubicuruzwa bishingiye kuri sima. Gukora ifu ya polymer isubirwamo irimo intambwe nyinshi.
1. Guhitamo ibikoresho bibisi:
Vinyl acetate-Ethylene copolymer: Ibikoresho nyamukuru bya RDP ni copolymer ya vinyl acetate na Ethylene. Iyi copolymer yatoranijwe kubwiza buhebuje bwo gufatira hamwe nubushobozi bwo kongera ubworoherane nubukomezi bwibikoresho bya sima.
2. Emulion polymerisation:
Igikorwa cyo kubyaza umusaruro gitangirana na emulion polymerisation, aho vinyl acetate na etylene monomers iba polymerized imbere yabatangije na stabilisateur.
Imisemburo ya emuliyoni igenzurwa neza kugirango ibone uburemere bwa molekile yifuzwa, ibigize, hamwe na kopi yimiterere.
3. Igisubizo no gukoporora:
Vinyl acetate na monomers ya Ethylene bifata imbere ya catalizator kugirango ikore copolymer.
Igikorwa cya copolymerisation ningirakamaro kugirango ubone polymers hamwe nibintu byifuzwa, harimo ibintu byiza byo gukora firime no kugarurwa.
4. Shira kumisha:
Emulion noneho ikorerwa uburyo bwo kumisha spray. Ibi bikubiyemo gutera emulsiyo mucyumba gishyushye, aho amazi aguruka, hasigara uduce duto twa polymer idasubirwaho.
Koresha uburyo bwo kumisha, nkubushyuhe nubushyuhe bwo mu kirere, bigenzurwa neza kugirango habeho ibice byifu yubusa.
5. Kuvura hejuru:
Ubuvuzi bwubuso bukoreshwa kenshi mugutezimbere ububiko no guhinduranya ifu ya polymer.
Hydrophobique yongeramo cyangwa colloide ikingira ikoreshwa muburyo bwo kuvura hejuru kugirango hirindwe uduce duto no kongera ifu ikwirakwizwa mumazi.
6. Kugenzura ubuziranenge:
Ingamba zikomeye zo kugenzura ubuziranenge zishyirwa mubikorwa mubikorwa byose. Ibipimo nkubunini bwikwirakwizwa, ubwinshi bwinshi, ibinyabuzima bya monomer bisigaye hamwe nubushyuhe bwikirahure bikurikiranwa kugirango ibicuruzwa bihamye.
7. Gupakira:
Ifu yanyuma ya redispersible polymer yapakiwe mubintu bitarimo amazi kugirango birinde amazi, bishobora kugira ingaruka mbi kumikorere yabyo.
Porogaramu ya Redispersible Polymer Powder:
RDP ikoreshwa muburyo butandukanye bwubwubatsi burimo ibyuma bifata amatafari, ibingana-kwishyiriraho ibice, sisitemu yo kurangiza hanze (EIFS) na sima ya sima.
Ifu yongerera imbaraga nko kurwanya amazi, guhinduka no gufatira hamwe, bifasha kunoza imikorere rusange nigihe kirekire cyibikoresho byubaka.
mu gusoza:
Redispersible polymer powder nibikoresho byinshi bifite akamaro gakomeye mubikorwa byubwubatsi. Umusaruro wacyo urimo guhitamo neza ibikoresho fatizo, polymerisiyasi ya emulsiyo, kumisha spray, kuvura hejuru hamwe ningamba zikomeye zo kugenzura ubuziranenge.
Gukora ifu ya polymer isubirwamo ni inzira igoye isaba ubwitonzi no kwitondera amakuru arambuye kugirango ubone ibicuruzwa byujuje ubuziranenge hamwe nibintu bisabwa mubikorwa byo kubaka.
