Nibihe bice bigize ifu ya emulsion isubirwamo
Redispersible Emulsion Powder (RDP) mubusanzwe igizwe nibice byinshi byingenzi, buri kimwe gikora intego yihariye mugutegura. Mugihe ibihimbano nyabyo bishobora gutandukana bitewe nuwabikoze nibisabwa, ibice byibanze bya RDP mubisanzwe birimo:
- Base ya Polymer: Igice cyingenzi cya RDP ni polymer synthique, ikora umugongo wifu. Polymer ikunze gukoreshwa muri RDP ni vinyl acetate-Ethylene (VAE) copolymer. Izindi polymers nka vinyl acetate-vinyl verisiyo (VA / VeoVa) copolymers, Ethylene-vinyl chloride (EVC) copolymers, na polymers ya acrylic nayo irashobora gukoreshwa bitewe nibintu wifuza.
- Kurinda ibibyimba birinda: RDP irashobora kuba irimo colloide ikingira nka ethers ya selile (urugero, hydroxypropyl methylcellulose), inzoga za polyvinyl (PVA), cyangwa krahisi. Iyi colloide ifasha guhagarika emuliyoni mugihe cyo kuyibyaza no kuyibika, ikarinda kwangirika cyangwa gutembera kwa polymer.
- Plastiseri: Plastiseri yongewe kumikorere ya RDP kugirango irusheho guhinduka, gukora, no gufatana. Amashanyarazi asanzwe akoreshwa muri RDP arimo glycol ethers, polyethylene glycols (PEGs), na glycerol. Izi nyongera zifasha guhindura imikorere no gutunganya ibiranga RDP mubikorwa bitandukanye.
- Ibikoresho byo gutatanya: Ibikoresho byo gukwirakwiza bikoreshwa kugirango habeho gutatanya kimwe no guhinduranya ibice bya RDP mumazi. Izi mikorere zongerera amazi no gukwirakwiza ifu muri sisitemu yo mu mazi, bigatuma byoroha kwinjizwa muburyo bworoshye no kunoza ituze ryaturutse.
- Ibyuzuza ninyongeramusaruro: Imiterere ya RDP irashobora kuba irimo ibyuzuza ninyongera nka calcium karubone, silika, kaolin, cyangwa dioxyde ya titanium. Izi nyongera zifasha kunoza imikorere, imiterere, nigaragara rya RDP mubikorwa byihariye. Bashobora kandi gukora nk'iyaguka cyangwa inyongeramusaruro ikora kugirango bongere imitungo nko kutagaragara, kuramba, cyangwa rheologiya.
- Ububiko bukora bwa Surface: Ibikoresho bikora neza cyangwa surfactants birashobora kongerwaho muburyo bwa RDP kugirango bitezimbere, gutatanya, no guhuza nibindi bice mubisobanuro. Izi mikorere zifasha kugabanya impagarara zubuso no guteza imbere imikoranire hagati ya RDP nuduce tuyikikije, kwemeza gutandukana kimwe no gukora neza mubisabwa.
- Ibikoresho birwanya ifuro: Ibikoresho birwanya ifuro birashobora gushyirwa mubikorwa bya RDP kugirango birinde ifuro mugihe cyo gukora cyangwa kubishyira mu bikorwa. Izi mikorere zifasha kugabanya kwinjiza ikirere no kunoza ituze no guhoraho kwa RDP, cyane cyane muburyo bwo kuvanga-shear.
- Ibindi byongeweho: Ukurikije ibisabwa byihariye nibipimo ngenderwaho byimikorere ya RDP, ibindi byongeweho nkibikoresho byambukiranya imipaka, stabilisateur, antioxydants, cyangwa amabara nabyo birashobora kubamo. Izi nyongeramusaruro zifasha guhuza imiterere nibikorwa bya RDP kubikorwa byihariye nibisabwa-umukoresha wa nyuma.
ibice bya pisitori ya emulsion isubirwamo ikora hamwe kugirango itange ibintu byifuzwa nko gufatira hamwe, guhinduka, kurwanya amazi, no gukora mubikoresho bitandukanye byubwubatsi nibisabwa. Guhitamo no gutegura ibyo bice nibyingenzi kugirango tugere ku mikorere myiza nubuziranenge mubicuruzwa bya RDP.
