Ifu ya Emulsion isubirwamo ni iki?
Ifu ya Redispersible emulsion (RDP), izwi kandi nka redispersible polymer powder, nuburyo bwifu ya polymer ishingiye kumazi. Ubusanzwe ikorwa no gutera kumisha ivangwa rya polymer ikwirakwizwa, mubisanzwe bishingiye kuri vinyl acetate-Ethylene (VAE) cyangwa vinyl acetate-vertile (VAC / VeoVa) copolymers, hamwe ninyongeramusaruro zitandukanye nka colloide ikingira, surfactants, na plastike.
Dore uko ifu ya emulsion isubirwamo ikorwa nibiranga ibintu byingenzi:
Uburyo bwo kubyaza umusaruro:
- Polymer Emulsion: Emulion ya polymer itegurwa na polymerizing monomers nka vinyl acetate, Ethylene, nabandi ba comonomers imbere yamazi na emulisiferi. Ubu buryo butuma habaho uduce duto twa polymer dukwirakwizwa mumazi.
- Ongeraho inyongeramusaruro: Inyongeramusaruro nka colloide ikingira, surfactants, na plasitike irashobora kongerwaho kuri emulsiyo kugirango ihindure imiterere n'imikorere.
- Kuma Kuma: Emulion ya polymer noneho igaburirwa mumashanyarazi, aho iba atomike mumatonyanga meza hanyuma ikuma ikoresheje umwuka ushushe. Amazi amaze guhinduka, ibice bikomeye bya polymer, bikavamo ifu itemba yubusa.
- Gukusanya no gupakira: Ifu yumye ikusanyirizwa munsi yumuti wa spray, ikayungurura kugirango ikureho ibice byose binini, hanyuma igapakirwa kubika no gutwara.
Ibintu by'ingenzi biranga:
- Ingano ya Particle: Ifu isubirwamo ya emulsion isanzwe igizwe nuduce duto twa sherfike hamwe na diametre kuva kuri micrometero nkeya kugeza kuri micrometero icumi, bitewe nuburyo bwihariye bwo gukora no kubikora.
- Kugabanuka kw'amazi: Kimwe mu bintu by'ingenzi biranga RDP ni ubushobozi bwayo bwo gutembera mu mazi kugira ngo habeho emulisiyo ihamye iyo ivanze n'amazi. Ibi bituma byoroha kwinjizwa mumazi ashingiye kumazi nka minisiteri, amavuta, hamwe na coatings.
- Ibirimo bya Polymer: RDP muri rusange irimo ibintu byinshi bya polymer, mubisanzwe kuva kuri 50% kugeza 80% kuburemere, bitewe n'ubwoko bwa polymer bwihariye.
- Ibigize imiti: Ibigize imiti ya RDP biratandukana bitewe nubwoko bwa polymer yakoreshejwe nibindi byongeweho byinjizwa mugihe cyo gukora. Polimeri zisanzwe zikoreshwa muri RDP zirimo vinyl acetate-Ethylene (VAE) copolymers hamwe na vinyl acetate-itandukanye (VAC / VeoVa) copolymers.
- Ibyiza byimikorere: RDP itanga ibintu byinshi byifuzwa muburyo bwo gukora, harimo guhuza neza, guhinduka, kurwanya amazi, no kuramba. Itezimbere imikorere, imbaraga zubukanishi, nigikorwa cyibikoresho bitandukanye byubwubatsi nka minisiteri, ibyuma bifata amabati, gushushanya, hamwe no kwishyira hamwe.
Muri make, ifu ya emulsion isubirwamo (RDP) nuburyo butandukanye bwifu ya polymers ishingiye kumazi ya polymeri ikoreshwa nkinyongera mubikorwa bitandukanye byubwubatsi nibikorwa byinganda. Ubushobozi bwayo bwo gutembera mumazi, ibintu byinshi bya polymer, hamwe nibikorwa byifuzwa bikora bigira uruhare runini mugutegura ibikoresho byubaka byujuje ubuziranenge kandi biramba.
