Redispersible polymer ifu yuburyo bwo gukora

Intangiriro

Ifu ya polymer isubirwamo (RDP) ni ubwoko bwifu ya polymer ishobora guhindurwa mumazi kugirango ikore emulisiyo ihamye. Ikoreshwa cyane mubikorwa byubwubatsi nkinyongera mugutezimbere imikorere yibikoresho bishingiye kuri sima. RDP ikorwa nuburyo buzwi nka spray-yumisha, burimo atomisation yumuti wa polymer mubifu nziza. Ifu noneho iruma hanyuma igasya kugeza kubunini bwifuzwa.

Ibikorwa byo gukora RDP bikubiyemo intambwe nyinshi, harimo guhitamo polymer, gutegura igisubizo, atomisation, gukama, no gusya. Ubwiza bwibicuruzwa byanyuma buterwa cyane nubwiza bwibikoresho fatizo hamwe nibikorwa bikoreshwa mugihe cyo gukora.

Guhitamo Polymer

Intambwe yambere mubikorwa byo gukora RDP nuguhitamo polymer ikwiye. Guhitamo polymer bishingiye kumiterere yifuzwa yibicuruzwa byanyuma, nko kurwanya amazi, gufatira hamwe, no guhinduka. Polimeri ikoreshwa cyane mubikorwa bya RDP ni vinyl acetate-Ethylene copolymers, acrylic copolymers, na styrene-butadiene copolymer.

Gutegura igisubizo

Iyo polymer imaze gutorwa, ihita ishonga mumashanyarazi kugirango ikemuke. Amashanyarazi akoreshwa cyane mu musaruro wa RDP ni amazi n’umuti kama nka Ethanol na isopropanol. Ubwinshi bwibisubizo bya polymer mubisanzwe hagati ya 10-20%.

Atomisation

Intambwe ikurikira mubikorwa byo gukora RDP ni atomisation. Atomisiyoneri ninzira yo kumena igisubizo cya polymer mubitonyanga bito. Ibi mubisanzwe bikorwa hakoreshejwe umuvuduko mwinshi wa nozzle cyangwa atomizeri izunguruka. Ibitonyanga noneho byumishwa mumazi ashyushye kugirango bibe ifu.

Kuma

Ifu noneho yumishwa mumazi ashyushye kugirango ikureho umusemburo. Uburyo bwo kumisha bukorwa mubushyuhe buri hagati ya 80-120 ° C. Igihe cyo kumisha giterwa nubwoko bwa polymer bwakoreshejwe, ubunini bwumuti, nubunini bwifuzwa.

Gusya

Intambwe yanyuma mubikorwa byo gukora RDP ni ugusya. Gusya ninzira yo gusya ifu mubunini buke. Mubisanzwe bikorwa hakoreshejwe urusyo rwinyundo cyangwa urusyo rwumupira. Ingano yibicuruzwa byanyuma mubisanzwe hagati ya microne 5-50.

Umwanzuro

Ifu ya polymer isubirwamo ni ubwoko bwifu ya polymer ishobora gusubizwa mumazi kugirango ibe emulisiyo ihamye. Ikoreshwa cyane mubikorwa byubwubatsi nkinyongera mugutezimbere imikorere yibikoresho bishingiye kuri sima. Ibikorwa byo gukora RDP bikubiyemo intambwe nyinshi, harimo guhitamo polymer, gutegura igisubizo, atomisation, gukama, no gusya. Ubwiza bwibicuruzwa byanyuma buterwa cyane nubwiza bwibikoresho fatizo hamwe nibikorwa bikoreshwa mugihe cyo gukora.
