Inganda zubwubatsi zihora zitera imbere kandi hategurwa udushya n’ikoranabuhanga kugira ngo birusheho kuba byiza. Kimwe muri ibyo bishya ni ugukoresha ifu ya polymer idasubirwaho mubicuruzwa bya polymer. Ifu ya polymer isubirwamo ikoreshwa nka binders mugukora ibyo bicuruzwa. Ni ifu yera yabonetse na emulion polymerisation ya monomers. Ifu noneho itunganyirizwa muri polymer ishobora guhindurwa byoroshye mumazi. Isupu ya polymer isubirwamo ifite ibintu bitandukanye bituma iba binderi nziza kubicuruzwa bya polymer. Muri iki kiganiro, turasesengura uruhare rwifu ya polymer ikwirakwizwa mubicuruzwa bya polymer minisiteri n'impamvu bisaba guhinduka cyane.
Ibyiza bya pisitori ya redxersible
Ifu ya polymer isubirwamo ifite ibintu byinshi bituma ikoreshwa mubicuruzwa bya polymer. Kimwe mu bintu by'ingenzi bigize ifu nubushobozi bwabo bwo kunoza ibicuruzwa no guhinduka. Ni ukubera ko ifu igizwe nuduce twa polymer twahagaritswe mumazi. Iyo ifu ivanze namazi, ikora emulisiyo ihamye ishobora gukoreshwa muburyo bworoshye. Amazi amaze guhinduka, uduce twa polymer duhurira hamwe kugirango dukore firime ikomeza ihuza ibicuruzwa na substrate.
Undi mutungo wifu ya polymer ukwirakwizwa ni ukurwanya amazi. Ifu ni hydrophobique, bivuze ko isubiza amazi. Ibi bituma polymer mortar ibicuruzwa birwanya amazi cyane, bikabuza guturika no kwangirika iyo bahuye nubushuhe. Uyu mutungo kandi utuma ibicuruzwa biramba kuko bishobora kwihanganira kumara igihe kinini kumazi.
Redispersible latex powder nayo ifite ibintu byiza bifata neza. Ikora isano ikomeye hagati ya minisiteri na substrate, itezimbere imikorere rusange yibicuruzwa. Uyu mutungo ni ingenzi cyane kubicuruzwa bya polymer minisiteri kubisabwa hanze kuko bigomba kuba bishobora guhangana nikirere kibi.
Kuki ibicuruzwa bya polymer bikenera guhinduka cyane
Ibicuruzwa bya polimeri birimo ifu ya polymer isubirwamo bisaba guhinduka cyane kuko bikunze gukoreshwa mubikorwa byo hanze bigaragaramo ibidukikije bitandukanye. Ibi bintu birashobora gutuma substrate yaguka kandi igasezerana, bikaviramo gucikamo ibicuruzwa no kwangirika. Kubwibyo, guhinduka gukomeye birasabwa kugirango ibicuruzwa bishobore kwihanganira izo mbaraga bitavunitse cyangwa ngo bimeneke.
Ibicuruzwa bya polimeri birimo ifu ya polymer isubirwamo nabyo bikoreshwa mubikorwa byimbere byerekanwe no kunyeganyega no guhungabana. Muri ibi bihe, birahinduka cyane kugirango harebwe niba ibicuruzwa bishobora kwihanganira izo mbaraga bitavunitse cyangwa ngo bivunike. Ihinduka ryinshi naryo rigira uruhare mubikorwa rusange byibicuruzwa kuko ryemerera guhuza na substrate no kugumana imbaraga zabyo mubitutu.
Redispersible latex ifu nigice cyingenzi mugukora ibicuruzwa bya polymer. Imiterere yacyo itandukanye ifata neza kubicuruzwa, kuko byongera imiterere yabyo, bikongera amazi, kandi bikaramba muri rusange. Ibicuruzwa bya polimeri birimo ifu ya polymer isubirwamo bigomba kuba byoroshye guhinduka cyane cyane kubikorwa byo hanze byerekeranye nibidukikije bitandukanye kimwe nibisabwa imbere byerekanwa no kunyeganyega no guhungabana. Hamwe ninyungu zabo nyinshi, ifu ya polymer itatanye ihindura isura yinganda zubaka muguhindura uburyo ibikoresho byubwubatsi bikozwe, bikavamo ibicuruzwa byiza kandi biramba.
