Ifu ya polymer isubirwamo ningirakamaro zingirakamaro muri minisiteri yongerera ubworoherane, imbaraga zihuza hamwe nububiko bwamazi yibicuruzwa byanyuma. Nyamara, hari ubwoko bwinshi butandukanye bwa pisitori ya polymer isubirwamo, kandi guhitamo imwe ijyanye nibyo ukeneye birashobora kugorana.
Ubwa mbere, birakenewe gusobanukirwa uruhare rwifu ya polymer isubirwamo. Iki gicuruzwa ni kopolymer ya vinyl acetate na Ethylene, spray-yumye ivuye mumazi ya polymer. Ifu yagenewe kunoza imiterere ya minisiteri, cyane cyane muburyo bwo guhinduka, gukora, gufatira hamwe no gufata amazi. Byongeye kandi, iteza imbere sima nziza, igabanya ibyago byo guturika, kugabanuka no ivumbi.
Ibikurikira nibintu byingenzi ugomba gusuzuma muguhitamo neza ifu ya polymer isubirwamo ya minisiteri yawe.
Ubwoko bwa Mortar
Ikintu cya mbere ugomba gusuzuma ni ubwoko bwa minisiteri uteganya gukoresha. Hariho ubwoko bwinshi bwa minisiteri, harimo na sima ishingiye kuri sima, minisiteri ya lime cyangwa minisiteri ya gypsumu, na epoxy resin mortar. Buriwese ufite imiterere yihariye nibisabwa, bizagena ubwoko bwifu ya polymer isubirwamo. Amabuye ya sima niyo akunze kugaragara kandi arasaba ifu ya polymer idasubirwaho hamwe no gufata amazi meza, imbaraga zububiko hamwe nakazi.
Uburyo bwo gusaba
Uburyo bwo gusaba nabwo burakomeye muguhitamo ifu ya polymer isubirwamo. Ibicuruzwa bimwe byashizweho kugirango bikoreshwe mu kuvanga byumye, mugihe ibindi bikwiranye no kuvanga porogaramu. Mu kuvanga byumye, ifu ya polymer igomba kuba ishobora gutatana vuba kandi iringaniye kugirango ikore emulisiyo ihamye hamwe namazi. Mubivangavanze bitose, ifu ya polymer igomba kugira redispersibility kandi ikabasha kuvanga neza nibindi byongeweho na sima.
Ibisabwa
Imikorere isabwa na minisiteri nayo izagira uruhare muguhitamo ifu ya polymer isubirwamo. Porogaramu zitandukanye zikenera imbaraga zitandukanye, guhinduka no kuramba. Kurugero, niba ushaka gukora urukuta rwinyuma, uzakenera ibicuruzwa bifite amazi meza kandi birwanya ubukonje. Ubundi, niba ukoresha tile yometseho, ukenera ifu ya polymer isubirwamo hamwe nimbaraga nziza hamwe.
Ifu ya polymer
Ikindi kintu cyingenzi ugomba gusuzuma muguhitamo ifu ya polymer isubirwamo ni imikorere yibicuruzwa. Ibintu byingenzi byo gushakisha birimo ingano yubunini, ubushyuhe bwikirahure (Tg) nibirimo. Ingano yubunini bwifu ifata itandukaniro ryayo nimbaraga zo guhuza. Ingano ntoya (munsi ya 80μm) itanga amazi meza, mugihe ingano nini (irenga 250 mm) itanga imikorere myiza.
Ubushyuhe bwikirahure (Tg) bwifu ya polymer isubirwamo igena guhinduka kwayo. Tg hejuru yubushyuhe bwicyumba (25 ° C) bivuze ko ifu ikaze, mugihe Tg munsi yubushyuhe bwicyumba bivuze ko ifu yoroshye. Ifu ya polymer idasubirwaho ifite Tg nkeya (munsi ya -15 ° C) nibyiza mubihe bikonje aho minisiteri ishobora guhura nubukonje.
Ubwanyuma, ibinini birimo ifu ya polymer isubirwamo igena igipimo cyayo nogukoresha amazi asabwa kugirango avangwe. Ibikomeye cyane (hejuru ya 95%) bisaba ifu nkeya kugirango ugere kubintu byifuzwa, bivamo ibiciro bike no kugabanuka gake.
mu gusoza
Guhitamo iburyo bwa polymer isubirwamo ifu ya minisiteri ya minisiteri ningirakamaro kugirango ugere kubikorwa byifuzwa kandi biramba kubicuruzwa byanyuma. Urebye ubwoko bwa minisiteri, uburyo bwubwubatsi, ibisabwa mubikorwa nibiranga ifu ya polymer, urashobora guhitamo ibicuruzwa byujuje ibyifuzo byawe byihariye. Wibuke, gukoresha ifu ya polymer isubirwamo neza ntabwo bizamura imiterere ya minisiteri yawe gusa, ahubwo bizanagabanya ibyago byo guturika, kugabanuka no kuvumbi, bikavamo kuramba kuramba kandi kwiza.
