Nigute ifu ya polymer isubirwamo bigira ingaruka kumiterere ya minisiteri?

Kwivanga bigira ingaruka nziza mukuzamura imikorere yo kubaka minisiteri yumye. Ifu ya redispersible latex ikorwa no gutera spray yumuti udasanzwe wa polymer. Ifu yumye ya polymer yumye ni 80 ~ 100mm ya serefegitire yegeranye hamwe. Ibi bice byoroshye gushonga mumazi, bigakora ikwirakwizwa rihamye rinini cyane ugereranije nuduce twambere twa emulioni, hanyuma tugakora firime nyuma yo kubura umwuma no gukama.

Ingamba zinyuranye zo guhindura zituma ifu ya redxersible latx ifite ibintu bitandukanye nko kurwanya amazi, kurwanya alkali, kurwanya ikirere no guhinduka. Ifu ya redxersible latex ya minisiteri irashobora kunoza ingaruka zo guhangana ningaruka, kuramba, kwihanganira kwambara, korohereza ubwubatsi, imbaraga zubusabane hamwe no guhuriza hamwe, guhangana nikirere, kurwanya ubukonje-gukonjesha, kurwanya amazi, imbaraga zoroshye no kurwanya imbaraga za minisiteri. Igihe cyose ibikoresho bishingiye kuri sima birimo ifu ya latex ihuye namazi, reaction ya hydration izatangira, kandi calcium hydroxide ya calcium izahita yuzura kandi ikorwe. Icyarimwe, kristu ya ettringite na calcium silicate hydrate geles zirakorwa. Ibice bikomeye bishyirwa kuri gel hamwe na sima idafite amazi. Iyo reaction ya hydration igenda itera imbere, ibicuruzwa biva mumazi biriyongera, kandi ibice bya polymer bigenda byegeranya buhoro buhoro mu mwobo wa capillary, bigakora igiteranyo cyinshi cyo gukusanya hejuru ya gel hamwe na sima idafite amazi. Ibikoresho bya polymer byegeranijwe byuzura buhoro buhoro.

Ifu ya redispersible latex irashobora kunoza imbaraga zo kugonda no guhuza imbaraga za minisiteri kuko irashobora gukora firime ya polymer hejuru yubutaka bwa minisiteri. Hano hari imyenge hejuru ya firime, kandi hejuru ya pore huzuyemo minisiteri, bigabanya guhangayika. Kandi bizaruhuka bitavunitse munsi yibikorwa byimbaraga zo hanze. Byongeye kandi, minisiteri ikora skeleti ikomeye nyuma ya sima ihinduwe, na polymer muri skeleton ifite imikorere yingingo zimuka, zisa nuduce twumubiri wumuntu. Ururenda rwakozwe na polymer rushobora kugereranywa ningingo hamwe na ligaments, bityo bigatuma ubworoherane nubworoherane bwa skeleton ikomera.

Muri polymer-yahinduwe na sima ya minisiteri, firime ikomeza kandi yuzuye ya polymer ihujwe na sima paste hamwe nuduce twumucanga, bituma minisiteri yose iba nziza, kandi icyarimwe bigatuma umuyoboro wose wa elastike wuzuza capillaries na cavites. Kubwibyo, firime ya polymer irashobora kwanduza neza umuvuduko nuburemere bworoshye. Filime ya polymer irashobora gukuraho ibice bigabanuka kuri polymer-mortar, gukiza ibice byo kugabanuka, no kunoza kashe no guhuza imbaraga za minisiteri. Kubaho kwa polymer bihindagurika cyane kandi byoroshye cyane bya polymer byongera ubworoherane nubworoherane bwa minisiteri, bitanga ubumwe hamwe ningirakamaro kuri skeleton ikomeye. Iyo imbaraga zo hanze zashyizwe mubikorwa, inzira yo gukura ya microcrack iratinda kugeza igihe impagarara nyinshi zigeze kubera ubwiyongere bworoshye na elastique. Imiyoboro ya polymer ihuriweho nayo ikora nkimbogamizi ya microcrack kugirango ihuze mubice byinjira. Kubwibyo, ifu ya polymer isubirwamo yongerera imbaraga kunanirwa no kunanirwa kwibikoresho.
