Akamaro ko kongeramo ifu ya polymer isubirwamo kuri gypsum yo-kuringaniza

Ongeraho 2% kugeza kuri 3% yifu ya redxersible latx irashobora kunoza cyane imyambarire yimyambarire ya minisiteri yonyine, ishobora guhura na 28d yo kwambara ≤ 0.59 iteganijwe mubisanzwe.Polimeri ikwirakwira muri minisiteri hanyuma ikora firime, yuzuza imyenge ya slurry kandi igahuza nibicuruzwa bitanga amazi ya sima kugirango ibe imiterere y'urusobekerane rw'imiterere itatu, ituma imiterere ya minisiteri irushaho gukomera.Filime yoroheje ya polymer ifasha kugabanya imihangayiko yimbere ya minisiteri, igabanya imihangayiko, kandi igabanya kubyara mikorobe, kandi iyi firime ya polymer ntabwo igira uruhare runini rwa hydrophobique ahubwo inabuza capillary, kugirango ibikoresho ifite hydrophobicity nziza no guhumeka.Muri icyo gihe, kubera ingaruka zo gufunga zatewe na firime ya polymer, ibikoresho bidashobora kwangirika kubushuhe, imiti irwanya imiti, kurwanya ubukonje, hamwe nigihe kirekire biratera imbere cyane, kandi imbaraga zunama, kurwanya ibimeneka, imbaraga zifatika, hamwe na elastique ya minisiteri iratunganijwe.Kandi gukomera, kandi amaherezo arashobora kwirinda kugabanuka kumeneka ya minisiteri.

Ubushakashatsi bwerekanye ko amazi ya mbere ya gypsumu yimbitse-yifashishije uburinganire bwa minisiteri yiyongera mbere hanyuma akagabanuka no kwiyongera kwifu ya poro ya latex.Impamvu nuko ifu ya latex ifite ububobere runaka mumazi yashonze.Ubushobozi bwo guhagarika ibishishwa byuzuza byatejwe imbere, bifitiye akamaro urujya n'uruza;iyo ingano yifu ya latex ikomeje kwiyongera, kwiyongera kwubwiza bwibisebe biganisha ku kwiyongera kwijimye ryikigina, kandi amazi yerekana inzira yo kumanuka.Ingano yifu ya latex nta ngaruka igira ku minota 20-min ya minisiteri.Nka bingo kama, ifu ya latex iterwa no guhinduka kwamazi mumazi, kandi firime ikora imbaraga zubusabane, kandi gypsum yibanze ubwayo murwego rwumye.Amazi yo muri minisiteri aragenda, kandi ifu ya latex irashobora gukora firime ikomeza, ifite imbaraga zifatika.Imbaraga zumye za gypsumu zishingiye ku kwipimisha minisiteri yiyongera hamwe no kwiyongera kwifu ya latex.Muri gypsumu ishingiye ku kwipimisha ubwayo idafite ifu ya latex, hariho umubare munini winkoni zimeze nkinkingi hamwe ninkingi ya dihydrate gypsum ya kristu hamwe na kristu ya dihydrate idasanzwe kandi hagati ya kristu ya dihydrate.Kurundanya hamwe kugirango gypsumu ishingiye ku kwipimisha ubwayo itanga imbaraga, hamwe na gypsum ishingiye ku kwipimisha minisiteri ivanze nifu ya redispersible latex, ifu ya latex ikora ihuriro rya filamentary muri gypsumu ishingiye kuri marimari, na dihydrate. kristu ya gypsumu niyuzuza, kristu Ikiraro kama gikozwe hagati ya kristu na dihydrate gypsum kristal, hanyuma hakorwa firime ngenga kuri dihydrate gypsum kristal kugirango ipfunyike kandi ihuze ibice byuzuzanya hagati ya kristu ya dihydrate, bityo byongere ubumwe no guhuriza hamwe ya gypsumu ishingiye ku kwipimisha no kuzamura imbaraga za pompe ya gypsumu ishingiye ku kwipimisha marike Ifu ya latex ifite imiterere yo gukora firime muri minisiteri, ishobora kunoza ubumwe no guhuza imbaraga za minisiteri yumye.Ishirwaho ryumubano mwiza hagati yuzuza utezimbere ubumwe hagati ya dihydrate gypsum kristal hamwe nuwuzuza, bityo bikazamura imbaraga zubusabane bwa gypsumu ishingiye ku kwipimisha minisiteri ya macroscopically.
