RDP yo kwishyiriraho ibice

Isubirwamoifu ya polymer RDP / VAEni umubyimba mwinshi wa plaster shingiro-kuringaniza minisiteri yimikorere ningirakamaro yongeyeho, binyuze mubizaminiIsubirwamo ifu ya polymer RDP / VAEku gipimo cyinshi cyingaruka zumubiri nubukanishi bwa gypsum base yo kwipimisha minisiteri, kandi binyuze mubisesengura rya microscopique byagaragayeIsubirwamo ifu ya polymer RDP / VAEkunoza imiterere yubukanishi bwa gypsum ishingiro ryo-kuringaniza minisiteri yibikorwa, sobanura Redispersibleifu ya polymer RDP / VAEmuruhare rwa gypsumu ishingiye kurwego rwo hejuru.

Isubirwamoifu ya polymer RDP / VAEni ikoreshwa cyane kama kama ishobora kunoza imiterere yububiko bwa gypsumu.Ibisubizo byubushakashatsi byerekana ko amazi yambere yo kwisuzumisha ya minisiteri yibyibushye bya gypsumu yiyongera mbere hanyuma bikagabanuka hamwe no kwiyongera kwivanga ryifu ya kole.Impamvu nuko ifu ya kole ifite ububobere runaka mumazi yashonze.Iyo kuvanga amafaranga ari make, kwiyongera kwijimye rya slurry bitezimbere ubushobozi bwo guhagarika ibituba byuzuza, bifasha mugutemba kwa slurry.Iyo ibirimo ifu ya rubber ikomeje kwiyongera, kwiyongera kwijimye ryijimye biganisha ku kwiyongera kwijimye ryinshi no kugabanuka kwamazi.Ingano yifu ya kole ntigira ingaruka nke kuri 20min fluidity ya minisiteri.

Isubirwamoifu ya polymer RDP / VAEnk'ubwoko bwa organic binder, ubukana bwiterambere buterwa no guhumeka kwamazi atemba, imbaraga zubusabane, firime ikora ifuru yumye yumye yumye, gypsumu ishingiye kumyuka ya minisiteri irashobora gukora firime ikomeza, ikagira umurunga mwiza hamwe nimbaraga zumye. ya gypsumu ishingiye ku kwipimisha minisiteri irimo ifu iriyongera.

UtongeyehoIsubirwamo ifu ya polymer RDP / VAEgira gypsumu nyinshi ishingiye kurwego rwo kwipimisha minisiteri, inkingi ya dihydrate ya gypsum ya kristu hamwe no gupakira bidasanzwe Hagati ya dihydrate gypsum kristal na dihydrate gypsum kristal na crisscross guhuzagurika hagati yo gupakira hamwe, binyuze muburyo budasanzwe bipakiye hamwe bikora gypsumu ishingiye ku kwipima imbaraga za minisiteri, wongeyehoIsubirwamo ifu ya polymer RDP / VAEgypsumu ishingiye kurwego rwo kwipimisha,Isubirwamo ifu ya polymer RDP / VAEku ishingwa rya gypsumu ishingiye ku kwishyira hejuru ya mortar filamentous ihuza, kristu ya dihydrate ya gypsum no gupakira, ikiraro kama kama hagati ya kristu na kirisiti, firime ngenga ikorwa kuri kristu ya dihydrate, ibice byuzuzanya hagati ya dihydrate gypsum ya kristu no guhuza, ongeraho guhuriza hamwe kwa gypsumu ishingiye ku kwipimisha minisiteri n'imbaraga zifatika, Kunoza imbaraga za gypsumu ishingiye ku kwipimishaIsubirwamo ifu ya polymer RDP / VAEmuri minisiteri hamwe na membrane, irashobora kunonosora ubumwe bwa minisiteri yumye nimbaraga zumubano, ifu hagati ya kristu ya dihydrate gypsum na paki yerekana ibintu bigize kristu ya dihydrate gypsum nubusabane bukomeye bikozwe hagati yuzuza no kunoza ubumwe hagati ya kristu ya dihydrate na paki. , Rero, imbaraga zubusabane bwa gypsum base yo-kuringaniza minisiteri itezimbere macroscopically.
