Kodi ntchito ya ufa wa latex wopangidwanso ndi chiyani pakudziyimira pawokha pa gypsum?

Redispersible latex powder ndi chowonjezera chofunikira chomwe chimakhudza magwiridwe antchito a matope odziyimira pawokha a gypsum-based self-leveling.Chikoka cha re-dispersible latex ufa pa thupi ndi makina katundu wa wandiweyani wosanjikiza gypsum-based self-leveling matope amayesedwa, ndi redispersible latex ufa amawululidwa kudzera kusanthula microscopic.Mfundo yowongolera makina a matope odziyimira pawokha a gypsum akuwonetsa kuti ufa wopangidwanso wa latex umagwira ntchito yayikulu pakudzikweza kwa gypsum.

Redispersible latex powder ndi organic binder yomwe imagwiritsidwa ntchito kwambiri, yomwe imatha kupititsa patsogolo magwiridwe antchito akagwiritsidwa ntchito muzomangamanga za gypsum.Mayesero apeza kuti madzi oyambirira a matope a gypsum-based self-leveling matope amawonjezeka poyamba ndiyeno amachepetsa ndi kuwonjezeka kwa ufa wa latex.Chifukwa chake ndi chakuti ufa wa latex uli ndi viscosity inayake m'madzi osungunuka.Kuthekera kwa kuyimitsidwa kwa slurry kwa filler kumatheka, komwe kumapindulitsa pakuyenda kwa slurry;pamene kuchuluka kwa ufa wa latex kukupitirirabe, kuwonjezeka kwa viscosity ya slurry kumabweretsa kuwonjezeka kwa kukhuthala kwa slurry, ndipo madzi amadzimadzi amasonyeza kutsika.Kuchuluka kwa ufa wa latex sikumakhudza pafupifupi 20min fluidity ya matope.

Monga organic binder, mphamvu ya latex ufa imadalira kutuluka kwa madzi mu slurry, ndipo mphamvu ya mgwirizano imapangidwa ndi mapangidwe a filimu.M'malo owuma, madzi a gypsum-based self-leveling mortar amasanduka nthunzi, ndipo ufa wa latex ukhoza kupanga filimu yosalekeza.Kumamatira bwino, mphamvu youma ya gypsum-based self-leveling mortar imawonjezeka ndi kuchuluka kwa ufa wa latex.

Mu matope odziyimira pawokha a gypsum opanda ufa wa latex, pali makristalo ambiri owoneka ngati ndodo ndi columnar dihydrate gypsum crystals ndi makhiristo osakhazikika a dihydrate gypsum komanso pakati pa makhiristo a dihydrate gypsum ndi zodzaza.Mulunjike palimodzi kuti mupangire matope odziyimira pawokha opangidwa ndi gypsum kuti apange mphamvu, ndipo matope odziyimira pawokha opangidwa ndi gypsum osakanizidwa ndi ufa wa latex wopangidwanso, ufa wa latex umapanga kulumikizana kwa filamentary mu matope odziyimira pawokha, ndi dihydrate. gypsum makhiristo ndi fillers, makhiristo An organic mlatho aumbike pakati pa krustalo ndi dihydrate gypsum krustalo, ndi organic filimu aumbike pa dihydrate gypsum kristalo kukulunga ndi kulumikiza akuthwa mbali pakati pa dihydrate gypsum makhiristo, potero kuonjezera mgwirizano ndi kugwirizana. a gypsum-based self-leveling mortar ndi kupititsa patsogolo mphamvu ya gypsum-based self-leveling mortar The latex powder imakhala ndi mafilimu opanga mafilimu mumatope, omwe amatha kupititsa patsogolo mgwirizano ndi kugwirizanitsa mphamvu zamatope owuma.Kupanga kolumikizana kothandiza pakati pa zodzaza kumathandizira kulumikizana pakati pa makhiristo a gypsum a dihydrate ndi zodzaza, potero kumapangitsa kuti matope odziyimira pawokha azitha kukhazikika.
