Lub luag hauj lwm ntawm redispersible latex hmoov nyob rau hauv gypsum-based self-leveling yog dab tsi?

Redispersible latex hmoov yog ib qho tseem ceeb ntxiv uas cuam tshuam rau kev ua haujlwm ntawm tuab-txheej gypsum-based self-leveling mortar.Kev cuam tshuam ntawm re-dispersible latex hmoov nyob rau hauv lub cev thiab txhua yam khoom ntawm tuab-txheej gypsum-raws li tus kheej-leveling mortar yog sim, thiab cov redispersible latex hmoov yog qhia los ntawm microscopic tsom xam.Lub hauv paus ntsiab lus ntawm kev txhim kho cov khoom ntawm gypsum-based self-leveling mortar qhia tau hais tias redispersible latex hmoov plays lub luag haujlwm loj hauv gypsum-based self-leveling.

Redispersible latex hmoov yog siv dav siv hauv cov ntaub ntawv organic, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom thaum siv cov khoom siv hauv tsev gypsum.Kev sim tau pom tias qhov pib fluidity ntawm tuab-txheej gypsum-based self-leveling mortar nce ua ntej thiab tom qab ntawd txo qis nrog qhov nce ntawm cov hmoov latex.Yog vim li cas yog tias cov hmoov latex muaj qee yam viscosity hauv cov dej yaj.Lub peev xwm raug ncua ntawm slurry mus rau qhov muab tub lim yog txhim kho, uas muaj txiaj ntsig zoo rau kev khiav ntawm slurry;Thaum cov hmoov latex tseem nce ntxiv, qhov nce hauv qhov viscosity ntawm slurry ua rau muaj kev nce hauv cov viscosity ntawm slurry, thiab fluidity qhia tau hais tias ib qho kev poob qis.Tus nqi ntawm cov hmoov latex yuav luag tsis cuam tshuam rau 20min fluidity ntawm mortar.

Raws li cov organic binder, lub zog ntawm cov hmoov latex nyob ntawm cov evaporation ntawm cov dej hauv slurry, thiab lub zog daim ntawv cog lus yog tsim los ntawm kev tsim cov yeeb yaj kiab.Hauv lub xeev qhuav, cov dej hauv gypsum-based self-leveling mortar evaporates, thiab cov hmoov latex tuaj yeem tsim cov yeeb yaj kiab txuas ntxiv.Zoo dua adhesion, lub zog qhuav ntawm gypsum-based self-leveling mortar nce nrog qhov nce ntawm cov hmoov latex.

Nyob rau hauv gypsum-based self-leveling mortar tsis muaj latex hmoov, muaj ntau tus pas nrig-zoo li tus thiab columnar dihydrate gypsum crystals thiab tsis tu ncua muab tub lim dihydrate gypsum crystals thiab nruab nrab ntawm dihydrate gypsum crystals thiab muab tub lim.Ua ke ua ke los ua gypsum-based self-leveling mortar tsim lub zog, thiab gypsum-based self-leveling mortar tov nrog redispersible latex hmoov, cov hmoov latex tsim ib qho kev sib txuas hauv gypsum-based self-leveling mortar, thiab dihydrate gypsum crystals thiab fillers, crystals Ib tug organic choj yog tsim los ntawm cov siv lead ua thiab dihydrate gypsum siv lead ua, thiab ib tug organic zaj duab xis yog tsim nyob rau hauv lub dihydrate gypsum siv lead ua los qhwv thiab txuas cov sib tshooj ntawm cov dihydrate gypsum muaju, yog li ua kom lub cohesion thiab cohesion. ntawm gypsum-based self-leveling mortar thiab txhim kho Lub zog ntawm gypsum-based self-leveling mortar Lub latex hmoov muaj cov yeeb yaj kiab tsim cov khoom hauv cov mortar, uas tuaj yeem txhim kho kev sib koom ua ke thiab kev sib koom ua ke ntawm cov tshuaj khib nyiab qhuav.Kev tsim kom muaj kev sib raug zoo ntawm cov muab tub lim txhim kho kev sib koom ua ke ntawm cov dihydrate gypsum crystals thiab cov muab tub lim, yog li txhim kho lub zog ntawm gypsum-based self-leveling mortar macroscopically.
