RDP rau tus kheej-leveling compound

RedispersiblePolymer hmoov RDP/VAEyog tuab txheej ntawm plaster puag nws tus kheej-leveling mortar kev ua tau zoo yog ib qho tseem ceeb additive, los ntawm kev xeemRedispersible Polymer hmoov RDP/VAENyob rau tuab txheej ntawm lub zog ntawm lub cev thiab txhua yam khoom ntawm gypsum puag nws tus kheej-leveling mortar, thiab los ntawm kev tsom xam microscopic qhia.Redispersible Polymer hmoov RDP/VAEtxhawm rau txhim kho cov khoom siv ntawm gypsum puag tus kheej-leveling mortar nkaus xwb, piav qhia RedispersiblePolymer hmoov RDP/VAEnyob rau hauv lub luag hauj lwm ntawm gypsum raws li tus kheej-leveling loj.

RedispersiblePolymer hmoov RDP/VAEyog ib tug dav siv organic binder uas tuaj yeem txhim kho cov khoom ntawm gypsum raws li cov khoom siv hauv tsev. Cov txiaj ntsig ntawm kev sim qhia tau hais tias qhov pib fluidity ntawm tus kheej-leveling mortar ntawm tuab gypsum puag nce ua ntej thiab tom qab ntawd txo qis nrog qhov nce ntawm qhov sib tov ntawm cov kua nplaum hmoov. Yog vim li cas yog cov kua nplaum hmoov muaj qee yam viscosity hauv cov dej yaj. Thaum cov khoom sib tov qis, qhov nce ntawm cov viscosity ntawm slurry txhim kho lub peev xwm raug ncua ntawm slurry rau muab tub lim, uas yog qhov zoo rau cov dej ntws ntawm slurry. Thaum cov ntsiab lus ntawm cov hmoov roj hmab tseem nce ntxiv, qhov nce ntawm slurry viscosity ua rau qhov nce ntawm slurry viscosity thiab txo qhov fluidity. Cov kua nplaum hmoov muaj me ntsis cuam tshuam rau 20min fluidity ntawm mortar.

RedispersiblePolymer hmoov RDP/VAERaws li ib yam ntawm cov organic binder, qhov kev siv ntawm txoj kev loj hlob nyob ntawm slurry dej evaporation, daim ntawv cog lus lub zog, zaj duab xis tsim qhov cub qhuav tej yam kev mob ntawm noo noo evaporation, gypsum raws li tus kheej-leveling mortar hmoov tuaj yeem tsim cov zaj duab xis txuas ntxiv, muaj kev cog lus zoo thiab qhov cub qhuav lub zog. ntawm gypsum raws li tus kheej-leveling mortar nrog hmoov cov ntsiab lus nce.

Tsis ntxivRedispersible Polymer hmoov RDP/VAEMuaj ntau cov gypsum raws li tus kheej-leveling mortar bar, columnar dihydrate gypsum crystals thiab irregular packing Nruab nrab ntawm dihydrate gypsum crystals thiab dihydrate gypsum crystals thiab crisscross sib tshooj ntawm packing ua ke, los ntawm qhov tsis sib xws nruj nreem ntim ua ke ua gypsum raws li tus kheej-leveling mortar,Redispersible Polymer hmoov RDP/VAEgypsum raws li tus kheej-leveling mortar,Redispersible Polymer hmoov RDP/VAENyob rau ntawm qhov tsim ntawm gypsum raws li tus kheej-leveling mortar filamentous kev twb kev txuas, lub dihydrate gypsum muaju thiab packing, organic choj tsim ntawm muaju thiab siv lead ua, organic zaj duab xis yog tsim nyob rau hauv lub dihydrate gypsum crystals, lub overlapping qhov chaw ntawm dihydrate gypsum crystals pob thiab kev twb kev txuas, Ua kom cov cohesion ntawm gypsum raws li tus kheej-leveling mortar thiab cohesive quab yuam, Txhim kho lub zog ntawm gypsum raws li tus kheej-leveling mortarRedispersible Polymer hmoov RDP/VAENyob rau hauv ib lub mortar nrog ib tug membranous, tuaj yeem txhim kho cov cohesion ntawm qhuav mortar thiab daim ntawv cog lus lub zog, hmoov ntawm dihydrate gypsum crystals thiab packing zaj duab xis tsim teeb meem ntawm dihydrate gypsum crystals thiab zoo daim ntawv cog lus yog tsim ntawm muab tub lim thiab txhim kho lub cohesion ntawm dihydrate gypsum muaju thiab packing. Yog li, daim ntawv cog lus lub zog ntawm gypsum puag nws tus kheej-leveling mortar yog txhim kho macroscopically.
