viscosity ntawm cellulose ether HPMC rau tus kheej-leveling mortar

Lub viscosity ntawm Hydroxypropyl Methylcellulose (HPMC) siv nyob rau hauv tus kheej-leveling mortar formulations yog ib qho tseem ceeb parameter uas cuam tshuam tus cwj pwm khiav, workability, thiab kev ua tau zoo ntawm lub mortar. Self-leveling mortars yog tsim los kom ntws tau yooj yim thiab theem lawv tus kheej yam tsis muaj troweling, ua viscosity tswj qhov tseem ceeb rau kev ua tiav cov khoom xav tau. Nov yog cov lus qhia dav dav rau xaiv qhov viscosity ntawm HPMC rau tus kheej-leveling mortar:

1. Qib viscosity qis: tus kheej-leveling mortars feem ntau xav tau HPMC nrog qis viscosity 400 CPS qib. Cov qib no ntawm HPMC muab qhov tsim nyog txaus txaus thiab cov yam ntxwv theem rau lub mortar thaum tseem tswj kev sib raug zoo thiab kev ruaj ntseg.
2. Tshwj xeeb Viscosity Range: Qhov tshwj xeeb viscosity ntau yam ntawm HPMC siv nyob rau hauv tus kheej-leveling mortar formulations yuav txawv nyob ntawm seb yam xws li qhov xav tau flowability, thickness ntawm daim ntawv thov, ambient kub, thiab curing lub sij hawm. Txawm li cas los xij, qib viscosity nyob rau hauv thaj tsam ntawm 400 mPa·s feem ntau yog siv rau tus kheej-leveling mortars.
3. Kev Ua Haujlwm thiab Kev Tswj Flow: Lub viscosity ntawm HPMC yuav tsum tau hloov kho kom ua tiav qhov xav tau ua haujlwm thiab khiav tswj ntawm tus kheej-leveling mortar. Cov qib viscosity qis dua muab cov dej ntws ntau dua thiab sib kis tau yooj yim dua, thaum cov qib viscosity siab dua muab kev tswj xyuas zoo dua ntawm cov dej ntws thiab qib theem.
4. Compatibility nrog Lwm yam Additives: HPMC siv nyob rau hauv tus kheej-leveling mortar formulations yuav tsum tau sib xws nrog lwm yam additives xws li superplasticizers, cua entrainers, thiab defoamers. Lub viscosity ntawm HPMC yuav tsum raug xaiv los xyuas kom meej kev sib raug zoo nrog cov additives thiab tswj cov khoom uas xav tau ntawm lub mortar.
5. Kev Tswjhwm Zoo thiab Kev Ntsuas: Nws yog ib qho tseem ceeb uas yuav tsum tau ua kom muaj kev tswj xyuas kom zoo los txiav txim siab qhov zoo tshaj plaws viscosity ntawm HPMC rau ib qho tshwj xeeb ntawm tus kheej-leveling mortar formulation. Kev ntsuam xyuas yuav suav nrog kev ntsuas rheological, ntsuas ntws, thiab kev ntsuas kev ua haujlwm raws li kev simulated daim ntawv thov.
6. Cov lus pom zoo ntawm cov chaw tsim khoom: Cov neeg tsim khoom ntawm HPMC feem ntau muab cov ntaub ntawv qhia txog kev siv tshuab thiab cov txheej txheem qhia cov qib viscosity pom zoo rau cov ntawv siv sib txawv, suav nrog tus kheej qib mortars. Nws raug nquahu kom sab laj cov lus pom zoo no thiab ua haujlwm nrog HPMC tus neeg xa khoom los xaiv cov qib viscosity uas haum tshaj plaws rau koj daim ntawv thov tshwj xeeb.

Nyob rau hauv cov ntsiab lus, lub viscosity ntawm HPMC rau tus kheej-leveling mortar yuav tsum tau ua tib zoo xaiv raws li qhov xav tau flowability, workability, thiab kev ua tau zoo ntawm cov mortar, coj mus rau hauv tus account yam xws li daim ntawv thov thickness, ambient tej yam kev mob, compatibility nrog lwm yam additives, thiab chaw tsim tshuaj paus. cov lus pom zoo.
