Ntxiv hydroxypropyl methylcellulose los ua cov hmoov putty, nws cov viscosity tsis yooj yim kom loj dhau, loj dhau yuav ua rau tsis zoo, yog li cov viscosity ntau npaum li cas hydroxypropyl methylcellulose rau putty hmoov xav tau?
Nws yog qhov zoo tshaj rau ntxiv hydroxypropyl methylcellulose rau cov hmoov putty nrog viscosity ntawm 10 lossis 75,000, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov hmoov putty, thiab nws cov dej tuav kuj zoo heev.Yog tias nws yog siv rau mortar, nws xav tau viscosity siab dua me ntsis, xws li 150,000 lossis 200,000 viscosity.Feem ntau, hydroxypropyl methylcellulose muaj cov dej tuav zoo dua nrog cov viscosity ntau dua.
Dab tsi yog kev siv ntxiv hydroxypropyl methylcellulose rau putty hmoov?Lub luag haujlwm tseem ceeb yog dab tsi?
HPMC yog siv rau hauv cov hmoov putty kom thicken, khaws dej thiab txhim kho kev tsim kho.Thickening: cellulose tuaj yeem thicken kom tshem tawm, ua kom cov tshuaj sib xws thiab zoo ib yam, thiab tiv thaiv sagging.Kev tuav dej: ua kom cov hmoov putty qhuav maj mam, thiab pab cov hmoov tshauv calcium kom hnov ​​​​mob hauv qab dej.Kev tsim kho: Cellulose muaj cov nyhuv lubricating, uas tuaj yeem ua rau cov hmoov putty muaj kev tsim kho zoo.
Hydroxypropyl methylcellulose tsis koom nrog cov tshuaj tiv thaiv hauv putty, nws tsuas yog ua lub luag haujlwm pabcuam, thiab nws tsis muaj xim thiab tsis muaj tshuaj lom.Nws yog feem ntau siv additive nyob rau hauv niaj hnub vaj tse thiab yog dav siv nyob rau hauv putty mortar
