Ntxiv HydroxyPropyyl nrho Metylencellulose los ua kom muaj hmoov putty, nws loj heev yuav ua rau tsis muaj zog heev, yog li ntau npaum li cas rau kev ua haujlwm hydroxyylropen rau putty hmoov xav tau? Cia peb txheeb xyuas nws rau txhua tus.
Nws yog qhov zoo dua ntxiv hydroxypropy kasthylculose mus rau lub putterty nrog lub viscosity ntawm cov hmoov uas muaj putty, thiab nws cov dej khaws cia kuj tseem zoo heev. Yog tias nws siv rau kev tshuaj khib, nws xav tau me ntsis viscosity, xws li 150,000 lossis 200,000 viscosity. Feem ntau, hydroxypropyl methylcellose muaj cov dej rov qab zoo dua nrog cov viscosity ntau dua.
Dab tsi yog kev siv ntawm kev ntxiv hydroxypropyl methylculose mus rau putty hmoov? Lub luag haujlwm tseem ceeb yog dab tsi?
HPMC yog siv rau hauv cov hmoov putty los thicken, khaws dej thiab txhim kho kev tsim kho.
Thickening: cellulose tuaj yeem ua tuab rau ncua thiab ua kom cov tshuaj daws teeb meem nce thiab nqis, thiab tiv taus sagging.
Dej khaws cia: Ua cov hmoov ua kom qhuav maj mam, thiab pab cov ntug dej tshauv kom muaj kev cuam tshuam hauv kev ua dej. Kev tsim kho: Cellulose muaj cov nyhuv muaj lubricating nyhuv, uas tuaj yeem ua rau cov hmoov puty muaj kev tsim kho zoo.
HydroxyPropyyl methylculose tsis koom nrog kev tshuaj lom neeg hauv Putty, nws tsuas yog ua lub luag haujlwm ntawm lub luag haujlwm, thiab nws tsis muaj kob thiab tsis muaj tshuaj lom. Nws yog qhov feem ntau siv additive hauv cov vaj tse niaj hnub thiab yog dav siv nyob rau hauv puelty cug
