Nyob rau hauv cov hmoov putty, nws plays peb lub luag hauj lwm ntawm thickening, dej tuav thiab kev tsim kho.
Thickening: Cellulose tuaj yeem ua kom tuab kom tshem tawm thiab ua kom cov tshuaj sib txawv nce thiab nqis, thiab tiv thaiv sagging.
Kev tuav dej: Ua kom cov hmoov putty qhuav maj mam los 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.
Kev nyab xeeb ntau lawm tseem ceeb dua Mount Tai
HPMC tsis koom nrog cov tshuaj tiv thaiv, tab sis tsuas yog ua lub luag haujlwm pabcuam. Ntxiv dej rau cov hmoov putty thiab muab tso rau ntawm phab ntsa yog cov tshuaj tiv thaiv, vim hais tias cov tshuaj tshiab yog tsim. Muab cov hmoov putty rau ntawm phab ntsa ntawm phab ntsa, zom nws ua hmoov, thiab siv dua. Nws yuav tsis ua haujlwm vim tias cov tshuaj tshiab (calcium carbonate) tau tsim. Yog lawm. Cov ntsiab lus tseem ceeb ntawm cov hmoov tshauv calcium hmoov yog: sib tov ntawm Ca (OH2, CaO thiab ib qho me me ntawm CaCO3, CaO + H2O = Ca(OH2-Ca(OH2 + CO2 = = CaCO3↓ + H2O) Cov nyhuv ntawm tshauv calcium ntawm CO2. Hauv dej thiab huab cua Nyob rau hauv cov xwm txheej no, calcium carbonate yog tsim, thaum HPMC tsuas yog khaws cov dej thiab pab cov tshuaj tiv thaiv zoo ntawm cov hmoov tshauv calcium, thiab tsis koom nrog cov tshuaj tiv thaiv nws tus kheej.
Cov hmoov poob ntawm putty hmoov yog feem ntau muaj feem xyuam rau qhov zoo ntawm cov hmoov tshauv calcium, thiab muaj me ntsis ua rau HPMC. Cov ntsiab lus calcium uas tsis tshua muaj ntawm cov calcium grey thiab qhov tsis zoo ntawm CaO thiab Ca (OH2 hauv cov calcium grey yuav ua rau cov hmoov poob.
