We know that hydroxypropyl methylcellulose is a powdery substance at room temperature, and the powder is relatively uniform, but when you put it in water, the water will become viscous at this time, And with a certain degree of viscosity, we can correctly identify it by using the characteristics of hydroxypropyl methylcellulose, and general construction sites will generally adapt to such a characteristic of it, let the rest of the putty powder combine to increase The Txoj kev nplaum ntawm cov hmoov txhuas thiab cov phab ntsa saum npoo av, yog li cov ntsiab lus yuav tsum tau them nyiaj rau thaum ntxiv hydroxypropylulose mus rau cov hmoov putty?
Thaum ib qho hmoov dab tsi yog ua kom muaj kev daws teeb meem, yuav tsum muaj qee qhov kev xav tau, thiab kev siv ntawm hydroxypropylulose tsis muaj kev zam. Thaum ua cov tshuaj sib xyaw nrog cov hmoov ua kom muaj putty, nws cov tshuaj feem ntau nyob ntawm qhov kub thiab txias, ib puag ncig, qhov zoo ntawm cov ntug dej tshauv muaj feem cuam tshuam nrog cov xwm txheej. Feem ntau, lwm cov kua nplaum hmoov uas yuav tsum tau npaj. Feem ntau, cov neeg yuav siv hydroxypropylulose nruab nrab ntawm 4 kg thiab 5 kg, tab sis feem ntau cov nyiaj siv nyob rau lub caij ntuj no siab dua uas nyob rau lub caij ntuj sov. Nws yuav tsum tsawg dua. Thaum koj ua cov tshuaj sib tov, koj tuaj yeem suav nws kom zoo zoo.
Ntxiv mus, thaum cov sib tov tov yog npaj rau ntau thaj tsam, cov tshuaj no kuj txawv. Piv txwv li, txhawm rau npaj cov kev daws teeb meem hauv qee thaj av ntawm Beijing, nws yog feem ntau tsim nyog los ntxiv 5 kg ntawm HPMC. Tab sis tus nqi no tseem yog rau lub caij ntuj sov, thiab 0.5 kg tsawg dua lub caij ntuj no; but in areas like Yunnan, when making the solution, generally only need to put 3 kg – 4 kg of HPMC, the dosage It is much less than Beijing, and the environment is different, and there will be differences in the natural amount.
