1. Cov kws kho mob cellulos (MC, HPMC, HEC)
MC, HPMC, thiab HEC muaj feem ntau siv hauv kev tsim kho putty, pleev xim, cug thiab lwm yam khoom, feem ntau rau dej ceev thiab lubrication. Nws yog qhov zoo.
Kev tshuaj xyuas thiab tus qauv qhia:
Hnov 3 gram lossis HPMC lossis HEC, muab tso rau hauv kev daws teeb meem, thiab muab tso rau hauv cov pa dej, thiab muab tso rau hauv cov kev hloov pauv ntawm cov kua nplaum hauv ib puag ncig ntawm -38 ° C. Yog hais tias cov tshuaj aqueous yog qhov tseeb thiab pob tshab thiab cov viscosity siab thiab zoo fluidity, nws txhais tau tias cov khoom muaj qhov pib zoo. Txuas ntxiv saib xyuas ntau dua 12 lub hlis, thiab nws tseem pheej hloov pauv, qhia tias cov khoom muaj kev nyab xeeb zoo thiab muaj peev xwm siv tau nrog kev ntseeg siab; Yog hais tias cov kua aqueous tau pom tias maj mam hloov pauv xim, ua lub raj mis, muaj cov tshuaj tsw qab, muaj cov tshuaj tsw qab, ua kom cov khoom lag luam raj ntses tsis zoo tias cov khoom lag luam zoo tsis zoo. Yog tias nws yog siv nyob rau hauv kev tsim cov khoom lag luam, nws yuav ua rau cov khoom tsis khov tseem ceeb.
2. CMCI, CMCS
Lub visci thiab CMCI thiab CMCS yog nruab nrab ntawm 4 thiab 8000, thiab lawv feem ntau yog siv nyob rau hauv phab ntsa leveling thiab plastering cov ntaub ntawv sab hauv Putty thiab lub zog ua kom huv thiab lubrication.
Kev tshuaj xyuas thiab tus qauv qhia:
Hnyav 3 gram ntawm cmci lossis CMCs, muab tso rau hauv 300 ml ntawm kev daws teeb meem, yog tias cov khoom siv roj a hnov zoo thaum pib, yog tias cov tshuaj aqueous, yog tias cov tshuaj aqueous yog turbid thiab tau tshem tawm, nws txhais tau tias cov khoom muaj ore hmoov, thiab cov khoom yog kev deev. Cov. Txuas ntxiv saib xyuas ntau dua 6 lub hlis, thiab nws tseem tuaj yeem tsis hloov pauv, qhia tias cov khoom muaj kev nyab xeeb zoo thiab muaj peev xwm siv tau nrog kev ntseeg siab; Yog tias nws tsis tuaj yeem tswj hwm, nws pom tias cov xim yuav hloov, kev daws teeb meem, yuav tsum muaj huab, yog siv hauv cov khoom lag luam, yog tias siv cov teeb meem khoom muaj teeb meem zoo
