Yuav ua li cas rau siab ntshiab HPMC thiab tsis yog HPMC.
1. Cov kua dej ntshiab hydroxypropyl methyl cellulose tau hais txog kev hloov siab thiab muaj peev xwm tuav dej> 95%; Kev tshuaj dej HPMC kua dej yog ntau tshaj 80%.
2. Nws yuav ua fibrous nyob rau hauv lub tshuab tsom iav lossis loj rau HPMC hmoov ntshiab, thiab granular lossis crystal yuav pom nyob rau hauv tsom iav los yog loj dua rau cov HPMC uas tsis yog huv.
3. Cov hydroxypropyl methyl cellulose yuav siv tib tus nqi ntawm 2 kuaj hauv daim iav. Tom qab ntawd taws nws nrog hluav taws thiab tos kom rov tua kom kawg, saib cov tshauv tshuav ntawm daim iav. Lub chassis yog ib lub tiaj tus taws ntshiab hydroxypropyl methyl cellulose. Lub npe hu ua hydroxypropyl methyl cellulose base tau nce. Lub smoldering chassis yog tiaj tus, qhia zoo cellulose
