Tusmada viscosity eehydroxypropyl methylcellulosewaa tilmaame aad muhiim u ah.Viscosity ma matalo daahirnimada.Viscosity of cellulose HPMC waxay ku xiran tahay habka wax soo saarka.Deegaannada kala duwan ee loo isticmaalo waa inay doortaan HPMC cellulose leh muuqaalo kala duwan, ma aha heerka sare ee viscosity of cellulose HPMC, ayaa ka wanaagsan!Waxa saxda ah waa sax √
Xakamaynta viscosity
1.Hydroxypropyl methylcellulose-viscosity High-viscosity ma soo saari karo cellulose aad u sarreeya oo keliya in la faaruqiyo oo lagu beddelo nitrogen.Guud ahaan, wax-soo-saarka cellulose-ka-jilicsan ee Shiinaha lama xakamayn karo.Si kastaba ha ahaatee, haddii qalabka cabbiraadda ogsijiinta lagu rakibi karo kiliyaha, wax-soo-saarka viscosity-ga waxaa lagu xakameyn karaa si macmal ah.
Isticmaalka wakiilada associative
2. Intaa waxaa dheer, iyada oo la tixgelinayo xawaaraha beddelka ee nitrogen, isla mar ahaantaana, aad bay u fududahay in la soo saaro alaabooyin badan oo viscosity ah iyada oo aan loo eegin sida hawo-mareenka nidaamka.Dabcan, heerka polymerization ee suufka la safeeyey ayaa sidoo kale muhiim ah.Haddii taasi shaqayn waydo, ku samee ururka hydrophobic.Waxa jira wakiilo wada shaqayneed oo gudaha ah oo arrintan khuseeya.Nooca wakiilka associative ee la doortay ayaa saameyn weyn ku leh waxqabadka badeecada ugu dambeysa.
Waxyaabaha ay ka kooban tahay Hydroxypropyl
3. Ogsajiinta hadhaaga ah ee ku jirta reactor waxay keentaa hoos u dhaca cellulose iyo dhimista miisaanka kelli, laakiin ogsijiinta hadhaaga ah ayaa xaddidan.Ma adka in la sameeyo viscosity sare ilaa inta unugyadii jabay dib la isugu xirayo.Si kastaba ha ahaatee, heerka dherga biyaha ayaa sidoo kale si dhow ula xiriira waxa ku jira hydroxypropyl.Warshadaha qaarkood waxay rabaan oo kaliya inay yareeyaan qiimaha iyo qiimaha, mana rabaan inay kordhiyaan nuxurka hydroxypropyl, markaa tayada ma gaari karto heerka badeecadaha shisheeye ee la midka ah.
arrimo kale
4. Heerka haynta biyaha ee badeecadu waxay leedahay xidhiidh weyn oo la leh hydroxypropyl, laakiin dhammaan habka falcelinta, waxay sidoo kale go'aamisaa heerka haynta biyaha, saameynta alkalization, saamiga methyl chloride iyo propylene oxide, iyo xoojinta alkali .Iyo saamiga biyaha ee suufka la safeeyey ayaa go'aaminaya waxqabadka alaabta.
