Abubuwan da ke Shafar Samar da Danko na Hydroxypropyl Methylcellulose

Ma'aunin danko nahydroxypropyl methylcellulosema'auni ne mai matuƙar muhimmanci. Danko ba ya wakiltar tsarki. Danko na cellulose HPMC ya dogara ne akan tsarin samarwa. Yanayin amfani daban-daban ya kamata ya zaɓi cellulose HPMC tare da danko daban-daban, ba girman danko na cellulose HPMC ba, mafi kyau! Abin da ke daidai shine daidai √

Kula da Danko

1. Hydroxipropyl methylcellulose mai yawan danko ba zai iya samar da cellulose mai yawan danko ba sai ta hanyar amfani da injin tsotsar ruwa da maye gurbinsa da nitrogen. Gabaɗaya, ba za a iya sarrafa samar da cellulose mai yawan danko a China ba. Duk da haka, idan za a iya sanya na'urar auna iskar oxygen a cikin tukunyar, za a iya sarrafa samar da danko ta hanyar wucin gadi.

Amfani da wakilan haɗin gwiwa

2. Bugu da ƙari, idan aka yi la'akari da saurin maye gurbin nitrogen, kuma a lokaci guda, yana da sauƙi a samar da samfuran da ke da ɗanɗano mai yawa komai yadda tsarin yake rufewa da iska. Tabbas, matakin polymerization na auduga mai tsabta shima yana da mahimmanci. Idan hakan bai yi aiki ba, yi shi ta hanyar haɗin hydrophobic. Akwai wakilan haɗin gwiwa na gida a wannan fanni. Wane irin wakilin haɗin gwiwa aka zaɓa yana da babban tasiri akan aikin samfurin ƙarshe.

Abubuwan da ke cikin Hydroxypropyl

3. Iskar oxygen da ke cikin reactor tana haifar da lalacewar cellulose da rage nauyin kwayoyin halitta, amma iskar oxygen da ke cikinsa tana da iyaka. Ba abu ne mai wahala a sami danko mai yawa ba muddin kwayoyin da suka karye sun sake hadewa. Duk da haka, yawan jikewar ruwa shima yana da alaƙa da abun da ke cikin hydroxypropyl. Wasu masana'antu suna son rage farashi da farashi ne kawai, kuma ba sa son ƙara abun da ke cikin hydroxypropyl, don haka ingancin ba zai iya kaiwa ga matakin irin waɗannan samfuran ƙasashen waje ba.
