Abubuwan da ke Shafar Samar da Danko na HPMC

1. Kula da Danko

Babban ɗankohydroxypropyl methylcelluloseBa zai iya samar da cellulose mai yawa ba sai ta hanyar amfani da injin tsotsar ruwa da maye gurbinsa da nitrogen. 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.

2. Amfani da wakilan haɗin gwiwa

Bugu da ƙari, idan aka yi la'akari da saurin maye gurbin nitrogen, kuma a lokaci guda, matsewar iskar tsarin yana da kyau sosai, kuma yana da sauƙin samar da samfuran da ke da ɗanɗano mai yawa. Tabbas matakin polymerization na auduga mai kyau shima yana da mahimmanci. Idan har yanzu bai yi aiki ba, ana amfani da hanyar haɗin hydrophobic, kuma wane irin wakili aka zaɓa yana da babban tasiri akan aikin samfurin ƙarshe.

3. Abubuwan da ke cikin Hydroxypropyl

Iskar oxygen da ke cikin kettle na amsawa yana sa cellulose ta lalace kuma nauyin kwayoyin halitta ya ragu, amma iskar oxygen da ta rage tana da iyaka. Muddin an sake haɗa ƙwayoyin da suka karye, ba abu ne mai wahala ba a sami ɗanko mai yawa. Duk da haka, ƙimar jikewar ruwa tana 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 samfuran iri ɗaya ba.

4. Wasu dalilai

Yawan riƙe ruwa na samfurin yana da kyakkyawar alaƙa da hydroxypropyl, amma ga dukkan tsarin amsawar, yana kuma ƙayyade yawan riƙe ruwa, tasirin alkali, rabon methyl chloride da propylene oxide, yawan alkali da ruwa. Rabon da aka yi da auduga mai tsafta yana ƙayyade aikin samfurin.
