4 Basic Production Technologies da Formulas na HPMC, Kar a ɓace!

Hydroxypropyl methylcellulose (HPMC) wani nau'in polymer ne wanda aka yi amfani da shi sosai a masana'antu daban-daban, ciki har da gine-gine, magunguna, da masana'antun abinci.Ana samar da HPMC ta amfani da fasahohin samarwa daban-daban da ƙira, dangane da aikace-aikacen da aka yi niyya.A cikin wannan labarin, za mu bincika ainihin fasahar samarwa guda huɗu da dabaru na HPMC waɗanda bai kamata ku rasa ba.

1. Fasahar Etherification Fasahar etherification ita ce fasahar samarwa da aka fi amfani da ita don HPMC.A cikin wannan tsari, ana bi da cellulose tare da alkali, kamar sodium hydroxide, don samar da alkali cellulose.Ana mayar da sinadarin cellulose na alkali tare da propylene oxide da methyl chloride don samar da HPMC.Ana iya sarrafa matakin maye gurbin (DS) na HPMC ta hanyar daidaita ma'auni na propylene oxide zuwa methyl chloride yayin amsawa.

Dabarar don HPMC da aka samar ta amfani da fasahar etherification ita ce:

Cellulose + Alkali → Alkali Cellulose Alkali Cellulose + Propylene Oxide + Methyl Chloride → HPMC

2. Fasahar bushewa Fesa Fasahar bushewar feshi ita ce fasahar samar da ci gaba ga HPMC.A cikin wannan tsari, ana narkar da cellulose a cikin maganin alkali sannan a mayar da martani da propylene oxide da methyl chloride.Sakamakon maganin HPMC sai a fesa bushewa don samar da foda na HPMC.

Dalili na HPMC da aka samar ta amfani da fasahar bushewar feshi shine:

Cellulose + Alkali → Alkali Cellulose Alkali Cellulose + Propylene Oxide + Methyl Chloride → Maganin HPMC Maganin HPMC + Fasa bushewa → HPMC Foda

3. Fasaha Polymerization Dakatarwa Fasahar polymerization na dakatarwa wata fasahar samarwa ce ta HPMC.A cikin wannan tsari, ana dakatar da cellulose a cikin wani ƙarfi sannan a amsa tare da propylene oxide da methyl chloride a gaban mai ƙaddamar da polymerization don samar da HPMC.

Dalili na HPMC da aka samar ta amfani da fasahar polymerization na dakatarwa shine:

Cellulose + Solvent + Polymerization Initiator → Cellulose Suspension Cellulose Suspension + Propylene Oxide + Methyl Chloride → HPMC

4. Fasaha Polymerization Magani Fasahar polymerization mafita sabuwar fasahar samarwa ce don HPMC.A cikin wannan tsari, cellulose yana narkar da shi a cikin wani ƙarfi sannan ya amsa tare da propylene oxide da methyl chloride a gaban mai ƙaddamar da polymerization don samar da HPMC.

Dabarar don HPMC da aka samar ta amfani da fasahar polymerization na bayani shine:

Cellulose + Solvent + Polymerization Initiator → Cellulose Magani Cellulose Magani + Propylene Oxide + Methyl Chloride → HPMC

A ƙarshe, HPMC wani nau'in polymer ne wanda aka samar da shi ta amfani da fasahohin samarwa da ƙira iri-iri, dangane da aikace-aikacen da aka yi niyya.Hanyoyin fasaha na samarwa guda huɗu da dabarun HPMC sun haɗa da fasahar etherification, fasahar bushewa ta feshi, fasahar polymerization na dakatarwa, da fasahar polymerization.Fahimtar fasahar samarwa da dabara na HPMC na iya taimaka wa masana'antun su zaɓi samfurin HPMC daidai don takamaiman aikace-aikacen su.
