Uyini umehluko phakathi kwe-HPMC ngaphandle kwe-S?

IHydroxypropyl Methylcellulose (HPMC) yinto yamakhemikhali esetshenziswa kabanzi kwizimboni zezemithi, zokudla, zokugcoba kanye nokwakha. Kwenziwa ikakhulukazi nge-methylcellose kanye ne-hydroxypropyl celtulose ngokusebenzisa ukusabela kwamakhemikhali, futhi inemisebenzi yokuqina, ukuqina, ukwakheka kwamafilimu nokuthambisa.

Izici eziyisisekelo ze-HPMC
Isakhiwo samakhemikhali: Ukwakheka kwamakhemikhali kwe-HPMC kuqukethe ukufakwa esikhundleni okubili, i-methyl ne-hydroxyproppyl, exhunywe kwi-molecule ye-cellulose ngokuphendula kwetherali. Ukuba khona kwamaqembu we-methylyproppy kwenza kube ne-solubility enhle yamanzi kanye nomsebenzi ongaphezulu.

I-Solubinity: I-HPMC ingancibilikisa ngokushesha emanzini abandayo ukwakha isixazululo esibonakalayo noma esincanyana esincane, kepha kuyawungasebenzi emanzini ashisayo. Le mpahla ikwenza kube yinzuzo kwizicelo eziningi, njenge-ejenti yokukhishwa okuqhubekayo kanye nokukhululwa emakheni amakhambi.

I-Viscosity: I-viscosity yesisombululo se-HPMC ithintekile yokushisa, ukugxila kanye nezinga lokufaka esikhundleni. Imikhiqizo ye-HPMC enamadigri ahlukene wokufaka esikhundleni anganikeza ama-visosities ahlukene emazingeni okushisa ahlukahlukene ukuze ahlangabezane nezidingo zohlelo lokusebenza ezahlukene.

Umehluko phakathi kwe-HPMC yamahhala ye-S-HPMC ne-HPMC ejwayelekile
Kwezinye izinhlelo zokusebenza, ikakhulukazi kwizimboni zezemithi nezokudla, ubumsulwa kanye nokuqukethwe kokungcola komkhiqizo kuyizinkomba ezibucayi kakhulu. Ama-sulphur (s) angabhekwa njengokungcola kwezinye izimo, ngakho-ke ezinye zezimo zohlelo lokusebenza zidinga ukusetshenziswa kwe-S-Free HPMC.

Ukuhlanzeka okuphezulu: I-HPMC yamahhala ye-S-Free ithola igxathu elinzima lokuhlanza ngesikhathi sokukhiqiza ukuze ususe isibabule kanye namakhompiyutha alo. Le HPMC ehlanza kakhulu ilungele izinhlelo zokusebenza ezizwela ukungcola, njengamalungiselelo athuthukile emithi kanye nezimonyo eziphakeme.

Ukuqina okunamandla I-S-Free HPMC ingagcina ukuqina kwezici zayo zomzimba nezamakhemikhali ngaphansi kohlu olubanzi lwezimo zezemvelo futhi lende impilo eshalofini yomkhiqizo.

Ukuphepha okuphezulu: Embonini yezimboni zokudla kanye nezemithi, isibabule kanye namakhompiyutha alo kungadala ukungezwani komzimba noma okunye okusabela kwabanye abantu. Ngakho-ke, i-HPMC yamahhala ye-S-Free ibhekwa iphephe kule mikhakha futhi ilungele uhla olubanzi lwamaqembu abathengi.

Ukunwetshwa kwezindawo zesicelo: Ngenxa yokuhlanzeka kwayo okuphezulu nokuphepha, i-S-free HPMC ingasetshenziswa hhayi kuphela izinhlelo zokusebenza ezijwayelekile zokuqina kanye nokuqina, kepha futhi nezicelo ezikhethekile ezidinga izidakamizwa eziphakeme, izimonyo ezinhle, kanye nezithasiselo ezithile zokudla.

Umehluko ezinhlelweni zokukhiqiza
Ukukhiqizwa kwe-S-Free HPMC kuvame ukubandakanya lezi zinyathelo ezilandelayo:

Ukukhethwa kwezinto ezibonakalayo

Inqubo yokucwilisa: Ngesikhathi sokuphendula okuthe xaxa, ama-catalysts ama-sulfur-free kanye nezithasiselo asetshenziselwa ukugwema ukwethulwa kwesibabule.

Ukwelashwa kwePost: Ngesikhathi sokugeza nokusoma inqubo yomkhiqizo, imithombo yamanzi emsulwa kanye nemishini yamahhala ye-sulfur isetshenziselwa ukunciphisa ukunciphisa okuqukethwe se-sulfur kumkhiqizo.

I-S-Free Hydroxypropyll methylcellulose (HPMC) ifana ne-HPMC ejwayelekile kwizakhiwo eziyisisekelo ezifana nesakhiwo samakhemikhali, i-solubility kanye nokuvikeleka kwayo okuphezulu, zinezinzuzo ezingcono, zinezinzuzo ezingcono, zinezinzuzo ezibalulekile kwezinye izinkambu zesicelo. Ngezinqubo zokukhiqiza eziqinile nokulawulwa kwekhwalithi, i-S-Free HPMC ihlinzeka ngokukhetha okuthembekile kwezicelo ezidinga ubumsulwa obuphezulu nokungcola okuphansi.
