Umehluko Phakathi kwe-EHEC ne-HPMC

I-EHEC ne-HPMC yizinhlobo ezimbili ezivame ukusetshenziswa zama-polymer anezakhiwo zamakhemikhali nezakhiwo ezahlukene.I-EHEC imele i-ethyl hydroxyethyl cellulose, kuyilapho i-HPMC imele i-hydroxypropyl methylcellulose.Kulesi sihloko, sizoxoxa ngomehluko phakathi kwe-EHEC ne-HPMC ngokwesakhiwo samakhemikhali, izakhiwo, ukusetshenziswa, nokuphepha.

1. Isakhiwo Samakhemikhali

I-EHEC iyi-polymer encibilika emanzini etholakala ku-cellulose.Kuyi-ether ye-cellulose eguquliwe enakho kokubili amaqembu e-ethyl kanye ne-hydroxyethyl anamathele kumgogodla we-cellulose.I-degree of substitution (DS) ye-EHEC ibhekisela enanini lamaqembu e-ethyl ne-hydroxyethyl akhona ngeyunithi ngayinye ye-anhydroglucose (AGU) yomgogodla we-cellulose.I-DS ye-EHEC ingaba kusuka ku-0.2 kuye ku-2.5, ngamavelu e-DS aphezulu abonisa izinga eliphezulu lokushintsha.

I-HPMC, ngakolunye uhlangothi, iyi-polymer encibilika emanzini etholakala ku-cellulose.I-ether ye-cellulose eguquliwe enawo womabili amaqembu e-hydroxypropyl kanye ne-methyl anamathiselwe kumgogodla we-cellulose.Izinga lokushintshwa kwe-HPMC lisho inombolo yamaqembu e-hydroxypropyl kanye ne-methyl akhona nge-AGU ngayinye yomgogodla we-cellulose.I-DS ye-HPMC ingaba kusuka ku-0.1 kuye ku-3.0, ngamavelu e-DS aphezulu abonisa izinga eliphezulu lokushintsha.

2. Izakhiwo

I-EHEC ne-HPMC banezakhiwo ezahlukene ezibenza bafanelekele izinhlelo zokusebenza ezahlukene.Ezinye zezakhiwo ezibalulekile ze-EHEC ne-HPMC zibalwe ngezansi:

a.Ukunyibilika: I-EHEC ayincibiliki kancane emanzini kune-HPMC, futhi ukuncibilika kwayo kuncipha njengoba izinga lokushintsha likhula.I-HPMC, ngakolunye uhlangothi, incibilika kakhulu emanzini.

b.I-Rheology: I-EHEC iyimpahla ye-pseudoplastic, okusho ukuthi ibonisa ukuziphatha kokugunda kwe-shear.Lokhu kusho ukuthi i-viscosity ye-EHEC iyancipha njengoba izinga lokugunda likhuphuka.I-HPMC, ngakolunye uhlangothi, iyimpahla ye-Newtonian, okusho ukuthi i-viscosity yayo ihlala ingashintshi kungakhathaliseki izinga lokugunda.

c.Izakhiwo zokwenza ifilimu: I-EHEC inezakhiwo ezinhle zokwenza ifilimu, ezenza ifanelekele ukusetshenziswa ekugqokeni namafilimu.I-HPMC futhi inezici zokwenza ifilimu, kodwa amafilimu angase abe mahle futhi athambekele ekuqhekekeni.

d.Ukuzinza: I-EHEC izinzile phezu kohlu olubanzi lwe-pH nezimo zokushisa.I-HPMC futhi izinzile phezu kwebanga le-pH elibanzi, kodwa ukuzinza kwayo kungase kuthinteke amazinga okushisa aphezulu.

3. Isebenzisa

I-EHEC ne-HPMC asetshenziswa ezinhlobonhlobo zezicelo ezimbonini zokudla, ezemithi, nezokunakekelwa komuntu siqu.Okunye ukusetshenziswa okubalulekile kwe-EHEC ne-HPMC kubalwe ngezansi:

a.Imboni yokudla: I-EHEC ivame ukusetshenziswa njenge-thickener, stabilizer, kanye ne-emulsifier emikhiqizweni yokudla efana namasoso, okokugqoka, nezinto ezibhakwayo.I-HPMC iphinde isetshenziswe njenge-thickener kanye ne-stabilizer emikhiqizweni yokudla, kodwa isetshenziswa kakhulu njenge-ejenti yokugcoba emikhiqizweni ye-confectionery efana ne-gummy candies kanye noshokoledi.

b.Imboni yezemithi: I-EHEC isetshenziswa njenge-binder, disintegrant, kanye ne-ejenti yokugqoka ithebhulethi ekwenziweni kwemithi.I-HPMC iphinde isetshenziswe njengesihlanganisi, isihlukanisi, kanye ne-ejenti yokuhlanganisa amathebulethi ekwenziweni kwemithi, kodwa isetshenziswa kakhulu njengesisebenzeli esikhishwa njalo.

4. Ukuphepha

I-EHEC ne-HPMC ngokuvamile zibhekwa njengeziphephile ukusetshenziswa ekudleni nasezinhlelweni zemithi.Kodwa-ke, njenganoma iyiphi into yamakhemikhali, kungase kube nezingozi ezithile ezihlobene nokusetshenziswa kwazo.
