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 axhunywe 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, i-disintegrant, kanye ne-ejenti yokugqoka ithebhulethi ekwenziweni kwemithi. I-HPMC iphinde isetshenziswe njengesihlanganisi, isihlukanisi, kanye ne-ejenti yokuhlanganisa amathebulethi ekwenziweni kwemithi, kodwa isetshenziswa kakhulu njenge-ejenti ekhishwa isikhathi eside.

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.
