Kuti enzanise CMC (CarboxyMethylcellose) uye Hpmc (HPMC (HYDROPPROPYLMETHELCELELELELELELELELELELELELELELES, ZVINOKOSHA, ZVINOGONESESA, ZVINHU ZVINOGONESA, uye ZVINOGONESA ZVINOGONESA. Vese vose cellulose detivatives vanoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, kusanganisira mishonga yemishonga, chikafu, cosmetics uye kuvaka. Imwe neimwe ine yakasarudzika zvivakwa zvinovaita kuti vakwanise kuve vakaringana. Ngatiitei zvakadzama zvakanyanyisa kuenzanisa kuti tione kuti ndeipi iri nani mumamiriro ezvinhu akasiyana.
1. Tsanangudzo uye chimiro:
CMC (CarboxyMethylcellose): CMC ndeyemvura-soluble cellulose inobva yakagadzirwa yakagadzirwa nekuita cellulose uye chloroacetic acid. Iyo ine carboxymethyl mapoka (-ch2-cooh) yakasungwa kune mamwe mapoka ehydroxyl eglucopyranose monomers anogadzira cellulose backbone.
HPMC (HYDROXYPROPYL MetHylcellose): HPMC iri zvakare sollulose cellulose inogadzirwa nekubata cellulose ine procyl chloride. Iyo ine hydroxypruppropyl uye nzira mapoka akasungirirwa kune cellulose backbone.
2. Solubility:
CMC: Nyorovesa mumvura, inogadzira mhinduro yakajeka, viscous. Inoratidza pseudoplastic maitiro maitiro, zvinoreva kuti viscoity yayo inoderera pasi pekushushikana.
HPMC: zvakare zvinyoro-nyoro mumvura, kugadzira zvishoma viscous mhinduro kupfuura CMC. Izvo zvinoratidzirawo maitiro epseudoplastic maitiro.
3.Rhelogical Properties:
CMC: Inoratidza Shear Tete Matanho, zvinoreva kuti viscoity yayo inoderera nekuwedzera shear rate. Ichi chivakwa chinoita kuti zviite kuti zviite zvekushandisa apo kurongedza kunodiwa asi mhinduro inoda kuyerera zviri nyore pasi pehembe, yakadai sekupenda uye mishonga nemishonga.
HPMC: Inoratidza maitiro akafanana neCMC, asi zvavakatengwa kazhinji kazhinji zvakakwirira pakukona kwakaderera. Iyo ine zvivakwa zviri nani firimu-kuita kuti zviite kuti zviite zvekushandisa senge zvipfeko, zvinonamatira uye zvinodzorwa-zvinodzorwa-zvinodzora mishonga maficha.
4. Kugadzikana:
CMC: Kazhinji yakagadzikana pamusoro pehuremu hwakawanda hweh uye tembiricha. Inogona kutsungirira mwero mwero emagetsi.
HPMC: Yakawanda yakagadzikana kupfuura cmc pasi pemamiriro ezvinhu emicic, asi inogona kufungidzira hydrolysis pasi pemamiriro ezvinhu eALKALINE. Izvo zvakare zvine hanya nekuzvibata kwezvibvumirano, izvo zvinogona kukonzera magazini kana kufungidzira.
5. Chikumbiro:
CMC: Inonyanyisa kushandiswa seThickener, STabilizer uye Wemvura-Kuchengetedza Mumiriri Muchando (sosi), senge mapiritsi (akadai sekrisheni (yakadai sekrincicical (yakadai sekrincicical (yakadai sekrincicical (yakadai sekrincicical (yakadai sekrincicical (yakadai sekrincicical (yakadai sekriniki (yakadai sekrini, lotion) maindasitiri.
HPMC: inowanzoshandiswa mune zvekuvaka (semuenzaniso, sile tile adometives, plmaceuticals (semuenzaniso, mahwendefa, gadziriso (ex, ziso, ziso, zvigadzirwa zveganda).
6. Kudenga uye kuchengeteka:
CMC: Kazhinji inozivikanwa seyakachengeteka (gras) nemabatiro ekudzora pakashandiswa mukati memoyo akatsanangurwa muchikafu uye mishonga yekushandisa. Iyo biodegradable uye isiri-ine chepfu.
HPMC: zvakare inofungidzirwa kuti yakachengeteka pakushandisa mukati mekurumbidzwa. Iyo inokwanisika uye inoshandiswa zvakanyanya mumunda wemishonga seyekudzoserwa mumiriri uye piritsi binter.
7. Mutengo uye Kuwanika:
CMC: Kazhinji mutengo unobata kupfuura HPMC. Inowanikwa nyore nyore kubva kune vaunosiyana vatengesi pasi rese.
HPMC: zvishoma zvishoma zvinodhura nekuda kwekugadzirwa kwayo kwekugadzira uye dzimwe nguva kushoma kubva kune vamwe vatengesi.
8. Enviripo Imimba:
CMC: BioDogradable, inotorwa kubva mukuvandudza zviwanikwa (cellulose). Zvinoonekwa sewakatarisana neushamwari.
HPMC: zvakare biodegradable uye inotorwa kubva ku cellulose, saka zvakare zvakatipoteredza hushamwari.
Ose maviri CMC uye HPMC ine zvakasarudzika zvivakwa zvinovaita zvinokosha muindasitiri akawanda. Iko kusarudzwa pakati pavo kunoenderana nezvakananga application zvinodiwa senge solubility, viscosity, kugadzikana uye mutengo kufunga. Muzhinji, CMC inogona kunge ichisarudzwa nekuda kwemutengo wayo wepazasi, yakawedzera pH yakasungirirwa, uye kukodzera kune chikafu uye cosmetic application. HPMC, kune rumwe rutivi, inogona kunge iri kufarirwa nekwavo yepamusoro vhiza Pakupedzisira, kusarudzwa kunofanira kuve kwakavakirwa pakufunga kwakazara kwezvinhu izvi uye kuwirirana nekushandiswa kwakarongedzwa.
