CMC (sodium carboxymethyl cellulose) uye HPMC (hydroxypropyl methyl cellulose) maviri anowanzo shandiswa cellulose derivatives, ayo anoshandiswa zvakanyanya mumaindasitiri akasiyana. Kana iri imwe iri nani, zvinoenderana neiyo chaiyo application mamiriro uye zvinodiwa.
1. Chemical properties
CMC is anionic water-soluble polymer compound inowanikwa nekurapa natural cellulose ne sodium chloroacetate pasi pe alkaline mamiriro. Mapoka eCarboxymethyl anounzwa mukati mayo mamorekuru cheni, izvo zvinoita kuti ive yakanaka solubility yemvura uye kukora zvivakwa.
HPMC is a non-ionic cellulose ether inowanikwa nekuita cellulose ine methyl chloride uye propylene oxide. Iwo methoxy uye hydroxypropoxy mapoka mune mamorekuru chimiro cheHPMC anoipa kunaka kukora, kugadzikana uye kuchengetedza mvura, uye zvakare yakanaka yekupisa gel zvivakwa.
2. Minda yekushandisa
Indasitiri yezvekudya: CMC inowanzoshandiswa muchikafu seyakakora, stabilizer, suspending agent uye emulsifier, nezvimwewo, uye inowanzowanikwa muyoghurt, ice cream, jelly, zvinwiwa uye zvakabikwa. Inogona kuwedzera kuumbwa kwechikafu uye kuwedzera hupenyu hwesherufu. Kunyangwe HPMC ichishandiswawo muindasitiri yezvekudya, inonyanya kushandiswa sekuwedzera kune chikafu fiber, kunyanya mune zvimwe zvigadzirwa zvisina gluten.
Indasitiri Yemishonga: HPMC inoshandiswa zvakanyanya muindasitiri yemishonga, kunyanya mukuputira piritsi, inodzorwa-inoburitsa mishonga uye kugadzirwa kwekapisi. Yayo isiri-ionic zvimiro uye yakanaka biocompatibility inopa iyo yakasarudzika mabhenefiti mumasisitimu ekutumira zvinodhaka. CMC inoshandiswawo muindasitiri yemishonga, asi zvakanyanya seyakakora uye inonamira yemishonga.
Indasitiri yekuvaka uye yekupotera: HPMC inoshandiswa zvakanyanya mukuvaka, kunyanya mudhaka rakaoma, gypsum, uye putty poda, nekuda kwekuchengetedza kwayo kwemvura kwakanaka, kukora uye anti-slip zvivakwa. CMC zvakare ine mamwe maapplication muindasitiri yekukoira, asi inonyanya kushandiswa seyakakora yemvura-yakavakirwa machira.
Zvizoro uye kuzvitarisira pachedu: HPMC inowanzoshandiswa muzvizoro, kunyanya mumafuta ekuzora, makirimu, shampoos uye mushonga wemazino, semukobvu, emulsion stabilizer uye moisturizer. CMC inoshandiswawo mumashandisirwo akafanana, asi iyo moisturizing maitiro haina kunaka seHPMC.
3. Maitiro ekuita
Kunyungudika kwemvura: CMC inogona kunyatsonyungudika mumvura inotonhora uye inopisa, nepo HPMC ichinyungudika nyore mumvura inotonhora, asi isinganyungudika mumvura inopisa uye ine thermal gelation. Naizvozvo, HPMC inonyanya kukodzera kune zvigadzirwa zvinoda thermal gelation properties mune mamwe maapplication, akadai seanodzorwa-kuburitswa mahwendefa mumishonga.
Viscosity control: CMC ine yakaderera viscosity uye iri nyore kudzora, nepo HPMC ine yakakura viscosity siyana uye inochinjika. HPMC inogona kupa yakakwira viscosity uye irambe yakagadzikana patembiricha dzakasiyana, izvo zvinoita kuti zvive zvakanyanya kubatsira mumashandisirwo anoda chaiyo viscosity control.
Kugadzikana: HPMC ine kugadzikana kwemakemikari kuri nani pane CMC. Inoratidza kugadzikana kwakanaka munzvimbo dzine acidic kana alkaline, nepo CMC inogona kudzikisira mumaasidhi akasimba kana mabhesi akasimba.
4. Mutengo uye mari
Kazhinji, CMC yakachipa uye yakakodzera kune akakura maindasitiri ekushandisa, nepo HPMC iri kudhura nekuda kwekuoma kwayo kugadzira uye mutengo wakakura. CMC inogona kunyanya kukwezva mumamiriro ezvinhu apo huwandu hukuru hunodiwa uye mutengo unonzwisisika. Nekudaro, mune mamwe minda ine yakanyanya kuita zvinodiwa, senge mushonga uye yepamusoro-yekupedzisira cosmetics, HPMC ichiri kushandiswa zvakanyanya nekuda kweyakasarudzika mabhenefiti ekuita kunyangwe mutengo wayo wakakwira.
5. Kuchengetedzwa kwezvakatipoteredza uye kuchengeteka
Ose ari maviri CMC neHPMC ane yakanaka biodegradability uye kuchengetedzwa kwezvakatipoteredza, uye ane zvishoma zvinokanganisa nharaunda panguva yekushandiswa. Ose ari maviri anoonekwa seakachengeteka chikafu uye ekuwedzera zvinodhaka, uye anogona kushandiswa zvakachengeteka muzvigadzirwa zvakasiyana mushure mekutariswa kwakasimba uye chitupa.
CMC neHPMC vane zvazvakanakira nezvazvakaipira, uye hazvibviri kungotaura kuti ndeipi iri nani. Zvekushandisa zvinoda mutengo wakaderera, kugadzirwa kwakakura, senge indasitiri yechikafu uye zviri nyore kukora zvinodiwa, CMC isarudzo inodhura. Muminda ine hunyanzvi hwekuita zvinodiwa, senge mishonga inodzorwa kuburitsa masisitimu, yepamusoro-yekupedzisira zvivakwa zvekuvaka uye zvemhando yepamusoro zvekuzora, HPMC inogona kuve yakakodzera zvakanyanya nekuda kwekuita kwayo kwakanaka. Naizvozvo, kusarudzwa kweiyo cellulose derivative zvinoenderana nezvinodiwa zvekushandisa, zvinodiwa zvekuita uye kutariswa kwemutengo.
