Ndeipi iri nani, cmc kana hpmc?

Kunyatsoenzanisa uye kuongorora CMC (CarboxyMethyl Cellerose) uye HPMC (HPMC (HPMOXKYPROPYL YEMAHARA, Zvinoshandiswa, zvakanakira, zvakashata, uye kukodzera kune zvakaringana zvinangwa. Ose CMC uye HPMC are cellulose Detivatives inoshandiswa zvakanyanya mumasango akasiyana-siyana, kusanganisira mishonga yemishonga, chikafu, zvizoro, uye kuvaka. Imwe neimwe ine hunhu hwayo hwakasarudzika uye mabhenefiti, ayo anoona kukodzera kwavo kune chaiyo mafaro.

1. Nhanganyaya kuCMC uye HPMC:

Carboxymethyl Cellulose (cmc):
CMC imvura-soluble cellulose inobviswa kubva kune yakasikwa cellerose nekuunza carbolmeymethyl mapoka kune iyo cellulose backbone. Izvo zvinowanzoshandiswa seyenzi yakakora, stabilizer, uye yekuchengetwa kwemvura mumugodhi mune dzakasiyana-siyana maindasitiri.

Hydroxyprusyl methylcellose (HPMC):
HPMC ndeimwe yemvura-soluble cellulose inogadzirwa nekubata cellulose ine procylone oxide uye methyl chloride. Inoshandisa ma-application muMishonga, Chikafu, Cosmetics, uye kuvakwa nekuda kwekuita kwayo, firimu-kugadzira, uye kusunga midziyo.

2. Zvivakwa zvakafanana:

Solubility:
CMC: zvizere zvinyoronyoro mumvura.
HPMC: Inonyungudika mumvura iri pasi pemamiriro ezvinhu, kugadzira yakajeka kana zvishoma opalescent mhinduro.

Viscosity:
CMC: Inoratidza yakakwira viscosity kunyangwe pakadzika pakatarisana.
HPMC: viscosity inosiyana zvichienderana neiyo degree rekutsiva uye rinoswededza uremu.

Firimu-inogadzira zvivakwa:
Cmc: kugona kushoma-muviri muviri.
HPMC: Yakanakisa firimu-inogadzira zvivakwa, ichiita kuti iite yakakodzera kuti zvikurumidzi senge zvipfeko uye mafirimu.

Kugadzikana kweTermal:
CMC: Kazhinji kuderera kugadzikana kwekutonga kwakaenzaniswa neHPMC.
HPMC: Inoratidza zviri nani zvekutonga, zvichiita kuti zviite zvakakodzera kuti zviwedzere.

3.Application:

CMC application:
Indasitiri yeChikafu: Inoshandiswa seMubatanidzwa, STabilizer, uye kunyorovesa mumiririri muzvigadzirwa, zvipfeko, uye zvigadzirwa zveDoiry.
Mishonga yemishonga: akashandirwa mubhiramu piritsi semubhatani uye kuparadzanisa.
Zvigadzirwa zvega zvega: inowanikwa mumazino, kirimu, marara, uye zvidhori sedhizimusi uye stabilizer.
Mafuta anokwezva: anoshandiswa mukukweva kwemvura kudzora viscosity uye kurasikirwa kwemvura.

HpMc application:
Indasitiri yekuvaka: Inoshandiswa mumutero-basemed-based motsa, uye matanda eshi ekuvandudza kushanda uye kudedera.
Indasitiri yechechi yechechi: Yakashandiswa mune inodzorwa-kuburitsa zvinodhaka zvinodhaka masisitimu, mahwendefa ebiritsi, uye mhinduro yeOphtalmic.
Indasitiri yeChikafu: Inoshandiswa seanotenderedza, emulsififier, uye stabilizer mune zvigadzirwa sezvinhu zvinobhoti uye zvigadzirwa zvemukaka.
Cosmetics: inowanikwa mune zvigadzirwa senge shampoos, uye marara seyekuita mumiririri uye firimu aimbova.

4 Zvakanakira uye Zvakashata:

Zvakanakira CMC:
Yakakwira mvura solubility.
Yakanakisa kuremadza uye inosimbisa zvivakwa.
Mutengo-unoshanda.
Kushandisa kwakawanda mune dzakasiyana-siyana maindasitiri.

Zvinokuvadza zveCMC:
Kushoma firimu-kugadzira kugona.
Kuderedza kupaza kugadzikana kwakaenzaniswa neHPMC.
Inogona kuratidza kusarudzika kwemabasa zvichienderana nePH uye Electrolyte Constrenration.

Zvakanakira HPMC:
Yakanaka kwazvo firimu-inogadzira zvinhu.
Zviri nani zvekudyara.
Inopa yakavandudzwa kushamisika uye kushanda mune zvekuvaka zvinoshandiswa.
Yakakodzera kune inodzorwa-inoburitswa mishonga yemishonga.

Zvakaipa zveHPMC:
Mutengo wepamusoro uchienzaniswa neCMC.
Solubility inogona kusiyana zvichienderana nemamiriro egiredhi uye ekushandisa.
Kugadzirisa kunogona kuda chaiyo michina uye mamiriro.

5. Kukodzera kweiyo chaiyo application:

CMC:
Yakanakira mafaro anoda yakakwira mvura solubility uye inokakavara zvivakwa, zvakadai sechikafu uye zvigadzirwa zvega zvega.
Inokodzera kunyorera-tembiricha yekushisa uko iyo yekudzikisira kusasimba haisi basa rekutanga.
Yakashandiswa zvakanyanya mune mishonga yemishonga ipo yekukurumidza kushungurudzika kunodiwa.

HpMC:
Inodaidzwa kuti zvikumbiro zvinoda kuti zvibirirwe firimu-kugadzira mafirimu, akadai sejasi uye mafirimu mune maindasitiri emishonga uye ezvekudya.
Yakanyatsogadzirirwa zvekuvaka zvekuvaka nekuda kwekushambadzira kwayo kwakakwirira, kushanda, uye kugadzikana kwekunyora.
Inokodzera kuti isununguke-kuburitsa zvinodhaka zvinodhaka zvinoda kuti isunungurwe menderekedzo yekisiti.

6. Mhedziso:

Ose maviri CMC uye HPMC ivanhu vanokosha cellulose vanobva vane mitsipa yakasarudzika uye zvinoshandiswa. Sarudzo pakati peCMC uye HPMC zvinoenderana nezvinodiwa chaizvo seSalubility, viscossity, firimu-kugadzira kugona, uye kufunga kwemari. Ipo CMC inopa yakakwira mvura solubility uye yakanakisa yakakora midziyo, HPMC inodakarira mukuumbwa kwemafirimu, kugadzikana kwefirimu, uye kudedera. Kunzwisisa hunhu hwakasarudzika hwemumwe neumwe cellulose dervenative zvakakosha pakusarudza iyo yakakodzera chigadzirwa chechimwe chiitiko chekushandisa, chichiita chiitiko chakakwana uye mutengo-zvinobudirira.
