Ndeupi musiyano uripo pakati peHPMC uye MHEC?

HydroxyPropyl methylcellose (HPMC) uye methylhydroxyl Cellenyl Cellulosel Cellulosel Cellulose Nepo ivo vane kufanana, ivo vanoratidzawo misiyano mikuru.

Hydroxyprusyl methylcellose (HPMC):

1.comemical chimiro:
HPMC ndeye semi-synthetic polymer inotorwa kubva ku cellulose.
Iyo ine zvikamu zvekudzokorora zveAnhydroglucose chakabatanidzwa neHydroxypruppropyl uye mapoka emhando.

2. Performance:
Solubl Solubility: Hpmc inochenesa mumvura uye saka inoshandiswa zvakanyanya mune dzakasiyana siyana mafambiro.
Firimu kuumba: Inogona kuumba mafirimu akaonda, ichiita kuti zviite kuti zvibodzwa zvinoda kuti zviitwe zvekudzivirira.
Kurohwa kwehombodo: ine mafuro ekubaya, ayo anogona kunge ari kubatsira mune zvimwe zvekushandisa.

3. Chikumbiro:
Mishonga: Inoshandiswa seBinders, Mafirimu efirimu uye akasimbiswa-anoburitsa matrices mumapiritsi emishonga yemishonga.
Indasitiri yekuvaka: Inoshandiswa muComent-based Tile Athesivives, Gypsum-based mapurasitiki uye kuzvimanikidza pachako.
Indasitiri yechikafu: Inoshandiswa seanotsigira uye stabilizer mune chikafu.

4. Kugadzira:
Iyo inogadzirwa nekutsva kwe cellulose ine procylene oxide uye methyl chloride.
Dhigirii rekutsiva

Methylhydroxylylcellose (mhec):

1.comemical chimiro:
MheC iri zvakare cellulose inobva nehydroxyethyl uye nzira mapoka akasungirirwa kune cellulose backbone.

2. Performance:
Solubl Solubility: Sa HpMC, MheC imvura inonyura, inopa kune yaisanganisira kuwanda mune dzakasiyana siyana dzekushandisa.
Kuvandudzwa Kwemvura Kuchengetwa: MheC Kazhinji kuratidzira Kuchengeta Kwekuvandudza Kwemvura Kupfuura HPMC.

3. Chikumbiro:
Indasitiri yekuvaka: Yakanyanya kushandiswa seyekuita mumiriri weiyo coment-based motsa, tile ainesivives uye gypsum-based zvigadzirwa.
Pendi uye Mabhonzo: Zviito seRheology Modifier mune mvura-yakavakirwa mapepa uye majasi.
Pharmaceutical: Inoshandiswa kune inodzorwa yakadzorwa kuburitsa gadziriro yemishonga.

4. Kugadzira:
Inogadzirwa neiyo itsera ye cellulose ine methyl chloride uye etyl chloride.
Iyo degree rekutsiva rinokanganisa zvivakwa uye kuita kweMheCS.

Musiyano uripo pakati peHPMC uye MheC:

1. Kuwedzera maitiro:
HPMC iri synthekised uchishandisa Propylene oxide uye methyl chloride.
MheC inogadzirwa uchishandisa methyl chloride uye etyl chloride.

2. Kuchengeta mvura:
MheC kazhinji inoratidzira zvirinani kudzokorora kwemvura pane hpmc.

3. Chikumbiro:
Kunyange paine zvimwe zvinopfuura, chinongedzo chaicho chinogona kufadza imwe pamusoro peimwe yakavakirwa pane izvo zvakasiyana hunhu.

4. Thermal Glation:
HPMC inoratidza thermogelling zvivakwa, nepo mhec inogona kunge iine maitiro akasiyana maitiro.

HPMC naMEC vane huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana-siyana, uye imwe neimwe ine zvakaringana zvakanaka. Iko kusarudzwa pakati pavo kunoenderana nezvinodiwa zvekushandisa uye zvinodikanwa. Kunyangwe mune mishonga, kuvaka kana imwe minda, kunzwisisa misiyano kunobatsira kuita sarudzo dzevazivikanwa kuti uwane maitiro akakwana mune akasiyana maitiro uye maitiro.
