Ndeupi musiyano pakati pe cellulose uye hpmc?

Cellulose uye hydroxyprusyl methylcellose (HPMC) zvese zvakakosha makomputa ane mashandiro akasiyana-siyana, kunyanya mumaindasitiri akadai sechechi, chikafu, zvidyarwa, uye kuvaka. Nepo vachigovana zvimwe zvakafanana, vanewo mutsauko wakasiyana maererano nechimiro chavo chemakemikari, zvivakwa, zvinoshandiswa, uye maitiro ekugadzira.

1.comemical chimiro:

Cellulose:
Cellulose is polysaccharide inosanganisira maketani marefu emamolekora akabatana pamwe chete ne β-1,4-gollsidic zvisungo. Icho chinhu chikuru chechirwere chemadziro emasero, kupa rutsigiro rwechimiro uye kuomarara kudyara matishu. Cellulose Molecules fomu microfilibrils kuburikidza neHydrogen kusungwa, kupa kune simba uye kusanzwisisika kwemvura mumvura uye yakawanda organic sol sol.

HpMC:
HydroxyPropyl methylcellose (HPMC) iri hafu-synthetic polymer yakabviswa kubva ku cellulose kuburikidza nemakemikari kugadziridzwa. Iyo inogadzirwa nekurapa cellulose ine procleene oxide uye methyl chloride kuti uise hydroxyprospropropropyl uye mapoka mapoka kune iyo cellulose backbone. Dhigirii rekutsiva

2.Properties:

Cellulose:
Insolubility: yakachena cellulose haina kujekesa mumvura uye organic sol sol soles nekuda kwekuwedzera hydrogen yekubatanidza uye crystalline chimiro.
Biodegradability: Cellulose iri biodegradable, ichiita kuti ive neushamwari uye yakakodzera kune dzakasiyana siyana dzeco-hushamwari.
Simba reMuimbe: Ma Cellulose Mota ine High Simba, inopa kushandisa kwavo mapepa, machira, uye zvigadzirwa zvemavara.
Kushaikwa kwekugadzirisa: cellulose iri nemakemikari inter uye haireve kuita mamwe makomendi ari pasi pemamiriro ezvinhu akajairwa.

HpMC:
Solubility: HPMC inoratidza solubility mumvura, kugadzira pachena uye viscous mhinduro. Iyo solubility inotsamira pazvinhu zvakadai senge degree rekutsiva, zvinyoro-nyoro uremu, uye tembiricha.
Film Foration: HPMC inogona kuumba mafirimu anochinjika uye anoongorora mafirimu ekuomesa, achiita kuti ibatsire mumapfunde emishonga, kurongedza chikafu, uye zvimwe zvinoshandiswa.
Viscosity: HPMC Solutions ine inogadzirisa viscosity zvichienderana nezvinhu zvakadai sekusimbirira, tembiricha, uye degree rekutsiva. Ichi chivakwa chakakosha pakudzora maitiro ekunyepedzera.
Bioadhesion: HPMC ine bioadhesive zvivakwa, ichibvumira kuomerera kune nzvimbo dzekubereka senge mucosal membranes. Iyi ficha inobiridzirwa mune mishonga yemishonga yekudzoreredzwa kwezvinodhaka kutumira.

3.Application:

Cellulose:
Pepa uye kadhibhodi: Cellulose Fibers ndiyo yekutanga mbichana yezvinyorwa zvepepa uye kadhibhodi yekugadzirwa nekuda kwehuwandu hwavo uye simba.
Zvinyoro: Cotton, Chisiko cheFiber chakanyudzwa kunyanya chemheremalose, inoshandiswa zvakanyanya mune indasitiri yemiindaniso yechipfeko, upholstery, uye zvimwe zvigadzirwa-zvakaburitswa.
Zvivakwa zvekuvaka: Cellulose-based-based zvigadzirwa zvakaita sehuni, plywood, uye chidimbu chiuno chakajairika mukuvakidzana kwechimiro uye chinoshongedza zvinangwa.
Zvekudya zvekudya: Cellulose Derivatives senge microcrystalline Cellen Cellen Cellerose inoshandiswa senhau, Stabilizer, uye vamiririri vezvikepe mune zvigadzirwa zvekudya.

HpMC:
Formaceutical Formation: HPMC yakashandiswa zvakanyanya mumishonga yemishonga seyekuchinjika, yefirimu yaimbodzorwa, uye mashoni, macaps, ophthalmes mhinduro, uye mafomu epamusoro.
Zvivakwa zvekuvaka: HPMC inowedzerwa kune zvigadzirwa-zvakavakirwa zvigadzirwa senge motsa, tile anomisheni, uye kuzvimanikidza mishonga yekuzvivandudza kudzokorora, kudzokorora kwemvura, uye kudedera.
Indasitiri yeChikafu: HPMC inoshandirwa seyekupedzisira, emulsifieri
Zvigadzirwa zvega zvega: HPMC inowanikwa mune cosmetics, zvimbudzi, uye zvinhu zvega zvega zvakadai sosi, shampoos, uye mazino modifier, uye yechiMulsifier aimbova.

4.Mumacester Process:

Cellulose:
Cellulose inowanika kubva pane zvikafu zvinyorwa kuburikidza nemaitiro akadai sekumuchina kudhonzwa Iyo inobviswa cellulose inovanzika uye kugadzirisa kuti uwane mafomu akasiyana siyana akakodzera kune akasiyana maficha.

HpMC:
Iko kugadzirwa kweHPMC kunosanganisira matanho akati wandei, kutanga nekuwedzera kwemheremellose kubva pakudyara masango akadai sehuni protp kana machira ekotoni. Iyo cellulose inozorwiswa neAlkali yekubvisa kusvibiswa usati waita shanduko yekuchinja uye methyl chloride Iyo HPMC inokonzerwa yakanatswa, yakaoma, uye yakanyorwa muhukuru hwaunoda kushanduka kwekutengeserana.

cellulose uye hpmc pane ese akakosha makomputa ane zvisizvo zvinoshandiswa maindasitiri akasiyana siyana. Nepo cellulose polysaccharide inowanikwa mune chirimwa madziro emasero, HPMC yakagadziridzwa inobva kune cellulose ine yakasarudzika yekugadzirisa uye kushanda. Kusiyana kwavo mumakemikari chimiro, zvivakwa, zvigadzirwa, uye zvigadziriso zvinovaita zvinoita kuti vashandiswe musiyano, kugadzirwa kwechinyakare uye kugadzirwa kwemberi kune yepamusoro mishonga yekugadzira mishonga uye zvigadzirwa zvekuvaka. Kunzwisisa izvi kusarongeka kwakakosha kuti uwedzere kusarudzika huwandu hwesero e cellulose uye hpmc mukukudziridza zvigadzirwa zvemhando uye zvinogadziriswa mhinduro.
