HPMC (HYDROXYPROPYL MetHylcellose) uye CMC (CarboxyMethyl Cellelose) Zvinowanzoitwa Cellulose Derivatives, inoshandiswa zvakanyanya muchikafu, mishonga, mishonga, kuvaka uye mamwe minda.
1. Chemical chimiro uye nzira yekugadzirira
HpMC:
Chemical dhizaini: HPMC ndeye Synthetic Polymer yakawanikwa nekuita zvisikwa zvakasikwa pamwe neProfyle oxide uye methyl chloride mushure mekurapwa kweAlkali.
Iyo huru yeyunivhesiti ndiyo yeglucose mhete, iyo yakabatana ne 1,4-β-β-glucosic zvisungo, uye mamwe mapoka ehydroxyl anotsiviwa neiyo nzira (-Och₃) uye hydroxypruppropyl (-ch₂chichch₃).
Kugadzirira nzira: Kutanga, cellulose inobatwa neSodium Hydroxide Solution yekuumba Alkali Cellalose, uye propylive oxide, uye pakuronga oxide, uye pakupedzisira zvisina kurongeka, kushambidzwa uye kwakaomeswa kuwana hpmc.
CMC:
Chemical Staturation: CMC ndeye anonic cellulose inobva yakawanikwa nekuita cellulose ine chloroacetic acid pasi pealkaline mamiriro.
Iyo huru yeyunivhesiti yeyunivhesiti zvakare chindori cheGlucose, chakabatana ne1,4-β-β-glucosic zvisungo, uye mamwe mapoka ehydroxyl anotsiviwa neCarboxymeym (-ch₂coh).
Maitiro ekugadzirira: Cellulose anowana neSodium Hydroxide kuumba Alkali Cellalose, iyo inozoshandisa neChloroacetic acid, uye pakupedzisira inzwa, kushambadzira uye kuoma kuwana cmc.
2. Zvepanyama uye zvemakemikari zvivakwa.
Solubility:
HPMC: Inonyura mumvura inotonhora uye imwe organic sol soles, kusakwana mumvura inopisa. Kana mhinduro yacho yaputswa, iyo gel yakajeka inogona kuumbwa.
CMC: Inonyungudika mumvura inotonhora uye mvura inopisa kuti iite viscous cooludal mhinduro.
Viscosity uye rheology:
HPMC: ine yakanaka yakakora mhedzisiro uye kumiswa kugadzikana mumvura mhinduro, uye ine pseudoplastic (shear inotetepa) rheological.
CMC: ine yakakwira viscosity uye yakanaka rheological zvivakwa mumamiriro ekunze, kuratidza thiskitropy (kuremedza kana kuiswa kana kutetepa kana kuchimanikidzwa) uye pseudoplastical.
3. Masango ekushandisa
HpMC:
Indasitiri yeChikafu: Sezvo thickener, stabilizer, emulsifier uye yefirimu yaimbova, inoshandiswa mune ice cream, deny zvigadzirwa, jelly, nezvimwe.
Indasitiri yechechi yechechi: Inoshandiswa seBinder, kuparadzanisa uye kudzorwa kusunungurwa mumiririri wekugadzirira piritsi.
Zvivakwa zvekuvaka: Inoshandiswa muComent Mortar uye Gypsum zvigadzirwa kuti uvandudze kuchengetwa kwemvura uye kushanda.
Cosmetics uye yega yega zvigadzirwa zvezvigadzirwa: Inoshandiswa muzvimedu, maFiros, Shampoos uye Shageji uye etc., kuti ape madhara nekutsausa uye kusimbisa.
CMC:
Indasitiri yekudya: Sezvo thickener, stabilizer uye emulsifieri, inoshandiswa muJam, jelly, ice cream uye zvinwiwa.
Indasitiri yechechi yechechi: Inoshandiswa seBinder, kupaza masaga emishonga uye yefirimu yaimbova yemishonga yemishonga yemishonga.
Indasitiri yepepuru: Inoshandiswa semunyoro weSimba mumiririri uye Sosi yekubatira mumiririri kuti uvandudze simba rakaoma uye kudhindwa kwepepa.
Industrae indasitiri: Inoshandiswa sekurongedza mumiririri uye kupedzisa mumiririri kuti uvandudze iyo simba uye gloss yemachira.
Dailymical Kemical Indasitiri: Inoshandiswa seThickener uye Stabilizer yeConstgents, mazino uye zvigadzirwa zveganda.
4. Kudzivirirwa kwezvakatipoteredza uye kuchengeteka
Zvese HPMC uye CMC hazvisi zvekushongedza zvinhu zvisina kujairika zvisingaitike nekugaya enzymes mumuviri wemunhu uye zvinowanzoonekwa zvakachengeteka zvekudya uye zvinowedzera zvekudya zvinowedzera. Ivo vanonunurwa zviri nyore munharaunda uye vane kusvibiswa kushoma kune zvakatipoteredza.
5. Mutengo uye Soko Kuwanikwa
HPMC inonyanya kushandiswa muminda ine yakakwirira performance zvinodiwa nekuda kwekugadzirira kwayo kugadzirira maitiro, yakagadzirirwa kugadzirwa kwemutengo uye mutengo wakakwira.
Iyo yekugadzira maitiro eCMC iri nyore, mutengo wakaderera, mutengo unodzikama, uye huwandu hwekushandisa hwakafara.
Kunyangwe HPMC uye CMC iri mese cellulose detivatives, ivo vanoratidza maitiro akasiyana uye anoshandisa nekuda kwezvivakwa zvavo zvakasiyana zvemakemikari, physicochemical zvivakwa uye minda yekushandisa. Sarudzo yeiyo cellulose inobva yekushandisa inowanzoenderana nezvinodiwa chaizvo zvekushandisa uye kufunga kwehupfumi.
