Hydroxyprupyl methylcellose (HPMC)is a synthetic cellulose inobviswa uye hafu-synthetic polymer compind. Inoshandiswa zvakanyanya mumaindasitiri mazhinji akadai sekuvaka, mushonga, chikafu, cosmetics uye hukuru. Senge isiri-ionic cellulose ether, Hpmc ine yakanaka mvura solubility, firimu-inoumba zvivakwa, kusungirirwa uye kune kukosha kwakakosha kwekushandisa muminda yakawanda.
1. Chemical chimiro uye zvivakwa zveHPMC
Iyo moleky chimiro cheHPMC inotorwa kubva kune yakasikwa cellulose. Mushure mekugadziriswa kwemakemikari, methyl (-Och₃) uye hydroxyprupyl (-Och₂ch₂ch₂oh) mapoka anounzwa muCellulose Chain. Yayo yekutanga makemikari chimiro chiri seinotevera:
Cellulose mamorekuru anoumbwa neye glucose zvikamu zvakabatana ne β-1,4-glycsics zvisungo;
Methyl uye hydroxypruspropyl mapoka anounzwa muCellulose keteni kuburikidza nekutsiva maitiro.
Ichi chimiro chemakemikari chinopa HPMC zvinotevera zvivakwa:
Solubilogity yemvura: Nekudzora iyo degree rekutsiva methyl uye hydroxypruspropyl mapoka, HPMC inogona kugadzirisa maitiro ayo emvura. Kazhinji, HPMC inogona kuumba mhinduro yeViscous mumvura inotonhora uye ine yakanaka mvura solubility.
Kugadziriswa kweViscosity: Iyo viscosity yeHPMC inogona kuve yakanyatso kudzorwa nekugadzirisa iyo molecular uremu uye degree rekutsiva kuti usangane nezvinodiwa zvakasiyana.
Kupisa kupokana: Sezvo HPMC iri thermplastic polymer zvinhu, kupokana kwayo kupisa kwakanyatsonaka uye kunogona kuchengetedza kuita kwakagadzikana mukati meimwe tembiricha yekupisa.
BiocompriChiction: HPMC chinhu chisiri chepfu uye chisiri-chinotsamwisa, saka chinonyanya kufarirwa mumunda wekurapa.
2. Kugadzirira nzira yeHPMC
Iyo yekugadzirira nzira yeHPMC inonyanya kuzadzikiswa neiyo itsurity yekuita cellulose. Matanho chaiwo ari seanotevera:
Cellulose Dissolution: Kutanga, Sanganisa zvakasikwa cellulose ine solvent (senge solorform, doro solvent, etc.) kuti uzvinyore muCellulose Solution.
Chemical shanduko: Methyl uye hydroxyprupyl makemikari reegents (senge chlomethyl compounds uye allyl doro) anowedzerwa kune mhinduro yekutsiva.
Kusarerekera uye kuoma: Iyo PH Kukosha kunogadziriswa nekuwedzera acid kana Alkali
3. Main main application yeHPMC
Izvo zvakasarudzika zvivakwa HPMC zvinoita kuti zvive zvakanyanya kushandiswa muminda yakawanda. Izvi zvinotevera ndedzimwe nzvimbo huru dzekushandisa:
. " Inogona kuvandudza fluidity, kuderedza uye kuchengetwa kwemvura kwemusanganiswa. Kunyanya mune yakaoma moturu, HPMC inogona kuvandudza kuita kwekuvaka, kuwedzera kuderedza kwemutya, uye kudzivirira marara mumusimbe slurry panguva yekuomesa.
(2. Semumiriri wefirimu-kugadzirwa, thickener uye stabilizer, inogona kuvandudza iyo solubility uye bioavilalility yemishonga. Mapiritsi, HPMC haigone kungodzora huwandu hwezvinodhaka, asi zvakare kugadzirisa kusimba kwezvinodhaka.
. Semuenzaniso, mune yakaderera-mafuta-mafuta-emafuta-emahara chikafu, HPMC inogona kupa kuravira kuri nani uye kuwanda uye kuwedzera kugadzikana kwechigadzirwa. Iyo zvakare inoshandiswa zvakanyanya mune zvekudya zvakandochina kudzivirira kupatsanurana kwemvura kana kuti ice crystal yekuumbwa.
. Zvinogona kuvandudza kuumbwa kwezvizoro, kuriita kuti vakusi nyore kunyorera uye kutora. Kunyanya mumakiromita eganda, shampoos, kumeso masks uye zvimwe zvigadzirwa, kushandiswa kweHPMC kunogona kuvandudza manzwiro uye kugadzikana kwechigadzirwa.
. Inogona zvakare kuvandudza kudzikisira kwemvura uye kurwisa-kunyengedzwa kwekubatanidza, uye kuwedzera kuomarara uye kuderedza kwekucheka.
4. Tarisiro yeMusika uye Zvekuvandudza maitiro eHPMC
Sezvo vanhu vanobhadhara zvakanyanya uye kutarisisa kune dziviriro uye hutano, HPMC, segirini yegirini uye isina chepfu polymer, ine tarisiro yakakura. Kunyanya mune iyo mishonga, chikafu uye maindasitiri ezvekudya, kushandiswa kweHPMC kuchawedzera kuwedzerwa. Mune ramangwana, maitiro ekugadzira HPMC anogona kuve akagadziridzwa, uye kuwedzera kwekubuda uye kuderedzwa kwemutengo kuchakurudzira kunyorera kwayo mumaindasitiri akawanda.
Nekuvandudzwa kwezvinhu zvakangwara uye kudzorerwa tekinoroji, kushandiswa kweHPMC mu Smart Duff Scuter Systems kuchave zvakare kutsvagisa hotspot. Semuenzaniso, HPMC inogona kushandiswa kugadzirira vatakuri vezvinodhaka neanodzorwa kuburitsa basa kuti uwedzere nguva yezvinodhaka uye kugadzirisa kushanda.
