(Hydroxypropyl)methyl cellulose | CAS 9004-65-3

(Hydroxypropyl)methyl cellulose, inozivikanwawo nechidimbu chayo HPMC kana nhamba yayo yeCAS 9004-65-3, is cellulose ether inotorwa kubva kune yakasikwa cellulose. Iyo semi-synthetic polymer iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kweiyo yakasarudzika zvivakwa uye kuita zvakasiyana. Heino tarisisa pakomboni iyi:

Chimiro neZvinhu:
1 Mamiriro: HPMC inogadzirwa kuburikidza nekugadziriswa kwekemikari ye cellulose, uko zvese methyl (-CH3) uye hydroxypropyl (-CH2CHOHCH3) mapoka anounzwa pane cellulose musana.
2 Dhigirii reKutsiva (DS): Iyo dhigirii yekutsiva inoreva avhareji yenhamba yemapoka anotsiva paglucose unit mucheni ye cellulose. Inotaridza zvimiro zveHPMC, senge solubility, viscosity, uye kugona kugadzira firimu.
3 Zvivakwa: HPMC inoratidza zvivakwa zvakaita sekukora, kuchengetedza mvura, kuumbwa kwemafirimu, uye chiitiko chepamusoro. Izvo zvivakwa zvinogona kugadziridzwa nekudzora iyo DS panguva yekubatanidza.

Kugadzirwa:
1.Cellulose Sourcing: Cellulose, iyo yekutanga mbishi zvinhu zveHPMC, inotorwa kubva kune zvinogonekazve masosi sehuni pulp kana donje.
Etherification: Cellulose inopinda etherification, iyo inobatwa nepropylene oxide kuunza hydroxypropyl mapoka uyezve nemethyl chloride kuwedzera methyl mapoka.
2.Kunatsa: Iyo yakagadziridzwa cellulose inonatswa kuti ibvise kusvibiswa uye ne-zvigadzirwa, zvichiguma nekupedzisira HPMC chigadzirwa.
Applications:
3.Indasitiri yeKuvaka: HPMC inoshandiswa zvakanyanya mukuvaka zvinhu zvakadai semasimende-based mortars, plasters, uye mataira adhesives kuvandudza kushanda, kuchengetedza mvura, uye kunamatira.
4.Pharmaceuticals: Inoshanda sebinder, thickener, firimu yekare, uye stabilizer mumishonga yemishonga inosanganisira mapiritsi, capsules, ophthalmic solutions, uye topical creams.
5.Food Indasitiri: HPMC inoshanda seyakakora, stabilizer, uye emulsifier muzvigadzirwa zvekudya zvakasiyana-siyana senge sosi, mapfekero, ice cream, uye zvinhu zvakabikwa.
6.Cosmetics uye Personal Care: Muzvizoro uye zvigadzirwa zvekuchengeta munhu, HPMC inoshandiswa seyakakora, inomisa mumiririri, yekare firimu, uye moisturizer mumakirimu, lotions, shampoos, uye gels.
7.Paints uye Coatings: Inosimudzira viscosity, sag resistance, uye firimu rekugadzira zvinhu zvemvura-based paints, adhesives, uye machira.
Mhedziso:
(Hydroxypropyl) methyl cellulose, ine zvakasiyana-siyana zvekushandisa uye zvinobatsira zvivakwa, chinhu chakakosha muzvigadzirwa zvakawanda zveindasitiri nekutengesa. Basa rayo mukusimudzira mashandiro, kugadzikana, uye kushanda kweakasiyana magadzirirwo anoita kuti ive yakakosha muzvikamu zvakawanda. Sezvo maindasitiri ari kuramba achivandudza, kudiwa kweHPMC kunotarisirwa kuramba kuchienderera mberi, zvichifambisa kufambira mberi munzira dzayo dzekugadzira uye mashandisiro.
