Hydroxyethylcellulose (HEC) isiri-ionic, mvura-inonyungudika polima inotorwa kubva muselulosi, iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana sezvizora, mishonga, chikafu, uye machira.Hunhu hwayo hwakasiyana hunoita kuti ive chinhu chakakosha mumigadziriso yakawanda, kusanganisira seyakakora, emulsifier, uye stabilizer.Imwe yezvinonetsa zvinowanzoitika ine hydroxyethylcellulose chimiro chayo chekunamira.
Kunzwisisa Hydroxyethylcellulose (HEC)
Mamiriro neZvinhu
HEC inogadzirwa ne etherification ye cellulose ine ethylene oxide, zvichikonzera iyo hydrophilic polymer ine yakanakisa inosunga mvura.Iyo dhigirii yekutsiva (DS) yemapoka ehydroxyethyl pane cellulose musana inosarudza kunyungudika kwayo, viscosity, uye humwe hunhu.Kazhinji, huwandu hweDS hwepamusoro hunotungamira mukunyungudika kwemvura uye viscosity.
Applications
Cosmetics: HEC inoshandiswa zvakanyanya mukugadzira zvizorwa senge lotions, makirimu, shampoos, uye gels seyakakora mumiriri, emulsifier, uye stabilizer.Inowedzera kuumbwa kwechigadzirwa, inopa kupfava, uye inovandudza ruzivo rwesero yekunzwa.
Pharmaceuticals: Mumishonga, HEC inoshandiswa mumhando dzakasiyana dzeyero inosanganisira mafuta, kumiswa, uye zvinwiwa zvemukanwa nekuda kwekukora uye kumisa zvinhu.
Indasitiri Yezvekudya: HEC inoshandiswa muzvigadzirwa zvechikafu kugadzirisa magadzirirwo, kudzikamisa emulsions, uye kudzora viscosity mumashandisirwo akaita soso, madhirezi, uye zvinwiwa.
Kuzvichengeta Pamunhu: Kunze kwezvizoro, HEC inowana zvikumbiro muzvigadzirwa zvekuchengeta zvega senge mushonga wemazino, magadzirirwo ekuchengeta bvudzi, uye zvigadzirwa zvehutsanana.
Zvinhu Zvinokonzera Kunamira
Kuisa pfungwa: Kukwirira kwepamusoro kweHEC kunogona kukonzera kuwedzera kunamatira nekuda kwekubatana kukuru pakati pemaketani epolymer, zvichikonzera mhinduro yakawanda.
Tembiricha: Kunamira kunogona kusiyana nekushanduka kwetembiricha.Pakupisa kwepamusoro, HEC mhinduro dzinowanzova mvura yakawanda, kuderedza kunamira, nepo tembiricha yakaderera inogona kuwedzera viscosity uye kunamira.
pH: pH inogona kukanganisa kunyungudika uye viscosity yeHEC mhinduro.Yakanyanya pH mamiriro anogona kukonzera HEC kudonha kana kuumba gels, inokanganisa kunamatira.
Additives: Zvimwe zvinongedzo mukugadzirisa zvinogona kuwirirana neHEC, kuchinja maitiro ayo.Masurfactants, munyu, uye maelectrolyte anogona kukanganisa kunyungudika uye viscosity yeHEC mhinduro, zvichikonzera kunamira.
Mazano Ekugadzirisa Kunamira
Optimize Formulation: Kugadzirisa kuwanda kweHEC uye zvimwe zvinongedzo mukugadzira zvinogona kubatsira kudzora kunamira.Kunyatsogadzirisa chiyero cheHEC kune zvimwe zvikamu zvinogona kuwana inodiwa manyorerwo uye viscosity.
Kudzora Tembiricha: Kutarisisa uye kudzora tembiricha yekugadzirisa kunogona kukanganisa rheological maitiro eHEC mhinduro, kuderedza kunamatira panguva yekugadzira.
pH Kugadziriswa: Kuve nechokwadi chekuti maumbirwo ari mukati meiyo yakakwana pH renji yekunyungudika kweHEC uye kugadzikana kunogona kudzivirira nyaya dzakadai sekunaya uye kuumbwa kwegel, nekudaro kuderedza kunamira.
Kushandisa Kwekuwedzera Zvisungo: Kubatanidza zvinowedzerwa senge makobvu, emollients, kana humectants zvinogona kugadzirisa magadzirirwo uye kuderedza kunamira uku uchiwedzera kuita kwese kwechigadzirwa.
Particle Kuderedza Kukura: Kugadzirira HEC mhinduro neakatsetseka particle saizi anogona kuvandudza kupararira uye kuderedza kunamira nekusimudzira kudyidzana kuri nani nezvimwe zvinongedzo.
Homogenization: Homogenizing HEC mhinduro dzinogona kubatsira kuwana yunifomu kupararira kwepolymer, kuderedza mukana wekudonha uye kunamira.
Hydroxyethylcellulose i polymer inogoneka ine akawanda maapplication mumaindasitiri akasiyana siyana.Kunyange ichipa mabhenefiti akakosha senge kukora, kudzikamisa, uye emulsifying zvivakwa, kunamira dzimwe nguva kunogona kuve kunetseka, kunyanya mukuumbwa uko magadzirirwo uye hunhu hwekunzwa hunokosha.Kunzwisisa zvinhu zvinopesvedzera kunamira uye kushandisa nzira dzakakodzera kuzvibata kunogona kuve nechokwadi chekushandiswa kunobudirira kweHEC mukushandisa kwakasiyana, kuwedzera kushanda kwechigadzirwa uye kugutsikana kwevatengi.
nepo hydroxyethylcellulose inogona kuratidza kunamatira pasi pemamwe mamiriro ezvinhu, dhizaini yakakodzera yekugadzira, kudzora tembiricha, pH kugadziridzwa, uye kushandiswa kwezvinhu zvinopindirana zvinogona kuderedza nyaya iyi, zvichibvumira kushandiswa kwakanyanya kweHEC mumashandisirwo akasiyana siyana.
