Hydroxyethyl cellulose (HEC) isiri-ionic, mvura-inonyungudika polima inotorwa kubva muselulosi, iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana semishonga, zvekuzora, chikafu, uye kuvaka. Hunhu hwayo hwakasiyana hunoita kuti ive yekuwedzera yakakosha muzvigadzirwa zvakawanda. Chimwe chinhu chinowanzoitika pamusoro peHEC ndeyekunamatira kwayo.
Nhanganyaya yeHydroxyethyl Cellulose (HEC)
HEC inotorwa kubva kune cellulose, inongoitika polima inowanikwa muzvirimwa. Kuburikidza nemakemikari maitiro, ethylene oxide inowedzerwa kune cellulose kugadzira hydroxyethyl cellulose. Uku kugadziridzwa kunopa kunyungudika kwemvura uye zvimwe zvinodikanwa zvivakwa kune iyo polymer.
Zvivakwa zveHEC
Kunyungudika kweMvura: Chimwe chezvinhu zvinonyanya kuzivikanwa zveHEC kugona kwayo kunyungudika mumvura, ichigadzira mhinduro dzakajeka, dzakajeka. Izvi zvinoita kuti zvive zvakasiyana-siyana mumagadzirirwo emvura.
Viscosity: HEC mhinduro dzinoratidza yakakwira viscosity, iyo inogona kugadzirwa nekugadzirisa zvinhu zvakaita se polymer concentration, dhigirii rekutsiva, uye mhinduro pH.
Thickening Agent: Nekuda kwekukwirira kwayo viscosity, HEC inowanzoshandiswa seyakakora mumiriri mune akasiyana maapplication akadai pendi, anonamira, uye zvigadzirwa zvekuchengeta munhu.
Firimu Magadzirirwo: HEC inogona kuumba anochinjika, akajeka mafirimu kana akaomeswa, achiita kuti abatsire mukupfeka uye mafirimu nekuda kwezvinangwa zvakasiyana.
Zvikumbiro zveHEC
Cosmetics: HEC inoshandiswa zvakanyanya muzvizoro uye zvigadzirwa zvekuchengeta munhu senge shampoos, lotions, uye makirimu seyakakora mumiriri uye inodzikamisa. Inobatsira kusimbisa chigadzirwa uye kuenderana.
Pharmaceuticals: Mukugadzirwa kwemishonga, HEC inoshanda sebhainda, firimu rekare, uye viscosity modifier mune mahwendefa ejasi, mafuta ekuzora, uye nemuromo kumiswa.
Kuvaka: HEC inoshandiswa mukuvaka zvinhu sependi, zvinonamira, uye dhaka kuvandudza kushanda, kunamatira, uye kuchengetedza mvura.
Indasitiri yeChikafu: HEC inowana zvikumbiro muindasitiri yechikafu seyakakora uye inodzikamisa muzvigadzirwa zvakaita sesosi, madhirezi, uye madhiri.
HEC Inonamira?
Iko kunamira kweHEC kunonyanya kuenderana nekuisa kwayo, magadzirirwo ayo anoshandiswa mukati, uye chaiyo mashandisiro. Mune chimiro chayo chakachena, HEC kazhinji hairatidzi kunamatira kwakakosha. Nekudaro, kana ichishandiswa muhuwandu hwepamusoro kana mumigadziriso ine zvimwe zvinonamira zvikamu, inogona kubatsira mukunamira kwese kwechigadzirwa.
Mukugadzira zvizorwa senge makirimu uye lotions, HEC inowanzosanganiswa nezvimwe zvinongedzo senge emollients uye humectants. Nepo HEC pachayo inogona kunge isiri yekunamira, izvi zvimwe zvikamu zvinogona kupesvedzera tactile zvimiro zvechigadzirwa chekupedzisira, zvinogona kutungamira kune inonamira sensation.
Saizvozvowo, mune zvigadzirwa zvekudya, HEC inowanzoshandiswa pamwe chete nezvimwe zvinhu. Zvichienderana nekugadzirisa uye kugadzirisa mamiriro, chimiro chekupedzisira uye kunamatira kwechigadzirwa kunogona kusiyana.
Hydroxyethyl cellulose (HEC) i polymer inoshanda zvakasiyana-siyana ine huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana siyana. Kunyangwe isiri yekunamira, kushandiswa kwayo mukuumbwa pamwe chete nezvimwe zvinongedzo dzimwe nguva kunogona kubatsira mukunamira muchigadzirwa chekupedzisira. Kunzwisisa zvivakwa uye maitiro ekugadzira akakodzera anogona kubatsira kudzikisira chero kusada kunamatira uye kushandisa mabhenefiti eHEC mukushandisa kwakasiyana.
