Pesvedzero yedhigirii rekutsiva (DS) paHEC Hunhu

HEC (hydroxyethyl cellulose) isiri-ionic, mvura-inonyungudika polima iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana akadai sekuchengetedza munhu, mishonga, uye chikafu sechinhu chinokora, chinosunga, uye chinosimbisa.Iyo dhigirii yekutsiva (DS) yakakosha parameter iyo inogona kukanganisa zvakanyanya zvivakwa uye kuita kweHEC.

Iyo dhigirii yekutsiva inoreva huwandu hweavhareji yemapoka ehydroxyethyl akabatanidzwa kune yega yega anhydroglucose unit ye ​​cellulose musana.Mune mamwe mazwi, inoyera mwero weiyo cellulose molecule yakagadziridzwa nemapoka ehydroxyethyl.

Mhedzisiro yedhigirii yekutsiva pane HEC mhando yakakosha.Kazhinji, sezvo dhigirii yekutsiva inowedzera, solubility yeHEC mumvura inowedzera, uye viscosity yayo inoderera.HEC ine dhigirii yakakwirira yekutsiva ine yakaderera viscosity, uye inonyungudika mumvura.Izvi zvinodaro nekuti mapoka ehydroxyethyl anokanganisa kubatana kwehydrogen pakati pecheni dze cellulose, zvichitungamira kune yakavhurika uye inoshanduka chimiro.

Uyezve, dhigirii repamusoro rekutsiva rinogona kuvandudza kugadzikana kwekupisa kweHEC uye kuwedzera kuramba kwayo kune enzymatic degradation.Zvisinei, dhigirii yakanyanyisa yekutsiviwa inogona kukonzera kuderera kwehuremu hwema molecular uye kurasikirwa kwezvinhu zvepakutanga zvemusana we cellulose, izvo zvinogona kukanganisa kushanda kweHEC.

Muchidimbu, dhigirii yekutsiva ndiyo yakakosha parameter inogona kukanganisa zvakanyanya zvivakwa uye kuita kweHEC.Chiyero chepamusoro chekugadzirisa chinogona kuvandudza kugadzikana uye kugadzikana kwekushisa kweHEC, asi yakanyanyisa dhigirii yekutsinhanisa inogona kutungamirira pakurasikirwa kwezvinhu zvepakutanga zvemusana we cellulose, izvo zvinogona kukanganisa kushanda kweHEC.
