Ndiani mugadziri wehydroxyethylcellulose?

Hydroxyethylcellulose (HEC) i polymer yekugadzira iyo inoshandiswa mumaindasitiri akasiyana siyana nezvinangwa zvakasiyana. Iyo isiri-ionic, mvura-inonyungudika polymer iyo inotorwa kubva muselulosi, uye inoshandiswa seyakakora mumiriri, emulsifier, stabilizer, uye suspending agent.

HEC inogadzirwa nemakambani akasiyana-siyana, anosanganisira Dow Chemical, BASF, Ashland, AkzoNobel, uye Clariant. Dow Chemical ndeimwe yevagadziri vakakura veHEC, uye inogadzira akasiyana mamakisi eHEC, kusanganisira iyo Dowfax neNatrosol brand. BASF inogadzira Cellosize brand yeHEC, uku Ashland ichigadzira iyo Aqualon brand. AkzoNobel inogadzira mhando dzeAqualon neAquasol dzeHEC, uye Clariant inogadzira mhando yeMowiol.

Imwe neimwe yemakambani aya inogadzira akasiyana mamakisi eHEC, ayo anosiyana maererano nehuremu hwemamorekuru, viscosity, uye zvimwe zvivakwa. Iyo molecular uremu hweHEC inogona kubva ku100,000 kusvika ku1,000,000, uye viscosity inogona kubva ku1 kusvika ku10,000 cps. Iwo mamakisi eHEC anogadzirwa nekambani yega yega anosiyanawo maererano nekunyungudika kwavo, kugadzikana, uye kuenderana nezvimwe zvinongedzo.

Pamusoro pevagadziri vakuru veHEC, kune zvakare akati wandei emakambani madiki anogadzira HEC. Aya makambani anosanganisira Lubrizol, uyeKima Chemical. Imwe neimwe yemakambani aya inoburitsa akasiyana mamakisi eHEC, ayo akasiyana maererano nemidziyo yavo.

Pakazara, kune makambani akasiyana-siyana anogadzira HEC, uye kambani imwe neimwe inoburitsa magiredhi akasiyana eHEC. Iwo mamakisi eHEC anogadzirwa nekambani yega yega anosiyana maererano nehuremu hwavo hwemamorekuru, viscosity, solubility, kugadzikana, uye kuenderana nezvimwe zvinongedzo.
