Hydroxyethyl cellulose: chii uye inoshandiswa kupi?

Hydroxyethyl cellulose (HEC) ipolmer inonyungudika nemvura inotorwa kubva muselulosi, yakasikwa polysaccharide inowanikwa mumadziro emiti. HEC inogadzirwa kuburikidza nekugadziriswa kwemakemikari ye cellulose, uko hydroxyethyl mapoka anounzwa pane cellulose musana. Uku kugadziridzwa kunowedzera kunyungudika kwemvura uye kushanda kwe cellulose, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa.

Heino tarisiro yehydroxyethyl cellulose uye mashandisiro ayo:

1. Thickening Agent: Imwe yemashandisirwo ekutanga eHEC seyakakora mumiriri mumaindasitiri akasiyana. Inowanzo shandiswa mupendi, machira, zvinonamira, uye kudhinda ingi kuwedzera viscosity uye kunatsiridza kuenderana kwekuumbwa. Muzvigadzirwa zvekuchengeta zvemunhu zvakaita seshamposi, maconditioners, lotions, uye makirimu, HEC inoshanda seyakakora yekusimudzira magadzirirwo uye kugadzikana kwechigadzirwa.
2. Stabilizer: HEC inoshanda seyakagadzikana mune emulsion masisitimu, kudzivirira kuparadzaniswa kwechikamu uye kuchengetedza yunifomu kupararira kwezvigadzirwa. Inowanzowedzerwa kune cosmetic uye mishonga yekugadzira mishonga yekuvandudza kugadzikana kwavo uye hupenyu hwesherufu.
3. Firimu Yaimbove: HEC ine firimu-inogadzira zvivakwa zvinoita kuti ive yakakosha mumashandisirwo akasiyana siyana. Muindasitiri yekuvaka, inowedzerwa kune simende-yakavakirwa zvinhu kuvandudza kushanda uye kusimudzira kunamatira kwekupotera. Muzvigadzirwa zvekutarisira zvemunhu, HEC inoumba firimu rakatetepa paganda kana bvudzi, ichipa chipingamupinyi chekudzivirira uye kuwedzera hunyoro kuchengetedza.
4. Binder: Mukugadzirwa kwehwendefa, HEC inoshandiswa sebhainda kuti ibate zvinhu zvinoshanda pamwe chete uye ive nechokwadi chehutano hwehutano hwemapiritsi. Inobatsira kuvandudza kusungirirwa kwehupfu musanganiswa uye inobatsira kuumbwa kwemapiritsi eunifomu nekuoma kwakafanana uye kuparara kwezvinhu.
5. Suspension Agent: HEC inoshandiswa semumiriri wekumisa mumisikidzo yemishonga uye oral liquid formulations. Inobatsira kudzivirira kugadziriswa kwezvimedu zvakasimba uye inochengetedza yunifomu kugoverwa kwezvinhu zvinoshanda mukati mekugadzirisa.

Pakazere, hydroxyethyl cellulose i polymer inoshanda zvakasiyana-siyana ine huwandu hwakasiyana hwemaindasitiri nekutengesa maapplication. Kunyungudika kwayo kwemvura, kugona kukora, uye kugadzira bhaisikopo kunoita kuti ive chinhu chakakosha muzvigadzirwa zvakasiyana mumaindasitiri akasiyana.
