Hydroxyethyl cellulose uye kushandiswa kwayo

Hydroxyethylcellulose (HEC) i polymer inonyungudika mumvura inotorwa kubva muselulosi, polima yemusikirwo inowanikwa muzvirimwa. Iyo inogadzirwa kuburikidza nekugadziriswa kwemakemikari ye cellulose, uko hydroxyethyl mapoka anounzwa pane cellulose musana. HEC ine kushandiswa kwakasiyana-siyana mumaindasitiri akasiyana nekuda kwezvakasiyana zvivakwa. Heano mamwe akajairika mashandisirwo ehydroxyethylcellulose:

1. Personal Care Zvigadzirwa: HEC inoshandiswa zvakanyanya muindasitiri yekutarisira munhu seanokora agent, stabilizer, uye firimu-former mune zvigadzirwa senge shampoos, conditioners, muviri washes, creams, lotions, uye gels. Inokwidziridza viscosity uye magadzirirwo ezvigadzirwa izvi, kuvandudza mashandiro avo uye hunhu hwekunzwa.
2. Paints uye Coatings: HEC inoshandiswa seyakakora uye rheology modifier mumapendi emvura, machira, uye zvinonamira. Inobatsira kudzora kuyerera kwezvimiro zvezviumbwa izvi, kuvandudza maitiro avo ekushandisa uye kuve nechokwadi chekuvhara yunifomu.
3. Pharmaceuticals: Muindasitiri yemishonga, HEC inoshandiswa sebhainda, firimu-former, uye viscosity enhancer mukugadzirwa kwehwendefa, ophthalmic solutions, topical creams, uye kumiswa kwemuromo. Inobatsira mukugadzirwa kwemapiritsi ane kuoma kwakafanana uye kuparara kwezvinhu uye inobatsira kuvandudza kugadzikana uye bioavailability yemishonga yemishonga.
4. Zvishandiso Zvekuvaka: HEC inowedzerwa kune zvigadzirwa zvekuvaka senge simende-based madhaka, mataira anonamira, uye grouts seanokora uye kuchengetedza mvura. Inovandudza kushanda uye kunamatira kwezvinhu izvi, kuwedzera kushanda kwavo uye kusimba.
5. Zvokudya Zvigadzirwa: Kunyange zvisingawanzowanzi, HEC inogona zvakare kushandiswa muzvigadzirwa zvechikafu seyakakora mumiriri uye inodzikamisa. Inobatsira kuvandudza magadzirirwo uye muromo wezvigadzirwa zvakaita sesosi, madhirezi, uye madhiri.
6. Maindasitiri Zvishandiso: HEC inowana manyorerwo muakasiyana maindasitiri maitiro, anosanganisira kugadzira mapepa, kudhinda machira, uye zvinwiwa zvekuchera. Iyo inoshanda seyakakora, yekumisa mumiriri, uye inodzivirira colloid mune izvi maapplication, zvichibatsira mukugadzirisa kushanda uye kunaka kwechigadzirwa.

Pakazere, hydroxyethylcellulose i polymer inoshanda zvakasiyana-siyana ine huwandu hwakasiyana hwekushandisa mumaindasitiri mazhinji. Kunyungudika kwayo kwemvura, kugona kukora, uye kuenderana nezvimwe zvinongedzo zvinoita kuti ive yekuwedzera yakakosha mune akawanda magadzirirwo uye zvigadzirwa.
