Chii chinonzi Hydroxyethyl Cellulose?

Hydroxyethyl cellulose ichena kusvika kuchiedza yero fibrous kana powdery solid, isiri-chepfu, isingaravike, uye inonyungudika zviri nyore mumvura. Haina kunyungudika mune zvakajairika organic solvents. Iyo ine zvimiro zvekukora, kumisa, kubatana, emulsifying, kuparadzira, uye kuchengetedza unyoro. Mhinduro dzine akasiyana viscosity siyana dzinogona kugadzirirwa. Iine yakasarudzika yakanaka munyu solubility mu electrolytes. Hydroxyethyl cellulose ivhu jena kana rakareruka yero isinganhuhwi, isinganakidze, uye iri nyore kuyerera. Inonyungudika mumvura inotonhora uye inopisa, uye kazhinji isinganyunguriki mune zvakawanda organic solvents. Iyo viscosity inochinja zvishoma kana iyo pH kukosha iri muhuwandu hwe2-12, asi viscosity inoderera kupfuura iyi chiyero.

Application

1. Hydroxyethyl cellulose (HEC) inonzi non-ionic soluble cellulose ether ine yakanaka thickening, kumiswa, kupararira, emulsification, adhesion, kuumbwa kwefirimu, kudzivirira unyoro uye inodzivirira colloid properties. Nekuda kwekusiyana kwayo kwemuviri uye makemikari zvimiro, HEC inoshandiswa zvakanyanya muminda yakawanda, kusanganisira asi isina kuganhurirwa kubviswa kwemafuta, machira, kuvaka, chikafu chemishonga, machira, kugadzira mapepa uye polymerization.
2. Mumunda wemishonga, kunze kwekuita thickener uye kudzivirira, hydroxyethyl cellulose inewo migumisiro yekunyorova, hydrating, anti-aging, kuchenesa ganda, uye kubvisa melanin. Inokodzera kugadzira madonhwe emeso, masprays emhino, mhinduro dzemumuromo, etc. Inogona kuwedzera viscosity yemushonga, kuvandudza kunyudzwa kwemushonga mumuviri, uye kuwedzera kugadzikana kwemushonga kudzivirira kuparara kwezvinodhaka uye oxidation.
3. Muindasitiri yezvizoro, HEC inoshandiswa zvakanyanya mukugadzirwa kwe shampoo, conditioner, cream, lotion nezvimwe zvigadzirwa. Inogona kugadzirisa viscosity uye magadzirirwo ezvizoro kuti zvive nyore kuisa uye kutora. Panguva imwecheteyo, inewo maitiro ekunyorovesa, anogona kuvhara munyoro, uye kudzivirira kuoma kweganda uye kuputika.
4. Mukuwedzera, hydroxyethyl cellulose inonyanya kushandiswa seyakasviba, ruvara uye inochengetedza mumhizha yezvokudya, iyo inogona kuwedzera viscosity nekugadzirwa kwezvokudya uye kuvandudza kunaka uye kunaka kwezvokudya. Inogona zvakare kushandiswa se emulsifier uye stabilizer kudzivirira chikafu stratification uye kunaya.
5. Nezve acidity uye alkalinity yehydroxyethyl cellulose, sezvo iri ye-non-ionic cellulose ether class, haisi acidic kana alkaline. Yayo kemikari formula ndeye (C2H6O2) n, ine yakanaka solubility, kugadzikana uye thickening zvivakwa, uye inoita basa rakakosha mune dzakasiyana siyana dzekushandisa.
