Ko hydroxyethylcellulose inonamira here?

Hydroxyethylcellulose (HEC)i polymer inowanzo shandiswa mumaindasitiri akasiyana siyana, kusanganisira emishonga, zvekuzora, uye chikafu. Hunhu hwayo hunogona kusiyana zvichienderana nezvinhu zvakaita sekutarisa, uremu hwema molecular, uye kuvapo kwezvimwe zvinongedzo. Nepo HEC pachayo isiri yekunamira, kugona kwayo kugadzira gels kana zvigadziriso zvinogona kuguma nekunamira kwemavara pasi pemamwe mamiriro.

HEC isiri-ionic mvura-soluble polymer inotorwa kubva ku cellulose. Basa rayo rekutanga rakaita seyakakora mumiriri, stabilizer, kana firimu-yekare mune zvigadzirwa kubva kune zvekuchengeta zvinhu senge shampoos uye lotions kusvika kumishonga yekugadzira uye zvigadzirwa zvekudya. Yayo mamorekuru chimiro inoita kuti iwirirane nemamorekuru emvura, ichigadzira hydrogen zvisungo uye kugadzira viscous mhinduro kana gels.

Iko kunamira kweHEC-ine zvigadzirwa kunogona kukanganiswa nezvinhu zvakati wandei:

Concentration: Kukwirira kwepamusoro kweHEC mukugadzirisa kunogona kukonzera kuwedzera viscosity uye zvinogona kunamatira maumbirwo. Maformulators anonyatso gadzirisa kusungirirwa kweHEC kuti uwane iyo inodiwa kuenderana pasina kuita kuti chigadzirwa chinyanye kunamira.
Kudyidzana nezvimwe zvinhu:HECinogona kupindirana nezvimwe zvikamu mukuumbwa, senge surfactants kana munyu, izvo zvinogona kushandura rheological properties. Zvichienderana nekugadzirwa kwacho, kupindirana uku kunogona kubatsira mukunamira.
Mamiriro ekunze: Zvinhu zvakaita setembiricha uye hunyoro zvinogona kukanganisa maitiro eHEC-ine zvigadzirwa. Munzvimbo dzine hunyoro, semuenzaniso, HEC gels inogona kuchengetedza hunyoro kubva kumhepo, zvichigona kuwedzera kunamira.
Maitiro ekushandisa: Iyo nzira yekushandisa inogona zvakare kukanganisa maonero ekunamira. Semuyenzaniso, chigadzirwa chine HEC chinogona kunzwa kushoma zvishoma kana chikaiswa zvakaenzana, asi kana chigadzirwa chakawandisa chikasara paganda kana bvudzi, chinogona kunzwa chakashata.
Molecular uremu: Iyo molecular huremu hweHEC inogona kukanganisa kugona kwayo kukora uye magadzirirwo echigadzirwa chekupedzisira. Yakakwira molecular uremu HEC inogona kukonzera mamwe maviscous mhinduro, ayo anogona kubatsira mukunamira.
Mukugadzira zvizorwa, HEC inowanzo shandiswa kupa yakatsetseka, ine cream mavara kune lotions uye makirimu pasina kusiya inonamira yakasara. Nekudaro, kana isina kunyatsogadzirwa kana kuiswa, zvigadzirwa zvine HEC zvinogona kunzwa tacky kana kunamira paganda kana bvudzi.

apohydroxyethyl cellulosepachayo haina kunamatira, kushandiswa kwayo mukuumbwa kunogona kukonzera zvigadzirwa zvine madhigirii akasiyana ekunamira zvichienderana nekugadzira zvinhu uye nzira dzekushandisa. Maformulators anonyatso enzanisa zvinhu izvi kuti uwane inodiwa manyorerwo uye kuita mune yekupedzisira chigadzirwa.
