Thickener hec hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ndeye nonionic cellulose inobuda iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kwekukora kwayo, kumisa, uye emulsifying zvivakwa. HEC ipolymer inonyungudika mumvura inogona kunyungudutswa nyore mumvura inotonhora kuita mhinduro dzakajeka uye dzisina ruvara. HEC inowanzoshandiswa seyakasvibirira mune zvakasiyana-siyana zvekushandisa, kusanganisira majasi, zvinonamira, zvigadzirwa zvekuchengeta munhu, uye mishonga yemishonga.

HEC inogadzirwa nekugadzirisa natural cellulose, polymer ine glucose units yakabatanidzwa pamwe chete ne β (1 → 4) glycosidic bonds. Kugadziriswa kwe cellulose kunosanganisira kuunza mapoka ehydroxyethyl (-CH2CH2OH) pazvikamu zveanhydroglucose zvemusana we cellulose. Kugadziriswa uku kunoguma mumvura-inonyungudika polima inogona kuumba hydrogen zvisungo nemamorekuru emvura, zvichiita kuti paumbwe mhinduro ye viscous.

HEC inobudirira thickener nekuda kwekukwanisa kwayo kugadzira gel-yakafanana chimiro kana ichiwedzerwa kune mhinduro. Mapoka ehydroxyethyl ari paHEC molecule anogona kudyidzana nemamorekuru emvura, zvichikonzera kuumbwa kwehydrogen bond. Iyo hydrogen zvisungo pakati peHEC molecule uye mamorekuru emvura anoita kuti HEC molecule ive hydrated uye iwedzere muhukuru. Sezvo HEC molecule inowedzera, inoumba hutatu-dimensional network inobata mvura uye zvimwe zvikamu zvakanyungudutswa, zvichiita kuti kuwedzera kwe viscosity yemhinduro.

Iko kugona kwekukora kweHEC kunokanganiswa nezvinhu zvakasiyana, kusanganisira kuwanda kweHEC mumhinduro, tembiricha, uye pH. Kuwedzera kwepamusoro kweHEC mumhinduro kunotungamirira kune kuwedzera kwakakosha kwe viscosity. Zvisinei, kuwedzera kuwanda kweHEC kupfuura imwe nzvimbo kunogona kukonzera kuderera kweviscosity nekuda kwekuumbwa kwezvikamu. Iyo tembiricha inokanganisawo kugona kwekukora kweHEC, ine tembiricha yepamusoro inotungamira mukudzikira kweviscosity. Iyo pH yemushonga inogonawo kukanganisa kugona kwekukora kweHEC, ine yakakwira pH tsika inotungamira mukudzikira kweviscosity.

HEC inowanzo shandiswa seyakakora mumashandisirwo akasiyana siyana, kusanganisira machira uye pendi. Mukuputira, HEC inowedzerwa kune kugadzirwa kwekuvandudza rheological properties yekuputira. Rheological properties ye coating inoreva kugona kuyerera nekudzika pamusoro. HEC inogona kuvandudza kuyerera uye kuyera zvivakwa zvejasi nekuwedzera viscosity yayo uye kuderedza maitiro ayo ekudonha. HEC inogonawo kuvandudza kugadzikana kwejasi nekudzivirira kugadzika kwe pigment uye zvimwe zvinyoro.

Mune zvinonamira, HEC inoshandiswa seyakakora yekuvandudza viscosity uye tackiness yekunamatira. Iyo viscosity yekunamatira yakakosha pakukwanisa kwayo kunamatira kumusoro uye kugara panzvimbo. HEC inogona kuvandudza viscosity yekunamatira uye kudzivirira kubva pakudonha kana kumhanya. HEC inogonawo kuvandudza tackiness yekunamatira, ichibvumira kuti inamate zviri nani kune pamusoro.

Muzvigadzirwa zvekuchengetedza munhu, HEC inoshandiswa seyakakora uye inodzikamisa. HEC inowanzoshandiswa mumashampoos, maconditioners, uye kugezeswa kwemuviri kuvandudza viscosity yavo uye magadzirirwo. HEC inogonawo kuvandudza kugadzikana kwezvigadzirwa izvi nekudzivirira kupatsanurwa kwechikamu uye kugadzirisa kwezvakaoma.

Mumishonga, HEC inoshandiswa seyakakora uye inomisa mumiriri. HEC inowanzoshandiswa mumuromo kumiswa kumisa zvinodhaka zvisinganyunguriki mune yemvura svikiro. HEC inogona zvakare kushandiswa seyakakora mune topical creams uye gels kuvandudza viscosity yavo uye magadzirirwo.

Mukupedzisa, HEC ipolymer inonyungudika mumvura inoshandiswa zvakanyanya seyakakora mumaindasitiri akasiyana nekuda kwekunaka kwayo kukora, kumisa, uye emulsifying zvivakwa.
