Zvenyama Zvimiro zveHydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) i polymer inonyungudika nemvura inotorwa kubva muselulosi. Inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kweiyo yakasarudzika yemuviri zvinhu. Zvimwe zvezvakakosha zvemuviri zvehydroxyethyl cellulose zvinosanganisira:

1. Solubility: HEC inonyungudika mumvura uye inoumba yakajeka, viscous mhinduro. Kunyungudika kweHEC kunogona kusiyana zvichienderana nezvinhu zvakaita sedhigirii rekutsinhanisa (DS) yemapoka ehydroxyethyl uye huremu hwepolymer.
2. Viscosity: HEC inoratidza yakakwira viscosity mumhinduro, iyo inogona kugadziridzwa nezvinhu zvakasiyana senge polymer concentration, tembiricha, uye shear rate. HEC mhinduro dzinowanzo shandiswa seyakakora maajenti mune dzakasiyana siyana maapplication, kusanganisira pendi, anonamira, uye zvigadzirwa zvekuchengeta munhu.
3. Firimu-Kugadzira Mano: HEC ine kugona kuumba anochinjika uye akabatana mafirimu pakuomeswa. Ichi chivakwa chinoshandiswa mumashandisirwo akadai semachira emapiritsi uye capsules mumishonga, pamwe mune zvekuzora uye zvigadzirwa zvekuchengeta munhu.
4. Kuchengeta Mvura: HEC ine yakanakisa yekuchengetedza mvura zvivakwa, zvichiita kuti ive inoshanda-inonyungudika mvura polima yekushandisa mukuvaka senge dhaka, grouts, uye renders. Inobatsira kudzivirira kurasikirwa kwemvura nokukurumidza panguva yekusanganiswa uye kushandiswa, kuvandudza kushanda uye kunamatira.
5. Thermal Stability: HEC inoratidza kugadzikana kwakanaka kwekushisa, kuchengetedza zvivakwa zvayo pamusoro pemhando dzakasiyana dzekushisa. Inogona kumira kupisa tembiricha inosangana mumaindasitiri akasiyana pasina kuderera kwakanyanya.
6. pH Kugadzikana: HEC yakagadzikana pamusoro pehupamhi pH renji, ichiita kuti ive yakakodzera kushandiswa mukuumbwa neacidic, neutral, kana alkaline mamiriro. Ichi chivakwa chinobvumira kushandiswa kwayo mune akasiyana maapplication pasina kunetsekana nezve pH-inoenderana nekuderedzwa.
7. Kugarisana: HEC inowirirana nehuwandu hwakawanda hwezvimwe zvinhu, zvinosanganisira munyu, acids, uye organic solvents. Kuenderana uku kunobvumira kugadzirwa kweakaomesesa masisitimu ane anoenderana zvivakwa mumaindasitiri akadai semishonga, kutarisirwa kwevanhu, uye kuvaka.
8. Biodegradability: HEC inotorwa kubva kune zvinogonekazve sosi sehuni pulp uye donje, zvichiita kuti ive biodegradable uye ine hushamwari. Inowanzo kufarirwa pamusoro pekugadzira mapolymer mumashandisirwo uko kusimudzira kuri kunetseka.

iyo yemuviri midziyo yehydroxyethyl cellulose (HEC) inoita kuti ive yekuwedzera yakakosha mumaindasitiri akasiyana-siyana, uko inobatsira pakuita, kugadzikana, uye kushanda kweakasiyana ezvigadzirwa uye magadzirirwo.
