Ndeupi musiyano uripo pakati peHEC neCMC?

HEC neCMC imhando mbiri dze cellulose ether, polysaccharide inowanikwa mumiti uye inoshandiswa mumhando dzakasiyana dzezvigadzirwa. Nepo ese ari maviri akatorwa kubva ku cellulose, ane akasiyana zvivakwa uye mashandisirwo.

HEC, kana kuti hydroxyethyl cellulose, isiri-ionic, mvura-inonyungudika polima inobva muselulosi. Inoshandiswa seyakakora mumiriri, emulsifier, stabilizer, uye inomisa mumiriri mune zvakasiyana zvigadzirwa, zvinosanganisira zvekuzora, mishonga, uye zvigadzirwa zvekudya. HEC inoshandiswawo kuwedzera viscosity yeaqueous solutions uye kugadzirisa magadzirirwo ezvigadzirwa. Inoshandiswawo mukugadzira mapepa, pendi, uye zvinonamira.

CMC, kana carboxymethyl cellulose, i polymer inonyungudika nemvura inotorwa kubva muselulosi. Inoshandiswa seyakakora mumiriri, emulsifier, stabilizer, uye inomisa mumiriri mune zvakasiyana zvigadzirwa, zvinosanganisira zvekuzora, mishonga, uye zvigadzirwa zvekudya. CMC inoshandiswawo kuwedzera viscosity yeaqueous mhinduro uye kuvandudza magadzirirwo ezvigadzirwa. Inoshandiswawo mukugadzira mapepa, pendi, uye zvinonamira.

Musiyano mukuru pakati peHEC neCMC uri muchimiro chavo chemakemikari. HEC isiri-ionic polymer, zvichireva kuti haina chero mhosva ine chekuita nayo. CMC, kune rumwe rutivi, ionic polymer, zvichireva kuti ine mhosva isina kunaka yakabatana nayo. Uyu mutsauko mukuchaira unokanganisa nzira iyo maviri mapolymer anodyidzana nemamwe mamorekuru, uye nekudaro anokanganisa zvimiro zvavo nemashandisirwo.

HEC inonyanya kunyungudika mumvura kupfuura CMC, uye inoshanda zvakanyanya seyakakora mumiriri. Iyo zvakare yakanyanya kugadzikana mune acidic uye alkaline mhinduro, uye inonyanya kurwisa kupisa uye chiedza. HEC zvakare inopokana nehutachiona hwehutachiona, zvichiita kuti ive sarudzo iri nani kune zvigadzirwa zvinoda hupenyu hurefu hwesherufu.

CMC haina kunyungudika mumvura kupfuura HEC, uye hainyanyi kushanda sechinhu chakakora. Iyo zvakare haina kugadzikana mune acidic uye alkaline mhinduro, uye haina kurwisa kupisa uye chiedza. CMC zvakare inotapukirwa nekushatiswa kwehutachiona, zvichiita kuti ive sarudzo isina kukodzera kune zvigadzirwa zvinoda hupenyu hurefu hwesherufu.

Mukupedzisa, HEC neCMC imhando mbiri dze cellulose ether ine zvivakwa zvakasiyana uye mashandisirwo. HEC inonyanya kunyungudika mumvura uye inoshanda zvakanyanya seyakakora mumiriri, nepo CMC isinganyanyi kunyungudika mumvura uye isinganyanyi kushanda seyakakora. HEC zvakare yakanyanya kugadzikana mune acidic uye alkaline mhinduro, uye inopesana nekupisa uye chiedza. CMC haina kugadzikana mune acidic uye alkaline mhinduro, uye haina kusimba nekupisa nechiedza. Ose mapolymer ane akasiyana ekushandisa mukugadzira zvizorwa, mishonga, zvigadzirwa zvekudya, bepa, pendi, uye zvinonamira.
