Ndeupi musiyano uripo pakati peHEC neHEMC?

HEC (Hydroxyethyl Cellulose) uye HEMC (Hydroxyethyl Methyl Cellulose) ese ari maviri mapolymers makomisheni anobva ku cellulose, polysaccharide inowanzoitika inowanikwa muzvirimwa.Ose ari maviri anoshandiswa seakobvu, anosimbisa, uye emulsifiers mune akasiyana zvigadzirwa, zvinosanganisira pendi uye coating, chikafu, mishonga, cosmetics, uye maindasitiri maapplication.

Musiyano mukuru pakati peHEC neHEMC uri mumakemikari avo.HEC isiri-ionic cellulose derivative, nepo HEMC iri ionic cellulose derivative.HEC inoumbwa neboka rimwechete re hydroxyethyl rakasungirirwa kumusana we cellulose, nepo HEMC inoumbwa nemapoka maviri e-hydroxyethyl akabatanidzwa kumusana we cellulose.

HEC ipolymer inonyungudika nemvura inoshandiswa seyakakora muzvigadzirwa zvakasiyana siyana, zvinosanganisira pendi & machira, chikafu, mishonga, uye zvekuzora.Inoshandiswa kuwedzera viscosity yechigadzirwa, kuvandudza kugadzikana kwayo, uye kupa hunyoro hunyoro.Inoshandiswawo se emulsifier kubatsira kuchengetedza zvimisikidzo kubva pakuparadzana.

HEMC zvakare iri mumvura-inonyungudika polima iyo inoshandiswa seyakakora mumiriri.Inoshandiswa mumhando dzakasiyana dzezvigadzirwa, zvinosanganisira kuvaka, chikafu, mishonga yemishonga, uye cosmetics.Inoshandiswa kuwedzera viscosity yechigadzirwa, kuvandudza kugadzikana kwayo, uye kupa hunyoro hunyoro.Inoshandiswawo se emulsifier kubatsira kuchengetedza zvimisikidzo kubva pakuparadzana.

HEC inonyanya kushandiswa mupendi nekugadzira zvigadzirwa, nepo HEMC ichinyanya kushandiswa mukuvaka uye zvizorwa.HEC inonyanya kushanda pakuwedzera viscosity yechigadzirwa kupfuura HEMC, uye zvakare yakagadzikana mune acidic uye alkaline mhinduro.HEMC inonyanya kushanda pakupa kugadzirwa kwakatsetseka kune chigadzirwa kupfuura HEC, uye zvakare yakagadzikana mukupisa kwakanyanya.

Muchidimbu, musiyano mukuru pakati peHEC neHEMC uri mumakemikari avo.HEC isiri-ionic cellulose derivative, nepo HEMC iri ionic cellulose derivative.HEC inonyanya kushandiswa mupende & machira, zvigadzirwa zvekugezesa, nepo HEMC ichinyanya kushandiswa mukuvaka uye zvekuzora.HEC inonyanya kushanda pakuwedzera viscosity yechigadzirwa, nepo HEMC inonyanya kushanda pakupa kugadzirwa kwakatsetseka.
