Chii chinonzi sodium carboxymethyl cellulose?

Sodium carboxymethyl cellulose (CMC) inonyungudika nemvura kubva kune cellulose, inova polysaccharide inowanzoitika inowanikwa mumadziro ezvidyarwa. CMC inogadzirwa kuburikidza nekugadziriswa kwemakemikari ye cellulose, uko carboxymethyl mapoka (-CH2COONa) anounzwa pane cellulose musana.

Kuunzwa kwemapoka ecarboxymethyl kunopa akati wandei akakosha zvivakwa kune cellulose, zvichiita kuti CMC ive yekuwedzera uye yakakosha mukuwedzera mumaindasitiri akasiyana, kusanganisira chikafu, mishonga yemishonga, zvizorwa, kutarisirwa kwevanhu, machira, uye maindasitiri ekushandisa. Zvimwe zvezvinhu zvakakosha uye mabasa e sodium carboxymethyl cellulose anosanganisira:

1. Kunyungudika kweMvura: CMC inonyungudika zvakanyanya mumvura, ichigadzira mhinduro dzakajeka, dze viscous. Ichi chivakwa chinobvumira kubata nyore uye kuisirwa mune aqueous masisitimu akadai sezvigadzirwa zvechikafu, mishonga yemishonga, uye magadzirirwo ekuchengetedza ega.
2. Kukora: CMC inoita seyakakora mumiriri, ichiwedzera viscosity yemhinduro uye kumiswa. Inobatsira kupa muviri uye magadzirirwo kune zvigadzirwa zvakaita sesosi, madhirezi, makirimu, uye lotions.
3. Kudzikamisa: CMC inoshanda seyakagadzikana nekudzivirira kuunganidzwa uye kugadzirisa zvimedu kana madonhwe mukumiswa kana emulsions. Inobatsira kuchengetedza yunifomu kupararira kwezvigadzirwa uye inodzivirira kuparadzaniswa kwechikamu panguva yekuchengetedza nekubata.
4. Kuchengeta Mvura: CMC ine yakanakisa kuchengetedza mvura, ichiibvumira kutora uye kubatirira pamvura zhinji. Ichi chivakwa chinobatsira mukushandisa uko kuchengetedza hunyoro kwakakosha, senge muzvinhu zvakabikwa, confectionery, uye zvigadzirwa zvekuchengeta munhu.
5. Kugadzira Firimu: CMC inogona kuumba akajeka, anochinjika mafirimu kana akaomeswa, achipa zvipingamupinyi zvivakwa uye kuchengetedzwa kwemwando. Inoshandiswa mukuvhara, zvinonamira, uye mahwendefa emishonga kugadzira mafirimu ekudzivirira uye machira.
6. Kusunga: CMC inoita sebhainda nekugadzira zvisungo zvekunamira pakati pezvidimbu kana zvikamu mumusanganiswa. Inoshandiswa mumapiritsi emishonga, ceramics, uye mamwe magadzirirwo akasimba ekuvandudza kubatana uye kuoma kwehwendefa.
7. Rheology Kugadziriswa: CMC inogona kugadzirisa rheological zvimiro zvemhinduro, zvichikanganisa mafambiro ekuyerera, viscosity, uye shear-kutetepa maitiro. Inoshandiswa kudzora kuyerera uye magadzirirwo ezvigadzirwa zvakaita sependi, ingi, uye zvinwiwa zvekuchera.

sodium carboxymethyl cellulose ndeye multifunctional additive ine dzakasiyana siyana dzekushandisa mumaindasitiri akasiyana siyana. Kuita kwayo kwakasiyana-siyana, kunyungudika kwemvura, kukora, kudzikamisa, kuchengetedza mvura, kugadzira firimu, kusunga, uye rheology-kugadzirisa zvivakwa zvinoita kuti ive chinhu chakakosha muzvigadzirwa zvisingaverengeki uye magadzirirwo.
