Kusiyana pakati peSodium CMC, Xanthan Gum uye Guar Gum

Sodium carboxymethyl cellulose (CMC), xanthan chingamu, uye guar chingamu ese anoshandiswa zvakanyanya hydrocolloids ane akasiyana maapplication muzvikamu zvekudya, zvemishonga, zvekuzora, uye maindasitiri. Kunyange ivo vachigovana zvimwe zvakafanana maererano nekukora, kudzikamisa, uye gelling zvivakwa, kune zvakare mutsauko unocherechedzwa mumakemikari zvimiro, masosi, mashandiro, uye mashandisirwo. Ngationgororei misiyano pakati peaya matatu hydrocolloids:

1. Kuumbwa Kwemakemikari:

• Sodium Carboxymethyl Cellulose (CMC): CMC inonyungudika mumvura kubva kune cellulose, iyo polysaccharide inoumbwa nekudzokorora zvikamu zveglucose. Mapoka eCarboxymethyl (-CH2-COOH) anounzwa pane cellulose musana kuburikidza ne etherification reactions, ichipa kunyungudika kwemvura uye inoshanda zvivakwa kune polymer.
• Xanthan Gum: Xanthan chingamu imicrobial polysaccharide inogadzirwa kuburikidza nekuviriswa nebhakitiriya Xanthomonas campestris. Inosanganisira kudzokorora zvikamu zveglucose, mannose, uye glucuronic acid, ine cheni dzomumativi dzine mannose uye glucuronic acid residues. Xanthan chingamu inozivikanwa nehuremu hwayo hwemamorekuru uye yakasarudzika rheological properties.
• Guar gum: Guar gum inotorwa kubva kumagumo eguar bean (Cyamopsis tetragonoloba). Iyo inoumbwa negalactomannan, polysaccharide inoumbwa nemutsara cheni yemannose units ine galactose parutivi cheni. Guar gum ine huremu hwemamorekuru uye inoumba zvigadziriso zve viscous kana hydrated.

2. Kwakabva:

• CMC inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro.
• Xanthan chingamu inogadzirwa kuburikidza nekuvirisa hutachiona hwemakhahydrates neXanthomonas campestris.
• Guar gum inowanikwa kubva ku endosperm yeguar bean.

3. Mabasa:

• Sodium Carboxymethyl Cellulose (CMC):
  • Inoshanda seyakakora, stabilizer, binder, uye firimu-former mune akasiyana maapplication.
  • Inogadzira sparent uye thermally reversible gels.
  • Inoratidza pseudoplastic kuyerera maitiro.
• Xanthan Gum:
  • Inoshanda seyakakora, stabilizer, emulsifier, uye inomisa mumiririri.
  • Inopa yakanakisa viscosity control uye shear-kuonda maitiro.
  • Inogadzira zvigadziriso zve viscous uye gel dzakagadzikana.
• Guar Gum:
  • Inoshanda seyakakora, stabilizer, binder, uye emulsifier.
  • Inopa yakakwira viscosity uye pseudoplastic kuyerera maitiro.
  • Inogadzira zvigadziriso zve viscous uye gel dzakagadzikana.

4. Solubility:

• CMC inonyungudika zvakanyanya mumvura inotonhora uye inopisa, ichigadzira yakajeka uye viscous mhinduro.
• Xanthan chingamu inonyungudika mumvura inotonhora uye inopisa, ine yakanakisa dispersibility uye hydration zvivakwa.
• Guar gum inoratidza kushomeka kwekunyungudika mumvura inotonhora asi inopararira zvakanaka mumvura inopisa kugadzira zvigadziriso zve viscous.

5. Kugadzikana:

• CMC mhinduro dzakagadzikana pamusoro pehupamhi hwepH uye tembiricha mamiriro.
• Xanthan chingamu mhinduro dzakagadzikana pamusoro pehupamhi pH renji uye inoshingirira kupisa, kugera, uye electrolytes.
• Guar gum mhinduro dzinogona kuratidza kudzikama kwakadzikira pane yakaderera pH kana pamberi peiyo yakanyanya kuwanda yemunyu kana calcium ions.

6. Zvikumbiro:

• Sodium Carboxymethyl Cellulose (CMC): Inoshandiswa muzvigadzirwa zvechikafu (semuenzaniso, masosi, madhirezi, bhekari), mishonga (semuenzaniso, mapiritsi, suspensions), zvizoro (semuenzaniso, makirimu, lotions), machira, uye maindasitiri maapplication (semuenzaniso, mapepa, detergents). )
• Xanthan Gum: Inoshandiswa zvakanyanya muzvigadzirwa zvechikafu (semuenzaniso, masaradhi madhirezi, sosi, mukaka), mishonga (semuenzaniso, kumiswa, kuchengetwa kwemuromo), zvizorwa (semuenzaniso, mafuta, mushonga wemazino), zvinwiwa zvekuchera mafuta, uye zvimwe zvinoshandiswa mumaindasitiri.
• Guar Gum: Inoshandiswa muzvigadzirwa zvechikafu (semuenzaniso, zvakabikwa, mukaka, zvinwiwa), mishonga (semuenzaniso, mahwendefa, kumiswa), zvizorwa (semuenzaniso, makirimu, mafuta ekuzora), kudhinda machira, uye zvinwiwa zvehydraulic fracturing muindasitiri yeoiri.

Mhedziso:

Nepo sodium carboxymethyl cellulose (CMC), xanthan gum, uye guar gum vachigovana zvimwe zvakafanana mukushanda kwavo uye mashandisirwo sehydrocolloids, ivo vanoratidzawo mutsauko wakasiyana mumakemikari avo, masosi, zvivakwa, uye mashandisiro. Kunzwisisa misiyano iyi kwakakosha pakusarudza iyo yakanyanya kukodzera hydrocolloid kune chaiyo mashandisirwo mumaindasitiri akasiyana. Imwe neimwe hydrocolloid inopa yakasarudzika mabhenefiti uye maitiro ekuita ayo anogona kugadzirwa kuti asangane nezvinodiwa zveakasiyana mafomati uye maitiro.
