Xanthan chingamu uye Hydroxyethyl cellulose (HEC) ese ari mahydrocolloid anoshandiswa zvakanyanya mumaindasitiri akasiyana, kunyanya muchikafu, mishonga, uye zvigadzirwa zvekuchengeta munhu. Kunyangwe zvimwe zvakafanana mumashandisirwo azvo, akasiyana maererano nechimiro chavo chemakemikari, zvimiro, uye mashandiro.
1.Chemical Structure:
Xanthan chingamu: Iyo polysaccharide inotorwa kubva mukuviriswa kwemacarbohydrates, kunyanya glucose, nebhakitiriya Xanthomonas campestris. Iyo ine musana wemasara eglucose ane macheni eparutivi e trisaccharide anodzokorora mayunitsi, anosanganisira mannose, glucuronic acid, uye glucose.
HEC: Hydroxyethyl cellulose isiri-ionic cellulose ether yakabva kune cellulose, polysaccharide inowanzoitika inowanikwa mumiti yemadziro emadziro. HEC inogadziriswa nekuunza mapoka e-hydroxyethyl pane cellulose musana.
2.Solubility:
Xanthan gum: Inoratidza kunyungudika kwakanyanya mumvura inotonhora uye inopisa. Iyo inoumba yakanyanya viscous mhinduro kunyange panguva yakaderera.
HEC: Hydroxyethyl cellulose inonyungudika mumvura, uye kunyungudika kwayo kunogona kusiyana zvichienderana nehuwandu hwekutsiviwa (DS) yemapoka e-hydroxyethyl. Yepamusoro DS kazhinji inoguma mukunyungudika kuri nani.
3.Viscosity:
Xanthan chingamu: Iyo inozivikanwa nekusarudzika kwayo kukora zvivakwa. Kunyangwe pakudzika kwakadzika, xanthan chingamu inogona kuwedzera zvakanyanya viscosity yemhinduro.
HEC: Iyo viscosity yeHEC mhinduro zvakare inoenderana nezvinhu zvakaita sekutarisa, tembiricha, uye shear rate. Kazhinji, HEC inoratidza yakanaka thickening zvivakwa, asi viscosity yayo yakaderera kana ichienzaniswa nexanthan chingamu pane yakaenzana concentrations.
4.Shear Kuonda maitiro:
Xanthan chingamu: Mhinduro dze xanthan chingamu dzinowanzoratidza kuveura-kutetepa maitiro, zvichireva kuti viscosity yavo inodzikira pasi pekunetseka kweshear uye kupora kana kushushikana kwabviswa.
HEC: Saizvozvo, HEC mhinduro dzinoratidzawo shear-kuonda maitiro, kunyange chiyero chinogona kusiyana zvichienderana negiredhi chaiyo uye kugadzirisa mamiriro.
5.Kugarisana:
Xanthan gum: Inopindirana nehuwandu hwakawanda hwemamwe mahydrocolloids uye zvinwiwa zvinowanzoshandiswa mukudya uye kuchengetwa kwemunhu. Inogonawo kudzikamisa emulsions.
HEC: Hydroxyethyl cellulose inopindirana neyakasiyana siyana uye inogona kushandiswa pamwe chete nemamwe makobvu uye stabilizer kuti uwane inodiwa rheological properties.
6.Synergy nemamwe maThickeners:
Xanthan chingamu: Inoratidza synergistic mhedzisiro kana yakasanganiswa nemamwe mahydrocolloid akadai seguar gum kana mhashu bhinzi chingamu, zvichikonzera kuwedzera viscosity uye kugadzikana.
HEC: Saizvozvo, HEC inogona kuwiriranisa nemamwe makobvu uye mapolymers, ichipa kuita kwakasiyana-siyana mukugadzira zvigadzirwa zvine chaiwo magadzirirwo uye kuita zvinodiwa.
7. Nzvimbo dzekushandisa:
Xanthan chingamu: Inowana kushandiswa kwakakura muzvigadzirwa zvechikafu (semuenzaniso, sosi, marokwe, zvigadzirwa zvemukaka), zvigadzirwa zvekuchengeta munhu (semuenzaniso, mafuta ekuzora, makirimu, mushonga wemazino), uye zvigadzirwa zvemuindasitiri (semuenzaniso, zvinwiwa zvekuchera, pendi).
HEC: Hydroxyethyl cellulose inowanzoshandiswa muzvigadzirwa zvekuchengeta munhu (semuenzaniso, shampoos, kugeza muviri, mafuta), mishonga yemishonga (eg, ophthalmic solutions, oral suspensions), uye zvinhu zvekuvaka (semuenzaniso, pendi, adhesives).
8.Mutengo uye Kuwanikwa:
Xanthan chingamu: Inowanzo kudhura zvakanyanya kana ichienzaniswa neHEC, zvakanyanya nekuda kwekuvirisa kunobatanidzwa mukugadzirwa kwayo. Nekudaro, kushandiswa kwayo kwakapararira uye kuwanikwa kunobatsira pakugadzikana kwayo kwemusika.
HEC: Hydroxyethyl cellulose inodhura zvakanyanya kana ichienzaniswa nexanthan gum. Iyo inogadzirwa zvakanyanya kuburikidza nekemikari shanduko ye cellulose, iyo yakawanda muzvisikwa.
nepo xanthan gum neHEC vachigovana zvimwe zvakafanana mumashandisirwo avo sehydrocolloids, vanoratidza misiyano yakasiyana maererano nemakemikari avo, solubility, viscosity, shear-thinning maitiro, kuwirirana, synergy nemamwe makobvu, nzvimbo dzekushandisa, uye mutengo. Kunzwisisa misiyano iyi kwakakosha kune vanogadzira kuti vasarudze yakanyatsokodzera hydrocolloid kune chaiyo chigadzirwa maumbirwo uye inodiwa maitiro ekuita.
