| Advantages︰ | Xanthan Gum is a kind of white-like or light yellow powder.It is a biological gum with unique properties,such as adhesion,suspendation,emulsion,stabilize.Xanthan Gum has no smell,no poisonous,and it can be completely dissolved in water,Xanthan molecule present polyanionic features in the water solution,have a special physical-chemical properties :
¡¡¡¡1. High viscosity : high viscosity at low concentration,it is a high efficient adhere agent.
¡¡¡¡2. Shear strength(pseudoplasticity) : the solution of¡¡Xanthan Gum has a high viscosity on still or low shear strength condition,the viscosity will be lower when the shear is high,but the structure of the molecular is not change.when the shear lose,the viscosity come back.
¡¡¡¡3. Thermal stable:the properties are basically the same at large therm area between -18¡æ and 120¡æ.
¡¡¡¡4. Tolerance to salt : on condition of¡¡high salt strength ,and even on condition of saturated brine, the solubility belongs to it.there's no influence to viscosity.
¡¡¡¡5. Tolerance to acid, alkaline : viscosity of the solution are stable between PH 1 and 12.
¡¡¡¡6. Compatiblity : high comptability when acid,alkaline,salt,bacteriacide,natural or synthetic exist in the same system.The viscosity will increase when mixed with guar gum or locust gum.
¡¡¡¡7. Tolerance to oxidant and enzymetic decomposition : xanthan gum's stable structure of dual helical have tolerance to oxidant and enzymetic decomposition.
¡¡¡¡8. Suspensing ability : good to suspending solids and oil droplets.
¡¡¡¡Because of the above unique properties of Xanthan Gum,it has a extensive application in food processing, pesticide,household chemicals,paper-making,textile printing,fire-fighting,oil recovery and many other fields. |
