CHARACTERISTICS:
The most important property of Guar Gum is its ability to hydrate rapidly in cold water, to attain a very high viscosity at relatively low concentrations. Its specific colloidal nature gives the solution an excellent thickening power which is 6 to 10 times higher than that obtained from starch. It is stable over a wide range of pH. It also improves flowability and pumpability of fluid. It is a superior friction loss reducing agent.
Guar Gum, either modified or unmodified, is a very versatile and efficient bio-polymer covering a wide range of industrial applications such as:
Oil drilling
Textile printing
Human Food and Pet Food
Paper
Explosive
Water Treatment
Ore flotation
where its binding, thickening, film forming and lubricating factors are of great interest.
In paper industry, Guar Gum ensures a more regular distribution of pulp fibre throughout the sheet resulting in increased burst strength and tensile strength. High recovery of purified ore is achieved when it is used as depressant for slimes.
For food applications, Guar Gum is an effective water retention agent because it is intensely hydrophilic. It is widely used to thicken and stabilise salad dressings, ice-cream, lollipops, bakery products, confectioneries, meat, sausages and cheese spread. It is also used as a stabiliser in frozen food.
In textile industry, it is used as a thickening and sizing agent. It is used as thickening agent in various pharmaceutical preparations. Guar Gum is also used in various cosmetics in the manufacture of both toothpaste and shaving creams. It imparts slip for extruding the paste from the tube without applying excessive pressure. It mixes well with most detergent systems and hence is used in the manufacture of shampoos and cleansers.
Besides the above uses, Guar Gum is also used in ceramics, tobacco industry and in the manufacture of water-proofing agent in explosive.
THE MAIN APPLICATION OF THE ABOVE DERIVATES ARE AS FOLLOWS:
1) Hydroxy-alkylated guar gum are the derivatives which have attracted the maximum applications of guar gum. In the paper industry, formation of derivatives results in a decrease in the extent of hydrogen bonds formed with cellulose, which is useful for production of certain special grades of paper. In the mineral industry, they are used as filtration aids in the treatment of uranium minerals. In the explosive industry, solubility in glycols and alcohol make these derivatives interesting as thickness for production of certain types of explosives.
2) Hydroxypropyl guar may be deploymerized at controlled rates, using a compound such as ammonium persulfate. This technique is used in oil stimulation where viscosity of guar is used for fracturing and must be reduced afterwards through depolymerisation of the gum in order to enable pumping out of the oil.
3)The carboxymethyl guar gives better results than guar gum in textiles and carpet printing.
4) Modified guar gum is also used in textile industry.
5) The oxidised guar gum is insoluble in water. It can be used as a wet-end paper additive.
6) Acetates of guar gum can be used to make films.
7) Cationic guar, being a highly active flocculant, can be used in mineral dressing and waste water treatment. It hydrates more quickly and is less acid or alkali sensitive than unmodified guar. It acts as a better flocculant for iron, copper and zinc ores. It imparts dry strength to paper. It is also useful for fibre retention and as a de-watering aid in sheet formation.
8) Sulphated guar gum can be used as a substitute of heparin to prevent coagulation of blood.
9) Guar gum formate is superior to modified guar gum as a sizing agent in the paper industry.
10) Guar gum acrylamide, a reaction product of guar gum with acrylamide, provides stability in an alkaline medium for textile printing.
11) Borate cross-linked guar gum is used in oil field drilling operations where it has been found to be more effective for the control of lost circulation.
