Product Description

Important Property
HEC is a kind of non-ion aqueous agglomerate, white or yellow wish fluid power, no odor no taste, soluble in both hot and cool water, dissolving faster with temperature rising, usually insoluble in most organic solvents, with good pH stability,

Usage
HEC is used in industry as agent of dispersing, waterholding, thickening, suspending, film formation, stabilizing ect, For example, in emulsion coating. It plays a role of dispersing and protection gets, enhancing reaction stability of agglomerate system, ensuring homogeneous distribution of pigment and stuffing, and providing effect of thickening, improving fluidity. In petroleum exploitation, it is used as stabilizer and thickening agent, lubricating agent for well drilling, completing and consolidating to give slurry a good fluidity and stability, In building construction, used as thickening agent and cohesive agent to improve the fluidity and workability, inctrase initial gelling strength and avoid cracking, used in brushing and cohering plaster, it may be obviously raise water-holding and coherence strength, Used in daily use article such as toothpaste it give the article a good physical and chemical property, making it good in shape, long period of storage, hard be dry and permeated, in skin and hair protective articles, it can increase material density, adding lubrication and smoothness,
Method (1), Directly Put in
1. Pour pure water into bucket provided with stirrer
2. At beginning slowly stir, evenly scatter HEC into solution
3. Stir until all the HEC granules fully wetted
4. First put in anti-mildew agent, then add in additives entirely
5. Dissolved (viscosity in the solution obviously increasing ), then put in other ingredients to react.
Method (2) Prepare mother liquor for use

First prepare thick mother liquor, then put it in product. Then advantage of the method is flexibility, the liquor may be directly be put in product. The procedure and way to use is same as 1-4 in the method (1), be sure stir until fully dissolved into sticky and thick solution and put anti-mildew agent into mother liquor as early possible.

Method (3) Prepare Gruel-like material For Use
Since organic solvents are non-solvent for HEC, they can be prepare gruel-like material, the most used art ethylene glycol, propylene glycol and film forming agent( hexamethlene-glycol, diethyl glycol butyl acetate etc. ) So is ices water, it also can be prepared together with organic solvent into gruel-like material. Gruel-like material can be put in product because HEC in gruel-like material has been fully soaked and swollent up, put in product in dissolve immediately and promotes thickening, but do keep stirring until it entirely dissolves.
Usually the gruel-like material is obtained by mixing organic solvent or ices water HEC in a proportion of 6: 1, after 5-30 minutes HEC hydrolyzes and notably swells, The method is not adapted in summer owing to hot weather.
VI. Attention Matter for prepare HEC
(1)Before and after putting in HEC, do keep stirring until the solution become clarified and transparent.
(2)Put material slowly and evently in bucket, do not put large quantity of lumped HEC directly in bucket.
(3)Water temperature and pH have much to do with dissolving as showed in figure.
(4)Alkaline material is prohibited to put in compound before HEC is fully wetted, only after wetted can it raise pH and promote dissolving.
(5)Put in anti-mildew agent as early as possible.
(6)When high viscosity HEC is used, the mother liquor density is not allowed to be over 2.5-3%, otherwise mother liquor will be hard controlled.
Packing, Storage and Shipment
20 Kg or 25Kg net weight packed in paper plastic compound bag or plastic-coated bag lined with plastic bag, prevent sunshine, keep away from fire and wet.
