ZHENGXI AC pigment chips are pre-dispersed pigments in water soluble styrene- acrylic resins. Water based acrylic pigmented chips can be used to formulate water based inks & paints with excellent compatibility and gloss. The chips are soluble in a combination of water, alkali(ammonia or another amine).
ZHENGXI AC pigment chips offer maximum flexibility in formulation of high quality waterborne printing inks, pains and coatings.
Main applications are as follows:
●PRINTING INKS
Paper & corrugated
Foil
Cellophane
Pre-treated PE or PP
●PAINTS & COATINGS
Industrial Paints
1. Waste Water Treatment
Printing with water-based inks will usually produce colored water from cleaning print rolls and fountains. The following Procedures can remove the entire color and binder wastes from the water, and may also be used to treat waste ink and waste water.
⑴To Waste water containing 1-2% binder solids, add 1.5 lbs of ferric chloride or aluminum sulfate per 100 gallons of water (0.18 kilos/100 liters).Stir until the mixture is uniform. For minimum dissolved salts in the waste water, use aluminum sulfate.
⑵The with good mixing, add approximately 1.5 lbs.(0.18 kilogs/100 litres) of calcium hydroxide. Adjust the PH to about 7.
⑶Let the flocculation solids settle. Then pour off the clear liquids into water disposal system and dispose off the wet solids or rubbish. The solids will be non-toxic except for wastes from heavy metal containing inks.
