Ink Water Decolorizing Chemicals PolyDCD
Quaternary Ammonium Cationic Copolymer Decoloring Agent
Description:
The water decolorant, which consists of dicyandiamide - formaldehyde resin, can efficiently eliminate the color from dye - containing wastewater via a two - pronged mechanism. As a quaternary ammonium cationic copolymer, it releases a large number of cations. These cations counteract the negative charges on the dye molecules, thus disrupting the stability of their colloidal structure. At the same time, its hydrolysis gives rise to large flocculent substances (such as the CW - 08 formula), which can adsorb and encapsulate the destabilized dye particles. This integrated process of charge neutralization and flocculation allows for the effective separation of dyes from water. This decolorant shows excellent performance in terms of decolorization, floc generation, and reduction of chemical oxygen demand (COD). Therefore, it is especially well - suited for treating intricate industrial dye wastewater.
Application:
- This substance is principally applied to decolorize highly - colored effluents in dye manufacturing plants, particularly those containing reactive, acidic, and disperse dyes.
- It has the capacity to handle wastewater stemming from sectors like the textile industry, dyeing facilities, pigment production, printing ink manufacturing, and paper - making processes.
- Additionally, within the paper and pulp industry, this product serves as a retention agent in the production stage.
Instructions for use:
- Prior to adding the product to the wastewater, it must be diluted with water in a ratio of 1 part product to 10 - 40 parts water by volume. After several minutes of stirring, clear water will be obtained either through sedimentation or air flotation processes.
- To achieve optimal treatment outcomes, the pH value of the wastewater should be maintained within the range of 6 to 10.
- For treating highly - colored effluents with high Chemical Oxygen Demand (COD), it is recommended to use this product in combination with inorganic flocculants. This approach can help cut down on operating expenses. However, the dosage and the order of application should be determined according to the results of flocculation tests and the specific treatment procedures.
- In low - temperature conditions, the product may exhibit layer separation and turn white. Nevertheless, thorough mixing will guarantee that its performance remains unaffected.

Advantage:
The water decolorant demonstrates remarkable decolorization capabilities, being able to remove 85 - 95% of dyes from the solution. It also effectively reduces the Chemical Oxygen Demand (COD) by around 60%, showing faster sedimentation rates and improved flocculation properties. What's more, this decolorant is environmentally friendly as it is free from harmful substances like aluminum, chlorine, and heavy metal ions.
Success Cases:
Decolorization of whiteboard water - based pen ink
1. The customer sent a wastewater sample: It was red and thick, with a pungent odor.
2. Customer's requirement: Decolorization.
3. Experimental results
4. After adding the decolorizer, flocs gathered and the water quality became significantly clearer. There were no impurities at all after filtration. The customer was very satisfied.
Package and Storage:
