water decoloring agent LSD-01
CAS No.: 55295-98-2
Product Name: LSD-01 decolorant polymer
Chemical Name: Dicyandiamide condensation resin (PolyDCD)
LSD-01 decolorant polymer is a dicyandiamide based cationic copolymer with a medium
molecular weight. It is active with the majority of dyes used in industrial processes, it is
effective through the formation of organic complexes with the dye molecule and the subsequent
removal of the complex’s solid particles by flocculation and sedimentation.
|Appearance||Colorless or light-color sticky liquid|
|Dry weight (%,120°C, 6h)||≥50.0|
|PH Value (30% water solution)||2.0-5.0|
|Viscosity (mpa.s 20°C)||30-1000|
It is mainly used for color removal treatment for high-colority
waste water from dyestuffs plants. It is suitable to treat waste
water with activated, acidic and disperse dyestuffs.
It can also be used to treat waste water from textile industry and
dye houses, pigment industry, printing ink industry and paper
Application method and notes:
1. The product shall be diluted with 10-40 times water, then added to
the wastewater directly. After stirring for several minutes, the
clear water will be got by precipitation or air-floatation.
2. The optimized pH of the wastewater accepted is 6-10.
3. It is recommended to use this product with the inorganic
flocculants to treat the effluent with high color and COD to reduce
the operation cost. The order and proportion of agent dosage depend
on the flocculation test and the effluent treatment process.4. The product is nonflammable and unexplosive.
5. The product would show layer separation and become white at low
temperature. There is no negative impact on the usage after mixing
Packing and storage:
Store in room, recommended temperature 5-30°C.
The product is packed in 250kg/drum, or 1250kg/IBC.
|Appearance||Colorless or light-color sticky liquid||Light yellow sticky liquid|
|PH(30% water solution)||3.0-5.0|
