water decoloring agent LSD-01
CAS No.: 55295-98-2
Product Name: LSD-01 decolorant polymer
Chemical Name: Dicyandiamide condensation resin (PolyDCD)
- Lansen is the biggest manufacturer of water decoloring agent in
- LSD-01 Water Decoloring Agent is cationic polyelectrolyte, which
has high color removal of dye wastewater, by providing a large
number of cations, the negative charge is brought on dye molecules
are neutralized instability, at the same time with BWD-01 Water
Decoloring Agent by a large number of hydrolysis of flocs. Can be
adsorbed dye, destabilization of the snare, from water separation,
so as to achieve the purpose of bleaching.
- It is specially working high performance with the dyeing wastewater
containing the hydrophilic dyes (reactive dyes, acid dyes, disperse
dyes etc.), less dosage, the color clear, fast speed, high
processing liquid clarification of the settlement, but also reduce
the composition of COD, improve the COD removal rate.
- Soluble in water, safe, non-toxic, hydrolytic stability, is not
sensitive to the change of pH value, anti-chlorine. Harmless,
no-flammable and non-explosive, it can be stored at room
temperature, it cannot be placed in the sun. It is slightly acidic,
when skin contact, wash immediately with plenty of water.
|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|
