What is the smell of polyamine?
The odor of polyamines is generally described as putrid. This characteristic odor can be detected in water at apparent levels of 17, 18, 115 and 155 ppm for putrescine, spermine, spermidine and cadaverine, respectively.
Polyamine is a low molecular weight, very high charge density cationic polyamine. It is supplied as a clear to opaque liquid, low viscosity aqueous solution. It is a cationic polymer that performs well in the pH range 2.5 to 12.0.
Polyamine is an organic compound having more than two amino groups. Alkyl polyamines occur naturally but are also synthetic. Alkylpolyamines are colorless, hygroscopic, and water soluble. Near neutral pH, they exist as the ammonium derivatives. Most aromatic polyamines are crystalline solids at room temperature.
Polyamine is an organic polymer that is very effective in coagulating colloidal dispersions. It is especially effective as a deposit control agent when applied to pulp, stock, wires, or felts. It is also effective in removing organics and color from recirculating or effluent streams in pulp and paper mills. However, the most cost effective product should be selected based on a performance evaluation using the particular feed or stream intended for treatment. It may be fed neat or diluted in-line into the point of treatment.
The dosage will depend upon the severity of the problem. When applied to pulp or stock for deposit control, the dosage can range from 0.25 - 2.5 Kgs of polyamine per ton of pulp or stock (dry basis).
When it is applied for control of deposits on the forming fabric, the dosage can range from 0.10 - 1.0 ml/min per 1 foot of fabric width.
[Storage and handling]
Polyamine should be stored at 50–90°F.Short-term exposure to higher or lower temperatures will not normally harm the product. If frozen, it should be warmed to 80 – 100°F. and mixed well prior to use.
The shelf life:12 months.
