Nonionic Flocculants

SINOFLOC nonionic flocculants are technically pure polyacrylamides. Nonionic polyacrylamide exhibits neutral nonionic properties in the aqueous solution which is hardly influenced by the PH value in the application. SINOFLOC nonionic flocculants are suitable for use as a settlement aid in many different mineral-processing applications and are particularly effective under very low PH conditions, as encountered in acidic leach operations.

Products Feeding:

The solutions of SINOFLOC nonionic PAM must be prepared in suitable plants equipped with dry powders feeding and dispersion units and with continuous and moderate agitation. The dissolution water must have a temperature included between 10°C and 40°C; For a correct use of SINOFLOC nonionic polyelectrolyte and in order to achieve the best possible results, it is necessary to allow a “maturation” time of 60 minutes. When treating turbid water, the flocculants solution must be added to the water in a point of average turbulence, in order to achieve a thorough and homogeneous mixing without impairing the flock formation. Recommend operating concentration is 3g/l, and the maximum operating concentration is 15g/l. For an optimum performance on specific applications on nonionic flocculant, please consult with SINOFLOC team.

What is the Charge of Sinofloc Nonionic Polyacrylamide?
Sinofloc is supplying dry powder flocculants with charge under 5%.
What is the Main Characteristics of Sinofloc Nonionic Polymer?
Our nonionic polymer flocculants is amorphous, free-flowing powder, with Molecular Weight: 5 to 15 million.
What Kinds of Nonionic Polyacrylamide are Available in Sinofloc?
Sionfloc nonionic polyacrylamide is available in solid status.
What’s the Main Application for Nonionic Flocculants?
Nonionic Flocculants is widely used in industrial wastewater treatment, mineral process, paper making and other industries. 
What's the Nonionic Polyelectrolyte Flocculation Principle?
The nonionic polyacrylamide (PAM) has strong flocculation effect as it has good performance in clarifying & purification, settlement promotion, filtering promotion and thickening. All this makes good application in wastewater treatment, sludge concentration and dehydration, mineral processing, coal washing, paper making, etc..
What is the Nonionic Polyacrylamide Characteristic?
Sinofloc nonionic polyacrylamide has good water solubility even in cold water. Moreover nonionic polyacrylamide can be greatly flocculated under a small dosage like 0.01~10ppm. And our nonionic polymer shows a great performance when joint using with inorganic flocculant like polymerized ferric sulfate, poly aluminum chloride, and iron salt.
What is Application Status of Nonionic Polymer in Paper Making?
Sinofloc Polymers could be used as paper strength agent, retention aid and filter aid in paper making. It can greatly improve the quality of paper, save costs and improve the production capacity of paper mills. Our nonionic polymers could be work with inorganic salt ions, fiber and other organic polymer in order to enhance the physical strength of the paper, and also reduce the loss of fiber or filler. It also has good performance to accelerate filter water, strengthening, retention and drainage effect. 
Could Nonionic Polyacrylamide Be Used in Construction Field?
Nonionic polyacrylamide is widely applied in the field of building materials as an external additive for concrete, which can improve the interaction between concrete particles and thereby the strength and toughness of concrete is increased. The application of nonionic polyacrylamide in building materials has been widely promoted owing to its role of flocculation, water holding, thickening, adhesion and lubrication. In addition, non-ionic polyacrylamide in other building materials, because of its ultra-high viscosity and its special molecular structure, has good water retention effect. The most common use is as a thickening agent for putty powder, refractory binder, mortar thickening water retention agent.
Could Nonionic Polyacrylamide Be Used in Dyeing Wastewater Treatment?
Nonionic flocculants can be used in dyeing wastewater treatment to make most of the non-water soluble dye particles and colloidal organic matter condensed into large particles and then removal through natural sedimentation, flotation.
Could Nonionic Polyacrylamide Be Used in Industrial Wastewater Treatment?
It's more appropriate to use nonionic polyacrylamide as flocculants when the suspension of sewage is acidic. The suspending particles produce flocculation to purify water. When used in the city sewage, food processing waste water treatment, sludge dewatering, the positive charge could have neutralize effect with negative sludge groups in organic gel. Through high polymer excellent bridging condensed function, colloidal particles aggregate into large floc and separate from the suspension. 
Could Nonionic Polyacrylamide Be Used in Agriculture?
Nonionic Polyacrylamide could be used in sand prevention and sand fixation through spraying on desert with dissolving nonionic polyacrylamide concentration and crosslinking agent. This product could also be used as soil moisturizer and the basic raw materials for various modified polyacrylamide.
Why is Polyacrylamide Used as Flocculants?
Polyacrylamide is most commonly used as flocculants, abbreviated as PAM. Flocculants is the linear polymer. Besides polyacrylamide solid aluminum sulfate, liquid aluminum sulfate, alum, polyaluminum chloride, ferric chloride, ferrous sulfates are also used as flocculants.
How to Storage Polyacrylamide Well?
First, select a well-ventilated and dry warehouse, and to reduce the time of sunlight as the sun exposure will make polyacrylamide molecular weight degradation. Moisturizing polyacrylamide is easily to agglomerate and hard to dissolve as an aqueous solution during dissolution. If in a solution case, after the polyacrylamide dissolved in aqueous solution not used up, the remaining polyacrylamide solution should be filled with a lid seal to prevent dust from entering. The storage time of polyacrylamide is 48 hours. The solution becomes thinner when the polyacrylamide solution is stored for an extended period of time. 
How is Sinofloc Service Team?
Sinofloc technical team could provide in-house testing and lab facilities to optimize products performance with the best combination of flocculants in your conditions. 
As one of the top polyacrylamide suppliers, Sinofloc has the ability and experience to ship our flocculants to any port in the world. Door to door practice is also available.

Preparation Products Solution

Powder polyacrylamide flocculants couldn’t be directly feed to the sewage. It is necessary to dissolve it in water first and then use its water solution to treat the sewage. The water to dissolve the granular polymer should be clean (such as tap water), rather than sewage. The water at the normal temperature is workable, no need to be heated. When the water temperature is less than 5oC, the dissolution is very slow. The speed of dissolution will be increased along with water temperature get higher, but if it is more than 40oC, the degradation of the polymer will be accelerated. 

Nonionic Flocculants for Mineral Processing

Sinofloc nonionic flocculants with high or very high molecular weight could be used in sedimentation or centrifugation, with good performance and cost efficiency.
