Cationic polyacrylamide
1, the water solubility of cationic polyacrylamide is good, even in cold water, it can be completely dissolved.
2, add a small amount of cationic polyacrylamide, which can have a significant flocculation effect. Generally, only 0.01 to 10 ppm (0.01 ~ 10g / m3) can be added to make full play.
3, simultaneously using cationic polyacrylamide and inorganic flocculant (polymerized sulfate, polymerization aluminum chloride, aluminum salt or iron salt, etc.), can show a greater effect.
Cationic polyacrylamide instructions:
1. When using, the water dissolved particulate cationic polyacrylamide should be clean (such as tap water), and cannot be sewage. Temperature water, the water temperature is slow than 5 ° C, the water temperature is slow, and the water temperature increases the rate of dissolution speed, but the PAM can accelerate the degradation, affecting the use effect. Generally, tap water is suitable for formulate polymer solutions. Strong acid, strong base, high salt-containing water is not suitable for formulation.
2, when dissolved, the cationic polyacrylamide is uniformly sprinkled into the stirred water, and the stirring is controlled at 100 to 300 rpm. Adjustably heating (<60 ° C) can accelerate dissolution.
3. Adjust the pH of the treated liquid to make the cationic polyacrylamide functions (select the appropriate pH and dosage by test.)
4, when the cationic polyacrylamide solution is added, the mixing of the treated liquid should be accelerated, and the flocculation is increased, stirring is slowed, and the growth and accelerated settlement of the flocculation.
Cationic polyacrylamide packaging and storage:
Cationic polyacrylamide is packaged in 25kg paper-plastic composite bag, or according to user requirements.
When stored, pay attention to heat-resistant, moisture-proof, prevent packaging damage, and dry powder products long-term appearance will suck the moisture.
The number of stacked layers must not exceed 20 layers, and the effective storage period is 2 years, and the solution is prepared (1-3 days).

Applications
Cationic polyacrylamide application range:
1 the corresponding model for sludge dehydration can be used according to the sludge properties which can effectively dehydrate before the sludge into the filtration dehydrated resulting in a large non-viscosity filter pressing filter It is not scattered the mud cake is thick the dehydration efficiency is high and the water content of the mud cake is below 80%.
2. As the flocculant it is mainly used in industrial solid-liquid separation processes including sedimentation clarification concentration and sludge dehydration etc. The main industries include: urban sewage treatment paper industry food processing industry petrochemical industry Wastewater treatment of metallurgical industries ore industry dyeing industry and sugar industry and various industries. Used in urban sewage and meat poultry food processing wastewater treatment the positive charge group contained in the negative charge organic rubber electrical properties in the sludge contained in the sludge contained. The bridge coacervation function excellent in polymers causes colloidal particles to collect into large blocks separated from its suspension. The effect is obvious and there is less investment.
3. Cationic polyacrylamide is used in oilfield aids such as clay discresens and iron-acidized thickeners.
4 cationic polyacrylamide is used in the paper industry one is to increase the retention rate such as filler pigment. To reduce the loss of raw materials and pollution to the environment; the second is to increase the strength of the paper (including dry strength and wet strength) in addition using PAM can also improve paper anti-tearness and porousness to improve visual and printing performance In food and tea packaging paper.
5 cationic polyacrylamide is used in the treatment of flocculant with river water source water source small amount good effect low cost especially and inorganic flocculant composite use effect it will become the Yangtze River the Yellow River and The efficient flocculant of the tap water plant in other basins.
6. It is used for textile and printing and dyeing industries. Cationic polyacrylamide is a protective layer of a fabric treatment of the slurry finishing agent and a protective layer that can be formed into a soft anti-wrinkle and anti-bacteria. Using its characteristics of moisture absorption the discharging rate when the spinning yarn is reduced. Polyacrylamide post-treatment agent can prevent static and flame retardant of fabrics. When used as a printing additive the polyacrylamide can make the product adhere to a large fault high and bright and can also be used as a bleached non-silicon polymer stabilizer.
