Polyacrylamide Production Process

①Aqueous solution polymerization colloid Polyacrylamide production process The low concentration (8% ~ 12%), or medium concentration (20% ~ 35%) polyacrylamide aqueous colloid production process is: ion exchange to refine acrylamide monomer aqueous solution, adjust the solution Temperature to 20 ~ 50 ℃, blowing N2 gas for 20min to remove oxygen in the solution. Potassium persulfate-sodium bisulfite initiator solution is added to initiate polymerization for 4-8 hours to obtain a colloidal product of polyacrylamide aqueous solution.
②Aqueous solution polymerization powder polyacrylamide production process Aqueous solution polymerization powder polyacrylamide production process can be divided into low concentration and high concentration polymerization according to the monomer concentration.
The low-concentration (about 10%) aqueous solution polymerization powdery polyacrylamide production process is to polymerize about 10% of AM to form drools on a steam-heated drum to form flakes. As the drum slowly rotates, the PAM is heated and dried. After the dry PAM is scraped off the drum, it is pulverized to obtain a powdered product.
The production process of medium concentration (20%-30%) aqueous solution powdery polyacrylamide consists of three parts: polymerization, granulation and drying in medium concentration (20%-30%) AM aqueous solution. The polymerization process is divided into sheet (conveyor) polymerization and bulk (polymerization kettle) polymerization.
a. Sheet polymerization process The heat released during adiabatic polymerization of AM with a concentration (content) of 20% to 30% can increase the temperature of the system by 60 to 90 °C. Due to the high viscosity of PAM, effective mechanical stirring is difficult even in the initial stage of the polymerization reaction, so acrylamide (AM) aqueous solution can be coated on concave steel plates or conveying steel belts for thin-layer polymerization. The belt speed is controlled so that the polymerization is complete when the polymer reaches the end point. Adding surfactant, isopropanol or glycerin to the original reaction solution, or coating the steel belt with a fluorine-containing polymer film, can ensure that the polymer does not stick to the carrier. This makes it possible to complete the polymerization at high monomer concentrations (20% to 45%) and over a wide temperature range. After the acrylamide polymer is removed from the steel belt, it is crushed, dried and packaged.
b. Bulk polymerization process The polymerization process in which the polymer does not exchange with the environment is called adiabatic polymerization. AM aqueous solution with a concentration (content) of 20% to 35% is initiated at a temperature of 5 to 20 °C in the presence of a redox system. The polymerization temperature of the reaction block during this polymerization process can reach or even exceed 100°C, and the polymer will maintain this temperature for 20 h. The polymer gel was broken up with a screw extruder and then dried. During the crushing and drying process, antiblocking agents and structural stabilizers are added to the polymer. The polymer gel is broken into particles of 0.2-5mm size, and if the surface of the particles is coated with a material slightly moistened with water, a polymer gel that is easy to store and not sticky can be obtained without drying.

How to Choose the Correct Type of Polyacrylamide?

1. Acknowledge the source of sludge

Sludge is an inescapable item in sewer therapy. First off, we need to comprehend the source, nature, cosmetics as well as strong material of sludge. According to the numerous significant parts consisted of in sludge, sludge can be split right into natural sludge in addition to not natural sludge. Generally speaking, cationic polyacrylamide is utilized to handle natural sludge, along with anionic polyacrylamide is used to take care of not natural sludge. It is challenging to utilize cationic polyacrylamide when it is truly alkaline, in addition to it is not appropriate to utilize anionic polyacrylamide when it is extremely acidic. When the solid internet content is high, the quantity of polyacrylamide is generally larger.

2. Ionic degree option of Polyacrylamide

For the sludge to be dewatered, flocculants with various ionic levels can be made use of to screen through little experiments to pick the best perfect polyacrylamide, so that the absolute ideal flocculant outcome can be achieved, as well as likewise the dosage of chemicals can be lowered, saving rates. The method to choose ion level is to see:
(1) The measurement of the floc
The size of the flocs: furthermore small flocs will definitely affect the speed of water drain, and also in addition significant flocs will bind a whole lot even more water along with decrease the level of mud biscuit. The measurement of the flocs can be changed by picking the molecular weight of the polyacrylamide.
(2) floc sturdiness (wetness internet material). Toughness of flocs: The flocs need to remain to be constant without breaking under shear. Boosting the molecular weight of polyacrylamide or choosing an ideal molecular structure can assist to enhance the floc defense.
(3) Combining of Polyacrylamide along with Sludge. Polyacrylamide needs to totally react with the sludge at a particular positioning of the dewatering gadgets to trigger flocculation. To this end, the viscosity of the polyacrylamide service should be appropriate, in addition to it can be totally integrated with the sludge under the existing tools troubles. Whether both are combined consistently is the essential variable for success. The viscosity of polyacrylamide solution is related to its molecular weight in addition to remedy emphasis.
(4) Dissolution of polyacrylamide. Just when the dissolution is terrific can the flocculation result be completely put in. As explained above, the dissolution treatment of polyacrylamide is genuinely the aging treatment of polyacrylamide. Generally it is required to enhance the dissolution rate. Presently, it is practical to consider enhancing the focus of polyacrylamide choice. Consequently, the most reliable product alternative need to be determined by lab beaker experiments.

3. Molecular weight option of Polyacrylamide.

The molecular weight of polyacrylamide clarifies the measurement of the molecular chain in the particle. The molecular weight of polyacrylamide remains in between 5 million and also additionally 18 million. Normally speaking, the better the molecular weight of the polyacrylamide product, the greater the viscosity. Nevertheless, when utilizing, It is not a thing with a greater molecular weight, the much better the usage impact. Especially, in operation, the appropriate molecular weight of polyacrylamide require to be established according to the actual application sector, water excellent quality, treatment tools along with numerous other problems.

Polyacrylamide is a macromolecule coagulant. According to its average molecular weight, the things can be divided right into 3 classifications: low molecular weight (<1 million), medium molecular weight (2-4 million) and high molecular weight (>< 1 million), tool molecular weight (2-4 million )as well as high molecular weight( > < 1 million ), medium molecular weight (2-4 million )as well as additionally high molecular weight (> < 1 million), device molecular weight( 2-4 million) and also high molecular weight (> 7 million ).

Polyacrylamide is made use of in sewage system therapy, along with it is a high molecular water-soluble all-natural polymer with a molecular weight of a selection of million to tens of millions. Residential polymer polyacrylamides consist of: non-ionic polyacrylamide (reduced as NPAM, molecular weight 800-15 million), anionic polyacrylamide (shortened as APAM, molecular weight 800-20 million), cationic polyacrylamide (minimized as CPAM, molecular weight 800 -12 million, ionicity 10% -80%).

If it is simply made use of as a coagulant, the better the molecular weight is, the tighter the flocs will definitely be, along with the extra economical the drug will absolutely be. However, the molecular weight of anionic Polyacrylamide is recommended not to go beyond 20 million.

In relation to sludge dewatering. When utilizing a belt filter press, the molecular weight ought to not be costly. If the molecular weight is likewise pricey, the filter towel may be obstructed and the dehydration result will absolutely be influenced. For instance, if you use a centrifugal filter press, the molecular weight demand will definitely be much better.

The filter needs the floc to be as unsusceptible to shearing as feasible, so an item with a relatively high molecular weight should be chosen.
