Polyacrylamide Introduce:

Polyacrylamide (Pam) Produced By New Water Purification Is A Water-Soluble Polymer, Insoluble In Most Organic Solvents, Has Good Flocculation, Can Reduce The Friction Resistance Between Liquids, According To Ionic Characteristics Can Be Divided Into Non-Ionic, Anion, Cation And Amphoteric Four Types.

Polyacrylamide Mesh Number: Mesh Number Refers To The Particle Size Or Thickness Of The Material, Mesh Number Is The Number Of Squares Per Unit Area.  The General Definition Refers To The Number Of Mesh Holes In An Area Of 1 Inch 1 Inch, That Is, The Number Of Mesh Holes In The Screen.  Such As 600 Mesh Is 600 Square Mesh Per Square Inch, The Mesh Number Of Polyacrylamide 20 Mesh To 80 Mesh, That Is, Between 0.85mm And 0.2mm, This Is The Size Of The Granular Polyacrylamide Mesh Size Can Be Controlled At About 100 Mesh, The Larger The Mesh Size Of Polyacrylamide More Easily Dissolved, The Size Of The Polyacrylamide Mesh Alone Can Not Measure The Quality Of The Product!

Polyacrylamide (Pam) Is A Water-Soluble Polymer, Insoluble In Most Organic Solvents, Has Good Flocculation, Can Reduce The Friction Resistance Between Liquids.

Polyacrylamide Working Principle:

1) Principle Of Flocculation: When Pam Is Used For Flocculation, It Is Related To The Surface Properties Of The Flocculated Species, Especially The Electrokinetic Potential, Viscosity, Turbidity And The Ph Value Of The Suspension. The Electrokinetic Potential Of The Particle Surface Is The Reason For The Agglomeration Of The Particles. Adding Pam With Opposite Surface Charge Can Reduce The Electrokinetic Potential And Coagulate.

2) Adsorption Bridge: The Polyacrylamide Molecular Chain Is Fixed On The Surface Of Different Particles, And The Polymer Bridge Is Formed Between The Particles, So That The Particles Form Aggregates And Settle.

3) Surface Adsorption: Various Adsorption Of Very Functional Group Particles On Polyacrylamide Molecules.

4) Enhancement: Polyacrylamide Molecular Chain And Dispersed Phase Through Various Mechanical, Physical, Chemical And Other Effects, The Dispersion Is Implicated Together, Forming A Network.

Polyacrylamide Usage Characteristics:

1, flocculation: polyacrylamide can make suspended substances through electric neutralization, bridge adsorption, flocculation.

2, adhesion: through mechanical, physical, chemical action, play a bonding role.

3, resistance reduction: polyacrylamide can effectively reduce the friction resistance of the fluid, adding a trace of PAM in water can reduce the resistance of 50-80%.

4, thickening: Quanxin water purification materials Co., LTD. - Supplier of Quanxin water production of polyacrylamide in neutral and acid conditions have a thickening effect, when the PH value is more than 10 PAM easy hydrolysis.  The thickening will be more pronounced when the structure is semi-reticulated.

Polyacrylamide Application Scope:

1, Widely Used In Industrial Wastewater Treatment, For Suspended Particles, Coarse, High Concentration, Ions With Positive Charge, Water Ph Value Is Neutral Or Alkaline Sewage, Steel Plant Wastewater, Metallurgical Wastewater, Coal Washing Wastewater Treatment Effect Is Good.

2, Used In Petroleum Industry, Oil Production, Drilling Mud, Waste Mud Treatment, Prevent Water Channeling, Reduce Friction, Improve Recovery, Three Times Oil Recovery Widely Used.

3, Used For Textile Sizing Agent, Stable Slurry Performance, Less Pulp, Low Fabric Break Rate, Clean Cloth.

4, Used In The Paper Industry. One Is To Improve The Retention Rate Of Fillers And Pigments; The Second Is To Improve The Strength Of The Paper (Including Dry Strength And Wet Strength). In Addition, It Can Also Improve The Tear Resistance And Porosity Of Paper To Improve Visual And Printing Performance, And Is Also Used In Food And Tea Paper.

Polyacrylamide Usage Instructions:

1, The Use Of Cationic Polyacrylamide For Coal Washing Can Be Set Between 30 Kg And 110 Kg;   The Amount Of Wastewater Used In The Chemical Industry Is Generally Between 50 And 120 Kilograms;   The Wastewater Of The Bleaching And Dyeing Industry And The Wastewater Of The Paper Industry Are More Difficult To Treat, And The Amount Of Use Should Be Increased, And The Amount Of Use Is Set At 100 To 300 Kilograms, And The Electroplating Wastewater Industry And Ordinary Industrial Water Generally Do Not Exceed 50 Kilograms.Note: (The Amount Used In These Industries Is The Amount Of Wastewater Per Thousand Tons).

2, Domestic Sewage According To The Different Treatment Methods Of Desliming Flocculants Are Not The Same.

If The Main Process Adopts Biochemical Methods, That Is, The Dehydration Of The Remaining Sludge (Which May Contain Some Initial Sediment), Only Cationic Pam Is Needed As A Sludge Dehydrating Agent.

If The Main Body Of The Process Uses Physical And Chemical Methods, Such As A Strengthening, Loading Magnetic Separation And Other Processes, It Is Generally To Add Pac Tempering First, And Then Add Anionic Flocculant, And Then Add Cation Flocculant Dehydration.   The Specific Dosage Should Be Determined According To The Sewage Quality.

There Are Also Many Sewage Treatment Stations, Sludge Dehydration Directly Add Pac Or Other Inorganic Flocculants Can Be, This Is Widely Used In Plate And Frame Filter Press, Especially Electronics Plants Or Small Sewage Treatment Stations.

When Used As A Sludge Dehydrating Agent, The Ratio With Water Is Generally Between 0.1% And 0.2%.After It Is Dissolved Into A Glue-Like Liquid, It Is Added To The Sludge For Mixing Treatment.

The Ratio Of Sludge Is Generally 5%-10%, And Some Are Lower, Which Should Be Determined According To The Concentration Of Sludge, And It Is Better To Determine The Best Dosage And Use Model Through The Beaker Experiment On Site.Different Sludge, Different Agents, Different Equipment, Different Management Levels, The Treatment Effect Of Sludge Is Different.

3, The Sewage Treatment Plant Uses Cationic Polyacrylamide As Sewage Operation Sludge Dehydrating Agent.In The Process Of Communicating With Customers, Customers Often Ask About The Amount Of Sludge Dewatering Agent Added In The Process Of Sewage Treatment Sludge Dewatering.To Know The Dosage Of Sludge Dehydrant Relatively Accurately, First Understand These Parameters, The Moisture Content Of Sludge, The Moisture Content Of Mud Cake, The Amount Of Mud, The Amount Of Medicine, The Concentration Of Medicine And So On.

Sludge Moisture Content: The Percentage Of The Weight Of Water Contained In The Sludge To The Total Weight Of The Sludge Is Called The Sludge Moisture Content.

Mud Cake Moisture Content: The Percentage Of The Weight Of Water Contained In The Mud Cake To The Total Weight Of The Sludge Is Called Mud Cake Moisture Content.

Also Through The Following Formula To Calculate

1, Dosage Mg/L= Dosage Quality/Treatment Water/Dosage Concentration

2, Treatment Water Dosage = Treatment Water M3/H/Dosage G/M3

3, Dry Mud Amount = Water Treatment [(1- Sludge Moisture Content)/(1- Mud Cake Moisture Content)]

4, Per Ton Of Dry Mud Drug Consumption G/M3= Dosage/Amount Of Dry Mud

The Error Of The Above Calculation Results May Be Relatively Large, And It Is Only For Reference During Sewage Operation.The Actual Drug Consumption Should Be Tested By Actual Machine Operation.
