Polyacrylamide emulsion (Magnafloc E30) can be replaced by the Chinafloc EM series

 

Magnafloc E30 is a kind of anionic polyacrylamide emulsion produced by BASF. It has a hydrolysis degree of about 25% and a high molecular weight. It is widely used in water treatment and mineral processing.

 

Product introduction

Polyacrylamide emulsion by dispersion method or the inverse emulsion polymerization process, compared with the solid polyacrylamide dissolved time is fast, in the use of the limited cases, choose polyacrylamide (emulsion) dissolve quickly, simple and convenient, poly propylene amide latex besides having the advantages of solid polyacrylamide flocculant outside also have big optional sex charge density, dissolving speed, low energy consumption, Storage and easy to use and other features. Compared with traditional cationic polyacrylamide products, polyacrylamide emulsion is suitable for a wider range of PH value, higher charge stability, better flocculation effect, less drug use and a series of advantages. It is also suitable for the construction site without large dissolving device.

Polyacrylamide (emulsion)

 

Polyacrylamide emulsion by dispersion method or the inverse emulsion polymerization process, compared with the solid polyacrylamide dissolved time is fast, in the use of the limited cases, choose polyacrylamide (emulsion) dissolve quickly, simple and convenient, poly propylene amide latex besides having the advantages of solid polyacrylamide flocculant outside also have big optional sex charge density, dissolving speed, low energy consumption, Storage and easy to use and other features. Compared with traditional cationic polyacrylamide products, polyacrylamide emulsion is suitable for a wider range of PH value, higher charge stability, better flocculation effect, less drug use and a series of advantages. It is also suitable for the construction site without large dissolving device.

Application of polyacrylamide emulsion is widely used in a variety of domestic sewage, chemical wastewater, oilfield sewage, sludge dewatering treatment, papermaking and other industries, polyacrylamide oil water emulsion is also widely used in urban sewage treatment, brewery, amylase factory, food processing plants and other sewage treatment. It is especially suitable for flocculation sedimentation of organic suspended solids in acidic or acidic sewage. Paper industry used as retention aid filter agent, papermaking wastewater treatment. In petroleum industry, it can be used as emulsion coating agent or oil removing agent for drilling.

 

PAM precipitation is a chemical reaction that produces a substance insoluble in the solution in which the reactants reside. Precipitation removal under the action of gravity. This is a physical process, simple and easy to operate, good effect, is one of the important technologies of sewage treatment.

 

According to the nature and concentration of suspended matter and flocculation performance of polyacrylamide, precipitation can be divided into natural precipitation, flocculation precipitation, regional precipitation. The concentration of suspended particles in the zone precipitation is high (above 5000mg/L), and the sedimentation of particles is affected by other surrounding particles. The relative positions of particles remain unchanged, forming a common subsidence as a whole, and there is a clear mud-water interface with the clarified water. Regional precipitation occurred in both secondary sedimentation tank and sludge thickening tank.

Flocculation precipitation is the process of flocculation and precipitation of particulate matter in water. After adding coagulant in water, the colloidal and dispersed particles of suspended solids form floccule under the interaction of molecular force, and they collide and condense with each other in the sedimentation process, and their size and mass become larger and the sedimentation rate increases. The removal rate of suspended solids depends not only on the sedimentation rate but also on the sedimentation depth. Flocculation and precipitation will occur in the process of surface water alum flower, organic suspended solids in domestic sewage and activated sludge.

Precautions for Use

1, contact personnel in the use of polyacrylamide emulsion must wear protective equipment, skin contact parts should be immediately washed clean.

2. The operation site should be cleaned up in time to prevent slipping and falling.

 

Using the process

 

1, before using cationic polyacrylamide emulsion products, should be shaken as far as possible;

2. When dissolving, add the product while adding water. The solution concentration is recommended to be controlled at 1-5 ‰, and the ripening time should be 15-25 minutes.

3, avoid the use of centrifugal pump and other high shear rotor pump, the best use of screw pump, diaphragm pump and other low shear pump;

4, the dissolution operation should be carried out in the plastic, ceramic, stainless steel and other materials of the tank, the stirring speed should not be too large, without heating.

5, the prepared dilute solution should not be stored for a long time, it is good to dissolve with use;

6, polyacrylamide emulsion and inorganic coagulant compound use of wastewater treatment, should be added to the inorganic coagulant, to be obvious alum flowers (generally separated by 30-60 seconds or so), and then add the product, can not reverse the order, also can not be added at the same time.

Precautions for storage of polyacrylamide emulsion

1. At room temperature, the storage period is generally 6 months in an airtight container, and pay attention to avoid light;

2, small barrels in storage should pay attention to regular turning, shaking, to achieve full mixing, prevent stratification;

3, with a large container storage, to install a can stretch to the bottom of the container of multi leaf stirring, regularly open, or install a circulating pump regular circulation stirring, to ensure full mixing, prevent stratification.

4, the best storage temperature is, the product can not be frozen, otherwise it will affect its performance.

5, if the product once frozen phenomenon, to move to a higher temperature place, make it slowly defrost, before use to fully mixed, and 100 purposes sieve filter.

Polyacrylamide emulsion packaging and transportation:

1, 25KG plastic drum, 200KG plastic drum or ton drum packaging.

2, this product is a non-dangerous goods.
