Polyacrylamide (PAM) is a synthetic polymer composed of repeating units of acrylamide. It is widely used as a flocculant, thickener, and binder in various industrial processes, including water treatment, papermaking, mining, and petroleum production. Here is an introduction to the physical and chemical properties of polyacrylamide:

1. Molecular Structure: Polyacrylamide is a linear polymer with a molecular weight ranging from a few thousand to several million Daltons. It consists of long chains of acrylamide monomers linked together by amide bonds (-CONH-). The structure of polyacrylamide can be modified by copolymerization with other monomers to incorporate specific properties.

2. Solubility: Polyacrylamide is highly soluble in water, forming clear and viscous solutions. It has the ability to absorb and retain large amounts of water, which contributes to its excellent water treatment properties. The solubility of PAM can be affected by factors such as molecular weight, ionic strength, and pH.

3. Ionic Character: Polyacrylamide can be classified into two main types based on its ionic character: nonionic and anionic/cationic. Nonionic PAM is electrically neutral, while anionic PAM carries negative charges and cationic PAM carries positive charges along the polymer chain. The ionic character determines the interactions of PAM with other substances and its performance in different applications.

4. Flocculation and Dispersion: Polyacrylamide exhibits flocculation properties, meaning it can cause the aggregation of suspended particles in a liquid. The polymer chains form bridges between particles, leading to the formation of larger, settleable flocs. This property is extensively used in water and wastewater treatment processes.

5. Rheological Properties: Polyacrylamide solutions display high viscosity, which is desirable in applications such as thickening and emulsion stabilization. The viscosity is influenced by factors like molecular weight, concentration, and temperature. PAM solutions can form gels under specific conditions, allowing them to act as thickening agents.

6. Stability: Polyacrylamide is stable under normal conditions, but its stability can be affected by factors such as temperature, pH, and the presence of oxidizing agents. High temperatures can cause the degradation of PAM, leading to a decrease in its performance.

7. Biocompatibility: Polyacrylamide is generally considered safe for use in industrial applications. However, its use in certain consumer products, such as cosmetics, may require additional scrutiny to ensure safety. It is important to follow proper handling and disposal practices to minimize environmental impacts.

Overall, the physical and chemical properties of polyacrylamide make it a versatile polymer with a wide range of applications in various.

The preparation of polyacrylamide involves a polymerization reaction of acrylamide monomer using a suitable initiator. Here are the main steps involved in the preparation process:

1. Monomer Selection: Acrylamide (CH2=CHCONH2) is chosen as the primary monomer for polyacrylamide synthesis due to its reactivity and ability to form long polymer chains.

2. Initiator Selection: A chemical initiator is required to initiate the polymerization reaction by generating free radicals. Common initiators for polyacrylamide include ammonium persulfate (APS) and N,N,N',N'-tetramethylethylenediamine (TEMED).

3. Polymerization: The polymerization reaction usually takes place in an aqueous solution. Here are the steps involved:

   a. Preparation of Monomer Solution: Acrylamide monomer is dissolved in water to create a monomer solution. Depending on the desired polymer properties, co-monomers or crosslinkers may be added to the solution.

   b. Initiator Addition: The initiator, such as APS and TEMED, is added to the monomer solution. APS decomposes in water to generate sulfate radicals, while TEMED helps initiate the reaction.

   c. Initiation: After adding the initiator, the reaction mixture is typically heated to a suitable temperature, often around 60-70°C. This initiates the formation of free radicals.

   d. Polymerization: Free radicals produced by the initiator react with acrylamide monomers, causing them to join together and form long polymer chains. The reaction proceeds until all the monomers are consumed or until terminated by adding a termination agent, such as ammonium persulfate or hydrogen peroxide.

   e. Post-Reaction Treatment: After the desired reaction time, the reaction mixture is often cooled and subjected to further processing steps, such as filtration, precipitation, or drying, to obtain the final polyacrylamide product.

It's important to note that the polymerization process can be modified by adjusting various parameters such as monomer concentration, initiator concentration, reaction temperature, reaction time, and the addition of crosslinking agents or functional groups, to achieve specific properties and tailor polyacrylamide for applications.

Horizontal centrifugal pump suitable for transporting phosphate

At ordinary times, attention should be paid to the rationality in the selection of phosphoric acid pump. The so-called reasonable selection of phosphate pump is to comprehensively consider the comprehensive technical and economic indicators such as the investment and operation cost of phosphoric acid pump unit and phosphoric acid pumping station, so as to make it in line with the principles of economy and application. The principle of acid resistance of most phosphate pumps is mainly due to the material of the pump. generally, phosphate pumps use non-metallic materials as the overflowing parts of the pump, such as "polyethylene, polypropylene, polyperfluoroethylene propylene, etc.", in which polyperfluoroethylene propylene (PVDF) is one of the good acid-resistant materials, which can basically resist the corrosion of any acid medium, so it is called plastic king.
It is necessary to meet the requirements of flow rate and head, that is, the operation point of the phosphoric acid pump (the intersection of the device characteristic curve and the performance curve of the phosphoric acid pump) is often kept in the interval, which saves power and is not easy to damage the parts.

Type selection of sodium hypochlorite dosing pump

Sodium hypochlorite, an inorganic compound with chemical formula NaClO, is a hypochlorite and is the most common "chlorine" bleach in household washing. Sodium hypochlorite is mainly used in bleaching, industrial wastewater treatment, papermaking, textile, pharmaceutical, fine chemical, sanitary disinfection and many other fields.

As one of the strong corrosion media, sodium hypochlorite pump is an important industrial raw material which is widely used. The corrosion degree of the material to the medium with different concentration and temperature is also different, so today we can choose from the following three aspects for the selection of sodium hypochlorite dosing pump:

1. The on-site working condition of sodium hypochlorite pump:
It is necessary to specify the on-site working conditions, such as the concentration of sodium hypochlorite, the working temperature, whether there are particles in the medium, as well as the flow rate and head to be satisfied in the whole work.

2. The pump structure suitable for sodium hypochlorite:
The pumps that can be used to transport sodium hypochlorite are: magnetic pump, self-priming pump, centrifugal pump, submerged pump. The specific type should be based on the concentration of sodium hypochlorite and other conditions, to choose to use self-priming pump or magnetic pump. Mabel magnetic pump without shaft seal design is completely leak-proof, but also according to the site installation environment to choose to use horizontal or vertical.

3. Material selection of sodium hypochlorite pump:
Basic plastics can be used, such as: PP, PVDF, ETFE (polytetrafluoroethylene) and other materials.

What is the difference between plastic-lined centrifugal pump and all-plastic centrifugal pump？

Plastic lined centrifugal pump and all-plastic centrifugal pump we have heard the most should be lined pump, mainly for the chemical pump flow parts and channel metal nesting, in the surface plating polytetrafluoroethylene plastic, to prevent the chemical pump due to the corrosion of the medium and damage the smoothness of the flow channel, while affecting the efficiency of the chemical pump, change the nature of the medium, The whole plastic pump is the whole pump head is made of polytetrafluoroethylene plastic casting, the plastics used in these two kinds of pumps are polytetrafluoroethylene material, which can effectively transport some acid alkaline, organic solvents, oxidants and other chemical solvents.

The common lining pump for the IHF series of corrosion resistant chemical centrifugal pump itself is suitable for negative 20℃~120℃ temperature conditions, can be a variety of concentrations of acid, alkali, oxidizing media transport, impeller and pump cover with metal insert external fluorine plastic, the pump body with metal shell lined with fluorine plastic, can withstand the weight of the pipeline while withstand mechanical impact. The shaft seal adopts external bellows mechanical seal, the static ring uses 99% alumina ceramic, and the moving ring is tetrafluoroidal filling material, which is characterized by good corrosion resistance and sealing, and does not need to disassemble the import and export pipes when the parts are replaced.

IHF centrifugal chemical pump, the pump head is made of fluorine plastic lining die, the main material is polymer material, F26 material, F46 material, fluorine plastic alloy material. Due to different materials, the price error is relatively large.

When transporting sulfuric acid, because sulfuric acid is dangerous goods, it is necessary to have a pump with strong corrosion resistance. When choosing a pump, you need to pay attention to these two points, and you can find the right pump. The pumps that transport sulfuric acid have fluorine plastic alloy centrifugal pumps, PTFE magnetic pumps, corrosion resistant self-priming pumps and other models, which can be subdivided according to flow rate and head. Many enterprises are prone to deviations in the selection of models, improper selection will bring great security risks to future production, and work efficiency will be reduced.

We must first familiarize ourselves with the characteristics of the transport medium required. As one of the strong corrosive media, sulfuric acid is an important industrial raw material with a wide range of uses. Different concentrations and temperatures of sulfuric acid on the corrosion of the material is very different, for the concentration of more than 80%, the temperature is less than 80 degrees of concentrated sulfuric acid, carbon steel and cast iron have better corrosion resistance, but it is not suitable for high-speed flow of sulfuric acid, not used as a pump material; Ordinary stainless steels such as 304 and 316 also have limited use for sulfuric acid media. The pump for conveying sulfuric acid is usually made of high-silicon cast iron and high-alloy stainless steel, but its processing is difficult and expensive, so it is not optimistic. Fluorine plastic alloys have good sulfuric acid resistance, and it has not been found that there is a chemical medium in the applicable temperature range that can react with it, so the use of fluorine lined pump (teflon) is a more economical choice. Applicable products are: fluorine plastic magnetic pump, fluorine plastic lined centrifugal pump, fluorine plastic centrifugal pump, etc.
