Physical properties of polyvinyl alcohol

2024-09-20

Polyvinyl alcohol, an organic polymer. The molecular formula of polyvinyl alcohol is (C₂H₄O), the degree of polymerization is usually 500 to 5000, and the molecular weight is usually 25000 to 300000. Polyvinyl alcohol at room temperature is a colorless, white or milky white amorphous powder, odorless and tasteless, but it decomposes Can produce irritating smoke and dust.

The physical properties of polyvinyl alcohol change with the degree of polymerization and alcoholysis. Generally, the density range is 1.19-1.31g/cm³, the melting point is 212-267°C, and the boiling point under standard atmospheric pressure is about 340°C. Polyvinyl alcohol is soluble in hot water, insoluble in gasoline, benzyl alcohol ketone and other general organic solvents, soluble in hot hydroxyl organic solvents (such as glycol, glycerin, phenol, etc.), and soluble in liquid at room temperature. Ammonia and dimethyl sulfoxide.

The chemical structure of polyvinyl alcohol is stable, but alcohol-related reactions can also occur based on its molecular structure. For example, polyvinyl alcohol can undergo esterification reactions with inorganic complexes and organic compounds, and acetalization reactions with various aldehydes.

Polyvinyl alcohol is produced differently from other polymers and cannot rely on the polymerization of single unit precursor monomers. Industrially, polyvinyl acetate is usually produced by polymerizing vinyl acetate, and then polyvinyl alcohol is produced by alcoholysis under alkaline conditions.

Principle of redispersible emulsion powder

2024-09-20

Modification of inorganic cementitious materials such as cement with polymer emulsion has been widely used. Since the water in the emulsion will immediately react with the cement after mixing the two and finally solidify, a two-component form is used in most cases. , measure and mix each component in proportion at the construction site. This brings inconvenience to the storage, transportation and construction of materials. The emergence of re-dispersible emulsion powder has changed the above phenomenon. Redispersible latex powder is a micron-sized thermoplastic resin powder obtained by spray-drying a polymer emulsion to remove water. It can be reduced to an emulsion after adding water.Due to this characteristic, it is widely used in single-component JS waterproof coatings, polystyrene board bonding mortars for building insulation, flexible surface protection mortars, polystyrene particle insulation coatings, ceramic tile adhesives, self-leveling mortars, dry-mix mortars, etc. It is widely used in fields that require modification of inorganic cementitious materials.

RDP is a polymer powder produced by spray drying of polymer emulsion. Polymer emulsions are mostly oil-in-water systems in which thermoplastic polymers with a solid content of about 50% are evenly distributed in water with fine particles (0.1-10 μm). After losing water, the polymer particles first form dense spheres and accumulate on the surface. Under the action of energy, discrete polymer particles form a continuous polymer body. To produce redispersible latex powder by the spray drying method, a layer of PVA protective film is added to the surface of the polymer in advance. Due to the existence of the protective film, the dry powders cannot merge. In order to prevent the rubber powder from agglomerating, some fine mineral powders are also added. , such as clay, etc. However, when redispersible latex powder is mixed with alkaline substances such as cement and water, the PVA will be saponified and adsorbed by the quartz in the sand and removed. The rubber powder that has lost its protective film can eventually form a continuous water-insoluble polymer. membrane.

The particle size of the rubber powder (5-250 μm) is much larger than the particle size of the polymer dispersed phase in the emulsion (0.1-10 μm), indicating that the latex particles will agglomerate during the spray drying process. In order to reduce the tendency of polymer powder to agglomerate during long-term storage, inert fluid materials such as clay, talc, silica and other fine particles are usually added to the dry powder as anti-stick fillers. The filler is determined according to the type of polymer and its glass transition temperature. The dosage is generally 8%-30% of the dry polymer powder, which is the main source of ash in redispersible latex powder. After redispersible latex powder is redispersed, the diameter of the latex particles becomes about (0.1-10μm).

How to detect the dissolution time of polyacrylamide?

2024-09-20

To test the dissolution time of polyacrylamide (PAM), you can follow these steps:

1. Prepare a known volume of water or the solvent in which you plan to dissolve the PAM. It's important to measure the volume accurately for consistent results.

2. Heat the water or the solvent to a specific temperature, if required. Some PAM formulations might require elevated temperatures for efficient dissolution. Check the specifications or guidelines for the particular PAM you are using.

3. Slowly add the PAM powder to the water or solvent while stirring continuously. The stirring can be done manually using a glass rod or by using a magnetic stirrer.

4. Observe the PAM powder as it dissolves in the solution. Note the time it takes for the PAM to completely dissolve. You can consider it dissolved when there are no visible clumps or particles remaining.

5. Repeat the experiment multiple times to ensure consistency and accuracy. Take note of any variations in the dissolution time and average the results for better reliability.

It's worth mentioning that the dissolution time can be affected by various factors such as temperature, concentration of the PAM solution, and the specific formulation of the PAM. Therefore, it's crucial to maintain consistent experimental conditions when comparing different samples or performing subsequent.

How to detect the solid content of polyacrylamide?

2024-09-14

To detect the solid content of polyacrylamide, you can follow the steps below:

1. Weigh an empty, clean, and dry container or crucible accurately and record its weight (W1).

2. Add a known amount of polyacrylamide sample to the container.

3. Place the container with the sample in an oven set to a specific temperature (usually around 105-110°C) for a specific time (typically 1-2 hours). The aim is to evaporate the moisture and volatile components from the polyacrylamide.

4. After the specified time, remove the container from the oven and allow it to cool in a desiccator.

5. Once the container has reached room temperature, weigh it with the dried sample and record its weight (W2).

6. Calculate the solid content using the formula:

Solid Content (%) = [(W2 - W1) / (W2 - container weight)] × 100

Where:

- W1 is the weight of the empty container.

- W2 is the weight of the container with the dried polyacrylamide sample.

- The container weight is the weight of the container itself, which should be subtracted to obtain the net weight of the dried sample.

This method provides an estimation of the solid content of polyacrylamide based on the weight loss after drying. Keep in mind that the drying conditions and time can vary depending on the specific requirements of polyacrylamide and the application for which it will be used.
