Step 2: Prepare the surface

Prepare the surface you will be bonding by ensuring it is clean and free from dust, dirt, and oil. Use a clean cloth or sponge to wipe the surface and remove any contaminants. This will ensure a strong and durable bond.

Step 3: Mix the adhesive

For best results, follow the manufacturer’s instructions to prepare the adhesive. Usually, this involves mixing the adhesive with water in a specific ratio. Use a mixing container and carefully measure the amount of adhesive and water as directed.

Step 4: Apply the adhesive

Using a brush or a trowel, apply a thin, even layer of the adhesive to one of the surfaces you wish to bond. Make sure to spread the adhesive evenly to ensure a solid bond. Avoid applying too much adhesive as it can lead to messiness and compromised results.

Step 5: Join the surfaces

Once the adhesive is applied, carefully align the two surfaces together and firmly press them together. Apply even pressure across the entire area to ensure a strong bond. If needed, use clamps or weights to hold the surfaces in place while the adhesive dries.

Step 6: Allow drying time

Depending on the type of adhesive and the materials being bonded, the drying time can vary. It is important to be patient and allow sufficient drying time for the adhesive to set properly. Refer to the manufacturer’s instructions for the recommended drying time.

Step 7: Clean up

After completing the bonding process, clean up any excess adhesive using a damp cloth or sponge. It is easier to remove the adhesive while it’s still wet, so make sure to clean up promptly.

And there you have it! By following these step-by-step instructions, you can effectively use PVA 088-03 & PVA 0388 for your bonding needs. Remember to always refer to the manufacturer’s guidelines and recommendations for best results.

Why can polyacrylamide improve oil recovery efficiency?

2024-09-23

Polyacrylamide, a water-soluble polymer, can improve oil recovery efficiency through a process known as enhanced oil recovery (EOR). There are several mechanisms by which polyacrylamide achieves this:

1. Viscosity Modification: Polyacrylamide can increase the viscosity of the water injected into oil reservoirs. This increased viscosity helps to improve the sweep efficiency by reducing the mobility of the injected water. The higher viscosity enables the injected water to displace oil more effectively, pushing it towards production wells and enhancing oil recovery.

2. Water Channeling Control: Polyacrylamide can control the permeability of the reservoir, particularly in highly permeable zones. By reducing the permeability of certain porous formations, polyacrylamide helps to divert the injected water flow away from the high-permeability channels (water fingers) and into the unswept areas of the reservoir. This way, it ensures more uniform and efficient displacement of oil.

3. Conformance Control: In some cases, oil reservoirs have heterogeneities or fractures that can cause water to bypass the targeted oil-bearing zones. Polyacrylamide can be injected to plug these high-permeability paths and divert the injected water into the desired areas. This technique is known as conformance control and helps improve overall oil recovery.

4. Clay Stabilization: Polyacrylamide can also act as a clay stabilizer. It prevents the swelling and migration of clays present in the reservoir, which could otherwise cause formation damage and reduce the permeability of the reservoir. By stabilizing the clay particles, polyacrylamide maintains the permeability of the reservoir and enhances oil recovery.

Overall, the addition of polyacrylamide as part of an EOR process helps to improve the mobility control of the injected water, reduce bypassing of oil, and maintain reservoir permeability. These factors contribute to increased oil recovery efficiency. It's worth noting that the effectiveness of polyacrylamide in enhancing oil recovery depends on various reservoir characteristics, such as reservoir type, oil properties, and injection strategies, which must be carefully considered during the planning and implementation of EOR projects

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.
