Hey there! As a supplier of Polyanionic Cellulose PAC DHV, I often get asked about its shelf life. In this blog, I'll dig deep into this topic and share some cool info with you.
First off, let's quickly understand what Polyanionic Cellulose PAC DHV is. It's a high - performance additive mainly used in the oil and gas drilling industry. It helps in controlling the viscosity of drilling fluids, reducing fluid loss, and improving the overall stability of the drilling process. It's got some pretty awesome properties, which is why it's so popular among drillers.
Now, onto the main question: what's the shelf life of Polyanionic Cellulose PAC DHV? Well, generally speaking, under proper storage conditions, the shelf life of Polyanionic Cellulose PAC DHV is around 2 years. But hey, that's not set in stone, and there are a bunch of factors that can affect it.
Factors Affecting Shelf Life
Storage Temperature
Temperature plays a huge role. PAC DHV should be stored in a cool and dry place. High temperatures can cause the product to degrade faster. If it's stored in an area where the temperature is constantly above 30°C (86°F), the chemical structure of PAC DHV might start to change. This can lead to a decrease in its performance, like reduced viscosity - building ability and less effective fluid - loss control.
On the other hand, extremely low temperatures aren't great either. Freezing temperatures can cause the product to solidify or form lumps, which will make it difficult to use and can also damage its properties. So, ideally, the storage temperature should be between 10°C - 25°C (50°F - 77°F).
Humidity
Humidity is another biggie. PAC DHV is a hygroscopic material, which means it can absorb moisture from the air. If the storage environment is too humid, the product can clump together. Once it clumps, it becomes hard to disperse in the drilling fluid, and its performance can be seriously affected. To avoid this, it's important to store PAC DHV in a place with a relative humidity of less than 60%. You might even consider using desiccants in the storage area to keep the moisture levels down.
Packaging
The type of packaging also matters. Good - quality, sealed packaging can protect PAC DHV from external factors like moisture, air, and dust. Most of the time, we supply PAC DHV in multi - layer paper bags with a plastic liner inside. This kind of packaging provides a good barrier against moisture and air. But if the packaging gets damaged during transportation or storage, it can expose the product to the elements and shorten its shelf life.
How to Check if PAC DHV is Still Good
If you're not sure whether your PAC DHV is still within its usable lifespan, there are a few things you can do. First, take a look at its physical appearance. If it has clumped together, changed color, or has an unusual smell, it might be a sign that it's starting to degrade.
You can also do a simple performance test. Mix a small amount of the PAC DHV with water or a test fluid and check its viscosity. Compare the results with the specifications provided. If the viscosity is significantly lower than expected, it could mean that the product has lost its effectiveness.
Other Related Products
We also offer other types of Polyanionic Cellulose, such as Polyanionic Cellulose PAC DLV, Polyanionic Cellulose PAC LV, and Polyanionic Cellulose PAC HV. Each of these products has its own unique properties and applications. PAC DLV is great for low - viscosity requirements, PAC LV is suitable for general - purpose drilling fluids, and PAC HV is used when high - viscosity is needed.
Importance of Using Fresh PAC DHV
Using fresh PAC DHV is crucial for the success of your drilling operations. A degraded product won't perform as well, which can lead to problems like increased fluid loss, poor hole stability, and even equipment damage. By using a product within its shelf life, you can ensure that you're getting the best performance and the most value for your money.
