II. ProductDescription
Theseproducts used PVC resin as base materials, and added nanometer conductivecarbon black as filling, by mixing, plasticizing, pelleting, and finished aspellets. These products have very good conductive and processingcharacteristics. And it mainly substituted the graphite coat structure.
In theformula, it decreased the affect of plasticizer to conductive carbon black bythe technology of toughness reinforcing. At the same time, reduced the affectof materials low temperature and processing properties, because adding masscarbon black in the products. And we selected suitable low temperatureadditiver and rheological agent to improve the PVC materials, and made it hasgood integrated properties.

- Q: What is the difference between plastic raw materials and engineering plastics?
- Plastic is resin and filler, so it is usually granular. Raw materials too. Only a few powdery.
- Q: Can olive nets be used on trees with a low height?
- Yes, olive nets can be used on trees with a low height. Olive nets can be easily adjusted and positioned to fit trees of various heights, making them suitable for use on trees with a low height.
- Q: How long does an olive net last?
- The lifespan of an olive net can vary depending on various factors such as the quality of the net, its maintenance, and the frequency of use. On average, a well-maintained olive net can last for several years, ensuring efficient harvests season after season.
- Q: Are there any disadvantages of using olive nets?
- Yes, there are a few disadvantages of using olive nets. 1. Damage to trees: Olive nets can cause damage to the limbs and branches of olive trees if not properly installed or removed. This can lead to decreased productivity or even the death of the tree. 2. Labor-intensive: Installing and removing olive nets can be a labor-intensive process, especially in larger orchards. It requires manpower and time to properly secure the nets, which can increase production costs. 3. Risk of contamination: Olive nets can accumulate dirt, debris, and bird droppings, which may contaminate the olives during harvesting. This can affect the quality and marketability of the final product. 4. Impacts on biodiversity: Olive nets can disrupt the natural habitat of beneficial insects and birds that play a crucial role in pollination and pest control. This can have adverse effects on the overall biodiversity of the orchard ecosystem. 5. Limited use in windy conditions: Olive nets are not suitable for areas with high winds, as they can easily get damaged or blown away. This restricts their use in regions prone to strong winds, limiting their effectiveness. Despite these disadvantages, proper installation, regular maintenance, and careful harvesting techniques can help minimize these issues and maximize the benefits of using olive nets.
- Q: Can olive nets be custom-made?
- Yes, olive nets can be custom-made to suit specific sizes and requirements.
- Q: How does an olive net help prevent damage to the olives during harvesting?
- An olive net helps prevent damage to the olives during harvesting by creating a protective barrier that catches the falling olives. This prevents them from hitting the ground and potentially getting bruised or damaged.
- Q: Are there any specific techniques for training olive tree branches when using olive nets?
- Yes, there are specific techniques for training olive tree branches when using olive nets. One common technique is called "hedging and topping," where the branches are pruned to maintain a specific height and shape that facilitates the use of olive nets. This helps in ensuring that the net can be easily placed and removed without damaging the branches or the tree. Additionally, some olive farmers also use techniques like tying or staking the branches to keep them in a desired position while the nets are in place. Overall, careful pruning and strategic branch management are crucial for effective training when using olive nets.
- Q: How do olive nets prevent olives from falling to the ground?
- Olive nets are designed to cover the olive trees and create a barrier that prevents olives from falling to the ground. The nets are spread over the tree canopy, catching the olives as they ripen and detach from the branches. This helps in collecting the olives intact, ensuring minimal loss and damage during harvesting.
- Q: How do you protect young olive trees with olive nets?
- To protect young olive trees with olive nets, you can start by carefully draping the netting over the tree, ensuring that it covers the entire canopy. Secure the netting at the bottom, making sure it is tightly fastened to prevent any gaps or openings. This will create a barrier that keeps birds, insects, and other potential threats away from the tree. Regularly inspect the netting to ensure there are no tears or holes that may compromise its effectiveness. Additionally, ensure the netting is elevated enough to avoid contact with the tree branches, as this can damage the delicate foliage. By properly installing and maintaining the olive nets, you can safeguard your young olive trees from various hazards and promote healthy growth.
- Q: Are there any specific techniques for preventing olive net damage from strong winds?
- Yes, there are several techniques for preventing olive net damage from strong winds. One effective technique is to use a double anchoring system, where the nets are securely attached to the ground with multiple anchor points. This helps distribute the force of the wind and prevents the nets from being blown away or torn. Additionally, installing windbreaks or wind fences around the olive orchard can help reduce wind speed and protect the nets. Another technique is to regularly inspect and maintain the nets, repairing any small tears or weak spots to prevent further damage.
