It has very good performance of resistance to electricity mark, andexcellent electrical properties, weatherability, tenacity, abrasive resistanceand excellent resistance to environmental stress crack. Meeting DL/T 788-2001standard.

ⅲ、Processing

The NDPE compound suits to process with extruder which L/D is 25 orabove 25. And it should be dried before using, the temperature is 90℃.

the following temperature(℃) profile of extruder is recommended:

Zone	1 Zone	2 Zone	3 Zone	4 Zone	Head	Die
Temperature	185	215	220	240	245	250

Note: The processing parameters are for reference only, optimalconditions may vary according to the equipment used. The cooling water tankshould be used sectionally cooling with warm-water echelon in order to reduceinternal stress.

ⅳ、Storage andtransport

Packaging：25kg/bag， PE membrane inside bag and Kraft outside bag.

Storage and transport: Avoiding in direct sunlight and weathering.The storage place should be in clean, cool, dry, and ventilated conditions.

Q: Can olive nets be used in organic olive oil production?: Yes, olive nets can be used in organic olive oil production. Olive nets are commonly used in organic farming practices as a means to collect olives during the harvest. They are placed under olive trees to catch the falling fruits, ensuring that they do not touch the ground and remain free from contaminants. This method helps maintain the organic integrity of the olives, which is crucial for organic olive oil production.

Q: Do olive nets affect the overall appearance of the olive tree orchard?: Yes, olive nets do affect the overall appearance of the olive tree orchard. When olive nets are placed over the trees to protect the fruit from birds or to collect falling olives, they can alter the aesthetic appeal of the orchard. The nets create a visible barrier that can be seen from a distance and may obscure the natural shape and foliage of the olive trees.

Q: How do olive nets prevent olives from being damaged by sunscald?: Olive nets prevent olives from being damaged by sunscald by providing shade and protection from direct exposure to the sun's intense heat and harmful UV rays.

Q: Are olive nets easy to repair if damaged?: Yes, olive nets are generally easy to repair if damaged. They are made from durable materials such as polyethylene or nylon, which can withstand wear and tear. In case of small tears or holes, they can be easily patched up with repair kits or by stitching them together. However, if the damage is extensive or beyond repair, it may be more cost-effective to replace the net entirely.

Q: What is the average cost of an olive net?: The average cost of an olive net can vary depending on the size, material, and quality, but it typically ranges from $50 to $200.

Q: Can olive nets be used in combination with other types of insect control methods?: Yes, olive nets can be used in combination with other types of insect control methods. Olive nets are primarily used to protect olive trees from insects, but they can be complemented with additional measures such as insecticides, pheromone traps, or biological controls to enhance the effectiveness of pest management.

Q: Can olive nets be used in regions with high humidity levels?: Yes, olive nets can be used in regions with high humidity levels. Olive nets are typically made of strong, durable materials that can withstand various weather conditions, including high humidity. However, it is important to ensure proper airflow and ventilation to prevent the growth of mold and mildew on the olives due to the moisture in the air. Monitoring and maintaining optimal conditions during olive harvesting and storage are crucial for preserving the quality of the olives in regions with high humidity levels.

Q: Plastic shoes taste great, is it harmful?: But if the smell of plastic shoes is too strong and smells long, there will be smoke and dizziness, which is likely to contain substances harmful to human body.

Q: Are there any specific safety precautions to be followed while using olive nets?: Yes, there are specific safety precautions to be followed while using olive nets. It is important to wear appropriate protective gear, such as gloves and safety goggles, to avoid any potential injuries. Additionally, make sure the olive nets are securely fastened and properly installed to prevent accidents or falls. Always be cautious while working on elevated surfaces and avoid placing the nets near power lines. Regular maintenance and inspection of the nets are also necessary to ensure their effectiveness and prevent any potential hazards.

Q: Can olive nets be used for both small and large-scale olive oil production?: Yes, olive nets can be used for both small and large-scale olive oil production. Olive nets are commonly used in the olive industry to collect olives efficiently during the harvesting process. They can be used in small-scale operations where olives are hand-picked and in large-scale operations where mechanical harvesters are employed. The nets help prevent olives from falling to the ground, reducing potential damage and contamination. Overall, olive nets are versatile tools that can be effectively utilized in various olive oil production settings.
