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.

III. Processing

Use singlescrew extruder to process, suggest to put one layer 60/80 strainer.

Thefollowing temperature(℃) profile of extruder is recommended:

Zone	Zone 1	Zone 2	Zone 3	Zone 4	Zone 5	head	Die1	Die2
Temperature ℃	140	155	160	165	170	170	170	170

Note:Above information just for you refer, please adjust it according to equipmentconditions and extruding situation.

IV. Storageand transport

Packaging：25kg/bag，Aluminumfoil vacuum and moistureproof inside bag and complex Kraft outside bag.

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

Q: Can olive nets be used for olive tree grafting?: No, olive nets cannot be used for olive tree grafting. Grafting requires specific tools and techniques to join the desired scion with the rootstock, while olive nets are used to cover the trees and protect the olives from birds or other animals.

Q: Can olive nets be used in combination with pruning tools and equipment?: Yes, olive nets can be used in combination with pruning tools and equipment. Olive nets are typically used to catch the olives as they are being pruned from the tree, ensuring that they don't fall to the ground and get damaged. The nets can be spread out under the tree while using pruning tools and equipment to collect the olives more efficiently.

Q: Can the plastic lunch box be heated by microwave oven?: Special attention should be paid to some microwave oven boxes. The box is made of No. 5 PP, but the box cover is made of No. 1 PE. Because the PE can not withstand high temperature, it can not be put into the microwave oven with the box. For insurance purposes, put the container in front of the microwave oven and remove the lid first.

Q: How do you repair the plastic surface that scratches?: Changed, want oneself grind, go buy 0 metallographic abrasive paper (polishing special), very expensive, burnish 2, 3 days can burnish

Q: How does an olive net affect the overall root development in the olive grove?: An olive net can have both positive and negative impacts on the overall root development in an olive grove. On one hand, the net provides protection from excessive sunlight and wind, which can help to retain soil moisture and prevent root dehydration. This can promote healthy root growth and development in the olive trees. On the other hand, if the net is not properly installed or maintained, it can restrict air circulation and trap excessive moisture around the roots, leading to root rot or fungal diseases. Therefore, it is important to properly install and monitor the olive net to ensure it does not negatively impact root development.

Q: What are the different types of olive nets available?: There are several types of olive nets available, including standard square mesh nets, diamond mesh nets, and knitted nets. Each type has its own unique features and benefits, such as varying mesh sizes, durability, and ease of use. It is important to choose the right type of olive net based on your specific needs and the conditions of your olive grove.

Q: How do olive nets impact the overall cost of olive production?: Olive nets can significantly impact the overall cost of olive production. These nets are used to cover olive trees during the harvest season to collect falling olives and prevent them from being damaged or lost. By using olive nets, farmers can increase their yield and reduce the amount of olives lost due to factors like wind or birds. This ultimately leads to higher production levels and increased revenues. However, the initial investment in purchasing and installing these nets can be costly, which may affect the overall cost of olive production. Nevertheless, the long-term benefits and improved efficiency provided by olive nets often outweigh the initial expenses, making them a cost-effective solution in the olive industry.

Q: Do olive nets affect the shelf life of the olives?: Yes, olive nets can affect the shelf life of olives. Olive nets are used to protect olives from pests, birds, and other external factors during the growth and ripening process. However, if not properly managed, these nets can trap moisture, which can lead to increased humidity and create a favorable environment for the growth of bacteria and mold. This can ultimately decrease the shelf life of the olives if not addressed promptly.

Q: Can olive nets be used on olive trees grown in pots indoors?: Yes, olive nets can be used on olive trees grown in pots indoors. Olive nets are typically used to protect the olives from birds and other animals when they are grown outdoors. However, if you have an olive tree in a pot indoors and you want to protect the olives, you can still use olive nets to prevent any unwanted damage.

Q: How do olive nets affect the overall antioxidant content of the olives?: Olive nets have no direct effect on the antioxidant content of the olives. The antioxidant content largely depends on the variety of the olives, the growing conditions, and the maturity of the fruit. Olive nets are primarily used to protect the olives from pests and sun damage, which indirectly helps in preserving their antioxidant content by preventing any external factors that could degrade it.
