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 to reduce the risk of soil erosion in areas with high wind speeds?: Yes, olive nets can be used to reduce the risk of soil erosion in areas with high wind speeds. Olive nets are designed to cover and protect the soil from wind erosion by creating a barrier that prevents the topsoil from being carried away. They help to stabilize the soil, retain moisture, and promote healthy plant growth, thus reducing the risk of soil erosion caused by strong winds.

Q:Can I marinate salted eggs with a plastic bucket?: Lead salt antioxidant of polyvinyl chloride (PVC) products and ethanol, ether and other solvent exposure will lead precipitation. Lead salt of PVC as a food packaging and Deep-Fried Dough Sticks, fried cake, fried fish, cooked meat products, cake snacks foods to meet, will lead to molecular diffusion into the grease, so can not use PVC plastic bags containing food, especially food containing oil.

Q:What are the main defects of common plastic products?: Warpage, deformation: due to forming residual stress, shear stress, cooling stress force and uneven shrinkage caused by insufficient cooling, demoulding; bad, plastic products, insufficient strength, mold deformation and other reasons, the plastic products shape distortion and warpage from Kong Pian, such as the phenomenon of uneven wall thickness.Crack: due to plastic stress is too large, poor cooling, demoulding unevenness, poor performance of plastic or plastic products of poor design and other ills (such as deformation) and other reasons, make plastic products surface and feeding additional fine cracks, or cracking or in the load and the effect of solvent cracking phenomenon.Black spot, a plastic material or due to decomposition of combustible volatiles and air combustion decomposition under high temperature and high pressure combustion with the melt into the cavity, showing black spots, black stripes on the surface of plastic products, plastic products, or along the surface is like carbon burn phenomenon.

Q:Do olive nets affect the quality of harvested olives?: Yes, olive nets can affect the quality of harvested olives. When used properly, olive nets can prevent olives from falling on the ground and getting damaged, which helps maintain their quality. However, if the nets are not installed or handled correctly, they can cause bruising or puncturing of the olives, leading to a decrease in quality. Therefore, proper installation and careful handling of olive nets are crucial in maintaining the quality of harvested olives.

Q:Are there any specific techniques for preventing olive net damage from heavy rainfall?: Yes, there are specific techniques for preventing olive net damage from heavy rainfall. Some effective techniques include installing gutter systems to divert rainwater away from the olive trees, using raised beds or mounds to improve drainage, ensuring proper spacing between trees to allow airflow and reduce the risk of water pooling, and using mulch or ground cover to absorb excess water. Additionally, regularly inspecting and maintaining the olive netting and replacing damaged or weak parts can help prevent water accumulation and minimize damage caused by heavy rainfall.

Q:How do olive nets prevent damage from insect infestations?: Olive nets prevent damage from insect infestations by creating a physical barrier that prevents insects from reaching the olive trees and laying eggs or feeding on the fruit. The fine mesh of the nets blocks insects from entering the trees and provides protection against pests such as olive fruit flies, which can cause significant damage to the crop.

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 are designed to protect the olives from being damaged or lost due to wind or birds. They can be easily adjusted to fit trees of different heights, making them suitable for trees with a low height as well.

Q:Is plastic bath safe?: If you're sure, try it directly and see if any chemicals are poisonous. Don't worry about that. You don't have to drink it. Although some plastics break down toxic substances when heated, it's in high temperature

Q:Do olive nets damage the olive tree?: No, olive nets do not damage the olive tree.

Q:Are there any specific guidelines for using olive nets on old or mature olive trees?: Yes, there are specific guidelines for using olive nets on old or mature olive trees. It is important to ensure that the netting is properly secured to prevent damage to the branches and fruits. Additionally, the netting should be installed when the olives are close to ripening to effectively catch them during harvest. Regular inspection and maintenance of the netting is also recommended to address any potential issues and ensure its effectiveness.
