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 plastic bottles be recycled?: Plastic materials used in supermarkets and shopping malls before the high temperature resistance, plastic bottle manufacturer 2 stands for HDPE HDPE). But not easy to clean, easy to breed bacteria; encountered high temperature and grease easily precipitate; 3 represents PVC polyvinyl chloride, in which plasticizers contain harmful substances. At present, there are a lot of plasticizer in Europe has banned the country less for plastic food packaging use; heat resistance is not strong, 4 on behalf of LDPE low density polyethylene) currently on the market, plastic film, plastic film mostly with this material. Qualified PE cling film will appear hot when it is over 110 degrees centigrade. Wrap food with plastic wrap to heat it. The grease in plastic bottle can dissolve the harmful substances in the preservative film easily;

Q: Can olive nets be customized for specific orchard requirements?: Yes, olive nets can be customized to meet specific orchard requirements. These nets can be tailored in terms of size, shape, and material to ensure optimal coverage and protection for olive trees in different orchards. Customization allows for better adaptation to specific orchard layouts, tree sizes, and climatic conditions, ultimately enhancing the effectiveness and efficiency of olive tree cultivation.

Q: Can olive nets be used in regions with sandy or rocky soils?: Yes, olive nets can be used in regions with sandy or rocky soils. These nets are designed to be versatile and can be set up in various terrains, including sandy or rocky areas. They are commonly used to collect olives during harvest season, regardless of the soil type.

Q: How do olive nets prevent damage from diseases transmitted by insects?: Olive nets prevent damage from diseases transmitted by insects by acting as a physical barrier, preventing insects from coming into contact with the olive trees. This prevents the transmission of diseases as the insects are unable to land on the trees and spread the pathogens.

Q: Can olive nets be used for olive tree protection from animals?: Yes, olive nets can be used for olive tree protection from animals. These nets are specifically designed to prevent animals, such as birds and rodents, from accessing the olive fruits. The nets are placed over the trees, creating a physical barrier that deters animals from reaching the olives, ensuring their protection.

Q: How do I store olive nets when not in use?: When not in use, it is recommended to store olive nets in a clean and dry area. Fold the nets neatly and ensure they are free from any dirt or debris. You can store them in a container or a bag to protect them from dust and pests. Properly labeling the container or bag can also help in easy identification and retrieval when needed again.

Q: Can olive nets be used in combination with frost protection methods?: Yes, olive nets can be used in combination with frost protection methods. Olive nets are primarily used to protect olive trees from birds and other pests, but they can also provide some level of frost protection by acting as a barrier against cold winds and reducing heat loss from the trees. However, for effective frost protection, additional methods such as using frost blankets, heaters, or irrigation systems may be necessary.

Q: How are olive nets cleaned after use?: Olive nets are typically cleaned after use by first removing any debris or leaves from the nets. Then, they are washed using water and mild detergent to remove dirt and stains. Finally, the nets are dried thoroughly before being stored for future use.

Q: How do olive nets prevent damage from strong sunlight?: Olive nets prevent damage from strong sunlight by providing shade and reducing the direct exposure of the olive trees to the intense rays of the sun. This helps to regulate the temperature and moisture levels around the trees, minimizing the risk of sunburn and dehydration. Additionally, the nets act as a barrier, blocking harmful ultraviolet (UV) rays that can cause damage to the leaves and fruits.

Q: How many kinds of plastics are there?: Name: ABS engineering plastics, can be used for connecting piece, seat back, seat board, it is able to perform plastic electroplating (water plating) the main raw material.PP: the name for polypropylene, five-star pin, handrails, floor mats and high strength is not necessary connections. Disadvantages: poor wear resistance and low surface hardness.PVC Name: PVC, mainly used for sealing, inserted conditions. It is adapted to extrusion molding, and PVC material is the material does not burn plastic parts, processing temperature stability, especially the stability of the color is not good.
