Q: Do olive nets require any maintenance?: Yes, olive nets require regular maintenance to ensure their effectiveness. This includes removing any debris or fallen olives caught in the netting, repairing any damages or tears, and properly storing and cleaning the nets after use. Regular maintenance helps prolong the lifespan of the nets and ensures their optimal performance in harvesting olives.

Q: What is the difference between plastic PP1, PP2, PP3 and PP4?: PP1 plastic centrifuge tube is made of PP material, without toxicity and chemical tolerance. PP2 heat resistant aging. PP3- use overview: endoscope casing, left and right toolbox, door handle remarks: weathering, heat aging.

Q: Can olive nets damage the olive trees?: Yes, olive nets can potentially damage olive trees if they are not installed properly or if they are left on for too long. The nets can create extra weight on the branches, causing them to break or bend. Additionally, if the nets are not secured tightly, they can rub against the branches and trunk, leading to abrasions and potential infections. Therefore, it is important to use olive nets cautiously and remove them promptly after the harvest season.

Q: How is an olive net used in olive harvesting?: An olive net is used in olive harvesting by spreading it under the olive trees to catch the falling olives during the shaking or beating process. This helps to prevent the olives from hitting the ground and getting damaged, and allows for easier collection and separation of the olives from debris and leaves.

Q: Can olive nets be used in areas with high humidity?: Yes, olive nets can be used in areas with high humidity. The nets are designed to protect olives from birds and insects, regardless of the humidity levels in the surrounding area.

Q: How do olive nets affect the efficiency of harvesting?: Olive nets significantly enhance the efficiency of harvesting by preventing the olives from falling onto the ground or getting lost within the tree foliage. These nets create a catchment area under the trees, making it easier to collect the olives in one place. This method minimizes wastage and allows for a more systematic and streamlined harvesting process, ultimately increasing overall efficiency.

Q: What materials are olive nets typically made of?: Olive nets are typically made of lightweight and durable materials such as polyethylene or polypropylene.

Q: Can olive nets be used in areas with heavy rain?: Olive nets can be used in areas with heavy rain, but it is important to ensure proper installation and maintenance. The nets should be securely fastened and regularly inspected to prevent sagging or water accumulation. Additionally, selecting a net with appropriate drainage properties can help mitigate any potential issues caused by heavy rainfall.

Q: Is there a difference between recycled plastics and new ones?: Polyethylene: the performance of polyethylene has decreased after regeneration, the color yellow. After several extrusion, the viscosity of HDPE decreases, and the viscosity of LDPE increases.Polypropylene: when regenerated at one time, the color is almost constant, and the melt index rises. More than two times the color increased, the melt index is still rising. After regeneration, breaking strength and elongation decreased, but no problems in use.

Q: What does PPE mean in plastic products?. Polypropylene or polyethylene, for example, or something else?: Poly (phenylene oxide) (PPE) is a kind of high performance thermoplastic engineering plastics. It has excellent electrical and thermal resistance. In order to adapt to some special occasions, such as copper clad laminate industry, South Africa should be modified as thermosetting material.
