Q:
No, olive nets are not effective against larger animals like deer or rabbits.
Q:
Yes, olive nets can be used to reduce labor costs in olive harvesting. These nets are spread on the ground beneath the olive trees to catch the falling olives during the harvesting process. By using olive nets, manual labor requirements such as handpicking or using mechanized harvesters can be reduced or eliminated, resulting in cost savings.
Q:
Yes, olive nets can be used in regions with high disease pressure. Olive nets are primarily used to protect the olives from birds and other animals, but they also provide some protection against certain diseases. However, it is important to note that olive nets alone may not provide complete protection against all diseases, and additional measures may be required to effectively combat high disease pressure in olive-growing regions.
Q:Is plastic bath safe?
Plastic is made of resin and additives, general plastic is not toxic safety and health, just do not know what he added additive modifier additives, like life is half made of polyethylene and polypropylene plastic and so on, are c h, non-toxic. Pro, bath bucket is absolutely safe to use.
Q:
Olive nets are highly effective in catching falling olives. They create a protective barrier beneath the olive trees, preventing the olives from hitting the ground and potentially getting damaged. The nets also make the harvesting process more efficient as the olives can be easily collected from the nets without having to search for them on the ground.
Q:
Yes, olive nets can be used in olive groves with limited access for machinery. Olive nets are lightweight and easy to install manually, making them suitable for groves where machinery cannot easily navigate. These nets can be manually spread across the trees to collect falling olives during harvest, providing an efficient solution for groves with limited machinery access.
Q:How do plastics weld?
Plastic welding is limited to thermoplastic welding because only thermoplastics can be melted or softened while they are heated, while thermosetting plastics cannot be softened and remelted while they are heated.Hot air welding oxyacetylene similar to metal, but the latter with the former fire hot air heating. Hot gas welding process, the welding torch from the hot gas stream (typically 200 to 300 degrees Celsius temperature, flow rate of 15 ~ 60L/min) and the filler rod and welding pieces of the heating surface, when the material softening reached sticky state, filling rod continuous pressure into the weld. The filling bar material is the same as that of the base metal, usually round (about 3mm in diameter), and is welded by multiple bead welding. One drawback of the round filling rod is that the hollow bubbles are easily entrapped in the weld during the multi pass process, resulting in lower strength. This problem can be solved by using a triangular section welded rod. Typical materials for hot air welding include polyvinyl chloride, polyethylene, polypropylene, plexiglass, polycarbonate, POM, polystyrene, nylon, ABS and so on. The main advantage of hot gas welding is adaptive (flexibility), portable equipment and processing of large, complex parts can be simple. Hot air welding is suitable for irregular structures, but it is slow and the quality of welding depends largely on the skill of the operator. Therefore, it is seldom used in mass production, but it is suitable for repair operation.
Q:
Yes, olive nets are designed to be resistant to various weather conditions. They are typically made of durable and weatherproof materials that can withstand exposure to sunlight, rain, wind, and other environmental elements. This allows olive nets to provide effective protection for olive trees and fruits during different weather conditions.
Q:
Yes, olive nets do require special installation techniques for densely planted groves. In order to effectively protect the olives from birds and other pests, the nets need to be installed tightly and securely to cover the entire grove. This may involve using additional support structures like poles or wires to ensure the nets are properly suspended above the trees. Additionally, it is important to consider the spacing and positioning of the trees to ensure that the nets can be installed and removed easily without causing damage to the plants or the nets themselves.
Q:
Yes, olive nets can be used in regions with frequent rainfalls. Olive nets are designed to protect the olives from various elements, including rain. They are made from durable and waterproof materials that prevent water from penetrating through, ensuring the olives remain safe and unaffected by the rainfall.
