Q: Can olive nets be used for olive oil production?: Yes, olive nets can be used for olive oil production. Olive nets are commonly used during the olive harvesting process. They are spread under the olive trees to catch the falling olives, preventing them from being damaged upon contact with the ground. Once the olives are collected, they can be taken to the oil mill for pressing and extraction, resulting in the production of olive oil.

Q: How do olive nets improve the efficiency of olive harvesting?: Olive nets improve the efficiency of olive harvesting by providing a convenient and effective method of collecting the olives. These nets are spread under the olive trees, allowing the ripe olives to fall directly onto the net instead of scattering on the ground. This not only prevents the loss of olives but also saves time and effort that would otherwise be spent searching for and picking up individual olives. The nets make it easier to gather a larger quantity of olives in a shorter period, enhancing the overall efficiency of the harvesting process.

Q: Can olive nets be used on trees of different ages?: Yes, olive nets can be used on trees of different ages. Olive nets are versatile and can be used on both young and mature olive trees to protect the harvested olives from falling to the ground.

Q: What's the difference between memory plastic and sheet metal?: On the market, memory plates, glasses and more refers to the selection of TR90 material framework, collision extrusion generally will not be deformed, but afraid of exposure to some chemical agents, like alcohol, as little exposure.

Q: Can olive nets be used in combination with harvesting machinery?: Yes, olive nets can be used in combination with harvesting machinery. Olive nets are often spread under olive trees to catch the falling olives during mechanical harvesting. This allows for easier collection and reduces damage to the olives.

Q: Can olive nets be used in olive groves with limited space for storage?: Yes, olive nets can be used in olive groves with limited space for storage. Olive nets are lightweight and flexible, making them easy to install and remove as needed. They can be folded or rolled up for compact storage, allowing olive grove owners with limited space to store them conveniently.

Q: Can olive nets be used for olive tree water conservation?: No, olive nets are typically used for harvesting olives and protecting them from pests. They are not designed for water conservation purposes.

Q: Are olive nets resistant to pests or insects?: Yes, olive nets are generally resistant to pests and insects as they are designed to protect olive trees and fruits from being damaged or consumed by insects and pests.

Q: Types and uses of agricultural plastic products: Since the production of agricultural plastic film, China has made two first in the world, that is, production first and covering area first. It is roughly 1.6 times as much as other countries in the world. According to incomplete statistics, at present the whole industry with the production of plastic sheeting 1000 enterprises, production capacity of 2 million tons, one million tons of annual production capacity of about 60 enterprises, large-scale backbone enterprises around 30, its production capacity and annual output accounted for 60% of the total. Film in consumption has reached 700 thousand tons, covering an area of 50 million acres; film annual sales of about 450 thousand tons, covering an area of 220 million acres or more; the actual consumption of agricultural film has more than 1 million 200 thousand tons.

Q: How to make plastic shrink?: The factors affecting the shrinkage of plastics include: plastic varieties, molding conditions, mold structure and so on. The shrinkage rates of different polymers are different. Secondly, the shrinkage of plastic is closely related to the shape of plastic parts, the complexity of internal structure, and whether there are inserts or not.
