Everyone knows about iron wire and steel wire, but I am afraid that many people still don't know about polyester line. With the development of high technology, knowledge is updated faster and faster, and information technology is also developing rapidly. Therefore, iron wire and steel wire will also be replaced by new products.

polyester line is a new type of product that is resistant to high and low temperatures, acid and alkali, aging and radiation, which is better than iron wire in all aspects. This new product is called polyester line, also called PET polyester line. Everyone knows that iron wire and steel wire are heavy and inconvenient to carry, but polyester line and polyester line are relatively light, with a total weight of one tenth of steel wire and iron wire, and it is relatively simple to operate and handle.

Iron wire will expand and contract with changes in temperature, and thermal expansion and contraction are obvious, so the performance is poor. In this case, the length of the iron wire needs to be increased, or the iron wire needs to be tightened. At the same time, the iron wire is easy to conduct electricity. In the case of lightning, it may burn the plastic film or cause certain harm to people. polyester line will not change with changes in temperature, and maintain its original performance and original state, because it is a carbon-containing polyester compound, so it is not conductive. In large greenhouse production bases, loose wire is dangerous to machines and will cause expensive machines to be scrapped. Existing machines can be used to straighten polyester line tightly without damaging the machine.

Iron wire will be easily corroded after a long time of use, while polyester line polyester line will not be corroded. Rusting of iron wire is an insurmountable problem. Rusted iron wire will affect the service life of plastic film and shorten the life of iron wire. polyester line polyester line will not rust and has a service life of up to ten years. Iron wire steel wire requires manpower and material resources to tighten the iron wire once a year. polyester line polyester line does not require manpower and material resources to tighten the polyester line polyester line. The weight and hardness of iron wire make it difficult to install and adjust.

polyester line polyester line is light and easy to bend, so it is easy to install. Iron wire is difficult to repair after corrosion and breakage. polyester line polyester line does not break and has strong pulling force. The above is a clear contrast between plastic-steel wire and polyester line and iron wire and steel wire. Plastic-steel wire and polyester line have low price, excellent quality, environmental protection, and are easy to use. The characteristics of plastic-steel wire and polyester line can completely replace the use of iron wire and steel wire.
