为什么塑钢线可以替代钢丝，铁丝？ Why can plastic steel wire replace steel wire and iron wire?

　　提起铁丝钢丝无人不知无人不晓，但是提起塑钢线恐怕当前还有很多人不知道吧。随着高科技的发展，知识更新越来越快，信息技术也也飞速发展。所以铁丝钢丝也会被新的产品所替代。

　　塑钢线就是一种各项性能都比铁丝出色的一种耐高低温、耐酸碱、抗老化、抗辐射的一种新型产品。这种新型产品叫塑钢线也叫PET聚酯线。铁丝钢丝大家都知道重量重，携带不方便，但是塑钢线聚酯线则比较轻总重量是钢丝铁丝的十分之一，操作处理起来比较简单。

No one knows about lifting iron wire, but I'm afraid many people don't know about lifting plastic steel wire at present. 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.

Plastic steel wire is a new type of product that has better properties than iron wire, such as high and low temperature resistance, acid and alkali resistance, aging resistance and radiation resistance. This new product is called plastic steel wire or PET polyester wire. As we all know, iron wire and steel wire are heavy and inconvenient to carry, but plastic steel wire and polyester wire are relatively light. The total weight is one tenth of that of steel wire and steel wire, and the operation is relatively simple.

　　铁丝会随着气温的变化而伸缩，热胀冷缩明显，因此持久性差，这种情况下需要增加铁丝的长度，或者拉紧铁丝，同时铁丝容易导电，有雷电的情况下可能会烧毁塑料薄膜，或者对人造成一定的伤害。塑钢线不会随着温度的变化而变话，永久保持原性能原状态，因为它是含碳的聚酯化合物，因此不导电。在大型的温室大棚生产基地，松弛的铁丝对机器有危险，会使昂贵的机器报废。现有的机器都可以适用于塑钢线紧紧的拉直，不会有损于机器。

　　铁丝使用时间久了会容易被腐蚀，而塑钢线聚酯线不会被腐蚀，铁丝生锈是一个无法克服的问题，生锈的铁丝会影响塑料薄膜的使用寿命，而且会使铁丝的寿命缩短。塑钢线聚酯线不会生锈，使用寿命长达十年。铁丝钢丝每年要投入一次人力和物力来拉紧铁丝。塑钢线聚酯线无须人力和物力的投入来拉紧塑钢线聚酯线。铁丝重量和硬度大，使得安装和调节困难。

　　塑钢线聚酯线重量轻和易弯曲的特点，安装简便。铁丝腐蚀断裂后很难被修复。而塑钢线聚酯线不断裂，拉力强。以上塑钢线聚酯线跟铁丝钢丝的明显对比，塑钢线聚酯线价格低，质量优，环保，使用方便，塑钢线聚酯线的完美可以代替铁丝钢丝的使用。

The iron wire will expand and contract with the change of temperature, and the thermal expansion and cold contraction are obvious, so the durability is poor. In this case, it is necessary to increase the length of the iron wire, or tighten the iron wire. At the same time, the iron wire is easy to conduct electricity, and in the case of lightning, it may burn the plastic film, or cause certain harm to people. Plastic steel wire will not change with the change of temperature, and will always maintain the original performance and original state, because it is a carbon containing polyester compound, so it is not conductive. In the large greenhouse production base, the loose iron wire is dangerous to the machine and will scrap the expensive machine. The existing machines can be applied to the tight straightening of plastic steel wires, which will not damage the machine.

Iron wire will be easily corroded after a long time of use, while plastic steel wire and polyester wire will not be corroded. Iron wire rust is an insurmountable problem. Rusted iron wire will affect the service life of plastic film and shorten the service life of iron wire. Plastic steel wire and polyester wire will not rust, with a service life of up to ten years. Iron wire and steel wire should invest manpower and material resources to tighten the iron wire once a year. Plastic steel wire polyester wire does not need human and material input to tighten plastic steel wire polyester wire. The heavy weight and hardness of the iron wire make installation and adjustment difficult.

Plastic steel wire and polyester wire have the characteristics of light weight and easy bending, and are easy to install. The iron wire is difficult to repair after corrosion and fracture. The plastic steel wire and polyester wire are not broken and have strong tensile force. The above plastic steel wire polyester wire is obviously compared with iron wire and steel wire. Plastic steel wire polyester wire has the advantages of low price, excellent quality, environmental protection and convenient use. The perfection of plastic steel wire polyester wire can replace the use of iron wire and steel wire.
