山东鸿宝化工生产的高分子聚乙烯塑料枕木为何如此畅销，已慢慢代替传统的木质枕木呢？
Why is the polyethylene plastic sleeper produced by Ningjin County Hongbao Chem Co., Ltd. so popular that it has gradually replaced traditional wooden sleepers
小编带你一起看一下我公司生产的塑料枕木 铁路轨枕和木质枕木相比有哪些优点：
Let's look at the plastic sleepers produced by our company. The advantages of railway sleepers and wooden sleepers:
传统的木头枕木寿命比较短，有开裂、腐烂、虫蛀等问题，于是采用一些比较特殊的木材，如柞木等，并进行防虫、防水、耐火等处理。虽然这样，随着现代铁路的扩展，这些木材来源紧张，而且，随着速度和载重的提高，木枕无法满足需要。
The traditional wood sleepers have a short life span, such as cracking, rot, and insect infestation. Therefore, some relatively special woods, such as beech wood, are used, and pest control, waterproofing, and fire-resisting treatments are performed. In spite of this, with the expansion of modern railways, these timber sources are strained, and, with the increase in speed and load, wooden pillows cannot meet their needs.
枕木又称轨枕，只不过现在所用材料不仅仅是木材，因此叫轨枕更加科学。别看轨枕的模样单调划一，貌不惊人，它的作用可不小。轨枕既要支承钢轨，又要保持钢轨的位置，还要把钢轨传递来的巨大压力再传递给道床。它必须具备一定的柔韧性和弹性，硬了不行，软了也不行。
Sleepers, also known as sleepers, are now more than just wood, so they are more scientific. Do not look at the monotonous appearance of the sleeper, the appearance is not surprising, its role is not small. The sleeper must support both the rails and the position of the rails, and transfer the great pressure from the rails to the track bed. It must have a certain degree of flexibility and flexibility. If it is hard, it will not work.
