很多人对于防腐工艺不是很了解，那么标志桩厂家的防腐是怎样的呢，分为哪几类，有啥区别呢。
Many people don't know much about the anti-corrosion technology, so what is the anti-corrosion of marker pile manufacturers? What are the types and differences?
标志桩厂家的防腐分为内减阻性和内防腐型两种类型，区别在于：内减阻涂层主要目的是用于提高输送介质的频率，防腐层不需要补口；内防腐层主要作用是提高标志桩的使用寿命，内防腐层需要补口。
The anti-corrosion of the mark pile manufacturer can be divided into two types: internal resistance reduction and internal anti-corrosion. The difference is that the main purpose of the internal resistance reduction coating is to improve the frequency of the transmission medium, and the anti-corrosion coating does not need to be patched; the main function of the internal anti-corrosion coating is to improve the service life of the mark pile, and the internal anti-corrosion coating needs to be patched.
总之玻璃钢材质的标志桩具有很好的防腐作用，且重量轻、防偷盗，现广泛适用。
In a word, the sign pile made of glass fiber reinforced plastic has a good anti-corrosion effect, and is light in weight and anti stealing, which is now widely used.
