玻璃钢中含有玻璃成分，根据作用不同，玻璃钢中的含碱量会有明显区别。简单来说，用玻璃碎片作为原料生产的玻璃钢，含碱量就会很高，强度和绝缘性就会随之变弱。而适合用来制作标志桩的玻璃钢，其中含碱量必须近乎于0。也就是说，使用无碱玻璃纤维（或无碱纱）生产的玻璃钢标志桩，才能做到真正的经久耐用。玻璃纤维成分可以分为定送水 保定骨伤骨病 铜鼎铜钟 淤泥固化设备 保定舞蹈 化粪池钢模具 保定网站建设高碱、中碱和无碱，选购玻璃钢标志桩的时候切记选择无碱玻璃钢，这样的产品更加耐久，可靠。金能电力生产的玻璃钢标志桩中，碱金属氧化物含量小于0.8%，化学稳定性，强度和绝缘性能极佳。
Glass fiber reinforced plastics contain glass components. According to different functions, the alkali content of glass fiber reinforced plastics will be significantly different. In short, the glass fiber reinforced plastics produced with glass fragments as raw materials will have high alkali content and weak strength and insulation. However, the alkali content of glass fiber reinforced plastics suitable for making marker posts must be close to 0. In other words, the use of non alkali fiberglass (or non alkali yarn) production of fiberglass marker posts, in order to achieve real durability. Glass fiber composition can be divided into high alkali, medium alkali and non alkali. When choosing glass fiber reinforced plastic marker post, remember to choose non alkali glass fiber reinforced plastic, which is more durable and reliable. Among the FRP marker posts produced by Jinneng Electric Power Co., Ltd., the alkali metal oxide content is less than 0.8%, the chemical stability, strength and insulation performance are excellent
