玻璃钢标志桩的详细介绍 The detailed introduction of the glass steel mark pile 　　玻璃钢标志桩是FRP拉挤型材，其采用玻璃纤维及其制品作为增强材料，以合成树脂作基体材料通过玻璃钢拉挤机一次性拉挤成型。经高温压制而成。抗冲击，耐磨损，耐高温，耐腐蚀，可以抗水、汽油、酒精、电解盐、醋酸、盐酸、钠钾化合物、尿、沥青，适合各种酸碱土壤。使用寿命长达30年。采用丝网印刷技术，警示效果好，不需要维护。重量轻，便于运输安装。无回收价值，自然防盗。 Glass fiber reinforced plastic signs pile is FRP pultrusion profiles, and its using glass fiber and its products as reinforced material, synthetic resin as matrix materials by FRP pultrusion machine one-time pultrusion. It is compressed by high temperature. Impact resistant, wear resistance, high temperature resistance, corrosion resistance, can resist water, gasoline, alcohol, DianXieYan, acetic acid, hydrochloric acid, potassium sodium compounds, urine, asphalt, suitable for all kinds of acid and alkali of soil. It has a life span of 30 years. Using screen printing technology, the warning effect is good, no maintenance. Light weight and easy to transport installation. No recycling value, natural security. 　　1、比重轻、抗腐蚀、耐老化、密封性能好，安全美观，具有全天候防护功能，能够满足室外工程项目中各种恶劣环境和场所的需要. 1, the proportion of light, corrosion resistance, ageing resistance, good seal performance, safe and beautiful, have all-weather protective function, can satisfy the outdoor projects in need of various kinds of bad environment and place. 　　①、拉伸强度≥160MPa The tensile strength is greater than 160MPa 　　②、弯曲强度≥190MPa The bending strength is greater than 190MPa 　　③、浸水后弯曲强度≥150MPa The bending strength is greater than 150MPa when submerged 　　④、巴氏硬度≥38Barcol The hardness is greater than that of 38Barcol 　　⑤、环钢度（5%）≥50KPa4、巴氏硬度≥8Barcol The degree of ring steel (5%) is greater than 50KPa4 and the hardness is greater than 8Barcol 　　⑥、热变形温度≥160℃ 6, heat deformation temperature of 160 ℃ or higher 　　⑦、氧指数26% The oxygen index is 26%
