玻璃钢复合材料竖井梯子间1988年研制成功。初期于兖州、滕南、徐州、淮北等矿区十多个井筒安装使用,效果良好。本产品的推广应用为井筒装备防腐开辟了一条新路。它是井筒装备材料的重大改革,在国内尚属首创。 该产品的问世,解决了长期以来梯子间装备防腐这项一直没有得到很好解决的重要难题。玻璃钢复合材料梯子间具有重量轻、强度大、阻燃、抗静电等优越性能。尤其应用于井筒淋水大、湿度高、酸碱浸蚀严重的恶劣环境中,安全可靠,效果更为显著。更重要的是使用寿命可由原金属装备的10年左右延长到35～40年,工期亦可缩短近三分之一。
FRP composite shaft ladder between the successful development in 1988. Initially in Yanzhou, Tengnan, Xuzhou, Huaibei and other mining areas more than 10 wellbore installation, the effect is good. The popularization and application of this product has opened up a new road for wellbore equipment corrosion protection. It is a major reform of wellbore equipment materials, is still the first in China. The advent of this product has solved the longstanding problem of anti-corrosion equipment between ladders that has not been well solved. Fiberglass composite ladder with a light weight, high strength, flame retardant, anti-static and other superior performance. Especially for large borehole water, high humidity, acid-base corrosion severe harsh environment, safe and reliable, the effect is more pronounced. More importantly, the service life can be extended from the original metal equipment of about 10 years to 35 to 40 years and the construction period can be shortened by nearly a third.
