產(chǎn)品特點(diǎn)
本品為無機(jī)混合料，具有快硬、高強(qiáng)、微膨脹、冷操作施工和對(duì)環(huán)境等特點(diǎn)。省去了錨固道釘時(shí)需要熬制加熱工序，避免混凝土軌枕、橋枕因局部受熱可能產(chǎn)生裂縫和降低道釘使用。
一、應(yīng)用范圍
1、適用于鐵路混凝土軌枕、橋枕的道釘錨固，機(jī)械設(shè)備地腳螺栓的錨固。
2、適用于鐵路、隧道、引水隧道、煤礦、橋墩加固、房屋抗震、冶金礦山等地下工程用錨桿進(jìn)行支護(hù)圍巖的快速施工，以及混凝土結(jié)構(gòu)加固工程中牽釘?shù)腻^固，并可滿足鋼筋焊接要求。
二、性能指標(biāo)
