植筋胶技术简介 (Bar Glue Technical Profile)​​

​​特点 (Features)​​

植筋胶为双组分环氧树脂基高粘结材料，具有​​超高粘结强度​​（钢-钢剪切强度≥35 MPa）、​​宽温域适应性​​（-50℃~250℃短期耐受）及​​低收缩率​​（固化收缩≤2%），可深入混凝土微孔形成​​韧性锚固层​​（elastic modulus ≥12000 MPa）。其​​耐酸碱/水/油介质​​（acid/alkali/water/oil resistance）和​​抗老化性​​（湿热老化90天强度损失≤10%）显著优于传统锚固剂，且​​常温固化​​（25℃初凝3-7天）支持断续施工。

​​优点 (Advantages)​​

• ​​长效可靠​​：承载力达钢筋屈服强度的90%以上，使用寿命超20年；
• ​​施工高效​​：无需预埋，钻孔后直接注胶植筋，工效提升40%；
• ​​环保安全​​：100%固含量，无VOC排放（符合GB50728-2011）；
• ​​多功能性​​：支持焊接后锚固（耐400℃短暂高温），适配碳纤维协同加固
   
  。

​​用途 (Applications)​​

• ​​建筑加固​​：梁柱钢筋补强、结构扩跨植筋（抗拉强度≥210 kN）；
• ​​桥梁工程​​：桥墩锚固、预制板连接（承载力提升30%-50%）；
• ​​工业设备​​：重型机械基座固定、管道支架焊接锚固；
• ​​轨道交通​​：隧道管片连接、轨道板防震加固（抗疲劳性提升5倍）。

​​Bar Glue Technical Profile​​

​​Features​​

Bar glue is a dual-component epoxy-based high-performance anchoring material, featuring ​​ultra-high bond strength​​ (shear strength ≥35 MPa, steel-steel), ​​wide temperature adaptability​​ (-50℃~250℃ short-term), and ​​low shrinkage​​ (≤2% curing). It penetrates concrete pores to form a ​​tough anchoring layer​​ (elastic modulus ≥12000 MPa), with ​​acid/alkali/water/oil resistance​​ and ​​anti-aging properties​​ (≤10% strength loss after 90-day thermal-moisture aging). Ambient curing (3-7 days at 25℃) allows intermittent operations。

​​Advantages​​

• ​​Long-term reliability​​: Load-bearing capacity reaches 90% of rebar yield strength, service life >20 years;
• ​​High efficiency​​: Eliminates pre-embedding, direct post-drilling grouting improves productivity by 40%;
• ​​Eco-safety​​: 100% solid content, zero VOC (GB50728-2011 compliant);
• ​​Multi-functionality​​: Weldable post-anchoring (withstands 400℃ transient heat), compatible with CFRP reinforcement
   

  .

​​Applications​​

• ​​Civil engineering​​: Beam/column rebar strengthening, structural widening (tensile strength ≥210 kN);
• ​​Bridge engineering​​: Pier anchoring, precast slab connections (30%-50% load capacity enhancement);
• ​​Industrial equipment​​: Heavy machinery base fixation, pipeline bracket welding;
• ​​Rail transit​​: Tunnel segment joints, track slab seismic reinforcement (5× fatigue resistance improvement)
