机械行业中,粘接技术对提高产品质量、简化装配工艺、节省能源等具有较大作用,有较高的经济效益,值得大力推广应用。厌氧胶是最常用的粘接剂,具有很多优点:(1)与空气接触时呈液态,与空气隔绝在常温下可自行聚合固化形成牢固的粘接膜;(2)单组分,不需配比混合,使用方便,安全可靠,不含溶剂,基本无毒;(3)渗透性能较好,固化收缩少,有良好的抗振性和密封性;(4)胶层有良好的耐油、耐水、耐酸、碱性,对金属还有防锈作用;(5)粘接强度介于结构胶与非结构胶之间,允许组合件拆卸再用;(6)涂胶不需特殊工具,胶液存放时间可达一年以上。因此厌氧胶在上海冶金
Mechanical industry, bonding technology to improve product quality, simplify assembly process, save energy has a greater role, have higher economic benefits, it is worth to promote the application. Anaerobic adhesive is the most commonly used adhesive, has many advantages: (1) liquid contact with air, isolated from the air at room temperature can be self-curing to form a solid adhesive film; (2) single-component, not Need to mix, easy to use, safe, reliable, solvent-free, basically non-toxic; (3) better permeability, curing shrinkage less, good vibration resistance and sealing; (4) (5) the bonding strength between the structural adhesive and unstructured glue, allowing the assembly to disassemble and reuse; (6) glue without special tools, Glue storage time of up to one year.
