鳞片胶泥衬里中玻璃鳞片在树脂中的非连续分布
水性环氧玻璃鳞片防腐胶泥,是指将具有一定片径和厚度的玻璃鳞片分别与各种耐腐蚀树脂、辅料等混合,经专用机械配制而成的胶泥。由于玻璃鳞片的多层平行排列,大大延长了渗透路径,具有优异的抗渗性能。鳞片胶泥衬里中玻璃鳞片在树脂中的非连续分布,使鳞片胶泥衬里具有理想的抗应力破坏失效能力,从而更适合大型和有温度变化设备的内衬防腐。根据腐蚀等级、重要性和检查维修困难程度,采用水性环氧玻璃鳞片防腐胶泥防护,胶泥的厚度1~2mm。
The waterborne epoxy glass scale anti-corrosion adhesive is a kind of adhesive prepared by mixing the glass scale with a certain diameter and thickness with various corrosion-resistant resins and auxiliary materials and special machinery. Because of the parallel arrangement of glass flakes, the penetration path is greatly extended, and the glass flakes have excellent impermeability. The discontinuous distribution of glass flakes in the resin makes the flake cement lining have ideal stress failure resistance, which is more suitable for anticorrosion of large-scale and temperature changing equipment. According to the corrosion grade, importance and the difficulty degree of inspection and maintenance, the water-based epoxy glass scale anti-corrosion cement is used for protection, and the thickness of the cement is 1-2mm.
水性环氧玻璃鳞片防腐胶泥的存在就是将涂层分离成无数的小区域,这种小区域有效地阻止了涂层内微裂纹的产生,从而减少了由于毛细作用而引起的渗透.玻璃鳞片的平行排列与被分离成的小区域使涂层在交联过程中或溶剂挥发时产生的小气孔与漆膜针孔被相互隔离,而且鳞片排列方向与介质渗透方向垂直也抑制了介质的渗透。
The existence of waterborne epoxy glass scale anti-corrosion adhesive is to separate the coating into numerous small areas, which effectively prevent the generation of microcracks in the coating, thus reducing the permeability caused by capillary action. The parallel arrangement of glass scales and the small areas separated make the small pores produced in the process of cross-linking or solvent evaporation and the pinholes of the paint film mutually In addition, the scale arrangement direction is perpendicular to the medium penetration direction, which also restrains the medium penetration.
