2007-09-10 Company / Department / Name / File name 瓷砖外墙的主要缺陷 Main Defects of Tile Facade 失去原有的风采 Loss of Image; 污染严重、色彩不均匀及接缝积灰 Staining, Color difference and Dirty Joints; 表面龟裂 Crazing and Surface Cracking; 水的渗透及返潮 Water Penetration and Dampness; 水泥中钙的溶出 Efflorescence; 粘接破坏、瓷砖大面积空鼓和坠落 Adhesion Failure, Tile Surface Buckling and Tile Falling; and 施工质量差及表面不平整等 Poor Workmanship and Unevenness 造成缺陷的原因 Cause of Defects 过度的潮湿膨涨 Excessive moisture expansion 釉面的龟裂 Crazing of glazed surface 不同的温差 Differential thermal movement 徐变及干缩 Creep or shrinkage 北方地区的冻涨 Frost expansion in north China 金属埋件的腐蚀膨胀引起的剥落 Spalling due to corroding of metal elements 不合格的粘接剂及施工质量差 Low grade Adhesive or poor workmanship 旧 瓷 砖 外 墙 的 翻 新 方 法Solution for the Old Tile Facade 铲除旧瓷砖-费工时,高成本 Removal and replacement of old Tile - High Cost-long breakdown time; 安装`铝塑板 Cladding over old tile facade - for High-Grade Image (Commercial) Building; 瓷砖翻新腻子和涂料 Skim coat and Painting over old tile facade. 瓷砖翻新界面剂和涂料 Bonding agent and Painting over old tile facade 聚合物乳液改性瓷砖翻新腻子优点 Improve the adhesive strength to tiles 提高与磁砖面的粘结强度, Absorb deformation from substrate and enhance the cracking resistance of skim coat 缓冲基材的形变,提高腻子的抗裂性 Protect building from ingress of moisture 防潮 Provide a decorative and durable finish 提供一个耐久的装饰涂层 聚合物乳液改性瓷砖翻新腻子优点 By improving adhesion, cohesion and reducing permeability, polymer emulsion can significantly improve the quality of the skim coat. 由于提高了附差力,内聚力,抗渗性能,聚合物乳液大幅度地改善了腻子的质量, Skim Coats modified with polymer emulsion will insure that the surface to be painted is smooth and consistent in absorbency. This will improve the appearance of the painted wall. 聚合物乳液改性腻子确保油漆表面外观色彩均衡光泽均匀. 界面剂粉料推荐起始配方 粉 料 (%, 重 量 ) 42.5MPa普 硅 水 泥 (或 白 水 泥 ): 45 325 目碳 酸 钙 : 0 ~ 16.5 70∽ 140 目 石英粉: 55 ~ 38.5 甲 基 纤 维 素 (10000 ~ 60000cps): 0.2 ~ 0.4 总 量 : 100 界面剂液料推荐起始配方 液
