| 混凝土界面剂是一种聚合物改性水泥砂浆，能够增强对基层的粘结力，具有良好的耐水、而湿热、抗冻融性能、避免了抹灰层空鼓、起壳的现象，从而代替人工凿毛处理，省时省力。主要用于混凝土基层抹灰的界面处理和大型砌块的表面处理。 Concrete interface agent is a kind of polymer modified cement mortar, can enhance the cohesive force of the grass-roots level, has good water resistance, damp heat, frost resistance, avoid hollowing coat, the shell of the phenomenon, instead of artificial chiseling, saving time and effort. It is mainly used for the interface treatment of concrete base plaster and the surface treatment of large block. 混凝土用结构界面剂宜采用改性环氧类界面剂。 The interface agent for concrete structure should be modified epoxy interface agent. 结构界面剂剪切粘结性能指标应符合下表的规定。 The index of shear bond properties of structural interface agents should be in accordance with the provisions of the table below. 性能指标 performance index 界面剂等级 Interfacial agent grade 28d合格指标 28d qualification index 剪切粘结强度（MPa） Shear bond strength (MPa) A级 A ≥3.5 More than 3.5 且为混凝土内聚破坏 And damage to the cohesion of concrete B级 B ≥2.5 More than 2.5 GJ-302混凝土界面剂施工工艺 Construction technology of GJ-302 concrete interface agent 一、新老混凝土连接施工： First, new and old concrete connection construction: 1、砂浆配置：按照-302混合胶液：水：水泥：黄砂=1 : 1 : 3 : 4的比例进行混合搅拌。 1, according to the -302 configuration: mortar mixed glue: water: cement: sand =1: 1: 3: 4 ratio of mixing. 2、基层拉毛：用刷子或扫帚等工具将搅拌好的混合胶液砂浆甩刷在基层上，拉成粗糙面，硬化后即可进行抹灰施工。 2, grassroots napping: with brush or broom tools such as mixing the glue mortar good throwing brush at the grass-roots level, pull into the rough surface, hardening can be carried out after plastering construction. 3、参考用量：约0.3kg/m2。 3, reference amount: about 0.3kg/m2. 二、混凝土起砂基层处理： Two, concrete sand base treatment: 1、砂浆配置：按照-302混合胶液：水泥：黄砂=1 : 1-2 : 1-2 的比例进行混合搅拌。 1, according to the -302 configuration: mortar mixed glue: cement: Sand: =1 1-2: 1-2 ratio of mixing. 2、清除已经脱落或疏松的灰砂，将混合胶液用水稀释1-2倍后，涂刷在起砂基层上，使胶液较大限度地渗透进入基层。 2, have clear off or loose sand, mixed glue diluted 1-2 times after brushing in sand base, make the glue effectively penetrated into the base. 3、将配置好的混合砂浆在起砂部位刮涂1-2遍后，洒水泥压光，按照正常的抹灰施工进行养护。 3. After the mixed mortar is scraped for 1-2 times in the sanding position, the cement is sprinkled with cement, and the maintenance is carried out according to the normal plastering construction. 5、参考用量：每道工序用量约0.2kg/m2，修复层厚度不同用量会有变化。 5, reference dosage: the dosage of each process is about 0.2kg/m2, and the different thickness of the thickness of the repair layer will change. 三、混凝土表面保护与防潮处理： Three, concrete surface protection and moisture-proof treatment: 1、砂浆配置：按照-302混合胶液：水泥：细砂=1 : 1-2 : 1-2的比例进行混合搅拌。 1, mortar configuration: in accordance with the -302 mixture: cement: fine sand =1: 1-2: 1-2 of the proportion of mixing. 2、将配置的混合砂浆均匀地涂刷在基层上，靠前道用较稀一点的混合砂浆，第二、三道要用稠一点的混合砂浆。每道工序间隔须在4小时以上。 2, the mixed mortar will be evenly painted on the base, with a thinner mixed mortar on the front road, and the second, third to use a thicker mixed mortar. The interval between each process must be more than 4 hours. 3、一般地混凝土保护须涂刷二道，防水防潮处理须涂刷二至三道,用量：每道工序用量约0.2kg/m2，厚度不同用量会有变化。 3, in general, the concrete protection must be brushed two. The waterproofing and moisture-proof treatment must be brushed two to three times. The dosage is about 0.2kg/m2 for each process and the thickness will vary with different thickness. 四、有耐酸碱腐蚀要求场合的抹灰或砖板粘贴施工： Four. Plastering or brick plastering construction with acid and alkali corrosion requirements: 1、砂浆配置：按照302混合胶液：水：水泥：黄砂=1 : 1 : 2-4 : 4-6 的比例进行混合搅拌,使用配置好的混合砂浆按照正常抹灰或者铺贴陶瓷砖的施工方法和要求进行施工即可。参考用量：以3-4mm结合层厚度计算，混合胶液用量约0.5kg/m2 1, mortar configuration: according to the 302 mixed glue: water: cement: Sand: 1 =1: 2-4: 4-6 ratio of mixed use, mixed mortar construction can be configured according to the construction method of normal plastering or Putie tile and requirements. Reference amount: with the thickness of 3-4mm binding layer, the dosage of mixed liquid is about 0.5kg/m2 包装存运包装规格为：甲组份为：15kg±0.5kg 乙组份为：45kg±0.5kg,存放在5℃以上阴凉干燥通风处，避免曝晒、雨淋冰冻，保质期6个月，无毒、无味、不燃、不爆，按一般货物运输。 Packaging storage and transportation packaging specifications: A: 15kg + 0.5kg B: 45kg + 0.5kg, stored in a cool and dry place at 5 DEG C, avoid exposure, freezing rain, the shelf life of 6 months, non-toxic, tasteless, no burning, no explosion, according to the general cargo transport. |
