1、单组份高分子合成树脂乳液。具有良好的耐水、耐湿热和优良的抗冻融性,操作简便,无毒无味。
1, the aggregate-organ of polymer synthetic resin emulsion. Have good hydrilysis and hot and humid and excellent freezing-thawing resisting sexual, convenient operation, avirulent insipidity.
2、用于内外墙的批刮腻子、非结构部分的混凝土界面处理,混凝土基层抹灰、修补等,可在潮湿环境下使用。
2, used in the batch blow be bored with child, facades unstructured part of concrete processing interface, concrete base plastering, repair, etc, can be in damp environment use.
一、特点:
A, features:
混凝土界面处理剂是参考国外技术研制而成的一种含环氧树脂的单组分乳液,适用于内外墙批刮腻子,混凝土基层抹灰的界面处理,砼修补、面砖粘贴等,以增加水泥砂浆对层的粘接力,代替对基层的碱洗除油和凿毛处理,避免抹灰及面砖空鼓、脱落。BT-7025混凝土界面处理剂粘接性能好,操作方便,处理剂涂刷于基层后,可在干湿状态下抹灰,因而施工质量易于保证。已在上海南浦大桥,北京交通指挥中心,核工业情报所等工程广泛使用。
  type concrete interfacial treatment is reference foreign technology developed by a single composition containing epoxy resin emulsion, suitable for external batch blow be bored with child, concrete base plasterer interface processing, concrete repair, brick affix etc, in order to increase cement mortar for layer of mucous relay, instead of grassroots the soda-wash oil removal and cut hair treatment to avoid the plasterer and brick empty drum, fall off. BT-7025 concrete interfacial treatment adhesive performance is good, convenient operation, besmear after treatment in grass-roots, can be in the wet state plastering, thus the construction quality easy assurance. Already in Shanghai Nanpu Bridge, Beijing traffic command center, nuclear industry QingBaoSuo project, etc widely used.
二、性能指标:
Second, performance index:
经BT-7025涂刷处理后的混凝土、面砖与水泥砂浆的粘接剪切强度普遍提高,并具有良好的耐水、耐湿热、抗冻融性能。
The BT-7025 besmear after treatment with brick of the concrete, cement mortar adhesive shear strength are generally improved, and it has good hydrilysis and moist heat, freezing-thawing resisting performance.
