产品介绍：TB遇水膨胀止水胶是我公司自主研发的一种单组份遇水膨胀、、湿气固化、弹性密封胶。它以聚氨酯预聚体为基础、含有特殊接枝技术的脲烷膏状体，固化成形后具有遇水体积膨胀和弹性密封止水的双重密封止水机理。
Product introduction: TB water swellable rubber sealing is my company independent research and development of a single component, moisture curing, water swelling, elastic sealant. It is based on polyurethane prepolymer and urethane paste with special grafting technology. After curing, it has double sealing and sealing mechanism of water volume expansion and elastic sealing.

该产品主要适用于工业与民用建筑地下工程、市政隧道、防护工程、山岭及水底隧道、地下铁道、污水处理池等工程的施工缝（含后浇带）、变形缝和预埋构件的防水，以及既有工程的渗漏水治理。
The construction of the products are mainly used in industrial and civil buildings, underground engineering, municipal tunnel protection works, mountains and underwater tunnel, underground railway, sewage treatment pond engineering joints (including pouring belt), buried member joints and pre deformation waterproof, as well as water leakage in engineering management.
产品特性：
Product characteristics:
止水效果好 具有橡胶的弹性止水和遇水后自身体积膨胀密封的双重止水机理，最大抗水压≥1.5Mpa
The elastic sealing rubber has good sealing effect and water volume expansion double seal sealing mechanism, the maximum hydraulic pressure resistance is greater than or equal to 1.5Mpa
耐久性强、质量变化率低：PJ遇水膨胀密封胶中含有特殊接枝技术的脲烷联结链，在长期使用期间不会造成膨胀元流失，在20℃温度下，理论寿命为100年
Strong durability and low mass change rate: PJ water swelling sealant contains urethane coupling chain with special grafting technology. It will not cause expansion element loss during long term use, and the theoretical life is 100 years at 20 temperature.
施工便捷： 单组份、膏状物。可使用标准嵌缝胶施工枪或腻子刀嵌缝施工
The construction is convenient: one, paste. You can use standard caulk gun or putty knife caulking construction construction
粘结性好： 能牢固地粘结在混凝土等基础表面，对基础面含水率要求较低，潮湿亦可牢固粘结
Good adhesion: it can be firmly adhered to the base surface of concrete and so on. The moisture content of the base is low, and the moisture can be firmly bonded.
科技环保： 具有良好的耐化学品性能：可以耐盐酸、海水、碳酸钠、氢氧化钾等化学介质；可直接使用于饮用水工程，安全、无毒，属环保型产品。
Technology and environmental protection: good chemical resistance. It can resist hydrochloric acid, seawater, sodium carbonate, potassium hydroxide and other chemical mediators. It can be directly used in drinking water engineering, safe and non-toxic, and it is an environmentally friendly product.
性价比好： 性能优于传统的施工缝防水材料如钢边橡胶止水带或止水条，价格适中。
Good performance price: performance is better than traditional construction seam waterproof material such as steel edge rubber belt or water stop strip, the price is moderate.
