Water swellable rubber sealing is a single component of our company independent research and development of water swelling, moisture curing, elastic sealant. It is based on polyurethane prepolymer and urea containing pasty with special grafting technology. After curing, it has double sealing and sealing mechanism with volume expansion and elastic sealing. Water swellable rubber sealing for a single component, solvent free polyurethane sealant, the water can produce expansion, play a very good sealing effect; filling and good adhesion, ensure the product fill cracks and voids, and for Yu Chaoshi, smooth and rough surface; flexible to ensure it is suitable for irregular surface waterproofing; has good chemical resistance; easy to use.
The construction of water swellable rubber sealing is 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 as well as waterproof, seepage water treatment engineering. Water swellable rubber sealing structure and sealing pipe joint for leakage plugging, such as concrete casting in the rough or smooth joint; sealing joints between precast (such as manholes, box type cable trench, ditch, trench etc.); around H steel joints; sealing bolts or pre cast hole gap around the pile wall; orthogonal sealing etc..
Product characteristics:
The elastic sealing rubber has good sealing effect and water volume expansion double seal sealing mechanism, the maximum pressure resistant than 1.5Mpa strong durability, quality and low rate of change: PJ expansion urethane connecting chain containing special sealant grafting technology of the water, in the long-term use will not cause the loss of expansion during the yuan, at 20 C temperature, theory of life for 100 years.
Convenient construction:
Copy, paste. You can use standard caulk gun or construction putty knife caulking construction and good bonding: firmly adheres to the concrete surface, on the basis of surface moisture content is low, wet can be firmly bonded.
700g一支遇水膨胀止水胶
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。遇水膨胀止水胶为一种单组分、无溶剂聚氨酯型密封胶，遇水后能产生膨胀，起到很好的止水效果；有良好的填充性和粘接性，确保产品填入裂缝和空隙中， 因而适用于潮湿、光滑及粗糙的表面；特有的柔性确保它适合不规则的基面接缝防水；具有好的耐化学介质性能；使用方便。
遇水膨胀止水胶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。遇水膨胀止水胶还用于结构接缝密封和管子渗漏堵止，如混凝土浇铸件中粗糙或光滑结构接缝；密封预制件之间的接缝（如入孔、箱型暗沟、电缆沟、
管道沟等）；H
型钢周围的接缝；密封
螺栓或预铸孔周围的空隙等；正交桩墙的密封等。
产品特性：
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，*大抗水压≥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.
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.
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、*，属环保型产品。
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。
施工方法
1、 对施工表面的灰尘进行清理，对是否平整、干湿无特殊要求。
2、 将密封胶放入挤
胶枪中，前端开口，旋上胶嘴，根据接缝要求切割胶嘴的大小和宽度。
3、 用挤胶枪将密封胶挤到施工缝中。
4、 涂敷的密封胶到固化为止，避免与水接触。

Technology environmental protection:
With good chemical resistance: it can resist hydrochloric acid, sea water, sodium carbonate, potassium hydroxide and other chemical media; can be used directly in drinking water projects, safe and non-toxic, environmentally friendly products.
Cost-effective:
The utility model has the advantages of superior performance to the traditional construction joint waterproof materials, such as steel edges, rubber water stopping strips or water stopping strips, and the cost is moderate.
Construction method
1, dust on the construction surface cleaning, whether it is smooth, dry and wet without special requirements.
2, the sealant into the glue gun, the front opening, spin on the mouth, according to the requirements of the joint to cut the size and width of the plastic nozzle.
3. Squeeze the sealant into the construction joint with a glue gun.
4. Apply sealant to curing so as to avoid contact with water.
