遇水膨脹止水膠是一種遇水膨脹、單液、彈性密封膠。它以聚氨酯的預(yù)體為基礎(chǔ)、含有特殊接枝的尿烷。具有橡膠的彈性止水和遇水后自身的體積膨脹止水的雙重密封止水機(jī)理，適用于混凝土施工縫防水和各類(lèi)預(yù)埋構(gòu)件的防滲漏。遇水膨脹止水膠可以在潮濕環(huán)境中固化。固化時(shí)間取決于環(huán)境溫度和濕度。溫度越高或濕度越大，固化時(shí)間越短。表面硬化（指觸干燥）后即可進(jìn)行下一次混凝土澆筑。
Water swelling sealant is a kind of water swelling, single liquid and elastic sealant. It is based on urethane prepolymer and contains specially grafted urethane. The double sealing and water stopping mechanism with rubber elastic water stop and water volume expansion and water sealing after encountering water is applicable to waterproof of concrete construction joints and leakage prevention of various bded components. Water swelling sealing glue can be solidified in humid environment. The curing time depends on the ambient temperature and humidity. The higher the temperature or the higher the humidity, the shorter the curing time. Surface hardening (refers to drying) can be the next concrete pouring.
主要特點(diǎn)：
Main features:
止水效果好具有橡膠的彈性止水和遇水后自身的體積膨脹止水的雙重密封止水機(jī)理，最大能抗1.2Mpa的水壓；
The sealing effect is good, and it has the double sealing and sealing mechanism of rubber elastic water stop and the volume expansion and water sealing after water encountering, which can resist the water pressure of 1.2Mpa maximum;
耐久性強(qiáng)、質(zhì)量變化率低止水膠結(jié)構(gòu)中含尿烷聯(lián)結(jié)鏈，在長(zhǎng)期時(shí)間內(nèi)不會(huì)造成膨脹元流失，在常溫下，使用壽命超過(guò)100年；
It has good durability and low quality change rate, and contains urethane coupling chain in water sealing structure. It will not cause expansion element loss in long time, and its service life is more than 100 years at normal temperature;
緩膨脹性好 其7天的膨脹率占最張的膨脹率≤50%（實(shí)測(cè)值可達(dá)39.3%），非常適用于潮濕多水的施工環(huán)境；
The 7 day of slow expansion expansion rate accounted for less than 50% of the expansion rate of a (measured value of up to 39.3%), very suitable for the construction of watery environment;
施工便捷單組分、膠狀物，可使用標(biāo)準(zhǔn)嵌縫膠施工槍?zhuān)皇┕っ苜N 能牢固地粘貼在混凝土表面，而不論基面是否潮濕、光滑或粗糙。
The construction is convenient, single component jelly, you can use standard caulk gun construction; construction of dense paste can be firmly pasted on the surface of the concrete surface, regardless of whether moist, smooth or rough.
環(huán)保具有良好的耐化學(xué)品性能，可以耐鹽酸、鹽水、碳酸鈉、氫氧化鉀等化學(xué)物品；可與飲水接觸、安全、無(wú)毒，屬環(huán)保型產(chǎn)品。
Environmental protection has good chemical resistance, can resist hydrochloric acid, salt water, sodium carbonate, potassium hydroxide and other chemicals; can contact with drinking water, safe, non-toxic, environmental protection products.
