(1) GB底胶固化时间较长，一般为24 h，若在12 h内遇水或浸泡，即使表面填料已施工完成，底胶也会发生化学反应而形成薄片状固状物，致使底胶失去与混凝土面的粘结力。在该工程施工时，因雨天较多，同时由于面板混凝土养护的需要，无法保证涂刷底胶后表面长时间处于干燥状态。底胶失效后，需重新打磨、涂刷。SR底胶的粘结性能较好，不易产生脱胶现象，底胶表面覆盖SR材料后，遇水不会影响粘结效果。
(1) GB adhesive curing time longer, usually 24 h, if water or soaked in 12 h, even if the surface filling has completed the construction, bottom glue chemical reb will occur and the bation of lamellar solids, resulting in the loss and adhesive bonded concrete surface force. In the construction of the project, due to the rainy days, and due to the needs of the maintenance of the concrete slab, it can not guarantee the surface of the rubber after brushing for a long time in a dry state. When the base rubber fails, it needs to be polished and brushed again. The adhesive property of SR base adhesive is good, and it is difficult to produce degumming phenomenon. After covering the SR material on the base surface, the bonding effect will not be affected by water.
大坝周边缝表面止水施工完成后，检查发现GB盖片下部局部有渗水现象，进行了返工处理。
After the completion of the dam surface sealing construction, the inspection found that the lower part of the GB cover piece has the phenomenon of water seepage, and it has been reworked.
(2) GB填料较SR 填料的可塑性及施工性能差。GB填料及盖片在常温下施工时必须对板材加压，但由于现场施工条件的限制，加压不能确保GB与底胶及混凝土表面的紧密粘结，从而影响防渗效果。而SR 材料的可塑性、延展性较好，易施工，能保证SR填料与底胶及混凝土表面粘结紧密。
(2) the plasticity and construction perbance of GB filler are worse than that of SR filler. GB packing and cover plate must be pressed under the normal temperature, but due to the restrictions of field construction conditions, the pressure can not ensure the tight bond between GB and the bottom rubber and concrete surface, thus affecting the anti-seepage effect. The SR material has good plasticity, good ductility, easy construction, and can ensure the SR filler and the bottom glue and concrete surface bonding closely.
鉴于SR填料较易施工，且与混凝土面的粘结较好，该工程SR及GB盖片封边全部采用SR底胶及填料封边。

In view of the easier construction of SR filler and better bonding with the concrete surface, the SR and GB cover sheets of the project all adopt SR bottom adhesive and packing edge banding.
(3) SR底胶涂刷完成后，先进行找平层施工，以改善混凝土与SR 填料的粘结，消除混凝土表面不平整对粘结的影响。而GB填料由于其可塑性较差，无法进行找平层施工，一般是将GB填料和盖片直接覆盖在底胶上加压，这在一定程度上影响了粘结效果。
(3) after the SR primer is finished, the leveling layer is first constructed to improve the bond between concrete and SR filler, and to eliminate the influence of the concrete surface irregularities on the bonding. Because of its poor plasticity, GB filler can not be used for leveling layer construction. Generally, the GB filler and cover sheet are directly covered on the bottom glue to pressurize, which affects the bonding effect to a certain extent.
(4)经检测SR 和GB 盖片的强度、延伸率、热空气老化等性能，均符合设计和规范要求。GB盖片厚13 mm左右， SR盖片厚5～7 cm， GB盖片的质量较大，坡面施工较困难。
(4) the strength, elongation and hot air aging properties of SR and GB cover sheets are all in line with the requirements of design and specification. The thickness of GB cover is about 13 mm, the thickness of SR cover is 5~7 cm, and the quality of GB cover sheet is larger, and the slope construction is difficult.
(5) GB填料采用叠片包装，每片厚3 cm左右，片间粘贴双面防粘纸，施工时防粘纸较容易揭开，同时无需对材料进行大量切割。而SR材料采用大块包装，表面粘贴单面防粘纸，受运输过程的影响， SR材料容易局部变形，造成防粘纸局部扭曲、破损，防粘纸不易揭开，在施工过程中还需进行切割。
(5) GB packing is packed by lamination, each piece is about 3 cm thick, and double anti sticking paper is pasted between the sheets. The anti sticking paper is easy to be uncovered during construction, and it is not necessary to cut a lot of materials. SR bulk materials used in packaging, anti sticking paper stuck to the surface of one side, affected by the transport process, SR material is easy to cause local debation, anti sticking paper local distortion, damage, anti sticking paper is not easy to open, in the construction process also needs to be cut.
二、在施工前应先将底涂液涂于表面，待表面干燥后把缝隙的两边10mm处贴上50mm宽的防护胶带，以防施工中多余的聚硫胶把构筑物表面弄脏。
Two, before the construction, the bottom coating solution should be applied to the surface, after drying the surface, the two sides of the gap 10mm affixed 50mm wide protective tape, in order to prevent the construction of redundant polysulfide glue to the surface of the structure contaminated.
三、 把箱内1桶白色聚硫胶（A组份）与1袋黑色固化剂（B组份）充分搅拌均匀，直到无色差为止。
Three, the box of 1 barrels of white polysulfide glue (A component) and 1 bags of black curing agent (B component) fully stirring, until no color difference so far.
