水泵线接头防水密封胶

EPDM橡胶弹性密封垫是目前国内外用于拼装式隧道管片密封止水的主流材料。它有单一的多孔型三元乙丙橡胶与遇水膨胀橡胶复合而成。多空型弹性橡胶密封垫能减少装配时的压缩应力，，能延长使用寿命。这种复合的橡胶密封垫具有双重保险的密封止水功能。当工程施工中管片之间产生一定的间隙和偏移时，该产品也能有效的确保密封止水作用。

EPDM rubber elastic sealing pad is the main material used in the sealing and sealing of tunnel segments at home and abroad. It has a single porous three diethylene propylene rubber combined with water expansion rubber. The multi space elastic rubber seal cushion can reduce the compression stress of the assembly and prolong the service life. The compound rubber sealing pad has a double insurance sealing sealing function. When there is a certain gap and migration between the pieces in the construction of the project， the product can also effectively ensure the sealing and sealing effect.

硅酮耐候密封胶硅酮耐候密封胶的主要技术指标中，表征施工性能的有下垂度、挤出性、表干时间，表征固化后耐候胶性能的主要是位移能力和质量损失率。耐候胶的质量损失率与结构胶的热失重相当，主要考察耐候胶在长期使用后的性能变化情况，质量损失率越高，长期使用后性能下降越严重。硅酮耐候密封胶的主要作用是对板块间接缝的密封，由于板块经常会受到温度变化、主体结构变形等影响而发生位移，导致接缝宽度也就会随之发生变化。这就要求耐候胶具有良好的承受接缝位移的能力，在长期承受接缝宽度变化的情况下不发生开裂，这一性能称为耐候胶的位移能力，与结构胶的“变位承受能力”不同。

The main technical indicators of silicone weatherproof sealant， silicone weatherproof sealant， are characterized by sag， extrusion and drying time. The main characteristics of the silicone rubber weatherproof sealant are displacement capacity and mass loss rate. The quality loss rate of weather resistant gum is similar to that of structural adhesive. The performance change of weathering gum after long term use is mainly investigated. The higher the mass loss rate is， the more serious the performance degradation is after long term use. The main function of silicone weatherproof sealant is to seal the joints between plates. As the plates are often affected by temperature changes and main body deformation， the joint width will also change. This requires that the weather resistant adhesive has good ability to withstand the joint displacement， and does not crack under the condition that the joint width is changed for a long time. This property is called the displacement ability of weather resistant glue， which is different from the structural adhesives displacement tolerance.
