桥梁用双组份聚硫密封胶施工
双组份聚硫密封胶是国际、国内最领先的防水材料。在国外发达国家中高层建筑均采用聚硫建筑膏的墙体接缝密封。聚硫防水密封膏适用于长期浸水建筑接缝密封 , 与混凝士粘接性能好 , 如 : 地下防水接缝、飞机跑道、贮水污、污水池、地下 工程、大型水利工程均采用聚硫密封膏 , 它具有耐老化性、耐久性、气密 性和防水性 , 良好的粘接性的高伸长橡胶形状高弹性体 , 国内现已在部分 大型水库、贮水池、污水池、地下工程 , 已采用本产品 , 深受工程技术人员的好评。
Two component polysulfide sealant is the most advanced waterproof material in the world and in china. In foreign developed countries, the high-rise building adopts polysulfide building paste wall joint sealing. Polysulfide sealing paste is suitable for long-term immersion building joint sealing, and concrete bonding performance, such as: underground waterproof joint, runway, water pollution, sewage pool, underground engineering, large-scale water conservancy projects adopt polysulfide sealant, it has anti-aging, durability, air tightness and water resistance good adhesion, high elongation rubber shape with high elasticity, has been in the domestic part of large reservoir, storage tank, sewage tank, underground engineering, has been using this product by engineering and technical personnel.

聚合物的性能 :
Properties of polymers:
非下垂型 , 高伸长 , 低模量的聚硫建筑密封膏完全固化后为橡胶状高弹性体。配合比 : 主剂 (A): 固化剂 (B)=100:10( 质量份 , 标准状态下 ), 随季节 , 地域气温的变化。可用固化剂使用量的多少来调节适用期的长短 ,B 组份的变动范围在 8-12 之间
Non sagging, high elongation, low modulus polysulfide sealant is completely cured and then rubber like high elastic body. Mixing ratio: main agent (A): curing agent (B) =100:10 (mass fraction, standard state), seasonal, regional temperature changes. The amount of curing agent can be used to adjust the length of the applicable period, B component of the range of change between 8-12
三、施工方法 ：
Three, construction methods:
1 、被密封表面的处理：
1. Sealing surface treatment:
施工前要除去被粘表面的油污 , 附着物 , 灰尘等杂物 , 保证被粘表面干燥 , 平整 , 以防止粘接不良。

Before construction, remove the greasy dirt, attachment, dust and other impurities on the sticky surface, and ensure that the sticky surface is dry and smooth, so as to prevent the adhesion from being bad.
2 、填充背衬材料：
2, filling back lining material:
按设计要求 , 向接缝内填充背衬材料。
Filling the backing material into the seams according to the design requirements.
3 、涂刷底涂液：
3. Brushing the bottom coating solution:
设计要求使用底涂液的工程 , 或长期浸水部位的密封 , 需要涂底涂液涂刷在被粘表面上 , 干燥成膜。
The design requires the use of the bottom coating liquid engineering, or long-term immersion parts of the seal, need to be coated with liquid coating on the sticky surface, dry film.
4 、密封剂的配制：
4. Preparation of sealant:
按说明书给定的配合比 , 将两个组份混合均匀 , 即可使用 , 不论机混或是手工混合 , 都应达到色泽均匀无色差。 混 合时应防止气泡混入 , 涂胶时应防止气泡混入 , 压实 , 填平密封处。
According to the specifications given by the mixing ratio, the two components can be mixed evenly, can be used, regardless of mixing or manual mixing, should achieve uniform color, no color difference. Mixing should prevent bubbles from mixing, and should prevent bubbles mixing, compaction, filling the sealing area when gluing.
