双组份聚氨酯密封胶 嵌缝密封胶 黑白双组份密封胶

　　Two component polyurethane sealant and two-component sealant sealant

　　双组份聚硫密封胶施工方法: 1.被密封表面的处理: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。

　　A two-component polysulfide sealant construction method: 1. sealed surface treatment: to remove oil, sticky surface attachment before construction, dust and other debris, ensure the adherend surface dry, smooth, to prevent bad adhesion.

　　2.填充背衬材料:按设计要求，向接缝内填充背衬材料,然后再施用双组份聚硫密封胶。 双组份聚硫密封胶

　　2. filling backing material: according to the design requirements, filling the back lining material into the joint, and then applying the two component polysulfide sealant. Two component polysulfide sealant

　　3.涂刷底涂液: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。

　　3. brushing the bottom coating solution: the design requires the use of the bottom coating liquid engineering, or long-term immersion parts of the seal, need to besmear the bottom coating solution brushing on the sticky surface, drying film.

　　4.密封剂的配制: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。

　　4. sealant preparation: according to the specifications given by the mix, the two components can be mixed evenly, can be used, regardless of mixing or manual mixing, should achieve uniform color, no color difference.

　　混合时应防止气泡混入，涂双组份聚硫密封胶时应防止气泡混入，压实，填平密封处。

　　Mixing should prevent bubbles from mixing, and when coating two-component polysulfide sealant, the bubbles should be prevented from mixing, compacting and sealing.
