分类
classification
Generally curable type. The components can be divided into two components (or three components) and one component type. The process of premixing grinding filling is adopted in the process. Polysulfide sealant is widely used in civil construction, automobile manufacturing and other industries as caulking and sealing material, is often used for sealing all kinds of fuel tank, fuel tank, air machine, composite glass.

聚硫密封胶适用于中空玻璃密封、金属、混凝土幕墙接缝、地下工程（如隧道、洞涵）、水库、蓄水池等构筑物的防水密封，以及公路路面，飞机跑道等伸缩缝的伸缩密封、建筑物裂缝的修补恢复密封。
Polysulfide sealant for insulating glass sealing, metal, joints, concrete wall underground engineering (such as tunnel, cave), reservoirs, reservoirs and other structures of waterproof sealing, and road repair, restore the telescopic runway expansion joint sealing, sealing the crack of building complex.
双组份聚硫密封胶特有的性能与用途
Unique properties and uses of two-component polysulfide sealant
双组份聚硫密封胶主要用于建筑、市政、地铁、隧道、机场跑道、高速公路、桥梁等工程中的伸缩缝，沉降缝等变形缝的嵌缝密封，双组份聚硫密封胶适用于水厂、游泳池、蓄水池、电站、拦水坝、污水处理工程及供排水系统等工程中各类伸缩缝防渗漏嵌缝密封。
A two-component polysulfide sealant mainly used in construction, municipal, subway, tunnel, airport runway, highway, bridge expansion project of seam, settlement joints deformation crack sealing seal, two-component polysulfide sealant is suitable for water, swimming pool, reservoir, dam, power plants, sewage treatment works and for drainage system engineering in all kinds of expansion joint leakage sealing seal.
下面我们详细介绍一下双组份聚硫密封胶产品特点：
Here we introduce in detail the characteristics of two-component polysulfide sealant products:
1、首先环保无性：虽然液体聚硫密封胶有点硫磺的嗅臭味，但固化后逐渐被填料所吸附。我公司生产的聚硫密封胶经中国预防医学科学院环境与卫生工程研究所测试其L,D50 >20g／kg。根据国家毒性分级标准属无毒级。因此双组份聚硫密封胶可以放心用于蓄水池，游泳池、自来水厂等防水工程。
1, the first environmental non-toxic: Although liquid polysulfide sealant has a smell of sulfur smell, but gradually solidified by the adsorption of filler. The polysulfide sealant produced by our company was tested by L and D50 >20g / kg by Institute of environmental and sanitary engineering, Chinese Academy of preventive medicine. According to the national toxicity classification standard, it belongs to non-toxic grade. Therefore, two component polysulfide sealant can be used for water storage, swimming pool, water plant and other waterproof projects.
2、气密性好：双组份聚硫密封胶不但有良好的弹性，而且它的气密性在弹性密封胶中也是好的。目前已知各种胶中仅次于热熔性的丁基胶。可以对工程嵌缝施工起到很好的密封性能。
2, good tightness: two component polysulfide sealant not only has good elasticity, but also its tightness in the elastic sealant is also good. At present, after the hot melt butyl rubber adhesive in a variety of known. Can the good sealing performance of the construction project.
3、粘结性：作为密封胶最重要的是必须具有极好的粘结性，这种聚硫密封胶被涂到建筑物的立缝或者顶缝上以后,

3, cohesiveness: as sealant, the most important thing is to have excellent adhesion, this polysulfide sealant is painted on the vertical seam or top seam of the building,

不能出现密封胶流淌从施工缝中掉下来的现象。聚硫密封胶对水泥、钢铁、玻璃、木材、天然石材等都有较好的粘结性。一般建筑及水利工程上宜使用低模量、高伸长的聚硫密封胶，其粘结强度≥0．2Mpa，伸长率≥300％。
The phenomenon of sealant flowing off the construction seam can not occur. Polysulfide sealant has good cohesiveness to cement, steel, glass, wood, natural stone and so on. The general construction and water conservancy project should use the low modulus and high elongation of polysulfide sealant, the bond strength is more than 0.2Mpa, elongation is greater than or equal to 300%.
4、耐水性：聚硫密封胶对海水、自来水、蒸馏水的作用是稳定的，相比之下对海水(含盐)的重量变化最小。
4, water resistance: polysulfide sealant on the sea water, tap water, distilled water is stable, compared to the sea water (salt) weight change minimum.
5, acid and alkali performance: polysulfide sealant is not resistant to concentrated acid and alkali. But it is stable to dilute inorganic acid, alkali and various salts.
6、耐热老化性能：聚硫密封胶热老化性能很好，可长期在一40℃～120℃的条件下工作。
