分类
classification
一般为可硫化型。按组分可分为双组分(或三组分)和单组分型。其加工采用预混-研磨-灌装的工艺方法。聚硫密封胶广泛用于土木建筑、汽车制造等行业作为嵌缝、密封材料,还常用于各类油箱、燃料罐、航空机械、复合玻璃的密封。
Generally curable type. Components can be divided into two components (or three components) and a single component type. The process of mixing, grinding and filling is adopted. 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.

application
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
Specific properties and applications 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.
Below we detail the characteristics of two-component polysulfide sealant products:
1、首先环保无毒性: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. First of all, environmental protection non-toxic: Although liquid polysulfide sealant a little sulfur smell odor, but gradually solidified by the adsorption of filler. The polysulfide sealant produced by our company was tested by the Institute of environmental and sanitary engineering of Chinese Academy of preventive medicine, L, D50, >20g / kg. According to the national toxicity classification standard, it belongs to non-toxic grade. Therefore, the two-component polysulfide sealant can be used for water storage, swimming pools, water works 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 air tightness: two component polysulfide sealant not only has good elasticity, but also its tightness in 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 applied to 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 from the construction seam can not occur. Polysulfide sealant has a good bond to cement, steel, glass, wood, natural stone, etc.. 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%.
