分類
classification
一般為可硫化型。按組分可分為雙組分(或三組分)和單組分型。其加工采用預混-研磨-灌裝的工藝方法。聚硫密封膠廣泛用于土木建筑、汽車制造等行業作為嵌縫、密封材料，還常用于各類油箱、燃料罐、航空機械、復合玻璃的密封。
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.

應用
application
聚硫密封膠適用于中空玻璃密封、金屬、混凝土幕墻接縫、地下工程（如隧道、洞涵）、水庫、蓄水池等構筑物的防水密封，以及公路路面，飛機跑道等伸縮縫的伸縮密封、建筑物裂縫的修補恢復密封。
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.
雙組份聚硫密封膠特有的性能與用途
Specific properties and applications of two-component polysulfide sealant
雙組份聚硫密封膠主要用于建筑、市政、地鐵、隧道、機場跑道、高速公路、橋梁等工程中的伸縮縫，沉降縫等變形縫的嵌縫密封，雙組份聚硫密封膠適用于水廠、游泳池、蓄水池、電站、攔水壩、污水處理工程及供排水系統等工程中各類伸縮縫防滲漏嵌縫密封。
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.
下面我們詳細介紹一下雙組份聚硫密封膠產品特點：
Below we detail the characteristics of two-component polysulfide sealant products:
1、首先環保無毒性：雖然液體聚硫密封膠有點硫磺的嗅臭味，但固化后逐漸被填料所吸附。我公司生產的聚硫密封膠經中國預防醫學科學院環境與衛生工程研究所測試其L,D50 >20g／kg。根據國家毒性分級標準屬無毒級。因此雙組份聚硫密封膠可以放心用于蓄水池，游泳池、自來水廠等防水工程。
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、氣密性好：雙組份聚硫密封膠不但有良好的彈性，而且它的氣密性在彈性密封膠中也是好的。目前已知各種膠中僅次于熱熔性的丁基膠。可以對工程嵌縫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、粘結性：作為密封膠最重要的是必須具有極好的粘結性，這種聚硫密封膠被涂到建筑物的立縫或者頂縫上以后,
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,
不能出現密封膠流淌從施工縫中掉下來的現象。聚硫密封膠對水泥、鋼鐵、玻璃、木材、天然石材等都有較好的粘結性。一般建筑及水利工程上宜使用低模量、高伸長的聚硫密封膠，其粘結強度≥0．2Mpa，伸長率≥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%.
