下面我們詳細(xì)介紹一下雙組份聚硫密封膠產(chǎn)品特點：
Below we detail the characteristics of two-component polysulfide sealant products:
1、首先環(huán)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(chǎn)的聚硫密封膠經(jīng)中國預(yù)防醫(yī)學(xué)科學(xué)院環(huán)境與衛(wèi)生工程研究所測試其L,D50 >20g／kg。根據(jù)國家毒性分級標(biāo)準(zhǔn)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(jié)性：作為密封膠最重要的是必須具有極好的粘結(jié)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(xiàn)密封膠流淌從施工縫中掉下來的現(xiàn)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(jié)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(jié)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%.
4、耐水性：聚硫密封膠對海水、自來水、蒸餾水的作用是穩(wěn)定的，相比之下對海水(含鹽)的重量變化最小。
4, water resistance: polysulfide sealant on the sea water, tap water, distilled water is stable, compared to the sea water (salt) of the weight change is minimal.
5、耐酸、堿性能：聚硫密封膠不耐濃酸、堿。但對稀的無機酸、堿及各種鹽類還是穩(wěn)定的。
5, acid and alkali performance: polysulfide sealant is not strong enough acid and alkali. But it is stable for dilute inorganic acids, alkalis and various salts.
6、耐熱老化性能：聚硫密封膠熱老化性能很好，可長期在一40℃～120℃的條件下工作。
6, heat aging performance: polysulfide sealant thermal aging performance is very good, can long-term in a 40 ~ 120 degrees Celsius conditions work.
7、耐輻射性能良好：聚硫密封膠耐r_射線的性能非常好。
7, good radiation resistance: polysulfide sealant r_ ray performance is very good.
