高模量聚硫密封胶我公司生产可安客户要求加工生产
通用名称：聚硫建筑密封膏（胶），双组份聚硫防水密封胶（膏），PS852双组份聚硫密封胶（膏），PG321双组份聚硫密封胶（膏），SGJL-851双组份聚硫密封膏（胶）
General name: polysulfide building seal paste glue, two component polysulfide waterproof sealant paste, PS852 two component polysulfide sealant paste, PG321 two component polysulfide sealant paste, SGJL-851 two component polysulfide sealing paste glue.
分类：a、按照流动性可分为非下垂型（N）和自流平型（L）两个类型；
Classification: A, according to the liquidity can be divided into non droop type N and self leveling L type two
b、按照位移能力可分为25、20两个级别；
B, according to the displacement capacity, can be divided into 25, 20 and two levels.
c、按照拉伸模量可分为高模量（HM）和低模量（LM）两个次级别：
C, according to the tensile modulus, can be divided into two sub levels: high modulus HM and low modulus LM.
种是非下垂型双组份聚硫密封胶，外观为细腻、均匀膏状物或粘稠体,适用于各种水泥建筑物变形缝，无论建筑物的变形缝是立缝、地缝、还是顶缝、都适用，这种硫密封被涂到建筑物的立缝或者顶缝上以后，不会出现密封胶流淌从施工缝中掉下来的现象，而是直接就粘到上面。
The first one is non droop type two-component polysulfide sealant, the appearance of fine and uniform paste or viscous body, suitable for all kinds of cement building deformation joint, deformation joint of building is both vertical seam and seam or seams, the top are applicable, since the sulfur sealing is applied to the vertical seam or buildings the top slot, does not appear in the fall of the sealant flowing from the phenomenon of construction joints, but directly sticking to them.
第二种是自流平型双组份聚硫密封胶，外观为水状液体胶装物，向水一样，能够在变形缝里流淌,比较稀，它只适用于水泥建筑物变形缝的地缝，具有流淌性，将其按比例配比好以后，直接灌到地缝里，能够流淌到建筑物变形缝里,在施工建筑物平面的地缝时,用自流平型双组份密封胶会省时省力
The second is self leveling two-component polysulfide sealant, the appearance of water like liquid glue, like water to flow, can the deformation joints, relatively thin, it is only suitable for the cement building deformation joint seam, with the flow, according to the proportion after directly poured into seam where can flow to the building distortion seam, construction of buildings in the plane of the seam, with self leveling two-component sealant can save time and effort
产品特点：
Product features:
l、粘结性：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％。
L, cohesiveness: polysulfide sealant has good adhesion 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%.
2、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小。
2. Water resistance: the effect of polysulfide sealant on sea water, tap water and distilled water is stable, and the weight change of seawater salt is the smallest.
3、耐酸、碱性能：聚硫密封胶不耐浓酸、碱。但对稀的无机酸、碱及各种盐类还是稳定的。
3, acid and alkali resistance: polysulfide sealant is not resistant to concentrated acid and alkali. But the rare inorganic acids, bases and various salts are still stable.
4、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。
4. Heat aging properties: polysulfide sealant has good thermal aging performance and can work at 40 - 120 C for a long time.
5、耐辐射性能良好：聚硫密封胶耐r_射线的性能非常好。
5, good radiation resistance: polysulfide sealant resistance to r_ ray performance is very good.
6、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。根据毒性分级标准属无毒级。
6. Nontoxic: Although liquid polysulfide sealant has a smell of smell of sulfur, it is gradually adsorbed by packing after curing. The polysulfide sealant produced by our company has been tested by the Institute of environmental and health engineering of the Chinese Academy of preventive medicine Chinese Academy of Preventive Medicine L, D50 20g / kg. According to the national toxicity classification standard, it is nontoxic grade.
7、气密性好：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的。目前已知各种胶中仅次于热熔性的丁基胶。
7, good air tightness: polysulfide sealant not only has good elasticity, but also its gas tightness is also the best in elastic sealant. At present, after the hot melt butyl rubber adhesive in a variety of known.
