Two. The scope of application of this construction scheme is applicable to the sealing operation of the expansion joints of buildings and channels.
三、双组份聚硫密封胶性能  双组份聚硫密封胶,外观为水状液体胶状物,能够在变形缝里流淌,比较稀,具有耐油、耐水、耐大气老化、耐紫外线、耐冲击、耐磨擦、耐高低温( -50 ℃ -120 ℃)无毒、无污染;属低模量,高伸长率等特点。双组份聚硫密封胶具有如下特性:
Three, two-component polysulfide sealant properties of two-component polysulfide sealant, the appearance of water like liquid jelly, can flow in the deformation joints, relatively thin, with oil, water resistance, ageing resistance, UV resistance, impact resistance, abrasion resistance, high and low temperature (-50 DEG -120 DEG), no poison no pollution; low modulus and high elongation, etc.. Two component polysulfide sealant has the following characteristics:
1、具有良好的耐候性、耐久性、长期使用不产生龟裂;
1, with good weather resistance, durability, long-term use does not produce cracks;
2、对被密封构件具有充分稳定的粘接性及耐久粘接性,对水中混凝土具有长期粘接性;
2, the sealing member has a fully stable adhesive and durable bonding, and has long-term bonding to water concrete;
3、水蒸汽透过率极低,双组份聚硫密封胶具有非常好的防水功能;
3, the water vapor transmission rate is very low, two component polysulfide sealant has a very good waterproof function;
4、不受菌类的侵蚀,对菌类的抵抗性极佳;
4. It is not affected by fungi, and has excellent resistance to fungi;
5、对密封构件不产生污染,无腐蚀,双组份聚硫密封胶对人体无害。 总之双组份聚硫密封胶适用于金属、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,以及公路路面等伸缩缝的伸缩密封、建筑物裂缝的修补恢复密封。配合比:主剂(A):固化剂 (B)=100:10( 质量份,标准状态下),随季节、地域气温的变化。可用固化剂使用量的多少来调节适用期的长短,B 组份的变动范围在10-14 之间。夏天施工时,双组份聚硫建筑密封胶就凝固的时间就快一些,冬天施工时,凝固的就稍微慢一些。

5, no pollution to the sealing components, no corrosion, two component polysulfide sealant harmless to the human body. In two-component polysulfide sealant is suitable for metal and concrete wall joint, underground engineering (such as tunnel, Dong Han), reservoir, reservoir and other structures of waterproof sealing, and expansion joints of the highway pavement such as sealing, building repair cracks sealing recovery. Mixing ratio: main agent (A): curing agent (B) =100:10 (mass fraction, standard state), with seasonal and regional temperature changes. The amount of curing agent can be used to adjust the length of the applicable period, B component of the range of change between 10-14. In the summer construction, the two component polysulfide building sealant solidified faster, and in winter construction, solidification is slightly slower.
四、双组份聚硫密封胶的施工方法
Four. Construction method of two-component polysulfide sealant
1、被密封表面的处理:将施工后残留的垃圾杂物清理干净,再用吹风器将浮灰处理干净,若基面潮湿应用喷灯烤干后用钢丝刷刷一遍,以清除烘烤后掉下的水泥屑及尘土。要除去被粘表面的油污及灰尘等杂物,用吹风机吹干净杂物,使涂胶面露出牢固的结构层,接缝表面必须保证完全干燥、清洁。表面所有灰尘必须清刷处理干净。必须绝对保证被粘表面干燥,平整,以防止粘接不良。金属表面的锈层及保护漆也需除去。
1, the sealing surface treatment: waste residue after construction debris will be clean, and then dust blower will clean, if the surface wet dry after application of a wire brush again, to remove dust and cement debris falling after baking. To remove the greasy dirt and dust and other debris on the sticky surface, blow out the sundries with the blower, so that the coating surface is exposed to a strong structural layer, and the joint surface must be completely dry and clean. All dust on the surface must be cleaned and cleaned. Must be absolutely guaranteed to be sticky surface drying, leveling, in order to prevent bonding bad. Rust and protective paint on metal surface also need to be removed.
2、施工前把缝隙的两边1cm处垂直贴上5cm宽的胶带,以防施工中多余的聚硫胶把构筑物表面弄脏。(用过的胶带及时清理)
2, before the construction of the gap on both sides of the 1cm vertical tape 5cm wide, in order to prevent the construction of redundant polysulfide glue to the surface of the structure pollution. Cleaning it with tape
3 、密封胶的配制:把1桶白色聚硫胶(A组份)与1袋黑色固化剂(B组份)充分搅拌均匀,直到无色差为止。混合比例 A:B=100:10~100:14(质量比), 将两个组份混合均匀,搅拌时间宜长不宜短,以免因搅拌不均匀造成局部固化不完全而达不到防水密封效果。混合时应防止气泡混入,配制好的双组份聚硫密封胶应在2小时内用完,否则慢慢增稠造成施工困难和降低性能。
3, sealant preparation: the 1 barrels of white polysulfide (A component) and 1 bags of black curing agent (B component) fully stirring until the color is not so far. Mixing ratio A:B=100:10 ~ 100:14 (mass ratio), mixing the two components evenly, stirring time should be long, not short, so as not to cause uneven local solidification incomplete mixing, and can not reach the waterproof sealing effect. Mixing should prevent bubbles mixing, the prepared two-component polysulfide sealant should be used up within 2 hours, otherwise slowly thickening, resulting in construction difficulties and reduce performance.
4 、涂双组份聚硫密封胶时,用灰刀或胶枪将配制好的密封胶在接缝两侧先涂抹一层,然后再将双组份聚硫密封胶嵌入缝道中间。操作时应尽量防止夹带气泡进入密封胶中。涂胶时,应该压实,填平密封处,防止气泡混入。

4. When coated with two-component polysulfide sealant, the sealant is coated with a layer of sealant with a gray knife or glue gun, and then the two component polysulfide sealant is inserted into the middle of the seam. During operation, the entrained air should be prevented from entering the sealant. When gluing, it should be compacted and sealed to prevent bubbles from mixing.
5、施工结束后,把缝隙两边的防护胶带取下即可,24小时内应避免水冲雨淋。
5, after the end of the construction, the crevice on both sides of the protective tape can be removed, 24 hours should avoid water rushing rain.
6、施工质量的检查: 密封胶施工完毕后应对接缝进行全面检查,如有漏刮、不平、下垂等应及时修补整齐。双组份聚硫密封胶表干时间为24小时,因此在双组份聚硫密封胶未充分固化前,要注意保护,防止雨水侵入而降低性能。
6, construction quality inspection: after the construction of sealant, should be comprehensive inspection of joints, such as leakage, uneven, sagging, etc. should be repaired in time. The dry time of two-component polysulfide sealant is 24 hours. Therefore, before the two-component polysulfide sealant is not fully solidified, attention should be paid to the protection, to prevent the invasion of rainwater and reduce the performance.

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, 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最好的。目前已知各种胶中仅次于热熔性的丁基胶。可以对工程嵌
2, good air tightness: two component polysulfide sealant not only has good elasticity, but also its tightness in the elastic sealant is also the best. At present, after the hot melt butyl rubber adhesive in a variety of known. It can be embedded in the project
