.双组份聚硫密封膏‘哪里有卖’

聚氯乙烯胶泥按适温性可分为耐温型和低温型，其中耐温型胶泥耐高温可达85度左右，在通常状态下为黑色弹性固体，表面不粘手，用刀切开可见截面非常细腻，用手按压弹性较好，可快速回弹。反正在手中揉，可粘于手上，有较好的伸长率，可应用于立面伸缩缝，如管道接口密封，污水处理厂立墙伸缩缝密封防水。低温型胶泥为低廉型胶泥，耐高温性较差，夏天温度高时变的非常柔软，没有支撑力，冬天气温变低则变的非常坚硬。但粘结性很好，伸长率一般，一般应用于地平伸缩缝的密封防水，如公路伸缩缝，厂房伸缩缝等。

According to the optimum temperature of PVC. The clay can be divided into high temperature and low temperature, the temperature resistant cement high temperature up to 85 degrees Celsius, normally black elastic solid, the surface is not sticky, cut with a knife visible section is very delicate, pressed by hands, good elasticity, quick rebound. It can be applied to the expansion joint of the facade, such as the sealing of the pipe interface, the sealing of the expansion joint of the vertical wall of the sewage treatment plant, and the waterproof. Low temperature mortar is low type clay, poor heat resistance, summer temperature is very soft, no supporting force, winter temperature becomes low, it becomes very hard. But the adhesion is very good, the elongation is general, generally used in the horizon expansion joint sealing waterproof, such as highway expansion joints, plant expansion joints, etc..

2.聚氯乙烯胶泥产品特点：是以煤焦油为基料，按一定比例加入聚氯乙烯树脂、增塑剂、稳定剂、防老剂及填料、在130-140℃温度下塑化而成的热施工防水接缝材料。聚氯乙烯胶泥具有良好的耐候性，粘结性，弹塑性，耐酸碱腐蚀性，防水可靠，施工方便。

2. features: PVC cement with coal tar as the base material, is added according to a certain proportion of PVC resin, plasticizer, stabilizer, antioxidant and filler materials, waterproof joint construction in heat at a temperature of 130-140 DEG C and the plasticizing. Polyvinyl chloride cement has good weather resistance, cohesiveness, elasticity and plasticity, acid and alkali corrosion resistance, waterproof and reliable, and convenient construction.

3.聚氯乙烯胶泥施工方法：

Construction method of 3. polyvinyl chloride cement:

1）聚氯乙烯胶泥对阵旧水泥混凝土要清除已老化的填缝料及缝内杂物，并保持缝内干燥，含水量应小于6%。

1) polyvinyl chloride cement against old cement concrete to remove aging filler and joint debris, and keep the seam drying, water content should be less than 6%.

（2）新水泥混凝土锯完缝后应清理。

(2) the new cement concrete should be cleaned after sawing.

（3）将聚氯乙烯胶泥成品切成2kg左右的小块投入锅内，缓慢升温，不断搅拌，熔化时温度应控制在120℃，*高温度不超过160℃，保持填缝不起泡，不冒黄烟、浓烟。如发现上述现象，应立即退火，加速搅拌，熔好的填缝料可随时取用并加补新料，连续作业。应避免长时间的加热煎熬，以防填缝料性能发生变化。熔化好的填缝料应立即用壶往缝内浇注，填缝料与路面齐平，多余的料尖用铲刀清除，以保持行车舒适。

(3) will be cut into about 2kg PVC finished pieces into the pot, slowly heating, stirring constantly, the temperature should be controlled at 120 DEG C melting, the highest temperature does not exceed 160 degrees, keep filling without foaming, do not take tobacco smoke. If the above phenomenon is found, it should be immediately annealed, accelerated mixing, melting filler can be used at any time and add new materials, continuous operation. Long term heating should be avoided to prevent the change of joint properties. The melted filler should be immediately used to sew in the pot pouring sealant, flush with the road surface, the excess material with the shovel tip clearance, to keep driving comfort.

聚乙烯闭孔泡沫板通用名称：高压闭孔板、闭孔泡沫板、闭孔塑料板、PE泡沫填缝板、塑料填缝板材、接缝板、BW-II型嵌缝板

Generic name: polyethylene foam board, foam board high pressure obturator board, plastic board, PE foam obturator plate, plastic sealing plate, joint plate, BW-II type sealing plate

聚乙烯闭孔泡沫板，是国内一种新型的接缝止水材料，经中国交通部科学院等单位反复测试证明，其性能与木材、软木、橡胶、沥青相比，闭孔泡沫塑料板在国外已广泛应用于公路、道桥胀缝、立交桥、高速公路、机场跑路、地道桥、地下通道、地铁、桥头挡阻墙接缝、公路两侧护坡，路基护坡等混凝土工程中的接缝及止水材料，电厂防潮闸、冷却塔、建筑等工程中混凝土接缝、胀缝及止水材料混凝土公路、高架桥梁、涵洞遂道、机场道、堤坝护坡等水利电力混凝土工程中,也可用作大管径管道的弹性垫层以及渠道的防冻垫层。

Polyethylene foam board, is one of the new joint sealing material, the unit Chinese Ministry of communications Academy of Sciences repeatedly tested, compared its performance with wood, cork, rubber, asphalt, obturator foamcore at abroad has been widely used in highway, bridge expansion joints, overpass, highway, bridge, airport run away the subway, subway, bridge, block wall joint, on both sides of the road slope, joint and sealing material for subgrade slope and concrete engineering in power plant, the floodgate, cooling tower, building engineering concrete joints, expansion joints and sealing material of concrete road, elevated bridge, culvert tunnel, Airport Road, embankment slope protection of water conservancy and electric power in the concrete engineering, antifreezing cushion can also be used for large diameter pipeline elastic cushion and channel.
