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 cement 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. Anyway, kneading in the hands can stick to the hands, and has good elongation. It can be applied to facade expansion joints, such as pipe interface seal, sewage treatment plant vertical wall expansion joint sealing and waterproofing. The low temperature type of mastic is a cheap type of cement, and it has poor heat resistance. In summer, when the temperature is very high, it will become very soft and no support. It will become very hard in winter when the temperature is low. But the cohesiveness is good and the elongation is general. It is usually used in the sealing and waterproof of the flat expansion joint, such as the expansion joint of the highway, the expansion joint of the workshop and so on.

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 material, waterproof joint thermal construction at the temperature of 130-140 DEG C and the plasticizing. PVC mud has good weatherability, cohesiveness, elastic-plastic, acid and alkali corrosion resistance, reliable waterproof, convenient construction.
3.聚氯乙烯胶泥施工方法：
3. construction method of PVC mud:
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) PVC cement should remove the old cement concrete from the old cement concrete and keep the sundries in the seam and keep dry in the seam. The 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 the seams have been saw.

（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℃，最高温度不超过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 annealed immediately to accelerate the stirring. The filling material can be used at any time and added to the new material. A long period of heating should be avoided in order to prevent the performance of the filling material from changing. 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.
