聚氯乙烯膠泥按適溫性可分為耐溫型和低溫型，其中耐溫型膠泥耐高溫可達85度左右，在通常狀態(tài)下為黑色彈性固體，表面不粘手，用刀切開可見截面非常細膩，用手按壓彈性較好，可快速回彈。反正在手中揉，可粘于手上，有較好的伸長率，可應(yīng)用于立面伸縮縫，如管道接口密封，污水處理廠立墻伸縮縫密封防水。低溫型膠泥為低廉型膠泥，耐高溫性較差，夏天溫度高時變的非常柔軟，沒有支撐力，冬天氣溫變低則變的非常堅硬。但粘結(jié)性很好，伸長率一般，一般應(yīng)用于地平伸縮縫的密封防水，如公路伸縮縫，廠房伸縮縫等。
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.聚氯乙烯膠泥產(chǎn)品特點：是以煤焦油為基料，按一定比例加入聚氯乙烯樹脂、增塑劑、穩(wěn)定劑、防老劑及填料、在130-140℃溫度下塑化而成的熱施工防水接縫材料。聚氯乙烯膠泥具有良好的耐候性，粘結(jié)性，彈塑性，耐酸堿腐蝕性，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.聚氯乙烯膠泥施工方法：
3. construction b of PVC mud:
1）聚氯乙烯膠泥對陣舊水泥混凝土要清除已老化的填縫料及縫內(nèi)雜物，并保持縫內(nèi)干燥，含水量應(yīng)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）新水泥混凝土鋸?fù)昕p后應(yīng)清理。
(2) the new cement concrete should be cleaned after the seams have been saw.

（3）將聚氯乙烯膠泥成品切成2kg左右的小塊投入鍋內(nèi)，緩慢升溫，不斷攪拌，熔化時溫度應(yīng)控制在120℃，最高溫度不超過160℃，保持填縫不起泡，不冒黃煙、濃煙。如發(fā)現(xiàn)上述現(xiàn)象，應(yīng)立即退火，加速攪拌，熔好的填縫料可隨時取用并加補新料，連續(xù)作業(yè)。應(yīng)避免長時間的加熱煎熬，以防填縫料性能發(fā)生變化。熔化好的填縫料應(yīng)立即用壺往縫內(nèi)澆注，填縫料與路面齊平，多余的料尖用鏟刀清除，以保持行車舒適。
(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 immediaby 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 perbance of the filling material from changing. The melted filler should be immediaby used to sew in the pot pouring sealant, flush with the road surface, the excess material with the shovel tip bance, to keep driving comfort.
