Shandong Hipper Pipe Industry Science and Technology: Common Problems and Solutions of Polyurethane Thermal Insulation Pipe

1.在秋夏季节或许是晚上施工时，由于气温偏低或忽然降低，聚氨酯保温管道的起发速度变慢，这不只影响施工进程，更影响整个工程质量。处理方法就是讲环境温度和黑料温度共同进步即可。经历证明，黑料温度进步到30—60℃，环境温度上升到20—30℃就可保证施工顺利停止。

1. During the construction in autumn and summer, the starting speed of polyurethane insulation pipeline becomes slower because of the low or sudden decrease of air temperature, which not only affects the construction process, but also affects the quality of the whole project. The treatment method is that the ambient temperature and black material temperature can be improved together. Experience has proved that the construction can be stopped smoothly if the temperature of black material is improved to 30-60 C and the ambient temperature is increased to 20-30 C.

2.与一个成绩相反，是保温管道起发速度快，这种景象普通呈现在春夏气温较高时节或半夜施工现场，是气温忽然降低带来的后果。处理方法就是用冷水冷却黑料，或许提早将管道放在室外停止自然冷却，并防止太阳直晒。

2. Contrary to the first achievement, the starting speed of thermal insulation pipeline is fast. This phenomenon usually appears in the spring and summer when the temperature is higher or in the middle of the night construction site, which is the result of the sudden decrease of temperature. The treatment is to cool the black material with cold water, perhaps by putting the pipes outdoors a day earlier to stop natural cooling and prevent direct sunshine.

3.是聚氨酯保温管道泡沫强度小且软，这是由彩色料比例失调形成的。工人可以适当增大黑料比例，依照1:1-1.05，但也要留意黑料比例不能过份增大，否则泡沫变脆，异样影响管道功能。

3. is the polyurethane insulation pipe foam strength is small and soft, which is caused by the imbalance of color materials. Workers can appropriately increase the proportion of black materials, according to 1:1-1.05, but also pay attention to the proportion of black materials can not be increased too much, otherwise the foam will become brittle, and affect the function of pipes.
