April, five RA2-7 from the 19 th can not afford the viscosity has been dismal: The target viscosity of 5800, each batch of washed up only 6100, this data was very information. Nerve stretched too tightly so that everyone, has been worried that the viscosity is not on the rise. If the viewer is not aware, the viscosity is not on the rise, UAS has been added to jump off the high limit, then it is possible to isolate this batch of liquid or discharge, direct economic losses caused by industrial accidents.

 For RA2-7, Xia and Zhou Qingjing made ​​to add the amount of each batch of data analysis, running multiple viscosity scrub, a variety of observation and analysis of the possibility of internal leakage. Also includes the plant's director of RA1-7 PTG segment of water testing, all no problem. On April 20, the day shift did not occur on a number of viscosity rise caused UAS adding high limit and temperature anomalies of the accident, but the second has been aggregated. To this end, Dong Ah plant and process engineers to run also came to the scene, waiting for the batch of liquid decisions in isolation. Although the UAS to the high response time limit exceeded, but the viscosity or the rose in force under the 5800, but also on the RA2-7 viscosity and low molecular weight, D-MTK viscosity detection analysis, data normal, OK, you can normally use , We sigh of relief.

 Viscosity rise on a variety of possibilities is not done, in the end is why it? Only have access to previous cases, the original RA2-4 are due to mechanical seal leakage on the viscosity of the case do not rise. RA2-7 again to re-close contact, hand in RA2-7 mechanical seal at the touch, surprised to find only slight mechanical seal leakage, the case finally get to the bottom. So the mechanical seal with a clean towel, the next batch of PPS when they transfer and the transfer of mechanical DOPE strict secret rub. The next day repair white flight to adjust the mechanical seal. Polymerization, the maximum viscosity rushed to the 6600, a group of slowly higher than the number of dash, and now are rushed to the 6900-7000 batch between.

 Paper come Zhongjue, knowledge from this practice is essential. Write only know when he was studying chemical equation balancing equation, but now I know the reaction conditions are so strict, including the air has a great impact on the viscosity, damn mechanical seals, mechanical seal fatal, we can not let you make trouble.
