QUALITY COMMENTS
Railcars VIPX 45823 and PLCX 43012 presented isolated moisture problems. The resin appeared to be dry but there were 3-4 incidents which caused problems in the extrusion and blending areas. UTC did a thorough job of checking out potential sources of water in their system and could not locate any. Nonetheless, they had water running out of the bottom of a metal storage bln that holds 6 batches of compound, such as their P-63 or P-90 formula.
CALL SUMMARY
VVV 000008923
UTC first noticed the problem of what appeared to be wet resin when they first saw steam being released from the finished compound. They then switched to a produc tion batch using no lead, thinking that the moisture was a function of the lead, and the problem went away. They then re-entered the same lead and the problem was still gone. Downstream, one of the extruders became rlpgged and an operator was over the feed section when there was an apparent release of volatiles, such as water vapor, which came un_ through the feed__sectlon and blew PVC compound Into the operator's face. He was taken to the emergency room at the hospital. This partlrular incident obviously increased the visibility of the problem, even though the worker was treated at the hospital and released.
UTC did a thorough search of any potential water infiltration, starting with the railcar all the way through their raw material transfer system on the resin, as veil as other microingredients, leading to the mixing area. It appears to be an intermittent problem, but they are very concerned with the originating source,
believing that it was a result of a couple of slugs of vet resin.
