    PVC is the second staple plastic products in the world, and its demand is increasing year by year. As a new type urgent terminator of PVC, in an emergency of PVC production, NO can rapidly be filled in the reaction kettle and combined with PVC monomer effectively. Consequently,it may rapidly terminate the reaction in the kettle and prevent giving off too much heat to lead to exploration. It ensures the health and safety of all staff. As an urgent terminator of PVC, this NO can become a new trend.
In July 2007, our program “New-Type Urgent Terminator of PVC---NO Gas” became an application for the State Torch Program. This project began in July 2007 and ended in July 2009. This program successfully developed NO gas of 99.9% purity and filled the blank in the country. The product performance index has reached international advanced level and the quality can meet the needs of PVC production. The specific indexes are as follows:
Product Purity: NO≥99.9%
Impurity Content: N2≤600ppm,NO2≤50ppm,N2O≤200ppm,CO2≤150ppm
The success of the project improved the techniques in special gas industry and the filed of new materials. This NO can take the place of the liquid type termination agent we used in the past and make a good effect. And this project played a positive role in ensuring the production safety and improving the performance of PVC,which benefits the society greatly.
