Corrosion of stainless steels in the dimethylformamide media of polyvinyl chloride fibre manufacturing

  • 105 Accesses


The effect of individual components, temperature, and the gas medium on the corrosion properties of dimethylformamide media in the manufacture of polyvinyl chloride fibre has been investigated. It has been shown that the corrosive activity is caused by the joint action of chlorides and the acid components of the technological media. The corrosive activity of the media rises with increase in temperature and depends on the conditions of existence of the gas phase.

In the case of the stillpot liquid, the mechanism of DMF hydrolysis in closed and open systems has been studied. It has been found that in a closed system hydrolysis of DMF is inhibited by the dimethylamine released. In an open system, inhibition of the hydrolysis does not occur. A specific effect of sulfuric acid on the hydrolysis of DMF in an open system has been found.

The corrosive activity of media in the most corrosive-hazardous sections of the technological scheme in operating manufacture is considerably reduced by the introduction of measures to reduce the acid and chloride content of the technological media.
