ANALYSIS OF POLYMER-BASED QUENCHING MEDIA

The characteristics of quenching liquids such as oils and salt and pol ymer solutions can change during use because of impurities, degradatio n, or other causes. In this connection, desirable results in quenching are obtained by periodic control of the composition and properties of the quenching medium. The method for analyzing oils is quite develope d, whereas no similar method for analyzing quenching media based on wa ter-soluble polymers exists, although they are becoming widely used in industry. The article concerns the properties of aqueous solutions of polymers and methods for their determination.
