Stability of a membrane sheet in superheated water

Stability of a membrane sheet in superheated water. Rakhman, M. Z.; Malkina, L. B.; Vakorina, M. V. (LF, NIIRP, USSR). Kauch. Rezina, (11), 27-9 (Russian) 1984. CODEN: KCRZAE. ISSN: 0022-9466. DOCUMENT TYPE: Journal CA Section: 39 (Synthetic Elastomers and Natural Rubber) Section cross-reference(s): 40, 42 The resistance of rubber-coated membranes to superheated water (125-150°) depended on the impregnating material for polyamide fabrics and the type of the vulcanizing system. Thus, membranes manufd. from aliph. or arom. polyamide fabrics impregnated with L-19F [24969-11-7] or E-89 [26335-32-0] resin, pretreated with SiO2 compn., coated with SKN-26M skim stock and vulcanized with a system contg. peroximon F-40 [2781-00-2], p-quinone dioxime [105-11-3], Fe3O4, and carbon black, exhibited the highest resistance to superheated water. The rubber coating protected the polyamide fibers of the membrane against hydrolysis.
