Commercial Possibilities of Rubber-Electrodeposition Process 270026

ACTUAL production-equipment for making rubber goods by the anode process has not been installed and studied to yield accurate quantitative data, but laboratory work has been begun in Akron, Ohio, and although some of the facts learned cannot be discussed by the author at this time, enough general indications have been secured to lead to belief that widely varied and valuable applications of the process will be made.
Factors that influence the commercial application of any process are enumerated and the properties of rubber that the technologist usually studies to determine its suitability for specific uses are listed. Thorough comparison of anode rubber with the milled product has not been made but confirmatory experimental evidence supports belief that the process must yield stronger and tougher material than do current methods of production. The reasons for this are explained.
Other advantages possessed by anode-deposited rubber are superior aging-properties, reduction in the quantity of material used, applicability to the process of dispersed reclaimed-rubber, reduction in size of plant and size and cost of equipment needed, lower labor and power costs, and reduction in waste of material.
The process will be applicable, it is stated, to the various processes of the present rubber-factory, such as making continuous rubber-sheet; forming continuous tubes in long lengths; impregnating fabric with rubber throughout its structure, part way through, or on one surface only; coating metal with a tightly adhering coat of rubber; forming rubber articles of various shapes with uniform wall-thickness or with varied thickness; and making rubber sheets that are thinner than the thinnest that can be calendered.
