The Properties of Mechano-Chemical Turbine using a Collagen Film

Abstract

The apparatus of mechanochemical turbine in the mechanical shape and materials similar to those designed by A. Katchalsky was constructed. The experiment on the driving of mechanochemical turbine was performed to make clear some obscure points in Katchalsky's paper such as proper condition of crosslinking treatment of collagen film, theoretically induced revolution number and situation of turning. The following results were obtained; 1) crosslinking of collagen film with 2% formaldehyde aqueous solution and 10 M LiBr aqueous solution as a contracting liquid were found to be suitable, 2) the equation of the calculated revolution number using the mechanochemical diagram was induced, 3) this turbine could not be turned continuously for a long period of time, but continuous several turnings were gained temporarily, and it was found that the observed revolution number was 2.5 sec-1 and the power was 26.5 mW closed to the figure of 30 mW obtained by Katchalsky. The results indicate that the induced equation of revolution number is valid and the power of 26.5 mW would be acceptable. © 1982, The Society of Fiber Science and Technology, Japan.
