National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Whole Glove Permeation/Penetration of Organic Liquids with a Dextrous Robot Hand.

PB2015100628

Publication Date	2014
Personal Author	Que Hee, S. S.
Page Count	128
Abstract	Original Achievements: 1. Development of a dynamic flow system for whole gloves on a dextrous robotic hand that is capable of continuous or intermittent sampling of water soluble chemicals that permeate through gloves. 2. Development of a whole glove dextrous robotic hand model, nonmoving and clenching, that was compared with the standard ASTM F739-99a permeation closed loop method for four different disposable glove nitrile materials using the nonvolatile solvent cyclohexanol. 3. Development of calibrated sensitive instrumentation to test for the presence of microholes. 4. Generation of the first porosity data for disposable gloves. 5. Measurement of normalized breakthrough times, lag times, steady state permeation rates, and diffusion coefficients of selected chemicals through 4 different disposable nitrile materials, the results showing that thicker gloves allowed greater protection than the thinnest gloves for a specific chemical. 6. Discovery that robotic hand clenching for whole glove permeation causes more permeation and earlier breakthrough for the thinnest glove but not for the thicker gloves. This is suggestive of a necessary balance between worker comfort/capability of manipulating objects and safety considerations. 7. The protection afforded by double gloving is more than double relative to both normalized breakthrough time and steady state permeation rate.
