Gas Permeability Tester For Testing Lab Workshop.
Gas Permeability Tester - For Testing Lab
Permeability of rubber sheets to gases is defined as the rate of
volume flow of gas under steady state conditions between opposite faces
of a unit cube of solid rubber, when subjected to unit pressure
difference under a controlled temperature. The measurement of this
characteristic is of important in the evaluation of compounds for
products such as inner tubes, tubeless tyre liners, hoses, balloons or
other gas containers, seals and diaphragms etc.
The Gas Permeability Tester for
rubber consists of a test cell with arrangement for maintaining a
constant elevated temperature and a horizontal glass capillary system
for measuring the volume of gas permeated.
The test cell consists
of metal blocks having independent arrangements for heating with the
help of cartridge type heaters. The temperature of each ck is indicated
and controlled individually with the help of individual digital
temperature indicators cum coblontrollers. Both the blocks are properly
insulated to avoid heat losses.
