Test parameter management provisions of Shenzhen Qiyu silicone hose is mainly from the following several aspects to explain
Tensile test
With a hand pulling silicon hose without obvious deformation or elongation, no cracks and 3 times back and forth after bending, silicone tube skin without anywrinkle.
Flame resistance test
Silica gel tube flame lit in the state under, from natural extinguished after 5S.
Adhesion test
The tested silicone tube 180 degree repeated folding 3-5 times, then the voltage withstand test.
High temperature resistance test
Take the tested silicone tube 1-2m tunnel furnace (120 DEG C for 45 minutes),the surface shall not have bad yellow, bubble appearance, again
The silicone tube after high temperature withstand voltage test, and meet thepressure requirement.
The high voltage test
The tested silicone tube sampling, sample (tensile strength after high temperature, bonding force test, test, and then the corresponding (conductor)
Copper or iron) by silica gel tube, take the withstanding voltage tester voltagerod end in contact with the conductor, and the other end through the conductoron the silicone tube
Moving back and forth, when the silicon tube breakdown tester sends out the alarm sound is unqualified, whereas for qualified products.
Silica gel tube voltage requirements are as follows:
Dimensions (mm) voltage value (V) leakage current (mA) voltage time (s) strikeperforation (m)
Phi = 3.525001 1-3 no
3.5 < Phi < 4.825001 1-3
Phi = 525001 1-3 no
