Technical information:
Rubber Content of "Paishun's Hose" - The NBR Content of Hose Inner Tube is 42% and 40% in Hose Outer Tube.
The High NBR Material Content makes the Hose has excellent "permeability", so the Hose is able to not " bulge" even being immersed in High grade gasoline after 72 hours.
The Electrical Conductivity of Hose Assembly - When our workers do the assembling, we'll make sure that the Connectors to be well connected to Hose Wire, to make sure the Hose has "stable conducting electrostatic property", we test the " Hose Electrical Conductivity" with Ammeter.
Pressure Test - Every batch Hose will be tested under the Test Pressure (10times higher than the Hose's W.P.) and keeps at least 3 minutes, this is to avoid any invisible holes appear on Hose.
The Wire we use - The tensile strength of Single Wire we use is 2750 Newton high strength wire, the wire diameter is 0.295mm.
The " TEST" we do for every batch of Hose:
1) Test the " adhesiveness" between wires and rubber. Every batch of wires will be tested.
2) Test the " break strength" of wire. The standard wire we use is 2750N, we will test the " strength " of every batch of wire.
3) Test the " Pressure" of Hose, evey roll of Hose will be tested.
4) Test the "rubber sheet break strength" and " rubber sheet elongation at break".
5) Test " rubber wear-resisting property "
6) Test " rubber aging resistance "
7) Test " ozone resistance ".
8) Test " low temperature resistance ".
9) Test " hose electrical conductivity ".
10) Test " bending properties".
11) Test " incombustibility".
