Carbon fiber / PTFE mixed filler should look pattern are known, smooth, impregnated with PTFE emulsion or other lubricants should be evenly distributed and should not fall off, the exposed thread, jumpers, missing flowers, Le Edge not more than one 10m.

Test Method

Carbon fiber / PTFE mixed packing specifications and tolerances square cross-section, with an accuracy of 0.02mm vernier caliper from two mutually perpendicular directions measured from any point of the filler as a starting point, measured once every 1m, take three at the measurement result as the arithmetic mean.

Carbon fiber / PTFE mixed packing bulk density, compression rate, spring rate, Mocha coefficient of the amount of wear, the amount of detected temperature, according JB/T6371 requirements.
