Main Technical Parameters
Test chamber inner dimension | W500XH600XD500mm |
Test chamber Temperature & Humidity | Temperature control range: 0℃~70℃ adjustable Temperature uniformity: +/- 2℃ Humidity control range: 20%RH~90%RH adjustable |
Ozone concentration | 10~1000pphm +/- 10% pphm adjustable |
Ozone gas flow velocity | 12~16mm/s |
Velocity of ozonized air | 600mm/s+/- 100mm/s |
Test time | 0~999H/M/S |
Dynamic testing device | Turnable sample rack stretch frequency: 0.5Hz Sample stretched cyclic between 0 to 10% or other specify stretch ratio Continuous or intermittent dynamic stretching available Sample rack rotating rotates at the specified speed available |
Static test device | After the sample is stretched by 20% or other specified ratio, it is fixed on the sample holder, and the sample holder is rotated at a specific rate to fully expose it to the specified ozone gas. After reaching the predetermined time Observe whether the surface of the sample is cracked |
Sample rack rotating velocity | 20mm~25mm/s or adjustable at will |
