The gravel resistance test machine is mainly used to accurately reproduce the phenomenon of splattered gravel. It is suitable for the adhesive destruction test of the outer coating adhesion, the bonding destruction test of different layers in the coating system, and the hard The brittleness thickness of the glass material, the thickness of the coating film, the anti -peeling, anti -collision, and anti -abrasion test of plastic and glass. It is a test equipment independently developed and produced by Shanghai QINSUN Precision Electrical Technology Co., Ltd., with high cost performance.
Testing principle:
Get piercing impact test machine is a multi -impact instrument. Its advantage is that the result is good and comparable. The sharp particle impact model, the instrument's own air storage tank can reduce the impact of the instantaneous pressure fluctuations of the external compressed air, to provide a constant impact pressure, and use vibration to feed the particles. Multi -motion display can display work pressure, test time, vibration feeding particles and the number of impact times.
Main technical parameters:
01. Work pressure range: 0 ~ 5.0kgf/cm2/level 1.6, 1.6, 1.6, 1.6, 1.6, 1.6, 1.6, 1.6, 1.6, 1.6, 1.6, 1.6, 1.6, 1.6, 1.6 It can be adjusted according to the actual gas source pressure of the customer, and it can reach 8.0kgf/cm2
02. Compressed inner diameter of the air pipe: 19mm or larger
03, air slot capacity accumulation: 180L can be satisfied: When opening the magnetic valve, the work pressure of 400kPa (4BAR) can continue to maintain at least 10 seconds
04, feeding method: automatic feeding, feeding speed can be adjusted
05 , VDA spray gun: 30.0 ± 0.5mm
