Detailed introduction:

High and low temperature gravel impact testing machine

Equipment Profile:

The Organic coating Committee of the Automotive Engineering Association has been developing rock shock since 1986 to test and identify the resistance of automotive materials to rock fragments.

Resistance of high and low temperature multi-function gravel impact testing machine is mainly used to accurately reproduce the broken phenomenon, caused by flying gravel multi-function gravel impact testing machine is suitable for the external coating resistant adhesiveness destruction test, coating adhesive properties between different layers in the system test, the rigid glass material brittleness and spalling of the optimal coating thickness, plastic and glass of spalling resistance, impact resistance, resistance to abrasion test and related test.

The damage degree of the coating is caused by the single-layer, multi-layer and even all the flaking of the graded coating at the injection Angle and pressure.

The blow of macadam, the quality of steel shot or macadam, impact duration and test instrument not only can make the decorative effect of coating suffer loss, but also can affect the setting condition of coating and so on to decide jointly.

Meet the following test criteria:
