Described drift is to take the hemispherical ferrule that radius prepared by particulate metal is 15.88mm, and weight is connected as a single entity.
Described weight is to be about 1.55m, has the cylindrical, massive metal cylinder of certain radius, can do the movement of falling object by adjacent cylindrical shell, and weight and drift and weight push rod are fixed together, and the gross mass of weight and drift and weight push rod is 1.8kg.
Described weight push rod moves up and down to control the height of drift in mobile recessed joint, and when drift contact test plate (panel), in same level line, can read by the position of weight push rod the distance of drift and test plate (panel) the zero point of weight push rod and Position Scale.Described weight controller can be when weight be raised be fixed during to any part motionless, just free-falling of weight while pressing weight controller.
Described shock point frisket is the square thin plastic sheet that a length of side is 10cm, plastic sheet is divided into the square grid that 25 length of sides are 2cm, in each square grid centre, there is the aperture that a diameter is 2mm, for the particular location of each shock point of mark.
Advantage of the present utility model and beneficial effect are: filled up ultra high build coating, the blank that the multiple spot of resistance to high strength of the special materials such as plastics impacts, can conveniently measure the performance of the multiple spot of the resistance to high strength impact of tested coating, can, with making the maximum impact energy that coating is intact represent the performance that its single-point of resistance to high strength impacts, also can represent with simple and clear coating serviceability rate its multiple spot of resistance to high strength impact property.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the concrete technical scheme of implementing of the utility model is a kind of paint film multiple spot of resistance to high strength impact test instrument, equipment mainly comprises base 11, tower cylinder 1, weight 4 with drift 10, test plate (panel) 9 and shock point frisket 13 forms, and base 11 is provided with test plate (panel) fixed cross beam 7, several set bolts that can rotate up and down 6 is installed for fixing test plate (panel) 9 when the impact experiment on crossbeam.Tower cylinder 1 is that a kind of hollow cylinder is firmly fixed on base 11 by tower tube stent 5, tower cylinder front has Position Scale 3 to be used for showing that drift 10 is apart from the height of test plate (panel), left surface has a mobile recessed joint 12 to make to be fixed on weight push rod 8 on weight 4 from top to bottom can to operate weight and move up and down, tower cylinder 1 right flank is weight controller 2, can allow weight stop at any height or allow its Vertical Free fall.
First experiment is pressed in shock point frisket 13 in the test plate (panel) coating preparing while starting, prevent relatively moving between them, 25 duck eyes that see through on frisket mark 25 shock points in coating, then remove frisket, after fixing test plate (panel) with bolt, shock height is transferred to 1.2m place, with the shock point that it is good that drift is aimed at these 25 marks successively, carry out impact experiment, concrete order as shown in Figure 5.The loose coating of use jack board cleaning loss of adhesion after impact completes, as the chisel of 2.5cm or small scoop, the dynamics of cleaning shock zone should be more a little bit smaller than the dynamics in region between cleaning shock point.The assessment of the coating multiple spot of resistance to high strength impact property is generally undertaken by description below: between every 2 adjacent shock points, have 1 join domain, between 25 shock points, have 40 join domains, if little chisel can be by the one or multi-channel coating removal between 2 contiguous shock points, cause these 2 shock points to communicate, the serviceability rate of coating declines 2.5%, the like.If there are 4 impact points to communicate, the serviceability rate of coating is 90%.Also can preset the technical indicator of a coating serviceability rate, result with by or obstructed coming represent.
The resistance to impact of measuring coating single-point is similar with the shock-resistant determination method of GB/T1732-1993 paint film, and the maximum impact energy value that can not be damaged by a coating represents the impact resistance of coating.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
