A,purpose

Coating strength, hardness, adhesive force is the important physical properties of the film, an important performance, which directly affects the size of the film for example: wear resistance; abrasive resistance; scratch resistance; retention and cleaning impact resistance and coating difficulty, so the coating strength, hardness is the evaluation of coating performance the index will be measured. The use of this instrument can facilitate the comprehensive evaluation of coating strength, hardness, adhesion and other physical properties, so the instrument used for film coating by model by stylus ruled penetration ability to characterize the size of the coating hardness, adhesion strength, size.

This instrument is for carrying outGB9279-88And the development of special equipment, is the condition of the implementation of the national standard.

Two, the working principle of the instrument

This instrument is mainly composed of a stylus frame and a worktable, stylus frame of the stylus role in the film the vertical pattern (the sample is fixed on the bench experiment table, can be horizontal or vertical movement; lateral movement can maneuver can also be manually in power off after the longitudinal movement for the manual).

After the power supply is switched on, the red indicator light of the power switch shows that the instrument power is switched on. If the return switch in the experimental state, work table by moving right to left stylus in the "experiment" travel and contact model; return stroke (return switch back to "return"), table moving from left to right, stylus is lifted without contact model, transform stylus rack with weights that can be measured in different weight can cut the film, the minimum weight required for the film cut to determine the value of anti cut film.

Three,Main technical index

1The needle length is not less than60mm 2Test bed movement speed:20 - 40mm/s

3Needle ball diameter1mm 4Dip angle of the lower end face of the top bar:10 - 15DEG

5And the weight loading range:0 - 2000g 6Minimum increment:50g

7Working voltage::220V50HZ 8Power consumption:15W

9Weight:10Kg 10Shape dimension:180*230*280mm

Four, the use of requirements

1Coating template: PressGB9271 - 88Preparation, specification for:120*50mm

2Experiment environment: temperature23.2DEGC, relative humidity:50.5%(refer toGB9278 - 88)

Five, operation and use of the method

APreparation

1According to theGB1727 - 79Require preparation120*50mm(0.2 - 0.3mmThick) smooth or according to the requirements of the tinplate exhibits floor preparation of paint film.

2Inspection instrument

(1Switch on the power ()220V)

(2) press the switch (power switch) and a toggle switch to "experiment" stroke, transverse Mobile Test (left) to the left stop, and then toggle switch to "return" stroke, transverse Mobile Test (right) to the right end stop. Note: the toggle switch middle position urgent stop".

(3(according to the monitoring of twisting (point) power meter pointer, while the indicator light is on the normal.

3In the installation of a new needle into the needle, the needle should be used30Magnification endoscopy needle should not have scratches, rust and other defects, park, stylus installation height should be appropriate.

4The model test bench, with sample holder, coating upward rotation vertical handle so that the test bench to the distal (test bench and table level) for the initial position.

5And put the smallest weight on the platform.50g) or to plan broken film smaller weight.

BTest

1And the work button switch to "experiment", stylus on the block is cut across, observed by eyes, such as cut, pointer, and cut the indicator lights, if not cut, pull the switch to "return", the test returns stopped at the right end of the handle and fretting longitudinal movement (forward precession) to test mobile point (draw second scratches do not overlap can be on the first scratch), but also to draw the needle change for a new examination method for the same, and in the weight table for a heavier weight level which do everything well prepared draw second scratches.

2Repeated the test, until the film was cut (at the same time the meter is lit and the meter pointer is also available.10Doubling the magnifying glass to observe whether the scratch of the film is exposed to the bottom plate, the length of the cut part of the scratches should be greater than20mmWeight: the weight of the weight of this time is the paint film resistance (measured value of the method).

3And the determination of load on the original model and a new model of the same two repeat the test steps and the results were consistent, is determined to cut through routing model, the minimum load value is the value of anti scratch coating.

When the measured load value is not at the same time, the average value of the load value of three times is the value of the film.

Six, maintenance:

1The use of the instrument, sought to be flexible rotation, should pay attention to lubrication (oil should be injected between rotating parts and rotating parts and relative motion components);

2And the instrument in use for a period of time, to fully check the fasteners to prevent loosening;

3When the instrument is not used, it should pay attention to dust, moisture, corrosion protection, avoid vibration and collision.

Seven, accessories
