Description
Technical Field
The utility model relates to a laboratory instrument makes the field, concretely relates to hot damp and hot and corrosion-resistant testing arrangement of lacquer membrane.
Background
The resistance to damp and heat and the resistance to corrosion by saline water media of the metal paint film are two very important properties, and if a better paint film state can be kept under a harsh test environment, the excellent protective performance of the product can be ensured.
The conventional damp heat test is performed in a heated constant temperature water bath, and the temperature can be set by the constant temperature water bath, and the test is performed under the harsh condition of 50 ℃.
Brine corrosion resistance is typically tested by soaking the painted metal sheet directly into a brine seed. However, different plates must be used for testing, and the existing salt water resistance test is usually only used for testing the condition at room temperature. This results in non-uniform temperature conditions for testing and cumbersome testing equipment.

Detailed Description
The paint film heat, humidity and corrosion resistance testing device 100 shown in fig. 1 comprises a water storage cavity 110 for storing water, and a heating pipe 121 of a heating device 120 extends into the water storage cavity 110 for heating the water in the water storage cavity 110.
A paint film detection container 130 is arranged in the water storage cavity 110, specifically, a paint film detection container support frame 111 is arranged in the water storage cavity, the paint film detection container 130 is arranged on the paint film detection container support frame 111, and a plurality of through holes 111a are formed in the paint film detection container support frame 111.
The height of the entire water holding chamber 110 is 40 cm, and the installation height of the paint film detection container support stand 111 is 25 cm.
The metal plate support frame 140 is installed inside the paint film detection container 130, the metal plate support frame 140 comprises metal plate support frames 141 and 142 which are oppositely arranged, a support space 143 is reserved between the metal plate support frames 141 and 142, and the metal plate 200 to be detected is installed in the support space 143. The supporting space 143 has a length of 12 cm and a width of 6 cm.
After the metal plate support frames 141 and 142 are installed with the metal plate 200 to be detected, the paint film detection container 130 is divided into an upper cavity 131 and a lower cavity 132; the height of the upper chamber 131 is 10 cm, and the width of the paint film detection container 130 is 30 cm. The bottom of the paint film detection container 130 is provided with a plurality of through holes 133.
In addition, a movable cover 134 is arranged at the upper part of the paint film detection container 130 for convenient use.
The utility model discloses a theory of operation lies in:
firstly, a metal plate 200 to be detected is arranged in a supporting space 143, the paint film detection container 130 is divided into an upper cavity 131 and a lower cavity 132, then the movable cover 134 is opened, saline is added into the upper cavity 131, then the heating device 120 is started after water is added into the water storage cavity 110, and the water enters the lower cavity 132 after penetrating through the through holes 111a and 133. The paint films of the same test metal sheets were tested simultaneously for resistance to wet heat and humidity of the bottom paint film and for resistance to salt water corrosion of the upper paint film. The hot steam generated by the heating of the bottom part can heat the brine at the upper part, and the outside of the device 100 can be subjected to heat preservation according to actual conditions.
