Embodiment Construction

[0009] In the cylindrical glass box (1), the variable temperature resistance wire (5) is laid on the bottom of the cylindrical glass box (1), and the power supply control module (6) is located at the center of the bottom of the cylindrical glass box (1). The electric fan (8) is located between the power supply (6) and the ultraviolet lamp (10), and is fixed on the iron central shaft (16). The upper part of the hook (14) passes through the center point of the sealing cover (13) and is sealedly connected with it, and the lower part hangs the sample hanging plate holder (4) so ​​that it is centered and suspended in the cylindrical glass box (1). The sample plate (2) is suspended on the sample hanging plate frame (4). The sealing cover (13) is located at the top of the cylindrical glass box (1), and can seal the cylindrical glass box (1). The refrigerator (11) is located on one side of the top inner wall of the cylindrical glass box (1), and the humidifier (12) is located on the ...

Abstract

The invention relates to an experimental device for accelerating aging of paint. The experimental device is composed of a cylindrical glass box, a sample plate, a detector, a sample hanging plate frame, a variable-temperature resistance wire, a power supply control module, a valve, an electric fan, a gas collecting bottle, an ultraviolet lamp, a refrigerator, a humidifier, a sealing cover, a hook, a guide pipe, a plug with a conductor wire, an irony central shaft, a ventilation pipe and a plug with a conductor wire. The problem that air cannot flow in a square dead angle can be avoided through the cylindrical glass box; the weather resistance of the paint under natural conditions and extreme weather can be determined by accurately simulating various influence factors; and the experimental device for accelerating aging of the paint is simple and easy to operate, has obvious aging simulating effect and can achieve an accurate determination result.

Description

technical field [0001] The invention relates to an accelerated paint aging test device, in particular to a simple and simple simulation device capable of simulating natural conditions and extreme weather and having accurate measurement results. Background technique [0002] With the growing prosperity of decoration companies, paint has become an indispensable decorative and protective material. However, the weather resistance of paint has attracted widespread attention, such as acid resistance, alkali resistance, smoke corrosion resistance and Freeze resistance, etc. At present, there are three main methods to study the weather resistance of paint: natural exposure test method, outdoor accelerated aging test method, artificial aging test method, artificial aging test method is often used xenon arc radiation method and ultraviolet light aging test method, natural exposure method It will be seriously affected by the season, and most of the detection devices are square, with l...
