Plastic UV accelerated aging test machine

Introduction

UV cycle:

In the process of UV exposure test, temperature control is very important, and more important is to match the test temperature used in the accelerated test

with the maximum temperature of the material in the practical application.

The UV temperature setting in the equipment can be anywhere from 50C to 70ºCC, depending on the level of illumination and indoor ambient temperature.

The temperature adjustment of the equipment is accomplished by a controller with microcomputer function to command a series of systems such as air heater, water heater and so on in the equipment.

Moisture circulation:

As the temperature increases, the destructive power of moisture on the material increases dramatically.

Therefore, in the process of wet exposure, temperature control is the most basic requirement.

Furthermore, to produce an acceleration effect, it is necessary to maintain a high temperature environment during the wet exposure.

The condensation temperature in the device can be set from 40ºC to 60ºC at any point.

Heating system:

U - type high - speed heating tube of titanium alloy is used

Temperature control and lighting completely independent system

The temperature control output power is calculated by microcomputer to achieve high accuracy and high efficiency

It has the function of preventing over-temperature of heating system.

Plastic UV accelerated aging testing machine is a professional equipment with an important position in the field of plastic material research and quality testing.

This testing machine mainly simulates the environment of ultraviolet radiation in nature to accelerate the aging process of plastic materials. It can present in a relatively short period of time the changes that plastics may experience in the long-term natural environment, providing a key basis for assessing the durability and stability of plastics.

Its working principle is based on precisely controlled ultraviolet light sources. These light sources are capable of emitting ultraviolet light at specific wavelengths and intensifies to highly reproduce ultraviolet radiation in nature. By continuously irradiating plastic samples, a series of chemical reactions are triggered, including the break of molecular chains, cross-linking, etc., which leads to the gradual degradation of plastic properties.

Plastic UV accelerated aging testing machine is not limited to simple UV exposure. Many testing machines also have multiple features to more fully simulate real-world environments. For example, the addition of the spray function can simulate the rainy weather, so that the plastic sample is washed by rain, and its aging performance in a wet environment is observed. The addition of condensation function can simulate hot and humid or dew climate, so that condensation water is formed on the surface of the sample, and it is further close to the real use scenario. Such comprehensive simulation ability makes the test results more convincing and valuable for reference.

The stability and consistency of product quality can be ensured by regular aging testing of products. For example, in the plastic packaging industry, the testing machine can be used to evaluate the weather resistance of packaging materials during long-term storage and transportation to ensure product quality and safety.

Coatings, resins, ink paint and other fields are also widely used in plastic UV accelerated aging testing machines. Through the test, we can understand the color change, gloss loss, physical property change and other conditions of these materials under the action of ultraviolet light, and provide data support for product optimization and improvement. In the printing and packaging industry, it can detect the fading, loss of light and other problems of packaging materials to ensure the quality and beauty of printed matter.
