Analysis of the application characteristics of QINSUN UV ultraviolet test box

QINSUN UV aging test chamber application characteristics analysis

 

What is a UV aging test chamber?

UV aging test box is one of the aging test boxes. Ultraviolet aging test box is also called weather accelerated aging test box and ultraviolet aging test box. It simulates UV light and conducts UV tests at set temperatures.

The UV aging test chamber is suitable for the aging test of non-metallic materials to sunlight and artificial light sources.



Eight UV fluorescent lamps rated at 40W were used as light sources.

UV fluorescent tubes, distributed on both sides of the machine, 4 on each side (there are UVA-340 and UVB-313 light sources for users to choose and configure).This ambient climate chamber simulates UV light.


How UV Tester Works？

The UV aging tester uses a fluorescent UV lamp as the light source, and accelerates the aging test of materials by simulating the ultraviolet radiation and condensation in natural sunlight, and obtains the results of material aging.



It simulates UV, rain, high temperature, high humidity, condensation, darkness, and other environmental conditions in natural climates, by reproducing these conditions, combining them into a cycle, and allowing it to automatically execute the number of cycles completed.

The UV light test chamber is suitable for accelerated aging tests of paints, inks, chemicals, rubber, paints, adhesives, etc.

QINSUN Instrument is a professional manufacturer of UV test chambers in China. If you are looking for a suitable UV aging test box, please feel free to contact us and get a UV test box price! Our high-quality UV test chamber is undoubtedly your first choice!


The test sample holder is on the test rack, facing the fluorescent lamp; when the sample does not fill the sample rack, it is necessary to fill the sample rack with a blackboard to keep the interior of the test chamber closed.



test temperature. 50, 60, 70°C for light supply, 60°C is recommended; the condensing section temperature is 50°C, and the temperature tolerance uniformity is ±3°C.


Each light concentrating cycle can provide two cycles of 4H light and 4H concentrating or 8H light and 4H concentrating.


After the first light is on for 400-450H, each row of lamps needs to be replaced with a fluorescent lamp, and the rest of the lamps are based on the lamp cycle and replacement method to compensate for the loss caused by the aging of the lamps. This mode of operation guarantees a service life of each lamp between 1600-1800H.


When changing bulbs, the water tray should be dried and cleaned to avoid limescale formation.

The difference between these two UV aging chambers is

Different number of UV lamps

1. Lamp tubes of tower type UV aging test box: 8 pieces,

2. Box type: tube: 6/8 pieces.

Lamp installation location is different

1. Tower type UV aging box: 4 UV lamps on each side

2. Box type: UV lamp is located at the top of the box top

Test sample sizes vary

1. Sample size of tower UV aging box: 75*150mm, 48 in total, the sample is smaller and can be changed.

2. Box type: can hold conventional or non-standard test samples, such as 400*500mm

Multi-Functional Scratch tester For automotive interior materials

          Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).         Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured.         Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consum...

Reveal the standards for textile breathability testing and let you understand it in seconds!

 Reveal the standards for textile breathability testing and let you understand it in seconds! Breathability testing is a measure of how much gas can pass through a textile. However, there is no single "optimal" air permeability value, as it depends on the specific circumstances in which the textile is used. For example, if it is used to make sportswear, it is hoped that it has good breathability; if it is used to make insulating clothes or warm clothes, it is hoped that it can block the cold well. Therefore, when testing the air permeability of textiles, the purpose of using the textile must be clearly understood in order to obtain reasonable values. In order to accurately and quickly test the true breathability performance of a sample, specially designed and developed instruments must be used. Testing methods generally include: fabric thickness (Thickness), fabric density (Density), fabric water absorption rate (Water Absorption Rate), evaporation and mass transfer (Moistur...

Test Methods of Universal Pilling Assessment Viewer (PAV)

Universal Pilling Assessment Viewer enables fabric to be assessed while still mounted on a Martindale head. The Pilling Assessment Viewer (PAV) for the textile market has been developed with the help of a major textile company in accordance to BN EN ISO 12945 standards incorporating all 3 parts and adopting the following test methods: Part 1: ICI Pilling box method (BS 5811) Part 2: Modified Martindale method (SN 198 525) Part 3: Atlas random tumble method (ASTM D 3512-96) It uses D65 Artificial Daylight (with CWF optionally available), as specified by many retailers. Other test methods can also be viewed, including those specified by major retailers. Other results of test methods that can be viewed include: BS 5811:1986 Determination of resistance to pilling and change of appearance of fabrics. ICI modified pill box for snagging Fleece appearance and surface change after washing Other test methods as specified by several major retail outlet. To optimize c...
