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

Tinuvin 1130: An Excellent UV Absorber

 In the field of the chemical industry, UV absorbers play a crucial role, particularly in protecting materials from UV damage. Today, we will delve into a highly regarded UV absorber—Tinuvin 1130. Tinuvin 1130 : chemical name: 3-(3-(2H-benzotriazole-2-yl)-4-hydroxy-5-tert-butyl phenyl)propionic acid polyethylene glycol 300 ester; CAS login number: 104810-48-2. This product is an exceptional UV absorber that offers numerous benefits due to its unique properties. One of the standout features of Tinuvin 1130 is its excellent weather resistance. It has a strong ability to absorb ultraviolet rays, particularly those with wavelengths ranging from 290-400nm. This effectively prevents coatings, plastics, rubber, and other materials from being damaged by UV rays, thereby maintaining the performance and appearance stability of these materials and extending their service life. In addition, Tinuvin 1130 exhibits good compatibility. It is easy to emulsify in water-based systems and can be...

Mechanism of action of benzonitrile

  Product identification： Product name:  Benzonitrile Molecular formula: C7H5N CAS No.100-47-0 Benzonitrile is a colorless oily liquid with an almond-like odor. It is slightly soluble in cold water, soluble in hot water, and easily soluble in organic solvents such as ethanol and ether. The mechanism of action of benzonitrile can be elaborated from the following aspects: I. Chemical Properties and Applications As an Intermediate in Organic Synthesis: Benzonitrile plays a crucial role in chemical synthesis as an intermediate for many important compounds and materials. For example, it can be used to synthesize advanced coatings such as phenyl melamine, as well as compounds such as pesticides, aliphatic amines, and benzoic acid. These compounds have a wide range of applications in agriculture, coatings, plastics, and other fields. As a Solvent: Benzonitrile possesses good solubilizing properties and can be used as a solvent. In organic synthesis, it is often used as a solvent to d...

Air-cooled Xenon Lamp Aging Tester

  The air-cooled xenon lamp aging tester is a device that uses an air-cooled system to dissipate heat and a xenon lamp to simulate ultraviolet light, visible light and infrared light in natural sunlight to perform accelerated aging tests on materials. It is commonly used in industries such as automobiles, coatings, plastics, rubber, and textiles. It can evaluate the aging resistance of materials under the combined effects of long-term light, temperature, humidity and other environmental factors in a relatively short period of time, helping companies improve product quality, extend service life, and optimize product anti-aging formulas and processes. Structural composition:  The main body is a test chamber, equipped with a xenon lamp and a matching optical filter system to simulate sunlight of different wavelengths, as well as temperature, humidity, lighting time and other control and adjustment devices, as well as an observation window and a sample rack. Working principle: The...
