Lamp Aging Test Chamber

Analysis of the 4 most common failures of UV Aging Test Chamber UV Aging Test Chamber  common failure analysis: 1, the instrumentation failure rate is high. Fluorescent UV Aging Test Chamber instruments are installed on the top of the equipment, so there is a problem: in the equipment for heating work (sometimes a test will do a few days, or even weeks, the laboratory temperature can reach 60 ℃) and some laboratories do not install air conditioning, and the heat is going up, so the instrument will suffer the ravages of high temperature for a long time, in this high-temperature environment, the instrument is prone to failure. 2,, the water tank heating tube replacement frequently. Because there is no deionized water as required, so the heating tube long-term immersion in tap water, high-temperature tap water. We all know that the heating tube is made of stainless steel tube filled with magnesium powder. So long-term heating work in tap water, will lead to corrosion of the surface of...

Salt Spray Test Chamber3 types of salt spray acidity and alkalinity preparation 1. Weak acid salt spray test (NSS test) corrosion resistance configuration:) The pH is adjusted according to the amount of sulfuric acid and NaOH added. Because the pH of neutral salt spray is manipulated in the middle of 6.3-7, measuring pH can use acidity meter, also can use hardware mechanical pH pregnancy test paper (accurate measurement precision within 0.5pH) 2. Acetic acid salt spray test (AASS experiment) corrosion resistance configuration. According to the amount of glacial acetic acid and NaOH added to adjust the ph pH. Because the acetic acid corrosion resistance pH manipulation in the middle of 3.2-3.2, therefore, measuring pH can be used acidity meter, but also hardware mechanical pH pregnancy test paper (accurate measurement precision within 0.5pH)

xenon lamp aging test chamber lamp rupture cause analysis 1. not used for a long time, the closed end aging, resulting in fracture. 2. unreasonable design of the air duct, the terminal is right next to the metal of the lamp shade. 3. Design problems, resulting in the closed end of the fan contact with the metal, the closed end melted and metal short circuit, the fan does not rotate, resulting in the heat of the lamp can not be dissipated. 4. After the use of the lamp, the surface may accumulate ash and oil, more than a year after the boot is not clean, which may lead to an increase in surface temperature when heating, instant uneven heating and rupture.

The 4 hazards of salt spray corrosion test  China's annual economic loss caused by corrosion of at least 20 billion. The great harm of corrosion is not only reflected in the economic loss, but also brings significant casualties, environmental pollution, waste of resources, impede the development of new technologies and promote the loss of natural resources. The background and mechanism of salt spray corrosion. It is caused by the environment of corrosive substances or the destruction or degradation of their properties. Most corrosion occurs in the atmospheric environment, which contains corrosive components and oxygen, humidity, temperature changes, pollutants and other factors. Salt spray corrosion is a common and destructive atmospheric corrosion. Salt spray refers to the chloride atmosphere, and its main corrosive component is sodium chloride. Salt spray corrosion on the surface of metal materials is caused by the electrochemical reaction of chloride ions through the oxidation l...

How do I determine the test time for the Xenon Arc Weatherometer? SOURCE: Xenon Arc Weatherometers  reproduce weathering damage by sunlight, temperature, humidity and water spray.    When Xenon Arc Weatherometer is in operation, customers often want to know how long the accelerated weathering test should be conducted to correspond to 5, 8, 10 years, etc. It can be clearly said that there is no such correspondence, which is due to the diversity of materials, the diversity of material formulations, climate diversity and many other complex factors, and the conditions of the Xenon Arc Weatherometer test are relatively fixed, but it is just a number of cycles of the same test conditions. So, what to do at this point? There are several methods for reference. 1, refer to the relevant product standards   Many products or materials manufacturers have made provisions for the aging test time in their product standards, we just need to test according to the standard time and con...

What is the function of the Xenon lamp aging test chamber's Xenon arc lamp cooling unit? In order to cool the Xenon lamp aging test chamber of the xenon arc lamp, with distilled or deionized water at least 378.5L / h flow through the lamp components. To prevent contamination and reduce deposit formation, the water can be purified with a mixed-bed deionizer close to the front of the lamp. The recirculating cooling water of the arc lamp is cooled and prevented from contamination by a heat exchanger, which can be used as a heat exchange medium with tap water or refrigerant. Standard use of Xenon lamp aging test chamber device is equipped with a countdown timer to control the exposure time. Some devices are also equipped with a burst light monitor, so that the preset radiation exposure is reached as soon as the device is shut down. Temperature and humidity control: Since some plastics are temperature sensitive, accurate and tight control of temperature is essential in tests conducted i...

UV Accelerated Weathering Tester common 4 failure analysis UV Accelerated Weathering Tester is suitable for the aging test of non-metallic materials against sunlight and artificial light. 1, UV sink rust through The sink is used to fill with water for heating, simulating a condensing environment at night in nature. Sink is made of stainless steel, so in the use of equipment, if the user does not follow the prescribed method of adding deionized water to the test, but to join the tap water, will lead to the use of equipment after about 3 years, the formation of substances corroded by water heating, resulting in rusting sink, until the sink and other rust through. 2, ultraviolet lamp point does not light UV lamps in use, some times the lamp does not light up. This is because the fluorescent  UV aging test chamber  is generally used are electronic ballasts, electronic ballasts are wired for the jack type. So limited by the details of the production process, it will lead to the lam...
