xenon lamp aging test chamber black panel thermometer and black standard thermometer

The xenon lamp aging test chamber is the main test equipment for material aging testing. Our company qisnun Precision Electromechanical Technology Co., Ltd. can provide it. Customers in need are encouraged to inquire. The xenon arc lamp aging test is to simulate the photoaging phenomenon of materials in the natural environment, and the aging factors include temperature, humidity, light and water. The test box should also be equipped with temperature control and measurement devices, and the temperature measurement devices include black panel thermometers and black standard thermometers.

The Black Panel Thermometer (BPT) is a relatively old thermometer that has been in use for decades, and many standards continue to be used . A blackboard thermometer ranmment used is composed of a stainless steel plate. The side of the stainless steel plate facing the light source is covered with a matt black paint. This black can absorb 90% of the total identical light influx in a wavelength of 2500nm. The panel temperature is measured by a rod-shaped bimetallic disc sensor or a measuring resistance sensor which is fixed in the center of the backlit surface of the panel and firmly connected to the black and blackened exposed surface.

Black standard thermometer, the full name is black standard thermometer, called BST. A black standard thermometer is basically a modified black panel thermometer. Its structure and testing principle are basically the same as the traditional black panel thermometer. The main body of the black standard thermometer is also a stainless steel plate, and the surface facing the light source is evenly covered with a coating.he anti-aging black paint, which can absorb 95% of light with wavelength less than 2500nm. A platinum resistance sensor is mounted on the backlight to measure the temperature of the blackboard. At the same time, a detailed design is added to the backlight surface. This backlight surface is also 5mm thick and has a grooved surface nearby, leaving a gap of about 1mm. At the same time, it is also necessary to ensure that the length and width of the entire base are large enough to ensure that there is no metal contact heat transfer between the metal plate of the standard thermometer black installed on specimen holder and specimen. sample holder and the metal frame or support on the sample holder and the thermometer. There must be a gap of at least 4 mm between the edges of the sheet.

In general, the temperature measured by the thermometer isblack alon is higher than that measured by the black panel thermometer, and it is considered that the black standard thermometer is more suitable for measuring the exposure temperature of dark polymer samples with poor thermal conductivity, while the black panel thermometer was also gradually replaced.

As an enterprise integrating R&D, manufacturing, sales, training and service, Shanghai Fanbiao Textile Testing Technology Co., Ltd. is committed to providing more test instruments to the market, long-term supply of textile, leather, combustion test instruments, automotive interior materials, environmental weather aging, masks and protective clothing, etc. can also accept non-standard customization. Before purchase, we can carry out targeted tests according to customer requirements to ensure that the instruments purchased are suitable.
