Four kinds of Sunlight fastness tester structure
Sunlight fastness tester is a xenon lamp as light source, and simulated rainfall, humidity, condensation and climate environment of light aging test chamber, aging can be used to simulate light aging test can also be used for light fastness test experiment, currently has a water cooling, air cooling and the way the desktop three kinds of structure forms and aging, the following is the characteristic of three kinds of structure:
Water-cooled Light Fastness tester:
Water cooling refers to the use of water-cooled xenon lamp tube as the light source, the box structure is standard vertical, because it involves the water cooling of the lamp tube but circulates, there is a circulating water tower device on the top of the box body. The inner part of the test box is placed vertically with a water-cooled lamp tube surrounded by clamping plates. The clamping device is integrated with the bottom turntable to form the test sample frame. The whole structure is a cylindrical structure. Before the test, the sample material is clamped on the sample rack to allow the light from the lamp tube to shine on the sample surface. At the beginning of the test, the turntable began to rotate and the radiation light source began to age.
Air-cooled Light Fastness tester:
Because the power of the air-cooled xenon lamp differs greatly from that of the water-cooled xenon lamp, three air-cooled lamp tubes are adopted in the water-cooled test box to replace the water-cooled lamp, which can save the water tower device and simplify the equipment structure. The three lamp tubes are placed horizontally on the top of the inner bladder and irradiated vertically on the sample surface below. There is no special restriction on the state of the sample material, which is satisfied with the test of various materials.
Box type light color fastness tester:
Continue, box-type timely three-dimensional box type of xenon lamp aging test chamber, with his beautiful appearance design and convenient operation, the internal volume of space and the test environment is open, convenient for observation and test, is also one of the most widely used models, the Atlas xenon lamp weather resistance tester's sales in China most types have CI3000 and Ci4000 and CI5000 model is basically a box in the majority.
Table type color fastness tester :
The desk is also called the desk type, convenient type and simple type. It is a kind of equipment that can be put on the table for aging test. The table adopts a air - cooled lamp tube or water - cooled lamp tube on the top of the inner bladder. Because of its simple structure and convenient use, it is widely used in many research institutes and colleges
