With the rapid development of modern science and technology informatization, consumers have higher and higher requirements for industrial products, which promotes the widespread use of ultraviolet weathering testers in modern industrial enterprises. The ultraviolet weather resistance testing machine is to simulate the ultraviolet radiation and condensation in the sunlight of nature, and accelerate the weather resistance test of the material to obtain the result of the weather resistance of the material. By reproducing environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, darkness, etc., they are combined into one cycle, and it is automatically executed to complete the number of cycles. The equipment conducts the test by exposing the material to be tested in a controlled alternating cycle of sunlight and moisture while increasing the temperature. The equipment uses ultraviolet fluorescent lamps to simulate sunlight, and can also simulate the effect of moisture through condensation or spraying.
The ultraviolet fluorescent test tube is a kind of low-pressure mercury lamp. It is a sterilization lamp that emits ultraviolet light after being excited by low-pressure mercury vapor (<10-2Pa). It is made of pure quartz glass made of natural crystal. The UV penetration rate of pure quartz tube is very high, usually can reach 80% -90%. However, the penetration of ultraviolet lamps is not absolutely unaffected by external factors. In fact, some factors such as paper, lead glass, plastic, etc. will relatively reduce the irradiation intensity. Then, the dust and grease on the outer wall of the lamp tube will directly affect its penetration ability. In this regard, we should pay attention to the cleanliness and maintenance of the lamp tube during the use of the ultraviolet weather resistance testing machine. Before the new UV lamp is used, it can be wiped with a 75% alcohol cotton ball, and it is generally appropriate to wipe it every 2 weeks after it is put into use. If there is dust or oil on the surface of the lamp, it should be wiped clean at any time to keep the lamp clean and transparent, so as not to affect the penetration of ultraviolet light and the intensity of radiation.
Create perfection and serve customers. Beijing Yashilin belongs to Beijing, belongs to the Chinese nation, and belongs to the world society.
Wire backed silt fence (WBSF) is constructed with a three or four feet high wire scrim, covered with a woven poly propylene filter fabric. The galvanized steel scrim supports the fabric in an upright position even under substantial loads of silt and water. A fabric apron extending beyond the wire is also available.
