Both the air-cooled xenon lamp aging test chamber and the water-cooled xenon lamp aging test chamber can simulate the effect of outdoor damp by spraying water on the test sample. This method is particularly effective for simulating thermal shock or mechanical corrosion.
In the air-cooled xenon lamp aging test chamber, the test sample was mounted on a flat sample tray and tilted horizontally by 5 °C. The spray water can be evenly sprayed onto the surface of the sample, and as the sample is placed close to the level, the water does not flow away, leaving the sample moist throughout the wet cycle.
The water-cooled xenon lamp aging test chamber has a spray bar and a nozzle that sprays water as it passes. The sample is wet for about 3 seconds per minute. Some xenon lamp aging test chambers are equipped with 2 spray strips that can be sprayed simultaneously on the front and back of the sample. As the sample is placed vertically, water will quickly flow away from the surface. In the wet gap, the sample may dry out after being turned away from the spray position.
Copper nuts made of all kinds of embossed wire (usually lead brass, such as H59, 3604, 3602). Our daily contact with the embedded knurled copper nuts are processed by precision automatic lathes. The reference standard of embedded knurled copper nut comes from GB/T809, but the technical parameters of all kinds of embedded nuts produced by our company exceed the relevant indexes required by the national standard.
Knurling copper nut is mainly used for hardware Spring, shaped spring, craft gift spring, battery spring, spring antenna,key ring, phosphorus copper spring CNC automatic lathe turning parts (copper car parts, iron, aluminum car parts), metal stamping parts, electronic parts, iron shaft, single Rachel,Rachel, iron pin, non-standard Screw nut,fittings,fasteners, wire forming (wire card holder, Model aircraft landing gear, S hook, R latch, triangle buckle, D buckle) and other hardware products, belonging to the copper nut series.
