Membrane machine is currently the most widely used equipment for making vacuum conditions. Its related components and components: mechanical pump, booster pump, oil diffusion pump, condensate pump, vacuum measurement system.Vacuum body-Vacuum chambers have different requirements according to the processed products, and the size of the vacuum chamber is also different. At present, the most widely used are 1.3M, 0.9M, 1.5M, 1.8M, etc. The chamber is made of stainless steel, and the requirements Ru... read more
In general, metal targets show high reflectivity and silvery white in the range of visible light (380-780nm), but some non-ferrous metals, such as gold and copper, have selective absorption in a specific wavelength range, so special colors appear. In the light near 470nm, the selective absorption of gold is due to the electron transition, so it shows a unique golden yellow color. In the actual coating, I often use the method of target plus gas to form metal compounds to debug various colors. The... read more
The range of visible light is about 400-800 nm. If the light with the wavelength of 400-800nm is mixed evenly according to the appropriate proportion, and then it hits the retina of the eye, it will produce a white light sense. But why does matter show different colors? The first to reveal the secret of color is English scientist Newton. He used a prism to refract the sunlight twice. For the first time, he successfully decomposed it into seven color bands: red, orange, yellow, green, blue, blue ... read more
We are not unfamiliar with light, because we live in the world of light every day. All kinds of non luminous objects have bright colors. Only when enough light is shining, can we see them for people. All luminous objects can become light sources, while the sun is a huge natural light source and the only light source in the day for human beings. In fact, daylight light source is a natural light composed of direct light and reflected light in the sky, also known as overcast light.Automotive car li... read more
When we see an object, we first feel its color. The color of matter is visible to the human eye. If there is no light in the closed darkroom, or in the dark night, the color of the object is invisible. Only in light, the color of matter can be seen by the naked eye, so we say that color is produced by the interaction of light and eyes. In fact, color is the result of the brain's recognition of different kinds of light projected on the retina.Chrome Metallization Coating Machine Suppliers ... read more
