ã€China Aluminum Industry Network】Aluminum profiles need to be oxidized before they are painted. Extrusion of good aluminum alloy profiles has poor surface corrosion resistance and must be anodized for external disposal to add resistance to aluminum. Erosion, wear resistance and the appearance of beautiful.
Its main process is:
(1) Appearance pre-treatment: Chemical or physical methods are used to clean the appearance of the profile, exposing the pure matrix to facilitate obtaining a complete and fine artificial oxide film. It is also possible to obtain a specular or matt (matte) appearance by mechanical means.
(2) Anodic Oxidation: Under the certain technical conditions, the externally pre-treated profiles undergo anodic oxidation to form a fine, porous, strong AL203 film layer.
(3) Sealing: The pores of the porous oxide film formed after the anodization are closed, so that the oxide film can be prevented from contamination, corrosion and abrasion resistance. Oxide film is colorless and bright. The strong adsorption of the oxide film before sealing is used. Adsorption of some metal salts in the film pores can make the appearance of the profile besides flashing (silver white), such as: black, bronze, Gold and stainless steel and so on.
The
15 lights, 30 lights, and 60 lights refer to the number of LED components welded per meter length of the LED strip. Generally speaking, the 1210 specification strip has 60 LEDs per meter, and the 5050 specification strip has 30 LEDs per meter. Special There are 60 LEDs per meter. The price of LED strips with different LED quantities is different, which is also an important factor in distinguishing the price of LED strips.
Color temperature
It refers to heating a standard black body. When the temperature rises to a certain level, the color starts to change from dark red-light red-orange-white-blue. When the color of a certain light source is the same as that of the black body, we call the absolute temperature of the black body at that time Is the color temperature of the light source.
Generally speaking, color temperature is not used as an indicator for evaluating LED strips, but many foreign customers will make a special requirement due to the use environment.
The color temperature of the light source is different, and the light color is also different:
The color temperature is below 3300K, and the light color is reddish to give a warm feeling; it has a stable atmosphere and a warm feeling. It is commonly known as warm color temperature.
The color temperature is in the middle of 3000-6000K, and people have no obvious visual psychological effect under this color, and there is a refreshing feeling; therefore, it is called "neutral" color temperature
The color temperature exceeds 6000K, and the light color is bluish, giving people a cool feeling, commonly known as cool color temperature.
