PS Channel Mixer is a command about color adjustment in Adobe photoshop software. This command can adjust the color components in a channel. Execute image->; Adjust->; The Channel Mixer command pops up the Channel Mixer dialog box. Output channel:: You can select the channel where you want to mix one or more source channels. Source Channel: Drag the slider to decrease or increase the percentage of the source channel in the output channel or directly in the text box. Please enter a value between -200 and +200. Constant: This option can add an opaque channel to the output channel. If it is negative, it is regarded as a black channel, and if it is positive, it is regarded as a black channel. Monochrome: Select this option to apply the same settings to all output channels, thus creating a grayscale image in this color mode.

Working principle of channel mixer

Select a channel in the image as the processing object (that is, the output channel), and then add and subtract according to the information of this channel and other channels of the image to achieve the purpose of adjusting the image. Note that the color information to be increased or decreased comes from the same image position of this channel or other channels. That is to say, the image color information of a certain channel in space can be calculated according to the color information of this channel and other channels. The output channel can be any channel of the source image, and the source channel will be different according to the color mode of the image. When the color mode is RGB, the source channels are R, G and B, and when the color mode is CMYK, the source channels are C, M, Y and K. Assuming that the cyan channel is the processing object, that is, the result of the operation in the figure is only reflected in the cyan channel, then the cyan channel is the output channel. The calculation in the figure is: the original color information of cyan channel of all images (the slider is still at 100%), minus 32% yellow information of the same image position, plus 22% magenta channel color information of the same image position, and then increase the dot size of 16%. So the percentage of cyan dots in the output image is: C=C+Mx22%-Yx32%+ 16%. For example, the color of an image is C40%M50%Y30%K0%, and the output is C57%M50%Y30%K0% after calculation and processing in the figure. The "constant" in the figure refers to the percentage that the information in this channel directly increases or decreases in the maximum color representation, where 10% is actually 10%× 100%. The channel mixer only works when the image color mode is RGB or CMYK, and cannot operate when the image color mode is LAB or other modes.

Channel mixer operation

1. Open the image adjustment channel mixer.

2. Select the output channel, that is, the channel you want to adjust.

3. Drag the slider of any source channel to the left to reduce its percentage in the output channel, or drag it to the right to increase the percentage, or enter a value between -200% and +200% in the text box.

4. Drag the slider to enter a value for the constant option. This option adds channels with different opacity to the output channel.

5. If you want to get a grayscale image, select Monochrome to apply the same settings to all output channels to create a color image containing only grayscale values. In the image to be converted to grayscale, each source channel can be adjusted separately. Form a gray scale. If you select the monochrome option first and then deselect it, you can modify the mixture of each channel separately to create an image with a special hue.

6. Click OK to finish. Since 1970s, static mixers have been applied in chemical industry, food industry, textile industry and other industries, and achieved good results. However, as a patented product, the static mixer is not only kept secret at home and abroad, but also made into a disposable structure. At the same time, the viscosity of curing agent and epoxy resin is very different (the viscosity of epoxy resin is 20 ~ 80 times that of curing agent), and the flow velocity of the two fluids in the pipeline is very low, so it is difficult to mix them evenly. Static mixer is an advanced unit equipment. Different from the agitator, it has no moving parts inside, and mainly uses fluid flow and internal units to achieve complete mixing of various fluids and special design rationality. Compared with other equipment such as orifice tower, venturi tube, agitator and homogenizer, static mixer has the advantages of high efficiency, low energy consumption, small size, low investment and easy continuous production. In the static mixer, the movement of fluid follows the law of "diversion-displacement-overlap", and displacement plays a major role in the mixing process. Displacement modes can be divided into two categories: "relative displacement caused by velocity distribution in the same section" and "multi-channel relative displacement", and the displacement modes of different types of mixers are also different. The static mixer of Haitai Maxim can be used not only in the mixing process, but also in the processes related to mixing-transfer, including gas/gas mixing, liquid/liquid extraction, gas/liquid reaction, enhanced heat transfer and liquid/liquid reaction. Static mixers are widely used in plastics, chemical industry, medicine, mining and metallurgy, food, daily chemicals, pesticides, cables, petroleum, paper making, chemical fiber, biology, environmental protection and other industries. The product has the advantages of low energy consumption, low investment, good effect and quick response, which brings considerable economic benefits to users. Static mixer is an advanced mixer developed in the early 1970s. 1970, the static mixer developed by Kenis Company of the United States was first introduced. Since 1980s, domestic related enterprises have also invested in research and production, which has been well applied in the production of emulsified fuel. Working principle of static mixer

The working principle of static mixer is to let the fluid flow in the pipeline and impact various plate elements, thus increasing the velocity gradient of fluid laminar flow or forming turbulence. In laminar flow, it is "splitting-position shifting-rejoining". In turbulent flow, in addition to the above three situations, the fluid will also generate violent vortices in the cross-sectional direction, and strong shear force will act on the fluid, which will further split and mix the fluid and finally mix to form the required emulsion. The so-called "static" mixer means that there are no moving parts in the pipeline, only static elements.

The mixing process of static mixer is completed by a series of mixing units with different specifications installed in hollow tubes. Due to the function of the mixing unit, the fluid rotates from left to right, and the direction of the flow mixer changes constantly, which not only pushes the central fluid to the periphery, but also pushes the peripheral fluid to the center, thus producing good radial mixing effect. At the same time, the rotation of the fluid itself will also occur on the interface of adjacent components. This perfect radial circulation mixing effect makes the materials mix evenly. Static mixer is a kind of efficient mixing equipment without movement. Two or more fluids are sheared, rotated and remixed through the mixing unit fixed in the pipeline, so as to achieve the purpose of good dispersion and full mixing between dehumidifier fluids. SV-type unit is a cylinder assembled by corrugated plates with certain specifications, and the highest dispersion is 1-2mm. Liquid-liquid phase and gas-gas phase are suitable for mixed emulsification, reaction, absorption, extraction and enhanced heat transfer of liquid-liquid, liquid-gas and gas-gas with viscosity of 102 centipoise. The unit consists of a single-hole spiral piece twisted left and right, with the highest dispersion range of 10um, and the solid phase heterogeneity coefficient of liquid-liquid and liquid translation company. It is suitable for mixing, reaction, extraction, absorption, injection molding, color matching and heat transfer in chemical industry, petroleum, pharmacy, food, finishing, plastics, environmental protection, synthetic fiber, mining and other departments. It is suitable for high viscosity media with small flow mixed with impurities or viscosity of 106 centipoise. The unit consists of many X-shaped units crossing bars according to certain rules. Technical characteristics: the mixing unevenness is S, which is suitable for the liquid-liquid reaction, mixing and absorption process with medium and high viscosity of 104 centipoise, and the mixed reaction process of liver cancer or polymer produced liquid is better when the treatment capacity is large. The unit consists of two channels, in which spiral blades are placed, and there is a fluid redistribution chamber between adjacent units, and the orientation of the two channels is staggered by 90. The highest dispersion is 1-2mm, and the liquid-liquid unevenness is 1-5%. 0.6 centipoise high viscosity cleaning medium is especially suitable for mixing. This unit is a single X-shaped unit composed of crossed bars according to certain rules. Its technical characteristics are liquid-liquid and liquid-solid mixing, and the non-uniformity coefficient is 5%. It is suitable for chemical, petroleum, grease and other industries with viscosity of 106 centipoise or mixed with polymer media cultured in Korea, as well as unit operation of heat exchanger, heating or cooling viscous products, etc. Because of the combined structure of high shear dispersing emulsifier, high speed dispersing machine and special anchor mixer, its fluid model has changed greatly. The high-shear dispersion emulsifying machine continuously sucks upward from the bottom of the tank, and when spraying horizontally, it encounters vertical cutting of the circumferential rotating flow of the anchor agitator at different heights, which greatly weakens and distorts the registered trademark of the advection mode speed. The high-speed disperser further disperses and crushes the particles in the material flow. Therefore, the multifunctional mixer strengthens the functions of emulsification, dispersion, homogenization, mixing and crushing, and its performance is more superior. This machine is a multifunctional and efficient equipment integrating dispersion and mixing. It is suitable for the mixed mechanical seal of polymer lithium-ion battery liquid, liquid lithium-ion battery liquid, electronic electrode paste, adhesive, molding compound and silicone sealants, and the unique soft seal between kettle bodies, so that the materials can run under vacuum. The kettle body can be heated by electric heating, steam heating and oil-water circulation heating. The unique temperature detection device on the kettle body ensures that the temperature is error-free, and the coil in the jacket can be cooled. The inner wall of the kettle is finished by a large vertical lathe to ensure that the movable scraper can completely scrape the materials on the inner wall and bottom of the kettle when rotating. There are two other groups of high-speed dispersers in the kettle, which make all kinds of materials subject to strong shearing and dispersion and mixing.
