What Is a Chemical Mixer?

The word means that the tool that mixes two different items together is called a mixer.

There are many kinds of mixers, and each customization is different, but the word means that the tool that mixes two different items together is called a mixer.

There are many types of mixers, which can be roughly divided into three types: TV signal mixers, ps channel mixers, and industrial mixers.

Among them, the TV signal mixer is also called a radio frequency signal mixer, an RF mixer, etc., and a signal mixer.

Industrial mixers are divided into pipeline mixers, soda mixers, vortex mixers, gas-liquid mixers, and static mixers.

Mixer channel mixer

The channel mixer is a command for color adjustment in Adobe photoshop software. This command can adjust the color component in a certain channel. Execute the "Image-> Adjustment-> Channel Mixer ^[1] " command to pop up the "Channel Mixer" dialog box. Output channel: You can select the channel in which you want to mix one or more source channels. Source channel: drag Blocking can reduce or increase the percentage of the source channel in the output channel, or directly in the text box. Enter a value between -200 and +200. Constant: This option can add an opaque channel to the output channel. If the value is negative, it is regarded as black channel, and the value is regarded as positive. Monochrome: Check this option to apply the same settings to all output channels to create a grayscale image in this color mode.

1) Working principle of channel mixer

A certain channel in the image is selected as a processing object (that is, an output channel), and then addition and subtraction calculations can be performed according to the channel information of the image and other channel information to achieve the purpose of adjusting the image. Note that the color information for addition or subtraction comes from the same image position of this channel or other channels. That is, the image color information of a channel in space can be calculated from the color information of this channel and other channels. The output channel can be any channel of the source image. The source channel is different according to the color mode of the image. When the color mode is RGB, the source channel is R, G, and B. When the color mode is CMYK, the source channel is C, M, Y, K. The channel mixer works only when the image color mode is RGB or CMYK. It cannot be operated when the image color mode is LAB or other modes.

2) Channel mixer operation

a) Open "Image"-"Adjustment"-"Channel Mixer".

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

c) Drag the slider of any source channel to the left to reduce the percentage of the channel in the output channel, or to the right to increase this percentage, or enter a value between -200% and +200 in the text box Value between%.

d) Drag the slider to enter a value for the Constant option. This option adds a channel with different opacity to the output channel.

e) If you want to get a grayscale image, select Monochrome to apply the same settings to all output channels to create a color image that contains only gray values. In the image to be converted to grayscale, the ratio of each source channel? To grayscale can be adjusted separately. If you select and deselect the Monochrome option, you can modify the mix of each channel individually to create a special-tone image.

f) Click OK to complete the operation.

Mixer static mixer

Since the 1970s, static mixers have been used in the chemical industry, food industry, textile light industry and other industries, and have achieved good results.

However, as a patented product, the static mixer ^[2] , both at home and abroad, not only keeps the structure secret, but also makes a one-time non-removable structure. At the same time, the viscosity of the curing agent and the epoxy resin are very different (the viscosity of the epoxy resin is 20 to 80 times the viscosity of the curing agent), and the flow velocity of the two fluids in the pipeline is very low, making them difficult to mix uniformly. Static mixer is an advanced unit equipment. Unlike agitator, it has no moving parts inside. It mainly uses fluid flow and internal unit to achieve a full mix of various flows and a reasonable design of a special structure. Compared with other equipment such as orifice plates, venturi tubes, agitators, homogenizers, static mixers have high efficiency, low energy consumption, small size, low investment, and easy continuous production. In a static mixer, the movement of the fluid follows the rule of "splitting-shifting-overlap", and the main role in the mixing process is shifting. The displacement methods can be divided into two categories: "relative displacement caused by the same cross-section flow velocity distribution and" multi-channel relative displacement ". Different types of mixers also have different displacement methods. HICHINE static mixer not only It is used in the mixing process, and can be used in processes related to mixing and 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, pharmaceutical, mining and metallurgy, food, daily chemical, pesticide, cable, petroleum, papermaking, chemical fiber, biological, environmental protection and other industries. Due to the low energy consumption of this product, the investment is low, the effect is good, and the effect is fast, it is for users Bringing considerable economic benefits. Static mixer is an advanced mixer that began to develop in the early 1970s. In 1970, Kenneth Company of the United States first introduced its research and development of static mixers. After the 1980s, domestic related enterprises also They have been put into research and production, and they have been well applied in the production of emulsified fuel.

1) Working principle of static mixer

The working principle of the static mixer is to make the fluid flow in the pipeline to impact various types of plate elements, increase the velocity gradient of the laminar flow of the fluid or form turbulence. When laminar flow is "segmentation-position movement-rejoining", In addition to the above three cases, the fluid will also generate a violent vortex in the direction of the section. A strong shear force acts on the fluid, which further divides and mixes the fluid, and finally mixes to form the required emulsion. The reason why it is called a "static" mixer is that there are no moving parts in the pipeline, only static components.

The mixing process of the static mixer is performed by a series of mixing units of different specifications installed in a hollow pipe. Due to the function of the mixing unit, the fluid rotates from left to right and from right to right, constantly changing the direction of the flow mixer, not only pushing the central fluid to the periphery, but also pushing the surrounding fluid to the center, resulting in a good radial mixing effect. At the same time, the rotation of the fluid itself will also occur at the interface where the adjacent components are connected. This perfect radial circulation mixing effect makes the material obtain a uniform mixing purpose. Static mixer is a kind of high-efficiency mixing equipment without movement. Through the internal components of the mixing unit fixed in the tube, the two or more strands of fluid can be cut, sheared, rotated and re-mixed to achieve good dispersion and sufficient fluid between the dehumidifier fluids. Purpose of mixing.

SV type mixer

The SV unit is a cylinder assembled from a certain size of corrugated plates with a maximum dispersion of 1-2 mm. The liquid and gas phases are suitable for liquid-liquid, liquid-gas, gas-gas with a viscosity of 102 centipoise. Mixed emulsification, reaction, absorption, extraction, and enhanced heat transfer processes.

It is suitable for unit operations such as chemical industry, petroleum, grease and other industries with a viscosity of 106 centipoise or mixing with polymer media with Korean training, heat transfer, mixing and heat transfer reaction, heating or cooling viscous products. The combined structure of high-shear dispersing emulsifier, high-speed disperser and special anchor mixer, therefore, its fluid model has changed greatly. When the high-shear dispersing emulsifier continuously sucks upward from the bottom of the tank and sprays it horizontally, it encounters the vertical cutting of the anchor agitator along the circumferential rotating flow at different height sections, so that the speed of the horizontal flow mold is registered. Trademarks were greatly weakened and distorted. The high-speed disperser further disperses and pulverizes the particles in the stream. Therefore, the multifunctional mixer strengthens the functions of emulsification, dispersion, homogenization, mixing and pulverization, and its performance is more superior. This machine is a multi-functional and efficient device that integrates dispersion and mixing. It is suitable for polymer lithium ion battery liquid and liquid lithium ion battery liquid, electronic electrode slurry, adhesive, mold glue, silicone sealant for studying in France The mixed mechanical seal of solid and liquid materials and the soft seal between the unique kettle body enable the materials to be operated under vacuum. The kettle body can be heated by electricity, steam and oil-water circulation. The unique temperature detection device on the kettle body ensures that the temperature is error-free, and the inner coil of the jacket can be cooled. The inner wall of the kettle is processed by a large vertical lathe to ensure that the materials on the inner wall of the kettle and the bottom of the kettle are completely scraped off when the movable scraper rotates. The other two sets of high-speed dispersers in the kettle subject various materials to strong shear and dispersion mixing.
