When light travels to the interface between two media, if the degree of unsmoothness of the interface at the point of incidence is much smaller than the wave length, it can be regarded as a smooth interface. At this time, a part of the light will return to the original medium. This phenomenon is the reflection of light, which is also the principle of the reflection of light and shadow. The reflection of light on a smooth interface is called mirror reflection (or single-directional reflection). The reflected light, the incident light, and the normal are in the same plane. The reflected light and the incident light are on both sides of the normal, and the reflection angle is equal to the incident angle. If the interface is not smooth enough to be larger than the wave length, it will produce diffuse reflection. If there is both mirror reflection and diffuse reflection, it is called mixed reflection. If the brightness of light in different directions is the same in diffuse reflection, it is called uniform diffuse reflection. In the same reflection process, some of the light of some frequencies are reflected more, which is called selective reflection. It can use coating technology to change the optical properties of the interface of the medium, so that the reflected light can reduce or increase the light component of a certain frequency to adapt to the requirements of different optical components.

The Three Basic Meanings of Righteousness

The first basic meaning of being upright was to straighten one's heart. Just like straightening a crooked sapling, he had to make his inner thoughts and attitude move in a positive and positive direction. The second basic meaning was to keep one's heart pure. Not being polluted by those evil thoughts was like a clear lake that could not be muddy by dirty things. The third basic meaning was to calm one's heart. The heart was like a mirror. When it was calm, it could clearly reflect the things in the outside world. It would not be magnificent just because of a little wind and grass. Only by being calm could one deal with all kinds of things better. While waiting for the TV series, you can also click on the link below to read the classic original work of "Dafeng Nightwatchman"!

Fully Automatic PVP Granulator

The automatic PVP pellet machine is mainly used to process waste plastic (such as waste plastic film, including industrial packaging film, agricultural mulch film, greenhouse film, beer bag, handbag, etc., woven bag, agricultural convenient bag, basin, barrel, beverage bottle, furniture, daily necessities, etc.). It is a widely used and popular plastic processing machine in the waste plastic recycling industry. The principle was as follows: After the waste was thrown into the machine cylinder, it was cut into pieces by the high-speed rotating moving knife and the fixed knife. The chopped materials rotated along the inner wall of the cylinder under the effect of centrifugal force, and at the same time, they were turned up and down by the effect of the leaf pulp, moving from the periphery of the cylinder to the center. During the high-speed rotation, the friction between the materials, the cylinder, and the blade produced a large amount of friction heat, which caused the materials to rapidly heat up to a semi-plastic state and adhere to each other into small pieces. When the material is about to be agglomerated, a certain amount of cold water is sprayed into the cylinder. The cold water will evaporate and take away the heat when it meets the hot material. The unagglomerated material is broken into irregular particles by the action of the moving knife and the fixed knife, and then discharged through the discharge port to complete the pellet. In the process of pellet, it can also be added with paint to color according to the needs. The finished pellets can be directly used by the excavator and the injection machine. The following precautions for the automatic PVP pellet machine are as follows: the main motor and the oil pump motor are interlocked. If the oil pump motor is not started, the main motor cannot be started. If the main motor is not stopped, the oil pump motor cannot be stopped. The main motor and the feeding motor are interlocked. If the main motor is not started, the feeding motor cannot be started. If the feeding motor is not stopped, the main motor cannot be stopped. The main motor control cabinet is equipped with over-current protection and mechanical protection devices such as the safety coupling-type nylon-type shear-pin. When the designed moment is exceeded, the shear-pin will be cut off, and the transmission box will stop working. When the pressure of the machine head exceeds the set alarm value, the material pressure alarm signal light will light up and the machine will stop automatically. It is strictly forbidden to bring in metal sundries into the production raw materials. When the machine is running, it is strictly forbidden to use metal objects to clean the materials at the opening of the cylinder. When assembling and disassembling the pressure sensor and the material temperature thermocouples, if there is material in the machine head, it needs to be heated up and softened. It is recommended to use softened water or distilled water for the circulating water of the cylinder cooling system. The screw can only be started at a low speed (<20r/min), and the idling time should not exceed 2 minutes. After feeding, the screw can only gradually increase the speed when the material is discharged from the die hole of the machine head. The brands of the equipment were Zhongmei Tongda, etc. Different equipment had different parameters in terms of production capacity, number of rotating knives, number of fixed knives, swirl diameter, feed port diameter, filter plate aperture, cutter speed, machine center height, motor power, heating power, screw length, screw diameter, external size, weight, pot volume, etc. For example, the production capacity of the fully automatic PVP crystallizer of the Zhongmei Tongda brand was 100 - 150kg/h, with 6 rotating knives and 4 fixed knives. In terms of price, for example, Zhongmei Tongda's equipment ranged from 53,000 to 59,800 yuan. There were many equipment models and the related processes were complicated. It was necessary to determine the type selection after understanding the specific production needs. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!
