Photoelectric automatic particle counting instrument is a kind of seed counting instrument. Its working principle is: dropping countless seeds into electromagnetic vibrating feeders, this instrument has two feeders, according to the seed particles. Size to choose to use, turn on the power. When the electromagnetic vibrating screw feeder is started, the seed moves along the spiral turn and finally falls through the seed-feeding mouth into the next kind of channel (light guide) of the photoelectric system and falls into the splice container. In the process of falling, each seed produces a projection on the light pipe, so that the light pipe immediately assumes a high resistance, and then an electric pulse is formed on the photoelectric counting circuit, which is amplified and reshaped to trigger the counting circuit. Automatically counts seed counts. When the number reaches a predetermined number, the automatic control circuit operates to cut off the power supply of the electromagnetic vibrating feeder, stops the seed feeding, and emits a corresponding instruction signal chirping sound. This completes an automatic grain counting operation and displays the seed. Number of grains. When the number of samples is less than the predetermined number of particles, the number of samples and the predetermined number are displayed on the display.
In the seed sample project, there is still one more used together, that is, the seed germination box. The seed germinating amount is partly due to the genetic problem of the seed, and the other part is the external environment, and the seed germination box is One can create a suitable environment for seed germination.
Wooden Texture Series PETG Film
Wooden texture PETG Film is a material used for surface decoration of furniture. It uses PETG as the substrate, and uses printing technology to print wood texture patterns onto the surface of the film. Then, the film is applied to the surface of the furniture by hot pressing or pasting to achieve the effect of simulating wood grain.
Wooden texture PETG film has the following characteristics:
1. High simulation: Wooden texture PETG film can accurately reproduce various wooden texture patterns through high-definition printing technology, making the surface of the furniture look like real wood, giving people a natural and comfortable feeling.
2. Strong durability: The surface of the wooden texture PETG film is treated with a special process, which has characteristics such as wear resistance, scratch resistance, and pollution resistance, effectively protecting the surface of the furniture from damage caused by daily use.
3. Easy to clean: The surface of the wooden texture PETG film is smooth and flat, and it is not easy to absorb dust and dirt. It is very convenient to use, just wipe it with a damp cloth.
4. Cost saving: Compared to wood furniture, wooden texture PETG film is more cost-effective, which can effectively reduce furniture manufacturing costs. At the same time, it can also provide various wood texture options to meet the personalized needs of consumers.
Overall, wooden texture PETG film is a furniture decoration material with simulated appearance, strong durability, easy cleaning, simple installation, and economic benefits, which is increasingly favored by consumers.
