At major exhibitions, we often see some very small and exquisite testing instruments, ranging from mass spectrometers to centrifuges, and their stature has gradually become smaller. This reveals the development direction of the analytical instrument industry in recent years: miniaturization. With the continuous development of micro-electro-mechanical technology and the continuous maturation of technology and the continuous reduction of prices, its application areas will continue to increase. Therefore, miniaturization is one of the development trends of future instrumentation. Micro-intelligent instruments refer to microelectronics, micro-mechanics, and information technology that are integrated into the production of the instrument, making the instrument a small, full-featured intelligent instrument. It can complete signal acquisition, linearization, digital signal processing, control signal output, amplification, interface with other instruments, and human interaction.
Micro-instruments will not only have the functions of traditional instruments and meters, but also play a unique role in the fields of automation technology, aerospace, military, biotechnology, and medical care. Analytical instruments will not only have more and more powerful "smart", but are also developing in the direction of large-scale floor-to-ceiling, desktop-mobile, portable, hand-held, and chip-based laboratories. They are becoming increasingly compact, miniaturized, and intelligent. , So that there is an implantable or embedded smart instrument that can wearable or even no external power supply.
From the perspective of instrumentation itself, micro-instrumentation is also a long-term goal pursued by people. To date, this goal has been partially achieved. For example, a portable micro-metal detector can easily detect water quality. The traditional mass spectrometer for elemental analysis is a large-scale device, which has many parts such as vacuum long-distance bending, and it has been done as small as a desktop computer. And has begun to develop in the direction of the handheld, and so on. With the development of science and technology, aerospace, medical equipment and other fields have special requirements on the size and quality of instrumentation, which has also led to further miniaturization and miniaturization of instrumentation.
With the continuous development of micro-electro-mechanical technology, micro-intelligent instruments, their technologies continue to mature, prices continue to decline, so their application areas will continue to expand. It not only has the functions of traditional instruments, but also can play a unique role in the fields of automation technology, aerospace, military, biotechnology, and medical care.
Screw and barrel are two essential components of plastic extrusion machines. They work together to melt and shape plastic materials into various forms. The screw is a rotating helical shaft that moves the plastic material through the barrel, which is a stationary tube. The screw and barrel are designed to work together to provide the right amount of heat, pressure, and shear to the plastic material. In this article, we will discuss the screw and barrel in detail and their importance in the plastic extrusion process.
The screw and barrel are essential components of plastic extrusion machines. They work together to provide the right amount of heat, pressure, and shear to the plastic material. The screw and barrel are designed to be precise and efficient, which results in high-quality plastic products.
The screw and barrel are also designed to be durable and long-lasting. They are made of high-quality materials that can withstand the high temperatures and pressures of the plastic extrusion process. The screw and barrel are also designed to be easy to clean and maintain, which reduces downtime and increases productivity.
