In recent years, with the continuous development of the instrumentation industry, industrial instrumentation has not only become more functional, but also has greatly improved the reliability and longevity of instrumentation. Nowadays, there are three highlights in the development of industrial instrumentation. Which are the three highlights? First, the integration of system functions: With computer, power electronics and strong electrical control more closely combined, continuous control and intermittent control and use.
Second, the emergence of a new fieldbus architecture: expansion of the instrument's self-diagnosis function, and easy maintenance, the system connection is more reliable, easier, so the installation costs are greatly reduced, and the control scale is variable.
Third, the addition of new smart modules: new types of sensors such as fiber optic sensors, polymer sensors and biosensors will continue to emerge and will achieve rapid development.
Among them, the transmitter uses high-performance microprocessors and communications technology to achieve digital, communications, intelligent, improve the accuracy and range ratio, with temperature and pressure compensation, to achieve self-diagnosis, remote configuration, remote control adjustment zero , measurement range and PID control set point, and the use of dot matrix light column display technology, display measured variables and set values.
The detection instrument will continue to adopt new sensing technology and microelectronics technology, and it will be digitalized, intelligent, highly accurate, resistant to special media, special environments, capable of measuring limit parameters, non-contact measurement, and long-life direction. With the development of intermittent process control, on-line testing of various new types of instrumentation such as mechanical quantities, state quantities, and chemical composition will have new developments.
AEO are typical of non-ionic surface active agent, oxygen molecules of base mesh can be adjusted in the process of synthesis of human, it can be made of different properties and uses of non-ionic surface active agent, ether bond in the molecular is not easily destroyed by ACID, alkali, high stability, and it owns better water soluble, electrolyte resistance, easily biodegradable, small bubble, it is widely used in textile printing, dyeing industry and washing industry.
1.The series of products are acid-resisting and alkali-resisting, which is not sensitive to hard water. Cold washing performance is good. It also can be used to produce industrial cleaning agent.
2. In the textile dyeing and printing industry, because of its good scouring, diffusivity, levelness, wetability and foaming properties, it can be used as all kinds of dyes leveling agent, dispersant, peel color agent, retarding agent, printing reserving agent, prevent white agent and brightening agent.
3. In the chemical industry, it can be used to produce glass fiber emulsifier, chemical fiber spinning oil components, and improve spinnability of chemical fiber.
4. Used as a cleaner in the metal machining processes, it makes much easier to remove surface oil pollution, thus the follow-up process will be convenient.
5. In the latex industry, used as polymer emulsifiers in emulsion polymerization industry.
6. In the pesticide industry, it is used as fruit tree pesticide penetrating agent, emulsifier.
