The application of vacuum pumps in white appliances is mainly divided into two categories: home appliance terminals and home appliance equipment. 一、The home appliance terminals are mainly Haier, Midea’s home appliance factories, which generally use rotary vane pumps and Roots pumps. 1.The...

UHV is the vacuum regime characterised by pressures lower than about 10−9 mbar (10-7 Pa). Ultra-high vacuum conditions are necessary to reduce surface contamination in many surface analytic techniques. For example X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), secondar...

With the rapid development of steelmaking technology, vacuum degassing technology has become an effective measure to reduce gas and non-metallic impurities in steel. The key lies in how to obtain vacuum. This article takes the vacuum treatment of molten steel outside the furnace using a liquid ri...

Application overview of various vacuum process technologies under different vacuum conditions As the density of gas molecules in the gaseous space decreases, the physical properties of the gas change significantly. Based on this change in gas properties, people use various vacuum processes under ...

The transfer printing technology is an emerging technology. It refers to the use of transfer paper as a transfer carrier for printing, and the use of vacuum to create negative pressure, so that the transfer paper and the transfer product are fully in contact and bear a certain pressure, and the t...
