Temperature Control Soultion for Wafer Cleaning Solution in Semiconductor Industry
With the rapid development of semiconductor technology, the requirements for wafers are getting higher and higher, making clean wafer surfaces more and more important for the manufacturing of semiconductor devices. In the wafer manufacturing process, cleaning is required after each step of the process. At present, the wafer cleaning and etching methods often need to set up a large number of spraying structures to spray different chemical solutions to the wafer surface for cleaning and etching...

1. If the product quality is not affected by the presence of air at a higher temperature, it can be recovered at normal pressure first, and when the temperature exceeds the normal pressure boiling point of the desolvent by 10 degrees, when the solvent cannot be evaporated, change the receiving bottle, and then reduce Pressure, the degree of vacuum rises slowly from -0.01mpa to the maximum according to the flow rate. Continue to keep for 0.5 hours until no liquid flows out. 2. If the product ...

How to control the emulsification temperature of the emulsifier?
A good cream product is not only reflected in the quality of raw materials, but also has a great influence on the emulsification process during production, such as the texture and stability of the product, and the temperature control during production will affect the cream product. Generally speaking, the emulsification temperature is determined by factors such as the melting point of the high melting point substance contained in the two phases, the type of emulsifier, the solubility of the o...

에나멜 리액터를 사용하는 것이 왜 위험한가요?
The enamel layer of the enamel reaction kettle is easy to burst when it is cold and hot. Because the enamel layer is sintered on the surface of the enamel reaction kettle, and the enamel layer will melt when it exceeds 200 degrees Celsius, so the temperature of the material in the kettle is not allowed to exceed 200 degrees Celsius, so the enamel kettle has a temperature resistance limit of 200 degrees Celsius, and the temperature resistance rapidly becomes cold. Shock <110℃, thermal shoc...

차량 고온 및 고습 테스트 차량 노화 방지 성능 테스트
On test benches in the automotive industry, accurate temperature simulation is critical. From the time of the test, the air temperature in the test chamber has always been maintained at 45 ℃, which is equivalent to the hottest area of the Flaming Mountains in Turpan, Xinjiang, China. Ultra-high temperature environments cause all automotive components, from control electronics to gaskets and load-bearing elements, to experience severe temperature fluctuations that, in addition to mileage, str...
