Apparatus and method for determining high temperature wettability

Abstract

The invention discloses an apparatus and a method for determining high temperature wettability. The apparatus comprises a heater body, a heating portion, an extruding dripping portion, a sample supporting portion and an image acquisition and processing portion. The heater body is comprised of a stainless steel cavity, a furnace lid and a No. 3 fluorine rubber ring bolt connecting together. A shielding layer in the heating portion is arranged in the center of a furnace bottom in the heater body, and a heating member is placed at the center of the shielding layer. The extruding dripping portionis perpendicularly arranged on an upper end of the heater body, and a lower end of a thermocouple in the heating portion, a lower end of the extruding dripping portion and an upper end of a sample bench are placed in the heater body. A substrate is placed at top of the sample bench. Two sets of CCD digital cameras or CMOS high speed cameras in the image acquisition and processing portion and a light source are respectively placed at the front and rear and the left and right of the heater body, and are in a same horizontal line with a symmetric axis of a quartz glass observation window, a wallthrough hole on the shielding layer and a heating member through hole on the heating member. The invention also provides a method for determining high temperature wettability.

AI Technical Summary

Benefits of technology

In this new technology, there's an improved way to measure how well molten aluminum (Al) falls into liquid when poured onto another material like steel). By separating the hot spot caused by melting off some parts of the copper plate called iron spots, we get ridges along its edges where impurities may come out. To prevent such issues, the current methods involve removing any unwanted substances before adding them to the mixture. Additionally, the use of specific techniques helps create clear images without distortion due to uneven distribution of atoms near certain points within the atom cloud. These technical improvements make measurements more accurate than previous methods while also improving efficiency compared to older methods.

Problems solved by technology

This patented technical problem addressed in this patents relates to real time measurements of liquid crystal compound (LC) surfaces with different properties like hydrophilicity/wettabilities at various temperatures. Existing techniques have limitations due to factors like oxidization caused by oxygen from air exposure and impurity levels within the LSZ layer itself.
