Heat distribution measurement film (Thermoscale)
THERMOSCALE is a revolutionary new film that enables anyone to measure heat distribution easily by observing the variation on density and hue.
Structure
The base film is coated with a thermosensitive colour-forming layer and a protective layer. This is the non-glossy surface that comes into direct contact with the heat source. The glossy side of the sheet is used to observe the colour patterns that represent heat distribution.
How it works
Heat melts the developer and makes the microcapsule walls permeable, allowing developer to enter the microcapsules, where it reacts with the colour-forming agent to produce colour.
Cut a piece of THERMOSCALE film to the required shape/length and place it on or inside the equipment with the non-glossy side facing the heat source.
Operate the equipment in the normal manner to bring the THERMOSCALE sheet in direct contact with the heat source.
Colour patterning is produced on the THERMOSCALE sheet
Remove the THERMOSCALE sheet and observe from the glossy side. The colour patterning indicated the heat distribution over the heating surface.
Features
The extent of colour change depends on the temperature of the heat source and the contact time. A shorter contact time produces paler colours with a blue tint. As the contact time increases (at the same temperature), the colours become deeper and take on a red tint. Note that the colour change is also influenced by factors such as the type of material on the opposite side (i.e., the non heat source side), thermal characteristics, contact pressure and air flow (see below).
Uses
THERMOSCALE uses special technology that regulates colour intensity and hue in accordance with heat value to generate a highly accurate depiction of heat values over a wide range. THERMOSCALE is ideal for applications involving analysis of heat distribution during press, roll, and laminate processes and within drying ovens.
Printed substrates, solar panels, protective film laminating.
ACF compression bonding, heat seals, Li-ion batteries, solar panels.
Nip roll, calendar roll, printing roll, printer roll.
Drying oven, baking oven, vacuum film production, measuring surface heat distribution on parts.
