Overview
PUSHEN XB-I 25μm Mayer Rods is a laboratory bar that uses grooves formed by stainless steel wire winding to control wet film thickness. It can be prepared with a wet film thickness of 20 microns, a total length of 240mm, and an effective application width of 200mm. Widely used in plastics, inks and other industries, stainless steel has a long service life.
Features
1. It is very suitable for thin coatings of Spreader, such as can Coatings and paper Coatings.
2. For soft materials such as paper, Cardboard, foil, leather, test cardboard, Spinning & weaving products and other effects are most satisfactory.
3. The rods and wires are made of high-grade wear-resistant stainless steel.
4. Spreaders wet film thickness engraved at the end of XB bar.
Principle
The lab bar uses stainless steel wires to wrap around its surface to form grooves, and prepares films of different thicknesses through the gaps between the wires. Wire of different diameters is wrapped around a certain length of stainless steel steel bars, and the gaps between the wires are used to prepares films of different thicknesses.
Applications
Plastics, inks, paints, varnishes, inks, glues
Steps
1. According to the calculation formula of wet film thickness: wet film thickness = Coating Weight g/(density × Solid content%) per square meter for selection.
2. Use bar-wound stainless steel wire grooves to control Spreader thickness.
Notice
* The calculation formula of wet film thickness is for reference only. The actual wet film thickness is also affected by various factors such as product ductility, viscosity, and coating rod type.
Samples need to be uniform and comparable, with precise thickness control to ensure Test Reliability.
