When it comes to knowing and evaluating the surface strength of paper and paper boards, manufacturers make use of paper testing waxes. While these waxes are also used to determine the performance of the printing press. Typically, paper manufacturers, coated paper manufacturers, lithographers, printers, coating/printing paper inspection teams, etc. make use of these testing waxes.
UEC is a leading manufacturer and supplier of these waxes. Let us know about these waxes and how are they used by manufacturers and departments.
UEC Paper Testing Wax Sticks
UEC’s paper testing wax sticks are designed to determine the surface strength of the paper or to find out its resistance to picking. The paper could be both coated and uncoated paper and paperboard. Papers such as blotting papers, roofing felts, or those coated papers that contain thermoplastic resins in their coating adhesives could not be tested using these waxes.
- These hard resin wax sticks are made with non-oily waxes having high-grade adhesion.
- Each set has a set of 8 wax sticks of 18 x 18 mm, identified by an alphanumerical code.
- The wax sticks come with this numerical designation - 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A, 11A, 12A, 13A, 14A, 16A, 18A,2 0A, 23A.
How to Use Paper Testing Waxes?
Now that we have learned about paper and board testing waxes, let us now look at how these waxes are used to test the surface strength of paper. Manufacturers, printers, lithographers, etc. follow these steps to use paper testing wax sticks and evaluate the surface strength of paper and board.
- The operator heats the wax and applies it on the surface of the paper specimen.
- As the wax cools, the operator pulls it from the surface of the specimen. The pulled wax determines if it has pulled the fiber of the surface coating.
- The operator determines the highest-value wax that does not rupture the surface of the paper. This is concluded as the picking strength of the paper.
UEC not only manufactures and supplies paper and board testing waxes, but also other surface testing and printability testers. A wire bar coater is among the most sought instruments among paper manufacturers and printers. Know about the entire range of instruments on the website.
