Evaluating Surface Resistance To Picking With Paper Testing Waxes

by Universal Engineering Corporation Suppliers Of Precision Testing Instruments in Saha

When it comes to choosing paper coating testing equipment, paper testing waxes play a significant role. Designed specifically for paper manufacturers, printers, lithographers, etc. the paper testing waxes are ideal for determining the adhesive strength of the paper surface. Be it coated or uncoated paper, testing waxes can effectively test the resistance of the picking. Picking usually occurs when the paper surface blisters or lifts, and the paper or the coating adheres to the wax surface. These waxes could not be used for loosely felted papers including blotting papers or coated papers whose coating adhesive contains thermoplastic resins.

Once this is known, the level of sizing in the coating and the pressing needed can be determined. Let us read in the following section why surface coating is done and how coating testing equipment works.

Why Surface Coating Is Used?

Surface coating is done to boost the shelf life of the paper and minimizes its downtime maintenance cost. It is due to these significant reasons that manufacturers, lithographers, etc. use surface coating instruments. Let us understand the advantages of using these instruments in-depth below.

Requirements For Printing Operations

A number of printing operations need paper surfaces to possess the necessary transverse strength so that satisfactory results can be obtained. Since these waxes do not give an accurate or absolute value, the actual performance of the material can be known during the coating, printing, or packaging functions.

Increasing the Shelf Life Of The Paper

Surface coatings make paper and other products long-lasting and durable. The resulting longevity and productivity of the paper help in achieving the objective, for which it is being used.

Industries like medical, food, waffle-making companies, etc. use these surface coating machines to a great extent. UECIN’s wire bar coater is one such instrument that performs a uniform coating of paper.

Coated Paper With Resins

Thermoplastic resins replace a major portion of the starch coating adhesive in some coated papers. This results in a very less correlation between the performance of the printing press and the results of wax testing. The waxes actually create a strong bond with the coating that contains thermoplastic resins, making the paper stronger.

Reducing The Maintenance Cost

By using surface coatings, manufacturers can make the product resistant to chemicals, corrosion, electrical insulation, etc. This helps in minimizing the maintenance cost of the product, hence saving a lot of financial resources.

How do UECIN’s Paper Testing Waxes Help?

The set of paper testing waxes contains a range of 8 hard resin and nonsticky and non-oily wax sticks. These waxes have a high degree of adhesive qualities. Each wax stick comprises a cross-section of 18 mm by 18 mm and has a code number for identification. Manufacturers of paper or coated paper, lithographers, printers, and companies concerning development, examination, and controlling paper coating and printing use, employ these waxes.
