Ink Abrasion Test Procedure

Ink abrasion tester simulates a similar environment to test the rub resistance on printed materials.It is used to analyze the life of label by creating actual environment of application to evaluate abrasion resistance of surface coating layer of printed material.inks rub resistance tester simulates the actual working environment of product and helps to identify the quality and printing method to be used for printing of label based on application of product and its working environment.

Ink abrasion test, also known as Ink Rub test, is to measure the ink resistance against rubbing on packaging materials, professionally designed for abrasion resistance of surface coating layers of printed materials, e.g. ink layer or photosensitive (PS) coating. This instrument could effectively analyze the problems of poor abrasion resistance, ink layer falling off, lower printable force and poor hardness of coating layers of printed materials.

The tests are performed according to the following procedures.
1.Cut one piece of specimen from the provided sample and then fix the specimen in the test plane of the instrument. The size of the specimen should be 230mmx50mm.
2.Use a reflection densitometer to measure the density of the ink layer on the surface of the specimen.
3.Fix the rubber pad on the test block and then place it onto the specimen.
4.Set rub times and then start tests. The rubber pad with test block will rub on the specimen surface until the preset rub times are completed.
5.When tests are finished, the density of ink layer will be measured by reflection densitometer and the abrasion resistance of the specimen will be calculated.

Tinuvin 1130: An Excellent UV Absorber

 In the field of the chemical industry, UV absorbers play a crucial role, particularly in protecting materials from UV damage. Today, we will delve into a highly regarded UV absorber—Tinuvin 1130. Tinuvin 1130 : chemical name: 3-(3-(2H-benzotriazole-2-yl)-4-hydroxy-5-tert-butyl phenyl)propionic acid polyethylene glycol 300 ester; CAS login number: 104810-48-2. This product is an exceptional UV absorber that offers numerous benefits due to its unique properties. One of the standout features of Tinuvin 1130 is its excellent weather resistance. It has a strong ability to absorb ultraviolet rays, particularly those with wavelengths ranging from 290-400nm. This effectively prevents coatings, plastics, rubber, and other materials from being damaged by UV rays, thereby maintaining the performance and appearance stability of these materials and extending their service life. In addition, Tinuvin 1130 exhibits good compatibility. It is easy to emulsify in water-based systems and can be...

Ink Abrasion Tester For Ink Layer Abrasion Test

        Abrasion resistance of ink layer is one important parameter that is used to evaluate the printing quality. If the abrasion resistance of the ink layer is poor, the printed words on the paper or paperboard may become illegible and the part with printed area may be abraded in transportation, storage or in use.                   As a result, the printed words will be not able to be read by the customers, which cause inconvenience or misunderstanding and thus the product image would be compromised. Therefore, it is necessary for the manufacturers to test the abrasion resistance of the ink layer on the paper or paperboard before use.         Often during the shipping or handling process, printed products will be exposed to a degree of abrasion to its surface. Regardless of quality or perfection of the printed product, a scuffed, rubbed off or scratched surface would render it a print defect...

Mechanism of action of benzonitrile

  Product identification： Product name:  Benzonitrile Molecular formula: C7H5N CAS No.100-47-0 Benzonitrile is a colorless oily liquid with an almond-like odor. It is slightly soluble in cold water, soluble in hot water, and easily soluble in organic solvents such as ethanol and ether. The mechanism of action of benzonitrile can be elaborated from the following aspects: I. Chemical Properties and Applications As an Intermediate in Organic Synthesis: Benzonitrile plays a crucial role in chemical synthesis as an intermediate for many important compounds and materials. For example, it can be used to synthesize advanced coatings such as phenyl melamine, as well as compounds such as pesticides, aliphatic amines, and benzoic acid. These compounds have a wide range of applications in agriculture, coatings, plastics, and other fields. As a Solvent: Benzonitrile possesses good solubilizing properties and can be used as a solvent. In organic synthesis, it is often used as a solvent to d...
