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...

Air-cooled Xenon Lamp Aging Tester

  The air-cooled xenon lamp aging tester is a device that uses an air-cooled system to dissipate heat and a xenon lamp to simulate ultraviolet light, visible light and infrared light in natural sunlight to perform accelerated aging tests on materials. It is commonly used in industries such as automobiles, coatings, plastics, rubber, and textiles. It can evaluate the aging resistance of materials under the combined effects of long-term light, temperature, humidity and other environmental factors in a relatively short period of time, helping companies improve product quality, extend service life, and optimize product anti-aging formulas and processes. Structural composition:  The main body is a test chamber, equipped with a xenon lamp and a matching optical filter system to simulate sunlight of different wavelengths, as well as temperature, humidity, lighting time and other control and adjustment devices, as well as an observation window and a sample rack. Working principle: The...

The Structure of Hexapod Tumble Tester

The Hexapod Tumbler Tester is a popular apparatus used in the evaluation of the appearance retention of carpets. Drum – constructed of Nylon or other like material and capped by a lid that is secured by a latching device. The drum and lid have a locating groove to hold the specimen backing sheet flat to the inner wall of the drum. A photograph of a typical drum is show in Photograph 1 and Photograph 2. The drum dimensions are:   Internal Diameter: 12 ± 0.18 in. (302 ± 5mm) Wall Thickness :0.3 in. approx. (8 mm approx.) Internal Depth: 8.2 ± 0.2 in. (207 ± 5 mm)  Driving System - cradles the drum on rollers and keeps the axis of the drum level, and rotates the drum at 35 ± 2 rpm (3.6 ± 0.2 rad/s). The driving direction reverses after approximately 500 revolutions.  After the 500 rotations the unit will stop and stand stationary for approximately 5 to 15 seconds, then begin rotating in the opposite direction. After 2000 rotations the unit will stop and w...
