Test Procedure of Fabric Thickness Gauge

Qinun Fabric Thickness Gauge has a complete assortment of the presser-foot and weights to conform to different test-methods. The textile samples shall be conditioned and the test conducted in the standard atmosphere for conditioning and testing of textiles specified in ISO 139. The test procedure is shown as below:


Clean the presser-foot and the reference plate. Check that the presser-foot shft moves freely. Load the presser-foot to exert the appropriate specified pressure on the reference plate, and set the thickness gauge to read zero. An applied pressure of (1±0.01)kPa is recommended.

Raise the presser-foot and position the sample or test specimen, without tension and distortion, on the reference plate so that no part of the area to be measured is closer than 150mm to the selvedge. Ensure that the area chosen for the test is free from crease.

Lower the presser-foot gently onto the specimen and note the gauge reading after (30±5)s.

Determine, in accordance with the procedure above, the thickness of at least five different areas on the sample or at least five test specimens.

Calculate the arithmetic mean of the measurements to an accuracy of 0.01mm. Calculate the coefficient of variation to the nearest 0.1% and the 95% confidence limits to the nearest 0.01mm.

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...
