Cosmetics oxygen hose resistance performance test method of overview

Cosmetics oxygen hose resistance performance test method of overview on December 31, 2014 and in 2015 promulgated on March 2, the implementation of the standard of GB/T 31354 - 2014 'packaging and container oxygen permeability test method' is introduced with the coulomb sensor of measuring oxygen transmission rate that is dry packing standard test method. The following is a brief introduction: first of all, will be under test tube body mounted on the test fixture with sealant. After a period of time, seal samples are fixed on the test equipment. Pipe air slowly by nitrogen flow, pipe outside surface in the oxygen concentration known environment, namely the oxygen content is 20. 8% of the indoor environment with 100% oxygen or environment. Oxygen into the nitrogen carrier gas, nitrogen carrier gas was carried to the coulomb electricity sensor. By oxygen sensor will generate an electric current, electric current and per unit time to carry to charge sensor is directly proportional to the amount of oxygen. As a result, be able to get the whole tube of the oxygen transfer rate, better determine the shelf life of the product. Direct contact with human skin cosmetics, its quality will directly affect human body health. In order to guarantee product quality, service life and product life, the permeability test of rubber plate and pipe forming is very important. The standards 'GB/T 29336 - 2012 cosmetics use extrusion multilayer composite hoses 'clear rules of oxygen transfer hoses shall, in accordance with the provisions of this test test method (GB/t1038 plastic membrane permeability and table, and the layers of oxygen transfer line shall not exceed 10 / cm3 ( m2•24h•0. 1MPa) 。 Above is cosmetics oxygen hose resistance performance test method, it plays a very important role in cosmetics packaging, also is the main reason that cosmetics hoses are superior performance.
