Description

Chemical substance penetration testing device for rubber products Technical Field The invention relates to the technical field of rubber product penetration test equipment, in particular to a chemical substance penetration test device for rubber products. Background The rubber product is made of natural rubber or synthetic rubber as main raw material and has various properties and uses, and the rubber product has wide application in various fields such as industry, daily life and the like. For example, in the automotive industry, rubber seals, tires, and other parts are critical to the performance and safety of vehicles, and in the medical field, rubber gloves, catheters, and other articles come into direct contact with the human body. However, in the use process of the rubber product, various chemical substances possibly can be contacted with the rubber, and the chemical substances can permeate into the rubber, so that the performance and the service life of the rubber product are affected, even the damage to human health and the environment can be caused in some cases, the chemical substance permeation test device of the rubber product is mainly used for simulating the contact scene of the rubber product with various chemical substances in the actual use process, and parameters such as the permeation rate, the permeation depth, the permeation quantity and the like of the chemical substances in the rubber are accurately measured and analyzed through specific test methods and technologies, so that the barrier property and the permeation resistance of the rubber product to the chemical substances are evaluated, and important basis is provided for quality control, performance improvement and safe use of the rubber product; The conventional chemical substance penetration test device for rubber products is inconvenient to stabilize and adjust the height of a chemical reagent spray head when in use, so that the distance between the spray head and the surface of the rubber products cannot be changed when the spray head faces the rubber products with different thicknesses.
