Usually, EVA floor mats are produced for packaging. After receiving the EVA floor mat product, especially during use, there will always be a pungent odor that is difficult to accept. Here, we teach you a method to remove the odor of EVA floor mats: first, take the product back, place it in a ventilated place, let it naturally remain silent for a period of time, and then use a special deodorant through specific chemical reactions, It can effectively remove various odors that appear in the processing and use of EVA foot mats, and can improve the environmental protection level of EVA products.
The development of EVA foot mats can study the mechanical properties of EVA with different cross-linking degrees and the differences in bonding strength with glass/TPT from a mechanical perspective. In this experiment, three different manufacturers of EVA were selected and the test samples were laminated using two laying methods: high-temperature cloth/EVA/EVA/high-temperature cloth and glass/EVA/EVA/backplane; According to the basic principle of cross-linking curing, the laminated samples are laminated and cured by changing the sample lamination parameters (as the lamination time has a certain impact on the adhesion between EVA and glass/TPT, to avoid interference with the test results, the lamination time is kept unchanged in the setting of lamination parameters, and the cross-linking degree of the samples is only changed by adjusting the lamination temperature), and test samples with different cross-linking degrees are prepared; The xylene extraction method is used to determine the crosslinking degree of the sample, followed by tensile testing and peel strength testing of the sample.
Crosslinking degree refers to the degree of curing of EVA small molecules through cross-linking reaction to form three-dimensional network structure. Generally, the cross-linking and curing of EVA is reflected by measuring the gel content of EVA.
The solvent extraction method is used to determine the cross-linking degree of EVA foot mat materials. The testing principle is to extract the EVA sample in a boiling xylene solution, and all non crosslinked EVA is dissolved in the xylene solution. The macromolecules of the crosslinked EVA foot mat material cannot be dissolved, and the cross-linking degree is determined by the ratio of the residual sample amount to the total sample amount.
