In the production process of melamine impregnated paper, the impregnation process is not only one time, but when performing the second impregnation, it is different from the first impregnation, and there are many precautions. In order to help everyone improve work efficiency, the following gives us a detailed introduction of the key points of secondary impregnation of melamine impregnated paper:
First, in the glue formulation design and preparation process selection, according to the glue reaction mechanism and impregnated paper on the glue requirements, to use the excellent performance of the glue preparation process.
Second, another important point is that when adjusting the glue, we must choose the most appropriate curing agent, penetrant, release agent, in the original glue by adding the appropriate proportion, so that production efficiency is improved. It is still very different from the first impregnation.
When melamine impregnated paper is subjected to secondary impregnation, it is different from the first time parameters such as temperature, operating speed, and wind speed.
