Water based pu glue Treatment method for sole degumming
The sole is degummed and non-sticky. Generally speaking, this is the treatment agent that needs to choose the correct material. Oily materials and release agents are relatively heavy materials. When using, be sure to clean or adjust the treatment agent to 3-5% RFE curing agents, such as rubber materials, these must be roughened in place. Pay attention to the build-up and under glue when brushing.
The upper is degummed and non-sticky. Generally speaking, this requires the leather to be roughened. After laminating the leather, it is lightly sanded with sandpaper. Nylon materials and horseskin are treated with RFE. Also pay attention to glue build-up and under glue when brushing.
The upper and sole have poor adhesion. The general solution is to increase the oven temperature to reduce the line speed. This is to ensure that the adhesion is performed within the sticky maintenance time. The amount of curing agent added is controlled at 5% and stirred evenly, which can prevent cold air from blowing on the rubber surface.
There is a phenomenon of drawing on the upper and bottom. In this case, it is generally necessary to reduce the line speed. The amount of curing agent is controlled at 5% and stirred uniformly. The bottom application is completed as quickly as possible. Press in place. The comparison between oil-based glue and water-based pu glue in the early stage of production will be worse, but the later stage is better, and water based pu glue is environmentally friendly and odorless, which can save production while providing a healthy working environment for shoemakers.
