A proper amount of antioxidant is added to prevent the premature aging of EVA hot melt adhesive. Because the temperature of the colloid will be oxidized and decomposed when the temperature is high, the addition of antioxidant can ensure that the adhesive properties do not change at high temperature.
In addition to the above materials, some cold resistant agents suitable for the temperature of the cold zone or the heat resistant agents suitable for the tropical temperature can be matched according to the difference in temperature and area.
1. The color requirements of the glue should be different. Yellow hot melt adhesive is recommended if the color has no special requirements on the color itself. Generally, the Yellow hot-melt adhesive is better than the white stickiness.
Two. The surface is treated by the surface. Hot melt adhesive is not as strict as other adhesives for the surface treatment of the finished products, but the dust and oil stains on the surfaces should be properly treated to make the hot-melt adhesive better play the role of adhesion.
Three. Work time. Fast operation is a major feature of hot melt adhesive. The operation time of hot melt adhesive is usually about 15 seconds. With the extensive application of modern production mode -- pipeline, the operation time of hot melt adhesive is shorter and shorter, for example, book binding and speaker manufacturing for hot melt adhesive.
The business time is about 5 seconds.
