The five factors influencing the hot melt effect of hot pressing compound machine are as follows:
1、 If the color of the hot melt rubber particles is not required by the glued material, the yellow hot melt particles are selected, and the viscosity is good.
2、 Only the dust and stain on the surface of the glued object can be treated clean, so as to give full play to the effect of hot melt adhesive.
3、 The viscosity of the hot melt adhesive strip is divided into the viscosity at the early stage and the later stage. Only when the viscosity in the early stage and the later stage are together, the hot melt adhesive strip and the subsequent material can be kept stable. This point in the hot melt adhesive production, we should do well.
4、 The hot melt adhesive strip of Shaanxi hot press compound machine is sensitive to temperature, and it will soften when it is higher than a certain temperature. When the temperature is lower than a certain temperature, the hot melt adhesive will become brittle. Therefore, when selecting the hot melt rubber particles, the change of the ambient temperature of the hot melt rubber particles must be considered.
5、 The fast bonding time is a major feature of hot melt particles. The working time of hot melt adhesive is about 15 seconds. With the wide application of modern production mode - assembly line, the working time of hot melt adhesive is shorter and shorter. For example, the operation time of book binding and speaker manufacturing for hot melt adhesive is about 5 seconds
