We all know that hot-melt adhesive mesh is not viscous at room temperature. When it is applied to composite materials, it needs to be melted by high-temperature hot pressing before it can become viscous! Three very important dimensions in the entire compounding process: temperature, time, and pressure, have a direct impact on the compounding effect. In this article, I will share with you the possible impact of high temperature on the use of hot melt adhesive omentum.
The hot melt adhesive omentum needs to be heated to a certain temperature to melt, and the temperature has a great influence on the hot melt adhesive omentum. We know that there are many types of hot melt adhesive reticular membranes, and hot melt adhesive reticular membranes with different melting points have different requirements for compounding temperature. In order to improve the composite efficiency, some manufacturers may use the method of increasing the temperature of the machine to shorten the heat pressing time. From a logical point of view, this method seems to be pretty good. However, many problems will occur during actual operation.
First of all, if the temperature is too high for the melting point of the hot-melt adhesive membrane, it is easy to cause the phenomenon of aging, deterioration, and carbonization. Once this happens, it will seriously affect the composite effect of the product.
Second, too high temperature may cause the phenomenon of glue penetration and glue seepage. If the glue is stuck to the machine, if it can not be cleaned in time, it will cause damage to the machine and indirectly affect the composite effect.
Third, although too high temperature can shorten the hot pressing time, on the other hand it will also cause a lot of consumption. If the production efficiency is not high, it will only cause unnecessary energy waste.
In general, it is not recommended to increase the temperature of the machine while using hot-melt adhesives for omentum lamination. Perform compound operations according to the requirements given by professionals.
