How to configure heating functions to ab glue dispensing machine
When we configure a double-liquid glue dispensing filling machine to improve production, we need to configure it according to our actual needs. Whether the glue filling machine needs a heating function depends mainly on the characteristics of the glue and the environment in which it is used.
1. When customer are using two component silicones , normally no heating is required. The characteristics of silicine compound itself are high temperature resistance and low temperature resistance, and heating has no effect on its fluidity and viscosity.
2. When the glue is epoxy resin or polyurethane compound, if the materials is transparent, generally there is no need to heat it, because the viscosity of transparent glue is very low. Even if the temperature is lowered, its fluidity will still be good.
3. If the epoxy resin and polyurethane compound are deep colors like gray , black... , under normal circumstances, glue A is heated, and glue B is not used, because glue B is a curing agent, and its viscosity is very low, generally 50-100CPS, and its fluidity is very good. And glue A generally has a higher viscosity, in the range of 3000-20000CPS. If it is A glue from northern customers, it is best to add heating, because the temperature in the north will be relatively low in winter. If it is a customer from Guangdong, even if the temperature is not very low in winter, it will have no effect if it is not heated.
Epoxy resin and polyurethane materials will have better fluidity and lower viscosity after heating, but heating will increase the power of the machine. The power of the heating coil is basically above 1000W, which will increase the cost of electricity consumption. Therefore, whether the glue dispensing filling machine needs to be equipped with a heating function depends on customer's production actually .
