The environment used by polyurethane foaming machine and the problems needing attention
When using a polyurethane foaming machine, it is necessary to avoid use in adverse environments such as dust, vibration, direct sunlight, and corrosive gases.
Secondly, although the polyurethane foaming machine has been carefully designed to reduce the clutter caused by the AC power input, it is also necessary to use it in a low noise environment. If it is unavoidable to use it in its environment, please Install the power filter for better and more reasonable use.
Finally, the instrument will not be used for a long time. Please store it in the original box or similar box in a ventilated room with a temperature of 5 ° C ~ 40 ° C and a relative humidity of not more than 85% RH. The air should not contain harmful impurities of the corrosion gauge. And should avoid direct sunlight.
Note on the use of polyurethane foaming machine
Temperature has a great influence on the foaming machine output and foam quality. Below 30 ° C, the higher the water temperature, the smaller the foam density and the higher the yield. However, when the water temperature exceeds 30 ° C, the foam density is too small, the bubble wall is too thin, and it is easy to defoam, so the yield is reduced. Therefore, the foaming agent aqueous solution temperature is controlled at 20 ° C ~ 30 ° C foaming effect is best.
