Notes for use of polyurethane foaming machine

1. When using the polyurethane foaming machine, it is necessary to avoid using it in the adverse environment such as dust, vibration, direct sunlight and corrosive gas.

2. Although the polyurethane foaming machine has been redesigned to reduce the clutter interference caused by AC power input, it still needs to be used in a low-noise environment as far as possible. If it is really impossible to avoid using it in its environment, please install the power filter. In order to facilitate better, reasonable use.

3. If the instrument is not used for a long time, please store it in the original packing box or similar box in a ventilated room with the temperature of 5℃~40℃ and the relative humidity of no more than 85%RH. The air should not contain harmful impurities of the corrosion measuring instrument and should avoid direct sunlight.

4. Temperature has a great influence on the production and quality of polyurethane foaming machine. Under 30 degrees, the higher the water temperature, the smaller the foam density, the higher the yield. However, when the water temperature is over 30 ° c, the foam density is too small and the foam wall is too thin, which is easy to defoaming, so the yield is reduced instead. Therefore, the temperature of the aqueous solution of the foaming agent is controlled at 20 ° c to 30 ° c, and the foaming effect is the best.
