How to choose high quality polyurethane high pressure foaming machine

Pu high pressure foaming machine is widely used in making furniture, float subsequently, household appliances, construction, transportation industry, shoe leather, sports health care industry, industry, packaging industry products, such as choosing high quality pu high pressure foaming machine not only greatly reduce the production cost, and can produce high quality products, so how to choose the high quality pu high pressure foaming machine? The high - pressure polyurethane foaming machine of high quality needs to have judgementPolyurethane high pressure foaming machineQuality capability.

In the determination of the quality of polyurethane high-pressure foaming machine, the first test from the foam quality of foam, should be given priority to in three aspects, namely foam fineness, foam uniformity, foam discharge water.

1. Foam fineness refers to the size of bubble diameter. The smaller the bubble diameter is, the smaller and thicker the foam is, and the better the stability of the foam is.

2. Foam uniformity refers to that the bubble diameter and size should be uniform and consistent. The more uniform the bubble diameter and size is, the narrower the distribution range is, the more uniform the stress on the product is, and the better the application effect is.

3. the amount of foaming water refers to the amount of foaming agent aqueous solution produced after the foam burst. The lower the amount of foaming water, the lower the foam water content, indicating the better the foaming performance of the foaming machine.

High pressure polyurethane foam machine in the above three aspects can meet the requirements, the most simple method should be tested to confirm approval. In the selection of polyurethane foaming machine, the requirements of foaming machine issued by the foam must be "foam more water less" spongy fine foam, and uniform and delicate.
