Precautions for the operation of polyurethane foaming machine

Precautions for the operation of polyurethane foaming machine

  1. Due to the high ambient temperature, the pressure will partially evaporate, so you should first open the exhaust cover to release the air pressure, and then open the drum cover.

  2. If the polyurethane foaming machine has certain flame retardant requirements for the foam, a certain flame retardant needs to be added. Add 15% to 20% of the common flame retardant for white materials, then add the flame retardant to polyurethane A, and then need to stir well to foam.

  3. The polyurethane foaming machine adopts manual foaming, accurately weighs polyurethane A, B combined polyurethane, presses the mixer into the container with a 2000rpm stirrer, and then pours it into the mold. Release time depends on product requirements, foam thickness, etc.

  4. When skin comes into contact with mixed polyurethane A, wash with soap and water. Polyurethane foaming agent is used for polyurethane B material (with certain irritation). Do not inhale steam, do not splash on skin and eyes, if splashed on skin and eyes, you need to use a medical cotton cloth first, then rinse with plenty of water for 15 minutes, and then rinse with soap or alcohol.

  Buying skills of polyurethane foaming machine

  As we all know, polyurethane foaming machines need to be paid attention to when purchasing, so what should be paid attention to?

  1. Fully understand the type of foaming machine

  If the material is introduced into the gas by slowly rotating the blades, the bubble output is small and the foaming efficiency is low; the high-speed impeller type cannot control the foam on the high-speed rotating impeller, and the foam is not uniform. High-pressure and medium-low pressure models have high foam production rates with uniform and small bubbles.

  2. The basic parameters of the foaming machine:

  Output: The output is the amount of bubbles produced, it needs to be slightly higher than the required amount of bubbles, so the amount of bubbles should be limited based on approved calculations and cannot be restricted.

  Capacity of the polyurethane foaming machine: The capacity of the polyurethane foaming machine is the total installed power, which is important to the total power of the computer circuit.
