Polyurethane foaming machine k5000is usually used in chemical life activities, many people do not know much about it, today we will take a look together, about it


What is the raw material composition and what is the equipment structure.


raw material:

1. Isocyanate R-NCO, commonly known as black material.

  

2. The other raw materials, such as polyether polyols, catalysts, silicone oils, chain-linking agents, flame retardants, and foaming agents, are pre-mixed according to proportions, and are called combined polyether polyols, or white materials.


Equipment structure:

1. The two component raw liquids of A and B of the polyurethane foaming machine are accurately mixed and stirred at high speed, and the two component liquids of A and B are sent to the mixing head by two high-precision metering pumps.


After high-speed stirring, the material liquid is uniformly and sprayed out to form the desired product.


2. Classification of power: high-speed impeller type, high-pressure air type, blast medium-low pressure type.


3. Polyurethane foaming machine system composition: material flow system, metering system, gas system, heating system, cleaning system, mixing device.


The above are the raw material composition and equipment structure of the polyurethane foaming machine. In addition, the proportion of the raw materials are all certain requirements. If it does not meet the requirements, it will not help the production.
