What is a polyurethane foam machines, a lot of people it is not very understanding, it is used in the chemical life activities, or more. Today we'll take a look at the composition of the raw material of polyurethane foam machine, as well as understand the equipment structure foaming machine is how to understand these, help us to better use it. Now we learn next!
The first is an isocyanate R-NCO, commonly known as the black material - because the isocyanate-stained hand, will form a black spot, a few days leave. The second is to other materials such as polyether polyols, catalysts, silicone oil, frame chain agents, flame retardants, blowing agents according to the proportion of premix is completed, called polyether polyols, also known as white material. People often like to use the letters A component, B component to call the isocyanate and polyol. Polyurethane foam machines in the workshop, black and white material mixed with each other can make the entire polyurethane foam inside the foam, causing unmanageable mess.
Polyurethane foam machine A, B two components liquid, the exact ratio and high speed stirring, by two high-precision metering pumps, the A, B two-component material was delivered to each mixing head. After vigorous stirring speed, so that the material was uniformly ejected form the desired product. Polyurethane foam machine from the power aspect classification can be divided into: high-speed impeller-type, high-pressure air type, blowing the low pressure type. A complete polyurethane foam machine consists of the following systems: material flow systems, measurement systems, pneumatic systems, heating systems, cleaning systems, the mixing device.
To introduce the above main raw material for polyurethane foam machine composition, the ratio of raw materials all have certain requirements, if you do not meet the requirements, their production did not help. Also know the structure of the composition of the polyurethane foam machine, welcome to our company to buy the right equipment, like him to support it!
