What should we pay attention to when using polyether amine technology?

Polyether amine technology is often used as a kind of foaming agent after polyether amine is generated. Of course, it is because of the existence of such products that we can achieve a good effect when using products. However, when we use it in styrofoam, what should we pay attention to? Let's have a simple understanding.

A, styrofoam is a moisture curing foam, polyether amine technology in the production of polyether amine, it needs to be used in accordance with normal, spray it on the wet surface, the greater the humidity, curing faster. The uncured foam can be cleaned by cleaning agents, while the cured foam is removed by mechanical means (sand grinding or cutting). The cured foam will be yellowed after UV irradiation. It is recommended to use other materials (cement mortar, paint, etc.) on the surface of the solidified foam. After using the spray gun, please clean it with special cleaning agent immediately.

B. when replacing the material tank, shake the new tank evenly (at least 20 times), remove the empty tank, and quickly replace the new material tank to prevent the connection port of the spray gun from curing. All of these need the support of polyether amine technology to achieve a good effect.

C, the flow control valve and trigger of the spray gun can control the size of the foam flow, and turn off the flow valve in a clockwise direction when the injection is stopped.

1. The amine group of polyether amine is more active than alcohol, and polyether link provides flexibility.

2. It can be used as surfactant to modify various resin types.

3. Polyetheramine has low viscosity, color and vapor pressure, and is completely miscible with most solvents, including water. It can obtain tough, clear and impact resistant coatings, casts, adhesives, etc. the coating surface is free from the common whitening phenomenon of other amine curing agents.

4. The color of polyether amine is light, which can increase the peel strength and flexibility in epoxy adhesive.

Polyether amine has special molecular structure, but these structures give it excellent comprehensive properties. At present, its types include a series of products with single function, double function and three function. It has been widely used in many fields, such as polyurea spray, large-scale composite material and epoxy resin curing agent.
