Imitation electroplating aluminum paste, environmentally friendly aluminum paste

 

The electroplating process has a certain degree of pollution, so the replacement of traditional electroplating with a new process has been implemented, and has achieved rapid development in recent years. It is a common production method for pigments made of aluminum paste to obtain a beautiful appearance through the coating process. The following three processes are implemented:

 

Dip coating process: Put the objects to be constructed in the paint and immerse them to dry. After drying, the corresponding anti-corrosion and appearance effects can be achieved. Common coating systems include self-drying acrylic, thermosetting acrylic, alkyd resin systems, etc., depending on the construction requirements and performance requirements after coating. This process is mainly suitable for parts, standard parts, frames, etc. with small volume and unit weight.

 

Manual spraying process: Many large frames, angle irons, pipes, etc., do not have enough volume to place items in the dip coating tank or there is not enough automatic spraying line available, so they can only be sprayed manually. This type is basically based on air-drying resin systems, mainly acrylic resins that require hardness, weather resistance, and scratch resistance. Those that do not require these are more inexpensive alkyd resin systems and petroleum resins. System-based.

 

Automatic spraying line process: Many small frames, regular angle irons, etc. are suitable for automatic lines. This type of application is also divided into self-drying type and baking type. This type is more complicated, high-end and low-end are available, but Mainly low-end.

 

No matter what type of application, leafing aluminum paste is needed, and there are a few non-leafing aluminum pastes.
