Equipment introduction

Plastic nonwoven metallization is a surface treatment technology designed to improve the performance and application range of nonwoven fabrics by metallization. The following is a detailed description of plastic nonwoven metallization technology:

I. Overview

Plastic nonwoven metallization refers to the deposition of metals (such as copper, nickel, silver, etc.) on the surface of plastic nonwovens through specific processes, forming a metal plating layer. This technology combines the flexibility of plastic nonwoven fabric with the metal conductivity, corrosion resistance and other properties of nonwoven fabric to achieve a new function and application.

II, Metal plating method

Plastic nonwoven metal plating methods are mainly the following:

1. Chemical plating: also known as electroless plating, is in the absence of applied current, through the principle of redox reaction, the metal ions in the solution is reduced to metal and then deposited on the surface of plastic nonwoven fabric. This method has the advantages of simple process, low cost, energy saving, etc. It is one of the main ways of metal plating on plastic nonwoven fabric.

2. Electroplating: Electroplating requires external current, through electrolysis to make metal ions in the plastic nonwoven surface reduction deposition. Plating layer uniform, dense, but the cost is relatively high, suitable for plating quality requirements of higher occasions.

3. Vacuum sputtering: the use of high-energy particle bombardment of metal targets, so that the metal atoms from the target surface sputtering and deposited on the surface of plastic nonwoven fabric. This method is suitable for plating high melting point metals and alloys, but the equipment is complicated and the cost is high.
