Description

technical field [0001] The invention belongs to the field of basalt fiber surface treatment equipment, and in particular relates to a basalt fiber continuous chemical nickel plating device and an application method. Background technique [0002] Basalt fiber is an inorganic non-metallic material mainly composed of silica, alumina, and alkali oxides. It has excellent properties such as acid and alkali resistance, mechanical properties and temperature resistance. However, as a non-conductor material, it has high resistivity and low dielectric constant, which limits the application of various excellent properties of basalt fiber in energy electronics, electromagnetic shielding, electrostatic protection and other fields that require better electromagnetic properties. application development. [0003] In order to expand the application field of basalt fiber, the surface treatment of basalt fiber is required to make it have good electromagnetic properties. At present, the surfac...

Problems solved by technology

However, most of the traditional electroless plating pretreatment steps are sensitization-activation treatment containing noble metal ions, the process steps are cumbersome, and the sensitization solution and activation solution not only have certain corrosiveness to the container, but also have certain harm to the environment and human body. Hazardous

[0005] Although the above patents on electroless plating disclose various processes for performing electroless metal plating on the fiber surface, there are few records in the existing literature for the industrial preparation of continuous chemical plating metal layer fiber equipment, especially for continuous basalt fiber Nickel-plated equipment is rare

Therefore, in order to meet the production requirements of nickel plating on the surface of basalt fiber, it is necessary to solve the existing equipment and technology that cannot meet the requirements of continuous nickel plating of basalt fiber
