Two common configurations of PI film corona machine

Pi film is a polymer, mainly including aliphatic polyimide and aromatic polyimide

Pi film synthesis has a variety of ways, so that it has a great degree of freedom in the design of synthetic formulations, according to the use of scenarios designed to synthesize different properties of pi materials are widely used in aerospace, microelectronics, nano, liquid crystals, separation membranes, lasers and other different fields.

Pi film has excellent comprehensive performance such as oil resistance, high temperature resistance, low dielectric loss, etc. It has the title of gold film.

From a technical point of view, there are four common types of pi film: black pi film, tan pi film, transparent pi film, corona resistant pi film, and the following three are chemical imine method, which are also the main varieties in the market.

Foldable cell phone using a new generation of display lighting technology, oled in the manufacturing process, need to sputtering electrode or tft material on the flexible substrate, the material is generally high temperature resistant polymers, the most commonly used is high temperature resistant pi material.

So what is the relationship between Pi film and corona machine? Corona machine used in the Pi film industry focuses on solving what problems? Next, let's talk about this.

What are the main problems to be solved in the pi film industry with corona machine first?

The main solution to the corona machine problem Pi membrane base film and the adhesion between the coating, pi if the membrane surface tension is poor pi membrane surface needs to be bonded printing, you need to use the corona machine in advance.

Pi film corona commonly used in two configurations

A: corona roller coating (rubber) ceramic electrodes

Characteristics: dbd double dielectric discharge, low temperature, sparks delicate, suitable for black, yellow, white film

Corona roller with special silicone, static electricity, low cost.

Two: corona roller spray ceramic ceramic electrode

Characteristics: dbd double dielectric discharge, low temperature, spark delicate, suitable for black film, yellow film, white film.

Aluminum roller surface sprayed ceramic, not easy to oxidize, but the cost is slightly higher.
