AI Technical Summary
In highly corrosive environments, existing metal-rubber sheets suffer from poor adhesion due to rust, oil, dust, and other impurities remaining on the metal surface, hindering the bonding between the adhesive and the metal surface. This results in peeling problems during use. Furthermore, the sheets lack sufficient corrosion resistance, making them susceptible to corrosion in highly acidic or alkaline environments, thus losing their protective effect.
It uses plastic sheets with adhesive and rubber layers coated on both sides, and an anti-sticking layer is coated on the rubber layer. The plastic sheets are made of polyimide, polyetheretherketone, or polyphenylene sulfide, which have excellent high temperature resistance, radiation resistance, chemical corrosion resistance and high mechanical strength.
It improves the adhesion of plastic-rubber composite sheets, enhances corrosion resistance, adapts to various chemical media, is wear-resistant, reduces vibration and noise, and is suitable for a wide temperature range, making it applicable to sealing equipment in chemical, petroleum and other industries.
