Low resistance ITO coated shielding glassIt is a new type of glass material that is prepared by electrophoretic deposition on the surface of ordinary glass to form a transparent conductive film with very low resistance. The main characteristics of this glass are high transparency, low resistance, good electromagnetic shielding performance, and good thermal stability.
Glass applications are becoming increasingly widespread in fields such as the Internet of Things, smart homes, and electronic information. In these application fields, due to electromagnetic radiation issues, the electromagnetic shielding requirements for building materials such as windows, doors, and walls are becoming increasingly high. At this time, low resistance ITO coated shielding glass has shown excellent application potential.
1、 The main characteristics of low resistance ITO coated shielding glass include the following:
1. Low resistance: The conductive layer of this glass uses a highly transparent indium tin oxide (ITO) conductive film, and during the coating process, the conductive film can be optimized to have a low resistance value (high conductivity), thereby ensuring high-speed data transmission at high frequencies.
2. High Transparency: During the coating process, any damage to transparency must be avoided, so this glass maintains high transparency and will not be affected even under direct sunlight during the day.
3. Good electromagnetic shielding performance: The conductive film of this glass can block electromagnetic radiation and radiated electromagnetic waves by adjusting the thickness, adding reflective layers and impedance adaptation layers, etc. Within a certain spatial range, it can effectively reduce external interference signals. Therefore, it is widely used in medical, military and other fields.
4. Good thermal stability: The conductive film that has undergone special treatment has greatly improved its thermal stability performance. This glass can withstand ultra-high temperature working environments without reducing its conductivity due to high temperatures.
5. Energy saving and environmental protection: This glass can not only control the heat transfer capacity of the glass according to needs to achieve the effect of regulating indoor temperature, but also avoid adverse effects on the environment, which is energy-saving and environmentally friendly.
Low resistance ITO coated shielding glass is widely used in various fields such as construction, electronic products, automobiles, and aerospace, such as smart doors and windows, display screens, touch screens, solar cells, car electrical enclosures, aircraft windows, military electronic products, and so on. By adjusting the thickness of its conductive layer and coating conditions, it can meet the requirements of different fields for high transparency and good electromagnetic shielding performance of glass.
2、 The preparation process of low resistance ITO coated shielding glass includes the following four main steps:
1. Glass surface cleaning: The glass to be prepared is subjected to a simple cleaning process to remove dirt and rust from the surface, and purify its surface.
2.
Conductive film coatingAccording to the product requirements, the ITO film is uniformly coated on the glass surface through electrophoretic deposition, and its resistance and transparency are controlled according to the requirements.
3. Subsequent processing: Post treatment on the surface of ITO film, such as oxygen spraying, can effectively improve its optical properties and scratch resistance.
4. Inspection and packaging: After the complete preparation process, the prepared products are inspected to ensure that there are no defective coatings or quality issues on their surfaces. Finally, package it for delivery to the user.
