2. Technical Background: Why Is Electric Heating Laminated Glass Needed?
In fields such as automotive, cold storage, marine, and outdoor construction, glass not only needs to have heating functions for defogging and defrosting but must also meet stringent safety and explosion-proof requirements. Traditional electric heating glass is mostly single-layer tempered glass. Once accidentally broken, the fragments will splash and injure people. Ordinary laminated glass, while safe, does not have the active heating and defrosting function.
Mingda Glass's "Electric Heating Laminated Glass" patent technology is an innovation aimed at this pain point. This technology cleverly embeds electric heating elements (such as metal wires, conductive films, or heating meshes) into the PVB or SGP laminated layer, with the outer layer composed of multiple glass layers. This structure not only retains the high safety of laminated glass ("broken but not flying, remains intact" when impacted) but also achieves efficient electro-thermal conversion, capable of rapidly melting ice, defrosting, and preventing fogging.
This patent perfectly combines electric heating function with laminated safety glass, featuring explosion-proof and anti-splinter properties with excellent insulation. At the same time, it can complement the company's existing anti-fog glass and electric heating coated glass technologies to meet the needs of extreme working conditions such as automotive side windows, cold storage explosion-proof doors, and high-speed rail portholes.
