BTG high quality Electric heating glass China manufacturer

Electric heating glass is a kind of special glass that is anti-fog and anti-frost by coating a kind of conductive material inside the glass and configuring a safe voltage to set the conductive circuit to connect with the glass. Electric heating glass is suitable for high-end bathing centers, outdoor (flower) vending machines, food exhibition display cabinets, factories that generate increased heat, etc.

  Electric heating glass is safety glass, made of the high-quality original glass. It has anti-fog and anti-frost performance and excellent light transmittance, which does not affect work management and visitor visits. The following are some parameters of electrically heated glass:

>85%

Normal temperature insulation resistance

>100 mΩ

Thermal insulation resistance

≥3 degrees

Temperature difference at each point of heating surface

<3 degrees

The output voltage

12V, 24V, 36V

power

200-300W

Ambient temperature

Minus 40 to 80 degrees Celsius

humidity

0.75

  The following briefly introduces the production process of electrically heated glass:

      1. First, the functional-coefficient is determined. The types of domestic electric heating glass are mainly divided into three categories: monolithic, laminated (safety and explosion-proof), and hollow (sound insulation). According to the performance requirements of customers, the corresponding processing methods are adopted;

      2. Laminated electrically heated glass is made by PVB autoclave, laminated with PVB, PVB film will not be affected by the temperature of electric heating itself, because the melting temperature of PVB film is above 90℃, the melting point is higher, The glass has excellent adhesion performance and high transparency of more than 75%. Therefore, it is an ideal material for laminated electric heating glass. It has the advantages of heat resistance and cold resistance, high mechanical strength, and high light transmittance.

      3. The key point of the hollow electric heating glass is the edge-sealing technology of the two pieces of glass. Only strict edge-sealing can ensure that no air or moisture enters the glass and ensure that the glass does not fog or frost.
