In building glass, I believe we all know more about Low-E glass and tempered glass. In fact, fireproof glass is also one of the widely used glasses in building glass. Fireproof glass is a kind of special glass, which should be used for fireproof glass doors (to be used for machine rooms, staircases, partitions, etc.), fireproof windows (to build external wall windows, internal refuge rooms, etc.), smoke retaining vertical walls (to be used for building ceilings), curtain walls, etc.

Fireproof glass has a variety of uses. In order to adapt to different building styles, we need to produce a variety of colors. Through years of development, fireproof glass has a complete range of colors: Tongming (white), blue, gray and other colors. So how do you get these colors?

Blue fireproof glass is usually obtained from Low-E glass through special processing. Blue can show a broad, calm, vast and quiet atmosphere. The deployment and construction color can achieve different functions, and it is also the color preferred by customers.

Gray fireproof glass can also be processed through Low-E glass. Gray is a series of colors between black and white. Gray reflects a trace of dark beauty and solemn atmosphere.

Transparent fireproof glass uses many colors. Transparent glass has good permeability and daylighting. It can see through the whole space at a glance, reflect the vastness of the space and create a vast visual effect.

The fireproof glass of other colors can be obtained by clamping different color films in the fireproof glass, which can be customized according to the needs of customers.

The above is only part of the coloring method. Some manufacturers can make different colors by adding 0.4% ~ 0.7% colorant to the glass ingredients. Generally, the colorant is metal oxide. However, the color of fireproof glass not only depends on the colorant, but also needs to adjust the valence of elements through the melting temperature and the nature of furnace flame. This method is more complex.
