We often use all kinds of glass products in our life, such as glass windows, glasses, glass sliding doors, etc. Glass products are both beautiful and practical. They can not only be loved by virtue of their crystal clear surface, but also make full use of their hard and practical physical functions. Some art glass will even make the glass have more patterns and enhance the decoration effect. In this article, we will introduce the use of fireproof glass.

1、 What's the use of fireproof glass

Fireproof glass is a new type of building functional data, which has excellent light transmission function and fire retardant function. It has the common characteristics of high heat resistance, light specific gravity, high light transmittance, no yellowing and no bubbles. The fireproof glass with good function still has excellent fire and flame retardancy at a high temperature above 1000 ℃

The following are the functions and features of fireproof glass:

Composite fireproof glass (or fireproof laminated glass) is made by bonding and compounding two or more single-layer flat glass with intumescent flame retardant cement; The pouring type fireproof glass is made by first sealing the periphery of two or more single-layer flat glass with a frame strip, and then filling the pouring port with fireproof liquid through cementation and sealing; At room temperature and in the early stage of fire attack, composite fireproof glass has the same light transmission function and decoration function as general flat glass; After a fire, with the spread and expansion of the fire, the fire temperature rises, and the composite fireproof glass fireproof interlayer expands and foams when heated to form a very thick fireproof insulation layer, which has the effect of fireproof insulation and fireproof separation. However, the composite fireproof glass generally has small bubbles, poor cold resistance and poor light transmittance, which affect its use effect

Thin coated fireproof glass is made by spraying fireproof transparent liquid on the surface of single-layer or multi-layer flat glass substrate, and then drying and curing. When thin coated fireproof glass meets fire, the fireproof protective layer is heated and expanded to form a fine fireproof protective layer to protect the substrate glass and prevent the spread of fire

2、 What is the difference between energy-saving fireproof window and general window

(1) From the glass function of the window, the glass of the fireproof window must be tempered; The glass of general windows is not necessarily tempered glass

(2) Generally, it is necessary for the glass of fire-proof glass window to have fire-proof mark, while the general glass does not. The fire-proof glass can be filled with fire-proof liquid, which does not affect the fire-proof function of fire-proof window. The light transmittance of glass shall not be less than 75% of that of general flat glass with the same number of layers

(3) From the data, the general fire windows are made of steel, and the general common plastic steel, aluminum alloy and wood. According to the national regulations, the fire windows can be divided into class A, class B and class C. different fire grades have different fire resistance times. The fire resistance time of class a Windows is not less than 1.5 hours, class B windows is not less than 1 hour, and class C windows is not less than 0.5 hours. According to the standard GB16809-2008 fire windows, The sealing materials between the frame and the fireproof glass shall be flame retardant materials, which can achieve the effect of fire prevention and smoke separation in case of fire. However, the general window has no fire resistance time because of its fast heat conduction function, so it can not achieve a good fire prevention effect

(4) From the price point of view, the price of steel fireproof windows for construction is higher than that of general aluminum alloy windows
