Composition and advantages and disadvantages of laminated glass

Laminated glass is a kind of multi-layer composite structural glass composed of a plastic film layer between two pieces of glass. This type of glass is widely used in construction, automotive, aerospace, and many other fields. Laminated glass has good permeability, high mechanical strength, light resistance, heat resistance, cold resistance and other properties. Laminated glass has good impact resistance and safety performance when broken, when the laminated glass is broken by impact, the debris is still firmly standing on the sandwich, not easy to hurt.

It has the following advantages

1. Strong security. The presence of laminated plastic film can keep the laminated glass intact when broken, avoid splashes, and reduce personnel and property losses.

2. Good sound insulation effect.Laminated glass has a layer of sealing material in the middle, so it can block sound waves when it encounters noise.

3. Uv resistant. Laminated glass can prevent ultraviolet light from causing certain damage to the human skin, and it can also prevent the fading of some valuable furniture or displays in the home.

4. Strong anti-wind pressure and anti-theft performance. The plastic film in the sandwich has good tensile property, can resist external forces, and the structure of the laminated glass itself provides a certain guarantee for the anti-theft performance of the window.

It has the following disadvantages:

1. The cost is high. Compared to single-layer glass, laminated glass is more expensive to manufacture

2. The weight is large. Due to the presence of sandwich film, the weight of laminated glass is heavier than that of ordinary glass.

3. The stability of laminated glass is relatively poor, and it is particularly easy to burst when processing, which requires relatively high construction technology for production workers, and the machinery for the production of glass should also be very exquisite.

4.Water leakage is easy to occur in the rainy season, and the glass surface is particularly easy to blur, which has a certain impact on the appearance.
