Shatter-resistant glass and wire glass are not understood by most people. Tomorrow, the editor will inform you what exactly is laminated glass? Why wire glass is used for doors and windows. Wired glass is a special glass formed by pressing a wire mesh into a semi-liquid glass ribbon during the rolling process. Its characteristics are superior fire resistance, can block flames, will not explode when extinguished at low temperature, and will not form fragments to hurt people when broken. In addition, the laminated glass has anti-theft function, and the broken glass is also blocked by barbed wire. Therefore, laminated glass is mainly used for curtain walls, partitions, glass sheds, doors and windows, etc.

    Its advantage is that it has higher strength than ordinary glass. When the glass is impacted or the temperature changes drastically, it will be broken but not broken, cracked but not scattered, preventing small pieces of corners and corners from flying out and hurting people, such as the spread of fire and the heated glass At the same time, it can still maintain a fixed shape and play a role in isolating the fire. Even if it is broken, the wire or net can hold the fragments and it is difficult to collapse and break. When the flame is pierced, it can block the intrusion of flame and fire powder, and it has the effect of avoiding spreading and burning from the opening. In addition, because the screened glass is not easy to penetrate, it has a certain anti-theft effect when used for door and window glass.

    Laminated glass can also be used as a fire protection material for secondary doors and windows. Ordinary glass is susceptible to heat and rupture and shatter when a fire breaks out, forming air activity and fire spreading. Although the glass with wire mesh bursts in a fire, it will not collapse and penetrate due to the support of metal wire or mesh. It can maintain the integrity at a considerable level, avoid air activity, and have a better barrier to the spread of fire. effect.
