fireproof glass structure

Hello everyone, I'm Xiaobian. Today, I will introduce fireproof glass to you. The following content is organized by Xiaobian, and the relevant content is for reference

fire-proof glass

Fireproof glass is divided into composite fireproof glass (perfusion type and composite type, grouting fireproof glass has good thermal insulation performance, and composite fireproof glass has good fireproof performance) and single-piece fireproof glass.

Compound

It is composed of two or more layers of original glass sheets with one or more layers of water-soluble inorganic fireproof glue interlayers.

Fire prevention principle: When a fire occurs, the glass facing the fire surface will burst soon after encountering high temperature, and the fireproof glue interlayer will foam and expand about ten times successively, forming a hard milky white foam fireproof glue board, which can effectively block the flame and isolate the high temperature and harmful effects. gas. The finished product can be edged, punched, and cut with a ruler.

When it is suitable for external windows and external curtain walls, the design scheme should consider the combination of fireproof glass and PVB laminated glass. Scope of application: Fireproof doors and windows, fireproof partitions and important parts of fireproof partition walls in building rooms, corridors and passages.

Monolithic

Single-piece fire-resistant glass is a fire-resistant glass with a single-layer glass structure. Maintain the integrity of fire resistance for a certain period of time, block open flames and toxic and harmful gases on the fire surface, but do not have the effect of thermal insulation.

It is suitable for exterior curtain walls, exterior windows, skylights, smoke-blocking vertical walls, fire-resistant glass frameless doors, and partition walls without thermal insulation requirements.

perfusion type

It consists of two layers of original glass (or three layers of original glass for special needs), and is sealed with special flame-retardant adhesive strips around it. The fireproof glue poured in the middle is solidified into a transparent jelly and bonded to the glass.

Fire prevention principle: After encountering high temperature, the transparent jelly-like fireproof adhesive layer in the middle of the glass will harden rapidly to form an opaque fireproof insulation board. While preventing the spread of the flame, it also prevents the conduction of high temperature to the back fire side. This kind of fireproof glass not only has fireproof and thermal insulation properties, but also has excellent sound insulation effect. Can be processed into arc.

It is suitable for fire doors and windows, building patios, atriums, shared spaces, and computer room fire partition partition walls.

Important note: The black sealing frame is exposed around the glass, which is suitable for inlaid installation of peripheral pressure strips. When used for unobstructed positive sun and west facing exterior windows, consult the manufacturer in advance for reasonable advice.
