Structural division of fireproof glass

The fireproof glass is divided into composite fireproof glass (pouring type and composite type. The grouting fireproof glass has good heat insulation performance and the composite fireproof glass has good fire performance) and single fireproof glass.

composite

It is composed of two or more layers of glass original sheet and one or more layers of water-soluble inorganic fireproof glue interlayer.

Fire prevention principle: in case of fire, the glass facing the fire will burst quickly after encountering high temperature, and its fireproof rubber interlayer will foam and expand about ten times one after another to form a hard milky white foam fireproof rubber plate, which can effectively block the flame and isolate high temperature and harmful gases. The finished product can be grinded, perforated and cut with changed ruler.

When applicable to external windows and curtain walls, the design scheme shall consider the combination of fireproof glass and PVB laminated glass. Scope of application: fire doors and windows, fire compartments and fire partition walls in important parts of buildings, rooms, corridors and passages.

Monolithic type

Monolithic fireproof glass is a kind of fireproof glass with single-layer glass structure. Maintain fire resistance integrity within a certain period of time, block open fire and toxic and harmful gases on the fire facing surface, but do not have the effect of temperature insulation and heat insulation.

It is applicable to external curtain wall, outdoor window, daylighting roof, smoke retaining vertical wall, fireproof glass frameless door and partition wall without thermal insulation requirements.

Perfusion type

It consists of two layers of glass sheets (three layers of glass sheets can also be used for special needs), which are sealed with special flame retardant adhesive strips. The fireproof glue poured in the middle is in the form of transparent gel after curing and bonded with glass.

Fire protection principle: in case of high temperature, the transparent gel like fire protection adhesive layer in the middle of the glass will harden rapidly to form an opaque fire protection and heat insulation board. While preventing the flame from spreading, it also prevents the high temperature from transmitting to the back fire surface. This kind of fireproof glass not only has fire and heat insulation performance, but also has excellent sound insulation effect. It can be processed into an arc.

It is suitable for fire doors and windows, building patio, atrium, shared space and fire partition wall of computer room.

Important: the black sealing frame is exposed around the glass, which is suitable for the inlay and installation of the surrounding strip. When it is used for unobstructed positive and west facing external windows, consult the manufacturer in advance for reasonable suggestions.
