As the name suggests, frameless fireproof glass is a kind of glass material that can stop the spread of fire. It is different from ordinary glass at home, and its thickness is different. In addition, fireproof glass is formed after special processing and treatment. Then, in the following, Huayue glass Xiaobian will specifically talk about the fire resistance limit of domestic fireproof glass.

Production process of frameless fireproof glass

Cut, clean and dry the original glass sheet; Push the cleaned substrate into the dust chamber for lamination. The lamination shall be stacked in the order of panel glass substrate, PVB film and back plate glass substrate, and the surrounding shall be sealed with edge strips.

Place the laminated glass on the flat press for preloading; After that, dibutyl phthalate is evenly injected from the edge notch reserved for the pre pressed laminated glass, so that there is no air between the two pieces of glass and then sealed.

The fire resistance limit of fireproof glass is divided into five grades: 0.5, 1, 1.5, 2 and 3 hours. In the code under construction and high-level code, the fire resistance limit has three basic requirements: integrity, stability and heat insulation.
