U-shaped glass curtain wall is an important part of glass, and glass is fragile parts, so management and protection is very important.

Extensive air circulation is necessary in the preservation area. Especially in the high temperature and cycle temperature cycle should be more attention. If conditions do not allow them to be stored indoors, they should be covered with tarpaulin or plastic to protect against wind-blown rain and incoming water, and should be opened regularly to check for moisture condensation.

The glass must be covered with an opaque protective cover, must not be placed directly in the Sun to preserve.

All top and bottom edges of glass should be covered with linoleum and separated by protective cardboard or other linoleum. If the glass is flat, the surface must be covered with linoleum to prevent dust, grit glass or other contaminants.

Its main constituents are silicon dioxide and other oxides. The chemical composition of ordinary glass is NA _ 2sio _ 3, Casio _ 3, sio _ 2 or NA _ 2o · cao · 6sio _ 2, etc. . Widely used in buildings, used for air and light transmission, belongs to the mixture. Coloured glass mixed with oxides or salts of certain metals to give it its colour, and toughened glass made by physical or chemical means.
