Classification of glass materials Glass materials can be divided into two categories.
The first type is glass plate, which is mainly used for the part that needs lighting in the decoration, such as flat glass, embossed glass, frosted glass, coated glass, carved glass, toughened glass, etc., which can be based on the requirements of different parts and different decorative effects. Choose.
The other is glass bricks, mainly used for glass partitions, glass walls and other projects, mainly hollow glass bricks. It can be divided into single-chamber and double-chamber, and also has a variety of specifications such as square tiles and rectangular tiles. Its surface shape is also very rich, and it can be selected according to the needs of decoration.
Quality evaluation of glass materials
1. Inspection of glass plates. The appearance quality is mainly to check the flatness, to observe the presence or absence of air bubbles, inclusions, scratches, line and fog and other quality defects. The glass with such defects will deform during use, which will reduce the transparency and mechanical strength of the glass. The thermal stability of glass and glass should not be used in engineering. Since the glass is a transparent object, visual inspection can basically identify the quality.
2. Inspection of glass processed products. In addition to testing according to the requirements of the flat glass, the quality of the processing should also be inspected to check if the standard size, processing accuracy, and pattern definition meet the requirements. At the same time, no defects are allowed at the edge.
The appearance quality of hollow glass bricks is not allowed to have cracks, opaque unmelted materials are not allowed in the glass blanks, and welding and bonding defects between the two glass bodies are not allowed. Visually, the brick body should not have lamellar stripes due to inhomogeneities in corrugations, bubbles, and glass blanks. The outer surface of the glass brick should be less than lmm in the large surface, less than 2mm in the convex, and the weight should meet the quality standards. There should be no surface warpage and defects such as notches and burrs. The angle should be squared.
Tip: The indoor 8 parts must use the safety glass "Building Safety Glass Management Regulations" in the provisions of the interior decoration, including class ceiling (including skylights, lighting ceiling), ceiling, stairs, balconies, platform corridors, and bathroom shower partition, Safety glass must be used in eight parts of the bathtub partition and the bathroom door.

How can the quality of glass materials be
Glass has the special properties of light transmission, perspective, sound insulation, and heat insulation. With the continuous improvement of people's living quality, the application of glass products in decoration has become increasingly widespread. At present, glass doors, windows, partitions, and glass decorations are very popular in home decoration.
