【LUCK GLASS】What are the characteristics of embossed glass and safety glass?

Glass is an item that we often touch and use in our daily lives. From daily necessities such as glass cups to architectural decorative materials such as glass curtain walls, glass has made great contributions to the development of world civilization. For example, what is the name of the craft glass we often hear about, and what is the name of the craft glass commonly used in manufacturing, and what is its outstanding performance. So what are embossed glass and safety glass, and what are the categories of glass partitions? Let's take a look.

1. Characteristics of embossed glass and safety glass

Embossed/Patterned glass, also known as patterned glass or knurled glass, is a type of flat glass made by rolling method. The manufacturing process is divided into single-roller method and double-roller method. The single-roller method is to pour the glass liquid onto the rolling forming table. The table top can be made of cast iron or cast steel. The table top or roller is engraved with patterns. The roller rolls on the glass liquid surface, and the embossed glass is then sent to the annealing kiln. The double-roller method of producing embossed glass is divided into two processes: semi-continuous rolling and continuous rolling. The glass liquid passes through a pair of water-cooled rollers and is pulled forward to the annealing kiln as the rollers rotate. Generally, the surface of the lower roller has concave and convex patterns, and the upper roller is a polished roller, so as to make embossed glass with patterns on one side. The physical and chemical properties of embossed glass are basically the same as those of ordinary transparent flat glass. It only has the characteristics of light transmission and opacity in optics, which can soften the light and has a private shielding effect and a certain decorative effect. Embossed glass is suitable for indoor partitions of buildings, bathroom doors and windows, and various occasions where it is necessary to block the line of sight.

Safety glass refers to laminated glass, tempered glass, and insulating glass made of them that meet national standards. Among them, the comprehensive performance of laminated glass and insulating glass made of laminated glass is particularly good. Generally, civil tempered glass is made by heat treating ordinary glass to increase its strength by 3 to 5 times. It can withstand external impacts of a certain energy or temperature changes without breaking. Even if it breaks, the whole piece of glass breaks into small obtuse particles similar to honeycombs, which are not easy to hurt people, so it has a certain degree of safety. Tempered glass cannot be cut, and needs to be cut to size before tempering, and has the characteristic of "self-explosion". According to different uses, tempered glass can be divided into various types such as full tempered glass, semi-tempered glass, regional tempered glass, flat tempered glass, and curved tempered glass.

As a kind of safety glass, laminated glass will not produce sharp fragments that hurt people after being broken by impact due to the bonding effect of the PVB film sandwiched between the two pieces of ordinary glass. At the same time, the sound insulation and sunlight control performance of its PVB intermediate film make it a new building material with energy-saving and environmental protection functions: the use of laminated glass can not only isolate the 1000~2000 Hz matching noise that can penetrate ordinary glass, but also block more than 99% of ultraviolet rays and absorb heat in the infrared spectrum. As a laminated glass that meets the performance of new building materials, it is bound to play a huge role in the use of safety glass.

2. What are the categories of glass partitions?

1. According to the main material type of glass: single-layer glass partition, double-layer glass partition, laminated glass partition, vacuum glass partition.

2. According to the material of the partition frame: aluminum alloy frame glass partition, stainless steel frame glass partition, steel structure frame glass partition, wooden keel frame glass partition, plastic steel frame glass partition, steel aluminum structure frame glass partition, steel and wood material frame glass partition, frameless pure glass partition.

3. According to the size of the frame material: 26 glass partitions, 50 glass partitions, 80 glass partitions, 85 glass partitions, 100 glass partitions, customized special specification frames, etc.

4. According to the track form: fixed glass partition, mobile glass partition, folding glass partition.

5. According to the height: high glass partition, low glass partition, screen partition.

6. According to the functions and properties of glass: safety glass partitions, fireproof glass partitions, ultra-white glass partitions, explosion-proof glass partitions, artistic glass partitions, etc.

Glass

Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate complex salt, which is an amorphous solid with irregular structure. It is widely used in buildings to block wind and light, and is a mixture. There are also colored glass that shows color by mixing certain metal oxides or salts, and tempered glass made by physical or chemical methods.

Embossed glass

Embossed glass is also called patterned glass or knurled glass. It is generally divided into embossed glass, vacuum coated embossed glass and color film embossed glass. Single-sided embossed glass has the characteristics of light transmission but not see-through, and has privacy. When used as door and window glass for bathrooms and toilets, the embossed side should be facing outward.
