Now there are many classifications of glass products, what kind of plexiglass, cooked glass, raw glass... and others, etc. I don't know, how to distinguish and distinguish them，Glass product ?
The simple classification of glass is mainly divided into flat glass and special glass. Flat glass is mainly divided into three types: the pull-up flat glass (with grooves and without grooves), the flat-draw flat glass and the float glass. Due to the uniform thickness of float glass, flat and parallel upper and lower surfaces, high labor productivity and favorable management, float glass is becoming the mainstream of glass manufacturing methods. There are many varieties of special glass, and the following are explained according to the common varieties in decoration:
1. Ordinary flat glass. 1. 3--4 centimeter glass, mm is also called centimeter in daily life. The 3cm glass we are talking about refers to glass with a thickness of 3mm. Glass of this size is mainly used for the surface of picture frames. 2. 5--6 cm glass, mainly used for small-area light-transmitting shapes such as exterior wall windows, door leaves, etc. 3. 7--9 cm glass, mainly used for indoor screens and other larger areas but with frame protection among. 4. 9--10 cm glass can be used for indoor large-area partitions, railings and other decoration projects. 5. 11--12 cm glass can be used for floor spring glass doors and some partitions with a large flow of people. 6. Glass above 15 cm is generally less sold on the market and often needs to be ordered. It is mainly used for the whole glass wall of the outer wall of the floor spring glass door with a large area.
2. Other glass As for other glass, it is just that the author is not officially classified in the industry compared to flat glass when classifying. Mainly: 1. Tempered glass. It is a kind of prestressed glass which is reprocessed from ordinary flat glass. Compared with ordinary flat glass, tempered glass has two major characteristics: 1) The strength of the former is several times that of the latter, the tensile strength is more than 3 times that of the latter, and the impact resistance is more than 5 times that of the latter. 2) Tempered glass is not easy to be broken, even if it is broken, it will be broken in the form of particles without acute angle, which greatly reduces the harm to human body. 2, frosted glass. It is also sanded and processed on ordinary flat glass. Generally, the thickness is less than 9 centimeters, and the thickness is more than 5 and 6 centimeters. 3. Sandblasted glass. The performance is basically similar to that of frosted glass, but the different frosting is sandblasting. Because the two are visually similar, many homeowners and even renovation professionals confuse them. 4. Patterned glass. It is a kind of flat glass made by rolling method. Its biggest feature is that it is transparent and opaque, and it is mostly used in decoration areas such as toilets. 5. Wired glass. It is a kind of impact-resistant flat glass made of metal wire or metal mesh embedded in the glass plate by the rolling method. When it is hit, it will only form radial cracks and will not fall and hurt people. Therefore, it is mostly used in high-rise buildings and factories with strong vibration. 6. Insulating glass. Most of the two pieces of glass are kept at a certain interval by gluing method. The interval is dry air, and the periphery is sealed with sealing material. It is mainly used in decoration projects with sound insulation requirements. 7. Laminated glass. Laminated glass is generally composed of two ordinary flat glass (it can also be tempered glass or other special glass) and an organic adhesive layer between the glass. Ordinary flat glass is also called window glass.
Ordinary flat glass has the properties of light transmission, heat insulation, sound insulation, wear resistance, and climate change resistance, and some have the characteristics of heat preservation, heat absorption, radiation protection, etc., so it is widely used in doors, windows, walls, etc. interior decoration etc.
The specifications of ordinary flat glass are usually divided into 2mm, 3mm, 4mm, 5mm, and 6mm according to thickness, and 8mm and 10mm are also produced. Generally, the thickness of 2mm and 3mm is suitable for civil buildings, and the thickness of 4mm--6mm is used for industrial and high-rise buildings. The defects that affect the quality of flat glass mainly include air bubbles, stones and waves. Bubbles are hidden cavities in the glass body that result from careless handling during the cooling phase of the manufacturing process. Stones, commonly known as lumps, also known as sand, are solid inclusions in the glass, which are the most dangerous defects in the glass. It not only destroys the appearance and optical uniformity of glass products, but also greatly reduces the mechanical strength of glass products. and thermal stability, and may even cause the product to shatter on its own.
Good ordinary flat glass products should have the following characteristics: 1) It is colorless and transparent or slightly greenish 2) The thickness of the glass should be uniform, and the size should be standardized 3) There are no or less defects such as bubbles, stones, waves, and scratches. When purchasing ordinary flat glass, users can put two ordinary flat glass flat together to make them fit each other. In addition, it is necessary to carefully observe whether there are bubbles, stones, waves, scratches, etc. in the glass. The distance between the good quality glass is 60 cm, and the backlight is observed with the naked eye. Large or concentrated bubbles are not allowed, and no corners or cracks are allowed. The maximum angle of the wave bars and lines on the glass surface should not exceed 45 degrees; it is better to have less scratches and sand. Ordinary flat glass is stored in a humid place for a long time, and a layer of white shading will form on the surface, which will greatly reduce the transparency of ordinary flat glass. Pay attention when choosing.
Tempered glass is also called tempered glass. Tempered glass is a glass that is specially treated by a method of rapid cooling after heating to a certain temperature, or a chemical method. The characteristics of tempered glass are high strength, and the bending strength and impact resistance of tempered glass are 3 to 5 times higher than that of ordinary flat glass. It has good safety performance, uniform internal stress, and cracks in the form of a network after being broken. Mainly used for doors and windows, partition walls and cabinet doors. Tempered glass is still resistant to acid and alkali. The general thickness is 2-5 mm. Its size is 400 mm X 900 mm, 500 mm X 1200 mm.
Bending glass: Hot curved glass is a curved glass made of flat glass heated and softened in a mold, and then annealed. Hot-bent glass appears more and more frequently in some advanced decorations, it needs to be booked and there is no stock.
Wired glass is also known as shatterproof glass. Wired glass is made by heating ordinary flat glass to a red-hot softening state, and then pressing the preheated iron wire or wire mesh into the middle of the glass. The characteristics of the wired glass are that it has excellent fire resistance, can block the flame, does not burst when burned at high temperature, and will not cause fragments to hurt people when broken. In addition, the wired glass has anti-theft performance, and the glass is cut and blocked by barbed wire. Wired glass is mainly used for roof skylights and balcony windows.
Laminated glass is a PVB interlayer film with polyvinyl butyral as the main component sandwiched between two pieces of glass. Even if the laminated glass is broken, the fragments will stick to the film, and the broken glass surface of the laminated glass will remain clean and smooth. This effectively prevents the occurrence of debris puncture and penetration and falls, and ensures personal safety. Hot-melt glass, also known as crystal three-dimensional art glass, is a new family that has begun to appear in the decoration industry. Hot melt glass originated from western countries and entered the Chinese market in recent years. In the past, foreign products were all on the market in my country, but now domestic glass manufacturers have introduced products produced by foreign hot-melting furnaces.
Hot-melt glass has become the focus of attention of design units, glass processing owners, and decoration owners due to its unique decorative effect. Hot-melt glass spans the existing glass forms, gives full play to the artistic conception of designers and processors, and integrates modern or classical art forms into the glass, so that flat glass can be processed into various concave-convex and colorful artistic effects. .
