Common building glass on the market

Different architectural parts will use different architectural glass. Especially in the application of external windows, because of the transparent lighting and heat resistance of the glass to keep warm. In different occasions, glass with different functions is also needed. Tempered glass, insulating glass, heat-reflective glass and other glass with various functions came into being. Today, SINOY editor will take you to learn about several commonly used architectural glass.   1. Tempered glass Tempered glass is made by heating float glass to near the softening point in a tempering furnace, and then rapidly and uniformly cooling it, forming uniform compressive stress on its surface, increasing its mechanical strength, and effectively improving the wind pressure and impact resistance of the glass Performance, improve the thermal shock resistance of glass. Tempered glass is widely used in places that require relatively high mechanical strength and safety. Such as glass doors and windows, building curtain walls, glass furniture, indoor partitions, elevators, furniture, etc.   Performance characteristics of tempered glass 1) Safety: When broken, it splits into small obtuse-angle particles similar to honeycombs, which hardly cause serious harm to the human body. When ordinary glass is broken, it is a sharp large piece of fragments, which is easy to cause serious harm to the human body. 2) High strength: 4-5 times stronger than ordinary glass of the same thickness. 3) Stable heat resistance: With good thermal stability, the temperature that can withstand is about 3 times that of ordinary glass of the same thickness, and it can withstand temperature changes of 200°C. Therefore, it can play a short-term fire prevention effect in the event of a fire. 4) Large interference: 3-4 times larger than ordinary glass of the same thickness. When tempered glass is loaded, its maximum tensile stress is not located on the surface of the glass like ordinary glass, but at the center of the tempered glass plate.   2 Laminated glass Laminated glass is a composite glass made by sandwiching a tough polyvinyl butyral film (PVB) between two or more pieces of glass, which is made through high temperature and high pressure. Because the toughness of the PVB film is very good, when the laminated glass is violently impacted and broken by an external force, the film layer will absorb a large amount of punching skills and make it attenuate rapidly. Because the laminated glass is difficult to be broken down, even if the laminated glass is broken, the glass The fragments basically adhere to the film, keeping the fragments on the entire laminated glass from falling off, so it becomes the real safety glass. Laminated glass made of transparent PVB film, its appearance and installation method are basically the same as ordinary glass, and it is durable. It is widely used in building lighting roofs, canopies, high-end curtain walls, doors and windows, shop windows, furniture, elevators, etc.   Performance characteristics of laminated glass 1) Safety: The laminated glass installed on the building is subject to any external impact, even if the glass is broken, it can be kept in the original frame completely, and has a certain function of sheltering from wind and rain. 2) The noise-reducing PVB film has an obstructive effect on sound waves, thereby reducing noise and reducing noise interference at work or home. 3) Anti-ultraviolet rays: Great blocking effect on ultraviolet rays in sunlight (up to 99% or more) and avoid ultraviolet radiation. Therefore, it can protect valuable indoor homes or artworks from fading caused by ultraviolet rays. 4) Bulletproof and explosion-proof: the use of multilayer laminated glass can produce various levels of bulletproof and explosion-proof glass. 5) Security: Because glass cutters cannot be used to effectively cut the installed laminated glass, and the use of other tools to penetrate the laminated glass takes a long time and the sound is loud, it is difficult and easy to enter the room by cutting or breaking the laminated glass. It is found that it has a strong resistance to vicious destruction, theft and violence. 6) Protection against hurricanes and earthquakes: Due to the high toughness and strong adhesion of laminated glass, even if the laminated glass is broken, the fragments will still remain in place. It is more suitable for use in hurricane and earthquake areas.     3 Insulating glass Insulating glass is a glass product made of two or more pieces of glass separated by a certain width of space with an aluminum frame filled with molecular sieve adsorbent, bonded and sealed with butyl glue, and then sealed with silicone glue or structural glue. Has good sound insulation, heat insulation, heat preservation, anti-condensation and other effects. Insulating glass is widely used in various building curtain walls, doors and windows, indoor partitions or freezers, etc. Thickness of insulating gl

The difference between painted glass and colored mirror

How to distinguish between painted glass and colored mirror? Is it different? First of all, let’s take a look at the difference between the following two pictures   Presumably, you should not be able to distinguish the differences between these two types of glass and mirrors. Now there is a editor from SINOY to take you to understand the similarities and differences between painted glass and colored mirrors.   Colored mirrors refer to various colored mirrors made of high-quality colored float glass as the original instead of ordinary float transparent glass. Color mirrors are divided into two categories: color aluminum mirrors and color silver mirrors. Namely color aluminized glass mirror and color silvered glass mirror. The colors sold in the market are blue, green, gray, brown, gold, black, pink, etc.   Painted glass is also called back-painted glass in the industry, divided into flat painted glass and frosted painted glass. Spray paint on the back of the glass and bake it in an oven at 30-45 degrees for 8-12 hours. In many places where baking varnished glass is made, natural drying is generally used, but the adhesion of naturally dried paint is relatively small, and in a humid environment Easy to fall off. According to different production methods, baking varnished glass is generally divided into: paint sprayed glass and colored glazed glass. In colored glazed glass, it is divided into low temperature colored glazed glass and high temperature colored glazed glass. Paint-sprayed glass has bright colors when it is first used, mostly in single color or partial color registration with multiple layers of saturated colors. It is often used indoors. When outdoors, it will peel off the paint after being exposed to wind, rain and sun.   Similarities between the two The common point of the two is that they are all glass deep-processing products. The color mirror has good finish and the coating is relatively stable; the painted glass looks like a color mirror from the front, but the paint is prone to bubbles and trachoma cannot be installed in the air   Can you now distinguish between the two pictures above which is the lacquered glass and which is the color mirror?   The above is the report brought by SINOY editor Angus.

The difference between silver mirror, grey mirror and bronze mirror

Mirrors are inorganic non-metallic materials that are widely used and have a wide range of applications. They can be used in construction, daily use, art, instrumentation and other fields, and the types are very rich. In addition to the commonly used silver mirrors and aluminum mirrors, there are also bronze mirrors, grey mirrors and no bronze mirrors. Now let the editor of SINOY take you to understand the difference between silver mirror, grey mirror and bronze mirror. Silver mirror Silver mirrors are made by adopting modern advanced mirror-making technology, choosing special-grade float glass as the original film, and performing a series of processes such as sensitization, silver plating, copper plating, and protective paint. It is characterized by pure imaging, high reflectivity, good color reproduction, bright and natural images, and durable even in humid environments. It is a replacement product for aluminum mirrors, and its scope of use extends far beyond aluminum mirror products. Widely used in furniture, handicrafts, decoration, bathroom mirrors, makeup mirrors, optical mirrors, and car rearview mirrors.   Grey Mirror Gray mirror is a widely used decorative mirror. In general, it is divided into color mirror ranks. The basic process of its production is to plate a layer of silver powder on the gray glass, and then paint one or more layers of high corrosion resistance environmentally friendly paint, and through a series of beautification and cutting processes.   Bronze mirror The bronze mirror is a silver mirror made of citrine or brown glass. The color of the bronze mirror looks like golden . In many cases, the bronze mirror designed as an ornament will have some special geometric shapes, which have a very good decorative effect. . So it is widely used in furniture, handicrafts, decoration, etc.   Therefore, they do not have a major difference in materials on the market, but there are certain differences in manufacturing processes.   The above is the editor of SINOY editor Angus
