What is safety glass?


Safety glass is a type of glass that does not break after severe vibration or impact, and even if it breaks, it is not easy to hurt people.


It is used for doors and windows of automobiles, airplanes, and special buildings. The use of safety glass in buildings to withstand bullets or debris caught in hurricanes of up to 100 kilometers per hour is of particular importance in modern buildings with a glass main structure. Common types of safety glass include laminated glass, tempered glass, etc.


Safety glass refers to tempered glass, laminated glass, and other glass products processed by the combination of tempered glass or laminated glass by the current national standards, such as safety insulating glass, etc. Safety glass according to different needs can be made of ordinary glass, tempered glass, heat-enhanced glass, but also can be made of insulating glass. Safety glass has good security, impact resistance, and penetration resistance, with anti-theft, explosion-proof, impact resistance, and other functions.

Place of use security glass


Security glass is usually used in some important facilities, such as bank doors, valuables display cabinets, prison and correctional facility doors, and windows. These parts are likely to be attacked continuously by groups of bandits with various kinds of murderous weapons. The high-strength security glass can resist penetration for a period of time, giving enough time for other devices to respond.


Bulletproof glass is made of multiple layers of glass with multiple layers of PVB interlayer bonded and processed, or it can be made of ordinary glass with bulletproof film, which can withstand the strong impact of a handgun, rifle, or even a bomb blast.


In urban terrorist bombings around the world, glass fragments are the main cause of injuries. When an explosion occurs, glass shards fly across the room like rain, and can even fly several kilometers away, causing more than 90% of the number of people injured. Laminated glass in the event of an explosion, even if shattered, can still be intact in the frame, greatly reducing the damage to people from glass fragments.

The main varieties of safety glass are tempered glass, laminated glass, bulletproof glass, anti-theft glass, fire glass, wire glass, and protective glass and film glass, etc. Among them, the film glass simultaneously tempered glass, laminated glass, bulletproof glass, anti-theft glass, fireproof glass, laminated glass, and part of the function of protective glass, is a new type of building materials.


YS manufactures&supplies tempered glass, YS tells you what is tempered glass?


The tempered is quenched and strengthened glass. When the glass is uniformly heated to the softening temperature, it is made by quenching with a cooling medium such as high-speed air. This glass surface has uniform compressive stress, which can improve the glass's mechanical strength and thermal shock resistance.


When using air as the cooling medium, it is called tempering; when using oil and other liquids as the cooling medium, it is called liquid tempering; when using molten salt as the cooling medium, it is called salt bath tempering.


According to its degree of rigidity and the shape of the product, it can be divided into completely tempered, regional tempered, semi-tempered, flat tempered, and curved tempered varieties.


The bending strength of tempered glass is 3 to 5 times greater than untreated glass, up to 150-250 MPa, and the thermal stability is increased by 3 to 4 times, which can withstand the rapid change in temperature from 200 to 250°C. When broken, it forms particles without sharp edges, which cause little harm to the human body and is the most widely used safety glass.

Due to the use of the new toughening process, such as roller conveyor or air cushion plane toughening; the development of new cooling media, such as the addition of special solid media to the compressed air, highly volatile liquid, and the use of silicone oil media and solid contact method, etc., significantly improve the cooling efficiency of the cooling medium, can be toughened 1.7 ~ 3 mm thin glass and further improve the strength of the glass, reduce the weight. Also developed printing, spraying color glaze glazed tempered glass.


The tempered glass in the building is mainly used indoors, windows, windows, enclosures, and finishing materials.


YS manufactures&supplies laminated glass, YS tells you what is laminated glass?


Laminated glass products are made of transparent polyvinyl butyral film or other adhesive materials sandwiched between two or more pieces of glass, which are heated and glued together under pressure. When impacted, because the middle layer has elasticity and strong bonding, it can improve the impact strength, and when broken, its fragments do not fall and splash, which can effectively prevent or reduce the injury to humans.


In addition, you can also use heat-absorbing glass, heat-reflective glass, color glass, and conductive film glass, etc., to make special laminated glass. It is mainly used in vehicles and buildings with special requirements.


Laminated glass as a kind of safety glass in the impact of broken, due to its two pieces of ordinary glass sandwiched between the bonding effect of the PVB film, will not be like ordinary glass broken to produce sharp fragments hurt people.

At the same time, its PVB interlayer has the performance of sound insulation and sunlight control, which makes it a new building material with energy-saving and environmental protection functions: the use of laminated glass can not only isolate the anastomosing noise of 1000~2000 Hz that can penetrate ordinary glass, but also it can block more than 99% of ultraviolet rays and absorb heat in the infrared spectrum.


As a new building material in line with the performance of laminated glass is bound to play a huge role in the use of safety glass.


YS manufactures&supplies bulletproof glass, YS tells you what is bulletproof glass?


With tempered glass, chemically enhanced glass, laminated (mesh) glass, and high-strength organic materials (such as oriented plexiglass, polycarbonate, etc.), and the lamination process made of composite glass.


According to different requirements, different materials can be used to form different composite structures, to achieve the performance of being able to resist gunfire at a certain distance and prevent theft. It is generally used in buildings with special bulletproof or anti-theft requirements and border guard observation posts, etc.

YS manufactures&supplies fireproof glass, YS tells you what is fireproof glass?


Refers to a transparent gel coalesced between two pieces of glass when encountering high temperature, decomposition, and absorption of a large amount of heat so that the glass can remain temporarily unbroken and prevent the spread of fire glass. It is generally used for fireproof partitions or fire escapes in building complexes. In addition, the glass hollow block, laminated (net) glass also has a certain effect on fire prevention.

YS manufactures&supplies wire glass, YS tells you what is wire glass?


Calendering molding, embedded in the glass inside the metal wire (mesh) glass. When the glass is broken, the fragments are still hanging on the metal wire (net) and do not fall. In case of fire, it can stop the spread of flame for a short time and delay the expansion of fire and can be used as windows and smoke partition walls of fireproof buildings. Generally used as transparent protective structures of buildings, skylights, and transparent fences in courtyards, parks, zoos, and sports grounds.

YS manufactures&supplies protective glass, YS tells you what is protective glass?


This refers to glass that can effectively shield the human body from hazards such as X-rays and thermal neutrons. It is highly transparent and contains lead, which absorbs high-energy rays, and boron, which absorbs thermal neutrons. It is stable to high-energy rays and does not change color, precipitate, or destroy after irradiation. It is mainly used for research, production, and application of atomic energy and isotopes in the parts of the building that require protection.

YS manufactures&supplies film glass, YS tells you what is film glass?


It is a glass product with organic film, and when it is broken under strong enough impact, the glass fragments can adhere to the organic film and not fly apart. Film glass is a new type of energy-saving safety glass. According to its function, glass film is mainly divided into privacy film, decorative film, heat insulation, and energy-saving film, explosion-proof film, and bulletproof film, among which explosion-proof film and bulletproof film belong to the ranks of typical safety film, but their energy-saving effect is relatively poor.
