Information

Because the strength of toughened glass is relatively high, and after being broken, the fragments will be broken into uniform small particles and there is no common glass knife-like sharp corner, so it is called safety glass and is widely used indoors and outdoors. Tempered glass is obtained by cutting ordinary annealed glass to the required size, then heating it to a near softening point, and then performing rapid and uniform cooling. After tempering, uniform compressive stress is formed on the surface of the glass, and tensile stress is formed inside, which greatly improves the performance of the glass. The tensile strength is more than 3 times of the latter, and the impact resistance is more than 5 times of the latter. It is precisely this characteristic that the stress feature has become an important sign to distinguish true and false tempered glass, that is, tempered glass can see colored stripes on the edge of the glass through the polarizer, and black and white can be seen on the surface of the glass. Alternate spots. The polarizer can be found in the camera lens or glasses. Pay attention to the adjustment of the light source when observing, so that it is easier to observe.

TPS performance characteristics-better precision control [ 2021-04-25 ]

Since the tps system can support stepless width adjustment from 2mm to 20mm, the system supports the automatic adjustment of the final thickness of the insulating glass

TPS performance characteristics-long sealing life [ 2021-04-25 ]

Especially due to the frequent changes of ambient temperature and pressure, the gas in the hollow cavity of the hollow glass is always in a state of thermal expansion or contraction, so that the sealant is in a state of stress for a long time. For the traditional double-channel sealing system, the action of this force will cause the deformation of the sealant and the loss of its function

TPS performance characteristics-extremely low water vapor transmission rate [ 2021-04-25 ]

TPS adopts special butyl rubber mixed molecular sieve to directly extrude and form, the consistency of the sealing material is good. At the same time, because the thermoplastic spacers can also form an intimate chemical bond with glass and silicone glue, the structure of the insulating glass is more stable and the bond is stronger.

TPS performance characteristics-excellent thermal insulation performance [ 2021-04-25 ]

The side sealing materials of insulating glass include aluminum strips, steel and stainless steel materials, organic silicon materials, etc. Due to the different thermal conductivity of the material itself, the heat conduction formed at the side of the insulating glass is also very different. The lower the heat transfer coefficient, the lower the heat transfer coefficient. The better the thermal insulation performance, the more obvious the energy-saving effect.

Comparison of tempered glass and ordinary glass [ 2021-03-29 ]

The reason why tempered glass is called safety glass is widely used in high-rise building doors and windows, glass curtain walls, indoor partition glass, daylighting ceilings, sightseeing elevator passages, furniture, glass guardrails, and windows that open to the outside of high floors. This is because tempered glass is in After being broken, the fragments will not become sharp corners, but will be broken into uniform small particles, reducing the possible harm to the human body.

Comparison of tempered glass and semi-tempered glass [ 2021-03-29 ]

Semi-tempered glass is also called thermally strengthened glass. Semi-tempered glass is a variety between ordinary flat glass and tempered glass. It has some of the advantages of tempered glass. For example, the strength is higher than ordinary float glass, which is twice that of ordinary float glass while avoiding the flatness of tempered glass. The disadvantages of poor temperature, self-explosion, and crushed as a whole once destroyed. When the semi-tempered glass is damaged, it cracks radially along the crack source, and generally has no tangential crack propagation, so it can still keep the whole body without collapsing under normal circumstances.

Glass industry: optimistic about special glass and glass fiber [ 2021-03-29 ]

Glass demand: From January to August, the sales area of commercial housing was 527 million square meters, an increase of 6.7% year-on-year, and the growth rate fell 36.2 percentage points year-on-year. The negative impact of commercial housing sales began to spread to the construction field. Since May 2010, the growth rate of newly started area, construction area and completed area of housing has declined consistently. If the growth rate of the newly started area of commercial housing declines and gradually spreads to the completed area, it will further affect the demand for flat glass.

What are the reasons for the spontaneous explosion of tempered glass? [ 2021-03-29 ]

1. Self-explosion classification of toughened glass Since the birth of toughened glass, it has been accompanied by self-explosion. The spontaneous explosion of tempered glass can be expressed as the phenomenon that tempered glass breaks automatically without direct external action. Tempered glass can explode spontaneously during tempering processing,

Glass industry analysis report: demand recovery and slow production resumption bring prices continue to rise [ 2021-03-29 ]

Flat glass is a cyclical industry. From historical data, it goes through a cycle approximately every 3 years. The industry has a typical "ketchup effect". When the ketchup bottle is continuously tapped, the sauce is often not poured out, and then a large pile is suddenly poured out. This is related to the triple cycle characteristics of the glass industry: real estate cycle,
