Glass 1-3mm Coated Steel Particles-Light Blue

toughened glass
Toughened glass is also called the tempered glass.It is to use physical or chemical method, in a compressive stress layer is formed on the surface of glass, glass itself has high compressive strength, will not cause damage.When glass by external force, the stress layer can be part of the tensile stress in offset, avoid the glass broken, although toughened glass internal in large tensile stress state, but the interior of the glass without defects exist, not build in a damage, so as to achieve the goal of increased the strength of the glass.
Toughened glass is flat glass secondary processed products, the processing of toughened glass can be divided into physical toughened method and toughened method.
Physics of toughened glass is also known as quenching of toughened glass.It will be common flat glass heated to nearly glass in the heating furnace softening temperature (600 ºC), through its own to eliminate internal stress deformation, and then remove the glass furnace, with a long nozzle to both sides of the high pressure cold air blowing glass, make it quickly and evenly cooled to room temperature, can be made of toughened glass.This kind of glass in the internal tension and external compressive stress state, once the local damage, stress release, will glass is broken into many small pieces, these small pieces of no sharp edges, not easy to hurt.
Chemical tempered glass is through changing the chemical composition of the surface of the glass to improve the strength of the glass, are generally of toughened with ion exchange method.Its approach is to build the silicate glass containing alkali metal ions, immersed in molten state in lithium (Li +) salt, make the Na + and K + ion of glass surface with Li + ion exchange, Li + ion exchange forms on the surface, because the expansion coefficient of Li + is less than Na +, K + ions, thus causing in the process of cooling outer smaller and inner contraction is bigger, when cooled to room temperature, the glass is also in the inner tension, outer state of compression, the effect is similar to physical toughened glass.
Toughened glass with high intensity, its compressive strength can reach more than 125 mpa, 4 ~ 5 times larger than ordinary glass;Impact strength is high, with steel ball method, 0.8 kg of steel ball falling from 1.2 m high, glass can be intact.
The elasticity of toughened glass is much bigger than common glass, a 1200 mm x 350 mm x 6 mm tempered glass, stress can occur after the 100 mm bending deflection, when the external force to remove, still can recover, and common glass bending deformation can only have a few millimeters.
Good thermal stability, under thermal shock, not easy to occur crack is another characteristic of toughened glass.This is because the compressive stress of toughened glass can offset part of the tensile stress because of the heat shock.Toughened glass to heat shock, the maximum safe working temperature is 288 ºC, 204 ºC can withstand the temperature change.
Because of toughened glass has good mechanical properties and thermal stability, so in construction engineering, transportation and other fields has been widely used.Flat tempered glass used for building doors and Windows, wall, curtain wall and window, furniture, etc., curved glass is often used in cars, trains and aircraft, etc.
That should be paid attention to when using is toughened glass can not cutting, grinding, edge horn cannot touch attack extrusion, need according to the size of the ready-made specification selection or put forward the concrete design drawings into processing customization.Used in a large area of glass curtain wall on toughened glass to be control, select half toughened glass, its stress too much, in order to avoid shock caused by wind load and explosive.
Depending on the glass, glass can be made into ordinary tempered glass, absorption of heat, the color of toughened glass, toughened glass steel hollow glass, etc.

Brief Introduction of the Company

 

Deyuanheng Glass Sand Co. Ltd., located in Yongqing county, was established on Aug. 15th, 2009 based on the former manufacturing factory (set up in March, 2003). With 5 years of efforts for development, we have witnessed another company founded- Haixing Glass Products Co. Ltd. located in Beiguzhuang Industrial District of Yongqing county, only 100 kilometers away from Tianjin port.

 

The products of the company have expanded from the original glass to more comprehensive series of glass products. Currently, it has become only one of the most large-scale manufacuturer of stained glass products based on the waste glass by recycling methods. The range of products include: colored glass blocks, colored glass sand, colored glass beads, water drop glass beads and other colored glass products as well as glass beads, glass powder, glass microballons.

 

The annual production of glass products are over 30,000 tons with the selling both at home and abroad, including U.S.A., Britain, Brazil, Germany, Spain, South Africa, UAE, Japan, Korea, India, Malaysia, Taiwan and other 20-plus countries and regions, winning a renowned worldwide reputation. Since its establishment, the company has been aimed at the quality guarantee and honesty tradition, facing the market demands and conducting sincere cooperation with clients.

 
Welcome your highly interest.
