        One, ordinary flat glass


        Ordinary flat panel optical glass, also known as window glass known as white glass. White glass has the characteristics of light transmission, heat insulation, sound insulation, wear resistance, and resistance to climate change, and some of the characteristics of heat preservation, heat absorption, radiation and other characteristics, which is widely used in the building of the doors and windows, walls, interior decoration, etc..


        The specifications of flat panel optical glass are usually divided into 2mm, 3mm, 4mm, 5mm, 8mm, and 6mm, 10mm, 12mm, 15mm, etc.. Because he is the most common glass, there is no other special performance, the price is the cheapest, but now the sun is used less.


        Two, toughened glass


        Toughened glass, also known as strengthening optical glass. It is a method that can be used to cool quickly after heating to a certain temperature. Its characteristic is high strength, its bending strength, impact strength is higher than ordinary flat glass 3~5 times. Good safety performance, a uniform internal stress, a net crack after breaking. Mainly used for doors and windows, doors and windows, cabinets. Still, acid and alkali resistant glass. General thickness of 2-15 mm. Glass because of its fragmentation, the moment is a net crack, then the process is very small particles, if the top of the small particles into a small drop out in the end, can greatly reduce the accident, the company believes that the sun should at least be tempered glass


        Three, hollow optical glass


        Hollow optical glass is made up of two or two layers of glass. All around with high strength, high air tightness, the composite binder, two or more pieces of glass and sealing, glass adhesive bonding, the middle is filled with dry gas, the box is filled with desiccant, to ensure that the air of glass film. Its characteristics, due to the retention of a certain cavity, and has good thermal insulation, heat insulation, sound insulation and other properties. Then the high - grade point of the insulating glass inside the rare gas, such as argon, so that its heat preservation function is more superior. Mainly used for heating, air conditioning, muffler facilities of outer glass decoration. Its optical properties, thermal conductivity, sound insulation coefficient should be in line with national standards.


        5+6A+5 hollow double toughened glass means on both sides of the 5 layer is two mm thick tempered glass, the middle is 6 mm hollow glass (Description: hollow glass is the most obvious advantage is insulation, sound insulation function, in the sunshine house is generally used in the side effect, if the sun is to play air conditioning, can greatly save electricity; general sunshine room glass two layer glass is tempered glass, known as hollow double toughened glass, common 6mm hollow 9mm 12mm hollow;


        Four, laminated optical glass


        Laminated optical glass, also known as optical glass, is in between two pieces of glass clip into a layer of the modified polyvinyl alcohol as the main component of PVB film. Even if the glass is broken, the pieces are glued to the film, and the broken glass surface is kept clean and smooth. This will effectively prevent the occurrence of debris into penetration and falling events, to ensure personal safety.


        In Europe and the United States, most of the building glass is used in laminated glass, which is not only in order to avoid damage, but also because the laminated glass has an excellent earthquake resistance. Intermediate film can withstand a hammer, chopping knives and other weapons of continuous attacks, but also in quite a long time to resist bullets penetrating. Its security level is very high.


        A term used in: 5+0.76+5 double laminated tempered glass meaning is on both sides of the two layers of 5 mm thick tempered glass, in the middle of the two layers of PVB film (a layer of film is 0.38 mm thick commonly used two layers of film) (Note: the biggest advantage of laminated glass is broken, the glass is glued to the glass will not fall down, and in the middle of the PVB film can withstand a hammer hitting violently. It is often used in the top of the sun room.
Five, low radiation optical glass


        Low radiation glass, also known as LOW-E (building in accordance with) glass, is a member of the family of coated glass, this glass can reduce the indoor and outdoor temperature difference caused by heat transfer. It's a new generation of coated glass, which can be seen as the same as the float glass to make the outdoor solar energy, visible light through, and like an infrared mirror, the object two times the radiation heat reflection back. In any climate environment, can achieve control of the sun, save energy, heat control and improve the environment. (Note: Low-E glass can be reflected 30-40% of the infrared, thus reflecting the approximately 30-40% of heat energy, so as to achieve energy-saving effect, it is known as warm in winter and cool in summer cool magic glass, used in modern building curtain wall is the most common, with the improvement of people's quality of life, so it gradually was also used in the family sun room)


        Six, nano self cleaning optical glass


        Currently on the market are mainly two: A is superhydrophilic nano self-cleaning optical glass, this self-cleaning glass when it rains in surface can a super hydrophilic state, can easily to float glass surface dust, dirt and taken away, eliminating the need for manual cleaning of the trouble, the market of the superhydrophilic nano self-cleaning glass has Ruijia nano self-cleaning glass; the second is hydrophobic nano self-cleaning glass, the surface of the optical glass like lotus leaf like, water on the surface will form droplets fall down, so that dirt is not easy adherent go up, but its disadvantages more obvious is in a very short period.
