(1) Insulating glass classification In two or more glass combinations, the glass and the glass are kept at a certain interval, dry air is provided in the space, and the periphery is wrapped with a sealing material to be processed into hollow glass. There are three kinds of hollow glass production methods: bonding, welding and welding. Due to the limitations of cost and process complexity, the insulating glass of the building is basically produced by glue bonding. Adhesive bonding process is divided into simple sealing and double sealing. Simple sealing is horizontal production. Place a piece of glass on the platform first. Place an aluminum alloy spacer on the glass plate. Place another glass on the aluminum bar. Adjust the position and use manual or glue. The machine is sealed and the edge sealing material is polysulfide rubber. The simple sealed hollow glass is usually called hand-glued insulating glass, and aluminum alloy strips can be observed on the side. (2) Characteristics of Insulating Glass ➀ Optical performance according to the selected glass original film Hollow glass can have a variety of different optical properties. The visible light transmittance range is from 10% to 80%; the light reflectance range is from 25% to 80%; and the total transmittance range is from 25% to 50%. âžInsulating performance Insulating glass has excellent thermal insulation properties Under certain conditions, its thermal insulation can be better than concrete walls. According to statistics, some European countries use insulating glass to save 40 to 50 L of fuel oil per m2 per year than ordinary single-layer windows. âž‚Sound insulation performance Insulating glass has excellent sound insulation performance. Its sound insulation effect is usually related to the type and intensity of noise. Generally, the noise can be reduced by 30 to 44 dB, and traffic noise can be reduced by 3 to 38 dB. The car noise is reduced to the quiet level required by the school classroom. ➃ relatively constant at room temperature, when the temperature reaches the glass surface, condensation will inevitably until frost (hereinafter 0 ℃). This will seriously affect the perspective and lighting of the glass and cause other undesirable effects. Laminated glass is a high-security glass made of PVB film sandwiched between two or more layers of flat glass (or hot bending glass) with high pressure, transparent, high mechanical strength, UV protection, heat insulation, sound insulation, Bulletproof, riot and other features. When the glass is impacted and shattered, the chips are stuck by the PVB and it is not easy to hurt people. It only forms radial cracks, maintains the original shape and visibility, and can continue to be used for a certain period of time. Laminated glass, also known as bullet-proof glass, is widely used in high-rise buildings, curtain walls, ceilings, banks, jewelry stores, schools and villas where safety requirements are high. Laminated glass integrates safety and lighting in one, fresh and elegant. (1) Production process Hollow laminated glass consists of two or more layers of flat glass. With high-strength and high-tightness composite adhesive, two or more pieces of glass are bonded and sealed with sealing strips and glass strips. The middle is filled with dry gas, and the frame is filled with a desiccant to ensure the air dryness between the glass sheets. According to the requirements, various original glass sheets with different properties can be selected, such as colorless transparent float glass embossed glass, heat-absorbing glass, heat-reflecting glass, wire-bonded glass, tempered glass, and frames (aluminum frame or glass strip, etc.). Made by cementing, welding or welding. (2) Physical characteristics Optical performance The hollow glass can have a variety of different optical properties, depending on the glass sheet chosen. The visible light transmittance range is 10% to 80%; the light reflectance range is 25% to 80%; the total transmittance range is 25% to 50%. Insulating performance Insulating glass has excellent thermal insulation properties. Under certain conditions, its thermal insulation can be better than concrete walls. Sound insulation performance Insulating glass has excellent sound insulation properties, and its sound insulation effect is usually related to the type and intensity of noise. Generally, it can reduce noise, that is, it can reduce street car noise to the quiet level required by school classrooms. Dew condensation will occur when the temperature is too low, which will seriously affect the perspective and lighting of the glass and cause other undesirable effects. (3) Conduction characteristics Radiation transmission is the transmission of energy through radiation in the form of radiation. Such radiation includes radiation such as visible light, infrared light, and ultraviolet light, just like the transmission of solar light. The reasonable configuration of the insulating glass and the reasonable thickness of the hollow glass-clad rubber spacer can minimize the transmission of energy through radiation, thereby reducing the energy loss. The presence of active molecules such as water molecules in the air is the main factor influencing the conduction transfer and convection transfer performance of hollow laminated glass. Therefore, improving the sealing performance of hollow laminated glass is an important factor in improving the insulating properties of hollow glass.

What are the characteristics of hollow laminated glass with hollow laminated glass?
Glass can be seen everywhere in reality. Today we are talking about hollow laminated glass . Hollow laminated glass is an integral part of insulating glass. This kind of glass is used in many buildings. It has excellent physical properties and is suitable for installation in many large and medium-sized occasions. The effect of radiation resistance is also very good. At the same time, it also has a good thermal insulation performance, and it has a very good heat blocking effect, but the manufacturing process is relatively complicated. So, what are the properties of hollow laminated glass ? What are the characteristics of hollow laminated glass ? The following Xiaobian will give a detailed introduction for everyone.
