Zhejiang Tongdun New Materials Co., Ltd. is located in Tiantai, Taizhou, Zhejiang. It is a technology-based company specializing in the production of ion exchange membranes. The company has established long-term cooperative relationships with Zhejiang University of Technology, Wenzhou Institute of the University of Chinese Academy of Sciences, etc., and has conducted in-depth and long-term research in the development and application of polymer membranes.
The company's team covers an area of 5000㎡. The existing ion polymer membrane production line is designed with an annual production capacity of 10000000 tons. It has a dust-free workshop and a *** product quality monitoring and testing system. Through *** R & D and testing, the quality stability from raw materials to finished products is strictly controlled.
SGP ionic interlayer film has high strength and shear modulus, with excellent mechanical properties. Its shear modulus is more than 50 times that of ordinary PVB, and its tear strength is 5 times higher than that of ordinary PVB. After laminating with SGP film, when the glass is under stress, the adhesive layer between the two pieces of glass basically does not slide, and the two pieces of glass work together as a single-piece glass of equivalent thickness. As a result, the bearing capacity is twice that of ordinary PVB laminated glass of the same thickness. Meanwhile, under the same load and thickness, the bending deflection of SGP laminated glass is only 1 / 4 of that of ordinary PVB laminated glass. Due to the increased bearing capacity and reduced deflection, the glass thickness can be correspondingly reduced. It is possible to reduce the glass usage by about 40%, which also reduces the self-weight of the curtain wall. This is not only beneficial for the main structure design but also saves materials and energy.
It has good edge stability and can be used exposed without edge sealing:
Edge stability refers to the durability of the edge of laminated glass exposed to atmospheric conditions. SGP interlayer film price, SGP processing technology, PVB laminated glass is not resistant to moisture. It is prone to delamination and separation under the action of water vapor, so edge sealing treatment is required for the exposed edges. In contrast, Tongdun SGP laminated glass has good edge stability, is not sensitive to moisture, and will not delaminate or separate when used exposed. It can be used with open edges without edge sealing. Therefore, SGP laminated glass can be conveniently used for components with exposed edges such as balustrades, canopies, glass curtain walls, and glass sunshades without taking *** edge sealing measures.
After the glass is broken, it retains sufficient residual bearing capacity and will not fall off entirely:
Ordinary PVB laminated glass, especially tempered laminated glass, will produce large bending deformation once the glass is broken, posing a risk of the entire glass falling off. The risk is even greater when the glass is horizontally installed on a skylight. There have been cases of accidental glass falling. SGP interlayer film laminated glass has good integrity. Its tear strength is 5 times that of ordinary PVB interlayer film. Even if the glass is broken, the SGP interlayer film can still bond the broken glass to form a temporary structure after damage. It has small bending deformation and can still bear a certain amount of load without the entire glass falling. This greatly improves the safety of the glass.
Colorless and transparent, not easy to change color. Transparency:
The SGP interlayer film itself is colorless and transparent, and has good weather resistance and is not easy to turn yellow. The yellowing coefficient of the SGP film is less than 1.5, while that of the PVB film is 6~12. Therefore, SGP laminated glass can better meet the architectural art requirements of architects. If ultra-clear glass (low-iron glass) and SGP interlayer film are used to make ultra-clear laminated glass, it will have a crystal-clear optical effect.
Mechanical properties of ionic interlayer laminated glass:
The working performance of several pieces of glass stacked together depends on the mechanical properties of the interlayer (interlayer film). If the shear modulus G and tear strength f of the interlayer film are very small (ordinary PVB laminated glass), when the laminated glass is bent, the interlayer will produce a large amount of slip, and the glass will slide relative to each other. In fact, the interlayer film does not play the role of connecting the glass into a whole. These pieces of glass seem to be stacked together, but actually work independently. The bearing capacity is only the sum of the individual bearing capacities of each piece of glass. SGP film sample test. On the contrary, if the shear modulus G and tear strength f of the interlayer film are very high (SGP laminated glass), when the laminated glass is bent, the slip amount of the interlayer film is extremely small. At this time, several pieces of glass can work together, just like a single piece of glass.
