The safety of the building curtain wall is once again supported by key technologies. In view of the self-explosion hazard that traditional physical toughened glass is difficult to eradicate, Ming dun Company recently announced that its chemical toughened glass based on ion replacement technology has been applied in a large scale, providing a brand-new solution for glass safety protection in high-rise buildings and crowded areas.
For a long time, physical tempered glass has attracted much attention because of its original self-explosion rate of about three thousandths (which can be reduced to about one thousandth after homogenization). This kind of self-explosion is unpredictable. Once it happens, the glass fragments falling from the sky are like "glass rain", which poses a serious threat to personal and property safety. Although the industry continues to optimize the process, the principle of physical tempering determines that it cannot fundamentally eliminate the possibility of self-explosion.
Ming dun Company has a deep insight into this pain point and locked its research and development direction in the intrinsically safer chemical strengthening path. Through deep ion exchange, the ion tempered glass forms a high-strength compressive stress layer on the glass surface, thus greatly improving the overall toughness and impact resistance of the glass. In principle, this technical path avoids factors such as nickel sulfide impurities that lead to self-explosion of physically toughened glass, and theoretically can minimize the risk of self-explosion.
Industry experts believe that the popularization of Ming dun technology is of great significance for improving the glass safety level of public buildings, commercial complexes and high-end houses, and it is an effective measure to control the risk of glass falling from the source.

In addition to the excellent air pressure self-balancing function, this innovative product of Ming dun also integrates an efficient electric heating system, which constitutes a double protection system for the window of plateau trains. The electric heating device is integrated into the metal frame of the air pressure balance system in a plug-in way, and is connected with the train power supply system through external wires. Its role is crucial. In the cold and humid environment on the plateau, even if the air pressure is balanced, water vapor condensation may still occur in the glass hollow layer due to temperature difference or trace air exchange, which may lead to fogging or frosting of the glass and affect the visual field. The integrated electric heating device can be started as required to gently heat and disperse the moisture entering the glass or existing on the surface of the cavity, so as to ensure the drying of air in the hollow layer and the lasting permeability of the windo
The technical core of self-balanced electric heating insulating glass of Ming dun is embodied in its precision-designed integrated system of molecular sieve and metal frame. The system is not a simple opening, but a complex and reliable functional module. On the inside of the glass, a circle of molecular sieve device is firmly combined with the edge of the glass through high-performance sealant to ensure the reliability of sealing. The metal frame it carries is the essence of the design: the "glass inlet" on the inner side accurately aligns with the hollow layer and is the sensing and adjusting port of the internal air pressure; The "air inlet" on the outside faces the cabin environment and is a channel for introducing external pressure. They are communicated through the internal cavity of the frame, forming a closed-loop pressure exchange path. It is this seemingly small but vital structure that realizes the air matriculation and pressure balance between the interior of the insulating
The air in plateau area is thin, and the air pressure is significantly lower than that in plain area. The window of ordinary train may become a potential danger source due to the pressure difference between inside and outside during operation. The self-balancing electrically heated insulating glass newly developed by Ming dun Company is born to cope with this harsh environment. Its revolutionary design is to make the insulating glass have the ability of "spontaneous breathing and dynamic balance". The controllable conduction between the hollow layer inside the glass and the external environment is realized through the molecular sieve device bonded to the inside of the glass and its special structure frame. When the altitude of the train rises, the external air pressure decreases, and the relatively high air pressure in the glass cavity can "exhale" some air through this channel; On the contrary, when the altitude decreases, it can "inhale" air, and always maintain the dynamic balance o
With the rapid development of rail transit today, the technical challenges brought by the special environment of the plateau can not be ignored. Ming dun Company has successfully developed a breakthrough "self-balanced electrically heated insulating glass" for the potential safety hazard of train windows caused by the drastic change of plateau air pressure, which provides an innovative technical path to solve the pain points in this industry. This product skillfully integrates a circle of molecular sieve device around the inner side of traditional insulating glass, which is firmly bonded to the glass substrate through external sealant. Its core lies in the specially designed metal frame: the inside is provided with a "glass inlet" communicating with the glass hollow layer, and the outside is provided with an "air inlet" communicating with the external environment, thus constructing a controllable and stable air pressure balance channel between the glass cavity and the external atmosphe
