Recently, "Ming dun", a leading domestic special glass enterprise, announced that its entire line of products have been fully tested and certified by a number of national and high-standard third-party authoritative organizations, including National Safety Glass Testing and Certification Center, China Railway Research Institute, Biltong Standard Technical Service Co., Ltd., Electronic Meteorology Research Institute and China Ordnance Industry No.208 Research Institute. This not only means that Ming dun products completely meet and exceed the international, national and industrial standards in terms of physical performance and safety indicators, but also marks that they have reached a brand-new industrial height in terms of production quality system and technical reliability.
Ming dun always adheres to the development concept of "quality as the shield and innovation as the way". From the traditional bullet-proof, riot-proof and fire-proof glass to the cutting-edge microelectronic, self-cleaning and AR anti reflection glass, the birth of each product has gone through a strict closed loop from research and development, production to finished product inspection. The endorsement and trust of many heavyweight scientific research and testing institutions has undoubtedly provided the strongest quality assurance and confidence for customers in the downstream rail transit, high-end buildings, security and military industries, new energy applications and other fields.
"Obtaining these authoritative certifications is an affirmation of our past efforts and a responsibility for our future development." The relevant person in charge of Ming dun said, "We will take this as the cornerstone, continue to promote technological innovation and quality improvement, and provide safer and smarter glass solutions for a wider range of industry applications."
Hot Product
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
