With the steady progress of national and global energy conservation and emission reduction strategies and people's pursuit of natural comfort, tranquility and quality life, the vacuum insulated glass with super heat insulation, extreme silence and anti-condensation has been gradually known by the public and gradually entered the fields including curtain wall, civil construction and high-end refrigeration appliances (refrigerators). Facing the dazzling vacuum glass products and technologies in the market, ICESUN vacuum glass provides the following key notes to help customers understand and select reliable vacuum insulated glass products.
*Principle and structure of vacuum insulated glass
Vacuum insulated glass is separated by a 0.2mm-0.4mm high support, and the edges of the two layers of glass plates are sealed with low-temperature welding technology, and then the air is discharged. Vacuum insulated glass is a new generation of energy-saving glass products with excellent performance such as super heat insulation and extreme anti-noise feature.
*What are the characteristics of vacuum insulated glass?
Vacuum insulated glass should have reliable product performance, of which the most important is heat insulation performance and noise reduction feature. Moreover, vacuum insulated glass should have safety. For example, it should conform to the characteristics of safety glass. Besides, vacuum insulated glass should also be able to bear certain external force, so that it can bear certain wind pressure load or temperature difference load without failure in use. By the way, ICESUN vacuum glass has very strong wind resistance(9 grade wind resistance) and its temperature difference can be up to 100 degree. Finally, the performance of vacuum insulated glass products should be stable in long-term use, and ICESUN vacuum glass has very long lifespan, up to 50years.
*What tests should vacuum insulated glass pass?
Vacuum glass needs to undergo three types of tests: safety test, aging test and on-line quality test. Safety test includes: impact fragment test, shotgun bag impact test and wind pressure resistance test; Aging test includes: weather resistance test and sunlight aging test; Quality inspection includes: air tightness inspection and on-line performance inspection. ICESUN vacuum glass has unique vacuum eye technology which can help people check the lifespan of glass windows easily.
*What certificates should be required for vacuum insulated glass?
Qualified vacuum insulated glass should obtain three kinds of certificates, including product performance certificates, safety certificates and qualification certificates. Performance Certificates mainly include thermal insulation performance, noise reduction performance and wind pressure resistance performance; Safety certificates mainly include: safety glass product certificate, ROHS directive test item certificate; Qualification certificates mainly include: 3C certification, green building materials product certification, etc. The third-party authoritative certificate shows that the manufacturer's vacuum insulated glass products are guaranteed in terms of performance, quality and application.
Vacuum glass adopts low melting point technology and aerospace grade welded glass edge sealing. With the same expansion rate, no air leakage and the service life of vacuum glass up to 50 years. The fulcrum in the glass room is placed automatically by the machine, and the glass is clamped automatically when vacuumizing, with a vacuum degree of 10-4Pa.
*How to determine whether the manufacturer is a qualified vacuum glass supplier?Firstly, the vacuum glass products produced by the manufacturer should comply with the provisions of the national standard of vacuum glass; And the manufacturer should have a well functioning ISO quality management system. What's more, the manufacturer should have sufficient supply capacity and abundant successful application cases.
As an epoch-making high-performance energy saving glass product, the wide application and popularization of vacuum glass will greatly reduce the consumption of building materials and energy consumption and carbon emission in the use process in the construction field, and bring healthy and sustainable quality life to the public. The mission of ICESUN vacuum glass is to cool the earth by 1℃.
