With the steady advancement of the “carbon peak and carbon neutral” national energy conservation and emission reduction strategy, and people’s comfort in nature, the pursuit of a quiet and leisurely quality life, the vacuum glass that is super heat-insulating, extremely quiet, and not easy to condense gradually
It is well known by the public and has gradually entered the fields of commercial, civil buildings and high-end refrigeration appliances. Face the market .A dazzling array of vacuum glass products and technologies, the editor summarizes the following key precautions to help you know and choose reliable vacuum glass products.
1. Principle and structure of vacuum glass
Vacuum glass is separated by two or more sheets of flat glass with supports, and the periphery is sealed and then vacuumed to make a vacuum layer is formed between the two pieces of glass; The vacuum glass uses the performance of the vacuum layer to transfer almost zero heat and sound.,Thus becoming a new generation of energy-saving glass products with excellent performance such as super heat insulation and extreme silence.
2.What are the characteristics of vacuum glass?
Vacuum glass must have reliable product performance, the most important of which are heat insulation and noise reduction performance;
Secondly, vacuum glass must be safe, for example: it should meet the characteristics of safety glass; vacuum glass should also
It must be able to withstand a certain external force, so that it can withstand a certain wind pressure load or temperature difference load during use
Without failure; finally, the vacuum glass product should maintain its performance stability in long-term use.
3. What tests does the vacuum glass need to go through?
Vacuum glass needs to undergo three types of tests: safety testing, aging testing and online quality testing. An comprehensive tests include: impact fragment test, shotgun impact test and wind pressure test; aging test includes: Weather resistance test, solar aging test; quality inspection includes: air tightness test, online performance test.
4. What certificate does vacuum glass need to obtain? What does the third-party authoritative certificate indicate?
Qualified vacuum glass must obtain three types of certificates, product performance certificate, safety certificate and qualification class certificate. Performance certificates mainly include heat insulation performance, noise reduction performance and wind pressure resistance performance; safety certificate the book mainly includes: safety glass product certificate, RoHS directive test project certificate; qualification certificate mainly includes Including: 3C certification, green building materials product certification, etc.
The third-party authoritative certificate shows that the manufacturer’s vacuum glass products are in terms of performance, quality, and application.It is guaranteed.
5.What are the advantages of using metal edge sealing for vacuum glass?
The metal edge sealing material has a low melting point, so during the edge sealing and sealing process, it will not cause the annealing of the tempered glass; secondly, the metal material has better ductility, when the vacuum glass is subjected to temperature differences or external forces during use. When the additional load is generated, the metal edge sealing material can withstand greater deformation, so the vacuum glass of the metal edge sealing is not easy to fail. These advantages of metal edge sealing make the quality of vacuum glass more reliable and performance better.
6. How to determine whether the manufacturer is a qualified vacuum glass supplier?
First, the vacuum glass products produced by the manufacturer must meet the requirements of the national vacuum glass standards; secondly, the manufacturer should have a well-run ISO quality management system; finally, the manufacturer should have sufficient supply capacity and large-scale enterprise 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 in the construction field and energy consumption and carbon emissions during use, and bring the public health, enjoyment, and sustainable quality. life.
