Why choose tempered glass for explosion-proof transparent parts?
Transparent parts are a critical material for explosion-proof electrical equipment. When selecting transparent parts, customers always ask what material should be used? Can it be glass? Can it be plastic?
Below, Shenzhen Zhongnuo Testing Technology Co., Ltd. explains to you.
In GB/T3836.1, there are clear specifications for the thermal shock test on transparent components, which is aimed at verifying the thermal stability of glass under rapid cooling conditions. Currently, tempered glass is a material that not only meets these requirements but also offers high cost-performance.
To普及, tempered glass forms an even compressive stress layer on its surface after being heat-treated and quenched. This layer counteracts the tensile stresses that occur on the surface during rapid cooling. Therefore, even if a qualified tempered glass is subjected to rapid cooling, the compressive stress layer will neutralize the stress induced.

Why is it necessary to apply for an explosion-proof certification for the product?
Safety in production is a must. The product is to be used in environments with explosive hazards, which inherently pose a significant risk.
If the equipment itself is not explosion-proof and can easily spark or overheat, igniting surrounding explosive materials, that could be a major issue.
The application for explosion-proof certification of products is to prevent the equipment from being used in hazardous explosive environments.
Also, due to the inherent issues with the equipment itself, it ignited the surrounding environment. Of course, if the equipment failed to explode-proof, that's a different matter.
As the user, if there's a potential explosive hazard on your site, would you opt for explosion-proof equipment or regular equipment?
As a supplier, wouldn't it be more appealing when presenting your products at such on-site venues if they have obtained explosion-proof certification?

Domestic Explosion-Proof Certification
Domestic explosion-proof certification is a compliance inspection conducted on explosion-proof products used in explosive environments (including electrical and non-electrical products).
Issue explosion-proof certificates for products compliant with GB/T3836 standard.
The domestic explosion-proof certification standards are essentially equivalent to the international IEC 60079 standard system.
