tempered glass Reinforced glass is safety glass
cheap tempered glass/Reinforced glass is safety glass. cheap tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, it first offsets the surface stress, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, impact, etc. Pay attention to distinguish it from glass fiber reinforced plastic.
Product Certification: The activity of certifying that a product or service complies with a specific standard or other technical specification by a third party that can be fully trusted. Product certification is divided into compulsory certification and voluntary certification. All standardization preparations (ISO) define product certification as "a third party through inspection and evaluation of the company's quality management system and sample type tests to confirm whether the company's products, processes or services meet specific requirements, and whether it has continuous and stable production that meets the standard requirements. product capability and a procedure for giving written evidence.”
Homogenized cheap tempered glass is a product after homogenization of cheap tempered glass. The hot dip treatment process is to place the cheap tempered glass in a hot dip furnace, keep the heating rate no higher than 1.5°C/min, and continue to heat up to about 300°C for several hours to promote the phase change of the nickel sulfide (NiS) crystal inside the cheap tempered glass. Or the expansion of hard silicon crystals causes the glass to break, and the intact glass is taken out after it is gradually cooled.
The heat-dipping process makes the cheap tempered glass, which could explode after being used, artificially shattered in the factory's hot-dip furnace in advance, thereby reducing the self-explosion of the cheap tempered glass in use after installation. The self-explosion rate of conventional size glass can be reduced to less than 0.1% after heat dipping.
Glass maintenance precautions:
1. Users need to pay attention to protecting the corners of the heat soaked tempered glass: if the corners of the heat soaked tempered glass are damaged, the risk of the glass self-explosion will increase exponentially. Because the stress points of the heat soaked tempered glass are all concentrated at the corners, the protection of the corners is particularly important. Be careful when using the damaged heat soaked tempered glass when the corners cannot be handled.
2. Avoid keeping the heat soaked tempered glass under pressure for a long time: For the sake of indoor beauty, many families choose to use heat soaked tempered glass as a coffee table for the desktop. Generally, the pressure of heat soaked tempered glass is between 70mpa and 100mpa. The pressure multiplied by the force area of the glass is The higher pressure it can withstand.
3. Keep away from acid and alkali substances: Avoid letting the heat soaked tempered glass come into contact with alkaline substances such as sodium hydroxide (NaOH caustic soda) and hydrofluoric acid (HF). The glass is essentially silicon dioxide (SiO2), which will cause chemical reactions with the above substances. ,
