Painted Glass sought after by the current fashionable young people
With the smart phone continues to progress, colorful mobile phone film has become a young man favorite a mobile phone decoration, and color Painted Glass is undoubtedly the most popular mobile phone favorite young people, its characteristics are super wear and tear resistance , Then how to correctly buy Painted Glass it, Painted Glass manufacturers to teach you the right to buy color Painted Glass method:
1, whether the oil: take a bottle of water to Painted Glass down to see if the condensate of water, if it is scattered on the instructions that no oil; or take the pen to write a little, good color Painted Glass is not left Under the traces of, even if left, and only need to be able to wipe the good;
2, whether the scratch: holding the blade in the Painted Glass on the scratch, if the blade easily in the Painted Glass left traces, do not think, this is certainly not qualified Painted Glass;
3, the surface is lubricated: depends on whether the edge of Painted Glass barbs or irregular, crooked and so on, there are certainly these problems are not qualified Painted Glass, or feel a sticky rough feeling, are unqualified of;
4, whether the explosion: This is a very important thing, if not explosion, when the phone Painted Glass fragments will cut the user's skin, the user's safety caused a danger, and if it is explosion-proof, glass film after fragmentation , There will be no debris, only Painted Glass broken lines, mobile phone screen will not be broken. That in the end how to see if it is explosion? We all know hard things, the better the flexibility, the stronger the ability to fight.
If the nickel sulfide crystals appear in the stress area of the Painted Glass, the blemish will occur as long as the crystal transition occurs. As the crystal transition time is uncertain, at room temperature Painted Glass blew is completely uncertain, detonation treatment to reduce the blew probability is low.
After a strict homogeneous treatment, Painted Glass blew probability will be greatly reduced, every 10,000 square meters of glass in 1 year, the probability of occurrence of a blew only 1%. At this time Painted Glass can be called the real safety glass.
When the nickel sulfide crystal from the α phase, into the β phase, the crystal volume will have 2-4% change, causing Painted Glass bleached nickel sulfide crystal diameter of about 0.2mm or so. Painted Glass The reason for blew is due to the fact that some of the nickel-containing impurities are mixed in the melt of raw materials or refractories during the manufacture of the glass, which are used to form nickel sulfide crystals during glass melting. Nickel sulfide crystal over 380 ℃ high temperature is α phase, room temperature is β phase.
The cooling rate of the glass is very fast under the action of the cooling air. When the glass is cooled to room temperature and the structure is completely fixed, the nickel sulfide crystal is too late to convert to the β phase in the low temperature state and still exist at the high temperature α phase. In the original piece of glass molding, need to go through a slow annealing process, nickel sulfide crystals will not affect the basic strength of the glass. But when the glass for steel processing situation is very different. Because Painted Glass is used in the quenching process.
To solve the painted Glass blew, the Painted Glass is homogenized: the Painted Glass is reheated to 280-300 ° C and then held for 2-4 hours to burst the conditionally bleached Painted Glass in this process. Painted Glass homogenization is also known as Painted Glass's detonation or Painted Glass's hot-dip treatment. If the nickel sulfide crystals appear in the stress area of the Painted Glass, the blemish will occur as long as the crystal transition occurs. As the crystal transition time is uncertain, at room temperature Painted Glass blew is completely uncertain, detonation treatment to reduce the blew probability is low.
