How to choose glass film, try not to choose low-priced goods



Many friends have appeared in the glass film after the purchase of the tempered glass film automatically fragmented, in fact, this is well understood, tempered glass film is also a glass, so broken is also a normal thing.

 

 The decision to break the glass film breaks into two categories. One is the problem of the product itself and the second is the problem of use. From the product itself, whether or not the tempered glass film is fragile is analyzed from raw materials and processes.

   

1, raw materials. Glass films are made from different brands of glass raw materials. The strength of different raw materials will be different. However, unless it is a glass raw material that is itself defective, most glass manufacturers have little difference in terms of strength glass.

 

 2, processing technology. There are three main processes that determine the quality of finished glass films: CNC cutting, edge polishing, and tempering furnace tempering. CNC cutting is cutting the glass material into a shape that fits the phone model. The edge polishing is to polish the edge of the straight edge tempered film into a 2.5D arc edge. The tempering furnace tempering is to let the semi-finished glass film in the high-temperature furnace and potassium nitrate role to make the glass film strength slightly increase the strength, greatly increase the toughness, to ensure even if the glass film is broken, it will not harm the human body.

 

  Regardless of the bonding of the glass film adhesive, these three processes are the three processes that are most likely to occur in defective glass products. Cutting and polishing may cause the glass to burst. The tempering time of the tempering furnace is not enough, and the poor use of potassium nitrate will cause the strength and toughness to decrease. Most of the defective products were eliminated during the production process, and a small number of defective products could not be detected by the naked eye. Tramples and trachoma were left as good products to enter the market. Fragmentation occurred when they were used a little. Therefore, when everyone decides to purchase a tempered film, it must be remembered that you do not choose those low-price goods in the market. The principle of a penny-and-delivery product is universal.

 

  In addition, the thickness and strength of tempered glass film also have a certain relationship, simply in terms of strength, the thick glass film is slightly stronger, the thinner the glass film strength is, but the thinner the glass film feel is, the better, everyone is choosing When tempered film is also based on their own circumstances.
