Tempered Glass Protection Film is the last two years of mobile phone protection Film market Novice, since the first mobile phone tempered film products have been listed, has been the industry's attention, with the continuous development of the industry,
Toughened glass film manufacturerIn order to produce better products, the glass material has higher requirements.
For tempered Glass Protective film assembling, its core technical performance in three aspects: AB Double-sided adhesive, tempered glass material itself and processing technology. In addition to the requirements of double-sided adhesive, an ultra-thin tempered glass has a very important position. At present, the pursuit of ultra-thin and gradually rising market for tempered glass membrane manufacturers, is an opportunity and challenges.
For this kind of glass membrane, the most core is AB double-sided adhesive technology. If the colloid itself is not good quality, prone to warping, bubbles, watermarks and other phenomena, and if the glue is too thick, it will affect the light transmittance of the screen display. "In addition to its own quality, its thickness also has a great impact." Now on the market production of special-purpose mobile phone tempered glass generally around 0.4mm, and the production of AB double-sided adhesive thickness specifications generally above 0.12mm. What is this concept? That is, the entire toughened glass film will include tempered glass and two layers of colloid will reach around 0.6mm, which is a considerable thickness. This is not the same as the pursuit of ultra-thin ideas now. ”
Higher requirements for glass materials for tempered glass protective film, its core technology in three aspects: tempered glass material itself, AB double-sided adhesive and processing technology. In addition to the requirements of double-sided adhesive, an ultra-thin tempered glass also has an important position. Nowadays, the pursuit of ultra-thin and gradually rising market for the production of tempered glass enterprises, is an opportunity and challenge. "The use of tempered glass in the field of touch screen is generally made by adding additives to ordinary glass and then processing and grinding thin." The thinner the glass is made, the more likely it is to be damaged, and the cost can be increased. For example, if the thickness of tempered glass is reduced from 0.4mm to 0.2mm, the cost will be 4 times times more than the original. "said Chen Yu Yang. The domestic glass original manufacturing level is also limited, processing level is relatively low, can be called the real brand of enterprises in the domestic has not yet appeared, the general quality of the original film is still from abroad. "Some manufacturers use B-type glass as raw materials, so that the production of tempered glass material is poor, but also affect the performance of ab gum, resulting in the glass film on the touch screen prone to watermark phenomenon. "In addition to the glass material itself and ab double-sided adhesive, tempered glass membrane as a new product, its processing needs to break through." "Now, the overall output of the industry is low, take 0.4mm tempered glass processing as an example, a device one day produced the finished product generally in 500 pieces of ~700 tablets, which for the entire market production technology and level is still very few. "Chen Yu Yang introduced to," causes this kind of problem mainly has two reasons: first, the processing level is not advanced, seriously affects the product quality; second, the processing level deviation also causes the material damage quantity to increase, the qualified product success rate is low, causes the cost the massive waste. ”
In fact, the toughened glass film has been widely used in the European market years ago, and for this reason, its products were mainly supplied to the European market. For the domestic market, tempered glass film from the beginning of this year to mount the stage, the second half into the initial stage of application, but still has not been popularized. For the domestic market, tempered glass protective film is a new product, and its industrial chain is just beginning. Whether it is glass raw materials or ab double-sided adhesive production chain can only be regarded as the primary stage. "For example, although the AB double-sided adhesive produced by our company has been successfully developed and put into production in Japan a few years ago, market-oriented sales, especially in the domestic market, have not really opened until recently," said Chen Yu. It can be imagined that the overall market situation of tempered glass film. "Although the industry chain has not yet been perfected, the market outlook is indeed extremely optimistic. With the development of the touch screen industry, this closely linked with the glass membrane market will be fully opened, the future of mobile phones, tablet computers, navigation systems and other industries will have their needs. "Although the domestic market will become a new growth point for this product, it is premature to realize localization production." Because whether the glass original film processing or the overall level of technology, domestic manufacturers still can not guarantee product quality. "Another aspect, I think, is that although the market is in great demand now, the life cycle is not too long," Chen Yu said. Because there will be more advanced products, and mobile phones, computers and other industries may also be targeted at the screen itself for more high-end research and development, the demand for membrane products will also be reduced. Therefore, in order to develop more, the industry still needs to keep innovating continuously. "My qq/:1139135599, welcome everyone to add to be friends."
