On November 10, Beijing time, China Touch Screen Network News, DIGITIMES Research Center pointed out that since 2011, the mainland touch panel market has grown rapidly with smart phones, and the size of the tablet device market has also expanded by multiples. Therefore, the mainland touch panel industry has invested in production expansion. It is estimated that the mainland small and medium-sized touch panel shipments will be 252 million pieces in 2010, and will grow to 433 million pieces by 2013. Guanpin Chemical, a well-known manufacturer of special materials in Taiwan, recently released touch glass cutting materials to manufacturers in Futian Industrial Zone, Shenzhen. According to the manufacturers in mainland China, there are still technical bottlenecks in touch glass production in mainland China to be solved by new materials. This time, we benefited a lot from the Guanpin Chemical Technology Seminar.

The implementation of industrial environmental protection regulations in mainland China will be increasingly strict

The bottle neck problem of touch glass mentioned by the manufacturer is firstly environmental protection and safety regulations. In recent years, local governments in mainland China attach great importance to industrial environmental protection issues. All process emissions with serious emissions and heavy pollution are subject to strict supervision, and the penalty can be repeated to order the factory to shut down. In the past, manufacturers used UV hardening strippable adhesive to protect the surface integrity of glass in the cutting process, but after that, they need to soak and strip it with NaOH strong alkaline solution. Now, if there is no sewage treatment and discharge plant, it will face a problem. Therefore, Guanpin Chemical provides the manufacturer with a new U2 UV curing surface protection ink, which has good water resistance and scratch resistance. A good protective film can be formed by screen printing coating and UV light curing, which can avoid damaging the precise glass surface during the cutting process. After the cutting process is completed, soak and peel it with Na2CO3 sodium carbonate weak alkaline solution. This UV curable glass cutting protection ink has attracted great attention. In addition to solving the environmental protection problems in the manufacturing process, it is also very suitable for the stacked glass cutting developed by mainland manufacturers in large-scale production.

Solve the problem of ITO touch glass cleaning

In addition, the manufacturer is faced with the cutting of ITO touch glass. The cutting protection ink used at this stage is too sticky. When cleaning after the event, if the solvent concentration is too high, the splashed line will be damaged. If the solvent concentration is low, it can not be cleaned, and there is residual ink left, which will affect the output quality and efficiency. Therefore, there is an urgent need for a kind of protective ink that can completely protect the ITO touch glass and clean it quickly and easily. Guanpin D4 glass cutting protection ink is completely environment-friendly, tasteless and non-toxic. It can be cut after being baked at 120 ℃ for 1-3 minutes. After construction, it can be washed with water. With low material cost, simple construction, cheap equipment and easy cleaning, it can be said that it is the most suitable protective ink for touch glass cutting at present. Guanpin has been mass produced and shipped. According to the user's evaluation of Guanpin D4 glass cutting protection ink, they generally believe that the quality is not inferior to Japanese products of the same level, cheaper than Japanese products, and the working hours and equipment are much simpler.

According to the research report of Bo Dewei, a researcher in the Optoelectronic Research Center of the Topology Industry Research Institute, the focus of touch panel technology shifted from Japan to Taiwan and South Korea in the early days, and now it is gradually moving westward towards the mainland. Although some key chemical materials of touch panel, including ITO film and silver glue, are still in the hands of Japanese and American manufacturers, Taiwan and mainland manufacturers have mass production capacity in ITO glass and touch IC. At present, the world's top 10 manufacturers in terms of touch panel shipments, and manufacturers of touch panels on both sides of the Straits, including Yanghua, interface, Shiwei, Chenhong, Huayi Circuit, Xinli Truly, Nanjing Huaruichuan, Shenzhen Shenyue Optoelectronics, have been included in the list, and continue to actively expand production this year. Chen Feng, the general manager of Jin Honghuaye, a material agent in Shenzhen, said that it is not easy for ordinary industry analysts to see the huge potential of the shanzhai machine market. However, suppliers who go deep into this market have found that the yield of glass cutting is related to the cost. As long as there is new material development to reduce costs and simplify the process, mainland manufacturers are more receptive than any other country. Therefore, he is willing to promote the newly developed glass cutting protective ink and UV curable strippable adhesive of Taiwan Guanpin Chemical and immediately send samples to major manufacturers.

Liu Bangqing, associate manager of Guanpin Chemical Business Office, said that Guanpin launched cutting protection ink and UV strippable adhesive for touch glass, which is an extension of special adhesive technology. Taiwan manufacturers are the most important suppliers of smart phones and touch screens in the world. The development of the latest applications of special materials should be the most sensitive instinct of Taiwan manufacturers. The change of materials is often an important factor leading to industrial revolution. Taiwan may not be able to become a leader in the research and development of new materials, but it is absolutely capable of ranking first in application. Guanpin hopes that a variety of high-performance adhesives and paints made with unique technologies are widely used in various industries, resulting in a close relationship like glue and paint.
