Company book glue properties.
In order to ensure the binding speed of books, different types of hot melt adhesives should be selected according to different machine speeds. Hot melt adhesives are divided into three types according to the binding speed: low speed binding hot melt adhesives (about 3600 copies/hour), medium speed binding hot melt adhesives (about 8000 copies/hour) and high speed binding hot melt adhesives (about 10000 copies/hour). The opening time and curing time of hot melt adhesive are closely related to the speed of binding. The opening time refers to the time between the hot melt adhesive and the other adhesive after the hot melt adhesive is applied to one adhesive. The opening time indicates that the two bonded objects must be bonded within the specified time, so as to ensure the bond strength. The opening time of the low-speed machine is 15 to 20 seconds, the medium-speed machine is 5 to 10 seconds, and the high-speed machine is 2 to 7 seconds. The curing time of hot melt adhesive refers to that after the cover and book block are bonded within the specified time, they can be turned and pressurized after a certain period of cooling, which is called the curing time. If the hot melt glue has not been cured, shaped and turned or cut, the back of the book will be deformed, and the hot melt glue will stick to the blade during cutting, affecting the quality of the product. When used, it should be reasonably selected according to the length of the conveyor belt, transmission speed, seasonal changes, etc. The curing time of hot melt adhesive is generally 3 to 5 minutes. 2) According to paper classification can be divided into coated paper and general paper with hot melt adhesive. The use of different types of paper, to choose the corresponding hot melt adhesive, because the paper surface finish, permeability, thermal conductivity is different. 3) According to the use of binding is classified into side glue and back glue. The hot melt adhesive used as side adhesive has good fluidity, low viscosity, long opening time and curing time, and high bonding strength. Book side glue requirements to achieve thin and uniform, bond firmly, in order to ensure the quality of the book and cutting requirements. You can't use two kinds of glue wrong. 4) According to the color of the glue classification In addition, if it is the same grade of product, yellow glue is better than white glue (but the manual generally requires the glue to be white). 302 series glue can meet the viscosity, hardness and color.
Focus on smart new application Lite to create unlimited possibilities
For many years, Lite-On has cultivated the infrared LED and automotive market. With the progress of LED technology, the penetration of market demand and the expansion of applications, we actively cooperate with customers to develop products, strengthen product lines, and grow with customers. At the 2017 Taiwan International Lighting Technology Exhibition and LED Process Exhibition, Lite-On takes the "creative possibilities" as the main axis, focusing on smart new applications in smart homes and home appliances, automotive smart lighting, mobile and wearable devices, Internet of Things and power management. Rich and complete LED and smart sensor products and related solutions in four major application areas. The author has the opportunity to interview Su Jinhong, Senior Director of the Global Marketing Department and New Product Division of Guangbao Technology Optoelectronics Group, to share the business and future strategies of Lite-On. Theme 1: In-vehicle situation lighting in the automotive lighting market Su Yuhong said that he will benefit from the automotive market demand and product line development. In 2017, vehicle lighting revenue will be significantly improved. In terms of interior lighting, situational lighting has become a trend of high-end car differentiated products. Lite-On has introduced a variety of color temperature situation lighting products. In response to different models of vehicles and panel design, we have selected optimized products for customers. In such a large number of color temperature products, product management and customer cooperation have become the most important key elements to enter this market. Ambient light sensing products can also be combined with automotive panels to automatically adjust the brightness that is best for the driver. At the same time, the infrared emitting component is mainly used for face recognition, and the driver's driving state is detected to provide a warning. The taillights series has a new style and unique LED taillights that have become the focus of automotive lighting design. Lite-On PLCC6 G6S series is a silver-free LED with high resistance to vulcanization. It adopts advanced thermal management and packaging technology. The ambient temperature is raised to 110C, and the future will be 125-135C, providing higher reliability and excellent optical performance. Help customers easily meet the needs of innovative design of taillights. The headlight product series Lite-On demonstrates the complete LED application, covering low-power and medium-high power from inside the vehicle to the outside of the vehicle, providing various customized and personalized requirements for the front-mounted lamp market, and gradually adapting the market from medium to high power. The trend of low power replacement, this year's development focus continues to improve the development of medium and high power light sources. Headlights have gradually become the leading representative of the lamp factory, and high-power light sources are also the focus of this exhibition. In response to the design of the DRL linear light source of the lamp manufacturer, Lite-On introduced a dual crystal to five crystal package with secondary optical design to meet customer needs. In the low beam market, Lite-On's innovative "polycrystalline package LED", each chip can be driven independently, with high reliability, high light efficiency, high color uniformity, high color temperature consistency and low thermal resistance, in addition to In addition to the brightness performance of the international light source factory, the most special is that the current multi-chip package has reserved channels for individual light source control. The diverse and flexible product portfolio is suitable for headlamp applications such as daytime running lights, fog lights, and far and near light, as well as diversified design requirements such as Matrix Beam and Adaptive Driving. Beam, ADB) and so on.
