Bayer newly develops polyurethane coatings for mobile phones

(Summary description)People are using handheld electronic devices such as mobile phones, MP3 music players, and laptop computers. Because their hands are relatively sticky and sometimes greasy, the surface paint layer of these devices will wear out over a long period of time. In order to prevent this phenomenon, Bayer MaterialScience has developed a new type of radiation-curable polyurethane dispersion, which is coated on the surface of these products, so that they can maintain their new appearance for a long time.

Information

  People are using handheld electronic devices such as mobile phones, MP3 music players, and laptop computers. Because their hands are relatively sticky and sometimes greasy, the surface paint layer of these devices will wear out over a long period of time. In order to prevent this phenomenon, Bayer MaterialScience has developed a new type of radiation-curable polyurethane dispersion, which is coated on the surface of these products, so that they can maintain their new appearance for a long time.

  Dr. Jan Weikard, one of the developers of this product, introduced that Bayer has successfully developed Bayhydrol UV series products for the coating of wood and furniture. Because this material is water-based and does not contain solvents, it is conducive to environmental protection and recycling. It saves costs, so it is more and more popular in the wood and furniture fields, and its development is especially rapid. The radiation curing technology has enabled Bayer to replicate the success of Bayhydrol UV and bring a series of expanded new uses. Among them, the high-end application that has made breakthroughs is Bayhydrol UV XP 2689, which is the aforementioned handheld electronic device coating. Ultraviolet radiation, the molecular structure of the material becomes highly cross-linked, which can produce great hydrolysis resistance, and can also resist the corrosion of cosmetics." In addition, this new product can give a strong, scratch-resistant and tear-resistant The coating is painted again to remove the roughness and make the final surface extremely smooth.

  Another Bayhydrol UV XP 2736 product is also superior in performance. As an adhesive for plastic films and fabrics, it can make the finished product have strong adhesion and mechanical resistance. When Bayhydrol UV XP 2736 is used with other UV-curable dispersions, it can also improve the ultimate elasticity and flexibility of the coating.

Chapter 4 The correct use of rice hulling rubber rollers

The shelling process of cereal grains generally goes through three basic steps: squeezing, rubbing and tearing, and peeling. Among them, rubbing and tearing are the key to peeling. The size of rubbing and tearing depends on two important factors: one is the friction, and the friction The size depends on the pressure between the two rollers; the second is the length of the relative action time of this reverse friction force on the grain, and the length of this action time depends on the relative speed of the two rollers, which is related to the difference in linear velocity. . It is not difficult to see that the pressure between the rollers and the linear speed difference are important process parameters for rice hulling. The correct selection of it not only directly affects the hulling rate, but also affects the consumption of rubber rollers.

Chapter 2 The basic characteristics and performance of the rice hulling rubber roller

At present, there are three types of rice hulling rubber rollers in my country and internationally, which are also called three series, respectively named: wheel type, sleeve type, and build type. Wheel type: Positioning by the center flange hole, 3 or 4 bolt holes are fixed on the two main shafts of the hulling machine.

Chapter One Introduction to Rice Husking Cots

Since the rubber roller hulling machine replaced the sand plate hulling machine and the iron roller rice milling machine, it became the special equipment for rice hulling in the rice milling industry. With its large output, high hulling rate, low rice breaking rate, and power It is widely used by rice processing plants because of its advantages of low consumption and convenient operation.
