图片
  Usage and maintenance of hot melt glue gun To help employees safely and effectively use a  hot melt glue gun  for production operations, standardize the operation steps of employees, enhance the maintenance and maintenance awareness of employees on tools, pinching hot melt glue machine manufacturer to introduce the use of hot melt glue gun and maintenance. Notes on a hot melt glue gun 1. Before using the hot melt glue gun, please check whether the power supply is energized, whether the bracket is equipped, Whether the used glue gun pushes the glue smoothly. 2. When the hot melt glue gun is used, plug in the power cord and preheat it for about 5 minutes or until the rubber strip is completely melted. Please stand on the table when the glue gun is not in use. 3. After the strip melts, aim the nozzle of the glue gun at the part where the glue is needed and press the trigger gently to let the glue flow out naturally. 4, after using the nozzle downward, unplug the power plug. 5. Do not pu

Hot melt adhesive is more and more widely used in carton packaging

图片
  Hot melt adhesive is more and more widely used in carton packaging As a new type of carton and paper box packaging sealing form,  hot melt adhesive sealing  has replaced the traditional binding packaging and tape packaging, used in the carton packaging of all kinds of food, as well as wine, dairy products and other carton packaging. Because of the advantages of good packaging quality, beautiful appearance and low cost, the application of hot melt adhesive sealing box will be more and more widely. Advantages of hot melt adhesive sealing Hot melt adhesive box sealing is to use the hot melt machine to melt the hot melt adhesive into liquid, and then through the hot melt machine throat and gun, sent to the surface of the carton, hot melt adhesive cooling is completed after bonding. It can meet the requirements of carton sealing, and overcome the defects of the traditional carton sealing form. Good packing quality Transport cartons must be able to withstand changes in temperature, humidit

Effect of plasma surface treatment on surface modification

图片
  Effect of plasma surface treatment on surface modification Plasma surface treatment  is to etch the surface and generate free radicals, but when the material contacts the air, the free radicals on the surface will continue to react with the active gas in the air and generate polar groups. The type of gas plays a decisive role in the state of the plasma, and it directly affects the modification method and result of the surface of the polymer material by the plasma. Plasma surface treatment generally uses non-polymeric gases, including non-reactive gases and reactive gases. Non-reactive gases refer to inert gases such as He and Ar. When the plasma of this type of gas acts on the material, the inert gas originates from and does not combine with the polymer chain. Plasma surface treatment is to etch the surface and generate free radicals. , But when the material contacts the air, the free radicals on the surface will continue to react with the active gas in the air to produce polar group

Plasma surface treatment equipment is used in display

图片
  Plasma surface treatment equipment is used in display In the electronics industry, the  plasma surface treatment equipment  is a key technology that can achieve cost-effective and reliable processes. Before printing a conductive coating on a printed circuit board, plasma activation treatment, fine cleaning of plasma surface treatment equipment and electrostatic removal treatment are carried out. It can ensure that the coating is firmly attached, and the use of surface plasma cleaning technology in the field of chip packaging eliminates the need for a vacuum chamber. Plasma surface treatment equipment must first perform plasma treatment on the plastic window part. Due to the use of plasma technology, the surface performance of the material is improved, so the coating distribution is more uniform, which not only creates an impeccable product appearance, but also greatly reduces the production process. Rejection rate. Application of plasma treatment equipment in FPC circuit board indust

How to choose high quality plasma surface treatment machine manufacturers？

图片
  The   plasma surface treatment machine   uses plasma to achieve effects that conventional cleaning methods cannot achieve. Plasma is a state of matter, also called the fourth state of matter, and it is not the standard three states of solid, liquid and gas. The plasma surface treatment machine uses the properties of these active components to treat the surface of the sample to achieve cleaning, coating and other purposes. How to treat the plasma surface treatment machine?  Common plasma surface treatment effects use contact angle measuring instruments, dyne pens, and surface energy test inks. The contact angle measuring instrument is currently the most common and industry-recognized testing method for evaluating the effect of plasma surface treatment machines. The test data is accurate, the operation is simple and convenient, the repeatability and stability are high. The principle is to titrate a certain amount of droplets on the surface of a solid sample through the method of optica
