Common causes of rupture of PE stretch film

图片
  PE stretch film   is currently the largest rated packaging and transportation protection product in sales. It is inevitable that the PE stretch film will break. There are many factors that affect the stretch film. Stretch film is possible in the production process from casting to winding. It will cause damage to the stretched film. Although this phenomenon is common, it is more common for stretched films with relatively low thickness. Common causes of PE stretch film breakage: 1. When the stretched film is produced at high speed, ink is stuck on both sides of the printing axis or the printing axis is uneven, and the stretched film is printed on the plate, and unevenness occurs after printing. 2. The production conditions have changed significantly during the casting or longitudinal stretching process, such as the longitudinal thickness of the stretched film changes greatly or the casting sheet has large defects, which causes the casting to be partially stretched during the s...

How to distinguish the quality of PVC electrical wire film?

图片
  PVC electrical wire film  is also called PVC wire wrap film. It is a brand-new packaging material. Its material is ultra-thin, tough, self-adhesive, and resistant to low temperatures. It is an ideal packaging material, often used for wires. In addition, PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives in actual use. They have non-flammability, high strength, weather resistance and excellent geometry. Stability etc. Generally speaking, high-quality  PVC electrical wire film  has the following characteristics: relying on the adsorption effect of static electricity, it has better weather resistance and viscosity stability, after a few days or peeling and then using the strength increase is not obvious, easy to peel off, and There is no residual glue on the protected surface when it is removed. It is not easy to break, but also needs to have good puncture resistance, which can ensure ou...

introduction of CNC Pneumatic Chuck

图片
CNC Pneumatic Chuck  is a mechanical device used to tighten the workpiece on the machine tool. It uses the radial movement of movable jaws evenly distributed on the chuck body to clamp the workpiece and position the machine tool accessories. The CNC Pneumatic Chuck is generally composed of a chuck body, a movable jaw and a jaw drive mechanism. There is a through hole in the center to facilitate the passage of workpieces or bars. The back has a cylindrical or short cone structure, directly or through a flange. The disc is connected to the end of the machine tool spindle. Performance advantages of CNC Pneumatic Chucks: Compared with the manual chuck, the CNC Pneumatic Chuck can automatically center and clamp the workpiece instantly by pressing the button, and the clamping force is stable and adjustable.

Causes of smoke from stretch wrapping film

图片
In today’s society,  stretch wrapping  film  is commonly used in many of our packaging industries and logistics industries. In order to increase the quality of stretch film products for packaging, we need to pay special attention to some details, such as stretch wrapping  film There is a smoking phenomenon, so what causes this phenomenon? Causes of smoke from the stretch wrapping  film: In the production process of stretch film, the main raw material selected is polypropylene, which is a kind of thermoplastic resin polymerized by polypropylene. The working principle of the baler is to instantaneously heat to melt and bond. A long heat dissipation fan accumulates a lot of ash, so it will show smoke during the process of bonding, just like a range hood, if it is used for a long time without wiping and cleaning, the heat dissipation effect will be reduced, and the smoke will be Gradually increase. Therefore, after the stretch film is used for a period of time, be s...

Energy-saving characteristics of moving head light beam

图片
Moving head light beam can be seen everywhere in today's cities, dotted with every city. The beam lights concentrate the light source on a focal point so that the light source can be emitted more concentratedly, forming a light beam. Such lights are called beam lights, or spotlights in layman's terms. Compared with other energy-saving lamps, moving head beam lamps also have their own unique energy-saving features. I will introduce them to you today. Energy-saving features of moving head light  beam : 1. Moving head light beam source has high luminous efficiency Luminous efficiency comparison: incandescent light effect is 10-15lm, halogen tungsten light effect is 12-24 lumens/watt, fluorescent lamp is 50-90 lumens/watt, sodium lamp is 90-140 lumens/watt, most of the power consumption becomes heat loss. Moving head beam lighting effect: it can send 50-200 lumens/watt, and the luminous monochromaticity is good, the spectrum is narrow, and it can directly emit colored visible light...
