  With the development of material technology and core processing technology, the problem of amorphous alloy core processing is gradually solved. Using amorphous alloy materials to replace silicon steel sheet materials to manufacture transformer cores, the no-load loss of the transformer can be reduced by nearly 70%. However, because the manufacturing process of the motor core is more complex than that of the transformer, and the   amorphous alloy material   has the shortcomings of thin ribbon, high hardness, and brittleness after annealing, it is difficult to directly apply the traditional stamping process to the manufacture of amorphous alloy motor core with the help of direct spray ribbons, the performance advantages of amorphous alloy cores have been highlighted. Due to the superior low loss density characteristics of the amorphous alloy material, the loss caused by the carrier harmonics of the inverter power supply in the amorphous alloy motor stator core is still lower than that

  Tacky Rollers   are designed to remove particulate from flat and slightly textured surfaces within the cleanroom including floors, ceilings, and walls.   A tacky roller is exactly like a lint roller but looks more like a paint roller. Instead of rolling paint onto the wall, the rolling part features sticky polyethylene film sheets. When the tacky film is rolled over a surface, it grabs any loose matter, creating a particle free surface. Once the sheet is contaminated and no-longer tacky, it’s time to tear it off and expose a new layer. It’s a quick, clean, and cost-effective way to remove difficult particles from flat surfaces such as walls, tables, and windows. Sticky rollers  are composed of polyethylene sheets coated with acrylic-based adhesive, which can be fast, efficient and easy to remove dust and particle. The standard core diameter sizes are designed to allow maximum effectively clean wide or narrow areas with less frequent sheet disposal. Particulates are limited by the lif
