In distribution panels, it is employed in branch circuits of the power supply, while in electrical devices, it is utilized within the internal circuits.

The mechanism of a square fuse comprises an outer casing, fusible element, and contacts. Noteworthy features include high durability, allowing for prolonged use, and easy replacement. Regular checks of the rated current and periodic replacements are crucial, ensuring the safety of the electrical circuit.

What Is a Sonotrode?

A sonotrode is a machine that utilizes ultrasonic waves for cleaning and processing objects.

The ultrasonic generator transmits ultrasonic waves to the cleaning solution through a transducer, employing a mechanism that dislodges dirt and deposits from the surface of objects. Consisting of a transducer, cleaning tank, and heating device, it uses ultrasonic vibrations to agitate the cleaning solution, effectively removing dirt from the surface of objects. It is primarily utilized in the processing of food and the manufacturing of industrial products.

In food processing, it is used for cleaning and sterilizing items such as meat, fish, and vegetables, while in industrial product manufacturing, it plays a role in cleaning and processing metal and plastic components. In the medical field, it finds applications in cleaning and disinfecting medical devices. Its features include high cleaning efficiency, short cleaning times, and environmentally friendly operation.

During use, attention should be given to the selection of the cleaning solution, setting the cleaning time, and ensuring safety through the vibrations generated by ultrasonic waves.

What Is a Sausage Cutter?

A sausage cutter is a machine designed for the purpose of cutting sausages.

It is primarily used in meat processing plants, supermarkets, and restaurants. The sausage is held in place by a sausage holder, and the cutter is activated by blades or rollers to perform the cutting. The operating principles are divided into blade-type and roller-type, where the blade-type provides a clean cutting surface, and the roller-type is cost-effective and offers safe usage. Compared to manual methods, these cutters provide efficient and uniform cutting, with the roller-type particularly known for its safety advantages over blade-type cutters.

In meat processing plants, they are utilized in the manufacturing process, in supermarkets for display and sale, and in restaurants for cooking. During use, it is important to regularly check the condition of blades or rollers, pay attention to the thickness of the sausages, and ensure safe operation.

What Is a Rotating Beacon?

A rotating beacon is a lighting device that attracts visual attention by rotating a light source.

It is primarily used as a warning light or signal light. There are two main types: motor-driven and optical type. The motor-driven type generates powerful rotational force but has a complex structure and is costlier. On the other hand, the optical type is simple, cost-effective, and characterized by low noise.

Rotating beacons are employed on roads, buildings, public facilities, etc., and are utilized by emergency vehicles, construction vehicles, and during emergencies or evacuations. The mechanism consists of a light source, rotating part, and control unit, creating a rotation of the emitted light. The key features include high visibility and warning effectiveness, with the ability to set various rotation patterns from a simple circular motion to complex patterns.

During use, attention should be given to the installation location, orientation, and operating environment. Regular inspections and maintenance are necessary.

What Is a Portable Step Ladder?

A portable step ladder is a convenient ladder that can be easily carried and becomes compact when folded.

It is mainly divided into telescopic and folding types. The telescopic type allows for easy adjustment by extending the legs, while the folding type becomes compact by folding the legs, although it requires a bit more effort to fold.

It finds a wide range of applications such as installing or repairing appliances, pruning trees in the garden, painting exterior walls, camping, and outdoor activities. It is particularly effective for tasks at elevated heights and outdoor use.

The key features include its convenience for transport and the ability to fit into a car, as well as its versatility for various purposes. During use, it is essential to confirm the fixation of each part and the weight-bearing capacity. Usage in unstable locations or abrupt movements should be avoided.

What Is a Polyester Adhesive?

A polyester adhesive is an adhesive with polyester resin as its main component.

Hardening occurs by mixing polyester resin with the curing agent, polyisocyanate. Through this reaction, the polyester resin bonds with the surface of the adherend, creating a robust adhesive strength.

It finds widespread use in automotive components, electrical equipment, construction materials, textiles, and other fields where its characteristics are required. The adhesive mechanism is classified into chemical bonding, mechanical bonding, and penetration bonding, each catering to different applications.

Characterized by heat resistance, chemical resistance, water resistance, high strength, and versatility, polyester adhesive can adapt to various adherends. However, it is important to pay attention to the mixing ratio of the curing agent during use, and sufficient curing time is necessary as the hardening process takes time. Due to its high volatility, adequate ventilation is also required.

What Is a Belt Brush?

A belt brush is a specialized cleaning tool used for product washing and conveying.

This brush comes into contact with the product as the belt rotates, removing dirt and grease while simultaneously transporting the product. The belt-shaped design increases the surface area of the brush, allowing for efficient cleaning and conveying. Adjusting the length and width of the belt enables adaptation to different products or components, making it suitable for various applications. The ability to combine belts and brushes of different materials allows for the creation of belt brushes tailored to specific purposes.
