They are used in various applications such as preserving meat and fish in the food industry and for preservation and insect resistance in wood processing. The mechanism consists of three basic elements: the injection nozzle, pressure source, and brine tank. The injection nozzle, typically made of metal, injects the saltwater, while the pressure source, usually compressed air or hydraulic pressure, supplies the saltwater. The brine tank, usually made of metal, stores the saltwater. The key feature is the ability to allow saltwater to penetrate the interior of food or wood, enhancing preservation and anti-corrosion effects.

What Is a Blast Nozzle?

A blast nozzle is a specialized tool used for directing abrasive materials against a surface to clean, improve texture, or modify its appearance. It is essential in surface treatment processes for a variety of materials, including metals, plastics, and wood.

There are two main types of blast nozzles: rotary and linear. Rotary nozzles are preferred for their ability to provide comprehensive and uniform surface treatment over larger areas, making them ideal for tasks requiring consistent polishing or surface preparation. Linear nozzles, on the other hand, are designed for precision work, allowing for targeted treatment of narrow or confined spaces.

The operational mechanism of a blast nozzle involves a combination of three key components: the nozzle itself, which is usually constructed from durable metals to withstand the abrasive action; the air jet, which delivers compressed air or gas to propel the abrasive material through the nozzle; and the abrasive material, such as alumina, steel grit, or glass beads, used to achieve the desired surface finish. Together, these elements enable the effective treatment of surfaces for purposes such as paint removal, rust elimination, and creating a finished texture on various materials.

What Is a Barrier Chain?

A barrier chain is a versatile safety device used primarily to demarcate hazardous areas and protect workers in industrial environments. By creating a physical barrier around dangerous machinery or equipment, it plays a crucial role in enhancing workplace safety.
