Vacuum tank (vacuum bag)
A vacuum tank or vacuum bag is a tool designed to create and maintain low pressure or vacuum inside. The concept of vacuum means the complete removal of air from a certain environment, resulting in a very low pressure. In the vacuum formation process, the main goal is to reduce the maximum air pressure inside the tank. However, due to the collision of air molecules with the walls of the tank, some of these molecules still remain inside; Therefore, their number never reaches zero.
These tanks are usually used to maintain vacuum conditions. The concept of vacuum involves the reduction of pressure and the removal of gases from a space that is generally filled with air. Therefore, the main purpose of these reservoirs is to provide an atmosphere under pressure less than the earth’s atmosphere. To achieve this goal, strong and anti-penetration materials are usually used in their construction to limit the entry of air inside and maintain vacuum conditions.
Application of vacuum bag
One of the important applications of vacuum tanks is the bubbling of various liquids such as polyester resin, epoxy and silicone under vacuum conditions. Vacuum tanks have a variety of uses. In physics laboratories, these tanks are used to perform experiments that require low pressure. Also, in various industries such as electronics, they are also used to make and repair air-sensitive parts.
