【Overview of impregnation】

Impregnation is a technology that immerses liquid into the gaps inside the material.
By placing a material in a processing container (tank) and placing it in a reduced pressure environment, the air bubbles inside are removed, liquid is injected into the tank to impregnate it, and then further pressurized to rapidly penetrate the gaps inside the material.
Various impregnation treatments are used to maintain airtightness and prevent corrosion of metal, wood, and resin, as an insulating layer in motor coils, and in food and electronic components.
The main methods are “vacuum impregnation,” which uses a vacuum to infiltrate liquid, and “vacuum pressure impregnation,” which applies pressure after vacuum impregnation.

【Example of impregnation tank production】

This is a case where electrolyte impregnation is carried out in a pressurized and vacuum tank for condensers, batteries, etc.

( ※ Impregnation tank specifications and line configuration are determined depending on the purpose of use and conditions of the impregnated object. )

There are two types of pressure: “absolute pressure” and “gauge pressure.”
"Absolute pressure" refers to an absolute vacuum (a vacuum in which no atmosphere exists at all) with zero.
In comparison, "gauge pressure" is the pressure measured at zero atmospheric pressure.
"Absolute pressure" is often used to describe a vacuum, while "gauge pressure" is used to describe a degree of pressure.
