What is a purification project?

Cleanroom engineering, also known as dust-free workshops, clean rooms, clean rooms, clean factories, etc. Clean room is the more formal term.

Why is purification engineering necessary? Because dust and bacteria, if the particles are very small, they can float in the air, which may not significantly affect humans, but it can have a great impact on some production processes.

For instance, in the semiconductor industry, when particle sizes reach half the size of integrated circuit nodes, they become destructive particles, impacting the manufacturing of integrated circuits. Consequently, the semiconductor industry has very high requirements for cleanliness.

For example, in the new energy vehicle industry, whether it's lithium iron phosphate batteries or ternary lithium batteries, the cost of laboratory purification needs to be completed in a cleanroom. The car painting process also needs to be done in a cleanroom, which is one of the reasons why repair shops and 4S stores can never achieve the original factory paint standard.
