Everything has a dual nature, the same understanding of the advantages of plasma cleaning technology at the same time, but also should understand its shortcomings, and the use of the problems, plasma cleaning in the application there are some constraints, mainly in the next few points :
has a dual nature, the same understanding of the advantages of plasma
cleaning technology at the same time, but also should understand its
shortcomings, and the use of the problems, plasma cleaning in the
application there are some constraints, mainly in the next few points :
1. This method can not be used to remove the surface of the object of
the cutting powder, which in the cleaning of metal surface grease when
the performance is particularly evident.
Practice has proved that it can not use it very thick oil, although the
plasma cleaning a small amount attached to the surface of the oil
surface has a very good effect, but the removal of thick grease is often
poor, on the one hand with it to remove the oil film, must To
extend the processing time, so that the cost of cleaning greatly
improved, on the other hand it is possible in the process of contact
with thick grease in the process, triggering oil molecules in the
molecular structure of the unsaturated bond polymerization, coupling and
other complex reactions and the formation of hard Of the resin-like three-dimensional network structure. Once the formation of such resin film he will be difficult to be cleared. So usually only the plasma cleaning thickness of several microns in the following oil.
In the application process also found that the plasma cleaning can not
be used to remove the surface adhesion of fingerprints, and fingerprints
of glass optical components often appear on a pollutant. Plasma
cleaning is not completely out of the fingerprint, but it needs to
extend the processing time, then they have to take into account that
this will be the performance of the substrate will cause adverse
effects. So it is necessary to use other cleaning measures for pre-treatment match. As a result, the cleaning process is complicated.
Since the plasma cleaning process requires a vacuum treatment and is
generally on-line for online or batch production, the problem of storage
and transfer of the workpiece to be cleaned must be taken into account
when introducing the plasma cleaning device into the production line, Deal with the larger volume of the workpiece, the number should be more consideration to this problem.
summary, the plasma cleaning technology is suitable for the surface of
the oil, water and particles and other mild oil cleaning, and conducive
to "quick" online or batch cleaning.
