Scope of application
Automatic
On-Line (shaft wheel type) AP plasma equipment is mainly used in the
electronic industry for mobile phone shell printing, coating, dispensing
and other pre-processing, surface treatment of mobile phone screens;
surface cleaning of electrical connectors; screen printing in general
industries , Transfer printing pre-processing, etc.
Plasma processing
system technology has promoted the rapid development trend of
semiconductor materials and optical industry production, and is widely
used in many high-tech industries such as precision machinery and
equipment, automobile industry, new energy technology, aerospace and
pollution control. The key to the plasma cleaning process of the plasma
treatment system is the use of low-temperature plasma. The key to
low-temperature plasma is caused by external conditions such as high
temperature, high frequency, and high energy. It is a gaseous substance
with neutral, high-energy, and ionized gas. The kinetic energy of
low-temperature plasma is about tens of electron volts, and it contains
ions, electrons, free radicals, and other specific active particles, as
well as ultraviolet rays and other substances. This kind of particles
can easily react with the molecular structure of pollutants on the
surface of the material. It separates out, so it can be cleaned up.
Because the energy of low-temperature plasma is much lower than that of
high-energy rays, this method only involves the surface layer of the raw
material and does not easily affect the properties of the material.
The
automatic plasma equipment is a dry processing technology that uses
electrocatalytic reactions to provide a low-temperature environment, and
also eliminates harmful substances and waste water formed in the
chemical water treatment process. It is safe and reliable, and is
beneficial to environmental protection. Plasma cleaning combines plasma
physics, plasma chemistry and material surface phase reflection, which
can effectively eliminate residual organic air pollutants on the surface
of the material, ensuring that it will not be affected by the surface
and its own characteristics. At this stage, it has replaced the
traditional wet method. Replacement method for cleaning up.
The
automatic plasma equipment technology mainly uses the plasma effect to
act on the surface of the material, causing a series of physical and
chemical reactions, using special active particles and high-energy rays
to reflect and collide with the molecular structure of organic chemical
air pollutants on the surface. Produce small molecules of volatile
substances, which are removed from the surface to achieve a cleaning
effect. It can be seen that plasma cleaning technology has the
advantages of simple process, high efficiency, environmental protection
and energy saving, and environmental protection and pollution-free.
According
to different reaction types, automatic plasma equipment can be divided
into two categories: plasma physics cleaning, which uses special active
particles and high-energy rays to bombard to separate pollutants; plasma
chemical treatment, which uses active particles and residue molecules
to react to separate pollutants Things.
Unlike traditional solution
cleaning, plasma uses the "active effect" of the higher-energy chemicals
contained in it to clean the surface of the material. The actual
cleaning effect is significant, which is a peel-off cleaning. Its
removal effect is specifically manifested in the following aspects:
It
can solve a variety of materials, and has low requirements for cleaning
goals, so it is very suitable for materials that are not resistant to
high temperatures and solvent-based materials;
After cleaning, there
is no need for dryness or other processes, no waste water, no gas
pollution during work, and environmental protection safety;
The
actual operation is simple and easy to control. The vacuum cleaner does
not require a high vacuum value. An atmospheric plasma cleaning process
can also be used. In addition, it can prevent the use of a lot of
solvents, so the cost is low.
Automatic plasma equipment, regardless
of the material type of the target to be processed, has an effective
processing effect on semiconductor materials, metal materials and most
polymers, and can maintain the overall, partial and complex structure
cleaning. The cleaning process can be automated and intelligent, and a
high-precision control system can be installed to accurately control the
time. In addition, plasma cleaning technology is widely used in the
fields of electronic appliances, surface modification materials and
active materials due to its simple use, high precision, and strong
predictability.
Can the difficult bonding problem of medical ePTFE membrane be solved with a plasma cleaner?
In
the actual production and application of medical ePTFE film, it is
inevitable to encounter the problem of difficult bonding. Why is this
product difficult to bond? Can the problem of using plasma cleaning
machines be effectively solved?
Medical ePTFE membrane is a new type
of polymer material, which is made of polytetrafluoroethylene resin
through expansion and stretching processes, so it is also called
expanded polytetrafluoroethylene membrane. Like other PTFE materials,
medical ePTFE membranes also have some bonding problems during the
bonding process. So why is it difficult to bond medical ePTFE membranes?
Can't be solved with plasma cleaning machine?
Due to its excellent
performance, PTFE medical films are widely used in biomedical fields
such as artificial blood vessels and heart patches. But for the bonding
of expanded polytetrafluoroethylene ePTFE, everyone should have a
headache. First of all, we must understand the reasons for the difficult
bonding of medical ePTFE membranes.
Reasons for difficult adhesion of medical ePTFE film:
The
medical expanded polytetrafluoroethylene ePTFE film is generally 4-12mm
thick and needs to meet different practical requirements, so it is
usually laminated with different thicknesses of film layers, or bonded
with other medical materials to form a certain Thickness of the sheet.
Moreover, the bonding effect will be affected by factors such as
material characteristics, adhesive composition, temperature, etc., and
usually cannot meet the bonding and use requirements, that is, the
phenomenon of difficult bonding. The phenomenon of difficulty in bonding
is mainly caused by the following reasons:
1. It is difficult to bond between ePTFE membranes, and the use of complex adhesives will cause damage to the product;
2.
The microporous structure of ePTFE membrane is formed by stretching
under heating conditions. When the temperature reaches a certain level,
the micropores will shrink or even disappear;
3. When the temperature rises, the ineffective components in the chemical binder will be removed.
Regarding
whether the plasma cleaning machine can solve the adhesion problem of
the ePTFE membrane, after repeated experiments and tests, the plasma
cleaning machine can process the ePTFE membrane by selecting a
non-reactive gas. In addition to effectively improving the adhesion of
the ePTFE membrane, it also has other functions. Some processing
advantages will be described in detail in the next article.
