Whether the low temperature plasma treatment time is as long as possible
Not necessarily. The cross-linking, chemical modification and etching of the surface of the polymer treated by low-temperature plasma are mainly caused by the plasma breaking the bond of the surface molecules of the polymer to generate a large amount of free radicals. Experiments show that as the plasma treatment time increases and the discharge power increases, the generated free radical strength increases. After reaching the maximum point, it enters a dynamic equilibrium. When the discharge pressure is at a certain value, the free radical strength appears to be the maximum, that is, Low temperature plasma reacts to the surface of the polymer to the fullest extent under certain conditions
Therefore, low temperature plasma surface treatment has a most reasonable time, which can achieve the best treatment effect, increase production efficiency and reduce equipment use cost.

What do you need for low temperature plasma equipment?
Low-temperature plasma equipment unit power is about 1000W, only need clean compressed air, power supply 220V/380V, and exhaust gas exhaust device
——Exhaust gas device is designed to reduce the noise of exhaust gas and avoid the occurrence of similar smoke in the exhaust gas.
.
How much can the production line speed reach?
Because of different material types,
Different sizes,
Different processes and different acceptance criteria,
Different devices handle different products at different speeds
.
Experience in different industries is
For the bonding of the mobile phone keys and the mobile phone case, the maximum line speed of the surface treatment is 6 m/min or more; for the sealing strip, the maximum surface speed of the surface treatment is 18 m/min or more; for the flocking front surface of the sealing strip Handle the maximum line speed to 8 meters / min or more;
The effect that a specific product can achieve is obtained through trial and error. Customers in Sichuan, Chongqing and Guangdong can provide free testing before sale.
.
Can low temperature plasma processing remove the primer?
Can't answer clearly. However, we are in many areas, such as
Bonding, painting, flocking, pad printing
,
Coding
And other successful applications that use plasma surface treatment to eliminate primers
.
How long does the added surface energy remain after low temperature plasma treatment?
Because of the nature of the material itself,
Storage environment,
After treatment, it is subject to secondary pollution, chemical reaction, etc., and the surface can be retained after treatment.
Unable
determine. We recommend that after low-temperature plasma treatment to achieve higher surface energy, proceed to the next step to avoid the effects of surface energy attenuation.
Our company can perfectly integrate low temperature plasma processing equipment into the automated production line to eliminate the possibility of secondary pollution.
.
Can a low temperature plasma surface treatment system be used online?
Yes, and, very easy
. Whether it is cell phone key bonding, case coating, flocking of sealing strips, sealing strip spraying or other, the online use of low temperature plasma surface treatment systems has become a reality. We can also match the system to the production line according to the specific requirements of the unit production line, whether it is a new line or an old line transformation.
Whether the low temperature plasma treatment process will cause pollution
Low-temperature plasma surface treatment is a “clean†treatment process. Only a small amount of ozone O3 is produced during the treatment process due to ionized air. However, some materials will decompose a small amount of nitrogen oxides during processing, and should be equipped with an exhaust system.
Specifically, you can refer to the instructions provided by our company, all instructions on equipment layout and use.
.
Does special plasma require low temperature plasma treatment?
In addition to compressed air during on-line processing, no special gases are required. However, if it is a glow discharge device under sub-atmospheric pressure, it may be filled with an inert gas such as argon gas or helium gas, and subjected to surface treatment under an atmosphere different from air.
Vacuum plasma treatment mainly uses five kinds of gases: hydrogen, oxygen, nitrogen, argon, carbon tetrafluoride.
Is it dangerous to use low temperature plasma equipment?
Low-temperature plasma equipment works in a high-pressure environment, but the equipment is always the most important standard in the design, production and use, and the current is very low. Inadvertent contact with the plasma discharge area will create a "acupuncture" sensation, but there will be no crisis in personal safety. We usually shield the discharge area and physically isolate it.
Can a low temperature plasma system handle complex three-dimensional surfaces such as grooves?
Whether for complex three-dimensional surfaces such as sheets, grooves, holes, rings, etc., we are able to provide a corresponding low temperature plasma surface treatment system.
Does low temperature plasma treatment change the nature of the material itself?
Low temperature plasma surface treatment only treats the surface of the Amy-micron material, the properties of the material
Basic
No effect
The naked eye can't completely distinguish whether the material has undergone plasma treatment.
