Description
[technical field]
The present invention relates to a kind of film anti-static liquids, in particular to film anti-static liquid and its antistatic film system
Preparation Method.
[background technique]
Automatic assembly line production process can usually use manipulator, and plurality of positions, which has, in manipulator uses drag chain knot
In ceaselessly operation, the drag chain of manipulator is connected for structure, drag chain, manipulator in structural establishment and the drag chain connecting with manipulator
Wire and cable also follow drag chain ceaselessly move back and forth, wire and cable prolonged operation movement will lead to wire and cable
Rubber ruptures it could even be possible to making its fracture.Since drag chain, manipulator and the drag chain connecting with manipulator are being made for a long time
Also a large amount of dust, electrostatic can be generated in industry, and for precise electronic, dust and electrostatic are the jinxs of electronic product, for that can keep away
Exempt from a large amount of dusts and electrostatic that drag chain, manipulator and the wire and cable being connect on drag chain with manipulator are generated in operation process.
Would generally use at present film by drag chain, manipulator and connect with manipulator drag chain wire and cable wrap up it is quiet to reduce
Electricity and dust, in order to protect the wire and cable on drag chain, traditional way is to wrap up a protective layer in the external of wire and cable,
Use plastic film usually to encase the wire and cable on drag chain to be protected.However plastic film is usually PU material system
Make, the generation of electrostatic cannot be prevented well, the wire and cable on drag chain is wrapped up by plastic film and is still also had largely
Electrostatic generates.If the surface electrostatic of film is very big in use using without the film Jing Guo antistatic process,
The big film surface of static content will assemble very more dusts, electrostatic and dust for requiring the product of production environment harshness will
Directly affect the quality of product or there are product quality hidden danger, in addition, electrostatic be also for the damage of electronic product greatly it is especially big,
Directly electronic component can be burnt or be punctured.Film without antistatic process is not to be able to satisfy production environment harshness
The production requirement of automatic assembly line.
For presently, there are the technical issues of, be badly in need of developing the protective film of the high wire and cable of a antistatic performance
To substitute conventional films.
