The electrostatic fault screen printing screen printing screen printing machine

Static current generally small, the potential difference is very big, can appear along with all the attraction, exclusion, conductive, such as discharge phenomenon.

     (1) to the ill effects of silk screen printing.Of silk screen printing, for scraping board rubber pressure make the rubber part and screen charge.Screen itself charged, can affect the normal weight, produce wall failure,At the instant of the substrates and output will be silk screen.

A. when printing plus hotline glass is charged.

B. make the glass surface easily electrostatic adsorption ink particles, the glass surface is not clean.

C. the body electric shock caused by static electricity, was due to the contact of a charged object, or savings before the electrostatic spark discharge during grounding on.Shock current is small, not dangerous, but frequent shock, can bring bad influence to the operating personnel's psychological.

    (2) to prevent electrostatic method.Prevent electrostatic generation methods are: adjust the environment temperature, increase the air humidity, appropriate temperature is 20 ℃ or so commonly, relative humidity 60%;Can make the static electricity which is passed in wet air;Decrease network distance and reduce the printing speed.
