Reason: the causes of out membrane is more, is often difficult to define, the main reasons are:
Production: due to the reason of the coating process, there may be some in the production of acicular membrane, also called the eye of a needle, sputtering coating process itself is unable to avoid. In addition, because of reasons of the coated glass itself or the equipment cleaning, is also likely to cause membrane, the national standards have corresponding requirements and regulations, our factory products are strictly in accordance with the provisions of the inspection, qualified only after leaving the factory.
Lights off film coating machine transportation: glass after unpacking after handling or cutting, not according to the requirements on glass and any pad or cushion pad between unhappy with uneven, direct contact between the glass, glass and glass in the process of handling or transportation directly at the membrane surface caused by the relative friction film. This fell membrane is commonly dot or clumps of membrane, usable hand or feel or check to the trace of the friction test equipment.
Erosion arc ion plating machine off membrane: glass membrane surface in the cut pile, construction use or cleaning, because of the cross construction or use the incorrect method, makes the glass membrane surface contact to acid and alkali or oxidizing substances, such as the glass membrane pollution corrosion and out at the membrane surface. This off membrane can be found at the scene of the off the membrane surface or corrosive substance of residual traces.
