The thickness of the first transparent membrane is 12 microns; Its light transmittance is 87% ~ 88%; The glossiness of its 45° angle is 122 gloss unit, and its mist degree is 2.88%; Wetting tension >=the 52mN/m in its sided corona treatment face.
Method and condition and the embodiment 1 of vacuum aluminum-coated processing process are just the same, but the light transmittance being coated with the first transparent membrane of vacuum aluminium coated layer is 2 ± 1%, and final production goes out the adhesive sticker stealth form laminating film that finished product integral light-transmitting rate is 1.5 ± 0.5%.
Obtain stealthy form laminating film by said method to fit through downstream client and face glass, refill to be assigned in the high-grade electric appliance such as refrigerator or air-conditioning and try out, assessment result is: outward appearance is magnificent, the stealthy effect of use safety, form is excellent, touch control instruction fault rate mean value 0.22%, telecommand fault rate mean value 0.26%, does not reach≤the designing requirement of 0.2%; Test 50 pad pasting glass panels, naturally fall in cement flooring from 1.5 meters of eminences are parallel, result of the test: 50 pad pasting glass panels are all cracked, but after only having a pad pasting glass panel ruptures, fragment departs from pad pasting glass body, and the fragment number of disengaging pad pasting glass body is lower than 2; The fragment number departing from pad pasting glass body reaches the safety standard (in 1 pad pasting glass panel) being less than or equal to 5 of designing requirement; Develop glass sheet quality qualification rate >=99.5%, paste curved glass panel quality qualification rate >=99%, be better than >=the designing requirement of 98% and >=95% respectively; But because instruction success rate is below standard, can not instructions for use be met.
