Abstract

The invention discloses a manufacturing technology for an ultrathin glass protective film. The technology comprises the following steps: (3) using a thinning solution for only one time; (4) airing the product for 4-6min for cleaning the product again; (6) cleaning the product before tempering under the cleaning condition of detergent concentration of 5%, temperature at 50-60 DEG C, cleaning for 3min and drying for 3min that is convenient for subsequent tempering, wherein the thickness of the tempering in the step (6) is 0.05MM; (8) checking the finished products and then performing spot check on the products, thereby increasing the yield of the products. The glass protective film manufactured according to the manufacturing technology is thinner, can be perfectly fit with the present electronic products, has no step feeling in the use process and can guarantee the beautiful appearance of the electronic products.

Description

technical field [0001] The invention belongs to the technical field of glass processing, and more specifically, the invention relates to a production and manufacturing process of an ultra-thin glass protective film. Background technique [0002] With the gradual popularization of existing electronic touch products, more and more smart phones and tablet computers appear in people's lives. But there is a hidden danger in these electronic products, that is, the screen is scratched. Although the touch screens of these electronic products are made of tempered glass with a hardness of 7H or even 7.5H, some careless steps in daily life can scratch the surface of the product, resulting in damage to the appearance of the product, which is even more serious It can even cause the product screen to be broken directly. Along with these problems, screen protectors have appeared in people's lives. A thin PE protective film is attached to the surface of the touch screen, which can preven...
