The invention relates to an apparatus and process for pre-coating (111) and subsequent digital sol-gel inkjet printing (122) on a metal strip, where then a protective clear coat (124) is applied over the dried ink. The core of the invention lies in the fact that the printing is of the sol-gel ink type and the pre-coating (111) is no longer performed by separate application of two layers of coating, namely a primer and a base coat, and the relative drying and cooling phases of the coatings, but by application of a single coating that combines the functions of the primer and base coat. Furthermore, the process is even further simplified by printing with a special sol-gel ink type that does not require UV treatment, only a simple drying of the ink after application.

The present invention relates to a method for producing beetle oil enriched with vitamin D3, comprising a light treatment step in which at least one light source emits ultraviolet radiation in the direction of said beetle oil.

This invention relates to the field of UV anti-adhesion film preparation technology, specifically to a UV anti-adhesion film for UTG processing with dual crosslinking control and its preparation method. It consists of a modified PO base film and a composite adhesive layer. The modified PO base film is a polyethylene-polypropylene blend modified polyolefin film. The composite adhesive layer contains a fluorinated modified polyurethane acrylate prepolymer, a multifunctional UV monomer, a composite photoinitiator, and a dual interface modifier. The mass percentages of each component are 38-45%, 42-48%, 3-5%, and 2-4%, respectively. The multifunctional UV monomer is a mixture of TMPTA and HDDA at a mass ratio of 1:1.2. This invention optimizes the adhesive layer formulation and base film pretreatment process, improving etch resistance and interfacial compatibility, achieving precise matching of peel force before and after UV treatment, resulting in a product with low thermal shrinkage, minimal adhesive residue, and reduced glass damage. It significantly improves the yield of UTG thinning and is suitable for large-scale processing of flexible electronics.

This utility model discloses a waste gas treatment device for circuit board production, including an inlet pipe and a treatment tank. A cover is connected to the top of the treatment tank, which contains an alkaline treatment solution. An aeration pipe immersed in the alkaline treatment solution is installed inside the treatment tank. An activated carbon treatment box is located on one side of the treatment tank, and a UV treatment box is located on the other side of the activated carbon treatment box. This utility model introduces waste gas generated during circuit board production into the treatment tank, where it reacts with the alkaline treatment solution to remove acidic gases and dust. The gas is then further treated in the activated carbon treatment box to adsorb moisture and residual pollutants. Finally, the waste gas passes through the UV treatment box to treat organic waste gases. Compared to existing single-treatment methods, this utility model features high treatment efficiency and good treatment effect.
