Abstract

The invention provides a photocatalytic reagent which has the chemical composition of any one of TiO2, La-doped TiO2, Nb-doped TiO2 and Bi-doped TiO2. The invention also discloses equipment applying the photocatalytic reagent on aluminized paper. A waste gas outlet is formed in a photocatalytic reactor; ultraviolet lamp tubes are arranged on the inner side wall of the photocatalytic reactor on two sides of the waste gas outlet; a rotatable rod is arranged at a position, which is 3-8cm away from the ultraviolet lamp tubes; multiple hot air inlets are formed in the bottom of the photocatalytic reactor; and aluminized paper belt roller shafts are arranged on two sides of the photocatalytic reactor. The experiment proves that the degradation rate of formaldehyde and TVOC is increased along with the prolonged illumination time, the concentration of the formaldehyde is reduced along with the prolonged illumination time, the degradation rate of the formaldehyde and TVOC is not influenced by the coating thickness of the photocatalytic reagent, the photocatalytic reagent has repeatability on degradation, and the degradation rate of the photocatalytic reagent on the formaldehyde is not less than 85 percent.

Description

technical field

[0001] The present invention relates to a kind of TiO 2 and metal element-modified titanium dioxide photocatalytic reagent, which is applied to aluminized paper, and the invention also relates to equipment for applying the photocatalytic reagent to aluminized paper. Background technique

[0002] At present, the technologies for dealing with formaldehyde and TVOC of aluminized paper mainly include:

[0003] 1. Improvement of hot air circulation. By transforming the exhaust and air intake of the equipment, a part of the hot air exhausted can be recycled again, and the heat energy can be used efficiently. This technology is widely used, but the energy consumption is relatively large, and it cannot meet the requirements for products with high requirements and complex materials.

[0004] 2. Adjustment of heating method. In the preheating zone of the equipment and the first oven, the ordinary heating tube is replaced by an infrared electric heating tube. The in...
