Embodiment 1

[0020] In the light reactor with a diameter of 800 mm and a height of 400 mm, there is a flat paddle stirrer, the paddle is fixed with a stainless steel screw and a PTFE scraper with a thickness of 3 mm, the stirrer rotates at 24 rpm, and there is steam at the bottom Heated oval head jacket. Two sets of 2KW ultraviolet lamps are placed on the top (including ultraviolet lamps and lamp cooling fans). In this equipment, 5 kg of preliminarily refined lacquer wood wax was put in, and the steam at the bottom was heated for about 15 minutes to melt it. Turn off the steam, turn on two ultraviolet lamps, and open the top exhaust system. Sampling every minute. Under the action of ultraviolet light, lacquer wood wax will become lighter in color due to the oxidation and degradation of aldehydes present in it. The specific test results are as follows:

[0021] Lighting time 0 minutes 5 minutes 10 minutes 15 minutes

[0022] Chroma 8 7 6 6

[0023] It can be seen that the color of lac...

Embodiment 2

[0025] With the same equipment as in Example 1, turn on a group of ultraviolet lamps, feed 5 kg of lacquer wood wax in the same way, control the reaction temperature at 70-80 ° C, and measure the results at different times as follows:

[0026] Lighting time 0 minutes 5 minutes 10 minutes 15 minutes 20 minutes

[0027] Chroma 8 7.5 7.0 6.5 6.0

[0028] It shows that the reaction time is inversely proportional to the light intensity.

Embodiment 3

[0030] With the same equipment as in Example 1, turn on two sets of ultraviolet lamps, feed 5 kg of lacquer wood wax, and add 10 g of benzophenone, control the reaction temperature at 70-80 ° C, and measure the results at different times of light as follows:

[0031] Lighting time 0 minutes 5 minutes 10 minutes 15 minutes

[0032] Chroma 8 6 5 5

[0033] It shows that the color of lacquer wood wax can be rapidly and effectively reduced by adding photoinitiator.

Abstract

The invention discloses a high-strength illumination reaction kettle and belongs to the technical field of chemical machinery. The high-strength illumination reaction kettle consists of a kettle body (1), an ultraviolet lamp tube group (2), a folded oar stirrer (3), a plastic scraper blade (4), a cooling fan opening (5), a heating or cooling coil (6) and a heating or cooling seal head (7). The initiation reaction activity is higher, and the initiation reaction is not a free radical chain reaction, such as a high-energy photolysis reaction and the like, so special reaction conditions, such as high illumination intensity, adjustable illumination and reaction time, enough exposure area and the like, are required. The high-strength illumination reaction kettle is designed for the conditions.

Description

technical field [0001] A high-intensity light reaction kettle, the invention relates to a high-heating-intensity and dryable melting equipment, which belongs to the technical field of chemical machinery. Background technique [0002] In the conventional chemical reaction process, many reactions require a certain amount of energy, including heat energy, light energy, electromagnetic wave, ultrasonic wave, radiation energy and other external energy, and in the presence of a catalyst that reduces the reaction activity energy, the reaction is initiated (started), continued and terminated. The initiation and promotion of chemical reactions by light irradiation is a branch of the chemical reaction process. The traditional photoinitiation reactor is based on an ordinary chemical reaction kettle, with an ultraviolet lamp on the top, a conventional stirring device (paddle type, anchor type, frame type, pusher type, etc.) inside the kettle, and a clip on the outside. Jacket or half t...
