Problems solved by technology

Therefore, the cost is high, the workload of moving the cylinder is heavy, the experiment preparation time is long, and the development efficiency is low
If a nitrogen generator is used, it is expensive, bulky and has a relatively low utilization rate

Embodiment 1

[0114] Example 1, the vacuum in the irradiation box is evacuated to less than 50Pa at one time, and then filled with nitrogen, so that the oxygen content in the irradiation box is less than 100ppm. In this way, the nitrogen consumption is the smallest, and the vacuuming time is about for 60s.

Embodiment 2

[0115] Example 2, first vacuumize the irradiation box to 2000Pa, fill it with nitrogen to an atmospheric pressure, then evacuate it to 2000Pa, and then fill it with nitrogen to an atmospheric pressure, so that the oxygen content in the irradiation box is less than 100ppm. This method shortens the time for the oxygen content to reach the standard by about 10 seconds, and doubles the nitrogen consumption.

Embodiment 3

[0116] Example 3, only the vacuuming operation is carried out in the irradiation box, and the electron beam radiation curing experiment is directly carried out on the sample in a vacuum environment, no harmful gases such as ozone will be generated, and other gases will not be consumed, and only the time for vacuuming is required , no inflation time is required, so the research on the effect of sample irradiation can be carried out quickly, with low cost and high efficiency.

Abstract

The invention discloses an irradiation experiment device and an application method thereof, and the device comprises an irradiation box which is provided with a matched electron beam generation device; a gas supply mechanism which is used for providing nitrogen into the irradiation box; a vacuum pump which is used for vacuumizing the irradiation box, wherein a first valve is arranged on a first pipeline, communicated with the irradiation box, of the air supply mechanism, and a second valve is arranged on a second pipeline through which the vacuum pump is communicated with the irradiation box. The invention provides an irradiation experiment device and an application method thereof, the irradiation experiment device is applied to an irradiation experiment, the nitrogen consumption can be effectively reduced, the experiment time is shortened, the operation cost and the labor intensity are reduced, the experiment efficiency is improved, only 20L of high-purity nitrogen is consumed in one experiment, the consumption is reduced by about 10 times, the time is only 30 seconds, and the time is shortened by more than 10 times.

Description

technical field [0001] The present invention relates to the field of irradiation. More specifically, the present invention relates to an irradiation experimental apparatus and a method for its use in the case of electron beam experiments. Background technique [0002] Electron beam radiation curing has: basically no volatile solvents; thorough curing, no residual monomers and photoinitiators, especially in the field of food packaging; excellent product performance, no odor; energy consumption is only 100% of that of UV curing 5%, which is 1% of the energy consumption of ordinary thermal curing; the curing temperature is low, especially suitable for heat-sensitive substrates, and is a typical green technology. However, there is an obvious bottleneck in electron beam radiation curing: oxygen inhibition will occur, so it needs to be cured under the protection of inert gas. Generally, it needs to be carried out in a high-purity nitrogen (or other inert gas) environment, and th...
