Description

Weather resistance detection device for novel printing ink material production Technical Field The invention belongs to the field of weather resistance detection of ink materials, and particularly relates to a weather resistance detection device for novel ink material production. Background The ink material, especially the novel high-performance ink, is increasingly widely applied in the fields of outdoor advertising, package printing, industrial identification and the like. The weather resistance, namely the capability of resisting ageing of environmental factors such as illumination, temperature, humidity, rainwater and the like, is a key index for determining the service life and performance stability of the product. Therefore, in the development and production stages, it is important to perform accelerated weather resistance detection on the ink material. Currently, a common weather resistance detection apparatus generally includes a detection box in which components simulating natural environments, such as a light source (simulating sunlight), a heater (simulating high temperature), a shower (simulating rainwater), and the like, are disposed. These devices are capable of performing accelerated aging tests on ink-coated substrate samples in a confined space. However, there are several significant problems with existing detection devices: Firstly, environmental parameters in the detection box, such as temperature, humidity and irradiance, are often unevenly distributed, so that the tested conditions of the samples are inconsistent, and the comparability and accuracy of the test results are reduced. Secondly, the traditional control mode is rough, set point control is usually carried out on a single parameter, the overall state evaluation of the detection process is lacked, and the comprehensive influence of various factors such as light source attenuation, sample initial state difference, temperature and humidity fluctuation and the like on the final detection result cannot be reflected in real time. In addition, the air flow organization is critical to the uniformity of the environment in the box, but the air flow regulation mode of the existing equipment is simpler, or is not adjustable, or has single adjustment dimension (such as only adjusting the rotating speed of a fan), and is difficult to realize rapid and accurate environment equalization, so that the reliability of detection data is influenced. More importantly, the prior art lacks collaborative evaluation and intelligent regulation capability for a plurality of key parameters in the detection process. For example, the degree of influence of the state of the detection variable, the state of the detection process, and the state of the sample on the final detection result cannot be quantitatively evaluated, and the airflow control strategy cannot be dynamically optimized according to these evaluation results. This limitation makes it difficult to ensure the reliability and repeatability of the detection results, which is detrimental to the development and quality control of the ink material. In view of the above, there is a need in the art for improvements. Disclosure of Invention The embodiment of the invention aims to provide a weather resistance detection device for novel ink material production, which aims to solve the problem that the prior art lacks collaborative evaluation and intelligent regulation and control capability for a plurality of key parameters in the detection process.
