Description

Filter paper composite set

Technical Field

The utility model relates to a filter equipment especially relates to a filter paper composite set.

Background

The infrared microscope is used for directly testing the chemical structure of a specific micro part of a sample on the basis of observing the appearance form or physical microstructure of the sample to be tested by the microscope, so as to obtain a high-quality infrared spectrogram of the micro-area substance. It combines the functions of micro-area observation and infrared measurement.

With the development of science and technology, the infrared microscope has more and more applications and wider range. The method is mainly applied to the following aspects of (1) the research of polymer organic materials: one is the measurement of multilayer polymers and the second is the profiling of laminated composites. (2) Application in micro-area analysis: the microscopic infrared is mainly characterized in that infrared spectrum analysis can be carried out on a solid sample on a milligram or microgram level, is basically a non-destructive testing mode, and can play an important role in micro-area analysis. The method comprises the following steps of firstly measuring micro particles, secondly measuring micro spots, for example, analyzing different light or dark micro spots on the surface of a medium carbon sample, and thirdly measuring micro pollutants, for example, finding about 1-2 ng of particles on a plating layer of a micro contact point in precise electronic equipment, and determining the substances through infrared microscope measurement. (3) Application in biochemical substance research: the method is effective for researching the molecular structure change of animal and plant cell tissues, and is also effective for researching the division condition of the medicine in the cells. (4) Use in detection analysis in the jewelry industry: the method is used for measuring substances such as water, CO2 and the like in a capsule in the gem, and is used for nondestructively measuring organic compounds in the gem or in cracks.

The utility model of plastics has brought very big facility for human life, because it has stable physicochemical property, by extensive use in each field of life production, nevertheless large-scale plastic production has also brought serious environmental pollution problem. It is statistically expected that over 3 million tons of plastic are produced annually on a global scale and that 10% of the plastic waste will enter the ocean, an order of magnitude increase in the amount of waste plastic entering the ocean by 2025 without improving the associated infrastructure for disposal of the waste plastic. There was a relevant study on plastics pollution in the ocean as early as the 70's of the 20 th century without much attention. Until the 21 st century, people were not aware of the ecological environmental issues that these plastic wastes would bring. Since 2011, the united nations environmental planning agency (UNEP) started to pay attention to the Plastic wastes in the ocean, and in the first united nations environmental conference in 2014, UNEP issued UNEP green Book 2014 and valuable plastics, and reports that the Plastic wastes growing in the ocean have caused serious threats to the survival of organisms in the ocean and extremely damaged the ocean ecosystem, so that the economic loss is up to $ 130 hundred million. The associated problems of micro-plastics have also attracted increasing attention.

The plastic particles are decomposed into plastic fragments with smaller particle sizes from large-size plastics through the processes of solar radiation, weathering, mechanical abrasion, seawater erosion and the like, and the plastic fragments are called as micro-plastics when the particle sizes are smaller than 5 mm. The particle size of the micro plastic is small, has the characteristics of stable chemical property and difficult environmental degradation, and therefore, the micro plastic can exist in the water body environment for hundreds of years or even longer. As a novel pollutant, micro plastic has become a hot research problem of marine pollution.

In the prior art, when an infrared microscope is used for qualitatively identifying the micro-plastic, the following problems exist: the micro plastic particles are too small to be distinguished by naked eyes, and need to be observed under a stereoscopic microscope and then subjected to qualitative analysis under an infrared microscope. However, after the plastic particles are switched to the infrared microscope, the inspector needs to search the positions of the plastic particles again and then perform point scanning inspection, which wastes a lot of time and labor. Therefore, it is urgently needed to develop a filter paper combination device to solve the problem that the micro plastic particles are difficult to locate and observe during the identification of the micro plastic particles.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned shortcomings of the prior art, the present invention is directed to a filter paper combining device, comprising: the box comprises a box cover and a box body, wherein the partition plate is positioned in the box body and divides the box body into a left box body and a right box body; the length of the positioning paster is 2-4 mm.
