Description

[Technical Field]

[0001] The present invention relates to a container, and more particularly to a calcium oxide container capable of absorbing carbon dioxide. [Background technology]

[0002] As the concentration of carbon dioxide in the atmosphere increases, the Earth's temperature also rises, and rising global temperatures have various effects on the human living environment, such as making the weather more unstable and reducing crop yields. On the other hand, carbon dioxide capture technology and carbon dioxide sequestration and storage technology have great potential for development as effective means of reducing carbon dioxide emissions, and are attracting international attention.

[0003] In industry, carbon dioxide capture loops are in place that separate the mixed exhaust air emitted by utilities such as power plants and factories to obtain carbon dioxide gas, which is then compressed and sent to a processing unit for storage. Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned methods are only applicable to the exhaust gases of business entities, and it is difficult to use these methods to capture carbon dioxide from exhaust gases emitted by ordinary people in their daily lives. Therefore, there is a great need to develop a means to directly capture carbon dioxide in people's daily living environments and mitigate the effects of global warming.

[0005] In view of the above problems, an object of the present invention is to provide a calcium oxide container. [Means for solving the problem]

[0006] The present invention provides a container body that defines a storage space and an opening that communicates with the storage space; a lid body that removably covers the opening of the container body 1, The present invention provides a calcium oxide container, wherein at least one of the container body and the lid contains a polymer material and calcium oxide capable of absorbing carbon dioxide. [Effects of the Invention]

[0007] The calcium oxide container of the present invention can not only store items (such as beauty products, cosmetics, etc.), but also absorb carbon dioxide from the environment, thereby reducing carbon dioxide emissions and mitigating the environmental impact of global warming caused by carbon dioxide.

[0061] <Examples 3 and 4> Examples 3 and 4 were produced in the same manner as Example 2, except that the amounts of each component shown in Table 1 were different.

[0062] <Comparative Example 1> Comparative Example 1 was prepared in the same manner as Example 2, except that calcium oxide was not added, as shown in Table 1.

[0063] [Table 1]

[0064] <Evaluation items> The calcium oxide bottles of Examples 1 to 4 and the bottle of Comparative Example 1 were subjected to the following tests.

[0065] For a detailed explanation, the calcium oxide bottle of Example 1 will be taken as an example.

[0066] <Carbon dioxide absorption measurement> The measurements were conducted at the request of the Plastics Industry Development Center, a Taiwanese foundation, in accordance with the organization's internal document SOP C025-01.

[0067] The five calcium oxide bottles of Example 1 were left standing in a ventilated indoor environment at 28°C, and after 0, 3, 6, 9, and 12 months, a portion of each calcium oxide bottle was cut out to prepare a measurement sample.

[0068] Each sample was placed in a thermogravimetric analyzer (manufacturer: TA, model number: Q500 / A149) and heated in a nitrogen atmosphere at a heating rate of 20°C / min. The sample was then heated from 40°C to 800°C, and cooled at a cooling rate of 20°C / min to obtain the residual mass. The amount of carbon dioxide lost between 500°C and 750°C was calculated, which was the amount of carbon dioxide in the sample. Based on this amount of carbon dioxide and the CO2:CaCO3 molar ratio of approximately 1:1, the calcium carbonate content (wt%) was calculated.

[0069] The residue was then analyzed using a Fourier transform infrared spectrometer (manufacturer: PerkinElmer, USA, model number: Sepctrum TWO), and the wave number was approximately 1470 cm -1 and about 875 cm -1 The presence of these characteristic peaks proved that calcium oxide was indeed added to the calcium oxide bottle of this invention.

[0070] The weight ratio of CaO:CO2:CaCO3 before heating was calculated based on the calcium carbonate content and the ratio of molecular weights of CaO:CO2:CaCO3 of 56:44:100, and the carbon dioxide absorption rate (unit: %) was calculated based on the calcium carbonate content and the weight ratio of CO2 to CaCO3. At the same time, the amount of carbon dioxide absorbed by the entire bottle (unit: grams) was calculated based on the carbon dioxide absorption rate and the weight of the bottle before the sample was cut out. Carbon dioxide absorption rate (%) = calcium carbonate content (wt%) x (weight ratio of CO2 to CaCO3) Amount of carbon dioxide absorbed (grams) = [Bottle weight (grams) x Carbon dioxide absorption rate (%)] / 100

[0071] <Buckling test> Room temperature water was poured into ten calcium oxide bottles of Example 1 up to approximately 80% of the total volume to obtain multiple test samples. Using an analytical measuring instrument (manufacturer: Shimadzu Corporation, model number: AGX-5KNX), the multiple test samples were measured at a speed of 20 mm / min, and the pressure at which the downward pressure deformation reached 4 mm when pressure was applied downward from the mouth of the bottle was recorded, and the average pressure value of the ten bottles was calculated.

[0072] <Drop test> Ten calcium oxide bottles of Example 1 were filled with water at 20°C and left to stand at 20°C for 24 hours.

[0073] All calcium oxide bottles were placed at a height of 1 meter and then allowed to fall freely. This free fall was repeated a total of five times, and the appearance of each bottle was visually inspected for any ruptures. The evaluation criteria were as follows: ◯ indicates no ruptures, and × indicates one or more ruptures.

[0074] <Environmental Stress Cracking Resistance (ESCR) Measurement> Ten calcium oxide bottles of Example 1 were filled with bleach up to one-tenth of the bottle's height, and placed in a thermostatic chamber set at 65°C. The bottles were visually inspected for any signs of rupture, and the inspection was stopped after 300 hours. The evaluation criteria were as follows: ◯ indicates no rupture, and × indicates one or more ruptures.

[0075] <Antibacterial measurement> According to ISO 22196 (2011 version) antibacterial performance test method for plastics and other non-porous surfaces, the color masterbatch in Example 1 was pressed into a sheet to obtain a test sample with a length of 5 cm, a width of 5 cm and a height of 0.2 cm, and the test sample was then sent to the Taiwan testing center of BOKEN (BOKEN QUALITY EVALUATION INSTITUTE) for testing.

[0076] The bacterial strains used for the antibacterial tests were Staphylococcus aureus (Deposit number NBRC 12732 at the National Institute of Technology and Evaluation (NITE) Biotechnology Center) and Escherichia coli (Deposit number NBRC 3972 at the National Institute of Technology and Evaluation Biotechnology Center). The test time was 24 hours, the inoculum volume was 0.4 mL, and the cover film dimensions were 16 cm. 2 is.
