Description

Technical Field

[0001] The utility model relates to the production field of calcium silicate boards, in particular to maintenance equipment for calcium silicate boards. Background Art

[0002] Calcium silicate board is mainly composed of silicate minerals, calcium minerals and fibers. As a green and environmentally friendly building material, it has potential carbon fixation ability during the production process. Silicate minerals and calcium minerals can react chemically with carbon dioxide to form carbonates, thereby achieving the fixation of carbon dioxide. This carbon fixation method helps to reduce carbon emissions during the production process of calcium silicate boards.

[0003] In order to deeply study the carbon fixation method of calcium silicate board, and to improve the carbon fixation efficiency of calcium silicate board without affecting the performance of calcium silicate board, it is necessary to cure calcium silicate boards with different formulations in different concentrations of carbon dioxide environment. Through repeated experiments, the performance changes of calcium silicate board during the curing process and the consumption of carbon dioxide are observed, which can provide experimental basis for the carbon fixation technology of calcium silicate board.

[0004] However, the existing experimental maintenance equipment has shortcomings in handling high-concentration carbon dioxide. When taking and placing calcium silicate boards, high-concentration carbon dioxide is easy to leak, posing a threat to the health of experimenters. In addition, the leaked carbon dioxide may also pollute the environment, which is contrary to the original intention of carbon fixation technology. Summary of the invention
