Problems solved by technology

The existing non-freezing model ice preparation technology needs to stir the mixed solution evenly when configuring the model ice preparation, and then does not intervene in the crystallization process during the solidification stage of the mixture solution, so the obtained non-freezing model ice does not have the columnar texture of natural sea ice The structure, the mechanical characteristics shown will be different
[0009] (2) The non-frozen model ice prepared by the existing technology does not have the characteristics of the distribution of internal defects along the columnar texture structure of natural sea ice
However, the crystallization process of the existing preparation technology determines that the defect structure is uniformly distributed in the model ice, and does not have the characteristics of the distribution of defects along the columnar texture structure in natural sea ice

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with examples.

[0020] 1. Prepare the paraffin wax mixture solution. In order to effectively simulate the density of natural sea ice, paraffin wax with a density similar to sea ice was selected as the base material. Heat the solid paraffin until it completely melts into liquid paraffin. In order to improve the brittleness of non-frozen model ice and make it more similar to natural sea ice in terms of mechanical properties, 1% gypsum powder, 3% quartz powder and 1.5% silicon powder were added to liquid paraffin, and stirred evenly for later use.

[0021] 2. Assemble the non-frozen model ice preparation mold and gas injection device. Use prefabricated ABS panels according to figure 1 and figure 2 Styles shown are spliced ​​and assembled with non-frozen model ice preparation molds, and the outside of the sheet is secured with tape to facilitate removal of the mold when removing the model ice. The...

Abstract

The invention relates to a device for preparing non-frozen model ice with columnar texture characteristics. The device comprises a non-frozen model ice preparation mold and a gas injection device, wherein the mold comprises a mold outer plate and a mold making chamber; the mold making chamber is defined by the mold outer plate, namely a mold upper cover plate, mold side plates and a mold bottom plate; a gas injection hole array is formed in the mold bottom plate; a device used for heating the bottom plate is arranged at the mold bottom plate; the gas injection device comprises a gas injectionpipe array, a pipe separator, a gas inlet pipe and a gas pump; the gas injection pipe array is arranged below the mold bottom plate and corresponds to each gas injection hole; each gas injection pipeis connected with one end of the gas inlet pipe through the pipe separator; and the other end of the gas inlet pipe is connected with the gas pump.

Description

technical field [0001] The invention belongs to the technical field of engineering in alpine regions, and relates to a non-freezing model ice generation and preparation method for simulating sea ice in alpine regions. Background technique [0002] Physical model test is an important means in the research of ice mechanics and ice engineering. The preparation of model ice that can effectively simulate the physical and mechanical properties of natural sea ice is the basis for ice mechanics model experiments. At present, there are mainly two types of model ice used by research institutions in various countries in the world, namely low-temperature freezing model ice and non-freezing model ice. Low-temperature freezing model ice can truly simulate the growth process of natural sea ice. There are relatively mature technologies to ensure that the microstructure of model ice is similar to natural sea ice, thereby effectively simulating the physical and mechanical properties and fail...
