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

Example Embodiment

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

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

[0021] 2. Assemble non-freezing model ice preparation mold and gas injection device. Use prefabricated ABS sheet as per figure 1 with figure 2 The non-freezing model ice preparation molds are spliced ​​and assembled as shown in the pattern, and the outside of the plate is fixed with tape to facilitate disassembly of the mold when taking out the mode...

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...
