Embodiment 1

[0023] Example 1: Measurement of air permeability of purple sand bottles made of natural purple sand "Dragon's Blood Sand"

[0024] Dragon's blood sand is a kind of brown purple sand mineral with reddish-brown streaks, grape-like hematite particles can be easily seen under the microscope, and its mineral specimens are as follows figure 1 as shown in a. Zisha teapots and teapots made with this mineral as raw materials and traditional handmade teapots, such as figure 1 b and figure 1 As shown in c, the texture is fine and the surface vitrification is weak. figure 2 a-b show the internal structure and surface structure of the mineral product respectively. The length of the white scale bar in the lower left corner of the figure is 50um; it can be seen that there are abundant internal pores and high density of surface pores (the pores are the black area in the figure, "o" indicates two coarse pores). The diameter of the pores is mostly about 2.5um, and the thick ones can reach...

Abstract

The invention discloses a method for measuring air permeability of purple sand pottery, which solves the traditional problem that the air permeability of purple sand pottery cannot be measured. The invention measures the air permeability of the purple sand by measuring the water permeability of the purple sand; the measurement accuracy is high, and in principle, as long as there is air permeability, it can be accurately measured; the measurement cost is extremely low, and does not involve high pressure, no operation risk, and no pollution. Waste generation.

Description

technical field [0001] The invention relates to a method for measuring air permeability of purple sand pottery. Background technique [0002] Zisha teapot is a representative product of Zisha pottery. It has become a treasure of Chinese ceramic culture because of its outstanding artistry and practicality. The primary feature of Zisha pottery such as Zisha pots is air permeability. In the national standard (GB / T 10816-2008), "good air permeability" is stipulated as the basic attribute of purple sand pottery; however, the standard does not give the standard or method for air permeability testing. It is also because the air permeability of purple sand pottery cannot be measured, which has caused cognitive confusion in the market and seriously hindered the development of the purple sand industry. [0003] For the gas permeability measurement of materials, the core idea of ​​the current solution is the "pressure difference method". The name of the complete set of equipment is ...
