A simulation method for micro-crack generation in antique ceramics

Abstract

Relating to the technical field of protection of cultural relics, the invention discloses an antique ceramic microfissure generation simulation method, which includes: A) taking a ceramic and drilling several holes on one line on the surface, with the hole diameter being 4.5-5.5mm, the hole depth being 2.5-3.5mm, and the hole spacing being 8-15mm; B). adding slaked lime and cement into water and stirring the mixture evenly to obtain a filler, with the mass ratio of the slaked lime, cement and water being (35-45):(35-45):(15-25); C). filling the holes of the ceramic with the filler till overflow; and D). pressing the holes on the ceramic surface by a weight, placing the weight for 18-30h and then removing the weight, thus obtaining the antique ceramic with microfissures. The method provided by the invention has the advantages that: 1. the simulation degree is high, the microfissures can be consistent with the fissures of a simulated antique ceramic object; 2. the method is simple, the cost is low, the speed is fast, and the effect is good; 3. the microfissure generation stability is good, the microfissure size is controlled artificially, and antique ceramics with different cracking degrees can be simulated; and 4. the filler is non-toxic, harmless, pollution-free and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of cultural relics protection, in particular to a method for simulating micro-cracks in antique ceramics. Background technique [0002] Ceramics are utensils made of clay as raw material and fired at a certain temperature. Its main components are silicate minerals, such as feldspar and quartz. The earliest pottery in China is about 10,000 years ago. The invention of pottery is an important symbol of the division of the old and new stone ages, and it is also a bright pearl in the treasure house of cultural relics in my country. Most of the ceramic relics excavated have fragmented cracks. Therefore, the generation simulation of ceramic microcracks is of great significance in the process of ceramic repair and bonding, and it is also a research field that has been missing. In order to meet the crack conditions of precious ceramic cultural relics, it is necessary to simulate the micro-crack generation of ordinar...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there are few studies on the simulation of ceramic microcracks. Some methods perform accelerated aging treatment on ceramics to make them naturally crack. It is artificially controlled, so it is impossible to simulate the ancient ceramics of the specified object, and the degree of simulation is low

Some methods use physical methods to apply force to the ceramics. This method has a large degree of damage to the ceramics and has the same problems as the accelerated aging method.
