Problems solved by technology

In the stone cultural heritage protection monitoring research project carried out in Germany, K.Kirchner and J.Zallmanig proposed a method for measuring the surface adhesion of pulverized stone using tape paper (see editors such as M.Auras: Leitfaden Naturstein-Monitoring, Fraunhofer IRB Verlag, 2011, P.58-64), the principle of this method is to measure the anti-drop ability of the tape on the powdered surface, but it does not directly reflect the degree of powdering

Embodiment 1

[0034] in-lab test

[0035] The purpose of this example is to simulate a chalked surface and evaluate the effect of the curing treatment.

[0036] The experimental area and materials used are listed in Table 1.

[0037] Table 1 Division of laboratory experiment areas

[0038]

[0039] Experimental steps:

[0040] ① Preparation of experimental background

[0041] Take 10g of slaked lime, 10g of pot bottom ash and 10g of raw soil, add 1000g of water and stir for 10 minutes with a speed of 500r / min;

[0042] After passing through a 120-mesh sieve, put it into a pressure watering can, and evenly spray it on the lime plastered wall. After curing, spray it 3 times and let it dry naturally for 2 days;

[0043] After removing the floating dust on the surface with a brush, spray the left area A with curing agent and let it dry naturally for 1 day;

[0044] ②Clean the glass slide with alcohol, spread the 3M adhesion test tape on the glass slide, cut it with a 3cm grid knife, cla...

Embodiment 2

[0056] Quantitative determination of pulverization degree on the surface of Liu's House Ancestral Hall in Jinggang Mountains without slogans

[0057] Built in 1824, the limestone surface of Liu's House Ancestral Hall in Jinggangshan has been pulverized, and some of the Red Army's revolutionary slogans have fallen off. The purpose of this example is to measure the degree of pulverization of facades with different orientations before the solidification protection construction is officially carried out.

[0058] Experimental steps:

[0059] ① Select test sites on the west, south and east facades of Liu's House Ancestral Hall. The surface to be tested is required to be basically flat, free from plaster peeling and serious deterioration, and free from damp efflorescence and plant diseases;

[0060] ②Clean the glass slide with alcohol, spread the 3M adhesion test tape on the glass slide, cut it with a 3cm grid knife, clamp it into the analytical balance with tweezers, weigh the mas...

Embodiment 3

[0069] Jinggangshan slogan solidification No. 1 experimental surface

[0070] The purpose of this example is to quantitatively test the pulverization degree of the plastered surface of the west facade of Liu's House in Jinggangshan after applying different surface inorganic curing agents.

[0071] Experimental steps:

[0072] ① Select the experimental area on the facade of Liu's House Ancestral Hall, avoiding the revolutionary slogans with high value that need to be protected, and make the surface as smooth as possible. Use a brush to remove surface dust;

[0073] ② Spray ethyl silicate ES in the experimental areas of A, B and C;

[0074] ③ After the ethyl silicate ES is solidified, spray anhydrous micron lime NML-010 in the experimental area B;

[0075] ④ After the anhydrous microlime NML-010 is solidified, spray ethyl silicate ES in the experimental area C;

[0076] ⑤ Clean the glass sheet with alcohol, spread the 3M adhesion test tape on the glass sheet, cut it with a 3...

Abstract

The invention relates to a quantitative determination method for surface chalking of inorganic non-metallic materials. The method specially comprises the following steps: 1), cleaning a glass slide, drying, paving an adhesion testing tape on the glass slide, cutting through a scriber, weighing mass, recording data, repeating for 2 times, and calculating an average value as weight M0 of a blank tape; 2), paving the adhesion testing tape on the glass slide, cutting through the scriber, adhering the tape to the surface of a material to be tested, flattening through a rolling roller for three times repeatedly, taking down the tape, weighing mass, repeating for 2 times, and calculating an average value Mn; 3), according to the calculation formula that epsilon is equal to (Mn-M0) / S, calculating a mass difference, the mass of powder stripped through adhering per square meter and calculating an average value of the data. Compared with the prior art, the quantitative determination method provided by the invention has the advantages as follows: quantitative determination and analysis are carried out through equipment and instruments with standard specifications, so that the accuracy is high, operation is convenient, the equipment is convenient to carry, the experimental data is easy to process and the experimental result is quantitative and can be obtained quickly.

Description

technical field [0001] The invention belongs to the technical field of building protection and relates to a method for quantitatively measuring the surface pulverization of inorganic non-metallic materials. Background technique [0002] Important cultural relics of brick, stone, and soil, such as stone carvings, brick carvings, and slogans and murals on the walls of historic buildings, will undergo surface pulverization during the natural degradation process. However, how to quantitatively measure the degree of surface pulverization, there is no corresponding method at present. If pulverization can be quantitatively measured, on the one hand, it can evaluate the degree of surface deterioration of cultural heritage such as masonry, and on the other hand, it can also quantitatively monitor and evaluate the quality and durability of technical measures such as surface curing. [0003] And the existing method for measuring surface layer pulverization that can be used for referen...
