In the conservation of stone, if the poor quality of the selected curing agent, can not play after using the conservation of stone feature, the occurrence of stone disease, and its subsequent processing and removal of these failures must first curing agent, but its cost more expensive. Stone curing agent now many brands available in the market, the quality varies greatly, how to choose a good curing agent, so that the conservation of stone with excellent results, it becomes very important. Therefore, the conservation agent to determine the law applies or not to make some simple introduction.
First, the anti-pollution test
In the stone surface a few drops of the sources of pollution, such as tea, coffee, cooking oil, soy sauce, ink, standing 8-12 hours later, using toilet paper wipe and wash with water. Observe the surface contamination situation, the better the quality of curing agent, the more difficult sources of pollution into the stone, so the lower the level of pollution, and even will not cause pollution.
Second, the allocation of water testing
Stone conservation agent with the allocation of water features, its pros and cons of the effect of water allocated or not, as the drops of water conservation in the treatment worked stone surface will show bead-shaped or spread-shaped may be. When the larger Limestone, the better the stone surface hydrophobicity, the more difficult it drops into the stone pores, the water from the stone back to the stone surface is also difficult to penetrate, thus preventing the occurrence of stone disease. When we spread the fingers to fiddle with water droplets, we can observe the diffusion speed of water droplets gather once again, if the re-aggregation of the faster curing agent, said the allocation of water-based stone the better.
Third, the blue ink immersion test
Stone on the back of the cement mortar containing calcium hydroxide ions substances, it is easy to be a lot of water and then dissolved within the stone caused by water infiltration into the plaque, Bai Hua, rust and yellow, and other stone disease. Blue ink are ionic substances, and some characteristics similar to cement mortar, it can simulate the situation of water spots occur, the following simple experiment that provides a quick test the function of curing agent.
Test the general steps, the first 2 cm thick stone placed in shallow dish, add blue ink solution (20% water mixed with blue ink painted) from the submerged to 0.3 cm at the bottom of the stone, and often joined the blue-ink solution in order to maintain a constant Sandstone, for 15 days after the observation of blue ink to penetrate the stone surface of the case. Good quality curing agent, and blue ink, difficult to penetrate the stone surface, which can determine the conservation function of the curing agent is good or not.
