Stone conservation

Stone conservation

Stone conservation is the protection agent brush, spray, paint, roll, pour and immersion methods such as protective agent is evenly distributed in the stone surface or penetrate into internal form a protective stone, stone is waterproof, stain resistant, acid and alkali resistance, aging resistance and resistance to freezing and thawing, biological attack and other functions, in order to improve the service life and performance of decorative stone effect.
the meaning of stone conservation:
1, protects stone from erosion and pollution of various substances, the stone keep "youth" and "showy" of hosting the games.
2, prevent the stone material pathological change in the decorative surface of the stone, to maintain long-term, good decorative effect.
3, to prevent outside moisture and substances harmful to the stone in the air invasion, ensure the stone face still after several years.
4, to prevent wet after construction and stone of Yin-Yang face after the rain, the stone is always showing nature, stunning textured appearance and characteristics.
5, prevent weathering of stone surface.
6, the repellent deep penetration inside the stone, so that stones long not subject to external corrosion of harmful substances.
7, resistance to ultraviolet rays in the atmosphere into stone damaged stone, anti-aging.
/> stone maintenance order at present, marble and granite building material decoration surface lots, some marbles loose material, high porosity and water absorption rate, especially in their daily walk on the ground wearing, natural weathering and the stone material pathological change situations will cause surface fuzzing, and explosive, such as damaged.
General construction in the past, most of stone without the conservation treatment, so the various lesions occurred shortly after completion of the works, such as yellowing, the efflorescence phenomenon.
the correct sequence:
1, with 50 mesh coarse disc, Grind the ground first, open pores on the surface of the stone;
2, air dry, depending on the ambient temperature. Ventilated for at least 24 hours;
3, curing agent, end of obstructing surface moisture and harmful substances rises, brushing dry after;
4, brushing and reinforcement materials the first concentration in dilute, let it penetrate into the cracks. Covering plastic film L2 hours to prevent solvent evaporation.  Second again coated have slightly thick, can repair fill hole and small gap, still with plastic film cover 12 hours;
5, and patch holes: with stick relay strong, and polishing sex good of glue, distribution lust, first fill big hole, again fill small hole, fill material is slightly higher than board surface, to completely cool dry;
6, and with 100# a 300# Butterfly tablets mill to rubber scar;
7, and with 500# a 3000# mill;
8, and polishing;
9, and do Crystal surface or waxing conservation;
By the order of the construction, in the grinding plates grain of didn't burst, polished and smooth as a mirror. Through a period of observation of macular is no longer generated.
stone
along with the development of crystallization and stone becoming more and more popular, decorative stone to magnificent modern building at the same time, but also to the owners of stone surfaces care annoyance, causing huge losses, unnecessary waste.
wax as the first stone care technologies, is still widely used. Of this technique relies on water-swelling with low molecular weight plastic material formed on the stone surface coatings protect substrates. But low surface hardness, color, and often fill wax should be polished every day consumes huge resources, and in the process using wax with black wax alloy sand pad, seriously damage stone surfaces, and strong alkaline solvent wax permeating stone material the formation of cracks. With development of first generation technologies will reduce the use of new technologies.
Crystal face processing technology in the 80 's. It also works in accordance with wax, solvents dissolved hardness higher molecular weight polymer at high temperatures when the mill high hardness coating. But the cost amazing! Need a dedicated machine, polishing for a long time. Formation of surface qualities outweigh substrate is uneven. In recent years, with the progress of science and technology, surface reforming of stone lattice, hard light technology has been introduced, we called the Crystal hard! Based on common cleaning machine using Crystal process system has now been born. Stones can be divided into two types of granite and marble, the same Crystal hard handling system is also divided into granite hard systems and hard marble ceramic system, both the same principle. Use pharmacy tools are largely the same. Crystal hardening agent is used in physics and chemical methods to achieve stone lattice softening of the surface layer. "Nylon" friction pad under the ground of dense molecular alignment layer, reaching lattice back in under the action of heat curing, this process can achieve significantly increased marble surface hard 2~3 a Mohs hardness and brightness but significant increases to 100 degrees or more, granite brightness increases to 90 degrees. This outstanding result, as long as the maintenance according to the regulations, lifetime. Old and new effects of disparities than wax. And can waterproof, anti-oil, anti-fouling effect.
