As a high-grade decorative material, stone is widely used in building surface decoration, so the maintenance and maintenance of stone is increasingly urgent and important.
  In the renovation process of stone fire-burning board, flame spraying is used to move uniformly on the board surface. The moving speed is 120-250 mm per second, the distance between the nozzle and the board surface is 20-40 mm, and each other is inclined. The temperature of the flame is 800-1000 C. Before flame spraying, water is sprayed first on the board (to prevent burning of the board during flame spraying, water is heated and evaporated to absorb heat). Make it fall off the surface layer of 0.5-1 mm. The granite material processed by this method exposes the original characteristics of the stone, which is simple, rough and natural. Then the stone is maintained and protected by the method of anti-fouling and anti-seepage treatment. The methods are as follows:
  Stone anti-fouling and anti-seepage treatment is to use the strong penetration of anti-seepage agent, not forming a film on the surface, infiltrating into the internal micro-pore, forming a nano-spherical crystalline curing layer, that is, it can prevent the entry of a variety of water pollutants, but also can not affect the color and permeability of stone, avoiding stone pathological changes caused by moisture retention inside the stone; dust and pollution can only float on the surface of stone. Face, easy to clean. Waterproof and anti-fouling protector has strong penetration and plays a maintenance and protection role on the stone surface of buildings.
  1. It will not change the performance and color of stone surface.
  2. Effective and durable prevention of sewage infiltration, dust attachment, keep the surface of treated stone clean;
  3. Sustainable and effective prevention of erosion and destruction of water, freezing and air pollution;
  4. It has 100% air permeability and keeps the original air permeability of the building.
  5. Inhibiting the growth of mould, moss and macula for a long time.
  6. Improving heat insulation, anti-ultraviolet performance, protecting stone surface color and preventing fading;
  7. It has the ability of self-cleaning and self-purification. The wind and rainwater can clean the surface dust and wash it with high-pressure water without damaging its surface effect.
  8. Effective prevention of edible oil, blue and black ink, fruit juice, coke, coffee, tea, soy sauce, red wine and other non-ferrous water pollution, easy to maintain and clean. Maintain the natural color appearance and air permeability of the substrate.
  To maintain ventilation and drying, the fire board is afraid of too much humidity, water and gas will produce hydration, hydrolysis and carbonation of stone, resulting in water spots, whitening, weathering, denudation, rust and other pathological changes.
  All fired slate and stone materials are afraid of acid and alkali, which will make the fired slab yellowing, the surface of the fired slab eroded, and alkali will also cause the crystal spalling of the fired slab and make the surface gloss of the fired slab lost. Cleaning agent with neutral acid-base value should be used. Only mild soap and water are needed for daily cleaning of fire boards.
  In addition, the surface of the burning board should not be covered with carpet for a long time, otherwise the stone will be damaged due to excessive moisture and increased moisture content. If carpet is laid or sundries are piled up, it needs to be changed frequently. Once oil, tea, coffee, etc. are poured on the stone, it must be cleaned immediately to prevent infiltration into the stone pore. All stones have natural capillaries. If dirt is not treated in time, it will easily penetrate into the interior of stones, forming a nasty stain.
