Imported marble is generally referred to as dolomite in the world. With its natural and simple texture and bright color, it is widely used in building interior wall. Due to its loose material, soft texture and relatively high water absorption rate, marble is widely used in building interior wall. There are more joint lines, so in the process of processing, transportation, installation and use, it is easy to appear various pollution and warpage deformation, easy to lose light and other phenomena, affecting the decoration effect, so the care of marble is also a required course in the nursing industry. To compare and analyze the condition of marble facing, nursing methods can be divided into:

1: Renovate and grind. 2: Local drop treatment. 3: Cleaning and protection. 4: Crystal polishing treatment. 5: Seamless filling treatment, etc.

Let's talk about the construction technology of renovation grinding treatment and crystal polishing treatment first

First of all, the waterproof should be done before the renovation and grinding, so as to reduce the water absorption of the stone as much as possible, so as to reduce the water absorption law of the stone. At that time, the waterproof effect will be reduced or disappeared due to grinding. If conditions permit, it is better to do waterproof again after 800 mm. In case of loose stone materials, such as white sand beige, sandstone, tropical rain forest and wood grain stone, high content of sealing and curing agent (such as super hard inorganic coating, silicone resin sealant with content of more than 40%) should be used for pre-treatment, so that the stone can not only fill the loose but also harden the material quality.

1. Rough grinding: use 50 mm, 150 mm, 300 mm, 500 mm steel stone resin hard grinding blocks (do not use soft water grinding plate for rough grinding, which is easy to cause waves and affect the flatness). The water supply for rough grinding is slightly larger, but remember not to be too much. After grinding each grinding plate, water shall be absorbed thoroughly. Check whether the deep stroke left by the cutting abrasive is ground with 50 mm grinding disc, and so on Body grinding 45% time is the key link to ensure the quality acceptance of the project completion.

2. Fine grinding: 800 mm, 1000 mm and 2000 mm steel stone resin soft water grinding plates are used. The fine grinding accounts for 35% of the whole grinding time. The initial light appears after the fine grinding to 800 mm, and the gloss reaches 50 ℃ after the fine grinding to 2000 ℃.

3. Fine grinding: spraying A2 grinding with 3000 ා diamond resin soft water grinding plate, ion exchange and fine grinding takes 20% of the total grinding time. After fine grinding, the glossiness is greatly improved, and the surface density of marble is increased, which lays a solid foundation for the polishing agent (NO2 + Q5 mirror repair agent) and enhances the adhesion of polishing materials.

4. Polishing: use the power above 2HP, rotate speed 175-210 rpm, weight 45-70kg crystal surface machine, animal hair pad with 70% animal hair content, 3M pad, nano pad, with marble mirror compound cream NO2, 2x mirror locking knife into emulsion Q5 for polishing and grinding. After polishing, the surface gloss of marble can reach at least 90-100 degrees.

5. When it is difficult to make transparent stone, such as jazz white and resin artificial stone, if the water is not bright enough after finishing the above method, spray A2 again, grind it with 3000 mm to dry, and then repeatedly use nano pad, with marble mirror compound cream NO2, 2x mirror locking knife into emulsion Q5 for polishing and grinding. Nano inorganic polymer copolymer forms a crystalline layer, which is glassy The effect of water brightness will definitely come out. It has high hardness, wear resistance, transparency, water resistance, anti fouling, anti slip and other functions.
