The grinding and polishing of marble blocks is the former process of stone processing. Natural marble is also called marble. The main components are calcium carbonate, magnesium, sodium, silicon, etc. The hardness value of Mohism is about 4.5, and it is soft. Anti-weathering is poor, so it is easy to lose luster on worn surfaces. According to the degree of marble surface wear, choose to carry out mild, moderate, deep marble grinding renovation methods to refurbish the marble. Here's how to use marble grinding and refurbishment and marble grinding machine.
Marble grinding concept
Marble sanding refers to the pollution, weathering, holes, and lightlessness of marble decorative stone laid on marble floors, walls (or external walls), tabletops, pillars, etc. The solution is to use pharmacy, machinery, and tools. Such as washing, grinding, so that the marble plate surface and the initial installation before laying a photo of the same and more ornamental effect of a process.
Marble polishing renovation method
1. Completely clean the ground, remove the concrete slurry from the stone gap with a cutter, and then use a brush, vacuum cleaner, etc. to completely remove the dust. Clean it with a dry, clean mop, with no sand or impurities on the floor.
2. After the stone surface is completely cleaned, use a marble adhesive to repair the small damaged points and stone seams above each stone. First, repair the damaged surface with a marble adhesive that is close to the stone color. Then use a special stone slotting machine to neatly cut the slits in the original stone installation, so that the width of the gap is consistent, and then fill it with marble glue that is close to the color of the stone. After the marble glue is repaired, it must wait for the glue to dry before it can do the next process.
3. After the marble glue is dry, use the grinding machine to grind the whole ground, and the whole surface is polished horizontally, with the key to grinding the caulking glue between the stone and the edges near the wall, decorative shapes and shaped shapes to keep the overall stone ground level. , Finished the first time of grinding, re-mosaic marble caulking, caulking is completed to continue grinding for a second time, and then stone refurbished machine equipped with steel feldspar Shuimo tablets from coarse to fine, a total of seven times to complete grinding and polishing The ground is generally flat and smooth, and then steel wool is used for polishing. The polishing degree reaches the brightness required for the design, and there is no obvious gap between the stones. (Granite refurbishment must use bridge mills and professional grinding plates, do not use resin grinding plates. Coarse grinding: can not reduce the number of grinding times and change the number of grinding mesh. 60-mesh grinding stone polished stone floor, height difference, Scratches and deformations are basically the same, and they must be full. Fine grinding: It is not allowed to reduce the number of grinding passes and change the mesh number.)
4. After the sanding is completed, use the suction machine to treat the water on the ground, and use the blow dryer to dry the entire stone floor. If time permits, you can use natural air drying to keep the stone surface dry.
5, the ground side evenly sprayed syrup, while using a marble polishing machine to grind, use the washing machine with a red scouring pad, the syrup with the same amount of water sprinkled on the ground, began to grind, the role of thermal energy to crystal surface material in the stone surface crystal After the formation of surface effects.
6, the overall surface conservation treatment: If the stone is a large void to be marble protective agent brushing, re-polishing once, in order to increase the hardness of the entire surface of the crystal face.
7, ground cleaning and maintenance: When the surface of the crystal stone crystal mirror, use a vacuum cleaner to suck off the ground residues and moisture, and finally polished with a polishing pad, so that the entire ground is completely dry, bright as a mirror, if local damage can be partial maintenance, After the completion of the construction, you can walk up and down at any time. (After the stone surface is dried, do crystallization and hard treatment until it reaches the surface effect required by the model. The refurbished travertine stone surface reaches a mirror gloss of 60 degrees or more, and there must be no difference in the height between the stones. The granite stone surface is reached. Above 80 degrees, there must be no leakage of glue.)
Marble grinding machine
Marble grinding machine, also known as marble refurbished machine, is mainly used for marble renovation crystal surface, granite crystal surface maintenance. In particular, areas with excessive ground flow are prone to wear and tear, and the cost of re-decoration is too high, and the time is too long. Therefore, marble retreading is the use of chemical and physical methods in a short time, on the basis of the original marble grinding machine. Grinding, polishing, restoring it to the original brightness and color of the stone, the brightness of the marble grinding machine after refurbishment can reach 100% when just laying, economical and time-saving, the service life of the stone after refurbishing by the marble grinding machine is five years the above.
Marble grinding machine using method
1. Plug in the power plug and turn the handle to the vertical position, then lay the machine back flat on the ground. Then install the brush or needle seat.
2. Rotate the needle holder or brush to the right and install it on the motor gear buckle.
3. If using a needle holder, you must put a fiber mat.
4. Put the stone crystal processor back on the ground and turn the handle down to the proper position.
5, plug in the power plug, press the safety button, grab the left / right switch handle to start the machine.
6. After use, unplug the power plug and remove the retread plate/seat holder. Dry the stone crystallization machine and store in a ventilated place.
Marble grinding machine equipment selection
The invention of the marble grinding machine solved the need for leveling, polishing, polishing and the like of the stone floor. Therefore, the marble grinding equipment is a stone conservation machine with excellent features and easy operation and flexibility. However, whether the machinery is easy to use, but also the choice of local conditions, should be based on the specific use of personal needs to choose.
1, according to the marble floor texture and the degree of wear and tear. It is recommended to use a large-scale stone refurbishing equipment using a physical grinding method, the effect is better than simply using chemical products for renovation grinding.
2, the use of marble grinding machine grinding marble must meet two conditions: First, the weight of marble grinding machine; Second, the speed of marble grinding machine. That is, a high-weight and low-speed machine is required in the marble grinding process, and crystal polishing is a low-weight and high-speed machine.
Editor's summary: Information on how to refurbish the marble and how to use the marble grinding machine was introduced here. I hope this article will be helpful to everyone.
