Construction stone processing is a basic and important process that refers to all the processes that prepare a stone for installation and use in a building. We can use different methods to process stones, and these processing methods can be different depending on the type of stone.
Stages of stone processing
Building stones are created in different categories, which according to their characteristics, each of them can be used for different parts of the building. In order to use stones in different parts of the building, payments should be made on the surface according to the place where the stone is to be used, which we review below:
1 - Construction stone cutting
The first step in construction stone processing is cutting construction stone in different dimensions. At first, the stones come to the stone exhibitions in the form of a cup or uncut.
When the building stones come to the quarries in the form of a cup, they are cut with the help of devices equipped with a steel blade and diamond teeth or disc and wire.
2 - Strengthening the stone
One of the most important features that a building stone should have is the strength of that building stone.
Building stones often have high strength; However, to increase their resistance, various methods and solutions are used. One of these solutions is the use of lace and resin.
3 - Stone working resin
Stone resin (stone polishing) is a transparent liquid based on acrylic copolymers, which is used in stone processing. It is also a very good protection for the facade of the building, which can be used on all surfaces. For this reason, it will prevent the penetration of water into the building.
Many stones, such as travertine, naturally have many holes and pores, and this reduces the beauty of the stones. Of course, the presence of voids has benefits and makes the stone lighter and increases the adhesion of the stone with the mortar. These voids and voids on the surface of the stone must be filled so that the stone is resistant to water and Moisture is impermeable. Materials called epoxy and polyester mastics are used to fill these gaps and voids.
It is interesting to know; All these materials are made of resin and are available in transparent and colored forms.
Using these materials increases the resistance and beauty of the stone.
4 - Construction stone grinding
Construction stone grinding is very important in construction stone processing.
After the stones are in the dimensions The desired sizes were cut and the defects and voids of the stone were filled with the mentioned materials, they are ready for sanding. If the stone is soft like marble and marble or hard like granite, their polishing will be different, and for each of them, special abrasives are used for subbing and polishing.
At this stage, using the machine Sub, the surface of the stones becomes smooth and polished. This issue is very effective on the beauty of the stone and also fills its very small defect. Above, in the next stage of stone processing, it comes to the edging stage, which needs to be polished on the edges of the stone. In this stage, we use sanding wheel systems. > Edging machines can create round, semi-round and beveled edges.
