Stone processing is one of the important links in stone production. In addition to the quality of the stone itself, the processing method is also very important. Then, what factors will affect the stone processing? Today, we talk to the FABULOUS Group editor Take a look.
The composition of stone
The forming components of stone include mineral and chemical. Different mineral and chemical components have different processing properties. For example, marble, the main mineral components are calcite and dolomite, and their Mohs hardnesses are 3 and 3.5-4 respectively, which are lower than granite and are easier to process. The main minerals of granite are quartz, orthoclase and plagioclase, and their Mohs hardness is 6.5-7. Its workability largely depends on the content of quartz and feldspar, the higher the content, the more difficult it is to process. In terms of chemical composition, such as the higher the SiO2 content, the more difficult it is to process.
The internal structure of stone
Generally speaking, the structure of stone with uniform particles is easier to process than uneven ones; fine particles have higher polishing quality than flakes; dense stone has higher gloss than loose stone; mineral crystallinity is good, and the orientation arrangement and optical axis The same direction will greatly improve the gloss after polishing.
hardness
Under normal circumstances, the greater the hardness of the stone, the more difficult it is to process, the higher the technical requirements for forming, and the greater the wear on processing tools. When the hardness of the stone increases, the abrasion resistance will also increase, so the cutting resistance will increase, and the requirements on the processing tools will be higher.
