In the process of stone deep processing and post-maintenance, abrasive abrasives are widely used. Abrasives industry is a basic industry, but it always occupies an extremely important position in machining. Stone processing equipment includes sawing processing equipment, grinding and polishing processing equipment, and special-shaped processing equipment. Stone overall grinding and refurbishment companies also often use abrasive pads. Today, let’s talk about the application of abrasives in the stone care industry.
abrasive
Abrasive abrasives are tools used for grinding, grinding and polishing. Abrasive abrasives are widely used in the processing of non-metallic materials such as stone, ceramics, and glass, as well as in machinery manufacturing and other metal processing industries. During the use of the abrasive tool, when the abrasive grains become blunt, due to the partial fracture of the abrasive grain itself or the fracture of the bond, the abrasive grains fall off partially or completely from the abrasive tool, and the abrasive grains continue to act on the working surface of the abrasive tool New cutting edges appear, or new sharp abrasive grains are constantly in contact, so that the abrasive can maintain the grinding performance for a certain period of time. This self-sharpening of abrasive tools is a prominent feature of abrasive tools compared with general cutting tools.
abrasive material
Abrasives used in stone grinding and polishing mainly include common abrasive white corundum, black silicon carbide, green silicon carbide and diamond. White corundum microhardness 2200~2300kg/mm2, black silicon carbide microhardness 3100~3300kg/mm2, green silicon carbide microhardness 3200~3340kg/mm2, diamond microhardness 8000~10000kg/mm2, diamond microhardness 8000 ~10000 kg/mm2. Granularity number: Ovi 4#~WO.5 (finer).
From the order of hardness, processed granite can be divided into diamond, green silicon carbide, and black silicon carbide, and processed marble can be divided into green silicon carbide, black silicon carbide (hard), and white corundum (soft). From the analysis of material cost, it is diamond, green silicon carbide, black silicon carbide, and white corundum.
Introduction to the use and characteristics of diamond grinding discs
The use of diamond grinding discs:
Diamond grinding disc is the collective name of diamond water grinding disc and dry grinding disc. Diamond water grinding disc is also called diamond soft grinding disc. It is a flexible processing tool made of diamond as abrasive and combined with composite materials. Joints, used for grinding, can be used for processing special-shaped materials such as stone, ceramics, glass, floor tiles, etc. It is suitable for processing special-shaped stones such as polishing of stone, lines, and chamfering of curved panels. It can also be used for marble, concrete, Special-shaped processing, repair and refurbishment of cement floor, terrazzo, glass-ceramic, artificial stone, floor tile, glazed tile, glass brick, with strong grinding force, durability, softness, clarity and gloss, it is an ideal stone grinding tool , The whole process is divided into four stages: coarse grinding, fine grinding, fine grinding, fine grinding, and polishing. The glossiness of the processed stone can reach more than 90°.
Used for stone processing such as artificial stone, granite and marble. Diamond grinding discs have a complete range of particle sizes and colors and good flexibility. Lines, chamfers, curved plates and special-shaped stones can be processed freely. There are various specifications and shapes available. Choice, a variety of particle sizes are easy to identify, and can be flexibly used with various hand grinders according to needs and habits.
It is used for the treatment and renovation of various floors and steps after granite, marble and artificial stone slabs are laid. It can be flexibly used with various hand grinders or renovation machines according to needs and habits.
For ceramic tile grinding and polishing, ceramic tile manufacturers are equipped with manual and automatic full polishing machines and semi-polishing machines. It is suitable for microcrystalline tiles, glazed tiles and antique tiles, full polishing and semi-polishing processing, glossy and matte optional, glossy surface brightness value It can be up to 90 or above; it is used for floor processing and renovation of microcrystalline tiles and various types of tile paving, and can be flexibly used with various hand grinders or renovation machines according to needs and habits.
It is used for the renovation of concrete floors such as industrial floors, warehouses, parking lots, or various aggregate hardener floors, especially the liquid hardener floor projects that are popular today. It can be flexibly matched with various hand grinders or grinders according to needs and habits. The refurbishment machine uses and selects DS grinding pads of different particle sizes for rough grinding, fine grinding and polishing.
Diamond Grinding Disc Features:
- Unique resin bond, strong grinding force.
- The polishing speed is fast and the finish is high.
- High wear resistance and long service life.
- After grinding and polishing, there will be no scratches or color on the stone (not easy to stain).
- Application of diamond grinding discs in stone overall grinding and refurbishment industry
- Commonly used particle sizes are 30#, 50#, 100#, 200#, 400#, 600#, 800#, 1000#, 1500#, 3000#, etc., generally from coarse to fine, and gradually select the grinding pad for grinding and polishing .
According to the requirements of different stone materials, various raw materials in diamond grinding discs are different, such as the content of diamond micropowder (also called tension) and its auxiliary materials, which are combined together, usually called formula.
According to the classification of stone, diamond grinding discs can also be divided into granite grinding discs and marble grinding discs. In general, marble grinding pads are easier to grind and polish. Granite discs are more difficult to grind and polish due to their hardness. There are also some special stones, such as the black series of stones are easy to fade; red granite (such as Indian red, South African red, etc.) is hard and difficult to grind and polish; series etc. For these stone materials, it is necessary to choose a targeted abrasive pad for grinding and polishing to achieve the ideal grinding and polishing effect.
Diamond grinding discs can be made into flexible grinding discs and rigid grinding discs. According to different grinding and polishing needs, it is generally recommended to use rigid grinding discs (also known as hard grinding discs) in the overall grinding of stones below 400#, such as 30#, 50#, 100# , 200#, 400#, 600#, 800#, 1000#, 1500#, 2000#, 3000# use flexible grinding wheels. In this way, the flatness of the stone can be very good, and at the same time, a good polishing effect can be achieved.
