First, the main components of quartz stone: quartz stone = 90% quartz sand (powder) + 10% resin. Quartz stone and ordinary artificial stone have a big difference, quartz stone is 90% natural quartz, so the character is closer to natural stone, It has the characteristics of hard and toughness of natural stone, and its hardness is higher than that of natural marble, so in addition to making a countertop, paving the floor is also a bright spot.
two. The current processing status is due to the large difference in hardness and toughness between quartz stone and ordinary artificial stone. Therefore, the processing method is also quite different from ordinary artificial stone. However, the current understanding shows that the quartz stone processing method and process, There are some misunderstandings in some details, and some only process the processing methods and techniques of ordinary artificial stone to process quartz stone plates. As a quartz stone manufacturer, it is necessary and responsible to provide some guidance for the quartz stone processing method for the cabinet factory processing workshop and quartz stone agent for reference.
Third, the processing requirements of quartz stone, in principle, is the same as the processing of natural stone. Operators who process quartz stone preferably have experience in processing natural stone. Operators who have experience in processing general-purpose artificial stone but have no experience in processing natural stone must, in principle, be trained before they can be employed. Common processing tools: necessary tools 1. Multi-functional marble cutting machine (cutting and cutting, chamfering); 2. Grinding machine (with special diamond grinding disc, resin grinding disc); 3. Cantilever water grinder polishing machine; 4. Hand drill (with diamond sleeve drill R15-R45 mm); 5. Curve according to small blades, triangular glass fixtures, wiring sockets, etc. Special materials are: (1) marble glue (white, transparent); (2) quartz stone special glue (factory preparation); (3) quartz stone special dry glue (factory preparation); (4) curing agent.
Fourth, the processing process: field measurement drawing and record size → confirm the color of the table, the edge type → draw the drawing according to the drawing, draw the line → cut with the marble machine → use the multi-function marble machine or other special water mill to sharpen the edge Type→Blow dry clean glue water→Adjust glue water, apply adhesive surface→Clamp with special fixture→Cure and use scraper to remove waste glue with special grinding and polishing machine → Polishing → Check positive size. Back reinforcement. Grinding and chamfering with hard diamond water grinding tablets, first 50#, after 150#, then 300#; when polishing, start to use 500# water grinding tablets, and then use 1000#, 2000#, 3000# water grinding tablets in sequence polishing. Note that diamond water-polished sheets must be hard. The size of the water-grinding piece is 3 or 4 inches, depending on the needs of use. The connection must be connected with a 45 degree diagonal port. Cutting must use a hard diamond saw blade with high hardness and high sales volume, and cut it under water cooling. The saw blade should rotate at 6000 rev/rev. Saw blades with insufficient corundum content may cause cracking of quartz stone sheets by high-speed impact due to insufficient cutting sales, and the saw blades are not durable. The high-hardness diamond saw blade used must have a sand outlet or a sand outlet hole, so as to prevent the quartz stone crushed sand from being discharged in time to cause local heat generation to cause the quartz stone plate to crack during processing.
5. Opening the furnace hole: 1. According to the design requirements, determine the center position of the basin hole, the distance between the furnace hole side and the rear water blocking edge is not less than 70mm; 2. When opening the furnace hole, the hole must be punched at the four corners of the furnace hole (perforated The drill bit must be a high-hardness diamond drill bit, which is available in Yunfu's stone processing tool supplies store. Then use a wire cutter to cut the square slowly and evenly. When cutting, you can not cut the plate at one time. It should be cut in two steps. The first step is to cut 1/3 of the thickness of the sheet. In the second step, the sheet is cut through to prevent the sheet from cracking. 3. When opening the furnace hole, the bottom of the quartz stone plate should have a backing plate, which can not be completely suspended, and the bearing force should be uniform to prevent cracking during the opening process due to uneven force. 4. After the furnace hole is cut into squares, the corners of the angle of the angle grinder are ground into a circular arc angle. The radius of the arc is not less than R10mm. The back of the four corners of the furnace hole is thickened with a small plate of about 120×120mm, and then grinded by an angle grinder. Into the corresponding arc, the four sides are thickened with a quartz stone plate with a width of 30mm or more.
6. The glue quartz stone that can be used in the bonding of quartz stone can be used in the same way as the glue used in natural stone. (1) Marble glue. Yunfu is available for sale and is most commonly used. The specific use must be carried out in accordance with the requirements in the instruction manual. (2) Special glue for quartz stone. Quartz stone factory preparation, must be used to ensure that the interface is dry, oil-free and wax-free. If you are not sure, use acetone or Tianna water to clean it. After the cold is dry, the bonding work can be carried out. The connection port of quartz stone is preferably 45 degree oblique port connection, and the connection port must be roughened. This glue cures in 15 minutes, but the true ripening is one week later and can be fully fitted (chimeric) to the quartz after one month. (3) Special dry glue for quartz stone. Quartz stone factory is prepared, using the same glue as quartz stone, but the difference between wet and dry is different. (4) Epoxy AB type dry hanging glue. Yunfu Stone Shop is available for sale. Use it according to the instructions. In short, the processing technology of quartz stone is the same as that of natural stone. The processing methods and tools are the same as those of natural stone. The processing technology of general artificial stone cannot be transplanted to quartz stone.
Quartz stone is a new generation of nano anti-fouling, non-radiative, quartz artificial stone based on natural quartz sand and quartz powder. Compared with the cast-in-place resin artificial stone, acrylic sheet, calcium powder and other series of artificial stone in the countertop industry, the advantages of hardness, wear resistance and antifouling performance are more prominent.
