What processing method should be used to ensure the processing quality of thick melamine board (in fact, it is anti-American board or anti-β board or anti-β board-editor's note)?

What is the material of Nami board? What's the difference between it and anti-beta board and beta board?

In fact, there is no difference between American-resistant board and bite-resistant board or Binet.Alfred board. In terms of its characteristics and structure, it belongs to the same material. Anti-American board is a transliteration of Korean product Lamis. Similarly, the bite plate and Binet.Alfred plate are transliteration of product trademarks.

This material is actually a thickened melamine board, which is made of several layers of materials, such as wear-resistant surface board, decorative laminate, carbonated kraft paper board, colored striped board and so on. And processed at high temperature and high pressure. Because this kind of plate can be processed into products without edge sealing or strengthening treatment, and decorative layers can be laid in the middle at will, it is very popular with people.

This kind of plate is convenient to process because it does not need edge sealing and other treatments, and the processing time can be shortened by 50%. It is also widely used as countertops and door panels of kitchen utensils, countertops of various tables, countertops of laboratories, office partitions, bathroom partitions, etc. Because of its good machinability and physical properties, as well as good resistance to various chemical reagents and pollution-free ability.

What should I pay attention to when processing this kind of plate?

Due to the hard texture of the board, the following aspects should be paid attention to during processing:

1. When cutting, linear saw should be the main method. Usually, before sawing, specifications and dimensions can be drawn on this plate. If the size of the workpiece is standard, it is much more convenient to mark with the template before sawing.

2. When drilling, you can use a portable jigsaw to cut, and the cutting speed should be 3-4m/min. If the cutting speed is too fast, on the one hand, it will cause defects such as the bursting of the cutting edge, on the other hand, it will also affect the service life of the saw blade and increase the processing cost.

3. When machining special-shaped edges, the required size should be drawn on the surface of the plate first, and then cut with a curve saw; If mass production is carried out, the template can be used for cutting, which can ensure the processing speed and sawing quality.

4. When processing edges, the commonly used tool is a hand-held router. Before operation, the dust or foreign matter on the surface of the plate should be removed. In order to avoid leaving scratches or nicks on the surface of the plate, the processing speed of the router should be kept at 2m/min. If the blade angle of the router is small and the workpiece thickness is thick, the processing speed of the router should be slowed down appropriately. In addition, the length of the cutting edge of the milling cutter is greater than the thickness of the workpiece, so as to ensure that the edge line can be milled at one time. When feeding, the router should slide down gradually from high to low until the router edge covers the milling edge. It is worth noting that when cutting, it must be smooth and do not let the router shake. Shaking will cause irregular ripples on the edge of the workpiece, which will increase the workload for the subsequent sanding and polishing processes and affect the machining efficiency.

5. When sanding, the edges shall be sanded with 80 #, 220 # and 320 # sandpaper respectively, and the sanding speed shall be subject to the length of 2.5m,15-20min; When polishing, care should be taken not to damage the surface decoration layer. After polishing, the edge should be polished with polishing agent, and artificial marble can be used to polish wax. The polishing procedure is as follows:

A. Wipe the edge with a soft cotton cloth dipped in a proper amount of polishing wax;

B. When the polishing wax is dry, coat a layer of polishing wax on the edge and wipe it with a cloth to make it shiny. Finally, apply a layer of polishing wax and wipe it with a clean cloth until the edge is bright.

6. When splicing plates, you should master the following points:

A. The coating amount of adhesive should be controlled at 2.5-3.0g/cm2; The bonding surface shall be completely coated;

B. After splicing, clamp for about 30 minutes. When bonding in the vertical direction, be sure to open the mouth to increase the bonding surface to ensure the bonding strength;

C. Once defects such as bursting are found in the bonding part, the smooth and flat side should be turned outwards to ensure the bonding quality.

7. If you want to connect the products with screws, you should first drill a small hole with a drill with a smaller diameter than the screws, then inject adhesive into the small hole, and then screw in the screws, and ensure that the upper edge of the screw profile is screwed in more than 5 mm.

8. When drilling an elbow with a dark cup hole, the remaining thickness of the plate should be at least 3 mm If the remaining thickness is too thin, the cup hinge will be damaged or raised after being buried. When installing the hidden chain, the bottom of the hole and the fixing screw hole should be coated with glue and then tightened with screws. When tightening the screw, don't use too much force, otherwise the edge of the plate will also protrude, and it will burst in severe cases.

9. After installation, if there are spots or stains on the surface, you can gently wipe them with a towel dipped in a small amount of oily cleaner (a mixture of oil and acetone) to remove them. If there are no spots or stains, you can wipe them with soap, detergent and other general cleaners.
