The base material of PVC edge banding is composed of PVC resin, calcium carbonate powder and various auxiliary materials (stabilizer, DOP oil, ACR, stearic acid, carbon white powder, toner, anti-aging agent, etc.). The trimming effect of the edge band is related to the proportion of the base material.
1. PVC wood grain edge banding
It is printed with ink on PVC substrate and then cured by roller coating with UV paint.The good simulation effect of the wood grain edge banding depends on the quality of the ink. At present, the price of ink on the market ranges from 20 yuan/kg to 160 yuan/kg. If you use high-quality ink to print the edge banding, the simulation effect of the edge banding is close to that of the plate, the printing layer is rich, and the color fades indoors within three years. Not obvious. At present, the edge banding strips with rich printing layers are mainly three-color printing, followed by two-color printing and one-color printing.
Detection method: Put the edge strips printed with different inks under strong sunlight for a week, and then compare with the ones before sunlight, and you can see that the fading degree of the two edge strips is different. The abrasion resistance and transparency of the wood grain edge band are related to the quality of the UV paint. The market price of UV paint is between 50 yuan/kg and 120 yuan/kg. If the surface of the edge band is easily scratched and blurred, it is due to the use of inferior UV paint. The degree of adhesion between the edge band and the board, and the adhesion between the edge band and the hot sol depend on the quality of the adhesive.
There are certain requirements on the temperature of the bonding between the plate and the edge band. Although the temperature of the hot melt in the hot melt bucket of the edge banding machine is 200 o C - 180 o C, there is a distance of 20 cm - 30 cm between the hot melt and the bonding point of the edge banding strip after rolling the sheet. Due to the low workshop temperature and fast heat dissipation, the temperature of the bonding point between the board and the edge strip is actually below 120 o C, so the bonding effect is not ideal. At this time, if you use bad adhesive again, it will be easier to open the adhesive (current market price of adhesive: 18 yuan/kg - 50 yuan/kg). Solution: Since the board is cut from a low temperature place, the bonding effect will be affected because the temperature of the side of the board is too low, so keep the indoor temperature of the workshop above 15 o C, and add a Thermostat.
ABS resin is one of the most advanced materials in the world. The edge strips made of it are not doped with calcium carbonate. After trimming, they appear bright and smooth, and will never appear whitish. However, the market price of ABS resin is about 12,800 yuan / ton, and the production cost is relatively high, which is about 1 times higher than the price of PVC edge banding of the same specification in market promotion. Solid wood veneer finger joint edge banding is mainly used on veneer furniture. This product is pasted with non-woven fabric on the back to increase the strength of the veneer and prevent the veneer from breaking, and the finger joint length is 200 meters / roll, so it can be used continuously on the edge banding machine, improving work efficiency and trimming neatly. It solves the shortcomings of single veneer edge sealing.
3. Melamine edge banding, commonly known as paper edge banding, has the advantage of being easy to stick, not easily stretched and deformed when exposed to heat and cold, but because of its brittleness and easy to fold, it is easy to crash during furniture production and handling.
