PVC wood grain edge banding
It is printed with ink on the PVC substrate and then rolled with UV paint and cured.
The quality of ink is good for wood grain edge banding to show a good simulation effect. The price of ink on the market now ranges from 20 yuan/kg to 160 yuan/kg. If the edge banding is printed with high-quality ink, the simulation effect of the edge banding is close to that of the board, the printing is rich in layers, and the indoor fading is not obvious within three years. At present, the edge banding with rich printing layers is mainly three-color printing, followed by two-color printing and one-color printing.
Detection method: Place the edge banding printed with different inks under strong sunlight for a week, and then compare it with before sunlight exposure, you can see that the fading degree of the two edge bandings is different. The wear resistance and transparency of wood grain edge banding are closely related to the quality of UV paint. The market price of UV paint is between 50 yuan/kg and 120 yuan/kg. If the surface of the edge banding is easily scratched and blurred, it is due to the use of inferior UV paint. The degree of adhesion between the edge banding and the board, and the bonding effect between the edge banding and the hot melt depend on the quality of the adhesive.
The bonding between the board and the edge banding has certain requirements on temperature. Although the temperature of the hot melt in the hot melt barrel of the edge banding machine is 200 o C-180 o C, there is a distance of 20CM-30CM between the hot melt and the bonding point of the edge banding after the hot melt is rolled on the board. Due to the low temperature in the workshop and the fast heat dissipation, the temperature of the bonding point between the board and the edge banding is actually below 120 o C, so the bonding effect is not ideal. At this time, if a bad adhesive is used, it is easier to open the glue (the current market price of the adhesive is: 18 yuan/kg-50 yuan/kg). Solution: Because the temperature of the side of the board will be too low and affect the bonding effect if the board is brought from a low temperature place for cutting and sawing, so the indoor temperature of the workshop should be kept above 15 o C and a constant temperature cover should be added to the edge banding machine edge banding disk.
