ã€ALUMINIUM NETWORK】The woodgrain transfer profile refers to the wood grain pattern on the transfer paper or the transfer film through heating or pressing according to the principle of sublimation heat penetration on the basis of powder spraying or electrophoretic painting. , Quickly transfer and penetrate into the already sprayed or electrophoresis. Make the production of wood grain texture clear, three-dimensional sense, better reflect the natural feeling of wood grain, is an ideal energy-saving and environmentally friendly material to replace the traditional wood.
Wood grain has a strong adhesion to aluminum, non-toxic, no odor, easy to clean. Product lines are clear and realistic, three-dimensional sense, appearance and decorative effect is good, there are back to nature, return to nature's visual effects. Spray coating on the surface of aluminum profiles is non-volatile, non-oxidizing and does not pollute the environment. The dirt deposited on the sprayed surface, once cleaned, can restore its original luster and appearance.
Here is a detailed description of the process of woodgrain transfer. Process 1: Suitable for large area or profiled substrates. Rely on the previous step: Select substrates that have been sprayed or electrophoresed. Step 2: Transfer with woodgrain thermal transfer paper. The substrate is wrapped and the paper interface is secured with a high temperature adhesive tape to prevent the woodgrain transfer paper from loosening. (Note: The front of the woodgrain transfer paper must be attached to the surface of the transferred substrate.)
Step 3: Put a plastic plastic bag with high temperature resistance and good tightness on the substrate that has been wrapped with woodgrain thermal transfer paper, and then pull the vacuum from both ends of the plastic plastic bag until the plastic plastic bag can Adhere to the substrate fully and effectively. The vacuum negative pressure should be properly adjusted according to the characteristics of the substrate to be transferred and the negative pressure that plastic plastic bags can withstand, usually between 0.3 and 0.8 Mpa. (Note: The purpose of using plastic bags is to force the wood-grained thermal transfer paper that has adhered to the substrate to fully and effectively adhere to the substrate by means of negative pressure.)
Step 4: The wrapped substrate is sent to the oven for baking. The baking temperature and length of time should be based on the characteristics of the transferred substrate, the depth of texture to be transferred, and the specific properties of the oven. Make appropriate adjustments, usually the transfer temperature is 160 ~ 180 °C, time is 5 ~ 8 minutes The fifth step: remove the substrate has been transferred from the oven, pull the plastic bag from the end of the substrate being transferred (Note: This plastic plastic bag can be profitably reused), tear off the thermal transfer paper, and do the surface cleaning process II: apply to the flat substrate by the previous step: Select the substrate that has been sprayed or electrophoresed. Step 2: The front of the woodgrain thermal transfer paper and the surface of the substrate to be transferred to the third step: plate heat transfer press, heating, usually the transfer temperature is 160 ~ 180 °C, time is 18 ~ 25 seconds Four Steps: Tear off the heat transfer paper, use the PET heat transfer film transfer: apply to the shaped substrate Step 5: Wrap the transferred substrate with a PET heat transfer film, use an ultrasonic sealer to turn the PET The heat transfer film is sealed into a tubular bag. (Note: The front surface of the PET heat transfer film must be attached to the transferred surface of the transferred substrate.)
Step 6: Vacuum from both ends of the tubular PET heat transfer film bag until the PET thermal transfer film is fully and effectively attached to the substrate. The vacuum negative pressure should be properly adjusted according to the characteristics of the substrate to be transferred and the negative pressure that the PET heat transfer film can withstand, usually between 0.3 and 0.8 Mpa. Step 7: The already wrapped base When the material is sent to the oven for baking, the baking temperature and length of time should be properly adjusted according to the characteristics of the substrate to be transferred, the depth of texture to be transferred, and the specific properties of the oven. Usually the temperature of the transfer is 160 ~ 180 °C, time is 5 ~ 8 minutes The eighth step: remove the substrate has been transferred from the oven, using manual or mechanical blowing (that is, blowing the PET heat transfer film tubular bag blown ) The way to remove PET heat transfer film
