The Problem of Process of Thermal Transfer Texture on Metal Surface
Types
of computer desks:
1.artificial board (medium density fibreboard =MDF)
The MDF is used as the base material, and
the natural veneer is pasted on the positive and negative surfaces, generally
with a thickness of 20-60s. And then spray more layers of paint on its surface.
The main advantage of this kind of paint board is that the limitation of
furniture modeling is not big, and it can be used to make some irregular shapes
such as skew and curved surface. Melamine board tends to make simple and
fashionable products. The price is relatively low.
2. solid wood panels
Particleboard is mainly used as the base
material, and a layer of melamine paper is pasted on the positive and negative
surfaces. The industry is short for melamine board. Since the essence of its
surface is a layer of paper, it can be designed into numerous colors and
printed. For example, wood grain, cloth grain, concrete marble grain and so on.
Of course, we can also design designs that do not exist in the natural world.
In the picture, the application of the working position should be melamine
board, and the desktop is plain white. The edge of the plate is generally
sealed with PVC material.
The surface of the substrate to be transferred originally had spots or haze.
b The surface of the substrate to be transferred is not resistant to high temperatures and has a sticky or mucous membrane phenomenon.
c The spray layer on the surface of the transferred substrate is not completely cured.
d If a thermal transfer glue is used, the quality of the heat transfer glue, the ratio of the concentration, and the amount of brushing will all cause this phenomenon. Normal heat transfer glue will volatilize automatically after leaving high temperature, leaving no trace.
e If a thermal transfer glue sticking paper is used to cause this phenomenon, depending on the actual situation, it is recommended to remedy the situation that the transferred base material is scrubbed with clean water or sent to the oven for temporary baking.
f If heat transfer film is used to cause this phenomenon, it is recommended to use a low concentration of organic solvents such as acetone to scrub.
16. Is the thermal transfer product easy to discolor or discolor?
a. The quality of the base material of the transfer product will directly affect the final transfer product's transfer effect and weather resistance. When spraying powder, it is necessary to use a powder with better weather resistance, usually polyester, followed by Polyurethanes, spraying thickness of 20μm or more.
b The company selected imported printing inks, the light-fastness grades are all high-grade, usually after transfer under normal conditions, the pigment on the transfer paper or transfer film will penetrate into the surface layer of the substrate and is about 20μm deep, so it is not easy to Decolorization.
17. How to improve the thermal transfer production efficiency?
Woodgrain heat transfer paper and PET heat transfer film are different in the thermal transfer operation process and transfer equipment, the use of PET heat transfer film transfer production efficiency will be higher, and can be shaped or complex shape base Each transfer surface of the material can transfer texture.
18. What are the advantages of thermal transfer over other transfer methods?
a The thermal transfer has high production efficiency and low cost, and this advantage is more prominent than the water transfer.
bThere are few inputs and fewer operators.
19. What kind of thermal transfer paper or transfer film can be produced?
The company's wood grain decorative paper samples can not produce heat transfer paper or transfer film other than gold powder, silver powder, pearl powder, etc. Other color samples and fancy patterns can be produced.
20. How to do the customer's color adjustment?
a The customer provides a sufficient amount of toning to transfer or transfer film samples.
b Provide the customer with a substrate board that has a base color and that is consistent with large production. (Note: If the customer requests to color the transferred sample, the customer must provide the substrate sheet with the background color and the same color as the sample.)
c. It is confirmed by the company's proofing to the customer. After your confirmation, you will arrange for a big production.
