Who knows the art of wood on the brush is what oil?
Second, explain:
1, on the role of tung oil:
Tung oil is the picking of the tung tree fruit by mechanical crushing, processing and refining made of tung oil industrial vegetable oil, the whole process for the physical method. Tung trees are perennial woody trees that grow in mountains far from the city. Resistant to pests and diseases particularly strong, the whole process of growth without fertilization and pesticides. Tung oil is a natural vegetable oil, it has a rapid drying, high temperature, corrosion resistance and so on. Tung oil also has a good waterproof, widely used in construction, paint, printing (ink), agricultural machinery, electronics and other industries.
First, simply answer as follows:
The first layer is tung oil, not paint, the role of tung oil should be anti-corrosion, the outside layer is a varnish, varnish role is smooth and bright.
2, on the role of varnish analysis:

[Apply to the surface of the object, the formation of a protective, decorative and special properties of the coating, dry after the formation of smooth film, showing the original pattern of the surface. To
Varnish as home decoration in the scene of the construction of the most important lacquer is a unique reason. Polyester paint for the construction environment and construction process requirements are high, and varnish is not. In the process of brushing the flow often occurs in the sagging (tears), for example, polyester paint in the process of forming the sagging process is difficult to re-dissolve solidification, and varnish smoothness is good, there is sagging also It does not matter, then brush it again, sagging can be re-dissolved.
