What are the techniques for black and white decorative painting?

The black and white decorative painting is a painting method that uses black and white as a representation and has a decorative effect. In black and white decorative paintings, dots, lines and faces are used as basic decorative language. Among them, there is actually no strict demarcation between the three points of point, line and surface. The black and white decorative paintings use a variety of expressions to make the three levels of black and white gray in the picture rich, and the virtual and the real are scattered and densely arranged; the expression of the form is exaggerated or deformed or refined to make the painting have a special rhythm. ,sense of rhythm. Today, Xiaobian is also leading you to enjoy the black and white decorative painting pictures, but also to teach you some painting techniques about black and white decorative painting! How about, come together!


Black and white decorative painting picture

1. Use a pencil to sketch the draft on the prepared paper.


Note: Arrange the frame structure.


2. Use a pencil to outline the pattern in the blank section as the background pattern.


Note: Use the throw-and-drop effect to make the surface full, and also to make the pattern as the background and the main part of the picture.


3. Then you can hook it with a hook line pen.


First use the marker to hook out the main lines, and then use a neutral pen with different thickness to outline.


The process of ticking is that practice makes perfect, everything goes without saying.


If you are a master, you can use the hook line to directly extract lines of varying thickness.


4. Finally, use the color (acrylic pigment) to paint the most colorful and most important places to achieve the finishing touch.



The above is a detailed answer to the small and black decorative painting pictures. I don't know if you are satisfied with the introduction of the decoration home network Xiaobian~ If you want to know more about the black and white decorative painting pictures , please continue to pay attention.

The definition and classification of engineering plastics is a specific name.Engineering plastics broadly refers to plastic which has high performance and may replace metal materials.The narrow sense refers to the strength and heat resistance of plastic (PE, PP, PVC, ABS, etc.), which can be used as a structural material for industrial use and has the functional structure of high performance plastic

Plastic can be divided into two main categories: thermoplastic (after heating and melting) and thermosetting (after heating and turning into a three-dimensional structure).Engineering plastics can also be divided into special engineering plastics and standardengineering plastics.

The so-called  engineering plastics plastics often refer to thermoplastic polyamide (PA plastics).Polyoxymethylene (POM plastics), polycarbonate (PC plastics) and so on , and special engineering plastics often refers to other than the above five kinds of more excellent performance engineering plastics.According to the using temperature points, generally use temperature at 150 ℃.The following is a standard engineering plastics (generally is 100 ℃--150 ℃), more than 150 ℃ for special engineering plastics, special engineering plastics is divided into 150 --250 ℃ class (including the standardengineering plastic compounds) and above 250 ℃.The higher the temperature, the higher the price.

 

Characteristics of engineering plastics(compared with metal materials):

1.Advantages:

(a) small proportion: 1.0 -- 2.0, about one sixth of iron, reducing the weight effect;

(b) good processing and high production efficiency;

(c) water resistance and chemical corrosion;

(d) the friction coefficient

(e) can be colored freely;

(f) easy to compound with Glass Fiber and various filler;

(g) excellent electrical insulation;

(h) excellent heat insulation, with thermal conductivity of about 1% of iron and less than two thousandths of copper;

(I) reduce costs, save resources and energy.

2.Disadvantages:

(a) low heat resistance and low softening point;

(b) the mechanical strength is low and the tensile strength is generally about one-tenth of the steel;

(c) the dimension stability is poor and the linear expansion coefficient is about five times that of steel;

(d) poor durability. Prolonged exposure to gravity is susceptible to fatigue, and prolonged exposure to ultraviolet radiation is associated with lower performance.

 

3. Application of engineering plastics

(a)One is the functional components of strength, drug resistance, abrasion resistance and other requirements.The other is mechanical parts with shrinkage, dimension accuracy and appearance.Generally speaking: the former is crystalline engineering plastics, the latter is non-crystalline engineering plastics.The practical application often requires the performance of both.Engineering plastics with glass fiber (GF) or carbon fiber (CF) are more suitable for such requirements.

(b). More than half of the applications in engineering plastics are automotive and electronic, while the main use of standard plastics is extrusion molding (51%) and non-industrial products (21%).
