The basic requirements that decorative materials should meet (1) The color of a color material is determined by three aspects: spectral reflection of the material, the spectral composition of the material that strikes the material when viewed, and the spectral sensitivity of the viewer's eye. So the color is not inherent to the material itself, it involves physics, physiology and psychology. For physics, color is light energy; for psychology, color is sensation; for physiology, color is the link between the ocular nerve and brain cells. The person's mental state will reflect his feelings about color. Most people will react strongly to the uncoordinated combination of colors. The proper color selection and coordination of color combinations can create a beautiful work and living environment. Therefore, color is extremely important for decorative materials. The resolution of the same color cannot be exactly the same, so a spectrophotometer should be used to measure the color objectively and scientifically.
(2) Glossiness Gloss is a property of a material's surface that is second only to color when assessing decorative materials. Light strikes an object and part of the light is reflected. The reflected light can be dispersed in all aspects to form diffuse reflections. If the concentrated reflections are formed as specular reflections, specular reflection is the main factor for gloss. Therefore, luster is a directional light reflection, which plays a decisive role in the clarity of the image formed on the surface of an object, ie, the strength of reflected light. The same color can appear bright and dull, which is related to the surface gloss. The electro-optic gloss meter is used to determine the gloss of the material surface.
(3) Transparency The transparency of a material is also a property related to light. Objects that can both transmit light and see through are called transparent bodies; objects that can only transmit light but cannot be seen through are translucent bodies; objects that cannot transmit light and cannot be seen through are opaque bodies (4) The surface structure and shape dimensions are due to decorative materials. The different raw materials, production processes and processing methods used make the surface structure of the material have a variety of characteristics: fine or rough, solid or loose, flat or uneven, and so on, so different materials even The same material also produces different textures, and different textures can cause people to feel differently. For decorative materials such as boards, boards, and coils, all require certain specifications and come in various shapes and sizes so that they can be assembled into a variety of patterns and patterns. There are also specific specifications for the natural patterns (such as natural stone), textures (such as wood) or artificial patterns and patterns (such as wallpaper) on the surface of various decorative materials.
(5) Three-dimensional modeling For prefabricated decorative floral ornaments and sculpture products, it has a certain three-dimensional shape. In addition to the above requirements, the decorative materials should also meet the requirements of strength, water resistance, corrosion resistance, fire resistance, non-staining, and discoloration, so as to ensure that the decorative materials can maintain its characteristics over a long period of time.
