Acrylic and ceramics have different characteristics, different people have different feelings, and vary from person to person.
One, acrylic, also known as PMMA or Asia, is derived from English acrylic (acrylic acid). The chemical name is polymethyl methacrylate. It is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weatherability, easy dyeing, easy processing and beautiful appearance.
1, with crystal transparency, transmittance of more than 92%, light and soft, clear vision, acrylic dyed with dyes and good color development effect.
2, acrylic board has excellent weatherability, high surface hardness and surface gloss, and good high temperature performance.
3, acrylic board has good processability, not only by hot forming, but also by mechanical processing.
4. Transparent acrylic plate has the transmittance comparable to glass, but the density is only half that of glass. Besides, it is not so fragile as glass, even if it breaks down, it will not create sharp fragments like glass.
5. The abrasion resistance of acrylic board is close to aluminum material, good stability and corrosion resistance of various chemicals.
6, the acrylic board has good printing and spraying properties, and the appropriate printing and spraying process can give the ideal surface decoration effect of acrylic products.
7, fire resistance: non spontaneous combustion but inflammable, not self extinguishing.
Two. The utensils made of pottery clay are called pottery, and the utensils made of porcelain clay are called porcelain. Ceramics are the general names of pottery, stoneware and porcelain. All the two kinds of clay, which are made of clay and porcelain clay, are made of clay as raw materials. The utensils made of ingredients, molding, drying and baking can be called ceramics.
Ceramic material: compared with porcelain, the texture of pottery is relatively loose and coarser. The burning temperature is generally between 900 and 1500 degrees C, and the temperature is low. After burning, the color and lustre are natural, simple and simple, and become one of the modeling materials that many artists love. There are many kinds of pottery, such as black pottery, white pottery, red pottery, grey pottery and yellow pottery. Red pottery, gray pottery and black pottery are used as raw materials. The iron clay is red under the atmosphere of oxidation, and it is gray or black under the atmosphere of reduction.
Porcelain material: compared with pottery, porcelain is hard, dense, strictly forbidden, high temperature resistant and rich in glaze. The temperature is usually about 1300 degrees centigrade. It is often described as "chime like chime, bright like mirror, Yan as jade, thin as paper", and porcelain is more noble and magnificent than that of pottery. Therefore, in the creation of ceramic art, many artists will highlight the different sensory enjoyment of the texture of pottery or porcelain to the appreciating. Therefore, it is necessary to analyze and compare the characteristics of the two different materials before the creation.
