The materials for lamp shades include: 1. Fabric lamp shades; 2. PVC lamp shades; 3. Kraft paper lamp shades; 4. PC lamp shades; 5. Glass lamp shades; 6. Plastic lamp shades; 7. Acrylic lamp shades. The most commonly used materials for lamp shades are PC lamp shades, acrylic lamp shades, fabric lamp shades, and glass lamp shades. Fabric lamp shades give an impression of simplicity and elegance, while paper lamp shades create a soft, dreamy atmosphere. Metal lamp shades have a modern look and are better suited for cool color schemes. The drum-shaped lamp shade evokes a nostalgic feeling; moreover, depending on the location, in the bedroom we can choose ones made of silk, as the handmade and hand-painted effects are better. It can create a very soft and intimate atmosphere in a room; for the living room, linen or parchment materials can be chosen. However, glass lamp shades are quite fragile, which is a downside; they are not easy to move. Acrylic and PC lamp shades are materials that are widely used nowadays; they not only possess excellent properties but also serve a great decorative purpose. The advantages of glass are ； Does not fade, resistant to scratches, and easy to clean. The downside is ； Too heavy, fragile. The glass craftsmanship is relatively inferior. The advantages of resin are ； Light, unbreakable, and less susceptible to scratches compared to acrylic. Disadvantages ； Color change, deformation at high temperatures over extended periods. The advantages of Yakli ； Light, highly transparent, and not easy to break. The downside is ； Not scratch-resistant. Generally, the cover materials for LED ceiling lights include plexiglass, leather, plastic, etc. There are three common materials used for ceiling light covers nowadays: acrylic, PC, and PVC. All three of these are widely used these days. Generally speaking, the PC option is the best; acrylic has good light transmittance but is very fragile.
Acrylic, also known as PMMA or Acrylite, derives from the English word acrylic (an acrylic plastic). Its chemical name is polymethyl methacrylate; it is an important plastic polymer material that was developed quite early on. It boasts good transparency, chemical stability, and weather resistance, is easy to dye and process, and has an attractive appearance, making it widely used in the construction industry. Acrylic products can generally be divided into cast sheets, extruded sheets, and molded plastics. Common acrylic products are made by using raw materials such as acrylic granules, sheets, or resin, and by applying various processing methods; they are then assembled with accessories of different materials and functions. As for the terms commonly heard such as acrylic fiber, acrylic cotton, acrylic yarn, and acrylic nylon, they refer to synthetic fibers made by polymerizing acrylic acid, and have no connection with acrylic products. The acrylic sheet commonly referred to is actually Polymeric Methyl Methacrylate (PMMA) sheet, which is formed by the polymerization of Methyl Methacrylate monomer. Or it is made by extruding acrylic pellets through an extruder. In the past, this material was commonly known as plexiglass. Acrylic comes from the English word “acrylic,” referring to PMMA sheets made from the organic compound MMA, which have transparency and light transmittance similar to that of glass. All sheets made of transparent plastics such as PS and PC, or from low-quality recycled MMA, are collectively referred to as plexiglass. For the purpose of differentiation, PMMA sheets made from high-quality pure MMA are uniformly referred to as acrylic sheets, in order to distinguish them from ordinary plexiglass sheets.
New application areas for acrylic: Acrylic furniture. Acrylic furniture first appeared in Europe and began to develop in the 1990s; it was not until the 21st century that this type of furniture saw significant progress. In high-end hotels and villas, acrylic furniture can be found, contributing to a beautiful and classic aesthetic in home decoration. Since Rohm & Haas in Germany produced the first acrylic sheet in 1920, the use of acrylic has become increasingly widespread. Acrylic furniture first appeared in Germany. In 1941, a designer at a German craft company had an idea while creating decorations: it would be perfect to use acrylic as a material for furniture. He then designed a blueprint for a coffee table made of acrylic, and three days later the coffee table was created. It had the perfect appearance as he had envisioned, though its structural design was somewhat lacking. Thus, acrylic furniture was born. Acrylic can also be used to make eco-friendly buttons. Due to its high light transmittance, the buttons made from it shine brightly. At the same time, due to its high hardness and resistance to breaking, it can be used for a long time. Most furniture available on the market is made from traditional materials such as wood, metal, and glass. Furniture made from these materials has issues such as high costs, environmental unsustainability, and complex manufacturing processes.
I’ve heard of human skin lanterns; I’m not sure if they only exist in movies.
I am truly impressed by your imagination! Feel free to provide clues for science popularization – the polymer-themed events are here to serve you and all fellow enthusiasts with utmost dedication!
Hehe, there’s nothing to do; my mind can’t stay focused and just wanders around. @dlutyj
I’ve learned a lot; I really didn’t notice the materials used in these everyday products before
