What are acrylic lenses? What are the characteristics and uses?
Acrylic lenses actually refer to PMMA plates after electroplating. Using plastic lenses instead of glass lenses has the advantages of light weight, not easy to break, convenient molding and processing, and easy coloring. The development momentum of acrylic lenses is increasing and has become a technology in lens production. Generally, plastic sheets can be made into single lens, double lens, rubber lens, paper lens, half lens, etc. They can be manufactured according to different requirements, such as the screens of mobile phones and televisions, which can be seen every day. Acrylic lens characteristics: Acrylic is suitable for secondary processing, such as mechanical processing, thermoplastic molding, blow molding, blister molding, solvent bonding, thermal transfer printing, screen printing, vacuum deposition. After success, it is what we call acrylic lenses. Acrylic board is polymerized from methyl methacrylate monomer (MMA), which is also known as polymethyl methacrylate (PMMA) board organic glass. It is a type of organic glass processed through special processes and is known as the "queen of plastics". The research and development of acrylic has a history of over 100 years. Acrylic lens usage: Acrylic has the advantages of light weight, low price, and easy molding. Its molding methods include casting, injection molding, mechanical processing, acrylic hot molding, etc., especially injection molding, which can be produced in large quantities with simple process and low cost. Therefore, its application is becoming increasingly widespread, currently widely used in instrument parts, car lights, optical lenses, transparent pipes, and so on. Acrylic is an ideal new material for manufacturing sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic not only has different high brightness, but also has the following advantages: good toughness, not easily damaged; Strong repairability, as long as the soft foam is dipped in toothpaste, the sanitary ware can be wiped clean; The texture is soft, and there is no cold and piercing feeling in winter; Bright colors can meet personal pursuits of different flavors. Acrylic material washbasins, bathtubs, and toilets are not only exquisitely designed and durable, but also have environmental protection functions, with radiation lines almost identical to human bones. Acrylic sanitary ware first appeared in the United States and now accounts for over 70% of the international market. Due to the difficulty and high cost of acrylic fiber production, many low-quality and low-cost alternatives have emerged in the market. These substitutes, also known as "acrylic", are actually ordinary organic or composite boards. Ordinary organic board is made by casting ordinary organic glass cracking material and pigment, with low surface hardness and easy fading, and poor polishing effect after polishing with fine sand. In the middle, there is only a thin layer of acrylic on the surface of the composite plate of ABS plastic, which is easy to delaminate due to the influence of thermal expansion in use. Acrylic lenses can be distinguished by the subtle color difference and polishing effect of the plate: 1. Architectural applications: windows, soundproof doors and windows, daylighting covers, telephone booths, decorative colored mirrors, etc. 2. Advertising applications: 3360 lightboxes, signs, signs, exhibition stands, etc. 3. Transportation applications: trains, car mirrors, car lenses, etc. 4. Medical applications: baby care boxes, various surgical and medical devices, civilian products: handicrafts. Aquarium, toy mirror, etc. 5. Industrial applications: instrument panels, protective covers, etc. 6. Lighting applications: fluorescent lamps, chandeliers, street lamp lampshades, LED reflective panels, acrylic reflective panels, etc.
