Acrylic sheet is a kind of plastic material, which is easy to process and makes beautiful and exquisite products.
Generally speaking, they are mainly divided into two categories:
Machining
2 thermoforming processing
A machining process uses tools to cut, drill, plan, engrave, grind, polish, etc. the tools used are also very simple. All machines used for processing wood and lightweight metals (such as aluminum and copper) can be used to select the tool selection and motor speed. In general, carbonized knives and sharper tools are required, and the required motor speed is also high.
Two thermoforming processing thermoforming: Acrylic sheet is a thermoplastic plastic material, so it can be heated to soften and reshape the shape required. The oven or the electric heater can soften the acrylic sheet, and the heating temperature is between 150 and 200 ° C, and then placed on the mold to be formed, and then cooled. In addition, it can also be used for stretch forming, generally using a mold, and then applying hot pressing, vacuum or plastic forming.
Acrylic sheet gluing: Acrylic sheets can be glued with a general solvent such as chloroform, methylene chloride or Krebs adhesive. When in use, the solvent is injected into the glue joint with a syringe, and then left to stand for a few minutes to be fixed and glued.
Acrylic, also known as plexiglass, formerly known as methyl propyl vinegar resin sheet, is easy to customize for different shapes and is suitable for applications requiring high sensitivity, such as lenses implanted in heart valves, contact lenses or cameras. Common to aircraft cabs, crash helmets or skylights. It is no wonder that it is widely used in bathing environments where hygiene, safety and aesthetics are requested.
Features: light weight, specific gravity between 1.19-1.20g /.
Transparency exceeds ordinary glass, with 93% light transmission and crystal glass brilliance. (Discoloration time: it turns yellow in 2 years)
Acrylic passes through thermoforming, and the forming temperature of the sheet is between 150 ° C and 160 ° C. The surface hardness of the acrylic sheet is equivalent to aluminum, which is harder than Other plastics but cannot withstand iron. The ceramics are hard and frictional.
Usually the shower room is made of tempered glass.
Usually, the glass used in the shower room is a tempered glass that has been processed by physical means, that is, a process in which the glass is heated to a certain temperature and then suddenly cooled. The tempered glass changes the crystal structure inside the glass and improves the surface hardness. The impact resistance and bending strength of the glass are 3-5 times higher than that of ordinary glass. When damaged by external force, the glass is small fragments without sharp angles, and the degree of damage to the human body is significantly reduced.
Acrylic is a transliteration of the English "Acrylics". In the chemical sense, Acrylics is acrylic acid and its derivatives and methyl methacrylate (also known as methyl methacrylate in China) or methacrylic acid ( A generic term for methacrylic acid and its derivatives. At present, the term "acrylic" in Chinese refers to various products made of methyl methacrylate or methacrylic acid and its derivatives. Acrylic products commonly heard in the market include acrylic sheets, acrylic plastic pellets, acrylic light boxes, signboards, acrylic bathtubs, acrylic artificial marbles, acrylic resins, acrylic (lacquer) paints, etc., and a wide variety. In fact, the acrylic products commonly found in the market are made of acrylic pellets, plates or resins and other raw materials, and assembled with various materials and functional parts. Products. The application of various acrylic products is quite extensive, and this website has a detailed introduction. Acrylic fiber, acrylic cotton, acrylic yarn, acrylic dragon, etc., which are commonly heard, refer to man-made fibers polymerized from propylene, and are not related to acrylic products. The following illustrations briefly illustrate the process by which acrylic is made from a variety of acrylic materials from upstream materials and then processed into a variety of acrylic products from acrylic materials: the acrylic sheet is often referred to as polymethyl methacrylate Polymeric Methyl Methacrylate ( PMMA) sheet, which is polymerized from Methyl Methacrylate (MMA). Or it is made from acrylic pellets by a slab. In the past, acrylic sheets were commonly known as "plexiglass" in mainland China. "Plexiglas" is derived from English Organic Glass, which means a PMMA board made of organic compound MMA, which has transparency and transparency like glass. However, in recent years, all the sheets made of transparent plastics such as PS, PC, etc. or by inferior recycled MMA have been collectively referred to as "plexiglass". For the sake of separation, the PMMA board made of high-quality pure material MMA will be called "acrylic board" or "acrylic board" to distinguish it from ordinary plexiglass board.
