Briefly talk about the main use of acrylic products
In daily life, we often use the finished products made of acrylic, so its main purpose, advantages and disadvantages are clear? Let's take a look at the following experts from the acrylic industry.
PMMA is a polymer obtained by polymerizing acrylic acid and its esters, collectively referred to as acrylic resin. The corresponding plastics are collectively referred to as polyacrylic plastics, of which polymethyl methacrylate is the most widely used. Polymethyl methacrylate, abbreviated as PMMA, commonly known as plexiglass, is by far the most excellent synthetic transparent material.
PMMA has the advantages of light weight, low cost and easy molding. Its forming methods include casting, injection molding, machining, and thermoforming. In particular, injection molding can be mass-produced, with simple process and low cost. Therefore, its application is increasingly widespread, it is widely used in instrumentation parts, automotive lights, optical lenses, transparent pipes and so on.
Because acrylic production is difficult and costly, there are many low-cost and low-cost substitutes on the market. These substitutes are also known as "acrylic" and are actually ordinary organic boards or composite boards (also known as sandwich panels). Ordinary organic plates are cast with ordinary plexiglass cracking materials and pigments. The surface hardness is low and easy to fade. After polishing with fine sand, the polishing effect is poor. The composite board has only a thin layer of acrylic on the surface, and the middle is ABS plastic, which is easily delaminated by the expansion and contraction during use. True and false acrylic, which can be identified from the subtle chromatic aberration and polishing effect of the sheet section
Acrylic is the best new material that can be used to make sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic has the following advantages in addition to unparalleled high brightness: good toughness and not easy to break; strong repairability, as long as you use soft foam to remove toothpaste, you can wipe the sanitary ware; soft texture, winter There is no feeling of cold and biting; the color is bright, which can satisfy the individual pursuit of different tastes. Acrylic basins, bathtubs, and toilets are not only beautiful in style, durable, but also environmentally friendly. The radiation level of the human body is almost the same as that of the human body. Acrylic sanitary ware first appeared in the United States and has occupied more than 70% of the entire international market.
