With the popularity of acrylic, many people are not particularly clear about the difference between PC board and acrylic board in their daily lives. So today, the editor will briefly introduce the differences between acrylic and PC boards to everyone.   1. Materials The basic raw materials of acrylic sheets and PC sheets are different. Acrylic is formed by polymerizing methyl methacrylate monomers (MMA) of acrylic acid. PC sheets are primarily composed of polycarbonate and are produced using co-extrusion technology.   2. Appearance Both acrylic panels and PC panels have good light transmittance. The light transmittance of acrylic panels is above 92%, and the light transmittance of PC panels can reach up to 89%. It is difficult to distinguish them based on this facto.   3. Combustion According to the standard GB 50222-95 of my home, PC boards cannot burn when exposed to fire. Their self-ignition point is 580℃, and they will self-extinguish after being removed from the fire. Therefore, no toxic gases will be produced during combustion, and it will not promote the spread of fire. When acrylic burns, the flame is clear, without smoke or bubbles, and the filament can be pulled out when extinguishing. When casting boards burn, there is no smoke, no bubbles, and no sizzling sound, and there is no filament when extinguishing.   4. Impact resistance PC boards have good impact resistance and are not easy to break when dropped. The impact resistance of PC boards is 8 to 10 times that of acrylic boards.   5.K UV The kang ultraviolet capacity on the surface of the pc is 5 times that of outdoor acrylic acid. Generally, the service life of acrylic board can reach 2 years without yellowing, and PC board can reach 10 years.   6. Price Compared with acrylic board, PC board is more expensive than acrylic board. For example, the price of 3MM thick PC board per square meter is about 195 yuan; The price of 5MM thick acrylic plate in the same area is about 265 yuan. Acrylic plates and acrylic lenses are widely used in TV displays, lighting, crafts, exhibition and exhibition, transportation facilities, advertising, furniture and other fields.

With various prices in the market, it's common to have doubts. The appearance of transparent acrylic sheets is similar, so how to choose? In response to this question, I will introduce some tips for purchasing transparent acrylic sheets, helping you buy high-quality ones.   1. Recognize through light transmittance: Good acrylic sheets emit pure light when illuminated by a phone flashlight. They do not turn yellow or blue. High-quality sheets have higher light transmittance.   2. Consider the color of the edges: The edges of excellent transparent acrylic sheets should be transparent. If they turn yellow, hazy, or white, they are definitely substandard or made from recycled materials.   3. Identify through soft rubber edges: To prevent collisions, new and good materials are packaged with soft rubber edges. Therefore, this can be used to distinguish between recycled materials and new materials. However, poured boards themselves may have PVC edges. Pay attention to the interface between PVC and acrylic. If it is obviously too yellow or white, it is also recycled decomposed material.   4. Feel the surface: If the surface of the acrylic sheet is smooth, round, delicate, and feels good, it is less likely to leave fingerprints. This indicates good quality.   5. Inspect the appearance: Good acrylic sheets have a beautiful appearance, good light transmittance, and no blemishes or few crystal points. They also do not have any adverse phenomena like yellowing or shrinking. On the contrary, poor quality materials are produced from recycled materials, and their appearance is poor with many blemishes, crystal points, and impurities. The quality cannot be guaranteed.   6. Identify through sound: If the surface of the acrylic sheet produces an unclear and dull sound when tapped, it is genuine. On the other hand, if the tapping sound is clear, it should be a PS board rather than an acrylic sheet. Also, pay attention to the fact that there are many claims of domestically produced acrylic sheets in the market, which are relatively cheap. They are most likely PS boards pretending to be acrylic sheets.   7. Check by burning: If there is a blue flame when burning, it confirms that it is acrylic, an acrylic sheet. If it produces black smoke, then it is a PS board or substandard material. After burning, press the burned area with a hard object and then move away. If there is drawing, it is extruded acrylic sheet. If there is no drawing at all, it is a poured board, which is the best way to differentiate.   The above are good methods for purchasing high-quality transparent acrylic sheets. When choosing transparent acrylic sheets, you can distinguish their quality through the above methods.   If you want to learn more about acrylic-related information, you can consult Chongqing Niu Bai Acrylic!

Acrylic plate casting plate: High molecular weight, excellent stiffness, strength and excellent chemical resistance. This sheet is characterized by small batch processing, which has incomparable spiritual activity in color system and surface texture effect, and has complete product specifications and is suitable for various special purposes. Acrylic extruder plate: Compared with casting plate, the molecular weight of extruder plate is lower and the mechanical performance is slightly weaker. However, this feature is conducive to bending and thermal molding, and when dealing with larger plates, it is conducive to fast plastic vacuum molding. At the same time, the thickness tolerance of the extruded plate is smaller than that of the cast plate. Because extruder plate is automatic production in large quantities, color and specifications are inconvenient to adjust, the diversity of product specifications is limited to some extent. Acrylic characteristics 1. Excellent transparency, colorless transparent plexiglass plate, with light transmittance of more than 92%.   Excellent weather resistance is very adaptable to the natural environment. Even if it is illuminated in sunlight for a long time, the wind and rain will not change its performance. The anti-aging performance is good, and it can be used at ease outdoors.

Compared with metals, stone and wood, plastic products have the advantages of low cost and strong plasticity. They are widely used in the national economy. The plastic industry occupies an extremely important position in today's world. Over the years, the production of plastic products has developed at a high speed around the world. Statistics show that China's plastic products production in the world ranking has always been in the forefront, a variety of plastic products have been ranked first in the world, China has become the world's plastic products production country.   From the perspective of demand, there is still a big gap between China's per capita plastic consumption and the developed countries in the world. According to statistics, as an indicator of the development level of plastic industry in a country, plastic steel ratio is only 30: 70, which is less than the world average of 50: 50, and far less than the developed countries such as the United States. In the future, with the technological progress and consumption upgrading of China's modified plastic, China's plastic products need to be expected to maintain a growth rate of more than 10%. Plastic products are widely used, and the huge downstream industry provides a strong support for the development of China's plastic products industry. With the promulgation of the " Detailed Rules for Revitalizing the Petrochemical Industry Planning ", China's plastic products industry has ushered in new development opportunities.   According to the research report, the development trend of high growth in plastic machinery and plastic mold industry, as well as the role of the steady development of light industry such as household appliances, food, beverages, leather and toys, It is also a favorable endogenous environment for the development of the plastic industry. The steady development of automobile, medical plastics, real estate, especially affordable housing and other industries has increased the demand of plastic products manufacturers and become a favorable exogenous environment for the plastic industry. At the same time, the acceleration of exchange rate changes, the increase of deposit reserve ratio and interest rate, the rise of raw materials and labor costs, and the tension of power supply and demand are also troubling the plastic products industry and forming public negative factors for most industries and enterprises.   On the basis of continuous breakthroughs in cutting-edge technology in the plastic industry, we mainly focus on the core technologies of key commonalities at present, and strive to narrow the gap with high-tech production technologies in developed countries. The acceleration of technological progress will give plastic materials and plastic products more new functions to meet the needs of the national economy.   Digital intelligent technology is the common enabling technology of product innovation and manufacturing technology innovation, and profoundly reforms the production mode and industrial form of manufacturing industry, which is the core technology of the new industrial revolution.

Precision is an embodiment of advanced molding technology in the processing industry of plastic products, which is of great significance to the industry. Clean production and ecology, for the plastic processing industry energy saving and emission reduction to open a new step.

Why is plexiglass different from ordinary glass?   Plexiglass and ordinary glass seem to be a family, in fact they are two completely different. The " father " of ordinary glass is silicate, but the " parents " of plexiglass are acetone, methanol, Sulfuric acid and hydrogen cyanide. The real name of plexiglass is called polymethacrylate. The name is quite awkward because it is a synthetic polymer, so people call it plexiglass in general.   Plexiglass character is generally much more stubborn than ordinary glass. Although its density is half smaller than ordinary glass, it is not as easy to break as glass glass. Its transparency is very good, Crystal clear, and very good thermoplastic, heat it, you can arbitrarily shape it into a glass rod, glass tube or glass plate, Because it has a favorite appearance and character, it has a wide range of uses. Jet aircraft often encounter severe vibration, sudden temperature changes and pressure on airflow when flying at high speed in the cloud. This is a severe test for the window glass of the cockpit.
