[Edit this paragraph] Introduction of Acrylic
Acrylic acid is a general term for acrylic acid and methacrylic acid chemicals, which is transliterated from English Acrylics. Comprises monomers, plates, granular materials, resins and composite materials, wherein the acrylic plate is formed by polymerizing polymethyl methacrylate monomer (MMA), namely polymethyl methacrylate (PMMA) plate plexiglass, and the plexiglass comes from the brand name "Oroglas" (a PMMA plate) and is taken from "plexiglass" (namely plexiglass). But in recent years, all transparent plastics such as PS and PC are collectively called plexiglass.
Acrylic acid-physical properties
Density: 1. 19kg/dm3 transmittance: 99% impact strength ≥ 16kg/cm3 tensile strength ≥6 1Kg/m3 thermal deformation temperature ≥78℃ thermal softening temperature ≥ 105℃ What kind of adhesive is used for acrylic? The bonding method of acrylic should be tailored according to different needs. 502 can be lower, but chloroform with high requirements is not necessarily the best, and acetone is also needed, but it is best to have several mixed formulas.
[Edit this paragraph] acrylic production process
Acrylic board can be divided into casting type and extrusion type according to production technology. The performance of cast plate is better than that of extruded plate, and the price is also more expensive. Casting plate is mainly used for carving, decoration and handicraft production, while extrusion plate is usually used for making advertising signs and light boxes.

[Edit this paragraph] Acrylic board and plexiglass
"Plexiglass" comes from British Plexiglass. In recent years, in some areas, all plates made of transparent plastics are collectively called plexiglass. Actually, this is not right. Acrylic refers to pure polymethyl methacrylate (PMMA) material, and PMMA plate is called acrylic plate.
Characteristics and advantages of acrylic board
Acrylic has high transparency, with a light transmittance of 92%, and has the reputation of "plastic crystal". And has excellent weather resistance, acid resistance and alkali resistance. It is especially suitable for outdoor use, ranking first among other plastics, with good surface hardness and luster, great processing plasticity and long thermoforming time, and can be made into various required shapes and products. In addition, there are many kinds of colorful plates (including translucent colored plates), and another feature is that thick plates can still maintain high transparency.
[Edit this paragraph] The history of acrylic
Acrylic, the common name of specially treated plexiglass. The research and development of acrylic has a history of 100 years. 1872 discovered the polymerization of acrylic acid; The polymerization of methacrylic acid in 1880 is known; The synthesis method of 190 1 year propylene polyacrylate was completed. In 1927, the industrial production was attempted by using the aforementioned synthesis method; 1937, the industrialized manufacture of methyl methacrylate was successful, and large-scale manufacturing was realized. During World War II, acrylic acid was first applied to the windshield of aircraft and the mirror of tank cab because of its excellent toughness and light transmittance. 1948 the birth of the world's first acrylic bathtub marks a new milestone in the application of acrylic.
[Edit this paragraph] The use of acrylic acid
PMMA has the advantages of light weight, low price and easy molding. Its forming methods include casting, injection molding, machining, thermoforming and so on. Especially injection molding, which can be produced in large quantities, has simple process and low cost. Therefore, its application is increasingly extensive. At present, it is widely used in instrument parts, automobile lights, optical lenses, transparent pipes and so on.
Acrylic is the best new material for making 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 be damaged; Strong recovery, as long as you dip in soft foam toothpaste, you can wipe the sanitary ware; Soft texture, no icy feeling in winter; Bright colors can satisfy the individual pursuit of different tastes. The basin, bathtub and toilet made of acrylic are not only exquisite and durable, but also environmentally friendly, and their radiation level is almost the same as that of human bones. Acrylic bathroom first appeared in the United States, and now it has occupied more than 70% of the entire international market.
Due to the difficulty and high cost of acrylic production, there are many low-quality and low-cost substitutes on the market. These substitutes, also called "acrylic", are actually ordinary organic boards or composite boards (also called sandwich boards). Ordinary plexiglass plate is cast with ordinary plexiglass cracking material and pigment, which has low surface hardness and is easy to fade, and the polishing effect is poor after polishing with fine sand. The composite board has only a thin layer of acrylic with ABS plastic in the middle, which is easy to be layered due to thermal expansion and cold contraction in use. True and false acrylic can be identified from the subtle color difference and polishing effect of the plate section.
1. Building applications: windows, soundproof doors and windows, lighting covers, telephone booths, etc.
2. Advertising applications: light boxes, signboards, signboards, booths, etc.
3. Traffic applications: doors and windows of vehicles such as trains and automobiles.
4. Medical applications: baby incubators, various surgical medical instruments, civil articles: bathroom facilities, handicrafts, cosmetics, brackets, aquariums, etc.

[Edit this paragraph] The characteristics of acrylic board and its application in the market
Acrylic board can be divided into casting board and extrusion board according to production technology.
Acrylic casting plate
High molecular weight, excellent rigidity, strength and excellent chemical resistance. This kind of plate is characterized by small batch processing, unparalleled flexibility in color system and surface texture effect, complete product specifications and suitable for various special purposes.
Acrylic extrusion plate
Compared with cast sheet, extruded sheet has lower molecular weight and slightly weaker mechanical properties. However, this feature is beneficial to bending and thermoforming, and is beneficial to rapid plastic vacuum suction molding when dealing with large-size plates. At the same time, the thickness tolerance of extruded plate is less than that of cast plate. Because the extruded board is produced automatically in large quantities, the color and specifications are not convenient to adjust, so the diversity of product specifications is limited to some extent.
Over the years, thermoforming has been one of the most creative uses of acrylic board. With the improvement of processing technology, the variety and performance of products are enriched and improved, compared with other traditional advertising signboard materials, acrylic is simpler and safer to process, and the cost performance of products is more reasonable.
Characteristics and advantages of acrylic board
Unparalleled outdoor weather resistance
The transparent plate is crystal clear.
High gloss, smooth and flat surface.
Product range is complete, with transparent, translucent, milky white and other colors and various surface effects.
Excellent processing performance; It is simple and convenient to make signboards and signs with outstanding visual effects by thermoforming, and the cost is reasonable.
Green and environment-friendly, the waste can be completely recycled, and the recycling is simple and easy.
Excellent surface hardness and scratch resistance.
Good chemical resistance, superior to most other plastic materials.
Easy to clean and maintain, ensure that signs and light boxes are as new as ever.
Difference and simple identification method of superior and inferior acrylic sheets
Acrylic board also has advantages and disadvantages. At present, there is a cheap and low-quality acrylic board in the domestic acrylic board market-recycled acrylic board. This kind of plate is made of recycled acrylic scraps, regenerated MMA (methyl methacrylate) monomer is obtained by thermal degradation, and then it is obtained by chemical polymerization. It should be pointed out that in foreign countries, acrylic production enterprises have formulated scientific waste recycling plans and invested huge sums of money to build waste cracking plants. After strict technological process, pure MMA monomer can be obtained again, which is no different from the newly synthesized monomer in quality. At present, some small workshops with backward technology in China, due to one-sided pursuit of profits, poor production conditions and low purity of degraded monomers, often dare not compliment the quality of the plates.
Brand new transparent acrylic board
Excellent ultraviolet resistance, outdoor 10 years will not turn yellow, will not fade, will not shed light, will not crack.
The light transmittance is greater than 92%, and the section is transparent and colorless.
High surface hardness, comparable to aluminum and brass.
Excellent crack resistance and chemical resistance.
High-quality protective film provides full protection.
Regression transparent acrylic board
Anti-ultraviolet performance is very poor, it will turn yellow in half a year at most, and cracks are easy to appear in the sun.
The light transmittance is less than 86%, and the section is yellow.
Low surface hardness, easy to scratch.
Easy to crack
The quality of protective film is poor and it is easy to age and deteriorate.
Through this simple identification method, it is easy to identify the quality of acrylic board and avoid some unnecessary losses.
Due to people's ignorance and low price of recycled acrylic board, recycled acrylic board still occupies a large market space in China. However, it can be predicted that with the deepening of people's understanding of acrylic materials, the living space of recycled plates will become smaller and smaller.
[Edit this paragraph] Long-term performance
Like all plastic materials, the impact resistance of acrylic products will weaken with the decrease of temperature. High-quality acrylic board usually adopts high-quality raw materials and unique formula production technology, which makes it have excellent long-term outdoor performance. In the application field of light boxes and signboards, the expected outdoor service life can exceed 10 years.
Acrylic product performance
Weather capacity
Acrylic board has excellent outdoor weather resistance and can be regarded as the best among all plastic materials. Under normal outdoor use conditions, the mechanical strength and appearance of acrylic signboards after reasonable design and processing will not decrease after 10 years of use.
Light transmission performance of color plate
High-quality acrylic plates will be produced according to strict quality standards to ensure the same color in different batches and plates. Because the color of the color plate is evenly distributed along the thickness direction of the whole plate, the wear marks on the surface of the anti-card will have a certain impact on the appearance color when illuminated.
The transmittance of most acrylic color plates will decrease with the increase of plate thickness, which may adversely affect the application of some logos-for example, when the same logo uses color plates with different thicknesses at the same time, there will be obvious color difference. In this case, we can consider using some acrylic color plates with fixed transmittance. Although the plates have the same thickness, they show the same color transmittance.
[Edit this paragraph] Acrylic boards and advertising signs
Whether it is a multinational company or a small shop, factory or office that wants to establish a unified logo around the world, it needs a durable, eye-catching, unique and economical logo. The excellent comprehensive performance of acrylic board can fully meet the above requirements, and the acrylic light box is uniform, soft and bright, eye-catching and energy-saving; Acrylic light box signs are particularly eye-catching and easy to process when there is no light during the day. By choosing suitable varieties and processing methods, various light boxes or signs can be made. Acrylic light box is durable, can be used outdoors for more than ten years, and it is also very convenient to install and maintain. If the signs of acrylic light boxes need to be cleaned regularly, the method is simple. Scrubbing can be done with soapy water and soft cloth or brush, but hard brush or coarse cloth is not allowed. If it is necessary to improve the antistatic degree of light box, it is effective to spray special antistatic agent.
You may have noticed that McDonald's restaurants all over the world use acrylic logo with uniform color and shape; BP chose the unique green and yellow acrylic logo to decorate gas stations around the world. Marks Japan, a famous department store chain, installed eye-catching and bright signs in more than 400 stores in Europe and Asia by using acrylic boards with different light transmittance.

[Edit this paragraph] The characteristics of plexiglass acrylic
[ 1]
high grade of transparency
Plexiglass is the best polymer transparent material at present, and its light transmittance is as high as 92%, which is higher than that of glass. The lamp tube of solar lamp called artificial small sun is made in time, because it can completely transmit ultraviolet rays in time. Ordinary glass can only transmit 0.6% ultraviolet rays, while plexiglass can transmit 73%.
High mechanical strength
The relative molecular weight of plexiglass is about 2 million, and it is a long-chain polymer compound with a soft molecular chain. Therefore, the strength of plexiglass is relatively high, and its tensile and impact resistance are 7 ~ 18 times higher than that of ordinary glass. One kind of plexiglass is heated and stretched, and the molecular segments are arranged in a very orderly way, which greatly improves the toughness of the material. Nail into this plexiglass, even if the nail penetrates, there will be no cracks on the plexiglass. This plexiglass won't break into pieces after being punctured by bullets. Therefore, the stretched plexiglass can be used as bulletproof glass and also as the cockpit cover of military aircraft.
light weight
The density of plexiglass is1.18-1.19 kg/dm3. The weight of the same size material is only half that of ordinary glass, and that of metallic aluminum (belonging to light metal) is 43%.
Easy to process
Plexiglass can not only be cut by lathe and drilled by drilling machine, but also be bonded into various shapes of appliances and plexiglass products by acetone and chloroform. It can also be processed into various products such as aircraft cockpit covers, dentures and braces by plastic molding methods such as blow molding, injection molding and extrusion.
[Edit this paragraph] Matters needing attention in making acrylic handicrafts
1, the thermal deformation temperature of ordinary acrylic board is about 100 degrees, and the continuous use temperature should not be higher than 90 degrees.
2. The surface hardness of acrylic board is equivalent to that of aluminum, so attention should be paid to avoid scratching the surface when using or processing. If it is scratched, the original bright surface can be restored by polishing.
3. Acrylic board is easy to generate static electricity and absorb dust. When cleaning, use a soft cotton cloth dipped in 1% soapy water to wipe it.
4. The cast acrylic plate has a certain expansion coefficient, so there should be enough expansion gap when installing the acrylic plate.
How to avoid deformation of acrylic products
1, the mounting frame must be reserved with contraction and expansion gaps.
2. Oval screw holes must be drilled and locked with screws.
3. Choose elastic rubber washer
4. Hot forming can improve impact strength and release internal stress.
6. Hot pressing into waves, diamonds and semicircles can prevent the acrylic board from being deformed due to its own weight.
6. When using large-format acrylic board, the thickness must be increased to prevent the board from sagging and deformation due to its own weight.
7, choose the appropriate thickness, avoid bending deformation of acrylic board caused by wind load.
[Edit this paragraph] The plexiglass market has a broad development prospect.
[2] Plexiglass is an important thermoplastic with early development, which has transparency, stability and weatherability, easy dyeing, easy processing and beautiful appearance, and is widely used in the construction industry.
In architecture, plexiglass is mainly used for lighting bodies, roofs, shed roofs, stairs and indoor wallboard. In recent years, the application of plexiglass in lighting lampshades and car lights of expressways and high-grade roads is also quite rapid. With the construction of hotels, guesthouses and high-grade houses in big cities, daylighting bodies have developed rapidly. The plexiglass extruded board lighting body has the characteristics of high overall structural strength, light weight, high light transmittance and good safety performance, and has great advantages compared with inorganic glass lighting devices.
In sanitary ware, plexiglass can be used to make bathtubs, washbasins, dressing tables and other products. Plexiglass bathtub has been widely used in recent years because of its luxurious appearance, deep texture, easy cleaning, high strength, light weight and comfortable use.
At present, the United States and Japan have made it compulsory to use plexiglass in primary and secondary schools and kindergartens. With the continuous improvement of China's laws, it is expected that corresponding regulations will be made in the near future. At the same time, all parts of our country have accelerated the pace of urban construction, and a large number of road signs, advertising light boxes and telephone booths made of plexiglass will also appear, so plexiglass has great development space and broad market prospects.
[Edit this paragraph] Acrylic, a plastic comparable to diamond.
[3] Acrylic is not only a good industrial material, but also known as plastic crystal. It is clear, transparent, bright and malleable, and it is increasingly used in fashion and fine products.
Most of the popular acrylic products are made of acrylic particles through injection molding and high-quality accessories.
