Prevent From Scratching Plexiglass Acrylic

Print Plexiglass Acrylic plate plating after the general term, with plastic lens instead of glass material lens, with light weight, not easy to break, easy molding, coloring and other advantages, the momentum of development is rising day by day, in the lens production has become a kind of technology. Plastic plate can be generally made into: single mirror, double mirror, with plastic mirror, with paper mirror, half lens can be made according to different requirements. Such as mobile phone, TV screen are daily can see.

Acrylic is suitable for secondary processing, such as mechanical processing, thermoplastic molding, blow molding, blister, solvent bonding, thermal printing, screen printing, vacuum plating after success is what we call acrylic lenses.

Acrylic plate from methyl methacrylate monomer (MMA) polymerization, namely polymethyl methacrylate (PMMA) plate plexiglass, is a special process of plexiglass.

Acrylic has the advantages of light weight, low price and easy to shape.Its molding methods include casting, injection molding, machining, acrylic hot forming and so on. Injection molding, in particular, can be mass produced, the process is simple, low cost. Therefore, its application is increasingly extensive, at present it is widely used in instrument parts, car lights, optical lenses, transparent pipes and so on.

After ceramic, acrylic is the best new material for making sanitary ware.Compared with traditional ceramic materials, acrylic in addition to unparalleled brightness, there are the following advantages: good toughness, not easy to damage; Repair sex is strong, should dip in with soft foam point toothpaste to be able to clean provide wipe a new; Soft texture, no cold winter feeling; Colorful, can meet the different taste of the pursuit of personality. With yakeli make stage basin, bath crock, sit implement, not only design is elegant, wear well, and have environmental protection effect, its radiate line and the radiate rate of human body oneself skeleton differ very little. Yakeli sanitaryware appears in the United States earliest, already occupied the 70% above of whole international market at present. Because of the difficulty and high cost of producing acrylic products, there are many low-cost substitutes in the market. These substitutes are also known as "acrylic", in fact, is the ordinary organic board or composite board (also known as sandwich board). Ordinary organic plate with ordinary plexiglass cracking material and pigment cast, surface hardness is low, easy to fade, with fine sand polishing after poor polishing effect. The composite board has only a thin layer of acrylic on the surface, with ABS plastic in the middle, which is easy to be stripped by thermal expansion and cold contraction in use. Section of the board of true and false acrylic, can from the subtle color difference and polishing effect to identify (1) building applications: Windows, soundproof Windows, light shade, telephone booth, decorative color mirror etc.

2. The advertising application: light boxes, signs, signs, exhibition stand.

3. Traffic application: train, automotive mirror, lens, etc.

4. The medical applications: infant incubator, all kinds of surgery medical equipment and supplies: arts and crafts, cosmetic mirror, stents, aquatic animals, toys, glasses, etc.

5. Industrial application: instrument surface plate and the cover, etc.

6. Lighting applications: fluorescent lamp, droplight, street lamps LED reflector, acrylic mirror, etc.

Process Characteristics

1. Acrylic contains polar side methyl, with obvious hygroscopicity, water absorption rate is generally 0.3% to 0.4%, before molding must be acrylic sheet Must be dry, dry conditions are 80℃-85℃ dry 4-5h

2. Acrylic molding in the temperature range of effective and obvious non-newtonian fluid characteristics, melt viscosity with the increase of shear rate will significantly decrease, melt viscosity is also very sensitive to temperature changes.Therefore, for the molding process of polymethyl methacrylate, increasing the molding pressure and temperature can significantly reduce the melt viscosity and obtain better fluidity

3. The starting flow temperature of acrylic is about 160℃, and the starting decomposition temperature is higher than 270℃, with a wide range of processing temperature.

4. Acrylic melt viscosity is high, the cooling rate is fast, products are easy to produce internal stress, so the molding process control requirements are strict, products also need to be processed after molding.

5. Acrylic is an amorphous polymer, shrinkage and its range of change are small, generally about 0.5%-0.8%, is conducive to forming a higher dimensional accuracy of plastic parts.

6. Acrylic has excellent machinability and its sections can be easily machined to any size required.
