What do you need to know about acrylic sheets?

1. Acrylic and plexiglass: These two refer to the same material. The former is transliterated from English (acrylic), and the latter is the chemical abbreviation of pmma, which is the raw material for producing acrylic sheets. As for some people saying that plexiglass is made in China and acrylic is imported, it is naturally wrong. the

2. The most widely used acrylic is transparent board, which has high light transmittance, easy processing, inkjet printing and color printing. It can be used instead of ordinary glass in some places. the

3. Specifications: 1220*2440mm is the most conventional size at present. Generally, factories will prepare multiple sets of production molds or directly adjust equipment to achieve the purpose of size customization. Due to the different production processes, the cast plate has a relatively large limit on the size, while the extruded plate has more space to play in the length. the

4. Tolerance: There will be tolerances in the production of any product, which cannot be avoided. Acrylic is no exception, rarely being thick enough. Generally, the tolerance is maintained at about ±0.2. Among them, the cast plate has a special process, and the tolerance will increase with the increase of the thickness; the extruded plate is easy to control due to the mature process, and the control of the tolerance is better, which is more suitable for mass production. . the

5. Regarding the return material: the utilization rate of acrylic will not reach 100%, and some leftover materials will be left after cutting and processing. These leftover materials may be recycled and reenter the factory to be decomposed and processed into acrylic boards, which are called joint venture boards. Or return board. The quality of this kind of board is very different from that of the new material board, for example, it cannot be bent or polished.

6. Temperature: Acrylic is a kind of plastic product, so the temperature has a great influence on it. For example, if the local temperature is too high during cutting, the plate will melt and stick to the knife. Use the highest temperature can not be higher than 90 degrees. It will soften when it reaches about 113°C, and acrylic will decompose when the temperature is slightly higher than 270°C. the

7. Types: For example, it can be divided into casting board and extruded board according to processing technology; it can be divided into brand new material board and joint venture board according to raw material; it can be divided into transparent board and color board according to color; it can be divided into sanitary board according to use, Flame retardant panels, sound insulation panels, diffusion panels, light guide panels, etc. the

8. Plate processing: Generally, the processes that can be used for acrylic include engraving, cutting, bonding, polishing, silk screen printing, bending, trimming, sandblasting, heat transfer printing, blistering, etc.
