Among the five general engineering plastics, PC (polycarbonate) is the only product with good transparency. Taking advantage of this advantage, PCs are successfully used in many fields, including electronic appliances, medical supplies, building energy conservation, auto parts and many other rapidly developing industries.
Polycarbonate production process is relatively complex, only a few large companies in the world have production capacity, domestic manufacturers are all foreign or joint venture companies, with the increase in demand in the construction and automotive industries in North America and Western Europe, especially in Asia It is China that is increasing the scale of investment in PC production.
1. Analysis of the advantages and disadvantages of PC application prospects
At present, there are two main production processes of PC: transesterification and phosgene. The former makes it difficult to achieve high molecular weights due to the need to distill off high-boiling phenols. The latter uses phosgene, a highly toxic raw material in the reaction process, which puts forward extremely high requirements for technology and safety. If phenol itself is also toxic, the entry threshold for PC production makes it a certain monopoly sex.
01. Advantages
PC is an engineering plastic with excellent comprehensive properties. It has high strength, ductility and toughness, and has excellent impact strength. At the same time, it has excellent electrical properties, good light transmittance, and light transmittance can exceed 90%.
In addition, the research on its flame retardancy is quite mature, and many alloy materials choose PC as one of the modifiers. The thermal insulation performance of PC used as a board is 1.25 times that of ordinary glass, the impact strength is 250 times that of glass, and the density is only half that of glass, so it has great application potential in the construction industry.
In addition, PC is easy to mold and process, and can replace some current auto parts to achieve the purpose of weight reduction and energy saving, especially in my country's auto industry, the use of PC only accounts for 5% of the total consumption, compared with 20% in foreign countries. Great room for development.
In the electrical and electronic industry, PC's high impact resistance, high heat distortion temperature, insulation, fire resistance and dimensional stability of the comprehensive excellent performance, so that its usage has always maintained a strong growth.
Given that billions of PCs are imported every year to meet demand, the market outlook is very optimistic.
02. Disadvantages
Although the PC has a wide range of uses, but there are many competitors, the cost is still high, and it can be replaced in many application fields.
For example, low-cost acrylonitrile resin (SAN) can be used for refrigerator fresh-keeping compartments and protective layers that do not require high temperature and impact strength.
In terms of single-use containers, transparent PP, PET, PVC are more competitive.
In the food utensils sector, PC products that could be used as water bottles and baby bottles are restricted in some countries (eg EU, Canada, USA) because they are considered to contain BPA.
PC products are being forced to move towards better, better and higher-end fields, which puts forward higher and broader requirements for their new product development capabilities and application field exploration.
Second, the main application areas of PC
01. Electronic appliances
PC has good insulation and strength in a wide range of temperature and humidity, and is widely used as shells, covers and structural parts of computers and various commercial appliances.
It can be used to make insulating sleeves, coil frames, power tool housings, refrigerator freezer drawers, vacuum cleaner parts, etc. It can also be used to manufacture parts with high dimensional accuracy, such as computers, video recorders, TV sets, and communication equipment such as switches and relays. Because of its excellent optical transparency, light scattering and dimensional stability, it is used in large-screen LCD diffusers above 42 inches.
PC/ABS alloy not only reduces cost, but also has better processability and UV resistance, and can be used to produce thin-walled parts for injection-molded notebook computers and laptop computers.
02. Building materials
For a long time, glass has been the main lighting material in modern life, but for the roof of large-area buildings, it requires "light weight and high strength". The high strength and low density of PC itself make up for the heavy and fragile characteristics of glass, combined with its high safety. , easy installation, strong designability and other advantages, thus occupying a place in the field of contemporary architecture.
Of course, just relying on the properties of the material itself is not enough to complete a grand building. Just as cement still needs steel reinforcement, PC has added a lot of design as a building material.
With the improvement of PC board production technology and production technology, PC hollow board as a new material has injected many new architectural elements into building roofs, facades and curtain walls.
