Nowadays, Chinese children carry a heavy schoolbag with a lot of textbooks on their shoulders. Therefore, many schools have provided plastic lockers in classrooms for putting children's books in order to reduce their burdens in recent years. However, how to choose a suitable plastic locker for children? What kind of material is less harmful to children? Many schools choose ABS plastic lockers despite of their concern for the plastic material.
It is understood that ABS plastic is terpolymer of three monomers such as acrylonitrile (A), butadiene (B) and styrene (S). Acrylonitrile (A) has chemical resistance; butadiene (B) has good elasticity and toughness; styrene (S) has thermoplasticity. Therefore, ABS plastics have the same properties as the above three monomers. ABS plastic can be formed by injection molding and extrusion molding. ABS plastics have been widely used in machinery, electrical, textile, automobile, aircraft and ship fields. Taking ABS dehumidifying dryer as an example, the use of molecular sieve dehumidification can effectively remove the moisture inside the hygroscopic plastic molecules, solving the problems of engineering plastics such as insufficient strength, air bubble cracking, dimensional error and poor gloss to a certain extent. Another example is the ABS sheet production line. The temperature control system of the roller can accurately control the temperature of the press roll to make the sheet uniform in thickness. ABS plastics are also used for medical carts and medical beds in the medical field.
Compared with other materials, plastic lockers made of ABS plastic have the following advantages. First, ABS plastic lockers don't easily rot or rust. This kind of plastic locker is not equipped with metal accessories, which makes the plastic locker waterproof and not mildewed. In the case of using clean water to wash the plastic locker, you do not have to worry about rot and rust. Second, ABS plastic lockers have strong impact resistance. ABS plastic lockers made by the injection molding process not only are wear and impact resistant, but also have a long service life. Furthermore, ABS plastic lockers are environmentally friendly. ABS is a resin-friendly plastic that is resistant to high temperatures and is insoluble in most alcohols and hydrocarbon solvents, which make ABS environmentally friendly, safe, non-toxic and tasteless. Third, ABS plastic lockers have rich colors. ABS plastic lockers can be designed with different patterns and colors based on a child's personal preference. The designed color is bright and will not fade. And the pattern is beautiful. The ABS plastic is a general-purpose thermoplastic engineering plastic, and it is a plastic variety with excellent comprehensive mechanical properties. The ABS plastic not only has good rigidity, hardness and processing fluidity, but also has good toughness. It can be formed by injection molding, extruding or thermal forming. It is believed that people will be increasingly committed to the development and promotion of ABS materials, innovating and developing many new ABS composite materials, thus making the application of this excellent kind of plastic even broader due to the continuous development of the market.
