Today's children, carrying a small schoolbag on their shoulders carry thick textbooks. Therefore, in order to reduce their burden, in recent years, many schools have allocated schoolbags in the classroom for children to place books. However, how to choose a Kinds of chests suitable for children's use? Which kind of material is less harmful to the children? Under all kinds of troubles and concerns, ABS plastic case becomes the best choice for many schools.
It is understood that ABS plastics are terpolymers of three monomers: acrylonitrile (A), butadiene (B), and styrene (S). Among them, acrylonitrile (A) is chemically resistant, butadiene (B) High elasticity and toughness. Styrene (S) is thermoplastic. Therefore, ABS plastic has the same properties as the above three monomers. It can use plastic injection molding machines, extruders and other plastic molding equipment for injection molding. Plastic, blow molding, calendering, laminating, foaming, thermoforming, soldering, coating, electroplating and machining. In addition, ABS plastics in mechanical, electrical, textile, automotive, aircraft, shipbuilding and other fields Have been widely used.
Taking ABS dehumidifying dryer as an example, it uses molecular sieve to dehumidify, which can effectively remove the moisture inside the hygroscopic plastic molecules, to a certain extent, solve the problems of insufficient strength of engineering plastics, bubble cracking, dimensional error, silver bar phenomenon, poor gloss and other problems. Such as ABS sheet production line, the roller temperature control system of the equipment, can accurately control the pressure roller wheel temperature, so that the thickness of the plate is uniform. In the medical field, ABS plastic is also used in medical carts, medical beds and other equipment.
Compared to other materials, the schoolbag cabinet made of ABS plastic has the following advantages:
First of all, it is not easy to rot and rust. The schoolbag cabinet of this kind of material is not equipped with other metal fittings. It is waterproof and moisture-proof without mildew, and when it is cleaned with clean water, it does not have to worry about rot and rust.
Secondly, it has a strong impact resistance. ABS plastic bag cabinet made of injection molding process, connected with helium, which not only wear and impact, but also has a strong life.
In addition, environmental protection is pollution-free. ABS is an environmentally-friendly plastic that is resistant to high temperatures, insoluble in most alcohols and hydrocarbon solvents, and is environmentally safe, non-toxic and tasteless.
Finally, the free collocation of the color pattern. This kind of material of the school chest, according to the child's personal preferences, a variety of colors and designs of the design. And the design of the color is not faded, beautiful and beautiful atmosphere.
ABS plastic is a general-purpose thermoplastic engineering plastic. It is a plastic variety with excellent mechanical properties. It not only has good rigidity, hardness and processing fluidity, but also has high toughness characteristics. It can be injected, extruded or thermoformed. With the continuous development of the market, people will increasingly commit to the development and promotion of ABS materials, and innovate and develop many new types of ABS composite materials, which will promote the wide application prospect of this excellent plastic variety.
