Basic properties of plastics
Plastic type is malleable
As the name suggests, a plastic type is actually a formable material. The so-called plasticity of molding means that a good plastic material can be softened by household heating, and the antistatic plastic softened molding is taken out of the mold and solidified into a solid after special cooling. Design quantity. This kind of plastic home also has certain problems, that is, it will soften and deform when exposed to temperature, and some plastics will even be deformed by hot water, so plastic items are generally not suitable for connection. Boiling hot water.
Plastic type is elastic
Some plastic materials, such as synthetic materials, may also have some elasticity. After being pushed by an external force, the curled molecule is straightened by the overall flexibility, but once the stress is relieved, it returns to the unique curled state that makes plastics, including polyethylene and polyvinyl chloride, elastic. Movie merchandise. But some plastic materials are definitely not elastic.
Plastic type has high energy
Although the plastic material is not as tough as metal, it has relatively more energy and resistance compared to glass, ceramics, wood and many other materials. Plastic types help to make sturdy equipment and bearings on equipment.
The plastic material has rust resistance
The plastic type will not rust in humid air like metal, nor will it rot in humid air or be attacked by microorganisms like wood, and the plastic type is resistant to acid and alkali corrosion. Therefore, plastic materials are often used as drinking water and liquefaction pipes in chemical plants, doors and windows of structures, etc.
Plastic is insulating
The molecular sequence of plastics is defined by atoms covalently linked together. Molecules can neither ionize nor transfer electrons within the structure, so the plastic material is insulating. Plastic material enables you to make wire connections
