Polyvinyl chloride (PVC) Polyvinyl chloride is a low-cost, widely used plastic. It has the characteristics of waterproof, moisture-proof and corrosion resistance, so it is often used in the manufacture of pipes, cables, wallpaper, doors and Windows. However, due to its impact on the environment, some applications are gradually being replaced by other environmentally friendly materials. Polystyrene (PS) Polystyrene is commonly used to make packagingMaterials such as plastic bags and foam.
Polyethylene (PE) Changzhou wireless coil : Polyethylene is a commonly used plastic material, with good flexibility, impact performance and film formation. It is widely used in packaging film, agricultural film, plastic modification and other fields. Polypropylene (PP) : Polypropylene is a plastic material with many uses, which can be used in drawing, fiber, injection, BOPP film and other fields.
Plastic wrap: This plastic packaging material is mainly made of ethylene, sometimes with the addition of other chemicals. Keep freshMembranes can be divided into types such as polyethylene, polyvinyl chloride and polyvinylidene chloride, which are used in food packaging to keep food fresh. Plastic film: Plastic film is made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins for a variety of packaging and covering purposes.
Polyester (PET) : Polyester is a transparent or translucent plastic material with good strength and toughness. Commonly used in the manufacture of beverage bottles, food packaging, etc. In addition, it is also used to make fiber products, such as clothing and curtains. These plastic materials are widely used in daily life and industrial production, and they have different characteristicsThe characteristics and uses can meet a variety of different needs.
1, direct current means that the direction of the current is always unchanged. Direct current is an important type of current that is different from alternating current as we know it. The following is a detailed explanation of direct current: Definition of direct current Abbreviation for direct current, meaning that the current always flows in the same direction. There is no periodic change in the direction of the current in this current path.
2, the meaning of direct current Direct current is a single chargeForward flow, also known as constant current. It is different from alternating current, which changes direction periodically. Interpretation of direct current definition: Direct current refers to the current that always flows in a fixed direction in a circuit. It does not change periodically like alternating current, and the strength and direction of the current remain constant. Power supply and circuit: DC power supply is mainly battery.
3, direct current (DC) is a unidirectional flow or movement of electric charges, usually electrons. The current density varies over time, but generally the direction of movement is the same at all times. The direction of direct current does not change with time. It is usually divided into pulse direct current and steady current. Pulsating direct current has an alternating current component.
4. Direct current is generated by electrochemical and photoelectric units and batteries. In contrast, in most countries, the current flowing out of the device is alternating current (AC). Alternating current can be converted to direct current by means of a power supply consisting of a converter, a rectifier (which prevents the current from flowing in the opposite direction), and a filter (which eliminates the jitter in the current flowing out of the rectifier). Virtually all electronic and computer hardware requires direct current to work.
