What is Plastic? Difference Between Plastic and Plastic

Plastics are synthetic polymer compounds, also known as polymers or macromolecules, and are also commonly known as plastics or resins, which can freely change the shape and style. It is a material made by polymerization of monomer raw materials by synthesis or condensation reaction, and is composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, pigments, etc., and its main component is synthetic resin. The term resin was originally named after lipids secreted by animals and plants, such as rosin, shellac, etc., and currently resin refers to polymers that have not been mixed with various additives.

Resin accounts for about 40 100 of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins with little or no additives, such as plexiglass, polystyrene, etc.

The so-called plastic is actually a kind of synthetic resin, and its shape is similar to that of pine resin in natural resins, but it is called plastic because it is synthesized by chemical force.

Mainly composed of carbon, oxygen, hydrogen and nitrogen and other organic or inorganic elements, the finished product is solid, in the manufacturing process is a molten liquid, so it can be melted by heating, pressurized to make it flow, cooled to solidify, and form a variety of shapes, can withstand a certain external force, has good mechanical properties and high and low temperature resistance, good dimensional stability, can be used as engineering structure of plastics This large and changeable material group is called plastic. Plastic:

It refers to a plastic (flexible) material with high molecular weight synthetic resin as the main component, adding appropriate additives, such as plasticizers, stabilizers, flame retardants, lubricants, colorants, etc., or rigid materials formed by curing and cross-linking.

The girl accidentally turned into a plastic person, and she could change her shape at will with her hands, so she began to have manual plastic surgery.

Plastic is generally the abbreviation of plastic rubber, which is a kind of colloidal solid with a variety of shapes of finished products. The raw materials for plastic production are mainly carbon-containing compounds, including but not limited to carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements.

Due to its strong plasticity, plastic can replace the metal parts in some industrial products to a certain extent, and plastic is gradually becoming one of the main materials in industrial parts.

Plastic can be melted by heating, increasing pressure can make the melted liquid plastic material flow, the flowing plastic material can be cooled after being loaded into the mold to form a solid, and the specific shape of the plastic product can be made according to the production needs.

Plastic refers to a plastic (flexible) material with high molecular weight synthetic resin as the main component, adding appropriate additives, such as plasticizers, stabilizers, antioxidants, flame retardants, colorants, etc., or rigid materials formed by curing and cross-linking.

General plastics refer to this kind of products with wide use, rich material sources, low cost, the largest amount of application, and easy molding, which can be made into plastic products of various shapes. General plastics include polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS and acrylonitrile styrene copolymers, phenolic resins (PF), amino resins (UF), etc.

The so-called plastic is a polymer compound with a molecular weight of more than 10,000. That's the synthetic resin we've only harvested. But synthetic fibers rubber. There are also some crosslinkers, which are not included in it.

1. Introduction of plastics: 1) The main ingredient of plastic raw materials is resin, which is infiltrated into various auxiliary materials or additives by polymer synthetic resin as the main ingredient, which has plasticity and movement at a specific temperature and pressure, and can be molded into a certain shape, and keep the shape unchanged under certain conditions; 2) Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, and sound attenuation performance.

3) Most of the plastic raw materials are extracted from some oils, and the most familiar part of the PC material (polycarbonate plastic) is extracted from petroleum, and the PC material has a gasoline smell when burned; ABS (acrylonitrile butadiene styrene copolymer plastic) is extracted from coal, and ABS will be soot-like when burned and extinguished; POM (polyoxymethylene plastic) is extracted from natural gas, and POM will have a very smelly gas smell when it is burned. 2. Introduction of plastics: 1) Plastic raw materials are heated and compressed, and the linear expansion coefficient is much larger than that of metal; 2) The stiffness of general plastic raw materials is an order of magnitude lower than that of metal; 3) The mechanical properties of plastic raw materials will decrease significantly under long-term heating; 4) Generally, plastic raw materials are temporarily stressed at room temperature and under stress lower than their yield strength, and permanent deformation will occur 5) Plastic raw materials wholesale is very sensitive to notch damage; 6) The mechanical properties of plastic raw materials are usually much lower than those of metal, but the specific strength and specific modulus of some composite materials are higher than that of metal, and if the product design is reasonable, it will be more able to play a superiority; 7) Generally, the mechanical properties of enhanced plastic raw materials are heterogeneous; 8) Some plastic raw materials will absorb moisture and cause changes in size and performance; 9) Some plastics are flammable.

3. The difference between the two Plastic does not belong to plastic, but its main component is resin, and the main component of plastic is also resin, and the two are just the same main component, not the same thing.

Plastic refers to the plastic billey (flexible) material with high molecular weight synthetic resin as the main component, adding appropriate additives, such as plasticizers, stabilizers, flame retardants, lubricants, colorants, etc., which are processed and molded, and are widely used in household appliances, automobiles, mobile phones and other electrical appliances.

Plastics: 1. The main components of plastic raw materials are carbon-containing compounds.

2. Plastic raw materials: It is a material that is made of polymer synthetic resin (polymer) as the main ingredient, infiltrated with various auxiliary materials or additives, and has plasticity and fluidity under specific temperature and pressure, and can be molded into a certain shape and keep the shape unchanged under certain conditions.

3., polymer: refers to the pure material banquet or polymerization material produced by the polymerization process. Both natural resin and synthetic resin are polymer polymers, referred to as polymers.

4. Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, and sound attenuation.

Most of the plastic raw materials are extracted from some oils, and the most familiar part of the PC material is extracted from petroleum, and the PC material has a gasoline smell when burned; ABS is extracted from coal, and ABS will be soot-like when burned and extinguished; POM is extracted from natural gas, and POM will have a very foul gas smell when it is burned.
