In the past ten years, plastics have penetrated into all walks of life and entered thousands of households with their convenience, and brought huge environmental pollution. International and domestic environmental protection policies, copyrights, laws and regulations, and environmental protection bills have been promulgated one after another. It proves that the demand for biodegradable plastics is gradually entering normalization and industrialization, and the development of fully biodegradable plastics is entering a golden period of vigorous development.

Completely biodegradable plastics: Completely biodegradable plastics are mainly made from natural macromolecules (such as starch, cellulose, chitin) or agricultural and sideline products through microbial fermentation or synthesis of biodegradable macromolecules, such as thermoplastic starch plastics, aliphatics Polyester, polylactic acid, starch/polyvinyl alcohol, etc. are all such plastics.

The plastics industry is a big industry. In 2003, the national output of plastic products reached 16.5053 million tons, including 811,000 tons of agricultural films, 3.269 million tons of packaging films, 3.12 million tons of tableware, and about 11 million tons of plastic pellets. Around 192 billion yuan per year, the annual profit exceeds 38 billion yuan. With the continuous enhancement of my country's environmental protection awareness and the improvement of environmental protection laws, completely biodegradable plastics will gradually replace ordinary plastic products.

Do you know what an omnidirectional conductive sponge is?

The omnidirectional conductive sponge is a conductive metal plating process based on the sponge. The back of the conductive sponge uses a conductive cloth as the substrate to combine the conductive adhesive with the sponge material, thereby achieving an omnidirectional conductive effect. It uses electroplating on the surface of the sponge to ensure good electrical conductivity, and the outermost nickel layer also increases the corrosion resistance of the material.

Do you know the relationship between conductive cloth tape and conductive cloth?

Conductive cloth adhesive tape is also a kind of adhesive tape made of conductive cloth. Its characteristics are the addition of "glue" characteristics to the conductive cloth, and its important characteristics can be referred to the term "conductive cloth". The "glue" that is commonly desired in the industry is conductive glue, which has a "nickel" component, in order to provide a magnetic shielding effect. However, there are also ordinary acrylic or hot melt adhesives that do not require conductive adhesive, in order to make the conductive cloth have good adhesion.

Where are conductive sponges widely used?

Conductive sponge is a material that mainly uses flame retardant sponge as the base material during the production process; An electronic material made by wrapping a layer of conductive cloth on the surface of the sponge and using a special process.

Are plastic products safe? Can they be heated and used?

Plastic products can be seen everywhere in daily life, but like Ms. Wang, many citizens know very little about the basic knowledge of plastic products. The author interviewed 20 citizens in a number of supermarkets and residential communities and found that 80% of the citizens often use plastic products in their lives, but they do not know how to use plastic materials and how to be safe.

The U.S. plastics processing industry is in a good situation with more optimism

Troy Nix, executive director of MAPP, said that the plastics manufacturing industry has officially recovered from the recession and is moving steadily towards exceeding the pre-recession sales level.
