Rubber is a polymer—a compound containing large molecules that are formed by the bonding of many smaller, simpler units, repeated over and over again. The same bonding principle—polymerization—underlies the creation of a huge range of plastics by the chemical industry. The first plastic was de...
Varieties of antibacterial agent and their mechanism are introduced.Development situations of antibacterial plastics as well as test methods for their performance at home and abroad are described.Taking PVC antibacterial plastics as examples,the applications of several antibacterial agents are illustrated.关键...
At the global level, the issue of marine (micro)plastics has been recognized in the UN SDGs under Goal 14 which is to: Conserve and sustainably use the oceans, seas and marine resources for sustainable development. Specifically, in target 14.1: By 2025, prevent and significantly reduce marine...
Although with the development of the society, people are more and more interested in the environment, according to the Plastics Waste Index, "Single-use plastics are some of the hardest items(物品) to recycle and end up creating global waste mountains." However, there are simple things restaura...
of the thermosets—plastics that can be cast and moulded while hot, but cannot be softened by heat and reshaped once they have set. Bakelite was a good insulator, and was resistant to water, acids and moderate heat. With these properties it was soon being used in the manufacture of ...
It was put forward that plastics additives with high efficiency, environment friendly, special performance and application and self-determination intellectual asset should be developed at home. The three wastes problems, comprehensive use of materials, cost reduction, high additional value should be ...
In this paper, several methods of solving pollution of waste plastics were introduced, and the status quo of waste plastics recovery and utilization was analyzed in China.A small-scale experiment was finished to recover fueloil from polyolefine plastics by using own-made catalytic pyrolysis with go...
This paper explores the historical development of conventional plastics, tracing their evolution from early forms to their pervasive use in modern society. Its observations include the rise of mass plastic production during World War II and the post-war development, showcasing plastics' economic and ...
Improving access to antibiotics will save lives and reduce the rise and spread of drug-resistant infections. Instead of traditional ‘last mile’ global health solutions, global leaders need to support efforts to develop suitable antibiotics and their rational use, ensuring that countries have the cap...
