英语作文关于化学知识
英语作文关于化学知识Chemistry is a scientific discipline that studies the composition, structure, properties, and reactions of matter. It is a fundamental science that underpins many other fields, from biology to materials science. Here's a brief exploration into the realm of chemistry.The Building Blocks of Chemistry: Atoms and MoleculesAt the heart of chemistry lies the atom, the smallest unit of an element that retains all the properties of that element. Atoms combine in specific ways to form molecules, which are the foundation of all substances. The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.Chemical Reactions: The Dance of AtomsChemical reactions occur when atoms rearrange to form new substances. These reactions can be classified into various types, such as synthesis, decomposition, single displacement, double displacement, and redox reactions. Each type has its own set of rules and characteristics that govern how atoms interact.The Role of Energy in Chemical ReactionsEnergy plays a crucial role in chemical reactions. Reactionscan be exothermic, releasing energy, or endothermic, absorbing energy. The study of energy changes in reactions is known as thermodynamics, which helps us understand whycertain reactions occur spontaneously and others do not.Chemical Equilibrium: Balancing ReactionsNot all reactions go to completion. In some cases, a state of equilibrium is reached where the rate of the forward reaction equals the rate of the reverse reaction. This concept isvital in understanding how reactions can be controlled and manipulated in industrial processes.Chemistry in Our Daily LivesChemistry is not just confined to laboratories. It is all around us, from the food we eat, the air we breathe, to the materials we use. For example, the chemistry of cooking involves complex reactions that transform ingredients into delicious dishes. Similarly, the chemistry of plastics and polymers has revolutionized the way we manufacture and use everyday items.The Future of ChemistryChemistry continues to evolve, with new discoveries and technologies emerging every day.

Degradable Plastic Bags
The plastic material, is a high molecular weight organic matter as main component. Over the past few years plastics inspire countless innovations that help make life better, healthier and safer every day. For example, plastic bags help keep the foods we eat and serve our families safer and fresher than ever before. But it cause the white pollution. So June 1, 2008 started the implementation of the "plastic limit order" .To protect our environment, we should use more environmental plastic bags. The production of plastic bags added in the process of degradation masterbatch plastic bags that degradable plastic bags, degradable plastic bags for 90 days can automatically decompose in accord with certain conditions. To the plastic film bag as raw material for the production of plastic bags, we used plastic bags: the bag bag, shopping bags, handbags, handbags, bags, vest belt and industrial.
Some domestic "manufacturers of degradable plastic" method is mainly used in PVC, by adding a certain proportion of starch biodegradable agents, thus changing the hydrocarbon structure of PVC, by microorganisms and decomposition. Another approach is the incorporation of photosensitizer, in plastics, in the sunshine
under the plastic gradually decomposition. Or the "light" and "biological" combined with characteristics of degradation, photodegradation and biodegradation plastic. But the essence of the two methods is changed the structure of PVC molecular chain, simply, is through the biological degradation agent or photosensitizer, the molecular links between interrupted, not easy to larger molecules into small molecules is relatively easy decomposition, but the essence of PVC has not degradation did not change.
Our members are proud to manufacture materials that can help us to do more with less and contribute to a more efficient use of resources. These are just some of the ways plastics are helping to create a better planet and a safer world.That is to say chemistry affect daily of our society. Chemistry drives the development of science and technology,and mankind benefit from it.。
