- Q: Process for producing carbon fiber board
- What is the production process of carbon fiber?For the production process of carbon fiber, when the PAN based carbon fiber is produced, the polyacrylonitrile fiber, which is called the parent fiber, is firstly prepared by polymerization and spinning process. These are then placed in an oxidizing furnace and oxidized at 200 to 300 degrees celsius. In addition, carbon fibers are also carbonized in the carbonization furnace at temperatures between 1000 and 2000 degrees celsius. In addition to the conventional type of fine carbon fiber, the PAN based carbon fiber also includes coarse fiber, known as the "tow man type carbon fiber", which costs less to produce the crude fiber.If you can not understand that there are other carbon fiber net professional look, introduce a carbon fiber network via Wuxi to see you, the above information and pictures very much, I often go to their website to learn.
- Q: There is a graphite mine, looking for three experts engaged in mineral processing industry asked. They say earthy graphite, and the answer to the taste is quite different. Some say that the fixed carbon content of 15, and some say graphite grade 90%. The same sample. Some people say that very valuable, and some say that the grade is too low, worthless. I'm all confused. What do you mean by graphite grade and fixed carbon?
- No, fixed carbon is the index of industrial analysis in coal, which is used to calculate calorific value. Graphite grade refers to the content of graphite in graphite ore.
- Q: How are carbon markets regulated?
- Carbon markets are regulated through a combination of international, national, and regional frameworks that aim to ensure the integrity and transparency of emissions trading. One of the main international bodies overseeing carbon markets is the United Nations Framework Convention on Climate Change (UNFCCC), which established the Kyoto Protocol and the Paris Agreement. Under the Kyoto Protocol, an international emissions trading system was created, allowing countries to trade emission allowances through the Clean Development Mechanism (CDM) and Joint Implementation (JI) projects. The CDM and JI projects are approved and monitored by the UNFCCC, which ensures that emission reductions are real, measurable, and additional to what would have occurred without the project. The Paris Agreement, which succeeded the Kyoto Protocol, introduced a new market mechanism called the Sustainable Development Mechanism (SDM). The SDM aims to promote sustainable development and help countries achieve their climate goals by enabling emission reductions and removals through projects in developing countries. At the national and regional level, governments and regulatory bodies play a crucial role in the regulation of carbon markets. They establish legal frameworks, set emission reduction targets, and develop domestic emissions trading systems. These systems typically involve the allocation of emission allowances to companies or sectors, monitoring and reporting of emissions, and the trading of allowances on regulated platforms. To ensure the integrity of carbon markets, strict regulations are put in place to prevent fraud, double-counting, and other forms of market manipulation. Independent verification and accreditation bodies are responsible for auditing emissions data and project methodologies to ensure compliance with the established rules and standards. Furthermore, market oversight and enforcement bodies are established to monitor and enforce compliance with the regulations. These bodies have the authority to investigate and penalize any non-compliance, including imposing fines or revoking emission allowances. Overall, the regulation of carbon markets involves a complex network of international agreements, national legislation, and regulatory bodies. The aim is to create a robust and transparent market that incentivizes emission reductions and supports the transition to a low-carbon economy.
- Q: What are the benefits of carbon fiber?
- Carbon fiber (carbon fiber, referred to as CF) is a new kind of fiber material with high strength and high modulus fiber with carbon content of more than 95%. It is a flaky graphite, microcrystalline and other organic fibers stacked along the axial direction of the fiber, obtained by carbonization and graphitization of microcrystalline graphite material.
- Q: How are fossil fuels formed from carbon?
- Fossil fuels are formed from carbon through a natural process that takes millions of years. When plants and organic matter die, they get buried under layers of sediment and undergo decomposition. Over time, intense heat and pressure from the Earth's crust transform this organic matter into fossil fuels such as coal, oil, and natural gas. These fuels contain stored energy in the form of carbon compounds, making them valuable sources of energy when burned.
- Q: What is carbon nanocomposite coating?
- Carbon nanocomposite coatings, composed of carbon nanotubes or other carbon-based nanoparticles dispersed within a matrix material like polymer or metal, serve as a protective coating for diverse surfaces. The primary goal of these coatings is to enhance the mechanical, thermal, and electrical properties of the material being coated. By incorporating carbon nanoparticles, the coating gains strength, hardness, and wear resistance, resulting in increased durability.

- Q: What role does carbon play in photosynthesis?
- The role of carbon in photosynthesis is crucial because it serves as the primary element utilized by plants to generate organic compounds. In the process of photosynthesis, plants absorb carbon dioxide from the atmosphere and employ it to synthesize glucose, a simple sugar that acts as a foundational component for more intricate carbohydrates like starch and cellulose. This entire process takes place within the chloroplasts of plant cells, specifically in the stroma of the chloroplast. It is in this location that the enzyme RuBisCO facilitates the fixation of carbon dioxide into an organic molecule called PGA (phosphoglycerate). By means of a series of reactions referred to as the Calvin cycle, PGA is transformed into glucose, which can be either stored as energy or utilized for growth and reproduction. To sum up, carbon is indispensable to photosynthesis since it supplies the necessary raw material for plants to self-generate their own sustenance and maintain life.
- Q: What is the relationship between carbon emissions and deforestation?
- The relationship between carbon emissions and deforestation is closely intertwined. Deforestation refers to the permanent removal of trees and vegetation in forests, usually to make way for agricultural land, urban development, or logging. This process releases large amounts of carbon dioxide (CO2) into the atmosphere, contributing to greenhouse gas emissions and climate change. Trees play a crucial role in mitigating climate change as they absorb CO2 from the atmosphere through photosynthesis and store it in their tissues. When forests are cleared, this carbon storage capacity is lost, and the carbon previously stored in trees is released back into the atmosphere. Deforestation is estimated to be responsible for around 10% of global greenhouse gas emissions. Furthermore, the burning of forests, a common practice during deforestation, also contributes to carbon emissions. When trees are burned, the stored carbon is released as CO2, exacerbating the greenhouse effect. This is particularly significant in tropical regions where deforestation is prevalent, such as the Amazon rainforest. Conversely, reducing deforestation and promoting reforestation can help mitigate carbon emissions. By preserving existing forests and planting new trees, we can enhance carbon sequestration and reduce the amount of CO2 in the atmosphere. Forest conservation and restoration efforts are crucial components of global climate change strategies, as they not only help combat climate change but also preserve biodiversity and provide vital ecosystem services. In conclusion, the relationship between carbon emissions and deforestation is clear: deforestation leads to increased carbon emissions, while forest conservation and reforestation efforts help reduce carbon dioxide levels in the atmosphere. It is essential to prioritize sustainable land-use practices and support initiatives that protect and restore forests to mitigate climate change effectively.

- Q: Carbon Finance: Carbon Finance
- Carbon finance does not have a unified concept. Generally speaking, it refers to all financial activities that serve to limit greenhouse gas emissions, including direct investment and financing, carbon index trading and bank loans. The rise of "carbon finance" stems from changes in international climate policy and, precisely, two international conventions of great significance - the United Nations Framework Convention on climate change and the Kyoto protocol. Carbon finance definition: improved use of financial capital to drive the environmental rights and interests, to the laws and regulations for support, the use of financial means in the market platform makes carbon financial products and derivatives trading or to circulation, and eventually achieve a low-carbon development, green development and sustainable development objective. The United Nations Conference on environment and Development held in June 1992 in Brazil, Rio De Janeiro, more than 150 countries have established the "United Nations Framework Convention on climate change" (United Nations Framework Convention on Climate Change, referred to as the "Framework Convention"). The ultimate goal of the Convention is to stabilize atmospheric concentrations of greenhouse gases at levels that do not harm the climate system.
