Yes, fiberglass resin does need a hardener. The resin is a polymer that requires a catalyst, typically a hardener, to initiate the chemical reaction that causes it to solidify or cure. Without the addition of hardener, fiberglass resin will remain in a liquid state and never achieve its durable, solid form. The ratio of resin to hardener must be accurately measured to ensure proper curing and strength of the final product. This mixture ratio varies by product, so it's essential to follow the manufacturer's instructions. Adding too much or too little hardener can affect the resin's curing time, strength, and overall quality.
When iron oxide is heated with carbon, a chemical reaction known as reduction occurs, facilitating the extraction of iron. During this process, carbon acts as a reducing agent. Essentially, carbon (often in the form of coke) combines with the oxygen present in iron oxide, resulting in the production of carbon dioxide or carbon monoxide and leaving behind pure iron. This reaction is fundamental to the traditional method of iron production in blast furnaces, enabling the transformation of raw iron ore into a more usable form of iron. The specific chemical equation for this reaction can vary depending on the form of iron oxide and the conditions, but a common example is: Fe2O3 + 3C → 2Fe + 3CO2. This method is a cornerstone of the steel manufacturing industry, showcasing the significance of carbon in metallurgical processes.
