Tapioca flour, derived from the cassava root, is a popular gluten-free thickener used in cooking and baking. When mixed with water or any liquid, it forms a slurry and upon heating, it thickens the mixture. Its thickening ability is activated by heat and it creates a glossy, clear finish, making it ideal for sauces, soups, and fillings. Unlike some other thickeners, tapioca flour does not alter the taste of the final product. However, it's important to mix it with a cool liquid first to prevent clumping before adding it to hot mixtures. Overheating or excessive stirring can break down the structure, causing the liquid to thin out. Therefore, for the best results, it's advisable to add it towards the end of the cooking process.

UV resin, a type of synthetic polymer that hardens under ultraviolet light, is often debated regarding its eco-friendliness. On one hand, its curing process is more energy-efficient than traditional heat-cured resins, potentially lowering its carbon footprint. Additionally, the quick curing time reduces energy usage further, and there's less waste produced in terms of unused or discarded material. However, UV resin is not biodegradable and can contribute to plastic pollution if not disposed of properly. It also contains potentially harmful chemicals that can be released during the curing process or upon degradation, posing a risk to both the environment and human health. Alternatives like eco-resins, which are more environmentally friendly, are available but may not always provide the same properties as UV resin.

Yes, Electrical Metallic Tubing (EMT) connected to Polyvinic Chloride (PVC) conduit needs grounding. While PVC itself is non-conductive and doesn't require grounding, EMT does due to its metallic nature, which can carry electrical current. National Electrical Code (NEC) standards dictate that all metallic wiring methods must be properly grounded to ensure safety and prevent electrical hazards. This is typically achieved by connecting the EMT to a grounding conductor, ensuring a path to ground is established. This connection helps in dissipating any fault current, thereby protecting both the electrical system and individuals from potential electric shock.
