1) INTRODUCTION OF COLLOID (E-POSTER)
2) EXPLORING THE APPLICATION OF COLLOID
Based on my understanding of the video, colloids are heterogeneous mixtures, meaning they are made up of two or more phases that are distinct from each other. Unlike suspensions, the particles in a colloid are much smaller and are not visible to the naked eye. Colloids are all around us in our daily lives. Milk, mayonnaise, fog, and smoke are all examples of colloids. Some colloids, like gelatin and starch, can spontaneously form when mixed with water.
What I found interesting throughout this video is that colloids are used in so many everyday products. For example, I now know that the reason milk is white is because it is a colloid of fat droplets in water. I also understand why oil spills are so difficult to clean up. The oil and water do not mix together, and the waves cause the oil to break up into tiny droplets that form a colloid with water.
Did it make me more aware of colloids in my daily life? Yes, definitely. Learning about colloids has made me more aware of the different types of mixtures that exist and how they are used in everyday products. I am now more likely to notice colloids in my daily life, such as the foam on top of my latte or the mist in the air after a rain shower.
3) INDUSTRIAL-RELATED APPLICATION
RUBBER INDUSTRY
The rubber industry is one of the many industries that make use of colloids. From tires bouncing down the road to the gloves on your hands, the rubber industry owes a big debt to the fascinating world of colloids. These tiny, suspended particles play a crucial in numerous aspects of rubber production. Latex, the milky sap of rubber trees, is itself a colloid, and by adding other colloids like silica or carbon black, transform raw rubber into stronger, more resilient materials. These "microscopic helpers" give rubber diverse properties, from vibrant colors to enhanced conductivity, making thee unsung heroes of everyday rubber products.
One sticky situation the rubber industry faces with colloids is the smelly fumes released during production. These VOCs (volatile organic compounds) pollute the air and pose health risks. But there's good news! We can switch to water-based "goo" and bio-based stabilizers instead of harsh chemicals, keeping the air clean and reducing waste. Another hurdle is the use of some nasty chemicals that can harm workers. This can be tackled by replacing them with safer alternatives and utilizing advanced equipment and protective gear. By embracing greener Goo and prioritizing worker safety, the rubber industry can keep both people and the planet happy, proving that sustainable and ethical rubber production is truly achievable!
Beyond the environmental and safety concerns, producing rubber using colloids also faces the hurdles of cost and efficiency. Traditional methods using solvents and stabilizers are expensive and energy-hungry, squeezing both profits and the environment. However, hope springs eternal! We can cook up water-based processes that use less energy and resources, and even incorporate readily available recycled materials as stabilizers, bringing down the production cost. Setting up recycling loops to recapture waste latex and other materials further tightens our belts. Finally, embracing cutting-edge technologies like microfluidics and automation can streamline the whole process, reducing waste and saving valuable resources. By tackling these cost and efficiency challenges head-on, the rubber industry can pave the way for a future where sustainability and profitability go hand in hand. Who knows, with our combined brainstorming, we might even discover some unconventional solutions that revolutionize the whole game!
I acknowledge that the rubber industry is related to colloids, but I have no idea how the rubber industry problems do affect us. While colloids play a vital role in the rubber industry, their potential problems raise valid concerns about their broader impact. From price fluctuations to safety risks and environmental pollution, disruptions in colloid-based rubber production can ripple through our lives in unexpected ways. Imagine tires failing on the road, medical equipment malfunctioning, or vital resources depleting. These are just some stark examples of how rubber industry problems tied to colloid can touch our health and our future. By acknowledging these challenges and actively seeking solutions, we can pave the way for a more sustainable and resilient rubber industry, ensuring the benefits of colloids flow smoothly without jeopardizing our well-being.
