advantages and disadvantages, and see some examples on polymer used in Exterior trim but first What is the Exterior trim? It is any part use on the outside body of the car to protect other parts or just to add aesthetic look on the car like bumpers, car tyers and door handles...….etc. The figure below show some exterior part made of plastic: (Plastic still has a poor image even today, being connected more with flimsy toys than the leading edge of motor industry technology But plastics are becoming
Plastic are lightweight, inexpensive and durable material, which can be shaped readily into a variety of products that are found to be used in a wide range of applications [10]. Plastics are remarkably flexible materials that provide considerable benefits as simple as packaging to complex engineering material, traditional synthetic polymers (called often as plastics), such as polypropylene and polyethylene have been synthesized from non- renewable petrochemicals and are known to cause environmental
Nowadays, no matter where, especially in Asia, plastic surgery becomes more and more popular, and it is very common also. One reasonable answer to that could be since more people feel unpleasant about their natural look, or they have been influenced by social media and the general aesthetic of society, they don’t feel waste to spend a lot of money and blood to get their ideal looks. The original idea of their aesthetic could be different in terms of they grown up in different countries, societies
made up of plastics around you. Plastic plays a big role in our environment. Not only does plastic replace materials such as paper, metal, etc. But it also has new roles only it can fill. It can be used to make bottles, cans, supermarket bags, plastic bottles, etc. The word plastic itself comes from the word ‘plasticos’, which means to be shaped or molded by heat. In this essay I will talk about whether new technologies will solve the global problem of our increasing need for plastic and how science
and they would like to have plastic surgery to become a “perfect” person. They might want to have a good looking, even the child also has the same notion. This phenomenon is ordinary to anyone and generation. However, there are lots of teenagers have plastic surgery when they are not maturing. There are more than 226,000 patients between 13 and 19 were executed plastic surgery in 2015 (Diana Zuckerman, 2012). In fact, many people are not endorsed to teens have plastic surgery before 18. Teens want
entrepreneur, was able to invent a way to make a bioplastic out of the starch from cassava, vegetable oil, and organic resins, which is a highly viscous substance that has traces of plants and other organic materials. He realized that no matter how much plastic is recycled, it is eventually going to end up in one place: the landfill. Additionally, an apparent way to improve recycling is to educate the people of this world about the hazardous effects of not recycling and trashing the environment. “By educating
Unfortunately, one of the evident disadvantages of the power-law model is that it fails to portray the viscosity of many non-Newtonian fluids in very low shear rate regions and very high. Since is generally less than one,goes to infinity at a very low shear rate (see Figure 3-5) rather than
convenient, because you do not have to bring cash with you. Besides, credit cards are easy to apply for. The little plastic thing would not cause serious social issues if a complete system is built. However, I do not agree with this kind of paying tool. I will never refer to the policy which allows students to have their own credit cards. Since the qualifications for applying for a plastic card have become lower and lower, banks even promote the project for the “Student Credit Card.” If you are twenty
Depending on your application, you should choose the right piece of material to fulfill your specific requirements. Each type comes with advantages and disadvantages. For example, metal products are strong, but cannot be used for applications such as electrical wiring (metal is a conductor of electricity.) Anyway, metal pieces are more durable than plastic ones. So, you should understand the strengths and weaknesses of each type and choose the right one for your application. Below is a list of top material
traditional manufacturing and it will revolutionise how everyone lives their everyday lives. What Materials Are Used for 3D Printing? There are many different forms of materials that can be used to create 3D objects for different purposes. Plastics: There are four common plastics that are used for 3D printing. A strong, flexible and durable material such as Nylon is used in a powder form during the sintering process. It is a pale white colour but it can be colored. It is a very reliable for 3D printers. Nylon
